学习过程中的问题提出,能让学生在知识学习过程中提出问题、探究解决问题,然后获得新知,能让学生有效理解知识,同时也能提升学生的学习力.“基本活动经验”是指学生亲自或间接经历了活动过程而获得的经验,课堂教学中教师基于这样的经验适当引导,则能让学生自然地发现并提出问题.下面以“双曲线及其标准方程”第一课时的几个教学片断来例述.一、基于椭圆的实验操作,发现并提出探究问题课前准备学具:准备一块纸板、二段细绳、两颗图
The problems in the learning process put forward that students can ask questions in the process of knowledge learning, explore problem-solving and obtain new knowledge, which can help students to effectively understand the knowledge and improve students’ learning ability. Refers to the students experienced in person or indirectly through the activities of the lessons learned, classroom teaching teachers based on such experience appropriate guidance, then allow students to naturally find and ask questions below to “hyperbolic and its standard equation ” first First of all, based on the elliptical experimental operation, find and propose to explore the problem Preparing learning tools: Prepare a piece of cardboard, two sections of the string, two pictures
