Supporting social awareness in collaborative e‐learning

In the last decade, we have seen the emergence of virtual learning environments. Initially, these environments were a little more than document repositories that tutor used unicast to the students. Informed in part by social constructivist theories of education, later environments included capabilities for tutor–student and student–student, synchronous and asynchronous communication. The initial research of this paper reports the typical low usage of these capabilities. The main research attempted to ameliorate this problem by the provision of tools to promote a sense of social awareness as self‐presence and copresence, and evaluation techniques to analyse e‐learners' interactions. Data was obtained from prepost questionnaires, log files and social network analysis which augmented the data provided by the tools embedded in Moodle. The results indicate the importance of social awareness in effective e‐learning; the quality of active participation can be increased by the use of associated tools. The e‐tutor's role is still pivotal to facilitate and to support such engagement towards collaborative learning. Implications for future research suggest that social awareness tools and evaluation techniques can create awareness cues in an interface with a potential impact on learning.     

Increasing heat storage by wearing extra clothing during upper body exercise up-regulates heat shock protein 70 but does not modify the cytokine response

Plasma heat shock protein 70 (HSP70) concentrations rise during heat stress, which can independently induce cytokine production. Upper body exercise normally results in modest body temperature elevations. The aim of this study was to investigate the impacts of additional clothing on the body temperature, cytokine and HSP70 responses during this exercise modality. Thirteen males performed 45-min constant-load arm cranking at 63% maximum aerobic power (62 ± 7%V?O_2peak) in either a non-permeable whole-body suit (intervention, INT) or shorts and T-shirt (control, CON). Exercise resulted in a significant increase of IL-6 and IL-1ra plasma concentrations (P < 0.001), with no difference between conditions (P > 0.19). The increase in HSP70 from pre to post was only significant for INT (0.12 ± 0.11ng?mL^?1, P < 0.01 vs. 0.04 ± 0.18 ng?mL^?1, P = 0.77). Immediately following exercise, T_core was elevated by 0.46 ± 0.29 (INT) and 0.37 ± 0.23ºC (CON), respectively (P < 0.01), with no difference between conditions (P = 0.16). The rise in mean T_skin (2.88 ± 0.50 and 0.30 ± 0.89ºC, respectively) and maximum heat storage (3.24 ± 1.08 and 1.20 ± 1.04 J?g^?1, respectively) was higher during INT (P < 0.01). Despite large differences in heat storage between conditions, the HSP70 elevations during INT, even though significant, were very modest. Possibly, the T_core elevations were too low to induce a more pronounced HSP70 response to ultimately affect cytokine production.     

Making Multicultural Education 'Real'

This paper outlines a problem-based approach to the teaching and learning of multicultural education for pre-service teachers at the University of Canberra during the second semester, 1999. Within the context of this research, problem-based teaching and learning will be considered as both curriculum and as a process. The curriculum consisted of carefully designed problems focusing on theoretical constructs relevant to the unit under scrutiny; the process involved problem solving, self-directed learning strategies and team participation at both the seminar and tutorial level (Gallagher, 1997). The decision to adopt this approach was driven by a need to connect practical classroom scenarios with the theoretical basis of the course. It was through the adoption of an Action Research model that these issues were explored.     

Perceptions of Co-Teaching in the Clinical Experience: How Well Is It Working?

This study examined the perceptions of teacher candidates, cooperating teachers, and university supervisors in the first year of state-mandated co-teaching in the clinical experience. Study results suggest the need (a) to emphasize the importance of the teacher candidate exerting leadership, (b) to develop and communicate specific criteria for teacher candidates to enhance their ability to take the lead in planning, organization, management, lesson delivery, and assessment during their co-teaching experience, (c) to redefine the nature of the “solo” period, and (d) to deepen the understanding of all stake holders to increase their commitment to the tenets of co-teaching.     

Settling into school: The importance of early friendships for the development of children's social understanding and communicative competence

This paper reports an exploratory study of 37 children (aged 4–5 years) throughout their first term of formal schooling. Children in two different schools were included in the study. Four pairs of friends and four isolated children were targeted for in‐depth observation every week throughout the term. The behaviour and speech of these 12 children were coded systematically in various activities and settings to assess their level of social involvement and their adjustment to school. Sociometric interviews were carried out with all 37 children. These were used to examine the pattern of social relationships in the two classes and to investigate Children's understanding of concepts such as ‘friendship’. The target children also took part in a communication game with other children from their classes, matched in age and verbal ability, but who were not friends. It was predicted that children who started school in the company of a friend or friends would have better developed social and communicative skills than children who began school without the support of existing friendships. As predicted, children who had well established friendships on entry to school gave more sophisticated reasons as to why children liked and disliked each other. These children were also more effective communicators than the isolated children. The results suggest that friendship not only plays an important part in developing young Children's social competencies, but also that it influences children'sperformance on a range of classroom‐based learning activities, particularly those which involve mutual collaboration and co‐operation.     

Dialogue and reciprocity in an international teaching practicum

Many teacher education institutions across the world are now initiating and supporting international teaching practicums to better prepare their teaching graduates to teach for diversity. Recently, some of these practicums have embedded service-learning structures and discourses to further encourage pre-service teachers (PSTs) to think beyond their self-interests towards larger ethical and educational questions. This paper employs narrative-based inquiry methods to explore the lived experiences of three co-leaders of an international teaching practicum in South Africa for Australian PSTs underpinned by dialogic service-learning principles. Using Bakhtinian dialogic theory, the authors generate alternative interpretations of reflective narratives they have written, in order to examine the concepts of dialogue and reciprocity in their lived experience of this teaching practicum. The authors conclude that reciprocity and dialogue are indeed valuable discourses for critically researching international teaching practicums with service-learning dimensions, but counsel against romanticising either of these.     

Adolescents‘ Self-Efficacy to Overcome Barriers to Physical Activity Scale

This paper describes a revised measure of self-efficacy to overcome barriers to moderate and vigorous physical activity in a sample of 484 high school students in Toronto, Ontario. The students had a mean age of 15.3 years. Principal axis factoring with oblique rotation yielded five factors: self-efficacy to overcome internal, harassment, physical environment, social environment, and responsibilities barriers. Two problematic items were removed, which resulted in a 22-item measure. Subsequent analyses were conducted on responses to this shortened measure. Confirmatory factor analysis supported the five-factor model and demonstrated age- and sexinvariance. The subscales had good internal consistency reliability. Structural regressions demonstrated a strong relationship between the resulting factors and a physical activity measure (energy expenditure), showing predictive validity.
