Comparison of 2D video and electrogoniometry measurements of knee flexion angle during a countermovement jump and landing task

Quantifying countermovement jump (CMJ) and landing knee flexion angle is important for performance and injury risk assessment. The purpose of the study was to compare electrogoniometer (El-Gon)- and video-derived CMJ and landing knee flexion angle. Twenty-two adults performed three CMJs while knee flexion angle was simultaneously assessed using an El-Gon and video. The average systematic offset (RMSE) of the El-Gon-derived knee flexion angle throughout the entire movement was 7.03°?±?2.69°. Excellent reliability was demonstrated by the El-Gon (ICCavg?=?0.92). Countermovement knee flexion angle, maximum landing knee flexion angle and flexion angle at maximum vertical ground reaction force were 12.0°, 10.9°, and 5.7° higher, respectively, when assessed using El-Gon (p?<?0.001), compared to video. Errors between instruments are likely due to El-Gon crosstalk, misalignment and/or axis determination. The El-Gon is a cost-effective and time-efficient alternative to video analysis for the assessment of knee flexion angle if the error is accounted for and the sensor is precisely attached.     

Response to intervention as a vehicle for distinguishing between children with and without reading disabilities: Evidence for the role of kindergarten and first-grade interventions

Children at risk for early reading difficulties were identified on entry into kindergarten, and half of these children received small-group intervention two to three times a week during their kindergarten year. The other half received whatever remedial assistance was offered by their home schools. These children were again assessed at the beginning of first grade, and those who continued to have difficulties in reading received either one-to-one daily tutoring offered by project teachers from the beginning to the end of first grade or whatever remedial assistance was offered by their home schools over the same time period. All target children were periodically assessed through the end of third grade. Results suggest that either kindergarten intervention alone or kindergarten intervention combined with first-grade intervention are both useful vehicles for preventing early and long-term reading difficulties in most at-risk children.     

Interaction between the teacher and the congenitally deafblind child

Empirical data on the development of interaction, communication, and language in deafblind children is very rare. To fill this gap, a case study was conducted in which the interaction between a teacher and a deafblind boy age 3 years 4 months was analyzed. Sequential analysis of their interaction confirmed some general clinical impressions about interaction with deafblind children, and provided the basis for suggestions on how the interaction pattern might be changed.     

Meeting the highly qualified teachers challenge

The moulding of the future of a nation depends on the teachers and the education they provide in schools. Research evidence from the US. National Assessment of Educational Progress (NAEP) confirms this to be the case. Quantitative analysis of data indicates that measures associated with pre-service teacher preparation are by far the strongest correlates of student achievement (Darling-Hammond 2000). The research report of Wilson, Floden, and Ferrini-Mundy (2001) also suggests a strong relationship between teacher preparation and teacher effectiveness. Other research studies similarly indicate that differences in teacher quality are the most crucial for student achievement when compared with variables such as class size, streaming, or the amount of homework (Anderson & Helms 2001; Mendro 1998; Powell & Anderson 2002; Rivkin, Hanushek & Kain 2001; Saunders & Horn 1994; Strong & Tucker 2000) as possible contributory factors. In the pursuit of improved student achievement, we therefore need to examine seriously the role of teacher variables, ranging from teacher qualifications and their subject matter knowledge, to what motivates them to take up teaching as a career and as a consequence, how they teach in classrooms.     

Using autobiographical queer life narratives of teachers to connect personal,political and pedagogical spaces

Autobiographical queer life narratives are communicative spaces where queer teachers take up personal issues of being, becoming, and belonging in contextual and relational analyses of their situated experiences. In this work w/e consider the challenges and risks involved in this research, which, when shared and probed in classroom spaces, is a dangerous exposition of the queer self. With these challenges and risks in mind, w/e examine how our narratives provide fugitive knowledge to inform a pedagogy of ‘resist-stance’ that recognizes, respects, and engages queer identity, difference, history and culture. W/e provide examples of this pedagogy, discussing teaching strategies currently being used to connect the personal, the political and the pedagogical in classroom spaces. W/e also speak of the difficulties of living out this pedagogy as transformative teaching to transgress queer erasure in hetero-normative educational practice.     

An Air of Sharing. A Format of Open Interviewing in a Joint Nordic Project

The five Nordic countries and their respective quality assurance agencies ¹ 1. EVA, FINHEEC, NOKUT, HSV, and the Ministry of Education, Science and Culture of Iceland. have convened annually for over a decade to exchange experiences and discuss issues concerning quality assurance in higher education. In recent years this has resulted in a regional network for the quality assurance agencies (NOQA). During this period, methodological issues have increasingly been emphasised within the network’s activities, and the current article presents and discusses a new format of open interviewing in a setting where the quality assurance work of four higher education institutions were analysed. The openness of the process was the key in providing an opportunity for the higher education institutions to learn from each other.
