《福建省小学数学学业质量监测命题工作指南》对“双向细目表”明确指出命题要求:认知维度中的了解占20%、理解占40%、掌握占30%、运用占10%;内容维度中的“数与代数”占50%、“图形与几何”占35%、“统计与概率”占15%。这就从“高度”、“宽度”给命题的教师和答题的学生提出了针对性、实效性、挑战性要求,同时也给教与学提出了更高的要求。下面仅围绕引导学生解决选择性问题谈四个常 The Worklist of Quality Supervision Proposals for Maths in Primary Schools in Fujian clearly states that the propositions require that 20% of the students understand the knowledge, 40% should understand, 30% should be mastered, and 10% should be used. The “” and “algebra” in the content dimension account for 50%, the “graph and geometry” account for 35%, and the “statistics and probability” account for 15%.
