教师要提高教学水平,必须不断地总结经验,不断扩大知识领域,阅读、收集教学参考资料,并根据自己需要选取合适的材料用于教学中。为了更有效地运用收集到的材料,须对资料进行整理、分类和编集,建立“教学档案”,用时则取之,不用则存之。 相似文献

1“教师为主体”的旧的教学模式被瓦解代之而起的是“学生为主体”的新的教学模式在教学过程中,我们一直强调学生是学习的主体。但传统的教学方法很难发挥学生的主观能动性。教学活动仍是以教育者为中心,以语言传播为主要手段的活动。教师是知识的传播者和专家,学生是学习者和听从者。一张嘴、一支笔、一本教材、一叠讲稿的局面在很大程度上限制了学生主体作用的发挥。而教师的主导作用是由教师各方面的因素决定的,如教师的知识掌握程度、语言表达能力、组织教学的能力、对学生的认识和态度、师生关系的处理、教师的精力和工作情绪等。… 相似文献

仅以教会知识为目标的化学教学是一种“把种子磨成面粉”的教学。如何才能在学生的心灵里种下化学的种子,让其成为一个有化学智慧的学生呢?让教学充满原创力,充满历史感,着力于建构化学观念的教学才能让学生生成化学与人生的智慧。 相似文献

针对后疫情时代的教学需要和地方高校的信息化教学资源的不足,通过创建微信公众号和微信群,初步探索了微信融入无机化学实验教学的新模式。课前通过公众号的推文引导学生进行有目标的预习,养成自主学习和独立思考的习惯。课堂中,先通过微信群进行预习测试,并基于测试反馈调整需要重点讨论的实验要点,再通过微信群共享师生在实验过程中对实验操作、实验现象和实验结果拍摄的照片或视频,充分激发学生兴趣,提升学生的能力。课后结合拍摄的错误操作的照片撰写公众号推文,进行实验反馈,帮助学生形成反思的习惯。 相似文献

This paper aims at the implementation of the online courses of chemistry majors in Sichuan University in response to the epidemic, and explores a more effective and reasonable way to organize teaching. Based on the investigation and feedback of teachers and students, this paper points out the difficulties and challenges of online teaching at the present stage:the classroom interaction and discussion are not smooth, the online teaching tools and methods are diversified, and the chemistry laboratory courses are not matched. Therefore, the School of Chemistry of Sichuan University will coordinate the online teaching platform, enhance the classroom interaction, and launch the "chemistry virtual simulation experiment teaching center" to ensure the teaching progress and quality during the epidemic prevention and control. 相似文献

The Sino-foreign educational cooperation program is one of the important forms of higher education in China. The innovation and exploration of teaching modes and methods were carried out to tackle problems in teaching inorganic and analytical chemistry laboratory at Beijing University of Chemical Technology. These problems can be found in logical thinking, combining basic theory with practice, and software used in treatment of experimental data. The teaching reform was carried out on the aspects of improving students' innovative consciousness, combining theory with the experiment, integrating ideological and political education into classroom, application of software in experimental data treatment, which will improve the subjective initiative and problem-solving ability of students in learning inorganic and analytical chemistry laboratories. It will lay a solid foundation for the students of international bioengineering class to successfully connect with foreign follow-up courses in the future. 相似文献

In the era of "Internet +", with the help of national excellent MOOC course of Chinese university and Mlabs-virtual experimental software, Tencent classroom is built to provide a diversified and efficient online inorganic chemistry basic laboratory classroom by combining a variety of modern education technologies with the concept of flipped classroom. Taking the redox reaction experiment as an example, we designed a multi-link teaching process and carried out a multi-faceted assessment. The online teaching can not only strengthen the cultivation of students' comprehensive and innovating ability, but also help teachers to update the teaching mode and create the new experimental content in line with the development of the times, so as to realize the mutual learning between teachers and students in the exploration of experimental teaching reform. 相似文献

Due to the outbreak of the COVID-19 epidemic, the new semester has been postponed. But in order to continue teaching and student training work, teachers from colleges are efficiently utilizing internet education resources, and actively carry out online teaching. This paper uses one of the virtual simulation experiment projects at Shandong University, as an example. It introduces how to conduct online laboratory training and teaching in inorganic and analytical chemistry laboratory by utilizing the combination of virtual simulation experiment projects and online resources, and help student learn the theory and operation of iodometry titration. 相似文献
