在化学教学中,实验不仅能增加学生学习的兴趣,还能增强学生对实验现象的记忆和总结及分析实验结论的能力.化学实验是培养学生科学素养的重要途径,也是促进科学探究的主要方式.以实验为基础是化学的基本特征,使实验现象清晰呈现,是学生获得丰富的感性认识的重要途径.在化学教学中,特别是实验演示中,如何使教学效果更有效呢?一、充分准备,使实验演示更有效化学教学课前准备是一个至关重要的环节,特别是在开展实验探究活
In chemistry teaching, not only can the experiment increase students’ interest in learning, but also enhance students’ ability to remember and summarize the experimental phenomena and analyze experimental conclusions.Chemical experiment is an important way to cultivate students’ scientific literacy and is also the main way to promote scientific inquiry Based on the experiment is the basic characteristics of chemistry, the experimental phenomenon is clearly presented, is an important way for students to obtain a wealth of perceptual knowledge in chemistry teaching, especially in the experimental demonstration, how to make teaching more effective? First, the full Prepare to make experimental demonstrations more effective Chemical instruction preparation is a vital part, especially when it comes to experimental inquiry
