中职生对文化课的重视程度远远低于其专业课,大部分中职学生基本没有学习数学的动机和兴趣。基于此,许多数学教师都喜欢从中职学生的兴趣出发设置一个具体的情境导入新课。本文在此背景下提出目前数学课堂导入的一些误区,并结合自身教学实践给出有效课堂导入的案例分析,指出有效的课堂导入不仅仅是要考虑学生的兴趣,更要关注其背后的数学关系。
Secondary vocational students pay more attention to the cultural class than their specialized courses, and most secondary vocational students have no motivation or interest in learning mathematics. Based on this, many math teachers like to set a specific situation from the interest of vocational students to import a new lesson. Based on this background, this paper puts forward some mistaken ideas in the current introduction of maths classrooms and presents an effective case-based case-based analysis of the classroom teaching. It is pointed out that effective classroom introduction should not only consider students’ interests, but also pay attention to the mathematical relations behind them .
