Teachers face many difficulties in the motivation, engagement, and improvement of learning outcomes for students in Science, Technology, Engineering, and Mathematics (STEM). In this paper, we present a research study on the learning experience of a new interactive educational 3D video game called Final Frontier, designed for primary school students. This game supports student knowledge acquisition on two Solar System planets Mercury and Venus, and a satellite - Moon through direct experience, interactive challenges and fun. This article compares the learning impact of the computer game-based learning approach with a classic teacher-based learning approach. User experience with the game and game usability are also evaluated. A case study that involved 53 children was conducted for the evaluation. |
