为了提高制图课的教学质量,测验和命题是一个重要的教学环节.我们在这方面作了一些改革,现总结如下.一、测验命题和方法改革的具体办法体现在测验方法的四个结合及命题的四种方式上.即在有计划的复习基础上实行复习与测验相结合,开卷与闭卷相结合,内容全面与测验方式多样化相结合,基本作图技能与专业应用相结合.测试命题的四个方面是:1、制图基础理论方面(成绩占20%)把画法几何部分总结为10个思考题,例如:设空间点M与(V、H)等距,N与(V、H、W)均等距,试想它们在空间的定位轨迹有何规律?一般位置平面上能否同时作出(V、H、W)三向平行线,为什么(举图例论证)?当回转体轴线垂直于H面时,试分析其三投影特征有那两大共性?试以不等径二园柱为例,论证由于直径变化(量变)引起相贯线形位变化(质变)的规律?采用开卷考试,测试题提前一周印发给学生.测验时,每人抽答一题.这样就既迫使学生事前必须全面准备,无法投机取巧,考后又将不同答案发给学生分组评议,最后由任课阅卷老师作结论.
In order to improve the teaching quality of drawing lessons, quizzes and propositions are an important teaching link.We have made some reforms in this respect and are summarized as follows: First, the specific methods of testing propositions and methods of reform are embodied in the four combinations of testing methods and Proposition of the four ways, that is, on the basis of a planned review of the combination of review and test, the combination of open book and closed book, the content of a comprehensive and test mode of combining the combination of basic drawing skills and professional applications. The four aspects are: 1, the basic theory of drawing (20% of the grade) summarizes the geometric part of the painting into 10 questions, for example: Let space point M and (V, H) equidistant, N and H, W) are equidistant, imagine their regularity in the space locating trajectory? The general position of the plane can simultaneously make (V, H, W) three parallel lines, why (as illustrated)? When the revolving body axis vertical On the H surface, try to analyze the three common characteristics of the projection? Try to unequal diameter two columns as an example, demonstrate the change of diameter (volumetric change) caused by intersecting linear shape change (qualitative change) , Test questions issued to students one week in advance , Each pumping answer one question. This will only force students to be fully prepared in advance, not opportunistic, and then test different answers to students grouped council, and finally by the classroom teacher grading draw conclusions.
