correct answer rate
Two years and a half have passed since the follow-up program system (FP system) has begun, where the FP system consists of the LCT (learning check testing), the CWT (collaborative work testing), and the FCT (follow-up program testing). In this paper, we consider the CAR (correct answer rate) to each question in the LCT items, and compare the CAR in 2017 and that in 2018.
Although we have almost three years’ CAR results and we can compare among these results, we use only the cases of the results obtained in 2017 and in 2018. Because, in the first semester in 2016, the numbers of questions to analysis basic and linear algebra are six, but in the second semester, the numbers of questions are changed to be ten. In 2018, the numbers of questions are seven, and five questions are the same as used in 2017. Thus, we compare the LCT CAR results between the 2017 results and the 2018 results.
