<![CDATA[ABSTRACTThe purpose of this study was to improve the activities and learning outcomes of the subject matter of statistics in SMAN 7 Bengkulu city. Student learning outcomes regarding the subject matter of statistics still have not reached KKM, which is 75. This is because some students still consider that mathematics lessons are boring. Therefore, the researchers concluded that the learning process carried out must have variations to improve student learning activities through the application of the Student Teams Achievement Division learning model. This research is a classroom action research carried out in several cycles. Each cycle consists of four stages, namely planning, implementing actions, observing and reflecting. The study was conducted in SMAN 7 Bengkulu city with the research subjects being students of class XII IPA 5. Data collection techniques carried out in this study were observation and test of learning outcomes. The instruments used are student observation sheets and test questions. The indicator of success used is the activity of students said to increase if the results of observations of student activeness in general achieve active, ie achieving a score between 24-30 and completeness of learning in a classical manner will be achieved if 75% of students get a value of ≥75. Based on the results of the study, it was found that the mathematics learning outcomes of class XII IPA 5 students of SMA N 7 Bengkulu City increased with the application of the learning model of the student teams achievement division. This can be seen based on the results of the final test of each cycle, namely the average value in the first cycle is 71.77 with classical learning completeness 43.33%, in the second cycle increased to 76.64 with classical learning completeness 60.61%, and at cycle III increased to 83.24 with classical learning completeness 82.35%. Keywords:Model Student Teams Achievement Divis ]]>

<![CDATA[The purpose of this study is to see and explain the potential application of local cultural values to the learning process in elementary schools. Problems that occur based on the results of observations that many students have difficulty in understanding mathematical concepts, so that it will affect student learning outcomes. The method in this research uses the type of case study research. The sample of this study was 3 (three) elementary schools in Jakarta. Some types of local culture that are applied consist of 2 (two) types, namely Textual and Building. The results of the study were conducted in several schools, namely the Mathematics learning process using local culture-based learning models such as doorstop learning models and teachers using media and local culture-based teaching aids such as miniature Betawi traditional houses. By integrating Local Wisdom in Mathematics learning, mathematical objects that exist in the human mind, in the form of facts, concepts, principles, and skills will emerge so as to strengthen the ability of understanding, reasoning, creative, critical, and communicative in solving mathematical problems faced by students.Keywords: Local Cultural Values; Mathematics Learning]]>

<![CDATA[ABSTRACTThe purpose of this study is to determine whether there is a difference in the ability to understand the mathematical problems of students through the VAK learning model using VCD and print learning media. This type of research is an experiment using pretest-posttest control design. The sample of this study were three classes, 2 experimental classes and 1 control class. The results showed that the average value of student learning outcomes through the VAK learning model using VCD learning media in the initial test was 46.31 while in the final test it was 83.56; the average value of student learning outcomes through the VAK learning model using print learning media (LKS) in the initial test of 37.31 while in the final test amounted to 72.21; and the average value of student learning outcomes through the conventional VAK learning model in the initial test was 45.34 while the final test was 55.5. The results of the values of these three classes were tested statistically using One way Anava at significant (α = 5%) to determine whether there were differences. From the results of the one way anava test there was a significant difference between the VAK learning model using VCD learning media, the VAK learning model using printed learning media (LKS), and conventional learning models. Keywords: Visualization, Auditory, Kinesthetic (VAK) Learning Models, Mathematical Problem Solving Capabilities, VCD Learning Media]]>
