Random and blocked practice of movement sequences: differential effects on response structure and movement speed

Three similar six-element key press sequences were practiced under blocked or random practice schedules with acquisition conducted on one day and retention and transfer on the next day. The task required participants to type, as quickly as possible, one of three 6-element sequences as observed on a computer monitor. In blocked practice, participants completed all practice in one repeated sequence before the next repeated sequence was introduced. In random acquisition practice, the three repeated sequences were randomly presented to the participants. The data suggest that random practice results in participants adopting a uniform response structure, while blocked practice allows participants to exploit unique sequential aspects of the individual tasks. This finding suggests that random practice may not be as effective as blocked practice when one of the tasks being practiced together can be optimized through the development of a unique response structure.     

‘Speaking’ deficit into (or out of) existence: how language constrains classroom teachers’ knowledge about instructing diverse learners

This article explores the talk among novice teachers who participated in an inquiry project designed to rethink the instruction for their struggling students by drawing upon competence rather than deficiencies. A critical discourse analysis (CDA) based on theories of systemic functional linguistics and CDA provided tools to explore how their use of language afforded or constrained their efforts to better serve diverse learners in their urban elementary classrooms. The analysis indicates the power of normative and deficit discourses that continue to predominate within educational culture. It reflects on this analysis and discusses potential benefits of centralising language awareness and a social/critical lens to ongoing professional development.     

Perceptions of the usefulness of the IEP by teachers of learning disabled and emotionally disturbed children

The present study used questionnaires to examine the perceptions of the usefulness of the Individualized Education Program (IEP) by teachers of emotionally disturbed and learning disabled children. Teachers surveyed indicated that the IEP does have some general utility for them and their students. However, the majority of respondents also indicated that the IEP does not usually assist them in planning day-to-day instruction. Additionally, they do not refer to the actual IEP document very often, nor is it particularly accessible to them. It was concluded that the IEP will not qualitatively affect the education of handicapped students unless it guides the delivery of services on a daily basis.     

Towards a more inclusive approach to intervention research: the case of research in learning disabilities

Intervention research in special education tends to rely on comparisons of mean differences to determine instructional strategies that ‘work’ for students with disabilities. This reliance on mean differences obscures individual variation that is always present in educational research. This paper examines the degree to which individual variation is acknowledged in reports of intervention research published in four leading learning disabilities journals over a five-year period. It was found that, although there was considerable variance present in intervention studies published in these journals, this variability was often unacknowledged. This paper concludes with suggestions for how researchers might acknowledge variance in their research.     

The Timing of Prenatal Exposure to Maternal Cortisol and Psychosocial Stress Is Associated With Human Infant Cognitive Development

The consequences of prenatal maternal stress for development were examined in 125 full-term infants at 3, 6, and 12 months of age. Maternal cortisol and psychological state were evaluated 5 times during pregnancy. Exposure to elevated concentrations of cortisol early in gestation was associated with a slower rate of development over the 1st year and lower mental development scores at 12 months. Elevated levels of maternal cortisol late in gestation, however, were associated with accelerated cognitive development and higher scores at 12 months. Elevated levels of maternal pregnancy-specific anxiety early in pregnancy were independently associated with lower 12-month mental development scores. These data suggest that maternal cortisol and pregnancy-specific anxiety have programming influences on the developing fetus.     

The impact of short-term adventure-based outdoor programs on college students’ stress reduction

This study examines the effect of short-term adventure-based outdoor programs (AOP) on reducing college students’ stress levels. The effects of sex and different outdoor adventure activities in stress reduction are also evaluated. Thirty-three college students participated in selected short-term backpacking, canoeing, and kayaking programs. Student's salivary samples were collected to evaluate physiological stress response (as measured by levels of cortisol) and their psychological stress levels were collected through a modified 12-item questionnaire. Stress responses were measured at three different time points, including the second weekly meeting in the classroom, before the field trip, and at the conclusion of the field trip. Findings suggest that short-term AOP affords opportunities for college students to be away from daily challenges, and in turn reduce college students’ psychological stress levels and provide a temporary relief of physiological stress levels. No significant differences in college students’ stress levels were found between sex and different outdoor adventure activities.
