【摘要】：随着社会的发展,学生学习主动性的增强,教师在课堂教学中的地位慢慢的退居二线,学生在课堂中逐步扮演着主导角色的观念与之剧增。由于学生在学校学习的时间占据了很大一部分,对于学生在课堂上学习知识的效率高低主要取决于他们学习的方法和体验。在课堂教学中,我们经常对于学生能否充分利用课堂四十分钟时间而达到最为快速的吸收率进行教学改进,那么本文中主要针对学生在课堂中快速接受初中平面向量这一知识点的有关内容进行教学策略的探索与改进,目的是为了让学生在课堂上对于平面向量这个知识点更快的被理解和接受。本文对于初中平面教学中常规教学的一些方法进行了总结,并且对于利用常规教学所导致的一些问题进行了总结与概括,于是针对这些问题,本文着重对于课堂的五个环节中三个环节进行了些改进,首先,在课堂导入部分,所采取的改进措施是将情景设计改为能让学生进行参与的游戏环节,以此来让学生很快地进入课堂,对于所学的知识有了更深刻的反映;其次,对于新课授受这一环节,我采取了让学生通过自己的亲身体验进行归纳总结,对于知识点的概念中的重点和难点进行分辨,这样,能让学生对于新知识的接受远离陌生感,让他们对于平面向量的学习产生了浓厚的兴趣;最后,在例题分析部分,改变了以往教师讲题,学生练习的模式,而是让学生对于例题自行分析,然后通过自己的分析找到解决的方案,通过自己的努力解决问题,而后利用化归思想解决类似问题的解决方法。以上三点的改进措施,本文利用教学案例进行课堂实时记录和学生实际反映的描述,以此来展示对于以上三个方面的改进效果。本文的研究宗旨在于让学生能够积极的参与课堂教学,对于平面向量这一部分的学习产生浓厚的兴趣,并对于知识的掌握起到积极的正面影响,让学生在课堂教学中起到主导的地位,充分发挥他们的主观能动性,不仅在平面向量这一部分的学习中产生积极作用,在其余的教学环节中希望也能发挥积极作用,以此将数学教学真正产生积极效果。
[Abstract]:With the development of society and the enhancement of students' learning initiative, the position of teachers in classroom teaching has gradually retreated from the second line, and students have gradually played a leading role in the classroom. Because students' study time in school occupies a large part, the efficiency of students' learning knowledge in class mainly depends on their learning methods and experiences. In classroom teaching, we often improve on whether students can make full use of the 40 minutes of classroom time to achieve the fastest absorption rate. So this article mainly aimed at the students in the classroom to quickly accept the junior high school plane vector of the relevant content of the knowledge point to explore and improve the teaching strategy. The purpose is to enable students to understand and accept the plane vector in the classroom more quickly. This paper summarizes some methods of routine teaching in plane teaching of junior middle school, and summarizes and generalizes some problems caused by the use of conventional teaching, so aiming at these problems, This paper focuses on the improvement of three of the five links in the classroom. First of all, in the introduction part of the classroom, the improvement measures taken are to change the situation design into a game link in which the students can participate. In order to enable students to enter the classroom quickly, there is a more profound reflection of the knowledge they have learned; Secondly, for the new lesson receiving this link, I adopted to let students through their own personal experience to sum up, to the knowledge point of the concept of the key and difficult points to distinguish, so that, Students can accept new knowledge away from strangeness, so that they have a strong interest in plane vector learning; Finally, in the part of example analysis, we change the model of teacher's lecture and students' practice, but let the students analyze the problem by themselves, then find the solution through their own analysis, and solve the problem through their own efforts. And then use the thought of transformation to solve similar problems. In order to show the improvement effect of the above three aspects, this paper makes use of teaching cases to record the classroom real-time and describe the actual reflection of the students in order to show the improvement effect of the above-mentioned three aspects. The purpose of this paper is to enable students to actively participate in classroom teaching, to have a strong interest in this part of the learning of plane vector, and to master the knowledge has a positive impact on the positive. Let students play a leading role in classroom teaching, give full play to their subjective initiative, not only in the plane vector this part of the learning has a positive role, in the rest of the teaching links hope to play a positive role. In this way, mathematics teaching will really have a positive effect.
