On the basis of a substantial, robust, and well-replicated cognitive science research literature, interleaving has been recommended across a range of professional pedagogical works as an evidence-based strategy for mathematics teachers. This report first notes the conflation of interleaving and spacing effects underpinning those recommendations…

Purpose: This study aims to explore how a Chinese lesson study (LS) supports a teacher's learning of transforming curriculum reform ideas into classroom practices. Design/methodology/approach: Data analyzed in this study included lesson plans, three videotaped research lessons, three audio-taped group meetings, interviews, the teacher's reflection…

The effectiveness of an experimental middle school fraction intervention was evaluated. The intervention was centered on the number line and incorporated key principles from the science of learning. Sixth graders (N = 51) who struggled with fraction concepts were randomly assigned at the student level to the experimental intervention (n = 28) or…

In 2010, a comprehensive secondary school in the south of England implemented a whole-school approach to "learning to learn" (L2L). Drawing on a range of evidence-based practices, a team of teachers worked collaboratively to design and deliver a taught L2L curriculum to all students throughout Key Stage 3. In total, the first cohort of…

The purpose of this report is to describe a science competency model and 3 related learning progressions, which were developed by applying the "CBAL"™ approach (Bennett & Gitomer, 2009) to the domain of middle school science. The Cognitively Based Assessment "of", "for", and "as" Learning (CBAL) science…
