ICT and educational (dis)advantage: families,computers and contemporary social and educational inequalities

Because access to new technologies is unequally distributed, there has been considerable debate about the growing gap between the so‐called information‐rich and information‐poor. Such concerns have led to high‐profile information technology policy initiatives in many countries. In Australia, in an attempt to ‘redress the balance between the information rich and poor’ by providing ‘equal access to the World Wide Web’ (Virtual Communities, 2002 Virtual Communities (2002) About us. Available online at: http://www.virtualcommunities. com.au (accessed 18 August 2002)  [Google Scholar]), the Australian Council of Trade Unions, Virtual Communities (a computer/software distributor) and Primus (an Internet provider) in late 1999 formed an alliance to offer relatively inexpensive computer and Internet access to union members in order to make ‘technology affordable for all Australians’ (Virtual Communities, 2002 Virtual Communities (2002) About us. Available online at: http://www.virtualcommunities. com.au (accessed 18 August 2002)  [Google Scholar]). In this paper, we examine four families, one of which had long‐term Information and Communication Technologies (ICT) access, and three of which took advantage of the Virtual Communities offer to get home computer and Internet access for the first time. We examine their engagement with ICT and suggest that previously disadvantaged family members are not particularly advantaged by their access to ICT.     

The effect of towing a range of relative resistances on sprint performance

The aim of this study was to compare sprint performance over 10 and 20?m when participants ran while towing resistances, weighing between 0 and 30% of body mass. The sample of 33 participants consisted of male rugby and soccer players (age 21.1?±?1.8 years, body mass 83.6?±?13.1?kg, height 1.82?±?0.1?m; mean?±?s). Each participant performed two sets of seven sprints over 20?m using a Latin rectangular design. The times were recorded at 10 and 20?m using electronic speed gates. The sprints of 13 players were video-recorded to allow calculation of stride length and frequency. For both sprints, a quadratic relationship was observed between sprint time and resistance as sprint time increased from 2.94?s to 3.80?s from 0 to 30% resistance. This relationship was statistically significant but considered not to be meaningful for performance because, over the range of resistances used in this study, the quadratic model was never more than 1% (in terms of sprint time) from the linear model. As resistance increased, the stride length shortened, with mean values of 1.63?±?0.13?m at 0% body mass and 1.33?±?0.13?m at 30% of body mass. There was no significant change in stride frequency with increasing resistance. The results show that in general there is an increase in sprint time with an increase in resistance. No particular resistance in the range tested (0?–?30%) can be recommended for practice.     

Using Food Science Demonstrations to Engage Students of All Ages in Science,Technology, Engineering,and Mathematics (STEM)

Abstract: The overarching goal of the Science, Technology, Engineering, and Mathematics (STEM) Education Initiative is to foster effective STEM teaching and learning throughout the educational system at the local, state, and national levels, thereby producing science literate citizens and a capable STEM workforce. To contribute to achieving this goal, we have assembled six food science demonstrations for use at all educational levels and have presented these lessons to students at the elementary through higher education levels. The focus of this article is to share these food science demonstrations and our experiences using them so that others can use them for engaging students in STEM disciplines, through food science, at any educational level. Featured demonstrations include: (1) liquid nitrogen ice cream: a matter of changing phases, (2) seeing our senses work together, (3) whipping up the cream, (4) milk versus dark: what is the difference?, (5) counting calories by burning them, and (6) culinary spherification: the wonders of cross‐linking. Overall, our experience with using these demonstrations has been very positive. Students appear engaged in the learning process and love to consume the demonstration end products. Downloadable handouts containing demonstration details for each demonstration are available as supporting information.     

Predictors of parents' physical disciplinary practices.

OBJECTIVE: This study examined how childhood history of discipline (1) related to ratings of how severe and typical punishments were; and (2) predicted parents' use of discipline techniques. The influence of child culpability on these ratings was also investigated. METHOD: Ninety-nine New Zealand parents rated 12 physical discipline scenarios varying in discipline severity and perceived child culpability. Parents judged how severe and typical they considered the disciplines depicted in the scenarios and reported on how often they had experienced such discipline as children and how often they had used them with their own children. RESULTS: When the child was perceived to be at fault, parents rated the discipline depicted as less severe, considered the technique more typical, reported they had been similarly disciplined more frequently, and applied such discipline to their child more frequently. Childhood history of a discipline was related to the parent's use of that method, and the parents judged techniques they used with their own children as less severe and more typical of methods of discipline. History of discipline and severity judgments were the best predictors of parents' disciplinary practices. CONCLUSIONS: Although the findings support the cycle of violence theory, more complex potential pathways to abusive parenting, including the variables in this study, are proposed.     

The “learning disabilities” label: An experimental analysis

The “learning disability” label is a relatively new addition to the field of special education and its effects have begun to be investigated. This study examined the differences produced by two categorical labels on students impressions of the “disturbingness” of behavior and their willingness to work with the labeled child. Aggressive behaviors thought to be exhibited by learning disabled youngsters were rated differently from identical behaviors thought to be exhibited by emotionally disturbed children. Implications of this study suggest that the “LD” label may connote a milder form of disability; and that teacher and professional training institutions should consider the deleterious effects labels may convey with regard to expected behaviors.
