                    非专业大学生化学实验面临的问题与解决方案

                    时间:2019-03-19 13:09作者:曹雷刚 杨越 焦志伟
                    本文导读:这是一篇关于非专业大学生化学实验面临的问题与解决方案的文章,目前,工程教育专业认证已经在越来越多的高等学校开展,促使国内高等学校相关专业开始进行合理的教学改革,制定明确的课程体系并能持续不断的进行改进,以期培养达到行业认可的高素质毕业生。

                      摘    要:棋牌大全下载安装 工程教育专业认证工作对理工类专业自然科学类课程有明确的要求,这也促使了大学化学课程在非化学类理工科专业覆盖面进一步扩大。课程授课学生人数的增加,给大学化学实验教学环节带来了压力。分析了化学实验的重要性和面临的问题,讨论了新形势下非化学专业实验课程的授课内容和具体授课方式。

                      其次,正常情况下,单次参与实验的组数和每组人数越少,越有利于保证良好的教学质量。然而,由于学生基数较大,在实际过程中,单次组数和小组人数极难维持在较低水平。如若学校条件允许,扩大实验场地可以提高单次实验学生容量,但需要更多的实验辅助人员和更多的仪器设备,经费投入也将成为一个较大的问题。
