初中数学探究性活动设计的基本思路

结合自己的教学实践,探索初中数学教学中探究性活动的设计思路.在实际教学过程中,要把握探究性活动中涵盖的数学思想、方法和策略,要重视探究性活动对学生身心发展的整体影响.本文围绕探究性活动的内容,通过一个探究性活动的课堂实例和习题拓展设计探究性活动,展开相关研究.     

新工科视阈下石油化工类高校应用化学专业课程体系重构

Taking a typical local and industry-orientated applied chemistry major as an example with focusing on the major changes in the form and content of the petrochemical industry, the way to reform the core curriculum system and teaching contents is presented. Based on the changing tendency of refinement of the petrochemical industry, a complete curriculum system with distinctive industry characteristics is set up according to the principles of the emerging engineering education (3E) with several reasonable suggestions. A new model for the construction of a 3E major in chemistry-related majors is suggested. It is a good reference for the construction of curriculum systems for other local and industry-orientated colleges who want to make 3E reform.     

You do,you learn”的启示

加大课堂教学改革力度，更新教育观念，突出以学生为本的教学，以学生为主体，立足于学生的发展，给学生提供动手动脑的机会，让学生亲自实践，在做中学，在玩中学，在快乐中学。     

“双一流”背景下高等农业院校有机化学基础课程教学新模式的构建及实践

The crop science of Sichuan Agricultural University is an authorized first-class discipline. As the strategic supporting department for innovative talent cultivation in agriculture and forestry major, we are facing a long-term challenge in reforming the teaching mode for basic course-organic chemistry and cultivating talented students with solid basic knowledge and strong sense of innovation. Herein a thorough survey was performing to establish the executable teaching programs for this course during the "Double-First Class Universities Plan" period. A multidimensional teaching resource library for organic chemistry course was also constructed. The new classroom teaching mode "Interest cultivation-Creative thought development-Autonomous and Cooperative learning", along with a stepwise practice teaching mode "Foundation skills-Integrated application-Innovative trial" was proposed and practiced among thirty-five majors including agriculture, forestry and veterinary, to improve the quality for innovative talent cultivation and support our first-class discipline construction. This research could probably serve as a reference for congeneric agricultural university.     

综合治疗脑梗塞68例观察

脑梗塞是常见病，且大部分可引起偏瘫，失语，智能障碍等后遗症，严重影响病人的生存质量，广州市第六人民医院于１９９５年１月～１９９７年６月采用中西药物，传统治疗，功能障碍治疗，心理治疗，氦氖激光血管内照射，血液光量子疗法，高压氧等综合治疗脑梗塞６８例，总疗程３个月，结果，总有效率９４．１％，显效率６４．１％，明显高于单用药物治疗的显效率，说明综合治疗可提高疗效，减少后遗症及致残率，且病程越短，疗效越好     

例谈物理核心素养视角下培养学生策略性学习的实践研究

文章结合自身教学实践,针对在物理核心素养背景下,从"借助项目设计,培养学习习惯,促进学生‘策略性学习’反应程序化""借助过程优化,积累学习方法,促进学生‘策略性学习’研究深度化""借助物理与生活互动,提高学生对学习理解,促进学生‘策略性学习’运用实践化"3个途径来提升学生思维水平,发展学生思维品质,进而提高学生物理核心素养.     

正交试验法优选穿心莲内酯硫酸酯化反应工艺

硫酸酯化反应以分子结构中的羟基为反应位点,向有机分子中引入硫酸酯基,是一种有效改善天然产物水溶性的结构修饰途径[1]。有些药物因水溶性差,致使其在临床应用中存在一些问题,如生物利用度不高,服用量大,制成的片剂或胶囊体内吸收缓慢等。这类化合物经硫酸酯化后不但可以增加     

基于STEAM教育解决照相机成像实验难点

照相机成像实验一直以来被一线教师忽视,重点强调原理的解释而忽略实际成倒立像的展示.生活中的照相机和手机成像都是正立的,学生没有见过照相机光学成倒立像的现象,不符合学生的前概念认知.STEAM教育的核心理念是跨学科整合教学,自制照相机较好体现了STEAM教育中工程、艺术、科学与数学的结合.开发照相机成像的教师实验和学生分组探究实验,简单易行,解决了困扰一线教师的实验制作难点问题.     

新时代下物理教师追求职业幸福感的实践探究

新时代下物理教师必须怀着对事业的敬畏之心,带着一种职业幸福感,投身于教学与德育工作,方才有实效,最终造福学生.本文主要通过笔者自身的工作实践,从勤写论文、培训提升、班级管理、阅读素养等方面,探究寻找职业幸福感的方法与途径,从而激发教师自身的创造性,达到师生共赢的效果.     

高中物理“学科德育”实施指南和实践路径探寻

日常课堂教学多数物理教师还是忽视"学科德育"的实践,即使存在一定的"学科德育"实践,也比较随意、凌乱,缺乏系统模式建构.尝试构建高中物理"学科德育"实施指南和案例,期待能为高中物理乃至其他学科提供"学科德育"的实践路径.
