【摘要】：小学数学广角是人教版小学数学教材中的特色板块,是课程改革后在人教版小学数学二年级到六年级教材中增列的内容。它是数与代数、图形与几何、统计与概率以及综合与实践四大领域之外的内容。数学广角是以生活的情境为载体,让学生从实际生活背景中抽象出数学问题,进行数学思考,建构数学模型,自主探索解决问题方法的单元内容。数学广角教学主要是让学生在学习数学广角知识的同时学习数学思想方法,对活动经验进行积累,提高创造力和发展数学思维。但是由于该板块出现时间相对较晚,对其研究比较少,在实际教学中,教师对数学广角的教学依然存在着很多的困惑。鉴于此,本文针对数学广角的教学进行研究,以期发现数学广角教学中存在的问题,根据问题分析原因并找出解决对策。根据调查发现了目前小学数学广角教学的现状及其存在的问题:教师对数学广角内容认知不到位;对数学广角教学目标定位不准;教学方式的选择上忽视了学生的主体性;教学实施忽视了问题的解决过程;教师不注重数学广角的教学反思等等。究其原因,主要表现在以下几点:教师对教学内容不重视,教学研究欠深入;不重视教学目标,再分析不足;教师过于注重知识的传授;对问题的解决过程关注不够;忽视教学反思的重要性等等。通过对小学数学广角教学问题的归因分析,提出了小学数学广角的教学策略:提升教师专业素养,深入开展数学广角内容的研究;立足全面发展,准确定位教学目标;更新观念,确定学生学习的主体地位;关注生成,让学生参与学习过程;注重数学广角的教学反思等等。希望通过本文的研究,针对性地提出优化数学广角教学的策略,为小学一线数学教师的教学提供借鉴和参考。
[Abstract]:The wide angle of primary mathematics is the characteristic plate in the teaching material of elementary school mathematics, which is added to the textbook of grade 2 to grade 6 of elementary school after the reform of curriculum. It is beyond the four fields of number and algebra, graph and geometry, statistics and probability, and synthesis and practice. The wide angle of mathematics is to take the situation of life as the carrier, let students abstract mathematical problems from the actual life background, carry on mathematical thinking, construct mathematical models, and explore the unit content of solving problems independently. The main purpose of wide-angle mathematics teaching is to let students learn mathematics ideas and methods while learning mathematics wide-angle knowledge, accumulate activity experience, improve creativity and develop mathematical thinking. However, due to the relatively late emergence of the plate and less research on it, teachers still have a lot of confusion about the wide-angle teaching of mathematics in practical teaching. In view of this, this article carries on the research to the mathematics wide angle teaching, in order to discover the mathematics wide angle teaching existence question, according to the question analysis reason and to find out the solution countermeasure. According to the investigation, the author finds out the present situation and existing problems of wide-angle mathematics teaching in primary schools: the teachers do not know the content of wide-angle mathematics, the goal of wide-angle teaching is not orientated correctly, the choice of teaching methods neglects the students' subjectivity; The implementation of teaching neglects the process of solving the problem; the teacher does not pay attention to the wide-angle teaching reflection of mathematics and so on. The main reasons are as follows: teachers do not pay attention to the teaching content and the teaching research is not deep; they do not attach importance to the teaching objectives and then analyze the insufficiency; the teachers pay too much attention to the teaching of knowledge; they pay less attention to the process of solving the problems; Ignore the importance of teaching reflection and so on. Based on the attribution analysis of mathematics wide angle teaching in primary school, this paper puts forward the teaching strategies of wide angle teaching in primary mathematics: to promote teachers' professional accomplishment, to carry out the research of mathematics wide angle content, to base on the overall development, to locate the teaching goal accurately, and to improve the teaching quality of mathematics. Renew the idea, confirm the main body position of the student study; pay attention to the generation, let the student participate in the study process; pay attention to the mathematics wide angle teaching introspection and so on. It is hoped that through the research of this paper, the strategy of optimizing wide-angle teaching of mathematics can be put forward, which will provide reference and reference for the teaching of mathematics teachers in primary schools.
