新课程理念下的数学课堂,要扣住学生的心弦,教师就要认真钻研教材,精心备课。要激发学生的求知愿望,使学生乐于学习,就要重视“引入”的教学。新的学习理论尤其是建构主义学习理论给我们提供了更为科学的理论依据,本文对新课程理念下的数学教学,“引入”的教学进行了初探。新的教学理念打破了陈旧的教学模式,强调建构主义学习。新课程理念下学生的学习是主动建构知识的过程,教学是使学生主动学习,乐于学习的过程。“良好的开端是成功的一半”。笔者非常注重新课的导入,教师的授课效果在很大程度上取 Under the new curriculum philosophy of mathematics classroom, to catch the students’ hearts, teachers should carefully study materials, meticulous preparation lesson. To stimulate students’ desire for knowledge, so that students are willing to learn, we must attach importance to “introduction ” teaching. The new learning theory, especially the constructivism learning theory, provides us with a more scientific theoretical basis. This paper probes into the teaching of mathematics under the new curriculum concept and the teaching of “introduction”. The new teaching philosophy broke the old teaching model, emphasizing constructivist learning. Under the new curriculum concept, students’ learning is the process of taking the initiative to construct knowledge. Teaching is a process in which students actively study and are willing to learn. “Well begun is half done”. The author attaches great importance to the introduction of the new lesson, the teacher’s teaching effectiveness to a large extent
