Background: Children who have a combination of language and developmental disabilities with autism often experience major difficulties in learning relations between objects and their graphic representations. Therefore, they would benefit from teaching procedures that minimize their difficulties in acquiring these relations. This study compared two…

This study was designed to explore the way that use of theory influenced a social worker's conceptualization of a simulated case. The participant in this case study was a woman employed in child welfare, who holds an MSW. She was chosen because her response in a larger study represented a deviant case. Data analysis included both thematic analysis…

We engage in a metalogue based on eight papers in this issue of "Cultural Studies of Science Education" that review the state of conceptual change research and its possible affect on the teaching and learning of science. Our discussion addresses three aspects of conceptual change research: theoretical, methodological, and practical, as we discuss…

J. Kagan (2008) urges contemporary developmentalists to (a) be cautious when attributing conceptual knowledge to infants based on looking-time performance, (b) constrain their interpretation of infant performance with multiple methodologies, and (c) reconsider the possibility that qualitative development may be the path by which perceptual infants…

We often look for a best-fit function to a set of data. This article describes how a "pretty good" fit might be better than a "best" fit when it comes to promoting conceptual understanding of functions. In a pretty good fit, students design the function themselves rather than choosing it from a menu; they use appropriate variable names; and they…

This is a study of David, a senior enrolled in a high school precalculus course. David's understandings of functions and periodicity was explored, through clinical interviews and contextualized through classroom observations. Although David's precalculus class was traditional his understanding of periodic functions was unconventional David engaged…

Mother-child conversations about pictures systematically differ from mother-child conversations about objects: Pictures are more likely than objects to elicit talk about kinds, whereas objects are more likely than pictures to elicit talk about individuals. The purpose of the current study is to examine whether this difference between pictures and…

The purpose of this study is to understand in what ways a technology-enhanced learning (TEL) environment supports learning about the causes of the seasons. The environment was designed to engage students in five cognitive phases: Contextualisation, Sense making, Exploration, Modeling, and Application. Seventy-five high school students participated…

This article presents a portrait of interdisciplinarity in the Quebec school system. Following a contextual overview of this system, including its sociohistorical evolution and current organization in order to define the problem of interdisciplinarity, a second section, beginning with a clarification of terms related to interdisciplinarity,…

Online discussions enabled preK-12 teachers (n = 125) from five nations (Brazil, Colombia, Ecuador, Paraguay, and the United States) to share their perspectives of culture and citizenship and the intersections of those concepts. Discussion moved between elements of personal and others' theory into effects of theory on practice. Teachers identified…

The Teaching for Transformative Experiences in Science (TTES) model is designed to foster transformative experiences (e.g., experiences with science content involving the application of that content in ways that expand perception and value in everyday experience). This study presents a case study of a high school biology teacher learning to…

This study was conducted to investigate how students approach the learning of thermochemistry, what the challenges are and how instruction can make learning of thermochemistry more accessible. Specifically, this study seeks to understand: 1) which topics in thermochemistry are more difficult to learn and which topics are easier; 2) why the…
