Academic literacies and e-learning: A critical approach to writing in the online university

This paper adopts an academic literacies perspective to argue for a critical approach to the writing practices of the online university classroom. It describes an on-going action research project in an online Masters in Online and Distance Education (MAODE) programme at the UK Open University, which aims to create an online writing resource to support distance learners in developing a critical awareness of the writing practices on the programme. The paper presents the results of an evaluation study of this resource during the 2005 presentation of the MAODE, and discusses the evidence from this study that such a resource can provide a space for students to critique the dominant literacies of the online university.     

Denominational schools and public schooling

The author argues that the critical question in determining whether denominational schools should receive public funding is: Does the school provide an education in accordance with publicly accepted criteria for that concept and in accordance with the dominant values in society? A public system of schooling has itsraison d'être in the need to provide a common understanding. This is not incompatible with acceptance of private schools, nor, despiteprima facie oddity, is there anything incoherent about the idea of providing state funding for private schools. So far as denominational schools go, therefore, the conclusion is that they are deserving of state support provided that they do not promote values and beliefs antithetical to the larger community, and, specifically, that they do not engage in the anti-educational practice of indoctrination.     

The moderating effects of emotions on cognitive skills

An important challenge in higher education today is the growing tutor–student ratio that diminishes the ‘human touch’. As learning and teaching ultimately form an interpersonal process, this will lead to student discontent and impact on their learning. Whilst there is little that teaching practitioners can do in terms of the growing student numbers they have to tutor, they may however influence student learning by enhancing their positive emotions. This study examines the importance of emotions in improving cognitive skills and how they interact with knowledge and reflection. This research contributes to theory by examining the role of emotions as a moderating factor in the learning process. Our findings reveal that emotions moderate the direct relationship between knowledge and cognitive skills, and the indirect relationship between knowledge and cognitive skills via reflection. The findings demonstrate the critical role that emotions play in student learning. Implications for theory and practice are discussed.     

Struggling to understand abstract science topics: A Roundhouse diagram-based study

This study explored the effects of Roundhouse diagram construction on a previously low-performing middle school science student's struggles to understand abstract science concepts and principles. It is based on a metacognition-based visual learning model proposed by Wandersee in 1994. Ward and Wandersee introduced the Roundhouse diagram strategy and showed how it could be applied in science education. This article aims at elucidating the process by which Roundhouse diagramming helps learners bootstrap their current understandings to reach the intended meaningful understanding of complex science topics. The main findings of this study are that (a) it is crucial that relevant prior knowledge and dysfunctional alternative conceptions not be ignored during new learning if low-performing science students are to understand science well; (b) as the student's mastery of the Roundhouse diagram construction improved, so did science achievement; and (c) the student's apt choice of concept-related visual icons aided progress toward meaningful understanding of complex science concepts.     

So close,and yet so far: cross-racial interactions among undergraduate students in two neighboring borderland communities

This article discusses two studies on the extent and nature of cross-racial interactions (CRIs) among undergraduate students from two neighboring US–Mexico borderland communities. Of the four participating higher education institutions, two were adjacent to the US–Mexico borderline, while the other two were 45 miles away from the borderline. One study relied on survey responses from over 900 students, while the other relied on focus group data from over 30 students. The participating students were from two universities and two community colleges. Although the students shared some common experiences and attitudes, there were some marked and important differences among them. These differences made a compelling argument for localizing what diversity means and customizing efforts to foster CRIs on college campuses.     

A comparison of the physiological response to simulated altitude exposure and r-HuEpo administration

Concerns have been raised about the morality of using simulated altitude facilities in an attempt to improve athletic performance. One assumption that has been influential in this debate is the belief that altitude houses simply mimic the physiological effects of illegal recombinant human erythropoietin (r-HuEpo) doping. To test the validity of this assumption, the haematological and physiological responses of 23 well-trained athletes exposed to a simulated altitude of 2650-3000 m for 11-23 nights were contrasted with those of healthy volunteers receiving a low dose (150 IU·kg^-1 per week) of r-HuEpo for 25 days. Serial blood samples were analysed for serum erythropoietin and percent reticulocytes; maximal oxygen uptake ([Vdot]O_2max) was assessed before and after r-HuEpo administration or simulated altitude exposure. The group mean increase in serum erythropoietin (422% for r-HuEpo vs 59% for simulated altitude), percent reticulocytes (89% vs 30%) and [Vdot]O_2max (6.6% vs -2.0%) indicated that simulated altitude did not induce the changes obtained with r-HuEpo administration. Based on the disparity of these responses, we conclude that simulated altitude facilities should not be considered unethical based solely on the tenet that they provide an alternative means of obtaining the benefits sought by illegal r-HuEpo doping.
