Teacher expectations and student literacy engagement and achievement

Notwithstanding the complex and dynamic nature of teaching and learning in schools, over four decades of research findings have consistently revealed a correlation between teacher expectations and student achievement. Focusing on teacher expectations for the narrative structures created by young children, this article features a discussion of data gathered during a multifaceted study with 7‐ and 8‐year‐old students. The overall purpose of the case study research was to explore the development of student understanding of elements of visual art and design and diverse narrative structures in picturebooks. For the culminating activity of the research, the students had opportunities to apply and transform their knowledge of the instructional foci when they composed their own multimodal print texts. Analysis of the students' narrative structures revealed the multiple forms of metalepsis, the purposeful breaking of storyworld/narrative boundaries, evident in their writing and artwork. In addition to a discussion about the socially situated nature of the children's multimodal text‐making, the article includes a consideration of the importance of teacher expectations with respect to student literacy engagement and achievement.     

Do You Want to Know What I Learned? Using Informational Trade Books as Models to Teach Text Structure

Informational text is an important resource for classroom teachers that places unique comprehension demands on young students. Research on teaching expository text structure to young children shows that explicit instruction improves student comprehension. This practical article addresses how to use “well-structured” expository trade book titles to teach text structure. A lesson plan template and an extended example of an explicit lesson on order/sequence are provided.     

Aerobic exercise did not have compensatory effects on physical activity levels in type 2 diabetes patients

Although exercise promotes beneficial effects in diabetic patients, some studies have questioned the degree of their importance in terms of the increase in total energy expenditure. In these studies, the decrease of physical activity levels (PAL) was referred as “compensatory effect of exercise”. However, our aim was to investigate whether aerobic exercise has compensatory effects on PAL in type 2 diabetes patients. Eight volunteers (51.1 ± 8.2 years) were enrolled in a supervised exercise programme for 8 weeks (3 d · wk^?1, 50–60% of VO₂ peak for 30–60 min). PAL was measured using tri-axial accelerometers in the 1st, 8th and 12th weeks. Biochemical tests, cardiorespiratory fitness, anthropometric assessment and body composition were measured in the 2nd and 11th weeks. Statistical analysis was performed using non-parametric tests (Friedman and Wilcoxon, P < 0.05). We found no significant differences in PAL between intervention periods, and participants spent the majority of their awake time in sedentary activities. However, the exercise programme generated a significant 14.8% increase in VO₂ peak and a 15% reduction in fructosamine. The exercise programme had no compensatory effects on PAL in type 2 diabetes patients, but improved their cardiorespiratory fitness and glycaemic control.
