Pengaruh Model Pembelajaran Discovery Learning Terhadap Kemampuan Penalaran Matematis Peserta Didikkelas Viii SMPN 3 Ranah Pesisir

Abstract

Mathematical reasoning ability is very important for students to be able to make decisions or solution in solving various problems in the mathematical context. The purpose of the study was to describe the effect of the Discovery Learning model on students mathematical reasoning abilities better than students mathematical reasoning of students who learn by using direct learning and describe the development of mathematical reasoning abilities of student who study with the Discovery Learning model. The type of research is quasy-experiment and descriptive with a Randomized Control Group Only Design. The research instrument is a test of mathematical reasoning abilities. From the data analysis it was concluded that students' mathematical reasoning abilities that applied the Discovery Learning model were better than the students' mathematical reasoning abilities who applied direct learning in class VIII SMPN 3 Ranah Pesisir. there was an increase in students' mathematical reasoning abilities while learning to apply the Discovery Learning model. The development of mathematical reasing skills by applying Discovery Learning model has increased in each indicator.

The CORE Learning Model of Junior High School Students for Improving the Mathematical Reasoning Ability

“…In this case, the stages of the CORE model offer four processes, namely connecting (connecting old information with new information), organizing (organizing the knowledge gained), reflecting (rethinking the information obtained), and extending (expanding and developing the knowledge gained). 5 (Nuri & Dwina, 2019) The Influence of the CORE Learning Model on Students' Mathematical Reasoning Ability in Class VIII SMPN 11 Padang…”

Pengaruh Model Pembelajaran Discovery Learning Berbantu Konten Kreatif TikTok Terhadap Kemampuan Penalaran Matematis Siswa

“…Kemudian setelah mendapatkan hasil awal, siswa diberikan perlakuan dengan menerapkan model pembelajara discovery learning berbantuan media TikTok, pembelajaran yang berlangsung menggunakan langkahlangkah pada model tersebut. Media Pembelajaran juga berbasis model pembelajaran discovery learning yang disertai berbagai latihan soal seperti yang disampaikan oleh Megia (2022).…”

Analysis of Students' Mathematical Reasoning Ability in Learning Realistic Mathematics Education in terms of self-regulation of quadrilateral material

“…Indonesia ranks 73rd out of 79 countries in the 2018 PISA (OECD, 2018). Based on what was disclosed by Widyaningsih et al (2021) the achievement of scores that are classified as still below is because Indonesian students are still unfamiliar with working on TIMSS and PISA questions which in general are able to measure reasoning abilities and argue in a mathematical calculation. Based on the opinion of Shonia et al (2021), One way to improve the quality of education in Indonesia is to have the ability to think the good one.…”
