1. Requirements and learning activities that promote students’ abilities to practice the processes and procedures for creating and completing successful writing in their fields.

This course is a lecture-laboratory course. During the lecture hours students learn the theoretical background for the experiments they perform in the laboratory. The course has been assigned the most recent and advanced textbook on the subject matter. Several reference books are included for additional information. The laboratory activities include a total of seven experiments. Students are required to write a complete laboratory report for each experiment. Additionally, all the exams, quizzes, and homework for the class require mainly narrative or descriptive type answers. Therefore, students have many opportunities to practice writing in the field of materials science.

2. Requirements and learning activities that promote students’ abilities to understand the main features and uses of writing in their fields.

Students are required to attend the lecture hours. The reports they write include an introduction section that covers the scientific background for the experiment. This obligates students to study the theoretical background of the experiment. In the Results and Discussion sections, students are required to implement their understanding of the background theory on analysis of the data they obtained from the experiments.

3. Requirements and learning activities that promote students’ abilities to adapt their writing to the general expectations of readers in their fields.

8


Students are provided with a handout explaining the format of the reports and the details to be included in each section of the report. The format is similar to the format of a research paper in an engineering journal. Students are required to review and critique other students’ reports. This will also help students write reports based on the expectation of readers in their field. Students also have opportunities to practice writing group reports. This will give students many chances to interact with other students and group members for analyzing data and writing reports explicable for the readers in their field.

4. Requirements and learning activities that promote students’ abilities to make use of the technologies commonly used for research and writing in their fields.

The state-of-the-art equipment used for teaching some of the experiments for this course includes x-ray diffractometer, tensile, hardness, microhardness, and microscopy testing units. The students use MS Word, Excel and other software to write their findings and produce professional reports.

5. Requirements and learning activities that promote students’ abilities to learn the conventions of evidence, format, usage, and documentation in their fields.

For the laboratory reports, students are required to include: Introduction, Experimental (Materials, Equipment, and Method), Results, Discussion, and References. In their results section, they are required to analyze their data and compare their results to the related published data. In the discussion section they need to discuss the differences between their results and the published data, explain the reasons for the discrepancies, and identify the sources of error. This is an accepted technical writing method in the engineering field.

Instructor: Dr. Saeed ZiaeeOffice: 203D STTel: (507) 457- 2984E-mail: [email protected]

Office Hours: will be posted by the office and on Desire to Learn (D2L).

Teaching Assistant: TBD

OBJECTIVE:

This course is designed to teach students to operate thermal analysis instruments and to analyze their data in order to: identify polymers, determine their thermo-physical properties, investigate miscibility of polymer blends, and gain insight into morphology of polymeric systems. A major part of the course is also geared toward writing laboratory reports and assessing technical writings. This course is designed to satisfy the Writing Flag requirement.

NO TEXTBOOK IS REQUIRED. An audio book will be posted on D2L for this class. The book is an American Chemical Society short course on physical chemistry of polymers. Other than this book, any introductory book to polymer science and engineering is helpful for this class. Good authors include Leslie Howard Sperling, C.B. Bucknall, David W. Eisele, and Fred W. Billmeyer but there are many other books. The content of this course is not polymer chemistry. It is polymer physics or physical chemistry. Here are some good reference books that can give you definitions and data quickly:

1 – Physical Chemistry of Polymers, James Mark, American Chemical Society short course, 1986.

2 – Textbook of Polymer Science, Fred W. Billmeyer, Jr., 3 rd Edition, 1984, John Wiley & Sons, Inc.

COURSE EXPECTATIONS AND EVALUATION:

1. TEST (3 tests and final): Each has 10% of your final grade. Your midterm will be given during the lab hours so you have enough time to work on it. The final has to be held at its scheduled date and time. Tests are closed book and notes however, I will either allow you to bring or provide the handout of data that you might need. Materials in the exams can be from any part of the course except instruction/operation of laboratory instruments. (40% Total)

2. QUIZ: You will have oral and written quizzes, during the lab, on the operation of the instruments. You will also be quizzed on quality of outlines and lab reports written by students from previous years. Quizzes are taken individually. (10% Total)

3. LABORATORY REPORT: You have 7 laboratory experiments. Each lab report makes up 5% of your final grade. You work in groups for these labs. Follow the format and guidelines that will be given for your report. This will save you time and help you to write and read technical papers. You will do experiments in groups; each group member should know all aspects of performing experiments, analyzing data, and writing reports. Each group will submit one report but grades will be normalized based on peer review of team members. (35% Total)

4. PROJECT: One project will be assigned for the semester. This is a group project. You will use the instruments that you learned about in the course to complete the project. You will write a report also. Your final grade has contribution from your data, data analyses, deduction and reasoning, and writing the report. The breakdown of the grade for each of these parts will be decided later according to the complexity of each project. An oral quiz will determine the contribution of each group member to the completion of the project. (15% Total)

Total Score = 100 GRADE SCALE: 100 - 90% A, 90 - 80% B, 80 - 70% C, 70 - 60 % D

POLICIES

1 – Come to class and lab on time. Otherwise you may miss the quiz. Keep quiet in class and lab, especially when we are learning the operation of an instrument.

2 – If you have to miss a HW, a lab, or an exam, you should consult with me prior to being absent or immediately after you return to class. Otherwise, it is understood that you will get a grade of zero for that assignment or exam.

3 – All information used in your homework, laboratory reports, or projects that have sources other than your notes, should be properly referenced.

4 – You are required to wear safety glasses in the laboratory when working with chemicals. If a student fails to wear safety glasses, he/she will be dismissed for the day and will receive a failing grade for that lab. Those of you who wear contact lenses should be very careful around chemicals since the vapor of some solvents and curing agents may cause your lenses to swell. Do not bring any food or drink into the labs. This is for your own safety. Many of the chemicals we use do not evaporate easily so items contaminated with those chemicals can stay around for a long time. Ingestion of these chemicals can cause serious problems to your health.

15


5 – Points will be taken off if I or the grader cannot read your handwriting. Show calculations completely and answer questions as thoroughly as you can. If I cannot follow your reasoning, I cannot give you credit. You are proving to me that you know the answer.

6 – I do not agree with memorizing definitions word by word (especially someone else’s words such as mine, textbook’s, or other students’); however, you must be able to express definitions in your own words/terms. Do not worry if your definition is not as concise as that in the books or notes at first. The point is that in the process of rewording the definitions, in your terms, you understand and remember the meaning of it for a longer period of time. This practice also shows the hidden subjects/assumptions/conditions associated with a definition that you and I might have ignored. Eventually you become more thorough and concise with your answers.

TOPICS

These are the topics we will go over in class. More topics might be added or some of the following topics might be replaced by others as the project in class may require.

1. Introduction: Tg, Tm, Free Volume, Additivity Rule of Mixture, Stoichiometry, Physical Interactions, Molecular Weight and MW Distribution, Cross-link Density, structure-property relationship

In this course, students are required to write reports for their laboratory experiments and their project. They are taught to write technical reports. The reports are based on experimental data collected by the students in the lab. Students learn about various sections of a technical report and the type of information that fits into each section. This activity leads to creating a preliminary outline for a report. The outline of every report is graded and given back before the students proceed to write the full report. In writing the full report, students learn the order in which each section of the report should be written to produce a coherent and cohesive report. The reports are graded mainly based on the logical order of presentation of information and sufficient details, in addition to data analysis and interpretation. A sample outline and report are provided for the students.


In all reports and project, students are required to compare their findings to those reported in the literature and explain the cause of any discrepancy in their experimentally-obtained values. This exercise makes up a small portion of the lab reports

18


and a large portion of the project report; they do not merely write up their findings. They practice how to reason out their observations in writing.


In all laboratory reports, students are required to present materials in a coherent manner, to use consistent tense throughout the report, to write clearly and to the point, and to distinguish between explaining their observations and interpreting the data. These are some of the basic expectations in writing engineering reports that are practiced in this class.


State-of-the-art instruments are used in this course. Students are divided into groups and are required to run the instruments and analyze their data for the subsequent report. Each group is trained on operation and data analysis of each instrument. Detailed written instruction and visual tapes are provided for future references as well. There are two major activities in the lab period. For about the first half of the semester, students learn the operation of instruments using standard samples/materials. Lectures complement the theory behind the phenomena that these tests/instruments exhibit. In the second half of the course, students complete a project, in which they use all the instruments they learned to prove a technical point. They experience a research-type activity. To write reports, students use Microsoft Word, Excel, and Kaleidagraph. Kaleidagraph is plotting software and has fitting capabilities as well.


In all laboratory reports, students are required to properly reference sources they used to complete the report. This activity is even more relevant to the project.

In each topic and each week of the semester students conduct an experiment and write a complete report describing the test procedure, the analysis of results, and the conclusions of the experiment. The format of the reports is similar to technical and professional reports in engineering practice and scientific journals in the engineering field.


Students are required to follow the technical report-writing standards in the field of engineering. Each report includes a cover letter, title page, table of contents,

33


introduction, procedure, results, discussion and conclusions. These sections constitute the main features of writing in the engineering and scientific fields.


In preparing their reports, the students organize the contents and write the texts considering the standpoint of the reader. The reader is interested in the nature of the problem, the method used to attack the problem, the results obtained, and the experimenter's analysis of the results. In addition, the findings of the investigation should be clearly illustrated and defended. Usually, results are backed by similar findings in the published literature or a scientific justification is provided to explain the anomalies.


For each topic, the students are required to read the American Society of Testing and Materials (ASTM) standards and specifications, perform research on the materials to be tested, conduct the tests, and compare their results with published values in the literature. In this exercise, students use library search, engineering index data search and various Web searches. Students use state-of-the-art data acquisition systems, such as INSTRON, MTS TESTWORKS and LABVIEW, and up-to-date software to perform their analyses and write their reports. Students are also required to consult with the writing lab in Minne 340 to discuss their writing styles and edit their reports.


In each topic, students are required to discuss their findings, and address the specific questions forwarded in the assignment. If the answers do not adequately cover the important aspects of the results, these are covered in addition. The discussion is based on both the results of laboratory work and similar work reported in the literature. Attempts should be made to explain observed anomalies. Particularly worthwhile points of discussion are: accuracy and practical significance of laboratory results. A good amount of literature research is desirable in most cases. In the conclusions section, students are required to provide a summary of the major findings and the significant implications of their test results. The guidelines of the preparations of the laboratory reports are attached.

PREPARATION OF LABORATORY REPORTS

ORGANIZATION AND CONTENT

In preparing a report, the organization should be considered from the standpoint of the reader. He/she is interested in the nature of the problem, the method used to attack the problem, the results obtained, and the experimenter's analysis of the results. Therefore, the report should have the following form:

Cover Letter. Response to company requesting the test services. May include a brief summary of major findings.Title Page. This page should indicate the project, author's name, date,

and course.Table of Contents. Include titles, subtitles, appendices and page

numbers.Introduction. The nature of the project should be described briefly. Normally a few sentences will be sufficient, unless some unusual features are involved. The composite used in the test should be described in detail under this heading; this description should be based primarily on three major items: fiber classification, matrix composition, and composite type (such as prepreg, short fiber, etc.). Additional pertinent adjectives can be used, where applicable, to describe items such as: generic name, orientation, or structure.Procedure. Standard procedures already described in textbooks or class notes need not be rewritten in the report, but they may be simply referenced. However, specific test conditions should be noted, and special aspects involved in the procedure, and not covered elsewhere, should be described.Results. Only the final summary of results, usually either in tabular or graphical form, should be shown in this portion of the report. All other preliminary results should appear in an appendix. No results or computations of any type should be omitted from the appendix, except for the summary of results appearing in the report proper.Discussion. There may be specific questions concerning the project, and these should be answered carefully. If the answers do not adequately cover the important aspects of the results, these should be covered in addition. Such discussion should be based on both the results of laboratory work and similar work reported in the literature. Attempts should be made to explain observed anomalies. Particularly worthwhile points of discussion are accuracy and practical significance of laboratory results. A limited amount of literature research is desirable in most cases.Conclusions. A brief summary of the major findings and the significant implications of the test results (one paragraph, or two at the most).References. A reference list indicating all sources of information used for the report should be given. The format of the references list should be

35


consistent in itself and according to some standard style, one acceptable example of which is included with these instructions. Number the references and refer to each reference by the corresponding number or by the name of the author.Appendix (or Appendices). This portion of the report should contain all laboratory sheets, calculations, secondary results, instruction sheets, and relevant data not of sufficient importance to appear in the report proper.

GENERAL FORMNeatness. Neatness is a habit developed by conscious effort. Consequently, there is no excuse for an untidy report. Typing is required. Coordination with the Writing Lab is strictly recommended. Greater attention should be given to neatness in the more important parts of the report (e.g., Title Page, Results, etc.). The laboratory sheets, on which original readings and computations are recorded, may be submitted in their original form as an appendix to the report. An effort should be made to be neat when completing these sheets in the laboratory. It is also essential that each sheet be complete with regard to sample number, date, etc.Graphs. Graphs are frequently the most important part of the report, since they often summarize the results of the work. Therefore, a carefully considered presentation is vital. Important points to be followed in drawing graphs include the following:1. Provide a prominent and descriptive title.2. Clearly indicate coordinate scales and appropriate units.3. Where a curve is based on a formulation, show a line only; do not

show points through which the line is drawn.4. Show points corresponding to experimental data clearly and

distinctly; then, use a smooth prominent curve to indicate the trend suggested by these points.

5. The scale projections or grid lines crossing the graph should be thin lines which are insignificant in comparison to the curve indicating the results.

6. All curves should be drawn with a french curve, if necessary.7. Curves and points representing different portions of the work

should preferably be differentiated by use of different symbols or color print.

8. At least one inch of clear margin is desirable on all sides of the graph.

9. Pages which are read from the side should be placed with the bottom at the right-hand, or unbound, side.

Tables. When the results are reported in tabular form, titles and linework should be given care similar to that used for graphs. Thicker lines should separate major groupings, with thinner lines used elsewhere.
