This investigation presents students with the challenge of determining the total number of eggs in a photograph of a stack of egg trays. The perspective of the photograph does not allow students to count all the individual eggs in the top tray but does allow them to see the number of eggs in one row and one column of the top tray. During this…

The solution of simple kinetic equations is analyzed without referencing any topic from differential equations or integral calculus. Guided by the physical meaning of the rate equation, a systematic procedure is used to generate an approximate solution that converges uniformly to the exact solution in the case of zero, first, and second order…

Between 10% and 15% of people with a learning disability have behaviour that challenges others, and half of these people live within the family home (Emerson et al., "Research in Developmental Disabilities," 2001; 22, 77). Current best practice in managing challenging behaviour combines person-centred planning, functional analysis, and…

Card and Giuliano's National Bureau of Economic Research (NBER) working paper on universal screening is discussed. This commentary provides a brief summary and critique of the article, proposes an explanation of the results in light of the author's research on the role of nominations or screening tests in the gifted identification process, and…

Ill-structured problems can be regarded as one of the measures that meet recent social needs emphasizing students' abilities to solve real-life problems. This study aimed to analyze the mathematical abstraction process in solving such problems, and to identify the mathematical abstraction level ([I] Recognition of mathematical structure through…

The author revisits autoethnographic work in order to examine how she unwittingly incorporated damage-centered (Tuck 2009) research approaches that reproduce settler colonial understandings of marginalized communities. The paper examines the reproduction of settler colonial knowledge in ethnographic research by unearthing the inherent surveillance…

Help seeking is an important process in self-regulated learning (SRL). It may influence learning with intelligent tutoring systems (ITSs), because many ITSs provide help, often at the student's request. The Help Tutor was a tutor agent that gave in-context, real-time feedback on students' help-seeking behavior, as they were learning with an ITS.…

Teacher education programs typically teach novices about one part of teaching at a time. We might offer courses on different topics--cultural foundations, learning theory, or classroom management--or we may parse teaching practice itself into a set of discrete techniques, such as core teaching practices, that can be taught individually. Missing…

Screen inferiority in performance and metacognitive processes has been repeatedly found with text learning. Common explanations for screen inferiority relate to technological and physiological disadvantages associated with extensive reading on screen. However, recent studies point to lesser recruitment of mental effort on screen than on paper.…

Reduction is one of the key techniques used for problem-solving in computer science. In particular, in the theory of computation and complexity (TCC), mapping and polynomial reductions are used for analysis of decidability and computational complexity of problems, including the core concept of NP-completeness. Reduction is a highly abstract…

The main goal of the Russian professional education becomes the preparation of competent, qualified graduates, who are able not only to put their knowledge and skills to use, but also make original nonstandard decisions in the situations happening in their professional activities. The process of the design students' creativity development requires…

Introducing challenging tasks in such a way that makes them accessible, rather than daunting, to students is a challenge for teachers. Solving challenging tasks involves students having to grapple with the problem. The role of the teacher is to motivate and clarify the problem rather than showing students how to solve the problem.

How do high school students approach academic and creative challenges? This study compares the content of academic and creative challenges for 190 high school students, and examines students' intentions to persist. Students reported experiencing academic and creative challenges in different areas: academic challenges were described primarily in…

The relative age effect (RAE) has been demonstrated in many youth and professional sports. In this study, we hypothesized that there would also be a RAE among youth chess players who are typically involved in a complex cognitive task without significant physical requirements. While typical RAEs have been observed in adult chess players, in this…

Nowadays information and telecommunication technologies are becoming more and more developed. It especially attracts and captures the young--young scientists, teachers and students. The purpose of the article is to highlight the experience of implementing problem-based learning technology in the traditional system of teaching medical disciplines.…
