高中数学教学注重学生通过分析、概括等方式归纳出数学概念,通过探究、推理等方式建立数学定理或公式。由于高中数学概念或定理比较抽象,我们可以尝试在教学中引进问题情境的创设。问题情境的创设能有效激发学生的归纳和推理能力,是改善高中数学教学效果的重要途径,也是落实课改精神、实施素质教育的重要手段。因此,我们在教学中要根据不同的教学内容和学生认知基础,设计具有一定启发性,有利于激发学生探究欲望的问题情境,促使学生用适合自己的数学思维主动探究和掌握数学知识。1在情境中设置悬念,有效激发学生的好奇心在情境设计中恰到好处地留下悬念,能有效激发学生学习时的积极心理状态,使学生在好奇心驱动下
High school mathematics teaching focuses on students through analysis, generalization and other ways to sum up the concept of mathematics, through the exploration, reasoning, etc. to establish mathematical theorems or formulas. Because high school mathematical concepts or theorems are abstract, we can try to introduce the creation of problem situations into our teaching. The creation of problem situations can effectively stimulate the students' abilities of inducing and reasoning. It is an important way to improve the effect of high school mathematics teaching and is also an important means to implement the spirit of curriculum reform and carry out quality education. Therefore, according to different teaching content and students 'cognitive basis, we should design a certain enlightenment situation that is conducive to inspire students' desire to explore, and make students take the initiative to explore and master mathematical knowledge with their own mathematical thinking. 1 set suspense in the situation, effectively stimulate the curiosity of students in the context of the design just left a suspense, can effectively stimulate the students to learn the positive psychological state, so that students are driven by curiosity
