This research was conducted because of the importance of mathematical problem-solving abilities and the importance of learning tools as planning learning activities. Currently, teacher-made learning tools have not been able to activate students according to the demands of the 2013 curriculum. This development research aims to produce Problem Based Learning (PBL)- based products in the form…
This research is motivated by the low mathematical problem solving skills of students, especially on the topic of sequences and series. this is due to the non-optimal learning process carried out in schools resulting in learning loss and the formulation of an independent curriculum as an effort to help restore the learning process. Another cause of students' low mathematical problem-solving ski…
This research is motivated by the low ability of students' mathematical understanding and the limitations of Electronic Student Worksheets (E-LKPD). The purpose of this study was to develop an E-LKPD assisted by Video Learning Mathematics that meets valid and practical requirements to facilitate mathematical understanding of the material Surface Area and Volume of 3-D Shapes Flat Side. The…
This research is motivated by the not yet optimal mathematical problem solving ability of students due to the lack of availability of teaching materials that train students' mathematical problem solving abilities. One of the efforts that can be made to facilitate the quality of learning and the development of mathematical problem solving abilities is through the development of teaching mate…
ABSTRACT This final project discusses properties and characteristics of BF-algebras. These properties and characteristics are used to show properties, characteristics and relationhip between BF1, BF2, and BF3-algebras. Then, this final project discusses ideal concept in BF-algebras. Ideal concept in BF-algebras has some properties. These properties are used to show relationship between ide…
Penelitian ini dilatarbelakangi oleh masih terbatasnya perangkat pembelajaran yang sesuai dengan Kurikulum 2013, khususnya penerapan model dan pendekatan pembelajaran. Setelah dilakukan analisis terhadap perangkat pembelajaran diketahui bahwa perangkat tersebut sudah mengikuti standar yang telah ditetapkan pada kurikulum 2013. Tetapi RPP yang digunakan guru belum mencantumkan tujuan pembelajara…
This research is background by the low capability of students mathematic communication. One of the causes of them is the students are still shy and afraid to express their own opinion, they are not accustomed to having contextual questions, rarely to illustrate story questions into pictures questions or vice versa, careless in counting and seldom summarize what they have already found in their …
This research is motivated by the low ability of students' mathematical literacy. The reason is that students have not been able to model complex problems mathematically. In addition, students are not familiar with questions in everyday life that are complex and require logical and solutive reasoning. On the other hand, students' National Examination achievements in statistics material are also…
The purpose of this study is to produce Electronic-based Student Worksheets (LKS-E) using a Guided Discovery approach on Polyhedron Material Based that are valid, practical, and have a potential effect on the Mathematical Problem Solving Ability (KPMM) of junior high school students/MTs. The research method used in this research is Research and Development using a 4-D development model consisti…
The aim of the research was to produce e-learning materials assisted by GeoGebra to facilitate Mathematical Comprehension Ability (KPM) that meet the valid and practical requirements for Class VIII Relations and Functions material. This research is a 4D model development research (Define, Design, Development, Disseminate). The data collection instrument in the study consisted of validation shee…
Students' mathematical problem-solving skills are relatively low. Consequently, planning learning activities that can facilitate students' mathematical skills are needed. Teachers can use a cooperative learning model with a group investigation type to facilitate students' mathematical problemsolving skills. The implementation of the learning model must be supported by good learning instrum…
This research is motivated by technological developments that require teachers to prepare lessons well in order to facilitate students' mathematical problem solving abilities. One effort to facilitate students' mathematical problem-solving skills is to prepare learning resources that support technological developments. The results of the observations and analysis that the researchers carried ou…
The background of this research is due to the low ability of students' mathematical critical thinking, related to this, there must be an effort to improve the learning process as one of the main factors that affect learning outcomes. Learning in schools should be able to familiarize and train students to explore abilities and skills in critical thinking and also provide opportunities for studen…
Students’ mathematical problem-solving skills in Indonesia are still low and this motivates the researcher to conduct this study. The students’ mathematical problem-solving skills can be improved by utilizing learning models that can facilitate students to construct their knowledge. The results of the observations on some senior high schools in Pekanbaru showed that teachers still used…
This study aims to improve the learning process so that it can improve the mathematics learning outcomes of students in class XI IPS SMA Persada Pebenaan for the 2020/2021 academic year through the application of the Discovery Learning learning model. The process of collecting data involves observing the activities of teachers and students in action. This research is a classroom action research…
This research is motivated by the low ability of students' mathematical critical thinking and the limited teaching materials that are appropriate to the context and experiences of students. In this regard, this study aims to produce a material module on straight line equations based on the Realistic Mathematics Education (RME) approach assisted by QR Code to improve students' mathematical criti…
The research on the development of this teaching module was motivated by the existence of a new paradigm curriculum as the government's effort to deal with learning loss caused by distance learning during the co-19 pandemic. The instructional modules in the new paradigm curriculum are media tools/means, methods, instructions and guidelines that are designed systematically and attractively. …
This study aims to produce learning tools (syllabus, lesson plans, and worksheets) based on problem-based learning on valid and practical Pythagorean Theorem material. The 4D development model (Define, Design, Develop, Disseminate) in this study was carried out until a limited trial at the develop stage was then carried out at the disseminate stage. The instruments used include: (1) syllab…
Mathematical comprehension skills are an important part of learning mathematics. This study aims to produce a product in the form of a valid and practical E-LKPD (Electronic Student Worksheet) to facilitate students' mathematical comprehension skills on matrix determinants and inverse materials.
