This study explores the ontological perspective in analyzing students' problem-solving related to mechanical energy conservation. The research involves 18 high school students whose explanations were qualitatively analyzed using an extended ontological framework. Initially, students predominantly employed matter-based predicates and…

For several decades, brainstorming in groups and its variants have been widely examined in research as a technique to produce ideas. The way to stimulate elaboration by linking ideas to those previously given by others during a brainstorming session is a challenge for researchers and practitioners aiming to go beyond idea generation. Despite…

As environmental challenges increase in scope and scale, new conceptualizations for environmental literacy are needed. Specifically, notions of environmental literacy must move from those at the individual level to those at the group, or community, level. However, the concept of community level environmental literacy is underdeveloped. In this…

This paper critically assesses the meaning of Indigenous Knowledge from a global context. Using content analysis of myriad descriptions of the concept and quasi-quantitative statistical techniques, this study examines the global elements that should be used to characterize Indigenous Knowledge. This is prompted by the fact that for decades,…

Mathematical ideas are developed and spread during argumentative whole class discussions between a teacher and her students. The goal of the current study is to characterize how ideas about quadratic functions emerge and are spread during a whole-class discussion among ninth graders. To this end, we recorded both discussions between pairs of…

Recent evidence has shown that eliciting confidence ratings can affect cognitive performance--a so-called reactivity effect. Several mechanisms have been proposed to account for reactivity, but currently there is only indirect evidence about why confidence ratings are reactive. Here, we explore the strategic changes in cognitive processes that…

Working memory (WM) is a critical cognitive system that supports processing a variety of information. Remembering different types of objects may impose different levels of cognitive demands on WM performance. In the present study, we examined 205 children's WM in representing different types of content and its developmental trajectories in early…

Hybridization is a bonding model, universally used in organic chemistry, which allows consideration of two-electron localized bonds in organic molecules. Without hybridization, it is almost impossible to describe aspects such as hyperconjugation for the stabilization of carbocations and alkane conformers. Hybridization is often presented in…

Idea generation requires the generation of many, various and novel ideas, and has the greatest impact on the quality of the final design solution within the design process. The literature offers numerous design methods and tools available for the use of designers in idea generation, though criticisms include the shortcomings of methods in…

This study investigates the impact of perceived work-related diversity on two virtual idea-generation methods (video-based oral brainstorming and virtual brainwriting) on the innovative process during both the idea-generation and selection phases. A total of 157 working students were randomly assigned to 57 small groups to complete brainstorming…

This article presents a theoretical-didactic perspective on the formation and development of concepts concerning mathematical objects as a result of research on didactic difficulties in dealing with concepts in school. The theoretical foundation that supports the research is based on the contributions of the materialist approach to the theory of…

As students have struggled to use the "chip model" (i.e., red and yellow chips representing positive and negative numbers) to model integer addition and subtraction and have found it confusing, the authors developed a series of activities based on adding and removing opposite objects to and from a boat to better help students in this…

We introduce learning modules in cryptography that can be crafted to motivate many abstract mathematical ideas, and we illustrate with a sample module. These modules can be used in a variety of ways, such as the core for a cryptography course or as motivating topics in other courses such as abstract and linear algebra or number theory.

Background: The study of emotions in engineering education (EEE) has increased in recent years, but this emerging, multidisciplinary body of research is dispersed and not well consolidated. This paper reports on the first systematic review of EEE research and scholarship. Purpose: The review aimed to critically assess how researchers and scholars…

This qualitative descriptive case study explores how genealogists describe the mechanism of epistemic change in their research, highlighting the roles of epistemological doubt, epistemological volition, and resolution strategies. It explores the integration of digital technologies in genealogical practices in the United States and their…
