Influence of foot-stretcher height on rowing technique and performance

Strength, technique, and coordination are crucial to rowing performance, but external interventions such as foot-stretcher set-up can fine-tune technique and optimise power output. For the same resultant force, raising the height of foot-stretchers on a rowing ergometer theoretically alters the orientation of the resultant force vector in favour of the horizontal component. This study modified foot-stretcher heights and examined their instantaneous effect on foot forces and rowing technique. Ten male participants rowed at four foot-stretcher heights on an ergometer that measured handle force, stroke length, and vertical and horizontal foot forces. Rowers were instrumented with motion sensors to measure ankle, knee, hip, and lumbar–pelvic kinematics. Key resultant effects of increased foot-stretcher heights included progressive reductions in horizontal foot force, stroke length, and pelvis range of motion. Raising foot-stretcher height did not increase the horizontal component of foot force as previously speculated. The reduced ability to anteriorly rotate the pelvis at the front of the stroke may be a key obstacle in gaining benefits from raised foot-stretcher heights. This study shows that small changes in athlete set-up can influence ergometer rowing technique, and rowers must individually fine-tune their foot-stretcher height to optimise power transfer through the rowing stroke on an ergometer.     

Evaluating prospective elementary teachers' understanding of science and mathematics in a model preservice program

Two cohorts of students preparing to become elementary teachers participated in a model program in science and mathematics. These students were compared to other students taking similar courses on their conceptual understandings of science and mathematics, their investigative proficiencies, and their beliefs about effective methods of teaching these subjects. Instruments included newly developed tests of understanding, existing standardized achievement tests, and instruments devised for the evaluation to elicit conceptions of appropriate ways to teach science and mathematics to elementary children. Results from individual courses indicated that students participating in the model program developed more thorough understandings and more reform-minded beliefs related to teaching science and mathematics. Issues associated with the assessment and evaluation of innovative programs in science and mathematics are discussed, and recommendations for teacher preparation are offered.     

Linking technology,learning, and stories: Implications from research on hypermedia video-cases

Teacher educators have been turning to video-based hypermedia cases as a strategy to confront the challenges of preparing teachers. Even though technology has been shown to have a transformative effect on teaching and learning, innovated uses in classrooms have been the exception rather than the norm. This paper describes how a teacher candidate responded to video and hypermedia cases in ways that assisted her in transforming knowledge and beliefs about literacy instruction. The author describes this transformative process, explores the relationship between narrative ways of knowing and learning from technology, and discusses implications for teacher preparation.     

Improving engagement in an early career academic setting: can existing models guide early career academic support strategies?

ABSTRACT

Early career academics (ECAs) represent the future of the academic workforce, but competition and career uncertainty is resulting in disengagement and burnout. In professions outside academia, increased engagement is associated with perceived organisational support and fair recognition and rewards, as well as opportunities to meet basic psychological needs of autonomy, competence and relatedness. In contrast, decreased engagement is linked with increasing demands on effort and over-commitment to work. The current study used multiple linear regression to test whether comparable relationships were observed in a sample of 151 ECAs in an Australian university. Opportunities to build and demonstrate competence at work, the presence of meaningful relationships and perceived organisational support were independent and statistically significant predictors of engagement. The need for autonomy and fair rewards and recognition appeared to be correlated but not statistically significant predictors of engagement. Contrary to prediction, increasing effort and over-commitment to work did not predict decreases in engagement. These results are discussed in light of implications for programs designed to support the development of ECAs into various career pathways.     

‘Post’ Haste: plodding research and galloping theory

This paper outlines the difficulties in conceptualising and presenting research, in particular doctoral work in education, in the current climate of intellectual theorising. It argues that many researchers experience a phenomenon described in the paper as ‘post‐modernist tension’ when trying to write in an atmosphere of theoretical and methodological uncertainty. The author elaborates the ‘symptoms’ of post‐modernist tension, and makes a critique of some elements of contemporary social theorising. Nevertheless, the author acknowledges the usefulness of contemporary social theory in challenging traditional research, despite its density and inaccessibility to many researchers     

Taking the Guesswork out of Locating Evidence‐Based Mathematics Practices for Diverse Learners

Legislations mandates that educators use evidence‐based practices (EBPs) that are supported by scientifically based research. EBPs have demonstrated a likelihood to work for students with disabilities. EBPs should match targeted needs of the student receiving the instruction, which sometimes requires educators to search for the best intervention to meet specific student needs. This article discusses the impetus for practices supported by evidence, where to find interventions and strategies, and what to do when targeted interventions do not exist. Additionally, this article emphasizes the need to evaluate effectiveness of intervention at the student level.     

COMMON CHARACTERISTICS OF WRITING INTERVENTIONS FOR STUDENTS WITH LEARNING DISABILITIES: A SYNTHESIS OF THE LITERATURE

Twenty‐three single‐subject studies aimed at improving the writing achievement of students identified as having a learning disability were analyzed meta‐analytically. The effect size phi was used to compare the writing strategies. The dependent measures used to assess the efficacy of the interventions were also coded and reviewed. Results suggest intervention studies using the self‐regulated strategy development (SRSD) or a non‐SRSD writing strategy produced high effect sizes, suggesting the overall success of the writing interventions. Findings also indicate the 23 studies used a total of 39 dependent measures, which show the way writing achievement is measured varies greatly. Furthermore, many of the dependent measures were not standardized or technically sound.     

Small-scale curriculum changes for improving pre-service teachers’ preparation for Family-School Partnerships

Abstract

Family-School Partnerships (FSP) are important for students’ academic achievements and social-emotional development. Therefore, pre-service teachers need to learn how to establish this. However, in teacher education programmes this topic is insufficiently addressed partially attributed to already overloaded programmes. This study reports on a small-scale curriculum change, aiming to foster pre-service teachers’ awareness of the importance of FSP, to broaden their concepts and support them in identifying learning goals for the future. An assignment to interview novice-teachers about FSP was followed by a class on this topic. Afterwards, pre-service teachers reported in written reflections that they had become aware of the importance of FSP, emphasising that FSP is more than just communication. However, their focus for further professionalisation remained on improving their communication skills. Though this small-scale curriculum change seems to be a small step forward to a better preparation on FSP, further improvements are necessary to promote a comprehensive view of FSP.
