The study advances the instrumental approach to mathematics education (Drijvers et al., 2013; Trouche, 2003), aiming to elucidate the interplay between students' reasoning competency, conceptual knowledge and tool utilisation in dynamic digital geometry and algebra environments. The dynamic properties of these environments pose a nuanced…

Information and communication technologies (ICTs) in basic education, i.e. K12 education, have often been constrained by sociocultural context and limited to pedagogical aspects, and these innovations have not yet catalyzed curriculum reform as expected. To address this research gap, this study adopted a key-competence-based subject knowledge…

Background/Context: A minority of U.S. eighth graders reach the proficient level on the National Assessment of Educational Progress (U.S. Department of Education, 2021). Early evidence suggests that the pandemic has made things worse, especially so for underserved student populations (Lewis et al., 2021). Math proficiency is central to advanced…

Education for sustainable development (ESD) provides crucial opportunities for young people to be involved in complex sustainability issues. This study contributes to existing knowledge about primary school teachers' approaches to ESD across a range of subjects. Norwegian schools can join the Sustainable Backpack programme (SBP), which supports…

Education Policy Innovation Collaborative (EPIC) partnered with the Michigan Department of Education (MDE) to conduct a multi-year study of Michigan's implementation of competency-based education in K-12 schools. This mixed-methods study seeks to investigate the implementation and effectiveness of CBE using data from surveys administered to 21j…

In 2013 the Vermont legislature enacted Act 77 mandating that students in Grades 7-12 develop personalized learning plans (PLPs) to guide them toward high school graduation using proficiency-based requirements. In the present qualitative self-study, we document the impact of implementation of a personal learning framework integrating PLPs into a…

This research examined the effectiveness of a design-based, continuous professional development (CPD) programme intended to promote teachers' self-confidence and teaching reflection skills. The CPD was associated with teacher implementation of theoretically devised, motivational, context-based, inquiry teaching modules, based on a justified…

The purpose of this quantitative study was to examine the academic impacts of the Twenty-First Century Community Learning Centers on students who participated in this program. The following research questions guided the study: (a) are there significant differences between the Criterion Reference Competency Test English Language Arts scores of…

This report makes recommendations for the development of middle-school assessment in mathematics, based on a synthesis of scientific findings in cognitive psychology and mathematics education. The focus is on background research, rather than test specifications or example tasks. Readers interested in early development and pilot efforts associated…
