论文部分内容阅读
四年级的几何初步知识这部分内容,概念、公式多,文字叙述较难理解,画图方法不易掌握。加上教师在选择教法上,重理论,轻应用;重分析,轻操作。因此,学生学这部分知识多是强记定义,死背公式。好学生的成绩仅仅只能从卷面上反映出来,有很大的局限性。绝大部分同学都是学一得一,既不能实际操作,又不能举一反三。为了把单一的知识传授转到既传授知识又注重发展学生能力上来,我在讲授这部分知识时,以思维训练为核心,把对学生的目测和实际操作能力的培养贯穿于教学的全过程。
Fourth grade elementary knowledge of geometry This part of the content, concepts, formulas and more difficult to understand the narrative, drawing method is not easy to grasp. Plus teachers in the choice of teaching methods, theory, light application; reanalysis, light operation. Therefore, most students learn this part of knowledge is strong definition of remembering, death formula. Good grades of students can only be reflected from the surface, there are great limitations. The vast majority of students are learned one by one, neither practical, but also can not get in the same breath. In order to transfer a single knowledge to both impart knowledge and focus on developing students 'abilities, I focus on thinking training while teaching this part of knowledge, and train students' visualization and practical ability throughout the teaching process.
