聚乙烯吡咯烷酮聚合物复合膜的制备及其性能研究——推荐一个研究型综合实验

A research-based comprehensive experiment was introduced: preparation and investigation of polyvinylpyrrolidone (PVP) blend membranes in which PVP was employed as the membrane matrix. Three kinds of engineering thermoplastics were chosen to enhance the dimensional and mechanical stabilities of PVP based membranes. The physicochemical properties were investigated. This experiment relates to physical chemistry, polymer chemistry, organic chemistry, electrochemistry and instrumental analysis. It covers polymer blending, membrane fabrication by solution casting, characterization and performance test. Through this experiment, students can get knowledge of fabrication and characterization methods for polymer electrolyte membrane, which arouses students' interest in scientific research, cultivates students' innovative ability, fosters students' practical skills and promotes their integrative skills of applying knowledge.     

非化学专业有机化学实验教学中对学生科研思维的培养

研究型大学对学生科研思维的培养至关重要,有机化学实验作为近化学专业类学生重要的基础实验课程,对学生操作技能、创新能力和科研思维培养有重要作用。本文以非化学专业本科生有机化学实验"大学化学实验(O)"的教学实践为例,从学生学习方式、教师教学方法、实验教学内容设置等方面阐述如何在教学过程中完成对学生科研思维的培养。     

问题、项目引领式教学法在高校有机化学教学中的应用

问题、项目引领式教学法可分为问题引领式与项目引领式教学两个部分。问题引领式教学法可用于课程的基础部分教学;项目引领教学法主要用于学生已掌握一定的基础知识之后,教师有针对性地提出一些目前亟待解决的小的项目让学生提出思路及解决办法。通过两种方法的互相补充,可显著提高学生对有机化学这门课程的学习兴趣,也能使有机化学的理论知识与实践能力更紧密地联系在一起,从而提高该课程的教学效果,同时也激发学生创新的潜能。     

启发式及研讨式教学在色谱分析课程中的应用

Based on the chromatography course,we discussed how to cultivate students' interest and creative ability by using heuristic teaching and research teaching mode.Some examples used during the practice were given in the paper.The practice has proved that both teaching modes are important for further improving students' knowledge.     

理论教学与实践教学互相渗透的物理化学教学模式探讨

针对目前存在的物理化学课程中理论教学与实践教学脱节的问题,结合自身教学改革和探索,提出了理论与实践互相渗透的教学模式。实践证明,有意识地将理论教学与实践教学结合起来,可以激发学生学习的主观能动性,深化知识点理解,对提升学生分析问题能力、解决问题能力,以及创新能力都有良好的效果。     

“化学在抗击新冠肺炎疫情中扮演的重要角色”专题教学

Considering COVID-19 epidemic prevention and control, education materials were excavated and refined, such as chemical disinfectants, typical drugs used in clinical treatment or trial and materials for preparation of medical protective equipment. We have carried out thematic teaching on "The important role of chemistry in the fight against COVID-19 epidemic", and integrated ideological and political education into the thematic teaching. Through thematic teaching, we can make students feel the charm of chemistry subject, stimulate students' interest in learning chemistry, fully mobilize students' learning enthusiasm and initiative, strengthen students' confidence and courage to overcome difficulties, cultivate the students' professional disciplines literacy and scientific literacy, activate students' love for the motherland, the people and the Communist Party of China.     

基于便携式多元反馈机制的无机化学混合式教学的实践研究

目前,基于慕课的混合式教学存在反馈手段单一,教学无法充分调动学生积极性的问题,结合多种手机APP,构建了便携式多元反馈机制,分别对课前、课中和课后及单元学习进行多元反馈。基于反馈信息优化教学设计,充分利用各种信息技术,打造讨论型课堂,进行混合式教学。这种"反馈指导教学,教学中有反馈"的教学模式有助于提高学生的学习意愿和教师的教学质量。     

以培养问题解决能力为核心的PMPR实验教学方法

基于"发现、分析、解决问题"的思维模式,本文提出了以培养学生问题解决能力为核心的"问题→方法→过程→结果"(PMPR)实验教学方法。该方法以"问题"为出发点,引导学生进行问题分析,寻找解决问题的方法,实施解决问题的过程,最终得到解决问题的结果。PMPR实验教学方法的实施激发了学生的学习兴趣,拓宽了学生的知识面,实现了对学生发现、分析、解决问题能力的培养。     

利用物理化学基本原理甄别科技文献数据计算的合理性

This in-class teaching design will facilitate students' understanding of how the basic principles and methods of physical chemistry thermodynamics are used to analyze and correct the literature data calculation process in the field of adsorption. Similarly, it will enhance the accuracy and systematicness of students' knowledge of thermodynamics, as well as promote students' interest and self-confidence in learning by employing such a creative and dynamic classroom teaching model of physical chemistry.     

转动课堂在分析化学教学中的应用

"转动课堂"是渤海大学依据地方综合性大学的人才培养目标,借鉴国内外的课堂教学模式引申而来,将课堂精讲与师生互动紧密结合,个性化培养学生的创新能力和动手能力。本文介绍了分析化学结合学科特点及转动课堂核心理念,设计自学、精讲、互动等8个教学环节以提高课堂效率。这种课内课外协同互补的教学模式,激发了学生学习分析化学课程的热情,课堂教学质量及学生学习效果明显提高。
