Question 1

A teacher, as part of an action research project, introduces a new peer-tutoring system to improve student comprehension in science. After implementing this system for two weeks, what should be the *teacher's most critical next step* in the action research cycle?

Accepted Answer

C. Systematically collecting data on student comprehension and engagement with the new peer-tutoring system. — Following the 'Act' phase (implementing the new system), the most critical next step is the 'Observe' phase.
