An Analysis of the Addition and Subtraction of Fractions in Elementary Mathematics Instruction Materials Based on the 2007 Revised and 2009 Revised Curriculum

This paper analyzed the instructional materials developed under the 2007 revised and 2009 revised curriculum regarding the addition and subtraction of fractions in various aspects. Firstly, we examined the connection between the curriculum and its concomitant textbooks, followed by the appropriateness of learning sequences and topics. We then analyzed in detail the textbooks and workbooks according to the main instructional flow: introduction, activity, and exercise. Regarding the introduction, we analyzed the meanings of fractions and operations in word problems. Regarding the activity, we examined the diversity and appropriateness of visual models, and explored how the algorithms of the addition and subtraction of fractions were drawn from the activity. Finally, regarding the exercise, we analyzed the types of problems in the textbooks and workbooks, and the types of responses required to students. As such, this paper is expected to provide suggestions for the development of textbooks and workbooks of the 2015 revised curriculum.
