Abstract

The Problem-Based Learning (PBL) model provides opportunities for students to develop critical thinking and higher-order thinking skills in solving problems. However, in the pre-cycle stage, students’ cognitive learning outcomes on geometric optics material were still low. This classroom action research aimed to improve students’ cognitive learning outcomes through the implementation of PBL combined with Thinking Maps and digital reading materials on the topic of optical instruments. The subjects were 35 eleventh-grade students at a senior high school in Palangka Raya City. The study was conducted in two cycles consisting of planning, implementation, observation, and reflection stages. The results showed an increase in classical mastery from 71.42% with an average score of 74.74 in the first cycle to 80% with an average score of 77.82 in the second cycle, which met the success indicators as more than 75% of students achieved learning mastery and the class average exceeded the minimum mastery criterion. The implementation of PBL assisted by Thinking Maps and digital reading materials effectively helped students gain a deeper understanding of optical instrument concepts. This finding provides practical contributions for teachers in optimizing PBL strategies integrated with visual thinking tools and digital learning resources to improve physics learning outcomes.

Abstract

Science learning in the 21st Century needs to adapt to technological developments in the Era of Revolution 4.0. 21st Century science learning uses digital technology, namely Augmented Reality combined with an inquiry learning model on the Solar System material. The research aims to determine the feasibility of the Inquiry-based Solar System Augmented Reality (SSAR) Learning Media being developed. Inquiry-based SSAR Learning Media Research is development research that uses the ADDIE Development Model with assessment by 8 validators using a 1-5 Likert scale. Inquiry-based SSAR learning media which was developed through the Analysis, Design and Development stages. The Analysis stage is carried out through an initial preliminary study to determine needs analysis. The results of the needs analysis are used in the design stage and then realized in the Development stage. The Media Development stage carried out a feasibility test through validation by 8 experts. The feasibility of SSAR Learning Media is reviewed including Media, Material, Learning and linguistic aspects. The results of the assessment by the Validator were analyzed using the Aiken formula with validation criteria > 0.75. Inquiry-based SSAR Learning Media indicators based on Aiken Validation analysis obtained validation results with a score of 0.85 > 0.75 indicating that Inquiry-based SSAR Learning Media is suitable for use in the science learning process on Solar System material
