Teachers’ epistemic cognition in situ: Evidence from classroom assessment

Assessment tasks require the coordination of multiple knowledge-related goals for various audiences, and therefore provide an authentic context to observe teachers’ epistemic cognition in practice. In this instrumental case study, we investigated seven, fifth grade English Language Arts teachers’ epistemic cognition as they evaluated students’ classroom assessments. Our analyses revealed that the components of epistemic cognition identified in the literature emerged in these teachers’ assessment processes. Moreover, we found evidence that teachers’ epistemic cognition was iterative and nuanced, and required shifts in aims and reliable processes. This resulted in teachers forming new kinds of “epistemic matters” and questions beyond those ideas noted in existing models of epistemic cognition. Significance and implications are discussed.     

Teachers’ self-efficacy and intercultural classroom practices in diverse classroom contexts: A cross-national comparison

This cross-national study provides new insights in teacher efficacy in today’s culturally diverse classrooms using survey data of 269 early childhood and primary school teachers in England, Italy, the Netherlands and Poland. Teacher efficacy can be viewed as a two dimensional concept in which both general beliefs are measured alongside (diversity-related) domain-specific beliefs. These beliefs are related to the cultural classroom context and the use of intercultural classroom practices. Our results indicate that policies and professional development targeted at the reciprocal relation between diversity-related efficacy and practices are important when preparing teachers for working in diverse classroom contexts.

Combined individual scrummaging kinetics and muscular power predict competitive team scrum success

Scrummaging is a major component of Rugby Union gameplay. Successful scrummaging is dependent on the coordination of the forward players and the strength of the eight individuals. The study aim was to determine whether individual scrummaging kinetics and other candidate factors associated with scrummaging performance discriminate team scrum performances. Sixteen club-level forwards (stature: 1.80?±?0.1?m; mass: 99.0?±?18.2?kg) were initially divided into two scrummaging packs. A total of 10 various scrum permutations were tested, where players were randomly swapped between the two packs. Winning scrums were determined by two observers on opposite sides of the scrum. Fatigue (100?mm visual analogue scale (VAS)) and scrummaging effort (6–20 rating of perceived exertion (RPE)) were assessed following each scrum contest. Individual scrummaging kinetics were acquired through an instrumented scrum ergometer and muscular power indicated through vertical jump heights. Student’s t-tests were used to differentiate between winning and losing scrum packs. VAS and RPE were assessed using repeated measures ANOVAs. Winning scrum packs had significantly larger combined force magnitudes (p?<?.002), regardless of the player contribution calculations. Additionally, winning packs had less individual movement (p?=?.033) and higher combined vertical jump heights (p?<?.001) but were not significantly heavier (p?=?.759) than losing scrum packs. While perceived VAS and RPE values progressively increased (p?<?.001), no differences in the individual scrum magnitudes were observed between the 1st and 10th scrum (p?=?.418). The results indicated that the combination of individual forces, variation in movement and factors related to scrummaging performance, such as vertical jump height, were associated with team scrummaging success.     

Teen Perceptions of the Promotion of Safer Sexual Practices: A Focus Group Study

Teens' own thoughts on fostering safe sexual practice are important perspectives in promoting adolescent sexual health yet are relatively absent in the literature. This focus group study explored teens' perceptions about the supports and challenges that exist as teens strive to engage in healthy sexual practices. Seventy-five teens participated in 11 focus groups using a semi-structured interview guide. School-based health centers provided the setting and facilitated sample recruitment. Focus groups were audiorecorded and transcribed verbatim. Data were analyzed using the focus group guide as a template and typologies, or clusters of concepts, were extracted to establish teen perceptions of the factors that support and challenge their ability to engage in safe sexual practices. The socio-ecological model provided the framework to identify these factors within the individual, family/parent, relational (peer/partner), community, or societal spheres of influence. Results discussed the importance of parents, the value of confidentiality, respect for teen decision-making, relationships skills, developmental aspects of the adolescent years, and social interpretations of gender. These findings revealed important considerations as adults develop policies, messages, and programs designed to promote safe sexual behavior in teens.

How social relationships influence academic health in the ‘enterprise university’: an insight into productivity of knowledge workers

The comparatively poor mental health status of academics at Australian universities compared with the general Australian workforce poses a public health challenge. Productivity of knowledge workers is a key issue for the new economy. Using the case of one university, I interviewed employees stratified by level of employment and showed that their mental health is adversely affected by social relationships that result from historically‐based bargains. These rely on divergent and sometimes adversarial value systems of employers and employees and a preference for particular institutional policies and practices based on contemporary cultural trends of individualism and economic rationalism that affect social support and social networks in a detrimental way. To redress this burden of mental illness, it is imperative that employer‐employee discourse is changed to incorporate the social reality of the work context. This study offers insights into productivity of knowledge workers generally in service industries of education, information and communication.
