Abstract

Abstract Mathematics is a science with a broad concept. The breadth of concepts in mathematics, does not rule out the possibility that these concepts are interrelated. For example, in studying linear equations with one variable, students must first know the concept of algebraic operations. This study aims to describe the concept of mathematical connection ability, describe the learning strategies used to improve the mathematical connection skills of junior high school students, and provide an overview of learning designs to improve mathematical connection skills for junior high school students. The method used by the author is a literature review method. Based on the studies conducted, it can be concluded that the ability of mathematical connection is the ability of students to relate between topics in mathematics and then mathematics topics with other sciences or with everyday life. The strategy or model used in learning mathematics is an important part for an educator in planning learning designs that will be applied in the learning process. Therefore, it is important for further researchers to apply existing strategies or models to different materials, so that they can be studied further about students' connection abilities in the learning process.

Abstract

Technological developments in the field of education require teachers to be more creative in creating technology-based learning media by utilizing Android. Therefore, this study aims to develop an Android on the material of a two-variable linear equation system for class VIII students of SMP Negeri 2 Kupang that is valid, practical and effective. The method used in this research is the R&D method and the model used is the ADDIE development model. The data collection techniques and instruments used are interviews, questionnaires and tests. The data analysis techniques used are field study analysis techniques, validity analysis techniques, practicality analysis techniques and effectiveness analysis techniques. The results showed that the developed media met the criteria of being valid, practical and effective. The average total validity by material experts is 4.58, practitioners are 4.65 and media experts are 4.25, “very valid”. The average total practicality of the teacher is 4.75 and the students where in the small class trial is 4.63, in the large class trial it is 4.43 "very practical". The percentage of completeness in small group trials obtained results of 100% "very effective", in large group trials obtained results of 81.25%, so android-based learning media is very feasible to use

Abstract

Technology in education demands innovative and creative learning by utilizing android smartphones to improve student learning outcomes. Therefore, this study aims to develop and produce an android-based application on algebraic form material to improve student learning outcomes for grade VII students of SMP Negeri 8 Kupang that is valid, practical, and effective and to find out teacher and student responses to the application.The method used in this study is the Research and Development (R&D) research method and the model used for ADDIE development which consists of 5 stages, namely analysis, design, development, implementation andevaluation (evaluation). Data collection techniques used are interviews, questionnaires and learning outcomes tests. The data analysis technique used is qualitative data analysis and quantitative data analysis.The results showed that the Algebra Learning Application met the valid, practical and effective eligibility criteria and was able to improve student learning outcomes. The average total validity by material experts is 4.01, education practitioners are 4.23, and media experts are 4.66, with the "valid" category. The average total practicality of the teacher is 4.81 and that of the students in the small group is 4.2, while in the large group is 4.62 with the "practical" category. The percentage of mastery learning using learning media is 83.33% in the "effective" category. There was an increase in interest and completeness of student learning outcomes which initially increased from 40% to 83.33% so that the Algebra Learning application was very feasible to use.

Abstract

This review aims to describe the model, characteristics, and design of blended learning, to describe the trend of research blended learning in supporting the development of students' mathematical thinking skills and to provide recommendations for blended learning in supporting the development of students' mathematical thinking skills in the future. The method used in this paper is an article review method which is carried out in three stages, namely identifying keywords related to blended learning in developing mathematical thinking skills, article search strategies, and analyzing articles. Blended learning is a combination of learning patterns, between face-to-face learning and online learning. The trend of Blended learning is carried out with online learning and face-to-face learning in class is carried out alternately (rotational model), using various LMS. The results of the article analysis show that the blended learning stage can develop students' mathematical thinking skills, namely the seeking of information stage students are directed to think critically. At this stage students are more motivated and independent in finding or accessing materials online. Then at the stage of acquisition of information and synthesizing of knowledge, students are directed to solve problems, use mathematical understanding skills, reasoning, connection and representation skills, communication and collaboration, and think critically through discussions, presentations, and work on practice questions. In addition, students look more enthusiastic and motivated because it is adjusted to their learning style and learning speed and students are directed to be independent in learning the material. The researcher recommends a blended learning design using the flipped classroom model with online learning using the Moodle LMS in which each stage of blended learning, students are directed to rely on mathematical thinking skills. Keywords : Blended learning and mathematical thinking skills
