Promoting problem-solving in students is an important aim of secondary science education. There is a mismatch, however, between the complex, ill-structured nature of realistic scientific problems, versus the well-structured problems students are generally confronted with. The current study investigates a teaching-learning strategy that resolves…

The study reported in this paper was part of a larger study that explored pre-service teachers' perceptions of the effectiveness of a problem-based learning (PBL) teaching approach for developing their mathematics pedagogical content knowledge (PCK) and their ability to enact their PCK in a tertiary mathematics education subject. This paper…

We are surrounded by controversy--politics, religion, diets, and even science are all up for debate in our 24/7 world of social media and the internet. With this controversy comes a lot of misinformation and competition with what our students might otherwise be learning in our classrooms. I know this intimately, since I teach fitness and nutrition…

This article revisits and expands upon a previous phenomenographic study characterising the qualitatively different ways in which South African undergraduate physics students may experience the use of +/- signs in one-dimensional kinematics (1DK). We find the original categorisation as applicable for interpreting Swedish university-level students'…

Background and Aims: Echolalia, the repetition of speech, is highly prevalent in school aged children with Autism. Prior research has found that individuals with echolalia use their repetitions to engage in communicatively functional speech, in the absence of self-generated speech. Educators are the natural audience for a wide vary of echoed…

The present study investigated the utility and validity of the Social Emotional Health Survey-Higher Education (SEHS-HE) among Turkish students (N = 345) in higher education. Confirmatory factor analysis found acceptable data-model fit statistics for "a priori" SEHS-HE latent measurement models and its second-order "covitality"…

Monte Carlo (MC) simulation is widely used in many different disciplines in order to analyze problems that involve uncertainty. Simulation decomposition has recently provided a simple, but powerful, advancement to the standard Monte Carlo approach. Its value for better informing decision making has been previously shown in the investment-analysis…

Logistic regression is one of the most fundamental tools in predictive analytics. Graduate business analytics students are often familiarized with implementation of logistic regression using Python, R, SPSS, or other software packages. However, an understanding of the underlying maximum likelihood model and the mechanics of estimation are often…

Introductory calculus-based mechanics ("Physics 1") is an important gateway course for students desiring to pursue a science, technology, engineering, and mathematics (STEM) career. A major challenge with this course is the large spread in the students' incoming physics preparation. This level of preparation is strongly predictive of a…

This study used a cross-lagged design to examine the longitudinal relations between teacher-child conflict and children's problem behavior during the preschool years based on a stratified sample of 515 Chinese preschool children. Children's problem behavior was reported by parents, and teachers rated their levels of conflict with children. Results…

The literature describes different stances concerning the focus on how mathematics should be taught, with some preferring a conceptual knowledge approach and others a procedural knowledge approach. The current study investigated the relationship between students' conceptual and procedural knowledge in a calculus context. To better understand the…

Using the data from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011), this paper proposes to theoretically redefine and empirically capture the concept of emotional capital as it applies to students, employing five components (engagement, school belonging, grit, peer social support, and life satisfaction). The…

The purpose of this study was to examine how pre-service mathematics teachers (PMTs) integrated a dynamic geometry environment (DGE) into their reasoning process while solving geometric locus problems. Task-based interviews based on the locus problems were conducted with eight PMTs working in pairs. The PMTs could use a computer with access to…

An essential task for mathematics teachers is posing problems. Selecting mathematics problems that develop mathematical proficiency and engage students in desirable mathematical practices is a critical decision-making process. We present the Framework for Posing Elementary Mathematics Problems (F-PosE) developed to focus prospective teacher…

Innovation in the design of curricula is widely discussed. Innovative curricula expose students to a diverse range of learning environments and prompt them to ask questions, stimulating their creativity and allowing them to develop a sense of initiative and to hone their problem-solving skills and ability to apply knowledge to practice. The…
