An Investigation of the Effects of Online Test Strategy on Students' Learning Behaviors.

Online tests have been identified as a core learning activity. Unlike conventional online tests, which cannot completely reflect students' learning status, two-tier tests not only consider students' answers, but also take into account reasons for their answers. Thus, research into a two-tier test had mushroomed but few studies examined why the two-tier test approach was effective. To this end, we conducted an empirical study, where a lag sequential analysis was used to analyze behavior patterns. The results indicated students with the two-tier test demonstrated different behaviors which develop \"breadth to depth\" and \"depth to breadth\" strategies.
