Mathematical reasoning is a critical feature emphasized in the objective of mathematics education since it may be utilized to solve mathematical problems and other difficulties. This study aims to provide student worksheets based on Realistic Mathematics Education (RME) on circle material that are valid, practical, and useful in increasing students' mathematical reasoning abilities. This research used a 4-D development model. Validation sheets, practicality questionnaires, and test questions were employed as research tools.

. The development of website-based worksheets represents an innovation to enhance the quality of education during the Covid-19 pandemic. The aim of this study is to outline the process of creating and assessing the feasibility of website-based worksheets on the topic of flat 3D shapes. The ADDIE model, consisting of five phases: analysis, design, development, implementation, and evaluation, was used in this research. The instruments utilized included media and content validation questionnaires, teacher and student response questionnaires, and tests.

Calculus courses have become the basis of other mathematics courses. However, students often find obstacles in this course that cause low mastery of calculus.Therefore we need an in-depth analysis of students' obstacles in learning calculus to develop proper learning materials and methods. This research aims to analyze the students’ learning obstacles in solving mathematical problems in calculus courses. This research is a qualitative descriptive study.

. This study aims to determine the effect of the Problem-Based Learning model assisted by visual media on student learning outcomes on a Similarity topic. This research is experimental research using a randomized pretest-posttest control group design. The population used in this study were ninth-grade students of one of the junior high schools in Kerinci, Jambi. The sample selection used a random sampling technique. Research data was obtained through pretest and posttest.

The purpose of this research is to determine the improvement of students' creative thinking through a scientific approach that integrated a problem-based learning m odel on set problems. This research used quasi-experimental design which compared pretest and posttest results between two groups. The population of this study was all of the eighth-grade students at one of state Islamic junior high schools (MTsN) in Sungai Penuh, Jambi, Indonesia. The research sample consisted of students in two groups that were randomly selected.

Penelitianini bertujuan untuk menghasilkan Lembar Kerja Peserta Didik (LKPD) Berbasis Pendekatan Konstruktivisme pada materi barisa dan deret untuk meningkatkan hasil belajar peserta didik.Model pengembangan yang digunakan dalam penelitian ini adalah pengembangan model ADDIE. Rancangan LKPD divalidasi oleh pakar dan diujicoba. Instrumen validitas menggunakan lembar validasi dan instrumen praktikalitas menggunakan angket respon guru dan angket respon peserta didik.

Comparison, ratio, and proportion were any problems encountered in everyday life. To understand it, highlevel proportional reasoning is needed. The analysis for this ability was important, especially on any students with an auditory learning style that rely on hearing to understand the lesson. This study attempts to describe the proportional reasoning level of students with the auditory learning style in solving the proportion problems. Research informants were selected using purposive sampling technique.
