Abstract

This research is a quantitative study that aims to find out misconceptions that occur in class X science students of SMAN 03 Bengkulu City on Stoichiometry material. The data obtained in this study were collected by means of a written test on an instrument that has been tested for validity, , reliability, difficulty index, and discriminatory power. The results of the analysis of the percentage of misconceptions that occur in the stoichiomeric material at SMAN 3 Bengkulu City are in the range of 0%-2,2%. Based on the literature, misconceptions with this number range are in the category of moderate misconceptions. The misconception with the smallest percentage value is in item number 2 with a percentage of 0,1%, namely in the sub-topic of Atomic Mass. The misconception with the most significant percentage figures occurs in questions number 9 and 10 or in the sub-chapter interconversion of moles and chemical calculations, which is 2,2%. Factors that cause misconceptions consist of internal factors caused by the students themselves, and external factors that cause environmental factors. These factors are wrong preconceptions or initial concepts, learning methods, student abilities, lack of interest and motivation to learn, wrong intuition, and inadequate books.

Abstract

This development research aims to determine the level of feasibility and student response to the developed digital LKPD. The research was carried out in June-August 2021 at Bengkulu University and SMAN 08 Padang Jaya Bengkulu Utara. The development model used in this study is the ADDIE model which consists of 5 stages, namely, Analysis, Design, Development, Implementation, and Evaluation. The sample used in this study was class XII IPA. The trial was conducted on a small scale with 12 students of class XII science. The research data was obtained from a validation questionnaire of material experts and media experts as well as student response questionnaires. From the results of the study, it was obtained that the feasibility level of digital LKPD in the material aspect was 85% with a very valid category. Meanwhile, the media aspect is 85,6% with a very valid category. The results of student responses to digital LKPD in small-scale trials obtained a percentage of 87.03% with a very interesting category. The results of this study indicate that the Digital LKPD developed is very feasible to be used in the learning process.
