High impact on students’ understanding of atomics radius on crystals geometry concept through implementation of JITT with 3D animation

This study was conducted to analyze the students 'initial and final understanding after the application of JITT with 3D animation, to identify students' responses and arguments, and to determine the impact of using JITT with 3D animation. This research involved 43 students of the 6th semester of the 2019-2020 academic year of the Physics Education study program of the Universitas PGRI Kanjuruhan Malang who took solid state physics course. Students' initial and final understanding was analyzed through responses and arguments presented during the pretest, while the impact of JITT application with 3D animation was analyzed based on the results of the pretest and posttest as well as student responses during the learning process expressed through short interviews and discussions. The qualitative and quantitative data generated from the mixed-method approach were analyzed simultaneously. The results show that the students understand that the atomic radius for all the different crystal lattices is the same, namely a/2. This was awakened by an early understanding of the general definition of the radius. However, after following the JITT stages with 3D animation, their understanding changed that the atomic radius of each crystal lattice is different in length. In addition, the results of statistical analysis showed that there was a very significant increase in the students' mastery of concepts from an average of 26.9 to 96.7. Meanwhile, the N-gain value is very high, namely 0.96 in the very effective category, which illustrates that JITT with 3D animation has had a high impact on students' understanding of atomic radius in the concept of crystal geometry

Meta-Analysis of the Relationship Between Learning Media in Hybrid Learning and Critical Thinking and Creativity in Science

The 21st-century learning paradigm is characterized by integrating technology into learning facilitating flexible and accessible learning experiences. One such model is hybrid learning, enabling education to transcend time and place with technological aid. Amidst this backdrop, it is crucial that hybrid learning provides education and fosters essential skills of the 21st century, including critical thinking and creativity. This research endeavors to establish a connection between the learning media employed in hybrid learning and the enhancement of critical thinking and creativity skills within the Science and STEM education context. The study also investigates the utilization of laboratory-based applications in chemistry instruction. Employing a meta-analysis approach with descriptive analysis methods, the researchers scrutinized 50 articles cataloged in Scopus, focusing on publications from the past decade. The meta-analysis findings unveil a significant effect size of 0.87, indicating a substantial correlation between the use of learning media and the cultivation of critical thinking skills. Moreover, the association between hybrid learning's learning media and creativity skills is evidenced by an effect size of 0.94. Consequently, it can be inferred that a substantial correlation exists between learning media in hybrid learning and the development of creativity and critical thinking abilities. The impact of laboratory-based applications and software in science education, particularly chemistry, is greatly influenced by pedagogical aspects and instructional strategies
