This research aimed to: (1) investigate the components and indicators of computational thinking learning experience management competency of early childhood teachers in educational institutions under the Office of the Basic Education Commission; and (2) examine the congruence of these components and indicators. The research was conducted in two…

In this paper, we have combined a pragmatic and a sociocultural perspective on how artifacts are used in technical problem-solving. With these perspectives we explore how three mechanical engineering students build a plastic spider together, using instructions they found on the internet. Ten hours of video recordings were selected for a detailed…

This article examines what constitutes a 'good' mathematical problem and proposes to conceptualize the notion of "collective mathematical problems" as phenomena that arise through and by way of the inter-actions enabled by the collective itself. The author examines how these collective mathematical problems can emerge in the classroom…

The chromatographic separation of plant pigments is one of the most popular and visually appealing experiments encountered by young scientists when they are introduced to the principles of analytical chemistry. As such, it has found widespread application in schools, public engagement activities, and undergraduate laboratories. However, most of…

The importance of mathematical problem posing has been acknowledged by many researchers. In this theoretical paper, we want to capture different meanings and aspects of problem posing by approaching it from three different levels: (1) by comparing definitions, (2) by relating it to other constructs, and (3) by referring to research and teaching…

Word problems are frequently used in school mathematics to offer students the opportunity to explore mathematical relationships and structure. However, previous studies have reported that word problems are misused or abused in ways that overlook the original intent of exploring mathematical structure and relationship. This study aims to share a…

In this study, it was aimed to examine the probability problems which were posed based on continuous sample space and discrete sample space. Participants of the study consisted of 48 university students selected by using the convenience sampling method. Eight tasks related to continuous and discrete variables were designed by the researcher. Eight…

Drawing bar diagrams has been shown to improve performance on mathematical word problems wherein the relational keyword is consistent with the required arithmetic operation. This study extends this by testing the effectiveness of bar diagram drawing for word problems with an inconsistent keyword-arithmetic operation mapping. Seventy-five fifth…

In this article, the authors define numberless math stories and highlight three strategies for supporting equitable problem solving: (1) The Turn-and-Tell Strategy; (2) Storyboard and Story Mat; and (3) The Act-It-Out Strategy. These three strategies open up problem solving and give every student access to a challenging mathematics curriculum…

The nature of the development of arithmetic performance has long been intensively studied, and available scientific evidence can be evaluated and synthesized in light of Nelson and Narens' model of metacognition. According to the Nelson-Narens model, human cognition can be split into two or more interrelated levels. Obviously, in the case of more…

This study forms part of a classroom teaching experiment on the development of a group of 25 9-10 years old students' algebraic thinking. More specifically, it explored their reasoning while solving word problems built around functional relationships to determine how they generalized through questions posed using natural language, drawn figures or…

This review maps patterns in research on Challenge Based Learning (CBL) in higher education (HE) between 2009 and 2020. How is CBL defined in HE settings? How is CBL in HE grounded scientifically in the research? The results show a shift of CBL from being a concept coined by a multinational technology company targeting learning in schools, to…

This program model describes the phases of planning, implementing, and evaluating a program designed for Tennessee public schools to manage student behavior in at-risk populations. This program model employs a hybrid asset-based community development, logic, and interactive model to implement interventions based on the principles of applied…

The purpose of this study was to explore the paths by which word-problem intervention, with versus without embedded prealgebraic reasoning instruction, improved word-problem performance. Students with mathematics difficulty (MD; n = 304) were randomly assigned to a business-as-usual condition or 1 of 2 variants of word-problem intervention. The…

Research on mathematical problem solving has a long tradition: retracing its fascinating story sheds light on its intricacies and, therefore, on its needs. When we analyze this impressive literature, a critical issue emerges clearly, namely, the presence of words and expressions having many and sometimes opposite meanings. Significant examples are…
