Abstract

This study analyzes the learning loss of first-year students' chemistry concepts at FKIP, University of Mataram. The research sample was 112 first-year students taking introductory chemistry courses at FKIP University of Mataram, 14 male students (12.5%) and 98 female students (87.5%)—these students, as a whole, face two years of online learning in high school. The primary data in this study is the analysis of respondents' test results related to prior knowledge of chemistry concepts during one semester of lectures. The results showed that the idea of limiting reagents and percent composition showed the highest learning loss (53.57%), while the concept of moles and molar mass and matter showed the lowest learning loss percentage of 32.14%. Furthermore, the results of statistical tests show the relationship between the average score before the UTS implementation and after the UAS implementation. The previous lack of online learning to strengthen students' prior knowledge indicates the cause of learning loss in chemical concepts. Questionnaire analysis stated that education through WA groups, the duration of chemistry learning was low, and the lack of feedback given by teachers on assignments students were working on during the learning process strengthened the current conditions.

Abstract

The Organic Compound Mechanism and Synthesis Lecture (MSSO) is one of the important courses in the chemistry education study program, which discusses the process of forming organic compounds through various chemical reaction. The limited learning media used, which is only in the form of textbooks, also causes the learning process to be less interesting. Therefore, an interesting and easy to understand learning media innovation is needed. This research aims to develop a reading supplement in te form of a chemical magazine with formaldehyde condensation content as supporting media for MSSO lectures, as well as to determine the level of validity and feasibility. The research methode used is research and development (R&D) with a 4D (define, design, develop, disseminate) model. The result of the validation of the chemical magazine by 3 (three) validators showed a validity coefficient value of 0,93 with a very valid category, and a reliability value of 95%. Student responses to chemistry magazines showed a very practical category with a score 84.98%..
