中考、会考、高考试题“源于课本、高于课本”的趋势越来越明显了.相应地,老师们溯考题之源、变课本之题也越来越热了.这是一个值得称道的苗头.因为,对课本的回归,与题海战术相对立,可以有效地减轻学生负担,使学生的数学能力较轻松地得到真正的提高. 我认为,编拟课本变式题应遵循严密的科学性与明确的目的性相结合的原则,不应为编而编,为变而变,更不能越编越难,越变越玄,形成新的题海.
The tendency of the “high school textbooks, textbook exams, and textbooks” in the high school entrance examinations, college entrance examinations, and textbooks is becoming more and more obvious. Accordingly, it is more and more ardent for teachers to search for the source of the questions and change the subject of the textbooks. This is commendable. Since the return of textbooks is opposed to the sea tactics, students’ burdens can be effectively reduced and the students’ math ability can be truly improved. I believe that the preparation of the textbook variant should follow strict science. The principle of combining sex with a clear purpose should not be edited, changed, changed, or even made more difficult, more and more mysterious, to form a new topic.
