Augmented Reality Educational Game Applications in Science Teaching

Summary

Augmented reality (AR) enhances science teaching by integrating educational games, improving interactivity, and enhancing learning outcomes. Experiments show that AR boosts increase scores by 28 points, with freshmen/seniors gaining 22/30 points. Game indicators (playability and applicability) reach 84%-87%, and user satisfaction exceeds 94%. AR significantly improves performance and classroom effectiveness.

Abstract

With the deep integration of information technology and education, augmented reality (AR) has become a trend in science teaching, combining virtual reality and real-time interaction. This study designs and develops a science teaching system based on AR technology, integrated with educational game mechanisms, to overcome the problems of difficulty in understanding abstract content and low student participation in traditional science teaching. The system is guided by the theories of experiential learning and constructivism, and it integrates algorithms such as feature point tracking, image correction, and regression training. These algorithms improve the accuracy and stability of virtual models in real environments. Finally, a 12-month comparative experiment is conducted in a science and engineering major at a certain university. Experimental results showed that the average score for the science teaching method using AR technology improved significantly, by 20.11 points, compared with the traditional teaching method. The grade of Freshmen in the teaching system increased by 22.36 points, and the average score of seniors in the teaching system increased by 29.97 points. In the science teaching system, the indicators of educational games, playability, and applicability increased to 84, 87, and 86, respectively. Users' satisfaction with the system's usability, content accuracy, responsiveness, and clarity of indicators could reach 97%, 96%, 94%, and 98%, respectively. In summary, the science teaching system using an AR technology educational game has a significant improvement in students' performance and a strong practical effect in the science classroom.

Introduction

Augmented reality (AR) technology has become a necessity, helping people to experience, detect, and inspire, so as to improve life experience¹. This brings heuristic significance to the education and teaching of abstract content. Given the very abstract and difficult-to-observe nature of VR and AR technologies, they can be used² to enhance the effectiveness of education and teaching, so that students' learning potential can be tapped and developed³. Virtual reality technology has interactivity, immersion, and autonomy, which meet the needs of contemporary education. It can be integrated into p....

Results

Evaluation results of educational game experience and learning effectiveness

To verify the scientificity and practicability of the teaching system, the science teaching system developed through an educational game using AR technology is analyzed. To quantify the core performance of the system, technical indicator data is synchronously collected during the experimental process. Under standard experimental conditions (illumination of 300 ± 50 lux), the average tracking success r.......

Discussion

With the development of science and technology, the impact of information technology on people's daily lives spans many fields, and the state also makes every effort to promote the deep integration of information technology with education and teaching. AR technology, with real-time interaction and the combination of virtual and real, is popular in the education industry. Tulgar et al. found, through extensive bibliometric analysis, that AR-based mobile learning and gamification have become the focus of recent research
