The Use and Effectiveness of Palmtop Computers in Education

This paper reports how palmtop computers were used in an English secondary school over the course of a year. In particular, it concentrates on the perceived effectiveness of such computers in an educational setting, and on how teachers' and students' knowledge and use of "content-free" applications increased over that time. The benefits and potential problems with this new technology are discussed along with the consequences it has for classroom and school organisation.     

Time limits in testing: An analysis of eye movements and visual attention in spatial problem solving

Individuals with an aptitude for interpreting spatial information (high mental rotation ability: HMRA) typically master anatomy with more ease, and more quickly, than those with low mental rotation ability (LMRA). This article explores how visual attention differs with time limits on spatial reasoning tests. Participants were assorted to two groups based on their mental rotation ability scores and their eye movements were collected during these tests. Analysis of salience during testing revealed similarities between MRA groups in untimed conditions but significant differences between the groups in the timed one. Question‐by‐question analyses demonstrate that HMRA individuals were more consistent across the two timing conditions (κ = 0.25), than the LMRA (κ = 0.013). It is clear that the groups respond to time limits differently and their apprehension of images during spatial problem solving differs significantly. Without time restrictions, salience analysis suggests LMRA individuals attended to similar aspects of the images as HMRA and their test scores rose concomitantly. Under timed conditions however, LMRA diverge from HMRA attention patterns, adopting inflexible approaches to visual search and attaining lower test scores. With this in mind, anatomical educators may wish to revisit some evaluations and teaching approaches in their own practice. Although examinations need to evaluate understanding of anatomical relationships, the addition of time limits may induce an unforeseen interaction of spatial reasoning and anatomical knowledge.

“Asking,Learning, Seeking Out”: An Exploration of Data Literacy for Teaching

Abstract

The current study explored preservice and inservice teachers’ perspectives on data literacy for teaching. Semi-structured interviews were employed with 12 teacher candidates in elementary and special education. The findings revealed participants’ misconceptions regarding formative and summative data; their understanding of the value of formative data; perceptions of challenges related to data literacy for teaching including time, making sense of data, and reliability and validity; and candidates’ preferences for authentic data literacy instruction.     

Racial/ethnic differences in Medicaid expenditures on psychotropic medications among maltreated children

This study quantifies racial/ethnic differences in Medicaid expenditures on psychotropic drugs among a national sample of children with suspected maltreatment. We linked 4,445 child participants in the National Survey of Child and Adolescent Well-Being (NSCAW) – consisting of children investigated for suspected abuse and neglect – to their Medicaid claims obtained from 36 states. We used propensity score matching to construct a comparison group of children without known child welfare involvement, and estimated two-part generalized linear models to examine differences in annual psychotropic drug expenditures per child between children of different races/ethnicities. When compared to a matched sample of children, African American and Latino children incur $292 and $144 less expenditures on psychotropic drugs, respectively, than white children. Among NSCAW children alone, African American children display $614 less spending on psychotropic drugs when compared to white children. Racial/ethnic differences in expenditures on psychotropic drugs occur among all children on Medicaid, but the differences are especially pronounced among African American children in contact with the child welfare system. These findings demonstrate that policymakers will need to pay special attention to the needs of children of color as Medicaid expansions proceed nationwide.     

Academic essay writing as imitative problem solving: examples from distance learning

Students in tertiary education are often faced with the prospect of writing an essay on a topic they know nothing about in advance. In distance learning institutions, essays are a common method of assessment in the UK, and specified course texts remain the main sources of information the students have. How do students use a source text to construct an essay? The present paper presents a methodology for mapping the source text on to the finished student essay. The underlying assumption is that students are using a form of imitative problem solving when faced with the complex task of writing an essay. Twenty-two essays written by Open University students in the UK, based on three different questions, were analysed on the basis of the order in which novel concepts were introduced and the extent to which this order mirrored that of the source textbook. Correlations were then carried out between the structure of the essay, the structure of the source text and the eventual grade awarded. The average correlation for all three essays and source texts was 0.8, with some individual essays having a correlation of 0.98, demonstrating that the students were closely imitating the argument structure of the source text.     

Craft and Narrative in DIY Instructions

This article examines tutorials from the Web site, Instructables.com, to highlight the rhetorical possibilities of including personal narratives in instructions. The narratives in these tutorials offer detailed accounts of their authors’ experiences when constructing their projects, thereby functioning as accounts of the authors’ craft knowledge. Pitched to amateur hobbyists, rather than the professional audiences of many forms of conventional technical communication, these tutorials offer new ways of teaching craft knowledge and techniques.
