教学研究不仅能提高教师的专业水平,而且也能揭示数学问题的本质,以便更好地服务于教学实践,因此笔者一直崇尚“以研促教、以教思研”的教学理念,并将其融入自己的教学行为.在教学实践中,笔者对下列问题进行了不断思考和反思,并对其进行了一些有益的拓展.笔者以为,该过程能展现我们一线教师“草根式”的教学研究,故将探索心得整理成文,供读者参考.题目如图1,在长方体AB-
Teaching research can not only improve the professional level of teachers, but also reveal the essence of mathematical problems in order to better serve teaching practice. Therefore, I have been advocating the teaching concept of “research, teaching and research” In the teaching practice, the author of the following issues have been thinking and reflection, and carried out some of its useful expansion.I think that the process can show our front-line teachers “grassroots” Teaching and research, it will explore the experience finishing text, for readers reference topics in Figure 1, the rectangular AB-
