基于互联网+生物化学新教学模式的建立

The rapid development of internet technology has made the access to knowledge more convenient and diverse, which is both an opportunity and a challenge for traditional teaching methods. By analyzing and comparing the characteristics of four advanced teaching methods and techniques, and addressing the specific curriculum features and students' situation, a new mixed teaching model was constructed by Traditional Classroom Teaching Model (TCTM), Small Private Online Course (SPOC) and Flipping Classroom Model (FCM). The proportion of the three teaching methods was about 50%:35%:15%, respectively. By striving to combine their strengths and develop students' learning and reasoning ability gradually, the proposed mode achieved a satisfactory teaching effect.     

分析化学实验教学的可视化和标准化模式构建

多媒体计算机辅助教学与传统方法相结合,录制实验基本操作和实验过程的录像,运用二维码扫描技术采集实验数据及计算机编程分析处理实验数据,构建可视化、标准化的分析化学实验课教学模式。多年的实践表明：教学效果得到有效提高,实验课学生的实验报告平均分数达到90左右;学生数据处理能力普遍提高,期末考试及格率达到90%,平均成绩达到75分左右;激发学生的科研积极性,50%以上的学生参加了国家、天津市及学校的大学生创新项目;提高了学生的实验技能水平,在近2年天津市大学生化学竞赛中,获得一等奖2项,二等奖2项,三等奖2项的好成绩。     

医用基础化学“沉淀溶解平衡”的教学思考与设计

沉淀溶解平衡发生于非均相体系,这种现象在医学和生命科学领域广泛存在,例如骨骼的形成、龋齿的产生、肾结石与尿结石的形成等等。为了使医学学生能够更好地理解和掌握本知识点,笔者在教学设计中,紧密结合“问题导向式”教学模式,以医学案例作为切入点,以疾病的产生原因和预防措施作为结尾,首尾呼应;在教学形式上体现出教与学的互动性,不但收到很好的教学效果,而且还可让学生带着问题学习,激发学生的学习兴趣和主观能动性,有利于培养学生探究问题、解决问题的能力,让学生成为会独立思考、有创新能力和创新思维的人。该思路可延伸到《医用基础化学》的其他章节内容,具有普遍的指导意义。     

高中化学原子核外电子排布教学模型设计及应用

为加深学生对原子核外电子排布规律的理解，帮助他们快速掌握核外电子排布的书写，设计了2种教学模型：“台阶模型”和“台阶房子模型”。向学生介绍了这2种模型，并用试题和访谈了解他们的学习效果，结果良好。这2个教学模型可供中学化学教师在教学中参考和使用。     

我国目前中学化学实验研究述评

通过报刊检索法,以3种中等化学教育核心期刊为研究对象,分析出目前我国中学化学实验研究主要分为3种类型：理论研究;经验总结或理论运用;具体实验设计。同时分析出：我国中学化学实验研究设计角度较为全面,但方法水平总体不高,对新课程下的实验设计研究不够。解决的途径为：加强实验设计的理论研究;更新广大一线教师的教育理念;提升中学化学教师实验设计水平。     

物理化学课程在线教学实践与效果分析

The main measures and experiences of online physical chemistry teaching through Ding Talk platform in Bohai University was introduced. Through the practice of the whole semester, it can be seen that the modular teaching mode of "simplicity-detail-induction" constructed by physical chemistry teaching team is conducive to match students with different self-learning abilities with different levels of teaching. The question-and-answer video induction class can fully arouse students' learning enthusiasm, which is favorable for the perfect realization of teaching and teacher-student interaction. With the double guarantee of meticulous and transparent teaching management and the accompanying process assessment, the overall goal achievement degree of the whole semester reached beyond 80%, and the sub-goal achievement degree reached over 60%, which provided reference for relevant teaching.     

形象化教学方法在药学专业化学类课程中的应用

In view of the complex knowledge points and some abstract theories of pharmaceutical chemistry courses, the application of visualized teaching methods to present important knowledge points in a vivid way can enhance the teaching effect and stimulate students' interest in learning. Based on the authors' teaching and research work, this article summarizes the application of figurative teaching methods such as metaphor and analogy in inorganic chemistry and medicinal chemistry courses.     

基于产品开发能力培养的混合式教学实施探索——以现代化妆品科学与技术课程为例

How to take the student as the center and the OBE (Outcomes-based Education) concept as the guide to comprehensively cultivate students' professional ability and professional quality has become an important content of applied undergraduate teaching reform. Taking "Modern Cosmetics Science and Technology" course as an example, an online and offline blended teaching implementation mode based on product development skills and literacy was constructed. It includes diversified teaching methods, immersive learning atmosphere, PBL (Problem-Based Learning) product projects, special anchors, and technical expert status conversion. The feasibility was implemented and verified.     

无线可视化显微熔点仪的研制与教学应用*

基于熔点测定实验教学特点,结合智能移动设备与无线WiFi技术的优点,研发出新型无线可视化显微熔点仪(热台法)应用于教学,并获国家实用专利授权。相比目前高校教学中常用市售目视显微熔点仪(热台法),新型仪器具有部件成本低模块化、操作方便自动化、过程显示可视化、记录存储可溯化等特点。通过新研仪器的“一对多”无线可视化观测模式可有效解决常规目视显微熔点仪测定实验教学效率低、教学效果差、卫生安全隐患大等实验教学痛点。     

初中化学“溶液”的项目式教学——制作天气瓶

以制作天气瓶为项目核心与溶液单元知识进行整体融合。经过认识天气瓶、揭秘晶体变化奥秘和自制天气瓶等一系列活动,学习多角度认识溶液的组成、溶解度和科学的定量实验设计方法。溶液形成过程的微观本质是学生的学习难点,应用多个电导率仪测定不同位置的离子浓度变化,形成硝酸钾溶解过程曲线,通过分析曲线数据变化很好地搭建起宏观辨识与微观探析间的桥梁,帮助学生突破学习难点。学生在解决这一复杂、综合实际问题的过程中,有效地发展了宏观辨识、变化观念、证据推理、科学探究、创新精神等化学学科核心素养,发展了科学价值观。
