Every student must have and develop spatial abilities to be successfull in learning geometry. The rapid development of technology also allows teachers to use macromedia flash as an alternative in developing and improving students' spatial abilities. This study aimed to determine and describe the improvement of the students' spatial ability after getting geometry material by using macromedia flash at MTsN Model Banda Aceh. This research used a quantitative approach with a quasi-experimental design and one group pretest posttest design. The population of this study was all students of class VIII MTsN Model Banda Aceh with random sampling as the sample selection techniques so that the selected sample was the students of class VIII-5. The data collection in this study was carried out using a spatial ability test consisted of pretest and posttest questions. The gained data were analyzed with SPSS version 17 with paired sample t-test and percentage. The results showed that there was an improvement in students' spatial ability after having geometry material learning by using macromedia flash at MTsN Model Banda Aceh. Besides, the improvement of students' spatial ability based on indicator of perception spatial was 61.1%, mental rotation indicator was 55.6%, and indicator of visualization spatial was 66.7%.

This study is motivated by the issues found in observations at school, where the daily teaching activities carried out by teachers show that; teaching and learning activities are classical, the teacher only stands or sits in front of the class, the direct relationship between the teacher and students is rare, and students tend to behave passively, such as coming, listening, reading and writing. To overcome this issues, the researchers conducted a research by applying a three-step type of cooperative learning model interview in learning mathematics in the class. The purpose of this study is to reveal the activities and learning outcomes of students after applying the three-step interview type cooperative learning model. From the results of the study it was found that the learning activities of students during the application of the three step interview cooperative learning model increased at each meeting. Thus it can be concluded that the mathematics learning outcomes of students with learning by applying a three-step interview type cooperative learning model is better than those who do not apply the techniques.

Students’ creativity and self-efficacy in solving mathematical problems remain low. Students with Field Dependent (FD) and Field Independent (FI) cognitive styleshave different creativity and self-efficacy. One learning model that is believed to increase students' creativity and self-efficacyis Problem Based Learning (PBL) model. This study aimed to increase the creativity and self-efficacyof FD and FI students through the application of PBLmodel. This research is an experimental study with pre-test and post-test control group design.The population of this research was grade VIII students in State Islamic School (MTsN) 1 Banda Aceh,while the sample consisted of two classes out of 11 classes. The sampling technique usedrandom samplingwith one experimental class and one control class. Data collection was carried out by using two instruments; a paper-test to measure students’ creativity and a questionnaire to measure students’self-efficacy. The grouping of FD and FI students was based on the results of the Group Embedded Figure Test (GEFT). Furthermore, a paired t-test was conducted to obtain an increase in students' creativity and self-efficacy. At the same time, a correlation test was performed to see the relationship between creativity and the self-efficacy ofstudents. The results of the study revealed that the increase of FD and FI students’ creativity who were taught by the PBL model was better than students taught by conventional methods. The results also reported that the increase of FD and FI students’ self-efficacy who were taught with the PBL model was better than the students who were taught with conventional methods. In addition, there was a significant relationship between FI and FD students' creativity and self-efficacy.

Geometry is one of the topics that students must comprehend in mathematics. However, in reality, the students' ability concerning geometry is relatively low due to their low spatial reasoning ability. The ELPSA framework is one of the solutions to develop students' spatial reasoning abilities. This study aimed to describe students' spatial reasoning ability and the impact on retention through the ELPSA framework. This research was part of the ELPSA framework research and development. The subjects were four students, chosen from 25 Grade 7 students from one of the junior high schools in Banda Aceh. They were selected based on the percentage of spatial reasoning aspects mastered. The instrument used was a semi-structured interview that was preceded by a written test. The results showed that the four subjects could manipulate objects in their mind to change the shape of D-3 to D-2. However, one of them could not determine its relation precisely. Three out of four subjects could imagine the appearance of an object from different perspectives. Besides, two out of four subjects could visualize objects to determine the number of unit cubes contained in the solid geometry and only one subject could imagine objects from various perspectives to determine the surface area but did not use the given measurement.

Mathematics is a human creation, which has been developing for more than four thousand years. It emerged as a response to different social and economic needs of civilizations. Historical development of mathematics stresses that mathematics as a science has always been connected to economic and social context and development of society. There is little or no research that promotes using historical content in mathematics lessons in the Nigeria context. In this paper, we model the use of history of mathematical thought (HMT) in mathematics instruction and solved the formulated model equation using integrating factor. The rate at which HMT is used by teachers in mathematics instruction is assumed to be proportional to the number of teachers that do not use HMT. The analysis suggests that with time, only a fraction of teachers can use HMT in teaching mathematics due to the fact that they will not remember to use it, and additional recruitment of teachers will result in only marginal improvement in the usage of HMT.
