Abstract

Abstract. The purpose of this study was to determine the effectiveness of the problem-based learning model based on ethnoscience on students' critical thinking skills on colloidal material. Experiments were conducted on a sample of 36 experimental class students with an ethnoscience-based problem-based learning model and 36 experimental class students with a convention learning model. This research method is a quasi-experimental design with a nonequivalent control group design. The instruments used are essay tests and observation sheets. The results of this study indicate that the average posttest in the experimental class is 76.08, which is higher than the control class, which is 69.33. These results indicate that the use of ethnoscience-based learning problem-based learning models on colloidal material is effective in improving students' critical thinking skills compared to using conventional models.

Abstract

Abstract: This study aims to produce interactive learning media based on augmented reality technology on the concept of chemical bonds and determine student responses to the media. The research method used is the R & D method. The instruments used are material expert validation sheets, media expert validation sheets, and student response questionnaires. The data obtained were analyzed descriptively. Based on the results of material expert validation, an average of 80.41% (feasible category) was obtained and the media expert validation results obtained an average of 90.92% (very feasible category). The results of the limited trial received positive responses from students with details of the percentages obtained, namely 85.75% for the usability aspect, 81.80% for the illustration use aspect, 74.57% for the future impact aspect. 79.64% for the aspect of material usefulness, and 77.20% for the grammatical aspect. Overall, the augmented reality interactive learning media developed received a positive response from students with a percentage of 79.78% and suitable for use in learning.

Abstract

The COVID-19 pandemic has changed the learning system in Indonesia to online-based learning. Students' perceptions need to be known to understand how students perceive online chemistry learning, especially during the pandemic. A quantitative method is conducted using a Likert-scale questionnaire of 25 items. The questionnaire is trying to explore students’ perceptions on three dimensions, namely, material and teaching method, learning atmosphere and environment, and social interactions. Respondents are 385 students of the science program at two public schools in Ciamis regency. The results showed that in general, the majority of students (>50%) perceive online chemistry learning positively, especially with regard to material and teaching method and learning atmosphere and environment. However, the dimension of social interaction is found to have more negative responses (>80%) than positive ones. This is apparent in the communication and interaction between students and their teachers and peers. From this study, it is concluded that while online learning seems to be relatively accepted and prepared by students, the social interactions of students need to be seriously considered as they may affect students’ mental health and well-being. Further research is therefore recommended to explore more the extent to which mental health and well-being influence students’ performance in online learning.
