Using SPRT+ to Reduce Measure Time on Student Learning Efficiency by Pre-defined Student's Confidence Indicator

摘要

In traditional teaching method in course, teachers usually used test to measure students learning efficiency, but we doing lots of test that may lower student learning motivation, so our research main purpose is how to reduce the time in test that student take and measure student's learning efficiency precisely. Some researcher combine test question with confidence indicator to make student assess their confidence about the answer and get reflection so that student can think deep about the course. Another researcher point out we can use mastery of the course to reduce test time student took. No matter to use confidence indicator or mastery of the course to reduce the test time, there is no research on both of them, so our research combine sequential probability ratio test(SPRT) and confidence indicator called SPRT+ to achieve real-time assessing student's learning efficiency. Because of students assess their own learning confidence may not be very accuracy. In our research, we pre-defined student's confidence indicator base on student's mid-term score and let student finish the test, after the test we discuss if we let student finish the same test by choice their own confidence indicator, can pre-defined student's confidence indicator make the same result in measure student's learning efficiency and reduce the test time. Result shows that we can use SPRT+(pre-defined student's confidence indicator or not) to measure student's learning efficiency and reduce the test time.
