1. Strategies for Effective Program Evaluations U.S. Department of Education The contents of this presentation were produced by the Coalition for Evidence-Based Policy, in partnership with the National Opinion Research Center (NORC) at the University of Chicago, under a contract with the Institute of Education Sciences.

2. Step 1: Find a researcher with expertise in conducting rigorous impact evaluations to include on the study team.  Contact authors of previous, well- designed impact evaluations.  Ask the evaluator to identify a plan that describes in non-technical language, how they would conduct the study.  Check references

3. Step 2: Decide what research question(s) the study seeks to answer.  Evaluate a specific, well-defined MSP approach.  Measure the effect of the program on teachers’ content knowledge.  Measure the impact on student knowledge.  If resources permit, ask questions about the long-term effect of the MSP projects.

4. Step 3: Decide on the study design.  Decide on overall design: preferably a randomized controlled trial, or if not possible, a well-matched comparison-group study.  Decide the sample size to measure teacher content knowledge – at least 90 teachers needed.  Decide the sample size to measure student achievement – at least 60 teachers needed.

5. Step 3 continued:  Decide how to recruit and allocate teachers.  The simplest way to allocate teachers in a RCT is to apply random assignment to the entire sample. However, if there are big differences across the group (high-achieving, low-achieving) then grouping in blocks and then random assignment.  In a comparison group study the teachers must be very closely matched: First, teachers must be closely matched by achievement levels; and second, by students’ achievement.

6. Step 3 continued:  Decide how to measure MSP project outcomes for student achievement. There are 3 conditions: --must obtain scores for individual students; --must obtain scores before they enter the teachers class, and at the end of the study; and --must be able to convert the scores so that they will enable comparisons across grade levels.  Decide how to measure teacher content knowledge.

7. Step 3 Example: Program group Control group

8. Step 4: Gain the cooperation of teachers and school officials.  Identify one or more senior-level advocates for the study.  Gain teachers’ cooperation by explaining the benefits of the research design.  Satisfy privacy (FERPA) concerns in your design.  Special consideration for matched comparison group of teachers from another school district.

9. Step 5: Allocate teachers to the program and control (or matched comparison) groups.  The evaluator should conduct random assignment of teachers rather than project director.  Ask participating teachers not to share their materials.  Ensure that students are assigned to classes using the normal procedures.

10. Step 6: Collect the data needed to measure the MSP project’s effectiveness.  Make process as short and streamlined as possible.  Provide a unique personal identifier for each participant.  At the time of assignment, obtain pre-program performance data.  Make every effort to collect data from 80 percent of the original sample of teachers.

11. Step 7: Analyze and report the study’s results.  Obtain regression-adjusted estimates of the MSP project’s effect on student achievement.  Use the students’ pre-program test score as a covariate.  Use data from all of the original participants.
