一、创设问题情境、确定自主探究主题在数学学习的过程中,应顾及学生的情感因素,良好的情绪会使学生积极性和学习效率大大提高。因此,自主探究学习的首要任务是创设问题情境,确立学生自主探究的主题,将学生置身于解决未知问题的氛围中,引起学生自主探究的欲望。以《圆的初步认识》为例,该内容分两次进行,前一次确立探究主题,在计算机房进行;后一次为自主探究成果的交流,在教室进行。以下是自主探究主题确定的片段。师:(媒体展示)你们看,这是老师搜集的 First, create a problem situation, to determine the theme of independent inquiry In the process of mathematics learning, students should take into account the emotional factors, good emotions will greatly enhance the enthusiasm of students and learning efficiency. Therefore, the primary task of independent inquiry learning is to create the situation of the problem, establish the theme of students’ independent inquiry, expose the students to the atmosphere of solving the unknown problems and arouse the desire of students to explore independently. Take the “initial understanding of the circle” as an example. The content is divided into two parts. The theme of the inquiry was established in the computer room and the exchange of independent inquiry results was held in the classroom. The following is a self-exploration theme to determine the fragment. Teacher: (media show) You see, this is the teacher collected
