Background

Increasing the number of people in non-traditional occupations

has been seen as a way to develop a more equal society.

There are few girls in technical and science-related occupations,

but more qualified personnel are needed

Pupils’ opinions or benchmarking?

Two surveys:

• Reasons to choose

• Interest in context

Predictors for the choice of scienceFuture relevance (future studies or occupation)

Interest in the contents of science subjects

Interest in a context where certain science domain is met

Interest in an activity type of students or method of

studying subject or teaching methods used

Achievement

Difficulty and appreciation of the topic

Research questions

1. How interested are pupils in studying physics in this

context?

2. How do boys’ and girls’ interests to study physics differ

in this context?

Methods for questions 1 and 2

• Survey, Finnish secondary schools, 3626 pupils, age

15,

• Pupils were asked to state: “How interested are you in

learning about the following?” Items were four-scaled

from not interested to very interested. Altogether, there

were 35 items probing interest.

Contexts• Ideal science context: “Linear and circular motion caused by forces”

• Science and technology in society context: “Traffic safety (acceleration and braking)”

• Technical application context: “Forces acting in bridges, and building and planning of structures”

• Human being context: “Forces acting in muscles when using them in sports”

• Investigation context: “Studying linear and circular motion and how they are caused by different forces”

• Technology, design and construction context: “Making a mechanical toy, like a balancing object”

Context sum variable

If a respondent stated not interested for every context item,

he or she gave the sum variable score 1, and if a

respondent stated very interested in every item, he or

she gave the sum variable score 4

Discussion

• Girls responded very sensitively to a change of context

• Textbooks: ideal “bodies” moving, warming up, or absorbing radiation. Textbook examples are typically technical applications

• Boys found technical application most interesting context largest gender difference

• Girls found human being most interestin context no gender difference

IMPLICATION FOR TEACHING

the measurement of physiological processes of the human body

with technical applications

Research questions

3. How important the reason to reject or choose physic is?

4. How do boys’ and girls’ opinions of importance differ in

this reason?

Methods for questions 3 and 4

Survey, Finnish upper secondary school students (N=

2934), age 17

Students were asked to answer questions for rejecters’ or

for choosers’ items.

Items were five-scaled from not important reason to very

important reason.

Altogether, there were 16 items probing choosing and 19

items probing rejecting physics.

Reasons to reject physics, examples of items• ”My future studies do not require physics”

• ”I am not competent in physics”

• ”Content in physic is too masculine”

• ”Negative message from media”

• ”Mother or another female relative have negative opinion” about physics studies”

reasons to choose physics, examples of items• ”Physics is useful in my future occupation”

• ”Physics is interesting subject”

• ”I am talented in physics”

• ”Positive attitude of my friends (e.g. my friend choose too)”

• ”Physics teacher supported to choose”

Discussion 2

• Role of parents, counselling, media etc. are viewed

small

• Small gender differences, especially in group of

choosers

• Future relevance most important reason

• Reasoning or justifying choises…

IMPLICATIONSInforming pupils about future relevance

Help pupils to be aware of actors influencing their choices
