命题是教师的常规工作,也是教师专业成长的基本手段。本期“专题研究”栏目呈现的四篇文章结合作者高考命题和模拟考试命题的经验,尝试从宏观思考(理论)与微观实践(案例)两个角度诠释数学试题命制的原则、步骤、方法、策略等。希望这样的呈现方式,能引发读者更为全面、深入的思考和实践。 Proposition is the teacher’s routine work, but also the basic means of professional growth of teachers. The four articles presented in this issue of “Research Topics” combine the author’s experience of college entrance examination proposition and simulated test proposition to try to interpret the principles and steps of mathematical test assignment from two perspectives of macro-thinking (theory) and micro-practice (case) , Methods, strategies and so on. Hope that such a presentation, can lead readers to more comprehensive, in-depth thinking and practice.
