The Effect of STAD cooperative model by GeoGebra assisted on increasing students’ geometry reasoning ability based on levels of mathematics learning motivation

Abstract

This study aims to analyze the improvement of geometric reasoning abilities of students of SMA Negeri 1 Sampara, Kabupaten Konawe, Sulawesi Tenggara, Indonesia. Here, we compare three models of learning; (1) STAD cooperative model by GeoGebra assisted; (2) a model of the STAD cooperative without assistance from GeoGebra; and (3) conventional learning models. This study was applied to three different classes, where each class consisted of the high, medium, and low motivation students. Data collection was done by giving a mathematics learning motivation questionnaire and giving a test of students’ geometric reasoning abilities. The data analysis technique uses inferential statistics to test normal assumptions and homogeneity and hypothesis testing using the One-Way ANOVA Test. Based on the results of the study showed that the effect of using the STAD type cooperative learning model with the help of GeoGebra was higher when compared to the other two models. That difference occurs at all levels of motivation. On the other hand, the STAD model without GeoGebra only affects high and moderate motivation students. Meanwhile, low motivation students did not show significant differences with the direct learning model.

Penerapan visual basic for application spreadsheet excel untuk simulasi konsep motor listrik tiga fasa dan aplikasinya sebagai media pembelajaran

“…Dengan simulasi, lingkungan pekerjaan yang kompleks dapat ditata menyerupai dunia nyata [2]. Dewasa ini, terdapat banyak jenis perangkat lunak (software) yang dapat digunakan sebagai media untuk mensimulasikan atau memvisualisasikan materi-materi fisika diantaranya, yaitu; PSIM Simulation [3], PHET Simulation [4], easy java/javascript Simulation (Ejs) [5], GeoGebra [6] dan Visual Basic For Application pada spreadsheet Excel [7]. Namun setiap media memiliki keunggulan dan kelemahan yang berbeda, perbedaan tersebut dapat berupa penyempurnaan media sebelumnya.…”

Using IoT technology for monitoring Alzheimer’s and elderly patients

“…One of the challenges is privacy and security. IoT devices collect sensitive data, such as health information, and there is a risk of data breaches and unauthorized access [27], [28]. Another challenge is the need for standardization and interoperability.…”
