Abstract

The purpose of this research is to consider the benefit of applying GeoGebra interactive media to improve student achievement in learning derivatives. This study was experimental research using counterbalance design. The population of the study was four classes of grade XI students of SMA Negeri 3 Jayapura academic year 2018/2019 consisting of 122 students. Purposive sampling was applied in this study to get two experimental classes with the number of students were 22 and 26 respectively. In both experimental groups received the same treatment which were learning using GeoGebra interactive media and learning without using GeoGebra interactive media which applied orderly. This process was implemented four times at both classes interchangeably. The data of the study was collected from participant’s pretest and posttest at every learning treatment. Data was analyzed using Wilcoxon Signed test with the significance level (two-tailed) of 0.05. The result of the study shows that there are significant differences in learning outcomes of the two types of learning. The learning process which was designed using GeoGebra interactive media obtained the superior learning outcomes.

Abstract

This study aims to evaluate the strengths and weaknesses of teachers in the teaching process in terms of aspects of mathematics teacher competency. It describes how the four teacher competencies have been running in the learning process in the classroom based on students' perceptions related to student competencies themselves using Structural Equation Modeling data analysis techniques (SEM). The study population was all junior high school students in Merauke City, Papua. The method of sampling was used proportional random sampling, which is continued by simple random sampling, to obtain a total sample of 436 students. The data collection was carried out by distributing questionnaires to students' perceptions about the performance of mathematics teachers consisting of 48 questions in the form of a Likert scale. The results obtained that pedagogic and social competencies are competencies that affect student competencies with mathematics teacher pedagogical competence is most influential on student competencies. Therefore, to improve student competency, teachers need to improve pedagogical and social competence.

Abstract

The purpose of this research’s to analyze students interest in mathematical leaning by the matery Grafik Fungsi Kuadrat (Graphs of Quadratic Functions) assisted by GeoGebra sofware. In this research, the researcher used descriptive research method, descriptive research method is the research that generates descriptive data through the percentage of student answers that contain 5 indicators of learning interest scale students by given poll. The population of this research were 28 students of  nineth grade of SMP Bingkai Cendikia Cililin. Research data were collected by using the scale of learning interest of students in GeoGebra sofware assisted with mathematics learning that contains 20 questions each 10 positive and negative questions. The result of the data analysis could be concluded that there is a positive impact on students interest in learning mathematics assisted with GeoGebra sofware. The result of the data analysis showed by the average percentage of answers of students who agree of positive statement’s 49%, then the response of agree average of 67%, and then disagree response’s 10,8%, while for strongly disagreeing responses of 6.5%.

Abstract

This Qualitative study aimed to describe the students the mistakes in solving the problems related to cubes and cuboid topics based on Newmann's procedures. To gather the data, three students of primary school teacher department in a university in Kupang, Indonesia, with a high, moderate and low problem – solving skills were chosen to be analyzed further using descriptive method. The result showed that the students with a high problem – solving skill were doing wrong in writing the final answer due to an incomplete understanding of cube and cuboid. The students with a moderate problem – solving skill were doing mistake in transforming the word problems into mathematical expression since the students were not accustomed to do non – routine problem. Furthermore, the students with the low problem – solving skills were doing mistakes in transforming word problems into a mathematical expression, during the process and writing the final answer. The mistake was emerged due to students’ inability to understand the problems and incomplete understanding of the concept of cube and cuboid.

Abstract

This study aimed to reveal how the Manggarai community used mathematical concepts in making the traditional house (Mbaru Niang) roof of Manggarai people and what were the mathematical concepts contained in it. This research used a qualitative approach with ethnographic methods. The selection of subjects in this study used purposive sampling technique. Data obtained by interviewing, observing and documenting. The validity of the data is supported through theory and facts in the field and also through expert judgment. The results showed that in the stages of the process of making the traditional house roof of Manggarai there were 3 activities that had a mathematical nuance namely designing, numerating and measuring and the mathematical concepts contained in the traditional house roof were the concept of the shapes namely triangles, rectangles, trapezoid and circles, the concept of distance, the concept of parallel lines, and lines and the pyramid.

Abstract

The study aims to identify kinds of high school students’ misrepresent in doing their tasks and to provide the appropriate scaffolding as a solution to help the students. This is a qualitative descriptive research. The research subject consists of three junior high school students who have different abilities in Mathematics. They were selected out of 92 students. This research studied the conceptual errors, procedural mistakes, and students’ technical mistakes in working on the problems based on the stages of Kastolan mistakes and the scaffoldings given. Furthermore, the data were collected by using the way of testing, interviewing and documenting techniques. The research data were guarantee validated with the triangulation method. The result of the research showed that there were some errors done by the students in doing the tasks. They were the conceptual errors, procedural mistakes, and technical errors. The scaffoldings given to help the students do the tasks for Level 1 (environmental provisions), Level 2 (explaining, reviewing dan restructuring), and Level 3 (developing conceptual thinking).

Abstract

This study aims to describe students' mistakes in solving rectangular problems based on their cognitive development. This research is a descriptive qualitative study with 4 research’s subjects taken based on purposive sampling. Data collection techniques use tests, namely Test of Logical Operations and Problem-solving Tests. Data analysis techniques include reduction, presentation, and data verification. The results of the study show that mistakes that are often made by students are less complete in writing what is known and asked about the problem. At the stage of devising a plan, students are wrong in determining the formula, the complete steps to be used, and do not write an answer. At the stage of carrying out the plan, students tend to immediately calculate what is known in the problem, not even writing answers at all. Students do not check the answer so that the results of their conclusions and conclusions are wrong.
