"Creative teaching" is the most suitable teaching pattern for the training of top-notch talents and the core is the cultivation of elite-class students' autonomous learning ability. We have tried to build the autonomous learning mode in the course of Principles of Basic Chemistry for the elite-class major in polymer materials engineering. The teaching practice has been carried out in six aspects that are "leading both teachers and students to change minds, constructing autonomous learning platform, activating the classroom teaching, complementary integration between PBL teaching method and 'the flipped classroom', 'a line' for extracurricular self-study, and 'point-line-face' generalization and summarization". 相似文献

目的探讨以授课为基础的学习法(1ecture—based learning,简称LBL)和以问题为基础的学习法(Problem—Based Learning,简称PBL)在血液内科见习中的教学效果。方法将2012年及2013年新疆医科大学来我科实习的临床医学专业两个班的学生作为研究对象,分为LBL+PBL和PBL+LBL组,两组采用不同的教学方法,通过闭卷考试测试教学效果,采用问卷调查了解学生对教学方式认可程度。结果PBL+LBL组出科考试成绩优于LBL+PBL组,差异有统计学意义(P〈0.05),问卷调查显示,PBL+LBL组学生更认可教学模式在提高学习主动性和学习效率方面的作用。结论PBL+LBL结合的教学法能充分发挥两种教学法的优势,更加有利于提高教学效果。 相似文献

在抗击新冠疫情期间,北京师范大学"物理化学"教学团队综合利用中国大学MOOC、雨课堂、微信群等多个网络平台和工具,探索并实践了以MOOC授课为基础、以学生学习为中心、以教师辅导为支撑的物理化学远程教学。我们以难度最大的"统计热力学基础"教学为例,设计了包括课前预习、课上观看MOOC视频、实时在线练习、教师答疑、课后反思提问等多环节的复合式教学方案,引导学生利用教师预留的资料、设计的教学活动以及布置的线上作业等实施自主学习。实践表明,这个多环节的综合设计在线课程能够充分调动学生的学习热情,培养学生的自我管理能力,锻炼学生的批判性思维,取得了良好的教学效果。 相似文献

Before teaching a course, the instructor must identify what she or he intends for the students to learn. For most analytical chemistry instructors, this usually involves an assessment of what methods and techniques to include and at what depth to cover them. There are many other skills, though, that will be important to students for their future success. Most college classes in analytical chemistry are taught in a lecture format. Techniques that can be used to improve the learning that can occur during a lecture are described. An alternative to lecturing is the use of cooperative learning. Cooperative learning offers the potential to develop skills such as teamwork, communication, and problem-solving that are more difficult to impart in a lecture format. The laboratory component of analytical chemistry courses is often an underutilized learning resource. More often than not, the lab is used to demonstrate fundamental wet and instrumental analysis techniques and develop rudimentary laboratory skills. The analytical lab should also be used to develop meaningful problem-solving skills and to demonstrate and have students participate in the entire analytical process. Ways of enhancing the analytical laboratory to include more global skills that are important to career success are described.Received January 12, 2003; accepted March 7, 2003

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

Instrumental analysis is the eyes of all research fields. The instrumental analysis course is one of the main courses of university chemistry, and the learning of instrumental analysis course is related to the final output of all chemical disciplines. As an important part of effective teaching and learning, the assessment and feedback can not only evaluate the efficiency, but also guide how to improve teaching and learning. At present, the teaching and learning efficiency of instrumental analysis course is mainly evaluated by homework, classroom quizzes, mid-term and final exam results. The current assessment of instrumental analysis course has the problems of limited forms, the delayed feedback, and the poor interaction of "teaching" and "learning". This paper briefly introduces the reform and practice of effective assessment and feedback in instrumental analysis teaching of Boling class of Nankai University, mainly including three aspects: (1) strengthen the process feedback and let students summarize the points and rules; (2) let students become the center of effective assessment; and (3) carry out the item evaluation of literature reading. 相似文献
