Abstract

This study aims to develop and produce valid and practical teaching materials on circles using GeoGebra for students and teachers in grade XI at MAN 2 Tanah Datar. The research method used was Research and Development (R&D) by adapting the 4D development model, which was limited to three main stages, namely Define, Design, and Develop. Data collection instruments included a validation sheet for experts and a practicality questionnaire. The data analysis technique used was a percentage formula for validity analysis and practicality analysis. The results showed that the teaching materials developed had a validity level of 87.12% with a very valid criterion. The level of practicality through trials at MAN 2 Tanah Datar showed an average student response score of 85.13% (very practical) and a teacher response of 79.63% (practical). Based on these results, it can be concluded that this GeoGebra-assisted Circle teaching material is feasible and very practical to use as a support for the mathematics learning process at the school. The implication of this research is the availability of interactive learning media that can help students visualize circle concepts with the aid of technology.

Abstract

This research is driven by suboptimal teacher digital literacy, inadequate school facilities, and the need to enhance principals’ managerial competence due to limited training and misconceptions regarding deep learning. The study aims to analyze the influence of principals’ managerial competence and teachers’ digital literacy on the readiness to implement deep learning, including the role of digital literacy as a moderating variable at public elementary schools in Kupitan District, Sijunjung Regency. The study employed a quantitative causal-associative approach involving 101 respondents selected via simple random sampling. Data were collected using Likert scale questionnaires and analyzed through simple linear regression and Moderated Regression Analysis (MRA). The research findings indicate that: Principals’ managerial competence significantly influences implementation readiness (t count 5.372 > t table 1.984); Teachers’ digital literacy significantly influences implementation readiness (t count 3.850 > t table 1.984), and; Digital literacy significantly moderates the effect of managerial competence on implementation readiness (sig. value 0.002 < 0.05). These findings underscore that the synergy between leadership and teachers’ digital proficiency is key to educational transformation in elementary schools.
