The objectives of the project study were to 1) create the treasure hunting in a real ancient ruin simulation game 2) evaluate suitability of the treasure hunting in a real ancient ruin simulation game and 3) assess satisfaction of game players to the game. The data collected by selective method consisted of 2 sample groups including 3 experts to evaluate suitability of the game who were specialist about 3D VR Game Design and History and 30 game players the treasure hunting in a real ancient ruin simulation game who were ages between of 15-35 years. Statistical data analysis was mean and standard deviation. The results showed that the treasure hunting in a real ancient ruin simulation game overall satisfaction was at a high level (𝒙̅=3.83 S.D.=0.50). Players of the treasure hunting in a real ancient ruin simulation game had overall satisfaction was at a high level (𝒙̅=4.35 S.D.=0.65).

At present augmented reality (AR) technology has an essential role in peoples daily life. It has widely established in medicine commerce education just to name a few. This work presents the development of educational media in astronomy using augmented reality (AR) technology via website. It supports an inquiry-based learning (IBL) which is the one of pedagogy approaches for the 21st century education. Applying AR in educational media creating a 3D astronomy environment in the topic of solar systems making learners more motivated and eager in astronomy inquiry in order to construct scientific knowledge. Furthermore a post-test is conducted to observe the learning outcome from the educational media. To evaluate the development of educational media in astronomy using augmented reality (AR) technology the results showed the overall average satisfaction score of the system was 4.63 with a very satisfied level. Moreover it performs properly according to its mentioned objectives.

The special project on Transformative Tray with Pedestal from Tinted Glass Design by Lego Technique has the objectives to study the design and procedure of the transformative tray with pedestal from tinted glass design by lego technique and to investigate the satisfaction of the target group towards the transformative tray with pedestal from tinted glass design by lego technique. The researchers conducted the study and collected the data related to a sketch design of the transformative tray with pedestal from tinted glass design by lego technique which can be modified into 3 ways a rice funnel tray a holy-water bowl tray and monks alms bowl tray. 5 experts will consider the structure of three trays and choose the lotus petal pattern a tray and the color of the lotus petals that the experts like and it must be most suitable.

Then bring the data into the analysis by using frequency percentage and mean. The result of the analysis shows as follows. From the design and procedure of the transformative tray with pedestal from tinted glass design by lego technique it was found that most experts agree that all three tray are suitable size and proportions for the transformative tray with pedestal from tinted glass design by lego technique. A wooden tray should be used because the lotus petals are plump and delicate. Because the wood tray is strong and the tray should be embedded with glass for a match the colors should be contrasting colors to make the pattern stand out. There should not have additional decoration because the work is outstanding with the pattern of tinted glass. Suggestions for delicate work should be planned and should have a smooth glazing.
