ANALYSIS OF MATHEMATIC REPRESENTATION ABILITY OF JUNIOR HIGH SCHOOL STUDENTS IN THE IMPLEMENTATION OF GUIDED INQUIRY LEARNING Yumiati Yumiati; Mery Noviyanti
Jurnal Infinity Vol 6, No 2 (2017): VOLUME 6 NUMBER 2, INFINITY
Publisher : IKIP Siliwangi and I-MES

The objective of this research is to analysing the different on upgrade the student’s math representation that obtained the guided inquiry learning and conventional learning. This research conducted by applying experiment method with nonequivalent control group design at one school. Which becoming research subject are students of Dharma Karya UT Middle School at 8th Grade. 8-2 class selected as control class (19 students) and 8-3 class selected as experiment class (20 students). Before and after learning process, two classes given the test of math representation with reliability is 0.70 (high category). The magnitude of the increasing in students’ math representation student group of guided inquiry learning group is 0.41 included as medium category. Meanwhile, the increasing students’ math representation student group of conventional learning is 0.26 included as low category. In conclusion, the hypothesis of the ability of the mathematical representation of students who learning with guided inquiry is better than students with conventional learning is accepted.

ANALYSIS OF DIDACTICAL CONTRACTS ON TEACHING MATHEMATICS: A DESIGN EXPERIMENT ON A LESSON OF NEGATIVE INTEGERS OPERATIONS Nyiayu Fahriza Fuadiah; Didi Suryadi; Turmudi Turmudi
Jurnal Infinity Vol 6, No 2 (2017): VOLUME 6 NUMBER 2, INFINITY
Publisher : IKIP Siliwangi and I-MES

This paper presents an analysis of mathematical teaching that takes place in the classroom to identifying the characteristics of didactical contract that occur as part of a didactical situation. Didactical contract is a way that determines the responsibilities of teachers and students and regulates their interaction in a learning process. Arithmetic operations involving negative numbers are known to have epistemological obstacles that cause student difficulties in solving problems and understand the higher level subject matter. The design experiment was conducted on 31 seventh grade students and a mathematics teacher on negative integer operations lessons. The researchers analyzed the ongoing learning, how the didactic situational stages evolve in the teacher-student interaction that allows the formation of new knowledge or concepts in the student and how the teacher organizes the responsibility for achieving the learning objectives. The Analysis showed that students, at an early stage, can perform negative integers operations by utilizing the basic concepts they get in primary school. This concept can bridge into a new knowledge that identifies the properties of integer count operations and builds power of mind on problem-solving.

Publisher : IKIP Siliwangi and I-MES

This study is aimed to examine the quality of quantum learning imfluence toward the enhancement of mathematical problem solving ability of Senior High School students, both viewed entirely and based on mathematical initial ability (MIA) category. In particular, this study is aimed to examine enhancement difference of students’ mathematical problem solving ability in a whole and in each level of mathematical initial ability (high, medium and low) between students who receive quantum learning and students who receive conventional learning. This study use experimental quasi with pretests-posttest control group design. Population of this study are Senior High School students in Bogor City. Data is obtained through problem solving ability test and mathematical initial ability data. The result of study showed that students who receive quantum learning have enhancement of mathematical problem solving ability which is higher than students who receive conventional learning. There is no difference enhancement of mathematical problem solving ability both entirely and in each level of mathematical initial ability, except for students with high level of initial mathematical ability

LANGUAGE LITERACY AND MATHEMATICS COMPETENCE EFFECT TOWARD WORD PROBLEMS SOLVING Namirah Fatmanissa; Rahmat Sagara
Jurnal Infinity Vol 6, No 2 (2017): VOLUME 6 NUMBER 2, INFINITY
Publisher : IKIP Siliwangi and I-MES

This study aims to know the effect of language literacy and basic Mathematics competence toward students’ ability to solve word problems. The research was done by giving three sets of questions; language literacy (LL) set, basic Mathematics competence (BM) set, and word problems (WP) set; to the research sample. Research sample was 315 tenth grade students from five schools in Jakarta. Score of students in each set was analyzed as research data. Score of LL set was treated as data of independent variable 1, score of BM set was treated as data of independent variable 2, and score of WP set as data of dependent variable. Preliminary data analyses, such as normality, validity, and reliability test, were done. Then, data was analyzed using Wilcoxon test and calculation of R-square. The result shows that each of independent variable affects dependent variable with BM variable has more effect on WP variable.

Jurnal Infinity Vol 5, No 2 (2016): Volume 5 Number 2, Infinity
Publisher : IKIP Siliwangi and I-MES

This research aims to explore the differences among self regulating learning aspect of math education students-FKIP Undana involving three groups of students which are the first level (the first semester), second level (fifth semester) and third level (ninth semesters) students to review the ability of the individual. The samples included 167 students that consist of 60 students of the first level (18 with high ability; 27 with average ability and 15 with low ability), 64 students of the second level (16 with high ability, 30 with average ability and 18 with low ability) and 43 students of the third level (6 with high ability, 24 with average ability and 13 with low ability). This research is a survey research. The data collection is done by distributing questionnaires on self-regulated learning to those three groups. SRL questionnaire consists of 10 aspects, goal setting, motivation, learning difficulties analysis, self-efficacy, election strategies, meta cognition, resource management, performance evaluation, evaluation of the understanding, and self-satisfaction. Two-way ANOVA was utilized in the data analysis of this study. The results of the analysis showed that, the first level group is more excellent in SRL than two other levels. In a review of capabilities, the average comparison of all three groups showed that the average-ability students excel both the high and low-ability students in SRL.

Jurnal Infinity Vol 7, No 1 (2018): Volume 7 Number 1, INFINITY
Publisher : IKIP Siliwangi and I-MES

This study aims to describe and compare the effectiveness of the application of STAD and TPS types in cooperative learning to the students. This study was a quasi-experiments research in which students were designed into a form of the experimental group (pre-test and post-test group designs), where the cooperative learning of STAD and TPS types will be applied in learning mathematics. The population in this study were junior high school students in Ternate, while samples were taken by 60 random students who had the same characteristics as the population. The result of the study shows that cooperative learning model of both STAD and TPS types are very effective to be applied on studying mathematics. However, between the STAD and TPS types of cooperative learning, the STAD types are more effective than TPS, seen from accomplishing standards of competence, mathematical communication skills, and mathematical thinking ability of Junior High School students.
