基于移动终端的PBL教学 对小学生元认知能力的影响研究——以小学科学课程“地球的运动”为例

The Influence of PBL Teaching Based on Mobile Terminal on the Primary School Students’ Metacognition — A Case Study of Primary School Science %22the Movement of the Earth%22

ith the rapid spread of mobile devices， educators are very interested in using mobile devices to teach and to learn. Metacognition on the learning process of monitoring and regulation is usually expressed as students of learning ability， thus the teaching supported by technology should pay attention to cultivate students' metacognition. This study combines the information teaching model of APT， designs the PBL teaching model based on the mobile terminal， and takes the elementary school science course ＂ the movement of the earth＂ as an example to carry out the teaching activities and a quasi-experimental study was designed to explore the difference between PBL teaching based on the mobile terminal and the traditional teaching on the primary school students' metacognition. The results suggest that: (1) PBL teaching based on mobile terminal has better effect on students' metacognition but there no significant difference with control group; (2) Compared with the traditional teaching， PBL teaching based on mobile terminal has a significant positive impact on students' achievement; (3) PBL teaching based on mobile terminal will not increase the of students' cognitive load and may be appropriate to reduce the students' psychological burden.
