<![CDATA[Communication skills focus on the importance of speaking, writing, describing and explaining mathematical concepts. In achieving that success is by using cooperative learning model. This model is an effective teaching strategy in improving student achievement and socialization while contributed to their changing of attitudes and perceptions of the importance of learning and cooperation, including for their understanding of their peers from different ethnic backgrounds. This research was conducted at SD IT Faza Azkia Kelurahan Hutaraja, South Tapanuli Regency, North Sumatera Province. This research uses quasi experimental research method. This study aims to describe how to improve students 'mathematical communication skills before and after using cooperative learning model, and also to know the effectiveness of using cooperative learning model in improving students' mathematical communication ability. Based on the results of the study concluded there is an increase in the mathematical communication skills of students before and after using cooperative learning model. And the cooperative learning model is effective for teaching count number operations. This is shown by: the effectiveness of student learning activities, the ability of teachers in managing learning is effective, students 'responses to learning is positive and mastery of students' mathematical communication skills reach 100%.]]>

<![CDATA[This study aims to determine the increase in the understanding of concepts and students ability at SMP Swasta Tarbiyah Islamiyah for the cube and beam through mathematical realistic approach. To find out how much improvement is obtained, students were given a test of understanding of concepts ability. Increased capabilities were first analyzed by using the normalized gain and processed by using two ways ANOVA formula. Two ways ANOVA formula is also used to determine whether an interaction between learning approach and students abilitiy to increase understanding of concepts skills. The results showed that (1) an increase in the understanding of concepts that students taught through mathematical realistic approach higher than understanding of concepts ability that students are taught only through ordinary learning, and (2) there is no interaction between the learning approach and the students ability to the improvement of students 'mathematical understanding of concepts ability.]]>

<![CDATA[The Problem in this research is lower capability of problem solving mathematical of students is the result of expository learning who did not considering multiple intelligences (multiple intelligence). The Purpose of this research was aimed to the improvement of mathematical problem solving capability and the interaction of KAM and learning factor toward the improvement problem solving capability. The type of this research is quasi-experiment research, subject of this research is VIII grade SMP Budisatrya Medan and sample selected by purposive sampling method. The subject of this research is divided into 2 class, first class is given cooperative learning based on multiple intelligence and the second class that given regular learning or expository learning. To measure the student’s capability that use the instrument that has been validated by 8 expert and already tested that showed the results of reliability question (0,946) for KAM and (0,905) for problem solving capability test. Data analysis was performed with ANOVA two lanes factorial. Based on the research results can be concluded that an increase in the ability of students' mathematical problem solving through cooperative learning based on multiple intelligence higher that regular learning and there is no interaction between prior knowledge of mathematics to increase the ability of solving problem mathematical.]]>

<![CDATA[This study aims to find out how to improve the results of mathematics learning on the subject of summing in integers through Buzz Group method along with media Kelereng on the students of class I SD Negeri 020580 Binjai. And how the creativity and ability of teachers in implementing learning in the classroom. The result of this research concludes that the result of student learning in learning through Buzz Group method is On cycle I the good categorization value reaches only 20%. That means that a small part of the first cycle is more increased than before the improvement of learning. Nevertheless, the less categorized students are still in the most process that is 40% and the categorized is as much as 40% that finally in the second cycle the number of students who are categorized moderate and less should decrease. In cycle II, good categorized value is much more and melngalami significant achievement increase that reaches 80%. then the students who get the category is 20%. After the main problems in the improvement of learning on the cycle I and II implemented, the authors were satisfied with the increase in student value on the implementation of improvement learning in cycle II seen in the moderate category decreased and the absence of students who got less value]]>
