遗传学是生物学中最富于综合性的中心学科之一,是生物学类专业的基础课。如果对遗传学教学采用多媒体教学及传统教学进行对比实验,发现采用多媒体教学的学生成绩明显好于用传统教学的学生。虽然多媒体教学在遗传学教学中发挥着巨大优势,但也存在一些问题,因此就多媒体教学中出现的问题提出一些见解,希望对学院各学科的多媒体教学改革和发展提出有用的建议。 相似文献

<正>一、多媒体教学与计算机辅助教学电子信息技术现已深入社会生活的方方面面,课堂教学领域亦是如此。多媒体教学和计算机辅助教学存在着很多的差异。计算机辅助教学,它反映了教学手段的现代化程度,代表了一种全新的教育思想和教育方式,而多媒体教学更多意义上代表了使用多媒体技术进行教育教学的一种手段。计算机辅助教学的设计目前仍是以教师作为教育教学的中心,这样的教学设计限制了学生学习方式的拓宽和自主学习策略的发挥,而多媒体教学构造的学习环境则会改善很多问题,创造出更加利于学生和多媒体计算机之间进行对话的 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

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

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

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

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献
