一种创新学习的路径：“观点及其持续推进”知识建构过程

The Process of Knowledge Construction of "Point of View and Its Continuous Development": A Path to Innovative Learning

文章考察了小学三年级科学课堂中的知识建构活动，通过多种数据的收集与处理，了解学生知识创新学习的路径与效果。研究结果发现：小学三年级学生在知识创新学习中，其知识量的扩展远远超出课程标准及教材的“限制”，研究问题的深度在不断地加强，学生之间观点的交互程度也在不断提高；通过知识建构的学习，超越了个体知识，形成了社区公共知识。同时也说明了知识创新学习的关键是要坚持以观点的提出及其不断深化和发展的路径。

Our research group are devoting ourselves to apply the theory in science classroom of elementary school and guide students to put forward their "ideas" concerning the water/the water pollution independently. In order to construct a system of elementary students' scientific knowledge and research methods, we use many kinds of teaching strategies to promote the sustainable development of ideas. The results show that the key of knowledge innovation is to insist on the path that students put forward ideas and work continuously to improve them;After being engaged in knowledge building, the third grade students have learned far beyond the curriculum standard and teaching material;Knowledge building should be an activity with clear objectives, student's knowledge building tends to be more theoretical and more systematical as scientists' work;Knowledge building is not intended to form personal knowledge, but to create knowledge of value to the community.
