1 当前医用化学实验教学所面临的难题

医用化学实验大多是医学科研实验中的基础内容，是能让医学生成长为医学科研人才的奠基石。然而，在传统教学模式中，老师过多的是以灌输式的教学方法进行教与导[1]，如今许多医用化学的教学仍未从传统教学模式中解放出来，依然面临着种种难题。首先，医用化学实验课程由于医用化学本身的学时少更是被挤压得实验课程的时间少之又少，其次，实验室资源的匮乏也是让实验教学难以展开的重要原因之一，枯燥的理论灌输难以提高学生的学习兴趣，陈旧的实验内容也难以培育学生们的科研能力，要改变当今医用化学实验教学进退两难的局面，将网络虚拟技术、信息化技术以及问题导向式教学法进行优势互补，形成创新型教学模式并植入医用化学实验教学中是医用化学改变旧面貌荣获新生的重中之重。……
