One learning model that can help students in building mathe…
Mathematical Reasoning Ability (MRA) is an important ability for studentsin mathematical learning. However, students' MRA is still in the low category due to the lack of test instruments that teachers can use as a reference for training students' MRA. This study aims to develop a MRA test instrument on sequences and series material that are valid, reliable, and has a good level of difficulty an…
Improving the learning process and increasing students' mathematical problem solving abilities (KPMM) by applying the problem based learning (PBL) model are the main objectives of this research. The research applied is PTK with two cycles which are carried out in the even semester of the 2022/2023 school year. Class VII-E students of SMP Negeri 23 Pekanbaru were the subject of this study with a…
Mathematical literacy skills are very essential for students. Not only understanding math, but students must also be able to interpret math in real life. However, in reality, students' mathematical literacy skills are still relatively low. Many learners have not been able to find solutions to contextual problems and there are limited Learner Worksheets (LKPD) used by learners in facilitatin…
This development research aims to produce learning tools including syllabus, learning implementation plans (RPP) and student worksheets (LKPD) that are valid and practical based on the Problem Based Learning (PBL) model to facilitate the mathematical problem solving abilities (KPMM) of class VII students SMP/MTs on comparative material. This development research uses a 4-D model (Define, De…
The cause of the low KPMM students is that students only memorize the formulas that the teacher gives without understanding the systematics concepts in the implementation of learning. Another thing, because students have not been able to do questions that are different from the example questions the teacher gives. KPMM can be developed throght the implementation of learning, namely by giving st…
This research is motivated by the difficulties experienced by teachers in developing learning tools that are in accordance with the 2013 curriculum. A learning tool is needed so that it can increase student understanding and familiarize students with solving problems in everyday life. This study aims to produce a syllabus, lesson plans, and LAS with a problembased learning (PBM) model on th…
The purpose of this research is to develop mathematics learning device that are Lesson Plan (LP) and Students Worksheet (SW) on subject quadrilateral through the implementation of Discovery Learning for grade VII SMP/MTs with minimum valid criteria. This research method used ADDIE model that consist of analysis, design, development, implementation and evaluation, but the reserch only done …
The background of this study is the restrict of mathematics learning device as supporting learning referring to 2013 Curriculum. This researches aims to develop mathematics learning device form of syllabus, RPP and LKPD with problem based learning model on the subject matter of the social arithmetic the 7th grade students of SMP/MTs. Research development by Thiagarajan. Development is done thro…
This research was motivated by the loss of learning (loss of learning) during the Covid 19 pandemic. The loss of learning was due to the lack of optimal learning processes carried out in class so that students' skills decreased, including reasoning skills and mathematical proof. The need for teacher creativity to plan learning so that the quality of education increases, especially in the transf…
This research is motivated by the low critical thinking skills of students and the minimal availability of merdeka curriculum-based mathematics assessment instruments. This study aims to produce a merdeka curriculum-based assessment instrument to measure the critical thinking skills of phase E students on sequences and series material that is valid, reliable, has a level of difficulty and good …
According to the Regulation of the Minister of National Education of the Republic of Indonesia Number 21 of 2016, one of the objectives of learning mathematics in secondary schools is to equip students with mathematical problem solving abilities (KPMM). However, in reality the participants' KPMM is still low, which is supported by several previous studies which show that the results of the stud…
The low ability of students mathematical understanding in the material for Rows and Series is due to the lack of availability of teaching materials that suit the needs of students. This study aims to produce E-LKPD assisted by Liveworksheets with a Problem Based Learning model in class X SMK/MAK Sequences and Series material that are valid and practical. This research is development resear…
Syllabus, RPP and LKPD which were prepared using the Problem Based Learning model which has been considered valid and practical in the material of the Two Variable Linear Equation System are learning device products produced in this study. This research is included in development research, using the 4-D model, namely define; design; develop; and disseminate. The research was conducted by involv…
This study aims to produce mathematics learning media based on a scientific approach assisted by Articulate Storyline material on lines and angles to facilitate KPMM for SMP/MTs students who meet valid and practical requirements. The development model used is the 4D model which includes definition, design, development and deployment. The subjects in this study were class VIII students of SMP in…
