For pre-service teachers to develop learners' number sense, they need have a broad repertoire of non-standard calculation strategies. In this paper, we present an analysis of selected research literature from 2000 to 2022 on pre-service teachers' mental mathematics published in peer-reviewed journals. The results of this brief review indicate that…

Experimental research in education and training programs typically involves administering treatment to whole groups of individuals. As such, researchers rely on the estimation of design parameter values to conduct power analyses to efficiently plan their studies to detect desired effects. In this study, we present design parameter estimates from a…

This literature review synthesized current research on preservice and in-service programs that improve K-6 teachers' attitudes, self-efficacy, or knowledge to teach computing, coding, or computational thinking. A review of current computing training for elementary teachers revealed 21 studies: 12 involving preservice teachers and nine involving…

Teaching with technology is considered a necessity in the U.S. mathematics classroom. However, few studies have established explicit considerations to support technology-enhanced student achievement. The purpose of this study was to characterize the effectiveness of technology in the mathematics classroom by systematically reviewing meta-analytic…
