A Longitudinal Study of Forms and Functions of Aggressive Behavior in Early Childhood

The purpose of this study was to investigate the distinct forms (i.e., physical and relational) and functions (i.e., proactive and reactive) of aggressive behavior during early childhood ( n  =   101; M age = 45.09 months). Forms, but not functions, of aggressive behavior were stable over time. A number of contributors to aggression were associated with distinct subtypes of aggressive behavior. Females and socially dominant children were more relationally aggressive and older children were less physically aggressive than their peers. Longitudinal analyses indicated that social dominance predicted decreases in physical aggression and peer exclusion predicted increases in relational aggression. Overall, the results provide support for the distinction between subtypes of aggression in early childhood.     

Differences in step characteristics and linear kinematics between rugby players and sprinters during initial sprint acceleration

The initial steps of a sprint are important in team sports, such as rugby, where there is an inherent requirement to maximally accelerate over short distances. Current understanding of sprint acceleration technique is primarily based on data from track and field sprinters, although whether this information is transferable to athletes such as rugby players is unclear, due to differing ecological constraints. Sagittal plane video data were collected (240?Hz) and manually digitised to calculate the kinematics of professional rugby forwards (n?=?15) and backs (n?=?15), and sprinters (n?=?18; 100?m personal best range?=?9.96–11.33?s) during the first three steps of three maximal sprint accelerations. Using a between-group research design, differences between groups were determined using magnitude-based inferences, and within-group relationships between technique variables and initial sprint acceleration performance were established using correlation. Substantial between-group differences were observed in multiple variables. Only one variable, toe-off distance, differed between groups (d?=??0.42 to ?2.62) and also demonstrated meaningful relationships with sprint performance within all three groups (r?=??0.44 to ?0.58), whereby a stance foot position more posterior relative to the centre of mass at toe-off was associated with better sprint performance. While toe-off distance appears to be an important technical feature for sprint acceleration performance in both sprinters and rugby players, caution should be applied to the direct transfer of other kinematic information from sprinters to inform the technical development of acceleration in team sports athletes.     

Stressors, coping, and coping effectiveness: gender, type of sport, and skill differences

The aim of this study was to examine stressors, coping, and coping effectiveness as a function of gender, type of sport, and skill. The sample consisted of 749 undergraduate athletes (455 males, 294 females) aged 18-38 years (mean= 19.8 years). Skill was classified as international/national, county, university, and club standard. Participants completed a stressor and coping concept map (Novak & Gowin, 1984). The results revealed gender, type of sport, and skill differences in relation to stressor frequencies, coping strategy deployment, and coping effectiveness. In contrast to previous research, females used a variety of problem-focused (e.g. planning, communication, technique-orientated coping) strategies more frequently than males. Team sport athletes reported a variety of sport-specific stressors relating to the demands of playing in a team environment. The group of national/international athletes reported using more planning, blocking, and visualization, and also reported that their coping was more effective than that of less-skilled athletes.     

The importance of early phonics improvements for predicting later reading comprehension

The role of phonics instruction in early reading development has been the subject of significant conjecture. Recently, England implemented a phonics screening check to assess the phonetic decoding of 6-year-old students, to ensure that all students master this foundational literacy skill and attain adequate phonemic awareness in the early years of primary schooling. Students who fail this check are obliged to retake the assessment the following year. In this article, we compare the performance of students who initially pass this check (pass) and students who fail the original assessment but pass the retaken assessment (fail–pass), with students who fail both the original and retaken assessments (fail–fail). Using data from the Key Stage 1 assessment of reading and the Progress in International Reading Literacy Study (PIRLS), we examined the reading comprehension performance of these students approximately 1 and 4 years after their first phonics screening. The results suggested that fail–pass students performed substantially better than fail–fail students, even after performance on the initial phonics check was controlled for. While fail–pass students do not appear to entirely catch up with pass students in reading comprehension, their relatively better performance underscores the importance of intervening for those students who are identified as having problems with phonetic decoding to increase their likelihood of success at reading comprehension in later schooling.     

Communication,Communication, Communication! Growth through Laboratory Instructing

This study examined gains undergraduate students made in their communication and collaboration skills when they served as peer teachers, i.e., laboratory instructors (LIs), for a General Psychology laboratory. Self-ratings of communication and collaboration skills were completed before and after teaching the laboratory. When compared to before the teaching experience, the students rated their skills significantly higher in written expression, oral expression, and participation skills. They also rated themselves significantly higher in written comprehension and expression skills than did a comparison group of non-LIs. Results from interviews also revealed beliefs that their communication and collaboration skills had substantially increased.     

Understanding science teaching effectiveness: examining how science-specific and generic instructional practices relate to student achievement in secondary science classrooms

ABSTRACT

In order to create conditions for students’ meaningful and rigorous intellectual engagement in science classrooms, it is critically important to help science teachers learn which strategies and approaches can be used best to develop students’ scientific literacy. Better understanding how science teachers’ instructional practices relate to student achievement can provide teachers with beneficial information about how to best engage their students in meaningful science learning. To address this need, this study examined the instructional practices that 99 secondary biology teachers used in their classrooms and employed regression to determine which instructional practices are predictive of students’ science achievement. Results revealed that the secondary science teachers who had well-managed classroom environments and who provided opportunities for their students to engage in student-directed investigation-related experiences were more likely to have increased student outcomes, as determined by teachers’ value-added measures. These findings suggest that attending to both generic and subject-specific aspects of science teachers’ instructional practice is important for understanding the underlying mechanisms that result in more effective science instruction in secondary classrooms. Implications about the use of these observational measures within teacher evaluation systems are discussed.     

Journal marketing in North America

Preventing alcohol-exposed pregnancy among American-Indian youth

Research has determined that the prevention of alcohol-exposed pregnancies (AEP) must occur preconceptually, either by reducing alcohol intake in women planning pregnancy or at risk for becoming pregnant, or by preventing pregnancy in women drinking at risky levels. One such AEP prevention programme with non-pregnant American-Indian (AI) women is the Oglala Sioux Tribe (OST) Changing High-risk alcohOl use and Increasing Contraception Effectiveness Study (CHOICES) Programme, which shows promise in reducing AEP risk in AI women aged 18 or older. A community needs assessment was conducted with key informant interviews and focus groups with an emphasis on how to expand OST CHOICES. To identify relevant inter-related themes, a content analysis was conducted on qualitative feedback from the focus groups and interviews. Altogether, key informant interviews were completed with 25 health and social service professionals. Eight focus groups were held with 58 AI participants, including adult women of child-bearing age, elder women, and adult men. Several sub-themes regarding the prevention of AEP with youth were identified, expanding the OST CHOICES curriculum into the schools, and the role of family and culture within AEP prevention.
