新的数学课程教学活动具有开放性、创新性,同时也具有一定的确定性。在推进素质教育的今天,各位教师如何根据当前的教育背景,大力开发教育资源,准确预见教学活动发展方向,积极防范可能出现的干扰因素,以更好的实现课程目标,提高教学效果呢?这是一个值得各位教改一线的教师研究的问题。而我们的中学生具有基础差、知识面不广、反应能力较低 The new mathematics curriculum teaching activities are open and innovative, but also certain certainty. In promoting quality education today, how can teachers and teachers develop education resources in light of the current educational background, accurately anticipate the direction of development of teaching activities, and actively prevent possible interference factors, so as to better achieve curriculum objectives and improve teaching effectiveness? It is a question worthy of teachers’ research on the first line of education. And our middle school students have a poor foundation, a lack of knowledge and a low response capacity.
