Abstract

The ability to solve problems is one of the 21st-century skills that students master. In school, there are various cognitive styles in solving math problems. So it is necessary to describe the problem-solving skills of students of State Junior High School (SMP Negeri) 3 Kasihan Bantul class VIII in terms of the cognitive style of field-dependent (FD) and field independent (FI) of the academic year 2017/2018.  This research is qualitative descriptive research. The subject of research consists of 2 students whose cognitive style FD and two students cognitive FI style. The instrument used in this research consists of the main instrument that is self-researcher. The auxiliary instruments are Group Embedded Figure Test (GEFT) and Problem Solving Testing (TKPM). For data collection techniques used are GEFT, TKPM, and interviews. To obtain data consistency, used technique triangulation. Data analysis techniques include data reduction, data presentation, and conclusions. The results showed that the subject of FD tends to think globally in solving the problem. Subjects have used three problem-solving indicators: understanding the problem by repeated reading, planning by analyzing, implementing plans that have been prepared to get the results of completion, and drawing conclusions. At the same time, the subject of FI is more analytical in solving the problem. The subject has used three troubleshooting indicators, understood the problem by repeated reading, drafted a settlement plan from the information obtained, executed the plan developed to get the result of completion, and drew conclusions. The subject of FD and FI equally did not re-examine the answer.

Abstract

Development of Mathematics Module Based on ARIAS Model on the Material of Algebraic Form For Junior High School Grade VII 1ST Semester. The problems that were found are limited availability of teaching materials causes the learning process to be less varied and teacher-centered, so the student's independence and activeness in building their knowledge below. This research aims to develop, test the modules' feasibility, and determine student responses to modules with the ARIAS model on algebraic form material. The research design used is Research and Development. The research subject is material experts, media experts, and students from Junior High School (SMP) Muhammadiyah 04 Yogyakarta and SMPN 03 Pleret. Data collection techniques were used through interviews and questionnaires with teachers and students. The instrument was tested through validation from material experts and media experts. Data analysis used questionnaire analysis and analysis of the feasibility of the mathematics module. The results showed that the module's assessment by material experts obtained an average score of 106,33 with very good. The module's assessment by media experts obtained an average score of 131 with thry good. The student's response obtained an average score of 114,83 with the category of very good. Based on the calculations' results, it can be concluded that the mathematics module was feasible to be used in the learning process.

Abstract

The activity of students when lessons in class are still lacking. Some of his students still consider mathematics a difficult subject to understand. The students tend to be passive when the lesson takes place; they just sit back and accept the material presented by the teacher. This study aims to improve students' activeness in learning mathematics using Snowball Throwing (ST) model. This study is a classroom action research consisting of two cycles. The subject of this research is the students of class VIII C SMP Muhammadiyah 3 Yogyakarta academic year 2016/2017. This research aims to increase student activeness in learning mathematics by using the Snowball Throwing model. Data collection techniques include observation, unstructured interviews, and diagnostic tests. The success criterion in this research is marked by the increase in the average student activity percentage of at least 61% or good. The results showed that using the model learning model of Snowball Throwing can improve students' activity in learning mathematics. This is seen as an increase in the percentage of student's activity is 56.32% with sufficient criteria in cycle I and increased in the second cycle of 71.75% with Good criteria.

Abstract

Rapid technological developments, make innovation development of instructional media of mathematics as a tool for learning. Media developed learning because students are still challenging to understand the material system of linear equations, so that the need for renewable innovations in mathematics for students in learning to overcome boredom. The use of laboratory and LCD (Liquid Crystal Display) is still not widely used in learning mathematics. This study aims to develop teaching media in the form of interactive media using Macromedia Flash 8 in the learning of mathematics in SMK on the material of the Two-Variable Linear Equations System and test the feasibility. This study focused on developing mathematics learning media packaged in a Compact Disc (CD). The development of research using (Research and Development). The subject of research is matter experts, media experts, and National Vocational High School Berbah (SMK Nasional Berbah) and Muhammadiyah Vocational High School 3 Yogyakarta (SMK Muhammadiyah 3 Yogyakarta). Learning media is validated by three votes materials experts, three expert media, and the subject of the trial of 10 students on a test smaller classes. All students in the pilot class of high use assessment instruments or sheets instrument quality research materials and instructional media student response. Data analysis techniques use qualitative analysis that is converted into quantitative value. Data collection techniques in the form of interviews, questionnaires, and observations. This research has succeeded in developing a medium of mathematics learning that has quality on every aspect of assessment with an average score of 76,67 material experts with good criteria and an average score of expert media assessment 40,33 with Very Good criteria. While the score of student response 69,74 with the score on the small class test and big class test with good criterion. Based on these assessments, this math learning media is worthy of being used as a learning resource for students.
