Development and Validation of an Instrument for Assessing Distance Education Learning Environments in Higher Education: The Distance Education Learning Environments Survey (DELES)

The purpose of this study was to develop and validate a new learning environments instrument designed to aid investigators and practitioners in measuring and researching the psychosocial learning environment in post-secondary distance education. Using a three-stage approach, the Distance Education Learning Environments Survey (DELES) was developed, field-tested with 680 distance education students, and then validated. The DELES has 34 items allocated to six scales: (1) Instructor Support; (2) Student Interaction and Collaboration; (3) Personal Relevance; (4) Authentic Learning; (5) Active Learning; and (6) Student Autonomy. An additional scale of Enjoyment was included in this study to explore associations between the psychosocial learning environment and student affective traits. Each learning environment item had a factor loading of at least 0.50 with its own scale, and less than 0.50 with all other scales. The alpha reliability coefficient for each scale ranged from 0.75 to 0.94. Simple correlations between Enjoyment and the DELES scales ranged from 0.12 to 0.31, with the scale of Personal Relevance having the strongest correlation with Enjoyment when all other scales were mutually controlled. The DELES, an online instrument that can be utilized by students at any location, eliminates data transfer errors and does not allow for non-responses, adding to the overall validity of the instrument. The development of DELES relied extensively on literature pertaining to high-quality distance education and expert content validation techniques. It treats distance learning as having a distinct social-psychological climate unlike those found in other post-secondary classroom environments.     

Spine biomechanics associated with the shortened,modern one-plane golf swing

The purpose of this study was to compare kinetic, kinematic, and performance variables associated with full and shortened modern backswings in a skilled group of modern swing (one-plane) golfers. Shortening the modern golf backswing is proposed to reduce vertebral spine stress, but supporting evidence is lacking and performance implications are unknown. Thirteen male golfers performed ten swings of each swing type using their own 7-iron club. Biomechanical-dependent variables included the X-Factor kinematic data and spine kinetics. Performance-related dependent variables included club head velocity (CHV), shot distance, and accuracy (distance from the target line). Data were analysed with repeated measures ANOVA with an a priori alpha of 0.05 (SPSS 22.0, IBM, Armonk, NY, USA). We found significant reductions for the X-Factor (p < 0.05) between the full and shortened swings. The shortened swing condition ameliorated vertebral compression force from 7.6 ± 1.4 to 7.0 ± 1.7 N (normalised to body weight, p = 0.01) and significantly reduced CHV (p < 0.05) by ~2 m/s with concomitant shot distance diminution by ~10 m (p < 0.05). Further research is necessary to examine the applicability of a shortened swing for golfers with low back pain.     

On Explaining Change in School Subjects

Drawing on a recent empirical study of curriculum change in English secondary school mathematics, an attempt is made to develop a model for analysing how and why changes occur in the legitimacy of particular definitions of secondary school mathematics and science subjects. Specifically, the author seeks to articulate various insights from the work of Kuhn, Bucher & Strauss, Archer and Bhaskar in a manner which allows structural and interactional perspectives to be simultaneously brought to bear on the phenomenon of subject redefinition. Material from the empirical study is used, where appropriate, both to illustrate and support the arguments presented in favour of the model.     

Schools and the transformation of a metropolis

This paper describes the urban decay and deconcentration process in the St. Louis metropolitan area and its relationship to the changes that have occurred in the public school systems in the area. Evidence is offered to suggest that schools are as much the victim of urban decay as they are a cause of it. Because of the linkages between these two processes, it is concluded that urban decay cannot be reversed without reviving schools and that the problems exhibited in many school systems cannot be dealt with unless the urban decay process is slowed or reversed.     

中国高校外语教学刍议

长期以来，中国的外语教学都是把听、说、读、写等基本技能分隔成相对独立的板块来实施的。因此，就有了口语、听力、写作、泛读和精读等诸多课程。在外语教学中最将将采用集各种技能为一体的整体教学思路和方法。其使用和完善将极大地促进中国的外语教学。     

Can any good come out of researching in science education and being a science teacher at the same time?

Recent experience has demonstrated that for an aged researcher, teaching secondary school science at a selective high school while committed to carrying out research in science education is riddled with difficulties. With respect to the research, problems ranged from there being too much time required to establish one's credentials as a teacher, to too much research being too easily suggested and undertaken. With respect to the teaching, among other things, it was too time-consuming, there were too many other duties to perform and other teachers became too involved in one's own interests. To make matters worse, there were too many students, they were too varied, too interesting and the relationship with them became too rewarding. A thoroughly disturbing state of affairs. Specialisations: chemical education, history and philosophy of science, laboratory work, student conceptualisations.     

Psychological health of doctoral candidates,study-related challenges and perceived performance

Psychological distress is prevalent in doctoral degree training and affects students' completion time. It is crucial to monitor the amount of distress experienced and understand the causes for it to inform the type of support most needed. This mixed method study explored challenges related to candidature, self-reported progress and measures of perceived and actual psychological distress with a convenience sample of 81 doctoral candidates in an Australian university. Using validated survey instruments, participants reported higher levels of depression, anxiety and stress than age-matched general population normative data. Additionally, those who self-reported being behind or exceeding their study schedule had significantly higher scores for depression, anxiety and stress than those who reported they were meeting schedule. Conversely, stage of candidature did not affect any of these attribute scores. The responses to open-ended questions about challenges associated with doctoral study were coded and explored with an existing typology. The most frequent challenge reported in doctoral study is related to the development of generic skills, followed by management of self, including motivation. Given that not all challenges could be included in the existing typology, we recommend expansion to the typology.
