The goals of this course are to learn data collection, design, and analysis methodologies that are particularly useful for scientific research in education. The course will be organized in modules addressing particular topics including overview of methods, cognitive task analysis, qualitative methods, protocol and discourse analysis, and educational data mining and log analysis. A key goal is to help students think about and learn how to apply these methods to their own research programs.
To enroll you must have taken 85-738, "Educational Goals, Instruction, and Assessment" or get the permission of the instruction.
Textbook and Readings
"The Research Methods Knowledge Base: 3rd edition" by William M.K. Trochim and James P. Donnelly. You can find it at www.atomicdogpublishing.com/BookDetails.asp?BookEditionID=160
Other readings will be assigned in class.
We will be using Google Wave for course reading reports and discussions. Google Wave combines discussion boards, instant messengers, and wikis into a single system. You can use it just as you would a discussion board, but you can also edit your own / other peoples' posts, play back the changes, and see changes update in real-time. Further details and account invitations will be discussed in class.
Reading reports consist of three parts: students are required to submit at least one original post per reading assignment, at least one reply or comment on another student's post, and at least one substantive addition to the reading assignment summary. More posts, replies, and summary improvements are encouraged.
|Original Post (Tuesday Reading)|| Reply (Tuesday Reading)
Summary Edits (Tuesday Reading)

Summary Edits (Thursday Reading)
|Reply (Thursday Reading)|
Posts and Replies
Original posts should contain at least one of the following:
- a question you had about the reading or something important you did not understand
- an idea inspired by the reading
- an interesting connection with something you learned or did previously in this or another course, or in other professional work or research
For readings due on a Tuesday, the original post must be submitted by Monday morning.
For readings due on a Thursday, the original post must be submitted by Thursday morning.
Replies must be:
- an on-topic, relevant response, clarification, or further comment on another student’s post
For readings due on a Tuesday, at least one reply must be submitted by Tuesday morning.
For readings due on a Thursday, at least one reply must be submitted by Sunday morning.
This means that replies for Tuesday readings are due before class, whereas replies for Thursday readings are due after. Please use this extra time to have a full and meaningful discussion on the topics discussed.
For each reading assignment, one student will be responsible for a finished summary of that assignment and its related discussion.
Each summary will consist of:
- A brief overview of the reading assignment. For a chapter from the textbook, this should be a couple sentences on major topics addressed in the chapter. For a research paper, this should be a couple sentences covering the research question(s) and primary result(s).
- A brief discussion of the methodology. For a chapter from the textbook, this should be a more detailed discussion of the main research methodology discussed. For a research paper, this should be a couple sentences discussing aspects of the data, such as the subject population or analytical methods.
- A listing of major issues or suggestions for the paper, as related to the course. Threats to validity and problems with test reliability are example topics, as well as suggestions on how to avoid or resolve such issues.
The first two parts of the summary should be complete by the morning of the day of class.
There will be assignments associated with each section of the course. Grades will be determined by your performance on these assignments, by your participation in Reading Reports, and by your participation in class.
- Course work
- 10% Reading reports
- 50% Homework assignments
- Project & final paper
- 40% Design a new study based on one (or more) of these methods that pushes your own research in a new direction.
- Apply a method from the class to your research. You should not choose a method that you have a large amount of experience with, but you may choose a method that you were planning to use for some upcoming project anyway.
- Think of it as writing a grant proposal, and remember it could actually form part of a grant if you so choose. Because some methods will be introduced after the project proposal date, we are open to a modification in your project to apply the newly introduced method. But, please check with us to get feedback and approval on a proposed change.
- No more than 10 double-spaced pages -- Be efficient. Space is always limited in academic publications and you will find it useful to learn to include only what is important. Since this is styled as a grant proposal, please beginning with a bit of literature review and discussion of significance of the area you want to investigate. You should also briefly detail plans for participants, explain specifically how you will apply the method, and describe how you will analyze the data. Certainly you will want to account for any challenges to validity that seem plausible as part of your design and writeup.
- Final Project Milestones
- March 5 - a paragraph project proposal in email
- March 15 - approval of proposed project
- April 20 - turn in a draft for feedback
- April 26 - feedback provided by April 26
- Desired: set up a meeting with one of the faculty to discuss draft
- May 5 - final paper due

Psychometrics, reliability, Item Response Theory (Junker, Koedinger)
1. From Trochim:
A. Chapter 3 - the vocabulary of measurement B. Chapter 5 - on constructing scales (it's ok to focus on the material up through sect 5.2a; the rest is more of a skim [but I'd be happy to talk about that in class also])
2. On item response theory (IRT), a set of statistical models that are used to construct scales and to derive scores from them, especially in education and psychological research:
A. Harris Article (PDF) Please take and self-score the test at the end of this article. Count each part of question one as one point, and each of the remaining three questions as one point (no partial credit!). Bring your 8 scores to class. E.g. if you missed 1(c) and (d), and you also missed question 4, then you would bring to class the following scores: 1 1 0 0 1 1 1 0 If you missed 1(a) and (b) and question 2, bring the following scores: 0 0 1 1 1 0 1 1 (note that the total score is 5 in both cases, but the pattern of rights and wrongs differs; it is the pattern that we are interested in). B. Please browse *online* through pp 1-23 of the pdf at . The math is a bit heavy going but there are links to apps that illustrate various points in the harris article. So skim the math and play with the apps.
We will discuss on Tue whatever of this we can get through, and continue the discussion as needed on Thursday. There will be additional readings for Thu to introduce fitting and using IRT models.
1. Short introduction to R (Rintro.pdf)
Please download and install R for your computer (windows, mac or linux) from . Then try all the things in sections 1-9 of this handout (section 10 is optional). You can try most things by copying from the pdf and pasting into the R command window. You do not have to be completely done with this by the time we meet for lecture 2, but you should aim to finish it soon afterwards.
2. "Cognitive Assessment Models with Few Assumptions..." by Junker & Sijtsma (Junker, Sijtsma (PDF))
Please read up through p 266 only. The math is a bit heavy going so please try to read around it to see what the point of the article is. We will try to look at some of the data in the article as examples in lecture 2.
3. "Psychometric Principles in Student Assessment" by Mislevy et al (Mislevy (PDF))
Read through p 18. This is a more modern modern look at some of the same issues that are addressed in Trochim's chapters. The remainder of this paper surveys various probabilistic models for the "measurement model" portion of Mislevy's framework (Figure 1). It is quite interesting but we will not pursue it.
