Abstract

Lack of understanding of students' concepts of science material. This study aims to improve students' conceptual understanding using multimedia based on local wisdom of the keris. This type of research is a quasi-experimental design using a nonequivalent control group design technique. The population in this study were class VII students, which were divided into experimental class and control class. The data collection instrument was in the form of a concept understanding test. The data analysis technique used independent sample t-test analysis. The results showed that there were differences in the effectiveness between M-Keris and conventional Multimedia on understanding the concepts of class VII students. Based on the results of the analysis which shows the value of Sig. (2-tailed) in the independent sample t test was 0.018 < 0.05. The role of multimedia elements contained in M-Keris is an important factor to build interest in learning and students' understanding of the concepts presented. Therefore, learning with M-Keris is more effective and makes it easier for students to understand the concepts given compared to other conventional multimedia. In addition, with M-Keris, the teacher's function will be fully as a facilitator who directs and helps students explain things that have not been understood. The implication of this research is that teachers are expected to be able to use M-keris in the learning process. So as to improve student learning outcomes.

Abstract

Based on the needs analysis, it is indicated that students’ chemical literacy and scientific attitudes at SMA Negeri 1 Bayung Lencir remain low. The cause was the limited availability of chemistry learning resources that are contextualized to real life. Therefore, this study aimed to know the characteristics, feasibility, and practicality of developing student worksheet products based on Socio-Scientific Issues (SSI) on the chemical bond topic and its influence on students’ chemical literacy and scientific attitudes. The type of this study is Research and Development (R&D) with the 4D development model by Thiagarajan. In the Define stage, a needs analysis was conducted; in the Design stage, the initial design of the worksheets was created; in the Develop stage, SSI-based student worksheets were produced after undergoing validation; and in the Disseminate stage, the SSI-based student worksheets were distributed to a class of X students at SMA Negeri 1 Bayung Lencir. The results showed that the student worksheet was produced in printed form, was feasible for use, practical, and there was a significant difference in students’ chemical literacy. However, no significant difference was observed in students’ scientific attitudes. Further research is recommended to develop SSI-based worksheets for other abstract chemistry topics and to explore their influence on students' scientific attitude.

Abstract

This study aims to apply the Discovery Learning learning model based on Blended Learning to students' chemistry learning activities and outcomes. This research was conducted at SMA Negeri 5 Bengkulu City using the Classroom Action Research method. The implementation is carried out to find out problems in the learning process and steps that teachers can use to improve the quality of learning during the COVID-19 pandemic. The data collection technique in this study was a observation, interview, and test. The research shows that the activity and student learning outcomes increased, where the results of the proportion of student activity, teacher activity and the average student learning outcomes increased from cycle I to cycle II. Therefore, it can be concluded that the use of Discovery learning model based on blended learning can increase students' chemistry learning activities and results

Abstract

This research aims to analyze whether there are significant differences in problem-solving abilities and scientific attitudes between students who use the ethnoscience-based creative problem-solving learning model and students who use the Discovery learning model on colloidal materials. This research was conducted at SMA N 6 Yogyakarta and SMA N 11 Yogyakarta using a quasi-experimental method with data analysis techniques using MANOVA. Data collection techniques in this research are observation, interviews, questionnaires, and tests. The results showed that there were significant differences in problem-solving abilities and scientific attitudes between experimental class and control class students, with a significance of 0.00 < 0.05 and an effective contribution of 13.6% in the moderate category. Therefore, it can be concluded that the use of a creative problem-solving learning model based on ethnoscience has a significant influence on improving students' chemical problem-solving abilities and scientific attitudes towards colloidal materials.
