Abstract

One quality that sets humans apart from all other species of known life is the ability to

think, reason, and communicate. The job of education is to enhance and develop these

skills to the highest degree possible. At the heart of human progress is logical/critical

thought. This research attempts to begin to answer the question: Are current educational

practices adequate in transferring critical thinking skills from science class to real life

applications, and can activities be developed to improve the transfer of critical thinking

skills across topics? This skill is crucial to ensuring that a responsible public is able to

make decisions based on the best information available in a democratic society.

Skepticism and the tools of skepticism can be one of the most effective ways of

accomplishing that task. Students’ critical thinking skills were assessed across multiple

topics to ascertain their use and development of critical thinking skills. Preliminary

results show that critical thinking skills do not transfer well from topic to topic, growth

was demonstrated, and many confounding factors complicate the issue beyond simple

critical thinking.

Page 2: Skeptical Thinking in the Classroom and its Impact on the

Background In a day where science and technology has achieved things that no one thought humanity

could possibly attain 500 years ago, superstition and credulity are still prevalent in

today’s society much as they were 500 years ago. Science and technology seem to be

progressing at an ever increasing rate, and every day the human race becomes more

dependent on science and technology while the vast majority of the general public’s

understanding of science is sketchy at best. People bask in the glories that science and

technology bestow upon them, yet mistrust and ridicule scientists as social misfits, nerds,

and quacks. Diseases like smallpox, which have devastated people for centuries, have

been eradicated. More people are fed today even though there are decreasing amounts of

farmland available to farm. Less than 70 years after the first powered flight man had

landed on the moon. In a democratic society the people will be electing representatives

to make political decisions for them. Many of these decisions will be on controversial

topics such as: stem cell research, cloning, abortion, the space program, global warming,

alternative energies, nuclear energy, and the ozone hole, along with problems not named

or as of yet undiscovered. The only way the public can possibly make wise decisions on

matters such as those is if they have a good understanding of science, faith in the

scientific method, the ability to look at the arguments from all sides skeptically, and be

able to discern what arguments hold water. Not many people have the time to become

versed on all the details of every topic under scrutiny. As a result, they must rely on the

information that comes from the media, politicians, special interest groups, corporations,

and religious leaders. Teaching students to think skeptically about claims in general, and

how to evaluate information in an objective way so that they can recognize valid

information from unsubstantiated or misleading information, is the key to making the

best decisions on any topic. I feel that a student that can evaluate information in a

skeptical and logical manner has better tools for life in the 21st century than a student that

just knows a lot of science facts, formulas, and can get the correct answer to a problem on

a test. As much as I would love for all my students to leave my classroom with a love of

science equal to mine, I am not that naïve. Most will not remember how to find the

resultant force applied to an object pulled at a 40 degree angle from the normal, but if

they learn skeptical/critical thinking skills they will be better scientific thinkers that are

better able to make informed decisions especially when it comes to matters having to do

with science. I have witnessed how skills are not transferred from one lesson to the next

or that the skills learned in one class does not transfer to another class. A common

example of this is that students have no problem solving equations in math class, but can

not solve the same type of problem in science class. I believe that logical/critical

thinking skills used in the classroom are not used or transferred in proportion to real life

situations that may require it.

Research Question: Do critical thinking skills transfer from science class to real life applications, and can

activities be developed to improve the transfer of critical thinking skills across topics?

I am not sure if there is a single main cause for the lack of critical thinking skills in

students today. There seems to be several stages in the development of critical thinking

Page 3: Skeptical Thinking in the Classroom and its Impact on the

skills as it pertains to belief and the way information is evaluated. (Margarita Limón ) I

believe that it is a multitude of factors that end up conspiring to make a more credulous

student. Some of these may include:

a) The propagation of unsubstantiated claims.

a. Disguised as science otherwise know as pseudoscience. Many times an

idea or event is termed as fact or as having been confirmed by science and

has little or no connection to science. These types of claims can mislead

people, leaving them with a greater distrust of real science. They are often

presented in a charismatic way with flawed logic and no method of

disproving the claim. People can be fooled because the claim makes them

feel good or taps into a desire for that person. They can be made

innocently or with a desire to help, but often they are made by people that

know they are false to further their agenda.

b. Media outlets that do not check facts or the veracity of claims. Many

programs in the media are only interested in ratings, and the debunking of

fallacious claims is usually a casualty in the ratings race. Extraordinary

claims will get extraordinary ratings; however the evidence is far less than

extraordinary and many times fraudulent.

c. Ascribing supernatural causes to mundane although uncommon

experiences. People can misperceive things and come to wrong

conclusions. When the stories are told in a sincere impassioned manner

other people are much more likely to believe the story as fact.

b) The superstitions of long ago are still part of the thinking today.

a. Superstitions are part of the folklore of the human species. The origins of

most can be traced and explained, but many people still take them

seriously and can relate convincing anecdotal evidence to back up those

claims.

b. Urban legends may also be considered as a type of modern superstition as

many urban legends will tell you not to do something or their will be a

consequence.

c. Old wives tales are also a type of superstition that is often erroneous in

their claims. It is a form of believing a so called fact with no real evidence

of its veracity.

c) Survival traits imbedded in the genetic code that may not be necessary in this day

and age may lead to a more credulous acceptance of the story. (Van Gelder p. 5

“Teaching critical thinking”)

a. There may have been traits that helped humanity survive and evolve to

this point that increases people’s credulity. Perhaps the coming together

under charismatic arguments gave our ancestors a survival advantage that

persists today even though it is no longer essential to our survival. For

example: It may have been advantageous for people to group together, and

emotional arguments are the means by which that happens.

b. The proliferation of many ancient religions may have been a byproduct of

these traits

i. Some religions today put forth extraordinary claims with little hard

evidence and a lot of anecdotal evidence. Belief in religion may be

Page 4: Skeptical Thinking in the Classroom and its Impact on the

the seed that makes the leap to other credulous claims more

palatable and believable.

I hope that through this study I will be able to ascertain to what extent critical thinking

skills from the classroom are transferred to the real world, how to identify students that

are deficient in skeptical thinking, and gain insight on how to improve critical thinking

skills in the real world.

Methodology

While there are many ways to address and assess critical thinking in the classroom, one

of the ways that is largely ignored is when it comes to superstition and paranormal

events. As a result, I have crafted these exercises myself. It seems as though I had a very

clear idea of what I was assessing, but had a difficult time designing exercises that could

possibly assess it. Once I created them, I had an even more difficult time assessing them

quantitatively. My basic methodology was to establish a baseline for students’ attitudes,

present students with claims of paranormal activity, have them evaluate the claims, and

give a response as to how much credibility each claim had. Students used written

responses in most cases to ascertain their logical/critical thinking skills.

1) Student feelings about science

a) Students wrote a short one paragraph essay on their feeling about science in

general. They were to write about what they thought it was, if it was good, if they

liked it, if it was hard, etc.

i) I use this every year to get to know my students better and to help me target

students that have a poor attitude about science. That way I see it as a

challenge to get them interested in science and to achieve at a high level.

ii) It helped me establish a baseline for each student as to their attitude towards

science for this project.

2) TOSRA test of scientific related attitudes

a) The Test Of Science Related Attitudes (TOSRA) was developed by Professor

Barry Fraser of Curtin University of Technology in Bentley, Western Australia. It

is aimed to examine the attitudes of students towards science and their "scientific

inclination". It is a 70-item self-report instrument that is designed to obtain

information about a person's attitude toward science. (See index for the test)

i) Assessment

(1) Students took the test in November and it was scored to give the students a

baseline to compare further activities as to their growth in skeptical/critical

thinking skills.

(2) Students were scored as per the TOSRA scoring guide.

3) Hope Diamond Essay

a) Students were given two articles to read and write an essay on the two articles.

One article was on the curse of the Hope Diamond and all the trouble that it has

Page 5: Skeptical Thinking in the Classroom and its Impact on the

caused through the years. The other article was on debunking the curse of the

Hope Diamond.

b) Students were then required to write a one page essay explaining which article

they felt was more convincing. They were to use examples from the articles to

support their position, and to include their own ideas or life experiences into the

essay.

i) Assessment

(1) Students were assessed by their logical reasoning skills on a scale from -2

to 2, with 2 being high critical thinking skills. Students that found the

curses debunked article more credible scored positively and students that

found the curse article more convincing scored negatively.

(2) I was also looking at the strength of belief or disbelief in the curse

coloring their perception of the articles. Statements like: “I do not believe

in curses to begin with” or “Curses are real” gave me insight as to the

relative impact of the readings.

4) Astrology activity

a) Students were given a sheet of paper to describe how their day went. They were

to include how they were feeling at different times of the day, if anything good or

bad happened.

b) Students were then given their horoscopes for the previous day and asked to

answer questions as to how accurate their horoscope was. They were to rate it

from: Very accurate, more accurate, less accurate, and not at all accurate.

c) Assessment

i) We then did a statistical analysis of the whole class on the accuracy of the

horoscopes.

ii) Students then answered questions regarding astrology

(1) Students then suggested that we do it again tomorrow and check the

accuracy of astrology.

(2) The following day we repeated the activity.

5) Haunted House Activity

a) Students were given a pre-read activity asking how they felt about ghosts and

hauntings.

b) Students were then given an article “How to Haunt a House” by Benjamin

Bradford to read.

c) They were asked questions regarding the article and their opinions about the

haunting in general.

i) Assessment

(1) The students were rated as to whether the article moved them towards a

very critical analysis of ghosts (2), a more critical analysis (1), unchanged

analysis (0), less critical analysis (-1), much less critical analysis (-2)

6) Ending activity

Page 6: Skeptical Thinking in the Classroom and its Impact on the

a) Students answered a short questionnaire on the various activities in the project.

They were asked if any of their views on the various topics covered were changed

in any way.

b) Grades were also asked to rank different paranormal and pseudoscientific claims

as to how credible they thought they were.

i) Assessment

(1) I ranked them from -2 to 2 as to how they examine extraordinary claims

made by people or the media. 2 being very critical, -2 being very

credulous.

Findings

TOSRA The TOSRA test uses a Likert response scale that gives the highest positive score of 5 to

Response that are most favorable to science, 3 to a neutral response, and a 1 to the most

negative response. I separated the scores into ranges to get an initial category for the

students. The highest possible score is a 350, while the lowest possible score is a 70. I

separated that possible spread of scores into six ranges:

70- 140 very negative attitude towards science

141- 175 negative attitude towards science

176- 210 neutral with negative leaning attitude

211- 235 neutral with positive leaning attitude

236- 280 positive attitude towards science

281- 350 very positive attitude towards science

There were only three students that fit in the 176- 210 neutral with negative leaning

attitude category. Two students scoring in this range were a surprise to me. Students 10

and 8a are very good students. Student 10 has shown evidence of grade motivation but

not too much intrinsic interest in the subject matter. Student 8a is probably the best

student in the class, and always asks interesting questions that add to the lesson and

expand understanding. Student 8a seems to have a real zest for science class.

Student 6 was the third one scoring in that range. I was not surprised to see that student

there. The student has a positive approach to class, but often will ignore information that

does not fit their previous ideas or model of the topic.

There were eight students that fit into the 211- 235 neutral with positive leaning attitude

category. I expected two students to score higher and one student to score lower based

on classroom performance. Students 5 & 11 get very good grades and seem to have a

good general understanding of science. Student 4a shows no interest in science and even

seems repelled by it at times.

There were nine students that fit in to the 236-280 positive attitudes towards science

category. There was only one surprise in this group. Student 5a has not shown much

interest in science in class, and almost seems resistant to science work academically.

Page 7: Skeptical Thinking in the Classroom and its Impact on the

There was 1 student that fit in to the 280- 350 very positive attitude towards science

category. I expected that student to score high, as the student achieves at a high level and

shows a real interest in science.

From the TOSRA test most of my students have a positive attitude towards science, and

the three that scored the lowest scored close to a positive view. This is encouraging to

me as a science teacher.

Hope Diamond Essay

I use a Likert response scale from -2 to 2 in rating student responses.

I scored six students negatively and one student as neutral.

two of the students that scored negatively in this exercise are Hindu (1, 12). From one of

those essays a student says that they are taught to believe in curses as part of their

religion. I believe that religious bias may have a large impact on how skepticism is

applied in an individual. In this case it seems to be hampering those students

development of critical thinking skills.

Two students that scored negatively (10, 4a) had trouble identifying which article had

more reliable facts. Those two students seem to not have read the “Curses Debunked”

article or totally ignored it. There is no mention of it in either of the essays.

The student that scored neutral (6a) straddled the fence and did not come to a definitive

conclusion as to which article was more convincing.

Out of the rest that scored positively, three of them (8, 11, 7a) did an outstanding job

using logical thinking skills to present a well articulated argument.

Astrology Activity

I use a Likert response scale from -2 to 2 in rating the students.

I listed the student s’ Likert scale ratings of how their day went compared to their

horoscope. The data produced a perfect bell curve: Three were very close, seven were

somewhat close, seven were mostly wrong, and three were totally wrong. A class

discussion followed the results of the data. We analyzed what the data meant and

concluded as a class that it is as valid as tossing a coin. In isolated cases (their own

personal horoscope) it could validate, disprove, generally support or refute astrology, but

in a large sample a better picture of the validity of astrology emerges.

Students then completed their questions. Upon grading the students responses

I was shocked to find that five students still clung to the idea that astrology was valid.

Some even found it more convincing.

Two students (6, 4a) were believers to begin with and responded that the activity had no

effect on how the viewed astrology.

Page 8: Skeptical Thinking in the Classroom and its Impact on the

Two students (5, 7a) had a weak belief in astrology, but the activity had no effect on how

the viewed astrology.

One student (11) was a surprise. The student uses good logical reasoning skills in class,

but ignored the data and saw what they wanted to see in the data; a confirmation of

astrology. The student seemed to be fixed on how accurate the horoscope was for them

on that occasion.

On the next day we quickly examined the accuracy of their horoscopes, and the data

again formed a bell curve.

Five were very close, five were somewhat close, six were mostly wrong, four were totally

wrong.

Although two more were very close, there were two less that were somewhat close.

There was one more totally wrong and one less mostly wrong.

This activity showed me how powerful ideas based on belief really are. I was going on

the assumption that when a person is faced with solid evidence they would have to reject

an erroneous idea. This is not just teaching facts or processes, but changing the way a

person thinks. It seemed as though there was a prism that students viewed the data from

this exercise that bent the results to fit their idea of what would happen.

Haunted House Activity

A Likert response scale from -2 to 2 was used in rating student responses.

A response of 2 gave very good reasoning as to the supposed paranormal evens in the

house, and a -2 for a response that is unreasonable in light of the article.

This activity showed the biggest spread between all of the responses. It did not seem to

change student’s ideas on ghosts. I infer that this is because it was one specific instance

that a haunting was decisively disproved, and that one instance does not disprove all

other reported instances.

Nine students (2, 4, 7, 8, 10, 1a, 3a, 7a, 8a) had a very positive reaction to the article.

Three stated that they had no belief in ghosts to start with. (2, 1a, 8a) The rest stated that

they believe in ghosts, but the house in the article just was not haunted.

One student scored a 1 (3) as the student stated a previous and continuing non belief in

ghosts, but all questions were not answered.

Five students received a neutral score. (5, 12, 4a, 5a, 6a) Their views mostly start with a

belief in ghosts, but use good logic when it applies to this specific instance. Their main

view remains unchanged.

Three students received a score of -1. (6, 11, 2a) They showed little to no movement

from a very solid belief in ghosts, even in this specific case.

Page 9: Skeptical Thinking in the Classroom and its Impact on the

One student received a -2. (1) The response shows a total belief in the ghost hunter TV

shows and disregard for any evidence that contradicts that view.

Findings Data Analysis

I assembled the data from the previous activities into a table. The table shows the ratings

and scaled scores for the students in all three activities.

I then combined the scores and came up with a rating scale as to how high they were in

skeptical thinking. The most critical thinkers (highest score) would have a score of 6/3,

and the least critical thinkers would have a lowest possible score of -6/3. A top score of

6/3 is scaled to 200, 5/3 is scaled to 183, 4/3 is scaled to 166, 3/3 is scaled to 150, 2/3 is

scaled to 133, 1/3 is scaled to 117, 0/3 is scaled to 100, -1/3 is scaled to 83, -2/3 is scaled

to 67, -3/3 is scaled to 50, -4/3 is scaled to 33. -5/3 is scaled to 17, -6/6 is scaled to zero.

An analysis of the TOSRA range and the activities range shows that the TOSRA test

showed a general correlation between the two. 70% of the students that scored very

positive or positive scored in the same range from the overall activities (5 0f the 7

improved and 2 held constant), while 30% scored lower. 50% of the neutral positive

increased, while 50% of the neutral positive decreased. 33% of the neutral negative

stayed the same, while 66% increased.

The correlation was not as strong as I had hoped. The weakness of the correlation of the

data may be an indication of the non-transferring nature of logical/critical thinking skills.

The data also indicates that students that have the most positive attitude towards science

generally are less credulous than students with a poorer attitude towards science. As

scientific attitudes decrease the correlation becomes less evident.

Series1

Out of the eight students that scored the maximum in the activities six scored above 245

on the TOSRA test, but one student scored under 200. Out of the three students that

scored the lowest on the TOSRA test only one stayed in the negative range.

The activities scaled range gives a better description as to how their skeptical thinking

skills are developed at this point. The data from the different activities shows how

inconsistently skeptical thinking is applied when it comes to different topics. Students 5,

6, 12, & 4a all scored negatively in all of the activities.

Activity Analysis

Student 1 scored highest in the horoscope activity, but scored lowest in the Hope

Diamond and Ghost activities.

Student 7 scored highest in the ghost activity, lowest in the Hope Diamond and low

positive in the horoscope activity

Page 11: Skeptical Thinking in the Classroom and its Impact on the

Student 11 had one of the best analysis of the Hope Diamond, but scored lowest in the

horoscope and low in the ghost activity.

Student 2a scored the highest in the Hope Diamond and the Horoscope activities, but

scored negatively in the Ghost activity.

These examples show that skepticism is not a monolithic way of thinking, but changes

from person to person and topic to topic. It seems as though there are many factors that

go into an individual’s critical thinking process. Some of the factors that were revealed

by the student responses were:

1) Religion: Religious beliefs that are instilled from birth or a very young age have a

profound effect on the way a student will analyze data. Many students misinterpret,

ignore, or disbelieve contradictory evidence.

a) Misinterpretation

i) Innocent Misinterpretation: Students that are guilty of misinterpretation may

be new to logical investigation and may just need to sharpen their data

analysis skills

ii) Biased misinterpretation: Students that are guilty of biased misinterpretation

have an idea of what they believe the data should be and make the data fit

their invalid interpretation.

b) Ignoring evidence: Students that are guilty of ignoring evidence will put forth

their invalid view without addressing the factual contradictory evidence.

c) Disbelieving contradictory evidence: Students guilty of disbelieving

contradictory evidence cling to their invalid views and believe that the scientific

data is wrong or made up to discredit a point of view.

2) Mass media/Popular Culture:

a) Many of the students, in the ghost activity in particular, say their invalid

assessment of the data presented was fueled by television programs such as Ghost

Hunters on the Sci-Fi channel. These programs hook people with a flashy

presentation, charismatic performers, scientific sounding language, and scientific

sounding equipment. The main problem with the programs is that they do not

faithfully follow the scientific method or the principle of Occam’s razor when

evaluating their so called data.

3) Personal experience:

a) Friends or family’s anecdotal stories of a paranormal experience. Many students

related experiences that family members had with ghosts, fortune tellers, curses,

psychics, and astrology. The students were more likely to believe an impassioned

sincere story from a friend or relative than anything presented by an article or

teacher. Most of these stories came out during class discussions. The way the

students told the stories were very impassioned and sincere. Most of the

discussions regarding a story like that ended with the student saying something to

the effect of: “I don’t care what you say, I believe my Aunt” or “Science can’t

prove that it didn’t happen”

b) Student personal experience: The majority of these stories came out during the

discussions as well. The few students that claim to have experienced an event

related that their experience was very convincing and it would take a lot to

convince them otherwise.

Page 12: Skeptical Thinking in the Classroom and its Impact on the

I then combined the scores and came up with a rating scale as to how high they were in

skeptical thinking. The most critical thinkers (highest score) would have a score of 6/3,

and the least critical thinkers would have a lowest possible score of _6/3. A top score of

6/3 is scaled to 200, 5/3 is scaled to 183, 4/3 is scaled to 166, 3/3 is scaled to 150, 2/3 is

scaled to 133, 1/3 is scaled to 117, 0/3 is scaled to 100, -1/3 is scaled to 83, -2/3 is scaled

to 67, -3/3 is scaled to 50, -4/3 is scaled to 33. -5/3 is scaled to 17, -6/6 is scaled to zero.

Ending Activity

The ending activity was a type of survey comprised of a survey of seven

paranormal/pseudoscience disciplines, two essay questions on how their views have

changed regarding the topics covered in the activities and, have the way they view

information in the media changed.

I in turn interpreted the questions and survey, and then scored them using a Likert scale.

A high score of two on the scale showed that the student started with good critical

thinking skills and had a skeptical rating for the items found in the survey, or they

showed significant movement from a more credulous way of thinking to a more critical

way of thinking. Students 1a, 3a, 5a, & 7a in particular indicated a much better attitude

towards using skepticism for paranormal claims

A score of one indicated that the students were more skeptical of the sources in the

media, but still harbored beliefs in some paranormal events or they are more skeptical

about the paranormal in general, but still believe in them to some extent

A score of zero indicated that students claim to be more skeptical, but rate belief in

different paranormal events very high.

Students 5 &13 scored negatively as their answers show movement towards a less critical

evaluation of information.

I compared the data from the ending activity to the scaled activities total & range.

The comparison shows that of the highest scorers in the ending activity also scored high

in the activities total and range, except students 10 & 11. The interesting thing about

those 2 students is that they are 2 of the highest achieving students in the class. In

student 11’s case it shows that she has openness to changing her opinion, even though she

still has a strong predilection towards believing in some paranormal phenomena. Student

10 scored in the neutral positive range for the activities and shows a similar openness to

Conclusions:

1) Evidence seems to indicate that Critical thinking skills are not transferred to real life

activities effectively.

2) My research has indicated that students can increase their critical thinking skills.

Research into critical thinking is mainly concerned with the general thinking processes of

students, and does not see preconceived beliefs as a factor. (Black, S. Teaching Students

Page 14: Skeptical Thinking in the Classroom and its Impact on the

to Think Critically) My research shows that students have critical thinking skills, but

many do not apply them uniformly. Research conforms with some available researchal in

showing that the way critical thinking skills are taught in schools falls short in the three

areas of: Noncritical thinking techniques are inadvertently anti-critical, Students'

concepts have already been shaped by noncritical thinking, and Students need to learn to

think in terms of central concepts across the curriculum. (Nosich,Gerald M. “Problems

with Two Standard Models for Teaching Critical Thinking”) My research reinforces Mr.

Nosica’s research in that students’ concepts had already been formed by non-critical

thinking. My research activities have shown me those students with very good critical

thinking skill in answering questions in class will not always apply those skills when it

comes to a real life decision like the validity of a superstition.

The activities that were used in my research indicate a general correlation between

science students with a positive attitude towards science and the transference of critical

thinking skills to real life situations, but that correlation breaks down as their attitude

towards science falls. That general correlation also breaks down when individual

students are examined. From activity to activity each individual student different varying

degrees of transference occurs creating a weaker than desirable correlation. Even where

the strongest correlation exists there are some stark differences in logical thought when

different activities are compared. This comparison of the responses of differing activities

between different students reveals the complexity of the problem of critical thinking

skills in schools. It shows that students can adapt their skills in getting correct answers in

school, but do not necessarily incorporate critical thinking skills to their lives. A question

that arises from this observation is: Do the students really learn critical thinking skills or

do they learn how to give the teacher an acceptable answer to get a passing grade? This

is most evident when one of the highest achieving students with an average scientific

attitude has no real critical thinking compass to guide them, such as student 5. The

student has learned how to answer higher order questions in my science class with well

reasoned logical answers, but abandons all of those skills when a grade is not involved or

their personal opinion is involved. This was a student that I expected to be near the top

of the class for skeptical thinking based on the class work to date, but is one of the lowest

skeptical thinkers in the class from the activities contained in this study. My assessment

for class assignments show a much different student in regards to critical thinking. On

the other hand student 5a shows little initiative in class and gives short or incomplete

answers to higher order questions in class, but scored the highest when it came to the

activities presented in this study. I have shown two of the starkest differences as

examples, but many students show that same kind of abandonment of critical thinking

when it comes to specific situations, and some students seem to have a good critical

thinking skills when school assessments do not show it. These findings are preliminary,

and need to be improved. Further tests are required to firmly establish my conclusions.

My findings also reveal that the lack of skeptical thinking is not necessarily a school

instituted problem, but something a student brings to school from their experience with

their family, friends, media, and religion. Many of which has a strong hold on the way a

students approaches problems and the rewards (intrinsic and extrinsic) they get from a

particular solution to a particular problem. These influences, although diverse, can

possibly be mitigated or eliminated by a more effective critical thinking curriculum that

stresses logical thinking, coupled with a strong scientific understanding of nature.

Page 15: Skeptical Thinking in the Classroom and its Impact on the

Further testing of this hypothesis needs to be established to get a more definitive answer

to that question.

The most difficult aspect of this project was trying to develop activities to assess a

student’s actual skeptical thinking skills. I wanted to know how the students thought for

themselves not for a teacher, grade, or any other reason other than their own thinking

process. I feel I was somewhat successful in developing activities that assess that goal,

but need refinement to improve their effectiveness. One thing that I would change is the

addition of a survey in the beginning of the project to further establish a baseline as to the

students’ belief in paranormal events, and the skeptical evaluation of information. An

introductory survey would give a much better measure of the growth of each individual

student as well as a better correlation in skeptical thinking for the group. The

assignments in general give a good indication as to where each student stands for each

topic addressed. Some more activities need to be developed to test not only other

paranormal phenomena, but should also include pseudoscientific phenomena as well.

The Hope Diamond activity is very effective at assessing a student’s belief in curses, and

also in how the student’s decide which argument is credible. The discussion that

followed brought up valid points but I feel that it was ineffective in establishing a

concrete way to evaluate material. A closing activity that leads or instructs students as to

how to evaluate sources of information would be beneficial. Care must also be taken as

to not cross the line into attacking any student’s religious beliefs. A Hindu student

revealed that belief in curses was part of his religious education. This type of care must

be taken into account when a religious belief may cross over into an activity such as

demonic possession and other supernatural religious beliefs.

The astrology activity achieved ideal statistical data, but again the post activities were not

sufficient to dislodge belief in Astrology. Improvements need to be made that will

reinforce critical analysis of the data. Some students refuse to accept any hard evidence

that astrology is no more accurate than chance alone. This problem may go deeper into

some psychological reasons for hanging onto a belief or idea. I have discussed this

project with my students after my data was collected and a discussion on astrology

ensued. The students wanted to compare the previous day’s horoscope with the way their

day actually went. Two interesting things happened. I was unable to locate any

astrology website that had the previous day’s horoscope available. This indicates that

checking the accuracy of horoscopes is not in their best interest. The second interesting

thing that happened was that horoscopes from Two different astrology websites for

Gemini on that day were contradictory. One told of a foreboding bad day, and the other

one said to get out and enjoy the great day ahead. This seemed to have a greater effect

than the statistical data from the actual activity.

The Haunted House activity’s main strength was to see if students could put their

personal beliefs about ghosts aside, and evaluate the information objectively. Most

students were able to do that. The discussion that followed seemed the most passionate

from the believers out of all the activities. Many of them watch the Ghost Hunters

television program. I tried to reason with them that it was on the Sci-Fi network, which

Page 16: Skeptical Thinking in the Classroom and its Impact on the

means science fiction, and fiction is not real. One of the things that make some of these

paradigms difficult for the people to make a clear decision based on facts is that many are

insulated from disproof. When haunting and the like are debunked there are always

hundreds more that have not been debunked and more cases arise everyday. That

coupled with the pseudoscience of ghost hunting that ensnares people in a guise that it is

hard science, while not employing the integral method, adds to the proliferation of an

unsubstantiated claim. A viewing and careful debunking of one of the Ghost Hunter

programs as a class activity may be a more effective test for the ghost activity.

The ending activity can be broadened to include more questions that probe students’

opinions better. That coupled with an effective introduction will give a better assessment

on how student thinking has evolved.

I think that the main hindrance to a more effective research project was my inexperience

as a researcher. Input from peers and colleagues would have improved the project

immensely. Brainstorming activities and assessments with others would have yielded

better results. A broadening of subject matter to include conspiracy theories may have

been a better choice. Starting by honing the students’ critical thinking skills as to reliable

sources and how to distinguish fallacious arguments from valid ones using conspiracy

theories could start the students on a better critical thinking path. Introducing

pseudoscientific claims like free energy to be evaluated would have made a good second

step. Finishing the project with the paranormal would have given the research a broader

palette of phenomena to see student distribution of what topics were most prevalently

credulous and would show student growth in critical thinking in a much clearer light.

After I have finished here at the University of Penn I plan to find other researchers to join

with to study the subject further. If the goal of education is to produce true critical

thinkers, then research into the propensity of people to be credulous and effective

practices that help students not fall into credulity are needed to guide students into being

better critical thinkers in their lives.

Teaching critical thinking skills is often endorsed as a means to help students

develop their abilities to navigate the complex world in which people live and, in

addition, as a way to help students succeed in school. Over the past few years, this

author explored the idea of teaching critical thinking using the World Wide Web

(WWW). She began in-depth research on the topic to understand what critical

thinking entails and the potential for art educators to use the WWW to help their

students develop critical thinking skills. This article begins with a review of the

history of critical thinking and some current ideas on the topic. Then, the author

explains her working description of critical thinking and how critical thinking is

currently articulated in discussions of the WWW in schools. She concludes with

ideas for teachers related to developing critical thinking in art classrooms using

the WWW. (Contains 1 figure and 3 endnotes.)

Research on epistemological beliefs has clearly increased in the last decade. Even

though the construct is clearer and relevant data are being collected, there are

important theoretical and methodological issues that need further

clarification. One of them is the debate about the domain generality-specificity of

epistemological beliefs. I argue that there are both theoretical and methodological

difficulties that hinder a more fruitful approach of the domain generality-

specificity debate. Differences in goals and scope of the diverse

conceptualizations about epistemological beliefs and how they devise the role of

content-domain and context are a major source of difficulties. Methodological

problems such as whether such epistemological beliefs can be measured "in

isolation"--free of content and context influence--or the impossibility of collecting

direct measures of epistemological beliefs may influence how the domain

generality-specificity question is approached. Some suggestions about how these

difficulties may be overcome are developed. The relevance of exploring

epistemological beliefs across domains and across contexts is emphasized.:

In this article, the author stresses that teachers need to teach their students to think

critically and to reason their way. One prerequisite for teaching critical thinking is

a classroom climate of high expectations, teacher warmth and encouragement, and

pleasant physical surroundings. Schools should see to it that students become

progressively more disciplined in their reasoning, and more self-critical and self-

directed in the process and products of their thinking as they advance through the

grades. She also states that the students need opportunities to analyze their own

thinking according to standards of clarity, accuracy, relevance, logic, and fairness.

Moreover, she notes that teachers should give necessary information and thinking

tools to solve problems that focus more on affective and cognitive features of

learning; and for students to become good critical thinkers, teachers must be good

thinkers themselves. Furthermore, she discusses some of the possible things that a

teacher should do in order to develop the students' thinking skills.

This article draws six key lessons from cognitive science for teachers of critical

thinking. The lessons are: acquiring expertise in critical thinking is hard; practice

in critical-thinking skills themselves enhances skills; the transfer of skills must be

practiced; some theoretical knowledge is required; diagramming arguments

("argument mapping") promotes skill; and students are prone to belief

preservation. The article provides some guidelines for teaching practice in light of

these lessons.

Today's highly technical information society is marked by constant change. To be

competent, functional, and prepared to deal with the future, students need to be

able to analyze, question, and evaluate information critically. Therefore, the

educational community has renewed interest in teaching critical thinking.

Unfortunately, educational practices often concentrate on rote knowledge of facts

while neglecting problem solving skills. This paper addresses the effectiveness of

classroom debate as a tool to teach problem solving skills. The strategies given

enable high school teachers to prepare their students for classroom debate.
