현행 중등학교 과학 교과 지필평가 문항분석

Abstract

The purpose of this study is to analyze paper and pencil test items of current secondary school science. We investigated by using modified item classification framework, and yielded item difficulty(P), discrimination index(DI) and reliability(Cronbach α) by applying the classific test theory, and classified students' test score distribution type.The findings of this study are as follows: (1) In item making trend, the proportion of knowledge domain is much higher than inquiry process domain. Most of items are composed of textual context. For the most part, items are represented by using picture or text, while graph and table is rarely used. Item type and form is various according to school. (2) In case of P and DI, the greater part of items are made easily, and DI is farly high. The proportion of satisfactory item of short answer/essay type is higher than that of multiple choice type. There is big difference between teacher and student in P perception. (3) As a whole, reliability of eight school are satisfactory. In classification of students' test score distribution type, we recognize three distribution types(positive, bimodal, and negative). We inferred that item difficulty and regional characteristics influence to distribution type.Accordingly, to improve the quality of paper and pencil test items of current secondary school science, teachers need to use various item representation and elements of inquiry process domain impartially, and reduce the proportion of easy item. As well, teachers should be more careful in making multiple choice item and its allotment.
