视频生动形象的直观画面深受聋人喜爱,但由于聋人的听力受损,使得聋人对视频的信息处理面临诸多困难,无法有效接收、理解视频内容。为此,文章以聋人的自适应学习需求为导向,确定了包括数据处理、用户定位、字幕匹配和无障碍字幕呈现四个环节的聋人视频无障碍字幕设计流程。同时,文章介绍了两个典型的聋人自适应学习场景:面向聋人的交互式视频资源平台和人工智能技术支持的聋童识字阅读,并分别提出了相适的无障碍字幕设计方案。进行基于自适应学习需求的聋人视频无障碍字幕设计,不仅有利于提升聋人的学习兴趣并有效、完整地接收视频信息,而且在一定程度上促进了聋人的教育公平。 相似文献

文章从学习认知和学习满意度层面,通过实验测量了学习者对四种呈现方式的教学视频进行自主学习的效果。研究结果表明:在学习认知方面,A(视频类+解说字幕)组别的教学视频学习成绩最好,有解说字幕比无解说字幕的教学视频学习成绩好;在学习满意度方面,视频类教学视频比图文类教学视频的学习满意度高。并在此实验结果的基础上,从教学视频资源建设和基于教学视频的自主学习层面提出了建议。 相似文献

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity. 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
