A small group of teachers is investigating the effectiveness of an intervention to improve critical thinking of students. They employ the intervention and data are collected on the students’ critical thinking skills. The small group of teachers, principal, and assistant principals uses the results to decide whether to continue the intervention or not throughout the school. The results are shared with other teachers in the school. Is this an example of research or evaluation? Why?
