The final step of the Action phase is to look at the effects of the Action Research plan by possibly using a posttest or formal assessment, student interviews, student portfolios or reviewing video footage.
A posttest, which may be the same test as the pretest, is used to measure gains in student knowledge after the implementation process. Student interviews can be used to determine if the student has mastered course or unit objectives. Student portfolios are an electronic or paper collection of student work samples used for evaluation.
Finally, the teacher can review videotape footage as a means of self assessment to determine whether or not the plan was effective and to determine where improvements can be made.
