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.

Learning to use the Internet as a study tool: a review of available resources and exploration of students' priorities

BACKGROUND: The Internet is a valuable information tool, but users often struggle to locate good quality information from within the vast amount of information available. OBJECTIVE: The aim of the study was to identify the online information resources available to assist students develop Internet searching skills, and to explore the students' priorities in online guides. METHODS: A qualitative approach was adopted with two phases. The first was a structured search of available online study skills resources. The second comprised 10 group interviews with a total of 60 students at all stages of five undergraduate health and social care related courses at a UK university. RESULTS: The study found that there were good online guides available, but that, perversely, the better guides tended to require the best searching skills to locate them. A few students were enthusiastic about using online support, however the majority felt that if they had the skills to locate such resources they wouldn't use a study guide to improve these skills, and if they did not have the skills they would not think of using an online guide to develop them. CONCLUSIONS: Students wanted assistance when they had problems or questions, rather than sites that offered structured learning experiences. Personal support rather than virtual support was also considered to be most important to the students in this study.     

From special to inclusive education in Macau (SAR)

The education for learners with special education needs (SEN) in Macau (SAR), China, has gradually transitioned over the past 30 years from a completely segregated approach to a more inclusive one. Following a review of the development of special education and the transition towards inclusion in Macau, consideration is given to the enactment of inclusive education in mainstream schools. Interviews with the leaders in a primary and secondary mainstream government school in Macau outline the ways in which learners with SEN are included in mainstream schools. The discussion focuses on a range of issues regarding the inclusion movement in Macau, including management, schooling and the inclusive model that is applied.     

New academics’ perceptions of the language of teaching and learning: identifying and overcoming linguistic barriers

Seventy‐seven new academics – 59 at a large, public university in the UK and 18 at a medium‐sized, private comprehensive university in the USA – were asked to read an extract of an article on the scholarship of teaching and learning (SoTL) and mark the text according to categories of difficulty or dislike. Analysis of the data revealed six main linguistic barriers in the text: specialist vocabulary, passive constructions, pronouns, figurative language, derivations and poor editorial standards. These barriers were similar at both institutions, suggesting they apply across different contexts. Contrary to expectations, no conclusive disciplinary‐based distinctions were detected. Implications for both readers and writers are explored and proposals are made for developing a literary style in SoTL literature that is simultaneously accessible and credible.

Soixante‐dix‐sept nouveaux enseignants – cinquante‐neuf provenant d’une université publique britannique de grande taille et dix‐huit provenant d’une université privée américaine de taille moyenne – ont lu l’extrait d’un article portant sur le scholarship of teaching and learning (SoTL) et ont identifié les parties qu’ils jugeaient difficiles ou qu’ils n’appréciaient pas. Une analyse des données révèle la présence de six barrières linguistiques principales dans le texte: le vocabulaire spécialisé, les constructions passives, les pronoms, le langage figuratif, les dérivations et des standards de rédaction de piètre qualité. Ces barrières étaient similaires dans le cas des deux institutions, ce qui suggère qu’elles sont applicables dans des contextes différents. Contrairement aux attentes, aucune distinction reposant sur les disciplines permettant de tirer des conclusions n’a pu être détectée. Les implications pour les lecteurs et les rédacteurs sont explorées et des propositions visant à développer un style littéraire pour la documentation portant sur le SoTL qui soit à la fois accessible et crédible sont formulées.     

Sustaining technological innovation: The example of videoconferencing in English Schools

The main factors associated with technology integration have been the subject of research for over a decade. However, the conditions which sustain technological developments have been less frequently investigated. This paper explores this issue in the context of the use of videoconferencing in schools in England. The research took a multiple case-study approach by returning to schools with a reputation for demonstrating innovative policy and practice in videoconferencing, which were the subject of an earlier investigation. Analysis of developments in the interim five-year period led to the construction of a five-level typology of change. Further analysis identified critical dimensions associated with the sustainability of videoconferencing. These included technical and structural factors, as well as policy frameworks and personnel status. The perceived usefulness and relevance of videoconferencing as a learning technology emerges as a central determinant of sustainability, with the conclusion that for policymakers and schools, videoconferencing has become an ‘orphan’ technology.     

Inclusion in Malaysian integrated preschools

Inclusive education has been introduced through a number of policy developments in Malaysia over the last 10 years but there is little research investigating the extent and nature of inclusive education for preschoolers with special educational needs (SEN). This study surveyed both regular and special education teachers in Malaysian integrated preschools asking them about the level and nature of inclusion taking place in their preschools and their perceptions and beliefs about inclusion. There was little evidence of practices of inclusion taking place. Both regular and special educators agreed that SEN should be educated alongside their peers in a school but were unlikely to agree that the SEN students should be in the same classroom. Factors identified as influencing inclusion included school culture, skills and competency, guidance and information, workload and students' disabilities. More guidelines and support are required for successful inclusion in Malaysian integrated preschools.     

Analysing the Role of the Subject Head of Department in Secondary Schools in England and Wales: Towards a theoretical framework

This paper argues that contingency theory offers a useful basis on which to consider the work of subject heads of department (HoDs) in secondary schools, particularly if they are pro-active in attempting to influence the quality of teaching and learning in their curriculum area. We have developed a provisional model which may shed more light on how HoDs actually work with other departmental staff.     

Primary school students' metacognitive beliefs about religious education

So far scholars have researched beliefs about knowledge, knowing, and learning mainly in the areas of science and mathematics and among secondary school students. In this article, we explore primary school students' metacognitive beliefs about religious education. The article reports on a study involving 656 fifth- and sixth-grade students. We investigated their metacognitive beliefs, how these beliefs interrelate, and which students agree with which beliefs. In the minds of young students 7 categories are discernible: realistic learning, the transformative power of religion, social learning, intrinsic task value motivation, learning satisfaction motivation, the teacher's empathic orientation to learning, and the teacher's respect for students' contributions. These categories and their interrelationships open up new perspectives for the construction of a metacognitive beliefs system and for an interconnected network of beliefs across domains. We also outline implications for religious education in schools.     

Teacher views on the effects of the change from coursework to controlled assessment in GCSEs

When General Certificates of Secondary Education (GCSEs) were introduced in the late 1980s, coursework was included as a requirement in many subjects. Coursework was intended to help best represent students' attainments, but concerns about various issues (e.g., tasks becoming formulaic, authenticity of student work, workload) led to a review and ultimately to its replacement with “controlled assessments”. This research investigated the effects of this change. A questionnaire was completed by 346 teachers across 6 subjects. Most teachers felt the risks of plagiarism are similar or have reduced. Two thirds of teachers reported that the introduction of controlled assessment has affected the way they teach, and around 60% feel it has affected the nature of the knowledge and skills learnt by students. There are reportedly practical challenges relating to timetabling, student absence, and increased administration. However, over 70% of teachers consider it “important” or “very important” to have some form of internal assessment in their subject.
