高考化学题库内部结构的设计

Design for Inner Structure of Item Bank for Chemistry Test of College Entrance Examination

题库内部结构是指导题库命题设计的重要理论依据,试题的参数指标系统和试题在各个指标上的分布状况是题库内部结构设计的主要内容。本文结合高考化学学科知识体系和命题方式所具有的特性,对化学试题参数指标系统和化学试题在各个指标上分布状况进行精心设计,确保化学题库的内部结构能够准确反映化学试题的内容和结构特征,能够合理规划试题布局。

The design of inner structure of item bank mainly includes the item indexes system and the distribution of each index, which can be regarded as an important theoretical basis for the writing of items for item bank. Based on the knowledge system of chemistry subject and the characteristic of item writing style, this paper described the indexes system of chemistry items and the designing process of the distribution of each index in detail. The resulting inner structure can precisely reflect the content and structure features of chemistry items. It can also accurately indicate the storage status of items and the feasibility of distribution of item structure.
