制图教学中创造性构型设计能力培养的探索 总被引：1，自引：0，他引：1
张锡滨 《中国科教创新导刊》2011,(16):79-79
为提高学生的制图学习积极性,提高学生的结构创新与表达能力和解决实际工程问题的能力,我们在组合体构型设计的教学中引入项目引导机制,在教学手段上借助计算机参数化三维建模平台,从而激发了学生自主学习的热情,提高了教学效率和灵活性,培养了学生的创新能力。 相似文献

培养学生空间想象力和抽象思维能力是工程制图教学的关键,点、线面教学是制图教学的第一道难关。在教学中可充分利用职校生形象思维能力强的特点,进行分解基本体、物图转换和图物转换训练,培养空间想象力和抽象思维能力。实物演示和语言叙述两种方法的运用,有助于学生完成点、线、面学习中的画图与读图训练,为组合体画图和读图以及专业制图的学习打下坚实的基础。 相似文献

"工程制图"课程中,组合体尺寸标注的学习一直是难点,主要原因是大一的学生没有相关专业课的知识支撑,只能机械地学习和记忆,导致这部分内容学习效果不好。针对组合体尺寸标注中的难点问题,提出了相应的解决方法,并在教学中进行了实践,提高了学生对组合体尺寸标注的理解,取得了较好的教学效果。 相似文献

在教学过程中，笔者针对如何教学生读组合体视图作了一些探索。根据大纲的要求，结合课程教学内容及学生的实际情况，笔者确定了两个教学目标。一是知识目标：引导学生真正理解形体分析法和面形分析法的核心、要领，做到巧妙地应用。二是能力目标：培养学生的空间想像能力、分析问题和解决问题的能力。 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

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

People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 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

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context. 相似文献
