一、问题的提出职业中专数学是职高高考、“三校生”高考主课程和某些专业课的核心课课程,教学目标呈现多元化趋势,在整个中职教育中具有举足轻重的地位和作用。如在笔者学校的单招高考班以及焊接、汽修、幼师等专业班级中,数学课都非常重要。同时,学生们对数学课教学也提出了较高的要求:一是能够听懂,二是能够活用,三是教学要有一定的趣味性。在笔者学校2012年5月中期考试后的学生民主评教中,大多数学生都从这三个方面对教师的日常数学教学进行了评价。教师在实际教学中要做到上述三点,有一定的难度。一是职业中专数学自身的特点决定了教学有难度。数学具有一定的抽象性,需要学生具备一定的逻辑思维能力,如果不能学而得其要领,极容易让学生有枯燥乏味的感觉,从而使他们对数学产生畏惧甚至厌倦的心理。所以,即使 First, the problem raised Vocational secondary mathematics is vocational high school entrance examination, “three school students ” college entrance examination main courses and some specialized courses of core courses, teaching objectives diversified trend appears in the entire secondary vocational education has a pivotal position and role . As in the author’s school single-stroke entrance examination classes and welding, auto repair, kindergarten and other professional classes, mathematics classes are very important.
