A single session of resistance exercise does not reduce postprandial lipaemia

This study investigated the effect of a single session of resistance exercise on postprandial lipaemia. Eleven healthy normolipidaemic men with a mean age of 23 (standard error = 1.4) years performed two trials at least 1 week apart in a counterbalanced randomized design. In each trial, participants consumed a test meal (1.2 g fat, 1.1 g carbohydrate, 0.2 g protein and 68 kJ x kg(-1) body mass) between 08.00 and 09.00 h following a 12 h fast. The afternoon before one trial, the participants performed an 88 min bout of resistance exercise. Before the other trial, the participants were inactive (control trial). Resistance exercise was performed using free weights and included four sets of 10 repetitions of each of 11 exercises. Sets were performed at 80% of 10-repetition maximum with a 2 min work and rest interval. Venous blood samples were obtained in the fasted state and at intervals for 6 h postprandially. Fasting plasma triacylglycerol (TAG) concentration did not differ significantly between control (1.03 +/- 0.13 mmol x l(-1)) and exercise (0.94 +/- 0.09 mmol x l(-1)) trials (mean +/- standard error). Similarly, the 6 h total area under the plasma TAG concentration versus time curve did not differ significantly between the control (9.84 +/- 1.40 mmol l(-1) x 6 h(-1)) and exercise (9.38 +/- 1.12 mmol x l(-1) x 6 h(-1)) trials. These findings suggest that a single session of resistance exercise does not reduce postprandial lipaemia.     

Evaluation of a networked staff development strategy for departmental tutor trainers: benefits,limitations and future directions

As part of the 1997–1999 Teaching and Learning Enhancement Plan, the University of Queensland mandated that all its academic departments should conduct tutor training. The University's academic development unit, TEDI (the Teaching and Educational Development Institute) designed a network‐based staff development strategy for the development of departmental staff designated as tutor trainers. The strategy was known as the Tutor Training Network (TTN). This paper describes the strategy and reports on an evaluation of the Network programme. The data show that although it was very successful, the network‐based strategy has a limited lifespan. Nonetheless it is an effective strategy for wholesale staff development to support institution‐wide implementations of policy or changes in practice.     

Moving between literacy theory and practice with preservice teachers: Listening to their voices

Abstract

The purpose of this study was to investigate two research questions: What literacy learning did preservice teachers experience through a Penpal Project embedded in an early literacy course? What sense did preservice teachers make of the Penpal Project?—with an overarching focus on bridging literacy theory with practice.

Data were gathered in a university classroom setting, situated in a small Western town, over a period of one school semester. Data methods and sources included videotaped participant observation during weekly penpal letter‐sharing, preservice teachers’ reflection journals, focus group interviews, and preservice teachers’ Penpal Project Summaries.

Patterns emerged from the data and were conceptualized under three broad categories: discourse, discovery and dilemmas. In the discourse category, cultivating relationships and learning through collaboration emerged as themes. Discoveries included meaning‐ and skill‐centered interpretations and professional learning. With regard to dilemmas, preservice teachers reported feelings of inadequacy in decoding their penpals’ letters, in finding topics to pique their penpals’ interests, and in making logical speculations.

Conclusions highlighted the importance of including field experiences in teacher education courses in order for preservice teachers to integrate early literacy theory and practice. A focus on forming relationships, working in collaboration with others, and acknowledging and solving challenges revealed added benefits for the preservice teachers, including a deeper understanding of young students’ early literacy development.     

Continuity of Care,Professional Community,and the Policy Context: Potential Benefits for Infant and Toddler Teachers' Professional Development

Practice or Policy: Continuity of care (COC) has many benefits for young children's development but is not the norm in infant/toddler classrooms. As a consequence, policymakers might not realize how such an approach might also benefit the professional development of infant and toddler teachers, particularly if they come to the field with little formal training. Although the supports and policies available to military child development centers may not be possible to implement at present in much of the civilian sector, this study suggests that their potential benefit for infant/toddler teachers' learning and practice may be worthy of further inquiry. Research Findings: This study shares the results of an exploratory study of the benefits of COC, professional community, and the larger policy context for staff working in a military child development center serving children aged 0 to 2. COC-related professional development also seems to enhance professional community, which along with the policy context is viewed as an essential aspect of improving teacher learning and practice in the K–12 literature.     

Development of an Evaluation Model for an Introductory Module on Social Medicine

Evaluation of educational programmes is an essential component of the teaching-learning process. Therefore, efficient and effective ways of evaluating programmes or their components need to be identified. In this paper a focus group approach to evaluation is compared with a written format in relation to the time, quality and nature of feedback obtained from participants. The focus group required significantly less student and faculty time than the written evaluation approach. The focus group also yielded specific and therefore useful information in terms of module development compared with the written evaluations even though the overall impression of the students' experiences of the module as reflected in the written evaluations were more positive.     

Why Are You Saying That? Increases in Gaze Duration as Responses to Group Member Dissent

The present study investigated students’ eye gaze while reacting to dissenting peers in groups. We measured the duration of gaze toward a confederate who disagreed with either a prevailing idea around which the group was coalescing or the process by which the group was solving a problem. Results indicated that participants gazed at dissenting confederates longer than at confederates in control groups. Qualitative analysis suggested that participants seemed to use eye gaze to understand the confederate, to prompt the confederate to contribute to discussions, to ease tensions, and to process information relative to the group’s task. Results provide an expanded look at how group members respond to dissenters, how conflict operates in some student groups, and how group members may differentiate acceptable and unacceptable disagreement.     

Educational effects of the Tools of the Mind curriculum: A randomized trial

The effectiveness of the Tools of the Mind (Tools) curriculum in improving the education of 3- and 4-year-old children was evaluated by means of a randomized trial. The Tools curriculum, based on the work of Vygotsky, focuses on the development of self-regulation at the same time as teaching literacy and mathematics skills in a way that is socially mediated by peers and teachers and with a focus on play. The control group experienced an established district-created model described as a “balanced literacy curriculum with themes.” Teachers and students were randomly assigned to either treatment or control classrooms. Children (88 Tools and 122 control) were compared on social behavior, language, and literacy growth. The Tools curriculum was found to improve classroom quality and children's executive function as indicated by lower scores on a problem behavior scale. There were indications that Tools also improved children's language development, but these effects were smaller and did not reach conventional levels of statistical significance in multi-level models or after adjustments for multiple comparisons. Our findings indicate that a developmentally appropriate curriculum with a strong emphasis on play can enhance learning and development so as to improve both the social and academic success of young children. Moreover, it is suggested that to the extent child care commonly increases behavior problems this outcome may be reversed through the use of more appropriate curricula that actually enhance self-regulation.     

Effect of acquisition rates on off‐task behavior of kindergarten students while learning sight words

Assessing a student's acquisition rates (ARs) is a reliable way to determine how many new words should be taught in one lesson without reducing retention. Exceeding a student's AR can result in frustration and problem behaviors. The purpose of this study was to examine the effect of AR on the off‐task behavior of kindergarten students while participating in a commonly used sight‐word instruction video. Participants included 39 kindergarten students whose ARs were assessed before showing the sight‐word video. Behavior was measured as on‐ and off‐task using momentary time‐sampling with 10‐s intervals. Results indicated that students' time off task increased after exceeding their ARs, with a noticeable immediate increase. The implications and limitations of these results are discussed.
