| Summary: | 碩士 === 國立中央大學 === 網路學習科技研究所 === 102 === Several researchers recently indicated that individual’s spatial ability and learning achievement of geometry have a significant positive correlation. Out of that most of the researchers employed a questionnaire including mental rotation or spatial visualization to test individual’s spatial ability. However, the individual’s ability in perceiving the real object size or the distance to the object has not been thoroughly investigated so far. In this study, we developed the ubiquitous geometry (UG) learning system to support students to learn about geometric concepts, and to enhance their motivation to perform real world measurements. 75 fifth grade students were participated in this study during five weeks, where they were divided into three groups with different learning ways. We investigated the difference of geometry learning achievement and measurement estimation ability among three groups, and further explored the relationship between the learning behavior and learning achievement.
In the geometry test, the results show that experimental group performed better than control groups I and II. The results of measurement estimation test represent that the experimental group performed better than control group II. Moreover, irrespective of the kind of learning way used, students’ geometry learning achievement has a positive correlation with their measurement estimation ability. The results of the learning behavior analysis show that the amount of aid suggestion feedbacks has a positive correlation with learning achievement. In the peer competition, the amount of competition, the highest score of competition and the amount of review competition have positive correlations with learning achievement. The amount of actual measurement has positive correlations with their learning achievement and measurement estimation ability. Finally, most of the participants had a positive attitude towards the UG system and the designed activities, and expressed that the UG system helped them to enhance their measurement ability and knowledge on geometric concepts effectively.
