IMPACT OF SAVI APPROACH TO IMPROVE STUDENT ACHIEVEMENT ON TEN GRADE STUDENTS AT SMA NEGERI 1 AIR JOMAN

ABSTRACTThis study aims to investigate the impact from application of SAVI (Somatic, auditory, visual and intellectual) approach to improve student’s mathematics achievement on volume and distance of three dimension material. Quasi experimental method was used in the study. The population of the study were ten grade students of SMA Negeri 1 Air Joman. The samples of this study were 60 students which divided into two groups, experiment group and control group. The 30 students in experimental class were given SAVI approach and 30 students in control class were given conventional approach. The data were collected using a set of test and a set of questionnaire. A set of test was used to measure student’s achievement in learning volume and distance and a set of questionnairewas used to measured student’s attitude toward learning by SAVI approach. Both instruments were validated by expert. Software SPSS was used to analyze the data. The result of this study are: (1) students’ achievement after treatment given is higher than before treatment given both by SAVI approach and conventional approach; (2) the improvement of students’ achievement in SAVI class is better than students’ achievement in conventional class on the subtopic of volume and distance in grade X; (3) students attitude toward mathematics generally show a positive attitude. Keyword : SAVI approach, conventional approach

EFEKTIVITAS PEMBELAJARAN KONTEKSTUAL DITINJAU DARI KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA SISWA SMP NEGERI 1 KISARAN

ABSTRACT Problem solving is one of the skills needed in everyday life. The problems that arise in the life of every human being are very diverse from various fields. Each problem has its own strategy for finding a solution. Problem solving skills can be learned in the learning process. One of the lessons that can train problem-solving skills is learning mathematics. Learning is expected to lead more to the situation or condition of students in their life and can be applied in learning mathematics itself. Learning mathematics in accordance with student problems, students can be more focused in solving mathematical problem solving. One approach that can be applied to bring mathematics learning to students' lives is by using a contextual approach. The purpose of this study is to obtain information about mathematics learning where students are able to complete problem-solving steps through contextual learning. This research was conducted at SMP N 1 Kisaran. From the overall test results above, it was found that 16 out of 24 students (66.7%) had achieved mastery learning (score ≥ 75) while the other 8 students (33.3%) had not yet completed it. The class average score obtained was 69.4. In other words, contextual learning in terms of effective problem solving was implemented in SMP N 1 Kisaran. Keywords: Problem Solving, Contextua

The purpose of this study was to determine the quality of ethnomathematics-oriented student worksheets (LKPD) based on students' mathematical representation abilities produced in this study in terms of valid, practical, and effective criteria that have been set. This type of research is research and development (R&D), namely the development of student worksheets based on ethnomathematics orientated from students' mathematical representation abilities. R&D, namely the development of worksheets developed based on the Plomp model which consists of the initial investigation phase (prelimenary investigation), design (design), realization/construction (realization/construction), test, evaluation and revision (test, evaluation, and revision). The test subjects in this study were class VII-4 students of SMP Negeri 1 Tanjungbalai Asahan. Based on the results of the trials carried out, data obtained from the validation results of experts with an average of 93% is in the very valid category, because 81% - 100% so that the LKPD is said to be very valid. Furthermore, student worksheets were assessed by students with an average response of 93% in the very practical category, and the teacher's response with an average response of 90% in the very practical category. So based on the results of the students' mathematical representation ability test they completed classically with an average of 94% in the very effective category

INCREASING OF MATHEMATICHAL PROBLEM SOLVING ABILITIES HIGH SCHOOL STUDENTS THROUGH GUIDED DISCOVERY LEARNING AT SMA NEGERI 1 AIR JOMAN

This type of quasi-experimental research aims to determine the increase in mathematical problem solving that occurs in students who are given guided discovery learning and conventional learning. The population in this study were all students of SMA 1 Air Joman Asahan District with students from two classes X X-2 and X-3 respectively. Students' initial mathematical abilities are classified according to the value of report cards. The instrument used consisted of mathematical problem solving tests. The results showed that increasing of problem solving abilities of students taught with guided discovery learning was higher than the mathematical problem solving abilities of students taught with conventional learning. This is seen from the N-gain experimental class (using guided discovery learning) of 0.14 and the N-Gain control class (using conventional learning) of 0.13. The interaction between learning and initial abilities is known that these factors do not contribute simultaneously to increasing of mathematical problem solving abilities.Keywords: Guided discovery learning, mathematical problem solving abilities
