Video games' capacity to facilitate complex and interactive modes of engagement has led to their portrayal as particularly effective means for designing authentic and situated learning environments, which overcome the artificial and abstract nature of conventional teacher-centered schooling. Focusing on the intentional use of progressive-oriented…

This paper provides a summary account of Activity-Centred Analysis and Design (ACAD). ACAD offers a practical approach to analysing complex learning situations, in a way that can generate knowledge that is reusable in subsequent (re)design work. ACAD has been developed over the last two decades. It has been tested and refined through collaborative…

One of the topics within the course of Essential Concepts in School Mathematics (ECSM) for prospective mathematics teachers concerns maximum and minimum problems. This type of problems requires mathematization, i.e., the activity of transforming a problem into a symbolic mathematics problem and of reorganizing within the mathematical system, in…

This study investigated whether an instructor's gestures can signal the underlying conceptual structure of a lesson and foster learning. In Experiment 1, 123 undergraduates watched a video comparing eastern and western steamboats in which the instructor produced structure gestures, surface gestures, structure and surface gestures, or neither…

Does complexity make multilingualism special? Since there is no unequivocal notion of complexity on which researchers agree, several characteristics that have been considered crucial for complexity are brought to bear on multilingualism. While multilingualism is fairly complex in some senses, for instance, because it requires that many variables…

Over the last two decades, researchers have portrayed quality professional development for mathematics teachers as collaborative and situated in teachers' instructional realities. However, empirical findings also point out various impediments to transforming teacher conversations into consequential learning. These findings illuminate the need to…

How do classroom exchanges shape the developing forms and functions of literacy learning and teaching as students transition across the years of schooling? We explore this question using excerpts from literacy lessons from primary and secondary classrooms, showing how lesson exchanges develop as trajectories connecting different forms of 'knowing'…

Knowing when the brain learns is crucial for both the comprehension of memory formation and consolidation and for developing new training and neurorehabilitation strategies in healthy and patient populations. Recently, a rapid form of offline learning developing during short rest periods has been shown to account for most of procedural learning,…

Procrastination is a delay in an intended course of action and, thus, a self-regulation failure hindering growth and well-being. Contrarily, self-regulation is a set of cognitive and metacognitive skills and strategies supporting goal-directed behavior. There is ongoing discussion regarding the extent to which (and the ways in which) promoting…

Background: Mathematics homework is highly prevalent in East Asia. Teachers and parents expect mathematics homework to improve students' performance; however, studies have not clearly defined the effectiveness of the assignment of different amounts of homework. Aims: This study analyses the differential effect of homework amount on various facets…

The whole, consisting of interconnected and interacting parts that come together for a purpose, is called a system. Every system has subsystems, vitally connected to each other and interacting. However, each of them forms a whole within itself. Generally, entities in nature are grouped into three main categories: natural systems, mechanical…

Resonance is a fundamental chemistry concept first introduced to students in General Chemistry I (GCI), reintroduced in Organic Chemistry I (OCI), and then utilized throughout other higher-level chemistry courses. Student difficulties with resonance are well documented. Instruction is one potential source of student difficulties. What instructors…

Sign language learners with a spoken language background face the challenge of acquiring a second language in a different modality. In the course of this endeavor, one of the modality-specific phenomena they encounter is the use of classifier predicates, also known as depicting signs. Classifier predicates contain a meaningful hand configuration…

Student teams are routine in business education, yet instructors lack research-based strategies to promote personal learning in teams. Our study's purpose therefore is to investigate how a dual emphasis on social identity and individual autonomy in teams may enhance students' personal learning. In a study of 557 business undergrads in 215 teams,…

The purpose of this study was to investigate the collaborative dialogue patterns of pair programming and their impact on programming self-efficacy and coding performance for both slow- and fast-paced students. Forty-six postgraduate students participated in the study. The students were asked to solve programming problems in pairs; those pairs'…
