“投影和视图”知识作为初中生必修知识内容2001年进入了《义务教育数学课程标准》。通过对立体图形、三视图、展开图的学习培养学生空间概念的能力;随着学生升学的发展,数学的学习难度也将逐渐增强,“投影和视图”作为“高中立体几何”知识点的基础内容,占据着中学数学的重要学习地位,“投影与视图”也是中学生中考的重要知识考点,故该知识点的学习就尤为重要。同时在机械生产加工、制造、日常生活等方面“投影和视图”也有着广泛的应用。投影与视图在古代艺术文化、时间计量等领域也占据着重要的作用。在生活中总能见到各种鲜明的实例,学好该知识点也有助于培养学生的综合素质能力。
“Projection and view ” knowledge as a compulsory knowledge content for junior high school students entered the compulsory education mathematics curriculum standards in 2001. Through the study of three-dimensional graphics, three-dimensional view and expanded image, the students ’ability to cultivate the concepts of students’ space is enhanced. With the development of students progressing into mathematics, the learning difficulty of mathematics will also be gradually enhanced. The “projection and view” The basic content of knowledge points, occupy an important learning status of high school mathematics, “Projection and View ” is also an important test of secondary school entrance examination knowledge, so the learning of knowledge points is particularly important. At the same time in the mechanical production and processing, manufacturing, daily life, etc. “projection and view ” also has a wide range of applications. Projection and view also play an important role in ancient art culture, time measurement and other fields. In life can always see a variety of distinctive examples, learning this knowledge point also helps to develop the overall quality of students ability.
