Abstract

Student in junior high school frequently erroneously solve multiplicative word problems additively. Students in this stage should be able to solve the multiplicative word problem, how to understand the known and what is asked, what the strategies properly, and how to execute it become the right one. It has close related with student problem solving behavior. Through problem solving behavior given provided description of the student behavior during the process for solving mathematics problem, especially multiplicative word problem.

The purpose of this study to investigate studentsâ€™ problem solving behavior on solving the multiplicative word problem. This study take place in SMPN 39 Surabaya. Subjects in this study were 7-A^th class from nine 7^th grade. Subjects were given three items test of multiplicative word problem. Three subjects were volunteerly selected based on multiplicative word problems namely solved the tasks multiplicative properly, solved at most one the task multiplicative additively, and solved at least two the tasks multiplicative additively. The three volunteerly students represent each category students that appear when solved the tasks multiplicative word problem, subjects needed for deep interview of students problem solving behavior in solving multiplicative word problem.

The findings of the multiplicative word problem show that there are three category students when solved the task. The problem solving behavior of subject who solved the tasks multiplicative properly (subject 1^st) tend to Meaning Based Approach-justification (MBA-j), the problem solving behavior of subjects who solved exactly one task multiplicative additively (Subject 2^nd) tend to Meaning Based Approach-full context (MBA-fc), and the problem solving behavior of subjects who solved at least two task multiplicative additively (Student 3^rd) tend to Direct Translation Approach-not proficient (DTA-np). Detail aspect for each subject shown in table 1.
