Sunshine News (Reporter Yang Xiaojuan) On the afternoon of May 7, the No. 1 Primary School of Yanta District, Xi'an City, launched the seventh phase of the "Weekly Lessons, Zhou Zhousi" series of activities.
This lesson is a lesson of "Understanding Right Angles" in the second unit of the second volume of the second grade taught by Ms. Fan Yu. Teacher Fan combines real-life examples to let students experience the process of abstracting right angles from actual objects, guiding students to intuitively understand right angles, and cultivating students' spatial concepts. Combined with the operation activities, students are inspired to identify right, acute and obtuse angles with the help of triangles, so that students can realize that the results of such operations are more accurate than direct observation, and cultivate students' spirit of seeking truth and pragmatism.
The theme of this seminar is: how to better develop students' spatial concepts. To cultivate students' spatial concept, it is necessary to connect with the reality of life, respect the cognitive laws of students, start from observation and operation, help students establish appearances, summarize the essential characteristics of geometric shapes through connection and comparison, and pay attention to accumulating experience to guide students to apply them in practice. For example, in this lesson, starting from the objects that students are familiar with, it stimulates students' enthusiasm for learning, activates students' life experience, establishes a preliminary spatial concept, and develops visual thinking. Therefore, attaching importance to cultivating students' spatial concept not only helps students better understand the world and solve problems in daily life, but also lays a good foundation for further systematic learning of geometry knowledge in the future.
