Abstract ▼ AI-Helper

We analyzed and compared factors such as changes in the degree of difficulty of concepts presented in Chemistry I textbook, changes in class types (non-face-to-face, face-to-face), etc. on academic achievement by level (upper, middle, and lower). Students from A high school in Gyeongsangnam-do were selected for the subjects of the study. As a result of analyzing the change in the degree of difficulty of concepts, the total score of chemistry I combined by non-face-to-face and face-to-face classes during the second semester was lower than that of the first semester. As a result of analyzing the impact of factors such as changes in conceptual difficulty, changes in class types, etc. on academic achievement by level, students' grades at the 'lower level' by non-face-to-face classes were lower than those by face-to-face classes. In particular, at the lower level of the second semester, there was a large difference in grades between non-face-to-face and face-to-face classes. In the results of these studies, it was found that instructors' active feedback is important to identify difficulties in understanding learning contents for students with low levels of academic achievement and improve them at the same time.

그림 Figure 1. The combined grades by non-face-to-face and face-to-face classes were analyzed by semester and presented in 1(A). The grades by non-face-to-face and face-to-face classes were analyzed by semester and presented in 1(B) and 1(C), respectively.
그림 Figure 2. The average score of chemistry I by non-face-to-face and face-to-face classes is presented in 2(A). For each semester, the average results of non-face-to-face classes and face-to-face classes were presented in 2(B) and 2(C), respectively.
그림 Figure 3. During the first semester, the lowest and highest scores by non-face-to-face and face-to-face classes were presented in 3(A) and 3(B), respectively. During the second semester, the lowest and highest scores by non-face-to-face and face-to-face classes were presented in 3(C) and 3(D), respectively.
그림 Figure 4. By level, the average results of chemistry I by non-face-to-face and face-to-face classes was presented in (4-A). During the first and second semesters, distributions by level of average grades by non-face-to-face and face-to-face classes are presented in (4-B) and (4-C), respectively.
