论数学教师的数学活动教学观

On the Theory of Mathematical Activities:a Aeaching Concept for Mathematics Teachers

数学教学的实质是数学活动教学,即教师指导帮助学生进行教学活动,如观察、描述、操作、猜想、实验、搜集整理、思考、推理、交流和应用等形式.为此,数学教师应树立牢固的数学活动教学观念,形成教师是学生数学学习意义建构的帮助者,学习情境的创设者、提供者,以及数学学习过程的协助者的角色意识.

This author holds that the nature of mathematics teaching is the teaching involved in mathematical activities, i. e. teaching mathematics means the teacher should guide and help his students to try and perform some mathematical activities, including examining, describing, operating, guessing, experimenting, datacollecting/processing, thinking, reasoning, communicating and applying etc. As a result, students can truly understand and grasp what they have learnt and what they are learning. Therefore, to teach well and effectively, mathematics teachers should keep in mind that mathematics is mainly taught through mathematical activities and should form the awareness of different roles: a helper for students?construction of the significance of mathematics learning, a builder and supplier for their learning environment, and a counselor in their mathematics learning process.
