通用技术选考试题综合难度的应用研究——以浙江省技术选考电子控制技术试卷为例

Application Study on Comprehensive Difficulty Coefficient Model of General Technology for Elective Subjects of College Examination:Based on Test Questions for Electronic Control Technology of Elective Subjects of Zhejiang Province

结合浙江省技术选考试题特点,运用试题评价的综合难度模型,以2018年11月至2020年1月3套浙江省技术选考试题为研究对象,从背景因素、认知水平、思维推理、逻辑运算、知识综合等五个维度进行分析。研究发现:3套试题整体难度相当,体现对学科核心素养的考查,影响试题难度的因素主要有认知水平、思维推理和图样运算三种因素。研究表明:教师要关注基于真实的技术问题情境,建构知识体系,提高学生的电路读图、析图能力,强化技术实践,提升学科核心素养水平,实现教学相长。

Combined with the characteristics of test questions of Technology of Elective Subjects of Zhejiang Province,three sets of elective test questions from November 2018 to January 2020 are analyzed from five dimensions of background factors,cognitive level,thinking reasoning,logical operation and knowledge synthesis,with the help of comprehensive coefficient model.It is found that the overall difficulty of these three sets of test questions is equivalent,which fully reflects the examination of the key competence of the subject.The main factors affecting the difficulty of general technology test questions are cognitive level,thinking reasoning and pattern operation.The study shows that teachers should pay attention to the real situation of technical problems,construction of knowledge system,improvement of students’ability of reading and analyzing circuit diagrams,strengthening technical practice and key competence level of the subject,and realize the mutual benefit of teaching and learning.
