Interviews with fourth grade students about their writing in science revealed their perspectives on purposes for writing, understandings of intended audiences, and use of visuals. A discussion of these themes is situated in a consideration of theory and research on genre. The article includes suggestions for teachers related to the teaching of…

Expert mathematicians are contrasted with undergraduate students through a two-part analysis of the potential and actual use of visual representations in problem solving. In the first part, a classification task is used to indicate the extent to which visual representations are perceived as having potential utility for advanced mathematical…

Visual ethnographers increasingly use hypermedia for research, representation and teaching and learning. This article discusses these uses by reflecting on Visualising ethnography, a teaching and learning 'gateway' web site about the visual in the ethnographic process housing interviews, authored works, exhibitions, introductory texts and links.…

The teaching units within the National Science Strategy can be summarised diagrammatically. Presentation in this format makes it easier for teachers and students to visualise progression routes through Key Stage 3. An example is given for the key idea of cells. (Contains 1 figure.)

In this article, the author demonstrates that the semiotic model proposed by Charles Morris enables us to optimize our understanding of technical communication practices and provides a good point of inquiry. To illustrate this point, the author exemplifies the semiotic approaches by scholars in technical communication and elaborates Morris's model…

This study utilized retrospective video analysis to distinguish sensory-motor patterns in infants with fragile X syndrome (FXS) (n=11) from other infants [i.e., autism (n=11), other developmental delay (n=10), typical (n=11)] at 9-12 months of age. Measures of development, autistic features, and FMRP were assessed at the time of entry into the…

Visual organizers are visual frameworks such as figures, diagrams, charts, etc. used to present structural knowledge spatially in a given area with the intention of enhancing comprehension and learning. Visual organizers are effective in terms of helping to elicit, explain, and communicate information because they can clarify complex concepts into…

Cinemicrography--the capture of moving cellular sequences through the microscope--has been influential in revealing the dynamic nature of cellular behavior. One of the more dramatic cellular events is mitosis, the division of sister chromatids into two daughter cells. Mitosis has been extensively studied in a variety of organisms, both…

The increasingly integrative use of images with language in many different types of texts in electronic and paper media has created an urgent need to go beyond logocentric accounts of literacy and literacy pedagogy. Correspondingly there is a need to augment the genre, grammar and discourse descriptions of verbal text as resources for literacy…

In two picture-word interference experiments we examined whether phrase boundaries affected how far in advance speakers plan the sounds of words during sentence production. Participants produced sentences of varying lengths (short determiner + noun + verb or long determiner + adjective + noun + verb) while ignoring phonologically related and…

This article talks about fulldome video, a new technology which has been adopted fairly extensively by the larger, well-funded planetariums. Fulldome video, also called immersive projection, can help teach subjects ranging from geology to history to chemistry. The rapidly advancing progress of projection technology has provided high-resolution…

The teaching of energy throws up many different approaches and causes many arguments. This paper describes yet another approach to teaching the subject matter using a system of diagrams, but hopefully one that will be an acceptable compromise for many teachers. Lord Rutherford is often quoted as saying, "All science is either physics or stamp…

PowerPoint is an inevitable technology of contemporary business presentations, a tool that is now available to virtually every office worker in the United States, but denounced by academics and by CEOs as intellectual reductionism. Requiring students to create and use electronically generated "visual aids" seems to result in a…

Two major predictors of subjective quality of life (SQOL) in adults are known to be self-esteem and a sense of primary control. Moreover, secondary control is known to be unimportant defense strategy when primary control fails. This study aimed to determine whether these relationships also apply to children. A sample of 66 children aged from 5 to…

Quantum fields are introduced in order to give students an accurate qualitative understanding of the origin of Feynman diagrams as representations of particle interactions. Elementary diagrams are combined to produce diagrams representing the main features of the Standard Model.
