Mathematical Modeling Skills on Solving PISA Problems

2018 
This study aimed to describe the mathematical modeling skills of students on solving PISA problems. Participant consisted of 40 students in class VIII-1 SMP Negeri 13 Palembang. Data collection techniques was a test to determine students' modeling skills, and interview. Results of tests and interviews were analyzed based on indicators of mathematical modeling skills as follows: (1) Formulate, (2) Employ, (3) Interpret. Results showed that: (1) For indicator 1the students in good category, the students can identified the significant variables in problems or situation, while in enough category can't use the variables, and then the students in bad category, the students can't identified and used the variables, (2) For indicator 2 the students in good category, the students can employed concept, fact, procedure and reasoning. In enough category, the students employed concept and fact but can't employed procedure and reasoning. In bad category the students can't employed concept, fact, procedure, and reasoning. (3) For indicator 3 the students in good category, the students can reflected solutions, result and conclusion. In enough category, the students can reflected solution and result, but didn't give conclusion. While in bad category, the students can't reflected solution, result, and conclusion.
