Abstract

This researchaims to describe students' mathematical creative thinking abilities in terms of learning styles and gender.The method used is descriptive qualitative, data collection techniques in this study were carried out through direct activities at school. Data collection was carried out by means of tests of mathematical creative thinking skills, learning style questionnaires, interviews and documentation.The results of the research are (1) students 'mathematical creative thinking abilities in terms of visual and gender learning styles are more likely to fulfill authenticity and detail indicators, but what is unique is that only one subject can fulfill fluency and flexibility indicators, (2) students' mathematical creative thinking abilities in terms of style. Auditory learning and gender are more likely to meet the indicators of authenticity and detail, however, what is unique is that only one subject cannot meet the indicators of flexibility and fluency, and (3) students' mathematical creative thinking abilities in terms of kinesthetic learning styles and gender, there are only two students who tend to fulfill indicators of fluency, flexibility and detail and two students meet indicators of fluency and detail because they are able to solve problems in a very detailed and systematic manner,while the other two students only meet the authenticity indicator

Abstract

This research aims to describe learners' mathematical reasoning skills based on their personality types on the 9E learning cycle with kid-friendly rubrics. This research is mixed-method with a sequential explanatory design. The data collection of mathematical reasoning skills was done by using a test on four indicators. On the other hand, the data of personality types were taken by using KTS II inventory, documentation, and interview. The research subjects consisted of seventh graders of Private JHS Gema Buwana in 2020/2021. The findings showed that the learners' mathematics reasoning skills with guardian type could explain the model, fact, property, correlation, and pattern. These learners could use the correlation pattern to analyze the situation, create an analogy, and generalize. The artisan type could explain the model, fact, property, correlation, and pattern. They could create assumptions and evidence. The rational type could create a logical conclusion by explaining the model, fact, property, correlation, and pattern. They could also create assumptions and evidence, use the correlation pattern to analyze the situation, create an analogy, or generalize. On the other hand, the idealist type could explain the model, fact, property, correlation, and pattern. They could also make assumptions and evidence.

Abstract

The aim of this research is to produce a learning module with mobile augmented reality based on 9E Learning Cycle. This research is a type of research design. The development model used is ADDIE model which consists of five development phases namely analyze, design, development, implementation, and evaluation. The results of this study are learning modules that have been installed with QR-code and ModulAR apps that runs on the Android operating system. The results of validation get from experts’ reviewer that consist of 4 mathematics education lecturers and 3 mathematics teachers that showed the predicate of products was valid without revision for use. Then, the module and ModulAR apps has been implemented at SMPN 2 Mantup, Lamongan which involved 68 students who were divided into experimental and control classes. The module and ModulAR apps has received a practical predicate based on the analysis of the practicality questionnaire filled out by experimental class’s students. The use of learning modules with mobile augmented reality based on 9E Learning Cycle is also effective to improve problem solving skills. It can be seen from the average n-gain score obtained 61.10% which is include in the moderate category and the results of the independent-samples t test show that the average of problem solving skills improvement in the experimental class is significantly higher than the control class. The purpose of this research was to produce a learning module with mobile augmented reality based on 9E Learning Cycle. This type of research was a research design developed using the ADDIE development model with five development steps, namely analysis, design, development, implementation, and evaluation. The results of this study are the learning module and the ModulAR application that runs on the Android operating system. The results of expert validation consisting of 4 mathematics education lecturers and 3 SMP / MTs mathematics teachers showed a valid predicate without revision for 8 aspects of validity. The product developed has been implemented at SMPN 2 Mantup, Lamongan which involved 68 students who were divided into experimental and control classes. The product developed has received a practical predicate based on the analysis of the practicality questionnaire filled out by students in the experimental class. The use of learning modules with mobile augmented reality based on the 9E Learning Cycle is also effective in improving problem solving skills. This is based on the average n-gain score of 61.10% which is included in the intermediate category and the results of the comparative test show that the average increase in problem-solving abilities in the experimental class is higher than the control class.

Abstract

The application of learning models and the selection of learning assessments affect learning outcomes. Besides that, the use of interactive software can also make it easier for students to understand the concept of geometry. This study aims to explain the quality of mathematics learning and the ability of thinking geometry in terms of students' self-efficacy of learning of problem-based learning models assisted by GeoGebra with self-assessment. The study was conducted with a mixed-method approach. The study population was students of class XI Al-Asror Semarang Vocational School with sample class XI TPTU 1 as an experimental class and XI TPTU 2 as a control class. The results showed that the quality of learning of problem-based learning models assisted by GeoGebra with self-assessment of the ability to think geometry and self-efficacy in class XI Al-Asror Vocational High School Semarang was very good and the ability to think the geometry of students in the high self-efficacy group showed very good categories, self-efficacy was included in the good category, and low self-efficacy included in the good enough category. So of learning model of problem based learning assisted by GeoGebra with self-assessment can improve students' geometry skills and self-efficacy.
