Abstract

Mathematical achievement in problem solving is not yet as expected. This is due to strategies that have not accommodated the situation of students.  Adversity quontient is the state of the student who needs to get the attention of the teacher so that the learning strategy is expected to be appropriate. This research aims to describe the thinking process of MTs Darul Hikmah students in solving mathematical problems in build side spaces of material reviewed from adversity quotient. This research is in the form of qualitative. The subject selection was done by giving questionnaires to class VIII MTsS Darul Hikmah students and obtained by each one person from each adversity quotient group. The subjects in this study amounted to two students. Data collection is done through tests and interviews, while data analysis uses qualitative data analysis techniques, namely data reduction, data display and conclusions from each adversity quotient group. The results showed that no class VIII students entered the quitters group and the results of the study also showed that class VIII students consisted of climpers and campers. The process of thinking of MTsS Darul Hikmah students based on adversity quotient varied: students in the climbers category namely 3 of 53 students had conceptual thinking processes, while students in the campers category were 27 of 53 students did not have conceptual, semiceptual, or computational thinking processes.

Abstract

Interest geometry are taught is to develop spatial ability so as to impart knowledge to support other materials. As NCTM specify one of five content standards in mathematics, namely geometry measurement an important element involves the use of visualization and modeling. This shows that modeling is the demands of the curriculum that must be accommodated in the classroom. Therefore, teachers should be able to apply the learning object model that abstracts from geometry into real situations imaginable learners. One lesson that applies the use of models that help learners build their own knowledge is Realistic Mathematics Education (RME). Shaped media selection Information and Computer Technology (ICT) can also meet the demands of the curriculum on the use of visualization to teach geometry. One of ICTs to facilitate learners to imagine something abstract geometry of the object is Cabri 3D software. But in reality there is no learning device that integrates Cabri 3D geometry once using RME approach. This study aims to develop and produce devices RME-assisted learning Cabri 3D is valid, practical, and effective. This research is a research development refers to the model of Dick and Carey consisting of nine steps, namely the identification of learning objectives, learning analysis, identification of the characteristics of learners, formulate learning objectives, develop test items, develop learning strategies, develop learning materials, design and implement formative evaluation, and revising instructional materials. The trial in this study conducted in SMP 19 Pilot Banda Aceh. The result showed that the learning device geometry with Cabri 3D-assisted RME approach memenui valid criteria, practical andeffective.
