我一直从事电大化学教学工作,使我有机会从会议、刊物、资料和实验教学中了解到有关领导、教师和学生对实验课的意见。综合多方面的信息及自己的亲身感受,谈谈对电大的实验课教学的几点看法。一、要充分认识实验课教学的作用实验课教学是化学课教学过程中的重要环节。实验课是学生在教师的指导下,利用实验器材,通过实验引起事物或物质的某种变化,再从观察这些变化的现象分析推理得出结论,使学生获得直接知识验证理论的一种教学手段。实验课教学符合学生的认识规律,有利于学生提高学习质量。学生要把人类已有的科学知识及早的尽可能多的变成自己的认识,并进一步转化为发现、研究和解决新问题的能力,就一定要使这种认识过程符合马克思主义认识论的普遍规律,即列宁指出的“从生动的直观到抽象的思维,并从抽象的思维到实践”的认识事物的辩证途径。在电大教学过程中,做为形成学生的感性认识的“生动直观”大多是演示实验教学,而当学生的认识从抽象的思维进入到 I have been engaged in chemistry teaching at TVU and have given me the opportunity to learn about the experience of leaders, teachers and students in the experimental class from conferences, publications, materials and experimental teaching. Integrated a variety of information and their own personal experience, talk about the experimental teaching of TVU several views. First, we must fully understand the role of experimental teaching Experimental course teaching is an important part of the process of teaching chemistry. Under the guidance of the teacher, the experimental class is a kind of teaching method that students can obtain the theory of direct knowledge verification by using the experimental equipment to induce some change of things or substances through experiments, and then to analyze and deduce the phenomena from the observation of these changes . Experimental teaching in line with the law of understanding of students is conducive to improving the quality of students learning. Students must turn their existing scientific knowledge into their own knowledge as early as possible and further translate into the ability to discover, research and solve new problems, so that such cognitive process must be made consistent with the universal law of Marxist epistemology , A dialectical way Lenin pointed out from his vivid intuition to abstract thinking and from abstract thinking to practice. In the teaching process of TV University, as a “vivid and intuitive” to form the perceptual knowledge of students, most of them demonstrate experiment teaching, and when the students’ cognition goes from abstract thinking
