Standards for mathematics teaching require teachers to employ teaching practices that promote justification of mathematical ideas. This expected teaching practice is situated in substantial research on students' and teachers' difficulties with justifying mathematical ideas. This study shows different ways elementary school students in grades three…

This paper uses a multilevel analysis of mathematical reasoning rooted in Cultural Historical Activity Theory to examine how mathematical discourse and student reasoning about linear functions developed across 3 weeks in a ninth grade bilingual algebra class. Despite the teacher's expertise teaching with a conceptual focus, and her stated…

Students' understanding about analogy was investigated after a CORE learning cycle general chemistry experiment. CORE (Chemical Observations, Representations, Experimentation) is a new three-phase learning cycle that involves (phase 1) guiding students through chemical observations while they consider a series of open-ended questions, (phase 2)…

Educators working to achieve changes in classroom teaching practices that lead to improvement in student learning need to gain clarity in where they are going--what they want to accomplish. Teachers in a professional learning community need a road map as they begin learning and applying a new practice to ensure they reach their intended goal…

Feedback literature identifies mindful cognitive processing of (peer) feedback and (peer) feedback characteristics--as well as the presence of justifications for feedback--as important for its efficiency. However, mindful cognitive processing has yet to be operationalized and investigated. In this study, an operationalization of mindful cognitive…

Diagnostic reasoning is considered to be based on the interaction between analytical and non-analytical cognitive processes. Gut feelings, a specific form of non-analytical reasoning, play a substantial role in diagnostic reasoning by general practitioners (GPs) and may activate analytical reasoning. In GP traineeships in the Netherlands, trainees…

The role of analogies and metaphors has played a significant part in the work on teaching and learning science. This commentary discusses three papers from this current issue that cover a wide range of studies in the spirit of conceptual metaphors--ranging from a study somewhat similar to "classical" conceptual change, to a teacher…

Adolescents with autism spectrum disorder often do not have access to crucial peer social activities. This study examines how typically developing adolescents evaluate decisions not to include a peer based on disability status, and the justifications they apply to these decisions. A clinical interview methodology was used to elicit judgments and…

The State Title I, Part D (Part D) coordinator or other administrators of Part D programs have a focus on improving outcomes for children and youth. One way of outlining these goals and the path to achieving them is through the use of a logic model. This guide describes what a logic model is, outlines why and how a logic model can be useful, and…

In this article I examine three examples of philosophical theories of scientific representation with the aim of assessing which of these is a good candidate for a philosophical theory of scientific representation in science learning. The three candidate theories are Giere's intentional approach, Suárez's inferential approach and Lynch and…

Analogical reasoning involves the comparison of pictures as well as the memorisation of relations. Young children (4-7 years old) and students with moderate intellectual disability have a short memory span, which hampers them in succeeding traditional analogical tests. In the present study, we investigated if, by providing external memory hints,…

Placed in the larger context of broadening the engagement with systems dynamics and complexity theory in school-aged learning and teaching, this paper is intended to introduce, situate, and illustrate--with results from the use of network supported participatory simulations in classrooms--a stance we call "embedded complementarity" as an…

While video games have become a source of excitement for educational designers, creating informal game experiences that players can draw on when thinking and reasoning in non-game contexts has proved challenging. In this paper we present a design principle for creating educational video games that enables players to draw on knowledge resources…

This study invited small groups to make several arguments by analogy about simple machines. Groups were first provided training on analogical (structure) mapping and were then invited to use analogical mapping as a scaffold to make arguments. In making these arguments, groups were asked to consider three simple machines: two machines that they had…

Natural selection is one of the most famous metaphors in the history of science. Charles Darwin used the metaphor and the underlying analogy to frame his ideas about evolution and its main driving mechanism into a full-fledged theory. Because the metaphor turned out to be such a powerful epistemic tool, Darwin naturally assumed that he could also…
