The laboratory is a place to train students' skills in conducting demonstration, experimental and scientific development practices. The provision of complete laboratory tools and materials and good laboratory management will make learning chemistry run optimally, but some high schools still do not meet the standards of facilities and infrastructure in the laboratory. Therefore, the researcher tries to collect the problems and constraints in the implementation of the practicum and find alternative solutions to the problem solving based on literature review and expert opinion. This research is a qualitative study which is a case study research in several high schools in Medan. The instruments in this study were student questionnaire, teacher questionnaire, principal questionnaire and observation sheet using Likert scale analyzed using the percentage formula. the results of the analysis of case studies conducted in a number of high schools in Medan, it can be concluded that, the area of chemistry laboratories in several schools in Medan meets BSNP standards, but there are still science laboratories used for chemical laboratories. The results of the analysis of equipment and materials that support the implementation of the practicum after the presentation of X1 schools 76.36%, X2 schools 65.67% and X3 schools 87.27%.
A good learning process can be realized if it is supported by quality learning resources and learning media. So that one of the efforts that educators can do is to innovate in the development of learning resources and learning media. This study aims to produce a chemistry e-module assisted by Flip Pdf Professional as a learning media and learning resource that is suitable for use in learning non-metal chemistry on the subject of carbon and silicon. This research is a development research (R&D) with the ADDIE model. The data collection instrument used was a validation questionnaire based on the National Education Standards Agency (BSNP). Data were analyzed by qualitative descriptive and descriptive statistical analysis. The results showed the feasibility of the chemistry e-module developed with an average score of 3.61 or 90.4% and included in the "valid" criteria for use in learning
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
