Game-based learning has emerged as a promising approach to enhance students' engagement and understanding in educational settings. This study investigates the effectiveness of integrating physics education technology (PhET) simulations as game-based learning tools in teaching physics concepts related tao equilibrium system. A quasi-experimental…

Technology has an essential role in the educational field. Technology-based mobile has the potential to improve education through Augmented Reality (AR). This study investigates the effect of mobile augmented reality on physics learning achievement and students' opinions on using this technology. The study used a convergent parallel pattern from…

The study aims to develop teaching materials in the form of LKPD on ecology and biodiversity by using valid and practical trigger questions and to determine their effectiveness in increasing student motivation and learning outcomes. This research is a development research that uses the ADDIE development model which consists of five stages, namely:…

This study aims to reveal the profile of open-start problem-solving with ethnomathematics regarding student learning styles. This research is a qualitative research study on 3 out of 31 students of Junior High School of 3 Magetan taken by purposive sampling. The three students carried out four stages: understanding the problem, planning…

Educational online games and educational videos are classroom methods that incorporate multimedia into language teaching. Previous studies have suggested that the use of online games and educational videos in language learning enhances student performance. However, no studies have been done using three different groups to examine whether online…

The pandemic has affected many aspects of our lives including education and that has caused the Government to provide alternative teaching methods and make recommendations for online learning.

This study aims to identify seventh-grade students' conceptions regarding climate change, global warming, and the greenhouse effect. The research was conducted at four local secondary schools in the Special Region of Yogyakarta,…

Students' difficulties in algebra are generally caused by the use of algebraic notation, the meaning of letters, as well as the types of relationships or methods used. Therefore, interpreting letters in algebra is one of the critical points in the transition from arithmetic to algebra. However, many students have misconceptions in interpreting…

This study aims to describe the 3D model's online modules effectiveness in the practicing mastery of conceptual knowledge in solar system learning using an instrument which tested 58 7th-grade respondents from one of the junior high schools in Jombang, East Java, Indonesia. The respondents were then divided without randomization into 29…
