Abstract

The ability to think creatively and learn independently of students is very important in learning mathematics. As a result, we require a learning model that can help students develop their creative thinking skills and independent learning, such as the Contextual Teaching and Learning (CTL) learning model. This study aims to determine whether the Contextual Teaching and Learning (CTL) model can improve students' creative thinking skills and independent learning. The method in this study is quantitative with the CTL model using the Class Action Research (CAR) method which was carried out in class XII IPS 1 SMA Pasundan 7 Bandung with 30 students. The technique used in data collection is quantitative data with a test instrument and qualitative data with a questionnaire instrument. The findings indicated that using the CTL learning model in mathematics can improve students' creative thinking skills and independence in class XII IPS 1 SMA Pasundan 7 Bandung. CTL model students outperform conventional learners in terms of creative thinking ability and mathematical learning independence. There is a link between students' mathematical learning independence and their ability to think creatively.

Abstract

This study aims to determine the effectiveness of the Thinking Aloud Pair Problem Solving (TAPPS) method in increasing strategic mathematics competence and independent learning for high school students compared to the discovery learning method. The experimental method obtained the TAPPS method consisting of 31 students in class X IPA 2 and 31 students in class X IPA 1 received the Discovery Learning method. Data analysis included descriptive statistics, Mann Whitney test and content analysis in the Thinking Aloud Pair Problem Solving method and a scale of attitudes towards learning independence. The results showed that students who received the TAPPS method had a better increase in strategic mathematical competence and independent learning than students who received the Discovery Learning method. The TAPPS method encourages critical thinking, creativity, and active participation in group discussions, increasing confidence in solving math problems.

Abstract

This study aims to develop and evaluate Augmented Reality (AR) integrated with GeoGebra learning media to enhance students’ conceptual understanding and learning interest in three-dimensional shapes at the junior high school level. This research employed a Research and Development (R&D) approach using the 4-D model (Define, Design, Develop, and Disseminate). The study involved 29 ninth-grade students at a state junior high school in Cilegon, Banten, Indonesia. Data were collected through validation questionnaires, student response surveys, and conceptual understanding tests (pretest–posttest). The results showed that the developed learning media achieved high validity, with scores of 85% for media validation and 82% for material validation. The practicality level was also high, with a student response score of 89.2%, indicating that the media was easy to use and engaging. In terms of effectiveness, students’ conceptual understanding improved, as indicated by an increase in the average score from 60 (pretest) to 80 (posttest), with a gain score of 0.67 (moderate category). Additionally, students’ learning interest increased from the “fair” category to the “good” category. These findings indicate that AR-GeoGebra-based learning media has the potential to improve students’ conceptual understanding and learning interest in three-dimensional shapes. However, the results should be interpreted cautiously due to the limited sample size and the absence of inferential statistical testing. Therefore, further studies with larger samples and more rigorous analysis are recommended.
