Project Design and Data Collection Methods: A quick and dirty introduction to classroom research Margaret Waterman September 21, 2005 SoTL Fellows 2005-2006
2
Where are we in the Action Research Cycle? Identify Innovation Gather Data Analyze Data Interpret Data Develop Action Plan ☻ Decide when and how to collect data
3
Design vs. Method Design is about when and from whom you are going to collect data so that the data can be interpreted. On Tuesday With Colonel Mustard Methods are about where and how you are going to collect that data. In the Library With a candlestick With an interview
4
Designs: Experimental Experimental: strongest for drawing inferences about cause and effect. Control vs. experimental groups, randomly assigned, one variable at a time Diagram as follows: O 1 X 1 O 2 O 1 O 2 O = observation, X = treatment; Each row is a group
5
Experimental designs Problems: Not always possible in education to have two or more matched groups, Random assignment usually not feasible, May not be suitable for small-scale projects Usually not for classroom research problems
6
Designs: Pre-Experimental Weakest designs: Post test only X 1 O 1 Slightly stronger: Post-test with comparison group X 1 O 1 O 1 NOT RECOMMENDED
7
Pre-Experimental: Post Test Only Problems: Too many other reasons for observed conditions Cannot draw valid inferences about causality because you don’t know what pre-treatment condition is. In comparison group: may have differences in incoming ability in the two groups Good for: preliminary observation and development of hypotheses, not showing cause and effect
8
Designs: Pre-Experimental One group, Pre-test Post-test O 1 X 1 O 2 Uses: Can make some inferences about cause and effect, but only when discuss possible intervening variables. Useful in classrooms when trying new techniques or materials.
9
Pre-Experimental: Pre-test, Post-test Problems: Can’t discount all intervening variables: e.g., history, awareness of being in an experiment, selection effects on group membership. Generalizability is limited May sensitize students with the pre-test
10
Designs: Quasi-Experimental Uses an experimental design, but groups are not randomly assigned. O 1 X 1 O 2 O 1 O 2 Effect of treatment isolated X 1 O 2 Use two more groups to O 2 isolate effect of pre-test. Can make inferences with more confidence than with one-group designs Problem: intervening variables again.
11
Design: Time Series One group, multiple observations before and after treatment. Can be two groups or two treatments. O 1 O 2 O 3 O 4 X 1 O 5 O 6 O 7 O 8 OR O 1 O 2 O 3 O 4 X 1 O 5 O 6 O 7 X 2 O 8 O 9 O 10 Look for BIG differences after treatment as compared to before treatment. Problem: The intervening variables
12
Linking Design and Methods O 1 X 1 O 2 Suppose the design is one-group, pre- test, post-test: How, where, and exactly when will the data be gathered at the two points of observation?
13
Action Research Often Uses These Kinds of Methods to Gather Data Surveys Observations Interviews Artifact Analysis
14
Methods of Gathering Data Make observations Structured observations Unstructured observations Ask questions Surveys Interviews Examine and Score Artifacts Tests, portfolios, treatment plans, student comments Must design scoring guide
15
Structured Observations Examples: Use a class map to keep track of who asks questions, answers questions, makes comments. Have a list of behaviors. Make simple hash marks for each type of behavior when it occurs. Make a list, from a recorded class discussion, of the kinds of questions you asked.
16
Methods: Unstructured Observations Examples A journal that a teacher keeps to record personal impressions of how a class is going. A written remembrance of interactions with one or a few students that are being tracked over time. A written set of impressions made while watching a videotape of a class.
17
Methods: Unstructured Observations Think of these as similar to ethnographic “field notes,” a place to record reactions, impressions, planned actions, responses and thoughts. Can be useful to see trends in how YOU are responding to the innovation you are attempting. Can be useful when studying one or a few students, again, over time to see trends.

Methods of Gathering Data Make observations Structured observations Unstructured observations Ask questions Surveys Interviews Examine and Score Artifacts Tests, portfolios, treatment plans, student comments Must design scoring guide
19
Methods: Questioning (survey/interview) Uses a prepared set of questions. May have open-ended or close-ended questions, or a combination. Good for getting background info. Can be used pre and post treatment. Can address things that may not be visible, such as attitudes, motivation. Use with individuals or groups.
20
Methods: Questioning with Surveys Examples: A survey of attitudes toward science Rankings of importance Student ratings of instruction May include open-ended questions, e.g., what element of this course most helped you to learn? May include some content, but if entirely content, it’s a test and is an artifact of the course.
21
Sample from an Survey
22
Methods: Questioning with Interviews Advantage over surveys: can ask follow-ups, more personal contact. Examples: Sort readings by usefulness, telling why Solve a genetics problem aloud, explaining thinking A focus group Interview of team members in small groups
23
Sample from Interview
24
Methods of Gathering Data Make observations Structured observations Unstructured observations Ask questions Surveys Interviews Examine and Score Artifacts Tests, portfolios, treatment plans, student comments Must design scoring guide
25
Method: Examine and Score Artifacts Examples of artifacts: Diagrams of cells before and after instruction Wear on computer keys to see which are hit most Answers to a test question Portfolios Term papers Case analyses Management plans Treatment plans
26
Methods: Artifact Analysis Decide what you kinds of materials you want to collect Justify why the artifact you are choosing is a good choice given your research question Create a scoring rubric (guide) to assign points Good for pre-post designs
27
A KEY TO SUCCESS: Pilot Test Your Instruments Give a small group of people (not in your class if you can) your survey or interview Collect sample artifacts to see if your grading scheme works Try out your observation scheme to see if it needs to be tweaked.
28
Designs and Methods: Summary Many of these approaches are familiar to we who teach Much of this is used in research in many disciplines. Talk about your design and instruments with Teaching Associates, Fellows, other colleagues. Keep your data collection focused. Try to keep the project reasonable for the time you have available.
29
To create your own plans answer the questions below: From whom are you gathering data? More than one class, subgroups? When will you gather data? All one term, over several courses, in three weeks? How will you gather data? Questions, artifacts, observations? Where will you gather data? Classroom, online forum, mailed survey, telephone?
