| Summary: | 碩士 === 國立新竹教育大學 === 資訊科學研究所 === 100 === The competence indicators for “The Moon Phase Unit” in the field of "Science and Life Technology" in Grade 1-9 curriculum include: the observation of the rising and setting of the moon and the sun, and by daily observation of lunar phase to find the periodic waxing and waning of the moon. However, the observation of lunar phase is often restricted by time, place and weather, causing the incorrect concepts of students in learning “The Moon Phase Unit”.
In this study, the Tablet PC based on Android platform was used as a mobile device, and context awareness combined with augmented reality (AR) technology was used to develop a moon observation system which can be used anytime and anywhere without the restriction of weather conditions. A teaching experiment was conducted through the learning achievement tests of the lunar phase concepts, questionnaire survey and interviews to collect data in order to understand the influence of the moon observation system relative to students’ learning achievement and their attitudes.
In this study, a quasi-experimental research was conducted by dividing students into experimental and control groups by selecting two fifth-grade classes of 56 students in an elementary school in Taichung. The experimental group used the moon observation system to assist instruction and the control group used traditional teaching method; the objective was to investigate the difference of learning outcomes. A survey for the degree of acceptance in science teaching model and interviews were also conducted as a reference to verify the results of this study and the performance of the moon observation system as well.
The results showed that the moon observation system can enhance students' conceptual development of the lunar phase; the questionnaire survey and interviews revealed that 90% of the students preferred to use the system for observing the moon, and they generally believed that the system could help them obtain the information of lunar phase and record data. Regarding the system interface, most students thought that the user interface was clear and easy to use, and they would use the moon observation system first with similar demands in the future.
