Abstract

This study aims to analyse the effectiveness of science applications in contextual learning in improving students' science literacy. This study uses a quantitative approach with a single group pretest and posttest design on eighth grade students of junior high schools in urban areas. Data were collected through science literacy tests based on literacy competency indicators, learning implementation observation sheets, and documentation. Data analysis techniques were performed using descriptive analysis, calculation of learning outcome improvement, and mean difference tests. The results showed that the application of science-based contextual learning was able to significantly optimise students' science literacy, especially in the competencies of explaining scientific phenomena, designing and evaluating scientific investigations, and interpreting scientific data and evidence. Learning that integrates real-life contexts, local knowledge, and problem solving has been proven to make the learning process more meaningful and optimise student engagement. These findings indicate that science application-based contextual learning is effective as a strategy for improving science literacy in science learning.

Abstract

This study originated from the lack of enthusiasm of students following the learning of milling machining in the classroom, because of the many distractions that make it difficult for students to concentrate. The purpose of this study is to determine whether there is a difference in students' learning concentration in the subject of milling machining techniques of vocational high school students when they are taught with whiteboard animation media and textbooks. This research design is a quasi-experiment with post-test only. Based on the researcher's consideration and initial interviews, the subjects of this study were formulated as two classes. The number of students for the experimental class XI TPM 1 (15 people) and the conventional class XI TPM 2 (15 people). The experimental class XI TPM 1 was given whiteboard animation learning media, while the conventional class XI TPM 2 was given conventional learning. To analyze the research data, t-test technique was used. The results of the t-test analysis showed that, compared to the conventional learning method, students learned milling machining techniques with higher concentration.
