Abstract

The purpose of this study was to design scaffolding that is connected to an ICT system (e-scaffolding) which was implemented with blended learning to improve students’ physics problem solving skills (PSS). The research method used is Borg & Gall research method and the effectiveness test used is T-test in analyzing whether there are differences physics PSS in the experimental and control classes. This article describes scaffolding systems that focus in procedural types which using prompt questions and facts found during the implementation of this product. The results showed that the developed e-scaffolding was appropriate to be used for several examinations after being evaluated by experts and practitioners. In a limited implementation, e-scaffolding has proven not to be out of the social constructivist scope and adapted to the actual abilities of students. At effectiveness test, e-scaffolding is able to connect between students in solving problems both in synchronous and asynchronous collaboration. In addition, e-scaffolding is able to split problem categories that students are experts and beginners, giving shape to performance and increasing students’ physics PSS. So, it can be concluded that e-scaffolding has been successfully developed. Suggestions for further research have been presented in this article.

Abstract

This study offers fresh perspectives on the difficulties students encounter when grasping concepts related to vibrations and waves. It highlights the need for creating more effective Higher Order Thinking Skills (HOTS) questions to enhance student comprehension.This research aims to examining the understanding of junior high school students about vibrations and waves regarding HOTS questions. The method used in this study is descriptive analysis in which 68 students of 9th grade junior high school participated and answered five multiple-choice HOTS questions about vibration and waves topic. The reliability of the questions used in this study was 0.845, indicating a high level of reliability. The results of the study showed that overall, 66% of students understand the concept of vibrations and wave, but 21% of students were categorized as very less at understanding HOTS questions related to vibration and waves well. In addition, students’ ability in understanding question with indicator C6 was also the lowest when compared to indicator C5 and C4. It was concluded that a wide deficit exists among them regarding the higher conceptual knowledge of physics. Such findings could be a starting point for making necessary adjustments in curriculum and teaching methodology at junior high school physics.
