The effect of limb dominance on lower limb functional performance – a systematic review

Lower limb dominance (or lateral preference) could potentially effect functional performance. Clinicians are often asked to make judgements as to when a patient has sufficiently “recovered” from an injury, typically using strength and dynamic performance outcome measures. The primary purpose of this study was to systematically review the literature in relation to limb dominance within active adult populations and discuss some limitations to current methods and relate this to current clinical practice. A search of MEDLINE and CINAHL and EMBASE databases and reference lists of those articles identified was performed. Eleven articles were selected for meta-analysis. There was no statistical effect of limb dominance for any of the functional tests: isokinetic quadriceps and hamstring tests, hamstring:quadriceps ratios, single-leg hop for distance, single-leg vertical jump and vertical ground reaction force following a single-leg vertical jump. Pooled symmetry values varied from 94.6% to 99.6% across the tests, above the clinically accepted benchmark of 90% used in clinical practice. Although the results of this study must be used with discretion, asymmetries in the tasks described in this analysis should be viewed as undesirable and remedied accordingly. Further research is needed to quantify asymmetries, particularly in relation to sport-specific contexts.     

Power Dynamics and Questioning in Elementary Science Classrooms

We describe the dynamic discourse interactions between a teacher and her students in a third-grade science classroom. We focused on how the teacher and students initiate, prompt, respond, and provide feedback; use questioning and power strategies; and how questions are associated with power dynamics. We relate the consequences of teacher use of power to the engagement of student with subject matter. Two classroom sessions were observed and teacher?Cstudent interactions audio recorded. Data were transcribed and a method was developed for analyzing teacher-student interactions, power dynamics, and types of questions asked. Results revealed that teacher talk was twice as frequent as students?? talk; questions were primarily closed-ended and task-oriented; and students asked few questions. The teacher exercised power by keeping activities organized and conventional, and utilizing subject matter. The developed methods showed us the complexity of question and power dynamics in classroom discourse and have implications for professional development and research.     

Building an online community to support the professional development of casual teachers

Abstract

With the burgeoning casualisation of the higher education workforce, the precarious nature of casual teaching has become increasingly well documented. Universities are recognising that enhancing quality learning and teaching must include attention to the provision of services, support, and professional development for teachers employed on a sessional or casual basis. This paper presents a study investigating an online course for supporting and connecting dispersed and diverse casual teachers at an Australian university. The study explores the role of community and the impact of professional development for casual teachers across discipline boundaries in an institution-wide online course.     

Induction of newly qualified teachers in New Zealand

In this research, commissioned by the New Zealand Teachers Council, the quality of induction of provisionally registered teachers (PRT) (newly qualified) was examined utilising qualitative ‘success case studies’ within early childhood, primary, secondary, and indigenous Māori medium settings. The establishment of criteria for effective induction (from the literature and previous research) guided the identification of 20 ‘success’ sites across the sectors. In-depth data collection of each case was conducted via focus groups, one-to-one interviews and documentary analysis. The findings of the research highlighted exemplary induction practices across the sectors, with the most important associated with PRTs having access to a community, or ‘family’, of support during their induction. An interesting finding, which contrasted with previous research, was that PRTs in the secondary sector had levels of satisfaction with their role that were as high as those in other sectors. The key limitation to effectiveness was linked to lack of time for discussions and observations of the PRT's practice.     

‘Philanthropizing’ consent: how a private foundation pushed through national learning standards in Brazil

ABSTRACT

This article explores how the Base Nacional Comum Curricular (National Learning Standards), entered the policy debate in Brazil and became the most important reform initiative of the Ministry of Education between 2015 and 2017. We argue that this accelerated policy process was contingent upon the practice of philanthropizing consent: foundations’ use of material resources, knowledge production, media power, and informal and formal networks to garner the consent of multiple social and institutional actors to support a public policy. In other words, these foundations do not impose policies on governments; rather, they ‘render technical’ high-stakes political debates on pressing issues of educational equity and then influence state officials’ consensus about which policies to adopt. We argue that this philanthropic influence is not simply a neoliberal, profit-maximizing scheme; rather, it is an attempt by foundation and corporate leaders to garner power and influence on different scales, and re-make public education in their own image. Although this educational policy game is in many ways participatory and widely accepted, foundations are only able to play this role due to their tremendous economic power, a direct product of the unequal global political economy, and the systematic defunding of the public sphere.     

Using Sociocultural Theory to Understand the Relationship between Teacher Change and a Science-based Professional Education Program

This paper focuses on a model of teacher change based on a study of a science discipline-based professional education program and on an understanding of teacher change in terms of an agency| structure dialectic. Professional education programs should expand teachers' capacity to act in a range of fields. Conducted over one year, this study used socio-cultural theory to examine the role of cultural schema and resources in the enactment of new pedagogical structures by two teachers who demonstrated widely variable responses to their experience of a professional chemistry education program. Hermeneutic and phenomenological methods of study supported the examination of teacher actions and narratives as sources of data. The analyses of these data sources resulted in greater understanding of the relationship between schema, resources and structure and the relationship between structure and teacher agency. Structures are dynamic and if a teacher uses a resource such as an inquiry-based instruction protocol without the attendant cultural schema such as the value of questioning then the structure that is implemented will be different from that the teacher experienced in the professional education program. This understanding supported an explanation of teacher change in terms of teacher agency that constituted our learning from the study and resulted in changes to aspects of the professional education program.
