有效教学中学生表现出来的情绪有主动、积极、愉快。学生在学习过程中对所学内容有主动加工的心理倾向和加工能力。要想让学生的学习活动在每节数学课上达到预定的教学目标,必须一开始就要将学生的注意力吸引过来,从而尽最大可能地调动学生的学习积极性。在教学过程中,要特别注意每一节课的导入过程,所谓良好的开端是成功的一半。不管是哪种导入方式,最基本的导入都是在旧知基础上向新知过渡。因为数学知识都是相互连贯的,新知总是以旧知为基 The effective teaching of the emotions shown in the students active, positive and happy. Students in the learning process on the content of the initiative to process the psychological orientation and processing power. In order to make the students 'learning activities reach the predetermined teaching goal in every math class, the attention of the students must be attracted from the beginning so as to arouse the students' learning enthusiasm to the greatest extent possible. In the teaching process, pay special attention to the introduction of each lesson, the so-called good start is half the battle. No matter what kind of import, the most basic import is based on the old knowledge of the transition to the new knowledge.
