Abstract

This article was a qualitative research type grounded theory. The purpose of this study is to analyse mathematics disposition through vocational high students in order to understand students’ disposition on mathematics deeply. This study belongs to post positivism paradigm research. According to ontological side, the reality about students’ mathematics disposition is actually appear on students but not or have not been understood before, it just predictable. Otherwise, according to epistemological side, the prediction about mathematics disposition is needed to be more understood. That’s way qualitative research is needed to overcome students’ negative mathematics disposition. Researcher as the instrument analyse students’ mathematics wisely with using triangulation of the data. This study was implemented in one of the vocational high school in Bandung, west java. The subject of this study is 27 students of XI grade at SMKF Bumi Sliwangi. Based on analysis of the data, the finding is obtained in this study are: (1) SMKF Bumsil has a complete facilities with fresh air and a clean environment, (2) mathematics studying and learning process in the classroom is very optimal and conducive so that it can give a positive attitude in students’ mathematics disposition, (3) based on result of quationaire data, there are 21 students (78%) have a positive attitude in mathematics disposition, although there are 6 students (22%) have a negative attitude in mathematics disposition. We can conclude that most of students of  XI grade at SMKF Bumsil have a positive attitude in mathematics disposition.

Abstract

The purpose of this study  is to investigate and to describe the gain of students’ mathematical understanding ability through mathematics teaching and learning by using dynamic geometry software, Geogebra. This study uses a not equivalent control group design, that is control group and experiment group. Direct instruction is implemented in control group otherwise mathematics teaching and learning with using Geogebra is implemented in experiment group. The population of this study are allof junior high school students, the subject are two groups of seventh grade students and the object is studentss’ mathematical understanding ability. The sample is choosed with using purposive sample technique. This study use mathematical understanding ability test that analysed quantitatively into post-test and normalized gain of students’ mathematical understanding ability between the two groups. The analyse of the data result will answer the hypothesis, students’ understandingability who has studied and learntwith using Geogebra is better than students in direct instruction class.

Abstract

This article aims to examine the interaction between improving students’ creative thinking ability toward the learning approach that is the End-Ended Approach and Conventional Learning and Mathematical Early Skills (KAM) of the students. The research was conducted in one of State Junior High School with population of all students of class VIII. Two classes were selected from the population as a sample of the research using purposive sampling technique. Conventional Learning is implemented in the control class and the Open-Ended approach is implemented in the experimental class. This research uses the instrument of creative thinking ability test to see the improvement of students’ creative thinking ability. The data processing of students’ creative thinking ability based on mathematical early ability (KAM) is done by using two–way ANOVA test at 5% significance level (α = 0,05). followed by Post Hoc LSD test. Based on data analysis result, it is obtained: (1) there is a difference  of improvement of creative thinking ability between students who gain learning by using Open-Ended approach with  students who abtained Conventional Learning from the Mathematicsl Beginning Skill (KAM) of students; (2) there is no interaction between the learning approaches (Open-Ended and Conventional) and students’ Mathematical Abilities (high, medium, and low) towards improving students’ creative thinking ability; (3) students show positive attitudes toward the Open Ended approach. This study  is a learning factor and theoretical ability of the students does not provide the same effect on the students’ creative thinking ability.

Abstract

This study used quantitative approach with experiment method. The research design was posttest-only control group. The purpose of this study was to investigate the effect of cooperative learning model type Student Facilitator and Eksplaining (SFE) with poster media through students’ mathematical representation ability. The population was all of seventh grade students in SMPN 7 Sungai Penuh. Two sample were choosen withdraw. Conventional method was implemented in control group, while cooperative learning model type Student Facilitator and Eksplaining (SFE) with poster media was implemented in experiment group. The instrument in this study was students’ mathematical representation ability test that the test items was analyzed first. The instrument was given in the end of learning process in both groups. The result of the data analysis was obtained that: (1) the average of students’ mathematical representation ability test in control group was 66,67 while in experiment group was 73,43; (2) the students’ mathematical representation ability who study under cooperative learning model type Student Facilitator and Eksplaining (SFE) with poster media was higher than who study under conventional method; (3) there was an effect of cooperative learning model type Student Facilitator and Eksplaining (SFE) with poster media through the students’ mathematical representation ability.

Abstract

This research was started by the lowerness of students’ mathematical reasoning ability at VII grade of SMPN 1 Kerinci. That’s obtained from the student’s semester examination result then according to the experience, observation and interview results with the junior high school mathematic teachers. The aim of this research is to analyze the effect of Problem Based Instruction (PBI) Model through student’s reasioning ability at VII grade of SMPN 1 Kerinci. This research is using quasy experiment method with Randomized Group Control Only Design. The population is all of seventh grade students in SMPN 1 Kerinci. This research is using Random Sampling Technique that students at VII-C grade as experimental group and VII-A grade as control group. The research instruments in this study is mathematical reasoning ability test to obtain students mathematical reasoning ability. The data is not have normal distribution so that we used Mann Whitney-U test with SPSS helped, obtained Sig (1-tailed). value = 0,000 α = 0,05 so that rejected H0. According to the analyzed of the data, the conclusion obtained that student’s mathematical reasoning ability who learn with using PBI Model is better than using conventional learning.

Abstract

This study aimed to determine students' critical thinking skills on the subject of number patterns using the Blended Learning learning model. The research was conducted at MTsN 3 Kerinci, Academic Year 2021/2022. The research method used is a quasi-experimental method with a posttest-only control design. The research instrument used is a critical thinking ability test. The results showed that the critical thinking ability of students who were taught with the Blended Learning leraning model assisted by video tutorials had an average score of 8.58, and the class that did not use the Blended Learning learning model assisted by video tutorials had an average score of 6.24. Thus, this study concludes that the Blended Learning learning model has a significant influence on students' critical thinking ability.
