高等学校教学改革的目的是为了充分激发学生学习的主体性和积极性,在大一无机化学实验教学中开展跨学科的综合性实验,在人力物力财力上都有一定的难度。我们认为改造现有实验使之综合化是一个低成本高效率提高教学效果的好办法。教学实践的效果证明:我们开展的“由锌焙砂制备硫酸锌及主含量测定”———这一改造现有实验且具有跨无机化学和分析化学两大学科性质的较大范围的综合性实验,有效激发了学生的求知兴趣,充分调动了学生学习的积极性、主动性,在培养学生综合实验能力方面取得了很好的教学效果。
The purpose of the teaching reform in colleges and universities is to fully stimulate the subjectivity and enthusiasm of student learning. It is difficult to carry out comprehensive interdisciplinary experiments in freshman inorganic chemistry experiment teaching. We think that it is a good way to improve teaching effectiveness at low cost and high efficiency by rebuilding existing experiments. The effect of teaching practice proves that we have conducted a “the preparation of zinc sulphate from zinc calcine and determination of the main content ” --- This experiment has been modified and has a wide range of properties across the two major disciplines of inorganic chemistry and analytical chemistry The comprehensive experiment effectively aroused students ’interest in seeking knowledge and fully aroused the enthusiasm and initiative of students in learning, and achieved good teaching results in cultivating students’ comprehensive experimental ability.
