关键词： 情境教学   议题   课程发展   设计内容   课程内容   教学模式   认知活动   情感活动  

摘要： 核心素养培养要求开启了政治课向活动型课程转变的征程。专家提出“课程内容活动化”与“活动设计内容化”相兼容的课程发展方向，明确了实践活动型课程的着力点在议题创设。李吉林在《情境教学精要》中指出：情境教学是通过创设优化情境，激起儿童热烈的情绪，把情感活动与认知活动结合起来的一种教学模式。

关键词： 信息技术整合   语文课程   有效整合   初中   教学方式   课程内容   认知工具   学习资源  

摘要： 初中语文课程与信息技术整合是把以信息技术为中心的各种资源同语文课程内容结合的一种新型教学方式。在语文教学中,信息技术可以作为信息处理的工具,可以作为多元认知工具,可以提供丰富的学习资源,可以展示和发展思维,有效地改善教和学的方式。一、含义语文课与信息技术整合是指在语文课教学过程中把信息技术、信息资源、人力资源和课程内容有机结合,共同完成教学任务的一种新型的教学方式。

关键词： 抽油机   换向装置   非圆齿轮   行星轮系   仿真  

摘要： 针对现有抽油机换向装置存在的效率低、稳定性差等问题,设计一种非圆齿轮行星轮系换向装置。该装置采用W-W型行星轮系,应用非圆齿轮传动,在输入端角速度恒定的情况下实现输出端的正反转运动,从而完成抽油机的自动换向。齿轮传动具有传动效率高,稳定性好的特点,可有效解决抽油机换向时存在的问题。通过换向装置设计实例,进行理论分析及ADAMS仿真,分别得到输出摆角及角速度变化曲线图,通过对比分析,从理论上验证了该设计可实现抽油机的平稳换向。

关键词： 小学课程   课程设置   课程内容   课程类型  

摘要： 近代我国小学课程经历从传统走向现代的重要历史演变。1878年上海正蒙书院的设立,标志着我国最早的小学成立,小学课程出现了萌芽。此时小学课程缺乏统一的标准和规范性,并带有浓厚的封建色彩。我国自颁布第一个学制到1922年新学制颁布,小学课程经历了草创、改造、革新三个阶段。期间,小学课程体系逐渐完善,课程内容经历了从注重成人到以儿童为本位、从单一的道德价值取向到多元的社会价值取向、从传统走向现代的演变。每个阶段小学课程都呈现出一定的变化,主要表现在课程设置的种类、课程的类型、课程的时数等,同时也反映了不同阶段课程的价值取向。

摘要： ObjectivesThe aim of this study was to re-examine the teaching of geriatric dentistry in the USA dental schools, to identify curriculum content and compare the findings to previous reports. MethodsAll dental schools in the United States were contacted via email with a questionnaire to assess the teaching of geriatric dentistry. Non-responding schools were sent a minimum of three reminder emails to complete the survey. A statistical analysis was performed. Descriptive statistics were conducted to profile the variables of interest. Bivariate analysis was performed to explore if any of the variables were related using Fisher's exact test, non-parametric Wilcoxon rank-sum test and the Kruskal-Wallis test. ResultsFifty-six of the 67 dental schools completed the questionnaire. Geriatric dentistry was taught in all dental schools;for 92.8%, the course was compulsory. We found that 62.5% were teaching it as an independent course, 25% as an organised series of lectures and 8.9% as occasional lectures in parts of other courses. Clinically, 84.2% have some form of compulsory education in geriatric dentistry. Public schools were marginally associated with an increased interest in expanding the geriatric dentistry curriculum (P=.078). No differences were found between these variables and school location. ConclusionsGeriatric dentistry is now required in 92.8% of dental schools. The teaching of traditional topics has not changed much;however, the number of gerontological topics has increased. Clinical teaching needs to be expanded, as in only 57.1% of schools was it a requirement. The ageing imperative will require research to determine the impact of teaching on services to the geriatric community.
