我们农技师院所培养的是既要有技术性又要有师范性的人材,也就是说他们既要掌握一定的农业技术知识又要有传授知识的本领。这就要求我们要培养好学生的实践技能、总结能力和表达能力,而实验教学就是培养学生能力的重要课堂,所以如何上好实验课是摆在我们面前的重要任务。然而传统的化学教学虽然重视实验教学,但是他只是验证书本上的理论,并且结论和实验结果却受着教材和教师的限制,学生很少有主动 Our agro-technician institutes cultivate talented people who are both technical and teacher-friendly. In other words, they must acquire both certain agricultural technology knowledge and knowledge-imparting skills. This requires that we cultivate students ’practical skills, summarize their abilities and express their abilities, and that experimental teaching is an important classroom for training students’ abilities. Therefore, how to do a good experiment is an important task before us. However, although the traditional chemistry teaching emphasizes experimental teaching, he only verifies the theory of the book, and the conclusions and experimental results are limited by the teaching materials and teachers. Few students actively take the initiative
