Development of a mathematics instructional media by utilizing geogebra to enhance junior high school students’ Higher order thinking skills

Abstract

This study aimed to develop an interactive visual media called Geoactive (Geogebra interactive) by employing Geogebra to improve students higher order thinking skill (hots) in the learning of solid geometry. The media was developed by using the model of 4D from Thiagarajan, which consists of define, design, develop, & disseminate. The product testing was conducted in SMPN 2 BUA, and two validators validated the product. Results show that: (1) the Geoactive developed was declared valid with the average assessment score of 4.45 which was in the category of very good; (2) the interactive media developed was declared practical with its indicator of the average of learning implementation being 78.67% which was in the category of good and the score of students’ response was 2.89 which was categorized as good; (3) the Geoactive developed was effective with the completeness indicator of conceptual understanding and problem solving was 77,14% and 71,43%, respectively. Both of the two scores were categorized as high

Improving students’ ability in learning mathematics by using the science, technology, engineering, and mathematics (STEM) approach

“…A questionnaire was developed to measure student learning motivation. This data collection was developed based on a previously described conceptual framework that describes the framework of (1) identifying learning and (2) predicting student behavior (Ilyas et al, 2020;Ma'rufi et al, 2020). Both can be modulated by various interventions and multiple STEM retention initiatives.…”

Pengaruh Media Dakon Matematika Terhadap Hasil Belajar Matematika Siswa Materi Penjumlahan

“…Karena dalam kegiatan tersebut, ketidakjelasan materi yang disampaikan dapat dibantu dengan menghadirkan media. Kerumitan materi yang akan disampaikan kepada siswa dapat disederhanakan dengan bantuan media, bahkan keabstrakkan materi dapat dikonkretkan dengan adanya media (Ilyas et al, 2020;Andriani et al, 2021). Berdasarkan karakteristik siswa MI/SD yang masih membutuhkan bendabenda konkret dalam proses pembelajaran khususnya pada pelajaran matematika, maka diperlukan media pembelajaran yang menarik untuk mempermudah siswa dalam memahami materi pembelajaran matematika, khususnya pada pokok pembahasan penjumlahan.…”

The Implementation of Online Mathematics Games to Improve Mathematical Representation Ability of Junior High School Students in Lhokseumawe

“…Among the innovations that teachers can make by applying learning media in the learning process. Accorded (Ilyas et al, 2020) said learning media has several roles, namely that it can concret things that are abstract and help students explain subject matter that is difficult to understand verbally. As explained (Andini & Yunianta, 2018) by using the media, will students to attract more attention and not easily get bored in learning.…”
