Abstract:

In this paper, we tried to integrate the concept of number sense, experiential curriculums and mobile learning devices into a useful mechanism to help the learners to easily establish the quantitative intuition of weight and promote the abilities of estimation by connecting the feelings of muscle and scales of tools. Based on the theory of multiple intelligences , quantitative intuitions of weight is a special kind of bodily-kinestthetic intelligence. The way of improving quantitative intuition of weight differs from the one of improving the others. Besides, based on Bruners’ theory of scaffolding, the teachers have to offer the adapting scaffoldings for the students by correct procedure to make sure that the students could develop strategies and construct knowledge. Therefore, we tried to erect the mechanism by applying RFID technology to help the students improving quantitative intuition of weight. In this experiment, there were 58 fifth grade students of an elementary school who were divided into the experimental and control groups, randomly. The testing course was quantity and measuring of mathematics. From the experimental results, the proposed mechanism could help the students to learning the concept of conservation and sorting, efficiently. The effectiveness is better than which by using the traditional teaching strategy and up to a significant level. However, there was no significant difference in learning the concept of combination and division, because it might take a longer period to learning these two concepts . In term of relevant, the effectiveness of mathematics achievement and learning achievement has no significantly correlation, because the traditional tests can not evaluate the actual quantitative intuition Similarly, there was no significant correlation between boys and girls, except the learning achievement of the concept of sorting, because the girls are more patient.
