Abstract

This study aims to determine the feasibility and practicality of interactive learning media based on augmented reality for carbon compounds. This research is a type of development research that adopts the 4D model (define, design, develop, disseminate) but is limited only to the development stage (develop). The population in this study consisted of 124 students from SMAN 1 Labuhan Haji. The sampling technique used in this study was random sampling. The assessment aspects evaluated by three validators have three aspects measured through expert validation sheets. The level of practicality of the media was measured through a practicality questionnaire sheet completed by 24 students of Class XI MIPA at SMAN 1 Labuhan Haji. The results showed that the level of media feasibility, as assessed by the validator, was 0.68, indicating that the developed media had a high level of validity. The results of the media practicality test showed that students gave positive responses to all media components, with a practicality percentage of 87.5%. Based on these results, it can be concluded that the media developed is feasible and practical to use.

Abstract

Project-Based Learning is an instructional strategy that improves students' Science Process Skills (SPS) by involving them in hands-on scientific project design and implementation. This study investigates the effect of PjBL on students’ SPS, focusing on skills such as observing, generating hypotheses, planning experiments, using tools and materials, collaborating in groups, and communicating scientifically. The research follows a quasi-experimental design with a pretest-posttest control group, including two XI classes at SMAN 1 Lembar, selected through purposive sampling. One class (XI-1) is assigned to the experimental group, which uses PjBL, while the other (XI-2) is the control group, which follows traditional teaching methods. The study uses a science process skills test as the research instrument. The N-Gain analysis showed a moderate improvement of 0.335 in the experimental group, compared to a minimal improvement of 0.011 in the control group. A t-test (t = 6.84 > t = 1.673 at the 5% significance level) confirmed the significant effect of PjBL. The results indicate that PjBL effectively enhances students’ scientific skills, critical thinking, and creativity, making it a viable and innovative approach for science education. These results suggest that PjBL can be foundational to developing more integrated, context-driven approaches to science learning.
