Abstract

Creativity could be interpreted as a person's cognitive abilities in solving problems by bringing up new ideas. The problems of students’ math achievement lows are math presented as a finished product, ready to use, abstract and taught mechanistically. This case can be lead to the creativity of the less developed students because students are not given the opportunity to think and use their ideas in solving mathematical problems. Problem Based Learning Model is a learning model that emphasizes the concept and information outlined from the academic discipline. The purpose of this study is to analyzed students’ creativity in solving mathematical problems through Problem Based Learning model (PBL) in class VIII-1 MTsN Model Banda Aceh. Data gained based on the students’ worksheet in groups. The data acquisition is categorized into 5 levels (highest level 4 and lowest level 0) which is analyzed descriptively. The results are three groups were at level 4 with very creative categories, one group is at level 3 with a creative category and another group is at level 2 with deeply creative enough category. To the conclusion is PBL model could cultivate the students’ creativity in solving mathematical problems.

Abstract

Indonesia is an archipelagic country lies on the Pacific Ring of Fire, resulting in the country being vulnerable to disaster. Teachers need to accustom students to manage natural disaster situation in a more logical approach. Therefore, it is necessary to develop mathematical problems in disaster contexts. This research is an early stage of developmental research. The purpose of this study was to analyze the needs of teachers and students of mathematical problems in disaster contexts. The participants in this study were a mathematics teacher and 53 Year 7 and 8 students at one of the public junior high school, located in a Tsunami affected area, in Banda Aceh. Data collection involved an open questionnaire, and data analysis was carried out descriptively. The results showed that the teacher often provided mathematical problems in learning but had never read mathematical problems in disaster contexts. Also, only three students had ever read such problems. The results also revealed that nearly half of the students (41.5%) liked to solve mathematical problems. Besides, both the teacher and 71.7% of the students agreed and were willing to participate in the learning process involving mathematical problems in disaster contexts. The results of the study also showed that the mathematical questions in disaster contexts were limited. Thus, it is necessary to develop mathematical problems in disaster contexts.
