Abstract

A study has been conducted on the development of learning media based on reels and instagram stories on the main material of Electrolyte and Non-Electrolyte Solutions. The purpose of this study. 1). To determine the feasibility of the Instagram application as a learning media on the material of Electrolyte and Non-Electrolyte Solutions at SMA Negeri 1 Wawotobi. 2). To determine student responses to the Instagram application that has been developed as a learning media on the material of Electrolyte and Non-Electrolyte Solutions at SMA Negeri 1 Wawotobi. This type of research is Research & Development (R&D) using the ADDIE development model. The instruments used are assessment/validation sheets (materials and media), teacher responses and student responses. The research sample was 15 grade XI students. The results of this study indicate that: (1) Learning Media Based on Reels and Instagram Stories have gone through the expert validation test stage with an average overall score of 87.74% (2) The student response questionnaire received a positive response with a percentage of 82.77%. From the results of this study, it can be concluded that the Instagram application that has been developed as a learning media that has been developed has very good feasibility and high practicality so that it can be used as a support in chemistry learning activities on the material of Electrolyte and Non-Electrolyte Solutions.

Abstract

Research has been conducted on the effectiveness of Problem Based Learning model on the learning outcomes of Class XI students of SMAN 3 Sampolawa on reaction rate material. This study aims to determine the effectiveness of Problem Based Learning model on student learning outcomes on reaction rate material. The subjects in this study were 25 students of class XI MIPA 1. This type of research is pre-experiment with One Group Pretest-Posttest design. The research instruments included a learning outcome test consisting of 20 multiple choice questions and an observation sheet. The results showed that the average pretest score of 29.6 increased to 77.2 in the posttest. The effectiveness of learning based on the N-Gain value of 0.68 is included in the medium category, so the Problem Based Learning model is declared effective in improving student learning outcomes. Students' responses to the learning model were classified as very good, while the implementation of learning by teachers and students was considered good and experienced an increase.
