观察是知觉的最高形态,是最基本、最重要的科学探究技能之一,是一切科学研究的基础。因此,要引导学生对植物的生长变化进行有效观察相当重要。一、把握科学课堂实验活动主阵地科学课堂实验活动是学生直接获取知识经验,证实事物因果关系、解决科学疑难问题的、实现学生动手动脑能力的活动。充分利用好课堂实验活动这个主战场,科学教学活动才会丰富多彩具有吸引力。1、把握科学教材中易于操作的实验活动科学教材的正确使用是上好科学课的关键。教师应根据学生的年龄特点和知识水平以及不同区域的特点,选择适合学生操作的实验,进行相关的活动。生硬难懂,不适合本
Observation is the highest form of perception and is one of the most basic and important scientific inquiry skills and the foundation of all scientific research. Therefore, it is important to guide students to observe the changes of plant growth effectively. First, to grasp the scientific classroom experimental activities The main front of the science classroom experimental activities are students directly acquire knowledge and experience, to confirm the causal relationship between things, to solve scientific problems, to achieve the students brain activity. Make full use of the main battlefield activities in the classroom, science and education activities will be colorful and attractive. 1, to grasp the scientific teaching materials easy to operate experimental activities The correct use of science textbooks is the key to good science class. Teachers should be based on the characteristics of the age and knowledge of students and the characteristics of different regions, the choice of experiments suitable for students to conduct related activities. Hard to understand, not suitable for this
