Innovations in Chemistry Teaching in Secondary Education: Integrating Augmented Reality and Project-Based Learning to Improve Student Comprehension and Interest
Main Article Content
Abstract
The goal of this study, called "Innovations in the Teaching of Chemistry at the Secondary Level: Incorporating Augmented Reality and Project-Based Learning to Improve Understanding and Interest," is to see how using Augmented Reality (AR) and Project-Based Learning (PBL) together affects third-year secondary students' understanding of chemistry and interest in it. The most important reason for this study is to find solutions to the challenges with science education, especially when it comes to teaching an abstract subject like chemistry, that are produced by traditional frontal teaching and expository methods. A mixed-method approach with a quasi-experimental design was used, which included both an experimental group and a control group. There were 60 kids in the sample who were chosen on purpose. The experimental group used the PBL technique and augmented reality (AR) to see if interactive learning tools could help them understand difficult chemical ideas. A formative assessment was done for analysis. It included a diagnostic test and a post-test, surveys on how students felt, semi-structured interviews, and both statistical inference and thematic coding analysis. The results clearly showed that the experimental group's academic performance was far better than the control group's. The experimental group's average post-test score (M = 8.42, SD = 0.78) was much higher than the control group's (M = 6.11, SD = 0.93), and the difference was statistically significant (p < 0.001). Also, interviews showed that students were more motivated and grateful for chemistry as a subject that is helpful and relevant to real life. This study reveals that using AR and PBL in the classroom is a good way to change the way things are done, encourage students to be more independent, and make learning more relevant and inclusive. It is possible that this combination of methods could be used in other educational settings to improve the teaching of natural sciences at the high school level.
