The number line has been proposed as a central construct used by students to solve a range of mathematics problems. Given the capacity of number lines to represent all real numbers and to be used in a variety of contexts, there have been calls to increase the use of number lines in mathematics instruction. However, due to the recency of these…

Lifeguards engage in a continuous process of deciding whether swimmers are in danger or not. The variety of behaviours that distressed swimmers show makes it difficult to impart declarative knowledge to this effect during lifeguard training. As an alternative, we propose a novel training tool that requires novice participants to rapidly categorise…

This paper traces the origins of the scaffolding construct, placing it in its theoretical-historical context. The paper discusses the connection between Vygotsky's Zone of Proximal Development (ZPD), and the notion of scaffolding, and explicates the differences between scaffolding and scaffolds. The paper then presents a discussion of the changes…

Instructors manage several tensions as they engage students in defining, conjecturing, and proving, including building on students' contributions while maintaining the integrity of certain mathematical norms. This paper presents a case study of a teacher-researcher who was particularly skilled in balancing these tensions in a laboratory setting.…

Despite metacognition's profound effects in research classrooms, such research might have a very limited influence on mainstream classrooms. This may stem from a lack of comprehensive and practical pedagogy that classroom teachers can adapt for metacognition instruction as researchers do. To address this problem, this study developed a pedagogy of…

Knowledge activation and knowledge building are essential for reading comprehension. Yet, how can teachers support students in accessing and applying their existing knowledge and experiences during reading? This article provides six evidence-based principles to consider during literacy instruction, which are drawn from a recent systematic…

We studied aspects of undergraduate STEM majors' mathematical reasoning as they engaged in mathematically modeling a predator-prey scenario. The study used theoretical viewpoints on quantitative reasoning to inform scaffolding moves that would assist modelers in overcoming blockages to their mathematization of real-world problems. Our contribution…

Block-based programming environments have become increasingly commonplace in computer science education. Despite a rapidly expanding ecosystem of block-based programming environments, text-based languages remain the dominant programming paradigm outside of educational contexts, motivating the transition from block-based to text-based programming.…

A large-scale (n = 1323) survey of mnemonic recall, self-reported familiarity, cued explanation, and application by introductory statistics students was conducted at a large research university in the southeastern United States. The students were presented 14 mnemonics during the fall 2017 term. Different nonoverlapping cohorts of students were…

Visual problem-solving is an essential skill for professionals in various visual domains. Novices in these domains acquire such skills through interactions with experts (e.g., apprenticeships). Experts guide novice visual problem-solving with scaffolding behaviours. However, there is little consensus about the description and classification of…

This article using a persuasive writing example to showcase how digital technologies can be used to support all students, especially emerging bilingual learners, as they learn genre-specific norms for writing.

This dissertation focuses on strategies and techniques to enhance code comprehension skills among students enrolled in introductory computer science courses (CS1 and CS2). We propose a novel tutoring system, "DeepCodeTutor," designed to improve the code comprehension abilities of novices. DeepCodeTutor employs scaffolded self-explanation…

This paper is written as a guide for any instructor seeking to develop the mathematical modeling process or open-ended problem solving in their courses. We describe a pedagogical approach to create mini modeling problems to develop the modeling process. These are problems that fall between traditional homework problems and open-ended modeling…

This article describes a comprehensive framework (iDISC) for the close reading of informational texts for elementary students that may need additional language, social, memory, or behavioral supports. The article introduces concrete tools that are used before, during, and after close reading, including cue-cards, language stems, discussion…

This qualitative study examined the written responses of 58 undergraduate, preservice teachers in three online children's literature courses to the graphic novel, When stars are scattered by Victoria Jamieson and Omar Mohamed. Findings from a summative content analysis of participants' written responses showed five response themes: Connections…
