Abstract

This study aims to analyze the effectiveness of e-learning media based on learning style in the form of e-posters, podcasts, and interactive videos on students' cognitive learning outcomes. This type of research is quantitative research. This study used a sample of 32 grade X PMIA 1 SMA Negeri 3 Banjarmasin students. This research uses Google Classroom as a platform for learning activities. Learning media in the form of e-posters, podcasts, interactive videos, and student learning outcomes can be downloaded and uploaded on Google Classroom. The research instrument used is a learning style questionnaire containing 30 statements. Data analysis in this study used a normality test, and Wilcoxon signed rank test. The cognitive learning outcomes of students with visual, auditory, and kinesthetic learning styles were 90.66%, 93.33%, and 87.33%, respectively, with ­N-gain  values of 0.75, 0.80, and 0.71. Based on data analysis, the results of this study show that e-learning media based on learning style is efficacious in improving the cognitive learning outcomes of students with visual, auditory, and kinesthetic learning styles. This learning style-based e-learning media can be applied to other chemical materials or subjects. The study employed-N-gain values to analyst the learning outcomes of the students. The - N gain values for students with visual, auditory and kinesthetic learning styles were 0.75, 0,80 and 0.71 respectively.  Overall, the data suggests that the learning outcomes of the students were quite positive and that the use of various learning media and Google Classroom as a platform can be effective in enhancing students learning outcomes.

Abstract

Previous research studies found that Case-Based Method (CBM) and Project-Based Learning (PBL) models increase student motivation, critical thinking, and problem-solving. However, so far, the success of implementing these models has mostly been based on learning outcomes. Not many research studies have been carried out to reveal the effectiveness of these models by analyzing the learning process. This research is a qualitative descriptive study that aims to analyze classroom communication on solving problems in Chemistry lessons implementing the CBM and PBL models using Transcript Based Lesson Analysis (TBLA). TBLA is an analysis method based on communication occurring in the classroom. In this research, TBLA analyzes the classroom communication on solving problems in the Wood Chemistry course at the Department of Chemistry Education, Lambung Mangkurat University, Indonesia. A total of 26 students were involved. The classroom communication was recorded by camcorders and the data were transformed into transcripts.  The data was processed using Excel to produce a TBLA graph. The results show that (1) the ratio of lecturer and student communication intensity using the CBM model in the classroom is 1:3, and the PBL model is 1:1. (2) The CBM model provides a good environment for the development of student HOTS through in-depth multi-directional communication patterns in the problem-solving process. (3) PBL builds better collaboration between students compared to the CBM model. This research implies that the quality of classroom communication can be improved by integrating the HOTS questions and independent group work as implemented in the CBM and PBL models.
