Exploiting Online Interactivity to Enhance Assignment Development and Feedback in Distance Education

Networking provides the means to deliver enhancements to assignment development and feedback which have not previously been possible for ODL courses. This paper describes the experimental introduction and evaluation of network delivered model answers and peer review as additional formative feedback on assessment. The enhancements assisted students in attuning themselves to the writing demands of the course, and there may be particular times in a course when they are most of value. Use of a network allowed for delivery within a controlled time frame, whilst providing an interactive environment for debate on alternative perspectives.     

Transtheoretical-based bullying prevention effectiveness trials in middle schools and high schools

Background Bullying threatens the physical and mental well-being of students across a broad range of schools. Tailored interventions based on the Transtheoretical model and delivered over the Internet were designed to reduce participation in each of three roles related to bullying (bully, victim and passive bystander).

Methods Effectiveness trials were completed in 12 middle schools and 13 high schools in the USA. A diverse sample of 1237 middle (6th–8th grade, with 45.1% in the 7th grade; ages 11–14) and 1215 high school (9th–11th grade, with 41.6% in the 9th grade; ages 14–17) students were available for analyses.

Results Analyses showed significant treatment effects for both intervention groups when compared to control for both the middle and high school programs.

Conclusions Given the relative ease of dissemination, these programs could be applied as stand-alone practices or as part of more intensive interventions.     

The new inset: a transformation scene

The work of Lawrence Stenhouse strongly promoted the view that curriculum development was dependent upon teacher development and as such, has had a great impact on the in‐service education of teachers. Such a teacher‐centred model is now called in question by recent DES moves in relation to the funding and control of INSET. By exploiting the mechanisms of categorical funding, as refined by the MSC, it seems likely that the Department will be able to impose a conception of ‘curriculum led staff development’, which originated in Further Education. Such a conception assumes that curriculum is a given and that the development needs of teachers may be deduced from it, thus increasingly restricting them to the business of execution and not of conception.     

Influences of orthographic consistency and reading instruction on the development of nonword reading skills

Wimmer and Goswami (1994) report that seven-, eight-, and nine-year old English children had considerably more difficulties with a nonword reading task than German children who acquire an orthography with highly consistent grapheme-phoneme correspondences. In Study 1, seven-, eight-, and nine year old English children receiving a phonics instruction were presented with the same task and compared with the children tested by Wimmer and Goswami. Study 2 is a replication with different samples of English children receiving the standard electic approach combining both whole-word and phonics strategies, English children receiving a phonics teaching approach and German children who are taught via phonics methods and acquire a consistent orthography. Children from Grades 1 to 4 were tested. In both studies, the English phonics children read the nonwords with almost the aame accuracy and speed as the German children. In Study 1, the English phonics children performed clearly better on nonword reading than the English standard sample. In Study 2, this difference was also evident but less marked. In Grade 1 English phonics as well as English standard children had clearly more difficulties with phonological decoding than German children indicating a relevant influence of orthographic consistency.     

The Impact of Doctoral Study on Marital Satisfaction

The purpose of the study was to determine whether marital relationships of doctoral students were affected while they were enrolled in graduate programs. The stratified sample consisted of 54 participants who completed the Demographics and Structured Questionnaire, Locke‐Wallace Marital Adjustment Test, and Index of Marital Satisfaction. There were no significant differences among the marital satisfaction levels of graduate students at different stages in their program. Significant differences were found in relationship to several of the research questions, however. Specifically, a significant difference was found in the marital satisfaction of couples involved in marital therapy. Spouses who also were students scored significantly higher in marital satisfaction than spouses who were not students. Areas of discord that affected marital satisfaction during graduate school were philosophy of life, demonstration of affection, and sexual relations.     

Play centers that encourage literacy development

Teachers are always searching for fresh ideas that address children's growth needs. Ideas that provide learning opportunities which are developmentally appropriate are particularly welcomed. using play as a medium for facilitating literacy growth is one such opportunity. We know from current theory, research and practice that sociodramatic play contributes to children's learning. Its importance in the development of literacy skills has also been investigated and affirmed. See Christie, 1991; Dodge & Frost, 1986; Fisher, 1991; Isenberg & Jacob, 1985; Morrow, 1989, 1990; Morrow & Rand, 1991; Pellegrini, 1980; Rogers & Sawyers, 1988; Schickendanz, 1986; Woodard, 1984.     

High-Resolution Ultrasonic Imaging of Artworks with Seismic Interferometry for Their Conservation and Restoration

Artworks are an inseparable part of the cultural heritage of societies and provide us with a unique look at cultural developments through time and space. For the best possible conservation, it is paramount to know the constituent materials, condition, and construction techniques of the objects (e.g. painting on wood, fresco, sculpture). Such information is required not only for the surfaces of the objects, but also for the interiors; in the imaging discipline, this is known as depth imaging. Here, we introduce a new method for non-invasive depth imaging as an alternative to traditional non-invasive methods when the latter cannot be used to obtain the required information. We use ultrasonic transverse-wave transmission measurements and turn them into virtual reflection measurements. We achieve this by applying seismic interferometry with active sources. Obtaining reflection measurements by seismic interferometry allows us to apply an advanced imaging technique – prestack depth migration, as used in seismic exploration – to produce a high-resolution depth image of an object. We apply our method to ultrasonic data recorded on a mockup of a painting on a wooden support. We validate our method by comparing our results with an image from X-ray computed tomography.
