探索了一种以微信公众平台为载体、以案例为启发点、问题为导向,将线上自学、线下讲解和实验训练相结合的多维教学模式,用于无机及分析化学实验教学中。通过期末考试、教学质量评价和问卷调查的方式,从学生学习效果、学习兴趣、能力培养等方面对4个教改班和平行班进行了对比。结果表明,教改班的教学效果明显优于平行班,4个教改班的考试平均分比平行班的平均分高12.6分。新的多维教学模式不仅解决了学生实验效果差、实验室周转紧张等问题,还能充分调动学生学习兴趣、激发实验热情、提升科研素养,为培养创新型人才奠定基础。 相似文献

分析化学实验教学改革包括教学方式改革和实验内容设计方式改革。在教学方式的改革上,由传统的实验教师演示实验为主改革为由理论课教师和实验教师联合授课的教学模式,并加以讨论式和多媒体辅助的教学方法。在实验内容设计方式的改革上,由验证实验为主以提高学生实验操作能力为目标的实验内容,改革成贴近实际的设计实验,籍此调动学生学习的积极性和主动性,增强毕业生的创新素质,挖掘学生的潜能。同时,将节约和环保的理念引入到实验设计中,加强学生绿色化学的概念。 相似文献

In the analytical chemistry laboratory, students were divided into the experiment group and the control group. We adopted the mixed teaching mode, which highlighted the designing Bloom's cognitive goals for education, as well as blending the flipped classroom and the problem-oriented teaching for the experiment group to explore an appropriate teaching mode, aiming at fostering the ability of lifelong learning mainly based on the self-regulated learning. By contrast, the traditional teaching mode was used in the control group. At the end of the course, the effect of the mixed teaching mode was evaluated according to interviews, messages on the teaching platform and the unified test. The results showed that the teaching effect of the mixed teaching mode was better. Moreover, all the students of the experiment group preferred the mixed teaching mode. The teaching practice proved that it was favorable for students to set study goals and build the corresponding self-regulated learning strategies. 相似文献

Modern analytical chemistry is the important professional course for graduate students of analytical chemistry and the related majors. It is the continuation and promotion of knowledge of analytical chemistry course and the key course to improve the scientific research ability of students. The course includes modern separation science, modern electroanalytical chemistry, modern photoanalytical chemistry and advanced analytical chemistry. It is an important guarantee for improving teaching quality to carry out teaching reform of modern analytical chemistry. In the paper, starting from the construction of teaching team, the modern analytical chemistry course group including four courses was set up for the first time. The course contents are reorganized. The teaching methods are optimized and coordinated. The courses are constructed collectively, including reforming the teaching mode and teaching method, editing textbook appropriately and setting up website with a variety of teaching materials. Therefore, the teaching quality can be guaranteed and the disciplinary fundamentals for research work of students can be strengthened. 相似文献
