Mathematical Learning Development using Discovery Learning Model to Improve Mathematical Understanding Skills of Students

Abstract

This study aims to produce a mathematics learning tool with a discovery learning model on rectangular and triangular material, with valid, practical and effective criteria to improve the mathematical understanding ability of grade VII students in junior high school. The type of research was development research with the design development using Borg and Gall. This study produced learning tools consisting of syllabus, lesson plans and student worksheets (LKPD). The results of the study showed that the learning tools met valid, practical and effective criteria. The validity of the product development was determined by expert validation with an average value of 4.46 with a very valid category. The practicality of the product development is determined by the teacher with an average of 99%, students 90.57% and observers 4.16 which is categorized as very practical while the effectiveness of the development product in terms of the achievement of learning objectives using KKM scores of 75 is obtained from the test results of mathematical understanding ability with the results there is an increase in learning outcomes using developed learning tools.

Improving Students Mathematical Understanding by Using Discovery Learning Models for Senior High School Students in Kampar District

“…The teacher is always motivating, giving explanations about what they have to do and convincing students until the second meeting and so students begin to be trained to work on problems so that their mathematical understanding increases. This strengthens and complements research from Susanti et al (2017), Moreno (2018) and Kartika et al (2020) who conclude that discovery learning can improve students' mathematical understanding.…”

Development of Guided Invention Based Learning Tools on Circle Material to Facilitate Mathematical Comprehension Ability of Class VI SD / MI

“…Learning devices that are made are only limited to the administrative requirements provided by the teacher without paying attention to the goals to be achieved (Atika, 2020). This is in line with Kartika (2020) which states that the learning tools used by teachers such as the lesson plans that are compiled do not yet refer to the RPP components stated by Permendikbud No. 22 of 2016, for example the GPA that has not used operational verbs, the details of learning activities are not in accordance with the learning model used, the scientific approach has not been seen and the steps of the learning model used have not been seen in learning activities.…”

The Effectiveness of Discovery Learning Model in Writing Descriptive Text

“…Indications of this last trend can be seen from the learning process that develops during the process of learning English, where the class tends to be passive. The learning profile of students is more in the learning behavior of listening to information activities (Kartika et al, 2020) with dominant teacher activities and taking many positions in front of the class who tend to "patronize", rather than teaching students to learn to think about subject matter (Al Muchtar, 2012).…”
