Abstract

This study aimed to improve students’ problem-solving skills and to describe the implementation of creative problem solving (CPS) model in Mathematics Education students of the Muhammadiyah University of Makassar in its program. This research was a classroom action research which involved 33 students with two cycles (1 cycle was 4 times meeting). The cycling stage consisted of planning, action, observation, reflection. Data collection through observation, test result, and student response were analyzed by quantitative descriptive analysis technique. The research finding was: Implementation of learning model (CPS) can improve students’ problem-solving ability which can be seen from the increasing of solving ability from 63,03 (enough) to 77,72 (high). Effective learning (CPS) implementation with learning implementation indicators improved from less category to excellent category; student activeness increased from active category to highly active category, and student responses were in a very positive category. (2) Implementation of Learning Model (CPS) can be implemented through five stages: clarification of the problem; disclosure of ideas; evaluation; and implementation. Keyword: Learning Model, Creative Problem Solving (CPS), and Problem Solving Ability.

Abstract

The main purpose of this study is to describe the errors and causes of student errors in solving math story problems with a two-variable linear equation system based on the Newman procedure. This type of research is a descriptive study with a qualitative approach which was carried out at SMP Negeri 3 Salomekko. The subjects of this study consisted of 3 people who were taken each 1 student with low ability, medium ability and high ability. Data collection techniques used test and interview methods, and instrument validation was carried out with 2 expert validation stages. Technical data analysis using descriptive analysis and qualitative data analysis starting from data reduction, data presentation and drawing conclusions. From the results of the study, it was concluded that high-ability subjects made misunderstandings and errors in writing the final answer. Subjects who are capable of making transformation errors, process skill errors and writing errors in the final answer. Low-ability subjects made reading errors, understanding errors, transformation errors, process skills errors and writing errors in the final answer. The causes of student errors are 1) reading errors are caused by haste and confusion in interpreting the meaning of the word. 2) misunderstandings are caused by lack of knowledge in interpreting the meaning of words and forgetting. 3) the transformation error is caused by not understanding the problem and being confused about working on the problem. 4) process skill errors are caused by lack of thoroughness and haste. 5) the error in writing the final answer is caused by lack of thoroughness, haste, and did not find the final result.  Keyword: Student errors, Solving math story problems, Newman procedure
