    Everyday hundreds of thousands of tons of waste goes to landfills, although more than half of it could be either recycled or composted. The waste management situation tends to get worse when there are many poorly-designed landfill sites that could either leak hazardous chemicals which can contaminate groundwater or emit harmful gases into the atmosphere. These health hazards or environmental chain problems could be diminished if everyone sorted their waste precisely. To mitigate this problems, we aim to tackle it from the beginning. Thus, in this work, we propose a computer-based VR game called SEPBO. SEPBO is an educational game which aims not only for enjoyment, but also to improve the players' waste sorting skills. The experimental results confirm that SEPBO is a better tool to improve the players' waste sorting skill compared to the interactive web-based baseline, ReCollect: The Waste Sorting Game, in ALL aspects: with 6.67% higher performance in improving players' waste sorting skill and a 48% greater degree of satisfaction than the baseline in terms of enjoyment.

    Thinkercise was developed to be an educational VR game for reviewing knowledge and skills in Python programming. The game not only encourages players to move their physical body during the gameplay but also prompts players to use their basic Python programming knowledge and skill to complete a task in the game. In the gameplay, players are required to answer a series of programming related questions by moving their body in various ways in a limited time, such as punching a target, or avoiding an obstacle. To achieve the maximum score, players need to hit the correct answer targets at the right time as well as to avoid all obstacles in the game successfully. Experimental results demonstrate that our game helps increase the students' performance in computer programming by 40.8%. It outperformed self-learning by 30%.

    Engineering drawing is one of the important fundamental subjects in the engineering course that requires imagination and artistic skill for understanding. Engineering student needs to practice a lot of exercises to understand three-dimensions representation and its two dimensional orthographic in top view, front view and side view. However, some students cannot understand 3D objects by just only paper and pencil. This process makes them feel bored to practice. Therefore, they cannot understand well and might have a long-term issue. Therefore, this paper proposes virtual reality 3D games as a learning media by using Oculus Rift and Oculus Touch. The objective of this game is to help students or people who have a previously mentioned problem to improve their skills. This game will increase the enjoyment of learning and possibly motivate them to educate the understanding of 3D objects and their visual dimensions. In this game, the player must match 3D objects with orthographic projections and create the object by themselves to match an orthographic projection. A player can register and check their improvement from history score and time spent. The goal of this virtual reality learning game is to motivate the player to practice with happiness. The experimental results showed players used shorter time and had got higher accuracy when continue playing. Post-questionnaire results shown they feel most enjoying when creating 3D virtual reality objects by themselves. Moreover, the results could imply students below grade C+ in Engineering Drawing subject may have problems with 3D objects that were cut into triangular in prismatic shapes, and students below grade D+ may have problems with dashed and solid lines.
