基于课程标准的教学——以常见阴、阳离子的检验为例

以常见的阴、阳离子的检验为例，研究了如何实施基于标准的教学。校本教材的开发为标准、教材、教学、评价的一致性提供保障；以学生应知的和能做的驱动课堂活动；根据达成标准应有怎样的质量表现，试卷编制先于教学设计。课堂上，“教”“学”双方都明确学习目标，教师提供多种策略来满足学生多样的学习需要，如提供工具，搭建脚手架，并以“微”研究性学习的方式展开教学，给学生提供了充分的进步空间。     

与时俱进，不断开创物理化学课程建设新局面

As a necessary basic theory course for undergraduates majoring in chemistry, materials, pharmacy, chemical engineering, and biology, physical chemistry plays an important role in cultivating talents to meet the needs of social and economic development. Over the years, the teaching team of physical chemistry of East China University of Science and Technology has carried out the curriculum reform and innovation persistently based on "Team building as the foundation, resource building as the root, mode innovation as the soul, ability training as the origin". This paper will summarize our thinking and experience in striving for the first-class course from the aspects of first-class team construction, first-class resource construction, teaching connotation innovation, teaching mode exploration, and extract the experience that can be used as reference by teaching peers.     

化学教学内容情感性艺术处理的策略

化学教学内容是教学系统的基本要素之一。对教学内容作情感性艺术处理,显示了教师高超的化学教学艺术。其艺术策略分为:一是巧妙组织教学内容来调节学生的学习心向,包括心理匹配策略、超出预期策略;二是有效地利用教学内容中的情感资源来陶冶学生的情操,包括展示情感策略、发掘情感策略、诱发情感策略、赋予情感策略。     

市场化改革背景下养老机构服务供给博弈研究

考虑政府补贴、市场化程度、养老机构服务成本、老年人偏好等因素,构建了完全国有化、公私并存的半市场化和完全市场化三种情形下公办和民办养老机构之间的两阶段博弈模型,比较分析了市场化程度对养老机构服务价格制定和服务水平选择的影响,实证讨论了各参数变化对养老机构收益及社会福利的影响。研究表明:完全市场化机制会降低养老机构服务质量,完全国有化机制会陷入社会福利陷阱,探索公私并存的最佳市场化水平才能更好地提高社会福利;适度推进市场化改革,提高养老机构服务水平,降低民办养老机构服务成本,适度提高对民办养老机构的补贴,将有效缓解公办和民办养老机构的不公平竞争;提高老年人支付能力,推进养老机构供给侧结构性改革,将保障机构养老服务的有效供给,促进养老服务业的健康有序发展。

基于“超星直播+学习通”的在线教学示范

为了应对新冠病毒肺炎(COVID-19)蔓延和响应教育部"停课不停教,停课不停学"的号召,作者从"两问题三误区"入手分析了现有在线教学存在的问题,并对比了不同直播平台的优缺点,提出了在线教学的具体教学建议。以基于"超星直播+学习通"的在线教学为例进行了教学示范指导。     

通过教学过程和互动设计保障在线教学的效果

Based on the analysis of the courses and the investigation of students' online learning needs, an online teaching mode of "Tencent Classroom" and "Rain Classroom" with "split screen" is designed. This mode is used for the online teaching of "Foundation of Innovation and Entrepreneurship" and "Chemical Instrumentation and Automation". After two months of teaching practice, the teaching and learning were reflected and summarized, aiming to improve the performance of online teaching.     

“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.     

近5年化学奥林匹克(初赛)试题的分析及建议

从化学核心素养出发，分析近5年化学奥林匹克（初赛）试题考查的学生知识水平、能力水平、素养水平，并针对培养中学生核心素养的教学实践提出建议。     

微视频技术在基础化学实验教学中的实践应用

以高校基础化学实验"从海带中提取碘""三草酸合铁（Ⅲ）酸钾的制备"为例，分别探讨了微视频技术在化学基本操作实验和综合设计型实验中的具体应用；此外，举例说明利用Flash软件制作的虚拟微视频可以在仪器分析实验中清晰地再现仪器真实操作中的每一个步骤，弥补了学生在实验前无法实际操作仪器的不足。实践证明，微视频技术的应用，丰富了基础化学实验教学模式，增强了学生自主学习的能力和动手能力，提高了实验成功率和实验教学效果。
