吉林大学无机化学课程有着优良的历史传承和积淀。面对“互联网+”带来的教与学的新发展和新变革,围绕学生知识、能力和素质三方面的综合培养,教学团队以信息技术为支撑,将课程思政浸润教学,高阶思维贯通教学,建立了“三化、三融、三阶”的线上线下混合式教学模式:“三化”指教学内容层次化、教学资源多样化、评价体系多维化;“三融”指理论课与实验课相融合、专业知识与思政元素相融合、多种教学手段相融合;“三阶”指课前、课中、课后三环节进阶式教学过程。该教学模式可满足学生个性化学习的需求,提升了学生学习的主动性,增加了师生互动,学生的思辨、创新等高阶能力明显提高。 相似文献

阐述了化学教学论课程思政开展思路和逆向教学设计的基本阶段、价值意蕴。逆向教学设计以预期目标为起点,是助力课程思政进展的有效举措。以“说课”为例,探索了课程思政理念下逆向教学设计“设定预期成果—确定评估证据—计划教学指导方案”三阶段规划,并进行了教学过程设计和教学反思。逆向教学设计中教学内容甄选、教学活动设置、教学评价等都指向教学目标,有利于课程育人功能的发挥。 相似文献

在“课程思政”背景下,如何在化工类专业课教学中开展爱国主义教育,是一大挑战。将节能减排所涉及的专业知识作为载体,引入“碳排放”议题作为思政素材,引导学生运用专业知识来解读该议题,将爱国主义元素“无声”地融入专业课教学中。通过解析美国在该议题背后的真实目的和我国的应对策略,激发学生的爱国热情,并使之认识到党在维护国家发展利益方面的决心和能力;通过探寻新中国不同时期的重大历史事件与“碳排放”走势的关联性,使学生深刻认识中国共产党带领中国人民选择了一条正确的道路。本专题教学将专业知识与“思政”元素深度融合,实现了爱国、爱党和爱社会主义3者的统一,对同行教育工作者具有一定的借鉴意义。 相似文献

针对高职产教融合存在的问题,构建了“三三结合式”人才培养模式,即通过“企业指导、行业引导、学校督导”三结合,改革人才培养模式;通过“核心课程、核心问题、核心能力”三结合,深化“教师、教材、教法、教学评价”四教改革;通过“基础实验、专业实验,实习实训”三结合,优化实践教学体系。该模式的构建与实施能提升学生的职业素养,提高毕业生的就业质量,打造出优秀的双师型教师团队。 相似文献

The -electron charges, bond orders, and energy levels of phenoxazin-3-one and eight of its mono- and diannelated derivatives were calculated by the Hückel MO LCAO method. The effect of the position of the annelated benzene ring on the electronic characteristics of the compounds was estimated. A satisfactory correlation between the experimental and calculated energies of the 1 1 transitions was found.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1316–1322, October, 1970. 相似文献

The main aim of the paper is to reinforce the notion that emergence is a basic characteristic of the molecular sciences in
general and chemistry in particular. Although this point is well accepted, even in the primary reference on emergence, the
keyword emergence is rarely utilized by chemists and molecular biologists and chemistry textbooks for undergraduates. The
possible reasons for this situation are discussed. The paper first re-introduces the concept of emergence based on very simple
geometrical forms; and considers some simple chemical examples among low and high molecular weight compounds. On the basis
of these chemical examples, a few interesting philosophical issues inherent to the field of emergence are discussed – again
making the point that such examples, given their clarity and simplicity, permit one to better understand the complex philosophical
issues. Thus, the question of predictability is discussed, namely whether and to what extent can emergent properties be predicted
on the basis of the component’s properties; or the question of the explicability (a top down process). The relation between
reductionism and emergentism is also discussed as well as the notion of downward causality and double causality (macrodeterminism);
namely the question whether and to what extent the emergent properties of the higher hierarchic level affect the properties
of the lower level components. Finally, the question is analyzed, whether life can be considered as an emergent property.
More generally, the final point is made, that the re-introduction of the notion of emergence in chemistry, and in particular
in the teaching, may bring about a deeper understanding of the meaning of chemical complexity and may bring chemistry closer
to the humanistic areas of philosophy and epistemology.

化学学科的现状及基础化学教育改革问题 总被引:29,自引:0,他引:29
1 化学学科现状简介 自 1 80 2年道尔顿提出原子假说 ,1 81 1年阿佛加德罗又提出分子学说以来 ,化学一直在原子和分子学说的基础上发展着。 1 86 9年门捷列夫所发现的元素周期律及在此基础上构成的元素周期表 ,使化学从而成为一门有着严密体系的学科。由于当时对于原子和分子的结构理论还停留在假说的阶段 ,化学家的研究工作主要侧重于元素的发现、分析或分离组成复杂的样品的方法以及新化合物的合成 ,所以化学的传统定义中只强调合成和分析两个方面。这个传统在基础化学教育中至今仍然有着深刻的影响。 2 0世纪物理学家对原子结构及有… 相似文献
