This study explored an emerging practice, online video coaching, which builds on the affordances of digital technology to allow coaches to work with geographically distant teachers. Content-focused mathematics coaching has proven successful in a face-to-face environment because of its personalized nature, long-term sustainability, and the…

This study discusses the development and effectiveness of game instruction on mathematical communication skills. This feature, developed using Microsoft PowerPoint, provides learning instructions with a chain game called algebra dominoes. The principles of independent learning and mastery learning are strategies in learning to ensure that students…

Recent work describes methods for systematic, data-driven improvement to instructional content and calls for diverse teams of learning engineers to implement and evaluate such improvements. Focusing on an approach called "design-loop adaptivity," we consider the problem of how developers might use data to target or prioritize particular…

Formative assessment helps teachers make effective instructional decisions to support students to learn mathematics. Yet, many teachers struggle to effectively use formative assessment to support student learning. Therefore, teacher educators must find ways to support teachers to use formative assessment to inform instruction. This case study…

The COVID-19 pandemic has been called an educational catastrophe. It caused massive disruptions in education, learning loss for students, and massive increases in teacher workloads, stress, and health-related issues. There were significant issues of student disengagement and rampant cheating on assessments. This paper looks not at the huge…

The mathematical ability of Indonesian students is still very low compared to other countries. One alternative to overcome the problem is by creating learning instructional that allows students to learn well. Most of learning instructional developed today do not accommodate the student learning styles especially in schools that have classified…

To help teachers improve their efficiency and effectiveness, this dissertation study uses regression analysis to assess two middle Georgia counties' CRCT and Math 1 EOCT data in order to determine the usability of the CRCT to enhance instruction in Math 1. Data were collected from the 2009 and 2010 CRCT administrations and the 2010 and 2011 EOCT…

While mathematics education researchers have long characterized student performance marked by mathematical explanations, arguments, and justifications as evidence of mathematical reasoning and understanding (e.g. Schoenfeld, 1992), current education policy has begun to move in a similar direction, emphasizing sense making and mathematical…

For the thirty-sixth year, the Research and Theory Division of the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented at the annual AECT Convention in Anaheim, California. The Proceedings of AECT's Convention are published in two…
