This research addressed Hungarian pre-service and in-service (both elementary and lower secondary) teachers' pedagogical content knowledge concerning the teaching of word problem solving strategies. By means of a standardized interview protocol, participants (N = 30) were asked about their judgement on the difficulty of teaching word problems, the…

The difficulties students have in blending mathematics and physics are here analyzed, by focusing on the issue of a convergent series. We present an experimental and a theoretical analysis of some phenomena which can be investigated employing series, as the bouncing marble and Zeno's paradox of Achilles and the turtle. Measurements were carried…

Purpose: The primary purpose of this study was to examine the development of past tense counterfactual (PTCF) sentences ("If the dog had stayed in the house, he would not have bitten the police officer") in young adolescents and young adults, addressing both production and comprehension.

Various reasons for underperformance in physical sciences have been found, such as a lack of teachers' content knowledge and a lack of resources. This study looks into the extent of alignment between the various levels of the curriculum on circuit electricity (intended, implemented and attained levels). The research took place in Mpumalanga…

In this article, we address the issue of targeted instruction on interpretive contrasts between native and second-language grammatical meanings. Such mismatches are predicted to create challenges for learners. We illustrate this with French and English pronouns. In French, clitic pronouns (le, la) point to human as well as inanimate referents,…

Functions is considered an important mathematical literacy concept within the Organization for Economic Cooperation and Development's (OECD's) Programme for International Student Assessment (PISA), and it has been shown that Japanese junior high school students are experiencing problems understanding functions. This paper examines the difficulty…

This study examined whether a video illustration of a complex phenomenon promoted learner interest, perceived comprehensibility, and better learning in online- and classroom-based contexts. In the first study, undergraduate participants (N = 101) viewed learning materials which contained a video only, a video and textual explanation, or a textual…

This paper describes a classroom demonstration that showcases how pre-existing beliefs (e.g., stereotypes) influence problem-solving. Across four studies, participants solved riddles with gender stereotype-consistent (e.g. doctor is male) or gender stereotype-inconsistent (e.g., doctor is female; barber is female) solutions. Solve time, perceived…

How people see the world, even how they research it, is influenced by beliefs. Some beliefs are conscious and the result of research, or at least amenable to research. Others are largely invisible. They may feel like "common knowledge" (though myth, not knowledge), unrecognized premises that are part of the surrounding culture. As we…

A prerequisite for low-stakes activities to improve learning is to keep students engaged when confronted with challenging material. Comparing a personalized and non-personalized version of computerized practising, this study experimentally evaluates the relationships between student effort and ability across different dimensions of task…

When educators provide students with opportunities to interact with educational technology such as floor-robots, it may: (a) increase students' awareness of new educational tools, and (b) enhance students' use and engagement with new technologies. This case study provided upper-elementary, Hispanic students with opportunities to engage in…

Elementary school students struggle in interpreting the equal sign as a symbol denoting equivalence. Although many have advocated using a pan-balance scale to help students develop this understanding, less is known about what features associated with this model support learning. To attempt to control and examine these features, the investigators…
