Abstract

The purposes of this development research to develop interactive multimedia-based learning media Pilar Baru (Pintar Belajar Bangun Ruang) and describe the quality of media based on aspects of validity, practicality, and effectiveness. The design of this study refers to the ADDIE development model which includes 5 stages, namely analysis, design, development, implementation, and evaluation. The research instruments were in the form of media assessment sheets by material experts, media experts, and teachers to measure practicality. and learning outcomes test questions to measure media effectiveness. Product testing was conducted on 36 students of class VIII. The results showed that the assessment by the material and media experts was obtained an average score 4.29 then the teacher obtained an average score of 4.4 with very good criteria so that the developed media was declared valid. The results of the questionnaire response analysis of students obtained an average score of 4.57 and the teacher's response obtained an average score of 4.62 with very good criteria. The results of observations of the implementation of learning showed a very good classification with a percentage reaching 96.87%. The percentage of classical completeness from student learning outcomes tests reached 80.6% so the media was declared effective.

Abstract

This is a qualitativedescriptive research that aims to analyze the application of the Problem Based Learning (PBL) model of the mathematics teacher on the surface area of the cylinder. The subject of this study was just one person who was selected purposively from three mathematics teachers of grade IX at SMP. The research instruments were the researcher herself, observation sheet, interview guide, and documentation. The data in this study were then analyzed in three stages, namely data condensation, data presentation, as well as conclusion and verification. The results of the research show that the teacher as a research subject who applies the PBL model in class is not fully in accordance with the theory. In addition, she treats the two research classes differently because of the differences in students' mathematical abilities in the two classes (epistemic injustice). Also, the application of the PBL model does not work as it should be in learning. This is because, on the one hand, there is still a lack of students' ability to understand the context of the problem given by the teacher. On the other hand, the teacher is still accustomed to conventional learning. Therefore, the teacher still tends to dominate learning activities. In fact, learning activities should be dominated by students.

Abstract

This study aims to describe errors in solving two-variable linear equation system story problems based on the Newman procedure in terms of the learning styles of class VIII junior high school students. The type of research used is descriptive qualitative research. By using purposive sampling technique, 3 research subjects were selected, namely one student in each type of learning style, namely visual, auditory, and kinesthetic. The instruments used in data collection were a learning style questionnaire, test questions about a two-variable linear equation system and interview guidelines. Data analysis techniques include data condensation, data presentation, drawing conclusions. The results showed that subjects with visual learning style made mistakes encoding error, subjects with auditory learning style performed processing skills error and encoding error, and subjects with kinesthetic learning styles made mistakes in comprehension error, transformation error, process skills error and enconding error.

Abstract

This research is a qualitative research with a descriptive approach that aimed to describe students' mathematical problem solving ability in terms the level of mathematical logical intelligence on sequence and series topic. The subjects in this research were 32 students of class XI MIA. The data collection techniques used in this research were the method of test and interview. The results of the research showed that of the three levels of mathematical logical intelligence, research subjects have similarities, starting at the step of understanding the problem subjects expressed the purpose of the problem with their own language and sentence. Then in devising a problem solving plan subjects make a mathematical model. At the step of carrying out the plan, the subjects determine the variable values needed to find a solution to the problem, and at the end of the problem solving process, subjects looking back the steps used and the results obtained. Meanwhile, from the three levels of mathematical logical intelligence, research subjects have differences, that are at the step of understanding the problem where the information revealed by the subject of KLMT is more complete than the subject of KLMS and KLMR. Meanwhile, at the step of carrying out the plan the subject of KLMT in using problem solving procedure more clear and precise. While, the subject of KLMS was able to complete the completion plan whose answer was finally correct, although the procedure used was incorrect. Then, the subject of KLMR faced an obstacle in solving problems because the procedure used was unclear.

Abstract

This study is a descriptive study with qualitative approach which aimed to describe the mathematical problem solving abilities by Polya step terms of abstract sequential thinking style, concrete sequential, abstract random and concrete random. The subjects in this study are 4 (four) of students grade VIII SMPN 24 Makassar selected purposively based on the different of thinking style. Data collection tool is questionnaire to classify students based on the thinking style and to determine the subject, written tests and interviews to determine the ability of students' mathematical problem solving. Data were analyzed to describe the mathematical problem solving ability of students based on Polya steps namely; (1) understanding the problem, (2) devising a plan, (3) carrying out the plan and (4) looking back. The results showed that students' of premises concrete sequential and abstract random thinking styles has the same ability on the fourth problem solving step in understanding the problem, devising a plan, carrying out the plan and looking back on the process and results. While students with the type of abstract sequential thinking style and concrete random has a different problem solving steps on each of the four stages.

Abstract

This study aims to describe students' reasoning in mathematical problem solving on the topic sequences and series viewed by prior knowledge. This type of research is descriptive qualitative. By using purposive sampling technique, then, the research subjects were selected as many as 2 students of class XI MIPA, one of the high schools in Makassar. The data collection technique uses test methods and interviews then through three stages of data analysis, namely data reduction, data display, and drawing conclusion. The results showed that the reasoning process of high-ability students was to associate the concepts and knowledge they had, gather evidence by mentioning things that were known and asked, linking the formulas that were already owned with the problems faced, identifying concepts used to solve problems, revealing reasons in explaining the steps in carrying out problem solving. And drawing conclusions explains the concepts used from the problem. While the reasoning process of low-ability students is to mention things that are known and asked and students cannot make any conclusions after solving the problem. This is because students have not fully understood the problem, students are not used to correcting the answers obtained, and students are not used to writing final conclusions.
