Abstract

This study aims to produce an instrument for assessing mathematical critical thinking skills on material derived from algebraic functions that have been tested for validity. The form of research carried out is research and development and the development model used is a 4-D model (Define, Design, Develop, Disseminate). The research location is at SMAN 1 Tembilahan Hulu in the even semester of the 2021/2022 academic year. The object of research is an instrument for assessing mathematical critical thinking skills in class XI class derivatives of algebraic functions. The data collection instrument used an instrument validation sheet. Data analysis shows that the results of the validation of the mathematical critical thinking ability assessment instrument obtained an average value of the Aiken index of 0.811 with a very valid category and content validity with an average of 0.723 with a valid category. In terms of discriminating power, there are 2 questions with poor discriminating power and 6 questions that can be used to measure the level of students' mathematical critical thinking skills. So, it can be concluded that the development of an instrument for assessing mathematical critical thinking skills is to produce an instrument that has been tested for validity.

Abstract

The purpose of this research to describe the level validity of mathematics lesson plan by using the Contextual Teaching and Learning (CTL) Approach on Quadrangle Substance at Grade VII MTs Negeri 3 Siak which was valid test. The development model in this research used an R&D model with six stages were the researcher have modified depends on the needs and conditions with current situation now it’s covid-19 pandemic. These six stages arepotential and problems, data collection, product design, design validation, design revision and final product. The data collection technique used in this research was the validation of lesson plan, the kind of data collection instrument was the form of a validation sheet. While the data analysis technique used in the form of descriptive analysis by describing the validity of the lesson plan which was developed by the researcher. The results of this research, the RPP validation were 85.86% with very valid criteria. While the results of LKPD validation were 89.81% with very valid criteria. Based on the results of this research, it can be concluded that the development of mathematics lesson plan with a Contextual Teaching and Learning (CTL) approach on quadrangle substance at grade VII MTs Negeri 3 Siak has been suitable for the validity.

Abstract

This study aims to determine the validity of the mathematics learning tools in the form of Student Worksheets (LKPD) using the Problem Based Learning (PBL) learning model on statistical material. This study uses a type of R&D research that was developed using the modified Plomp development model because the research was carried out during the Covid-19 pandemic, so only 4 stages were carried out, namely 1) the initial investigation stage, 2) the design stage, 3) the realization/construction stage, 4) stage of test, evaluation and revision. The data collection instrument used was the LKPD validation sheet. The data collection technique used is a non-test technique with validation sheets from 2 lecturers of mathematics education at FKIP UIR and 1 mathematics teacher at MTs Hidayatul Muta'allim Mengkirau. The analytical technique used is validation data analysis. From the results of the study, the results of the LKPD validation were 85.47% with very valid validation criteria. Based on this research, it was obtained a mathematics learning tool in the form of LKPD with a Problem Based Learning (PBL) model on statistical material for class VIII MTs Hidayatul Muta'allim Mengkirau which had been tested for validity.

Abstract

Tujuan dari penelitian pengembangan ini adalah untuk menghasilkan sebuah produk berupa perangkat pembelajaran matematika pada materi sistem persamaan linear dengan menggunakan model problem based learning. Jenis penelitian yang digunakan yaitu model pengembangan 4D yang telah dimodifikasi. 4 tahapan 4D yaitu tahap define, tahap desain, tahap development dan tahap disseminate. Teknik pengumpulan data menggunakan angket dan instrument pengumpulan data yaitu lembar validasi yang dirancang menggunakan skala likert 4 tingkat. Validasi dilakukan kepada empat orang validator yaitu dua orang dosen matematika Fakultas Keguruan dan Ilmu Pendidikan Universitas Islam Riau dan dua orang guru matematika. Adapun teknik analisis data yang digunakan yaitu teknik analisis kuantitatif dari data hasil validasi. Hasil yang diperoleh pada penelitian ini berupa hasil validasi perangkat pembelajaran dengan rata-rata keseluruhan pada RPP sebesar 87,36% dengan kriteria sangat valid sedangkan rata-rata keseluruhan pada LKPD sebesar 84,56% dengan kriteria sangat valid.

Abstract

This study aims to find out the improvement of students’ mathematical critical thinking viewed from curiosity through teaching materials with Problem Based Learning model. This is quasi-experimental research. The samples are, where the overall population consists of 75 samples divided into two classes.  This research employed a simple random sampling technique.  The instruments were the mathematical critical thinking skill test and curiosity questionnaire. The technique of data collection was carried out with test and non-test techniques. The data were analyzed through a two-way Anova test. Based on the analysis and interpretation of the research findings, it was found that: there was an improvement in students’ mathematical critical thinking skill from High curiosity by using teaching materials with Problem Based Learning model; 1) There was an improvement from  Average curiosity through learning with Integral Calculus teaching materials; 2) There was an improvement from Low curiosity; 3) There was no improvement from the level of curiosity (High,  Medium,  Low) through Problem-based Learning. 4) There was no influence between the level of curiosity and learning in improving students’ mathematical critical thinking skills. Do more in-depth studies related to improving mathematical critical thinking skills by reviewing other affective aspects.
