Students in one of mr. kirk’s classes participate in new interactive history learning modules. students in another class learn history using the traditional lecture method. after three months, all students take a test to assess their knowledge of history. what kind of design did mr. kirk use?
- nonequivalent control group posttest-only design
- nonequivalent control group pretest-posttest design
- multiple-group time-series design
- single-group time-series design

The correct answer is the nonequivalent control group posttest-only design.

Explanation:

The nonequivalent control group posttest-only design is a semi-scientific way to measure a variable. The marks of the nonequivalent control group posttest-only design are the existence of two groups where only one receives a determinate treatment and both are submitted to the same variable at the end of a given period.

Mr, Kirk had two groups, one in which he applied different treatments and another in which he did not. Later both groups took the same test so they were exposed to the same variable (the test).

Since there was not a test at the beginning of the study, only at the end, it is not nonequivalent control group pretest-posttest design.

Multiple-group time-series design would require systemic testing of the groups. And single-group time-series design doesn't use a control group.
