Abstract

Thinking creatively is a crucial higher-order skill that students must acquire when they graduate from university. This necessitates lecturers designing and developing learning processes that actively engage students while fostering their creative thinking abilities. This study aims to develop and validate general chemistry teaching materials on organic compounds and reactions using the PjBL-STEM model and evaluate their effectiveness in improving students' creative thinking skills. The study employed the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model. The teaching materials were designed as comprehensive books that adhered to the PjBL-STEM framework. Effectiveness was measured by analyzing improvements in students’ creative thinking abilities through quantitative testing. The results demonstrate that the PjBL-STEM-based teaching materials are valid and feasible for implementation. Their effectiveness in enhancing students' creative thinking abilities was statistically significant (t-count = 32.488; p = 0.000), with an average improvement of 42.725 ± 8.317. The development of PjBL-STEM-based teaching materials offers a valuable tool for chemistry education, effectively promoting creative thinking skills among students. This approach provides a practical framework for lecturers to design innovative, student-centered learning strategies.

Abstract

Chemistry learning on molecular shapes remains challenging due to the abstract and three-dimensional nature of the concept, while existing learning media often fail to provide interactive visualization. This study aims to develop and evaluate an Augmented Reality (AR)-based mobile learning media to improve students’ understanding of molecular geometry. The research employed a Research and Development (R&D) approach using the ADDIE model through stages of analysis, design, development, implementation, and evaluation. The developed AR media visualizes 3D molecular models that can be manipulated via smartphones. Expert validation results indicated that the media was highly feasible, while student trials showed significant improvements in learning outcomes (N-Gain = 0.65) and motivation. The findings suggest that AR technology effectively supports the comprehension of abstract chemical concepts and offers an innovative solution for technology-integrated learning in 21st-century classrooms.

Abstract

This study used a mixed qualitative and quantitative approach with 25 purposively selected students divided into two experimental classes. Experimental Class 1 learned acid-base material using Problem Based Learning (PBL), while Experimental Class 2 used Discovery Learning (DL), both assisted by learning videos. Pre-tests and post-tests were conducted to measure learning outcomesand motivation. Results showed average post-test scores of 82.00 for PBL and 76.40 for DL. Students with high motivation scored higher in both models (PBL: 74.27; DL: 74.36) compared to those with low motivation. A significant linear relationship was found between motivation and learning outcomes in both learning models.

Abstract

In stoichiometry learning process, mostly educators focus on calculations. Students are not invited to think more critically about stoichiometry application in life. This constraint makes teachers have to develop new learning models, including Inquiry Based Learning (IBL) model, and Science, Technology, Engineering, Mathematics (STEM) based on chemical literacy. This study aims to develop general chemistry teaching materials on stoichiometry using IBL and STEM models based on chemical literacy that are feasible (valid) and capable of improving students' LOTS and HOTS abilities. The development model used is the ADDIE model, with research subjects of 34 students. The result shows that stoichiometry teaching materials using the IBL STEM model based on chemical literacy are valid (feasible) to be applied in learning with an average score of 4.42 for the material aspect and 4.55 for the design aspect. The developed teaching materials have been proven to significantly improve students’ LOTS and HOTS abilities.
