Abstract
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.
Highlights
In traditional teaching method in course, teacher usually use exam to measure student’s learning efficiency, when a exam contain lot of concepts that make teacher hard to improve student’s learning efficiency, we can’t give student what they want to know, so some researcher provide using concept to measure student’s learning efficiency[1][2], that lead to another problem, if we let student take lots of test, it will lower student’s learning motivation which make us hard to measure student’s learning efficiency
Because of SPRT’s variables are set at beginning, our study change this variables according to each student the figure 3 show the equation, when student choice confidence indicator and finish test, we can use this equation to find student’s mastery of the concept
Our study subjects are from Chung Yuan Christian University students who study Operating System, there are total 161 subjects, experimental group have 85 subjects, and control group have 76 subjects, student must finish SPRT+ test and SPRT test we compare both result with Pearson Correlation, first we use SPRT+ and SPRT to test student’s learning efficiency, the result shows that SPRT+ and SPRT have no Significant in the test, Table II shows both SPRT+ and SPRT correctness about concepts
Summary
In traditional teaching method in course, teacher usually use exam to measure student’s learning efficiency, when a exam contain lot of concepts that make teacher hard to improve student’s learning efficiency, we can’t give student what they want to know, so some researcher provide using concept to measure student’s learning efficiency[1][2], that lead to another problem, if we let student take lots of test, it will lower student’s learning motivation which make us hard to measure student’s learning efficiency. We use Operating System as our experiment course because Operating System contain many important concepts student must have to take lots of time on learning and doing test, so our research’s key point is to reduce test time and measure student’s learning efficiency precisely. We use computer technology to do our experiment, Computer-Based-Instruction is common use in nowadays course [3][4]. Computer can deal huge data, so we can analysis data more many research started to explore the computer application on exam and teaching in teaching technology[5],our experiment mean purpose is use confidence indicator and mastery of the course to create a new measure way that can reduce test time student took and get student’s learning efficiency precisely, and use student’s mid-term score as their confidence indicator compare with pre-test which student choice their confidence indicator by their own
