<正>在微信、微博、微电影盛行的微时代,微课也出现在教学中。微课是指以视频为主要载体,记录教师围绕某个教学内容或教学环节开展的简短、完整的教学活动(音视频)。与传统课堂教学不同,微课时间短(510分钟),内容少(只讲解一个知识点)。如何制作微课呢?我认为要做到有声有色,因为学生学习微课主要通过听和看的方式。一、制作有声微课制作有声微课要求教师利用自己的语言、语速、语调和背景音乐等,从听觉上调动学生学习的积极性,提高辅导效果。教师录制微课一定要在安静的环境中进行,微课视频中的声音只能是授课教师的声音和背景音乐。(一)教师语言无论微课的呈现形式多么新 相似文献

自从课堂教学引入微课后,对教师们的教学理念产生了重要的影响.那么,什么是微课呢?就是教师根据自己学生的知识水平储备情况和接受能力,将教学内容制成短小的视频,上课时以视频的形式将教学内容呈现给学生.教师最为关注的是如何制作高水平的微课视频,达到预期的教学目的.教师首先要有制作视频的仪器设备和软件,还要拥有制作视频的能力,更为重要的是深入挖掘教材内容,充分利用与之相关的课程资源,这样才能更有针对性地选择合适的素材,制成的视频才能有效地体现出教学目标. 相似文献

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F. 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

Different nations have different social cultures, and the social culture of every nation is developing with the development of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in conceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language. 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献
