System Usability Scale

The visualization of objects of an abstract nature has always been a challenge for chemistry learners. Thus, augmented reality (AR) and virtual reality (VR) have been heavily invested in as immersive learning methods for these concepts. This study targets the segment of the chemistry curriculum involving the chemical elements of the periodic table. For this purpose, we developed the AR educational tool called MicroWorld. This Arabic educational AR app was developed in unity with Vuforia SDK. Using MicroWorld, students can visualize chemical elements microstructures in 3D, see 3D models of the elements in their substantial forms, and combine two chemical elements to see how certain chemical compounds can be formed. In this work, MicroWorld’s usability was evaluated by junior high school students and chemistry teachers using the Arabic system usability scale (A-SUS). The A-SUS average score was 71.5 for junior high school students, while the scale for teachers reached 76. This research aims to design, develop, and evaluate the AR app, MicroWorld. This app was built and evaluated through the lens of the design science research paradigm.

This research was conducted to develop an integrated science practicum guide with the theme of inquiry-based photosynthesis for junior high school students with student learning outcomes and activities. This research is a Research and Development research with small-scale trials in class VIII A and large scale at VIIIB. The results showed that the practical guide was valid and feasible to use by obtaining an average score of> 3.2 from each expert. After calculating the n gain formula, the classical gain n value is 0.56 (moderate), with the classical completeness percentage is 100%. The results of the analysis of students' understanding using practicum guides have been developed with an average of 83.84. Meanwhile, the understanding of students who did not use the practicum guide that had been developed obtained an average of 62.20. This shows that the understanding of students using the practicum guide that was developed is higher than without using the practicum guide that has been developed. The results of student activity increased after the second meeting with an average of 85.47% of students belonging to the "active" and "very active" categories. So it can be concluded that the integrated science practicum guide for inquiry-based photosynthesis for junior high school students has proven valid and suitable for use in learning.
