An investigation of a novel three-dimensional activity monitor to predict free-living energy expenditure

The aim of this study was to assess the capability of the 3dNX accelerometer to predict energy expenditure in two separate, free-living cohorts. Twenty-three adolescents and 14 young adults took a single dose of doubly labelled water and wore a 3dNX activity monitor during waking hours for a 10-day period while carrying out their normal routines. Multiple linear regression with backward elimination was used to establish the strength of the associations between various indices of energy expenditure, physical activity counts, and anthropometric variables. 3dNX output accounted for 27% and 35% of the variance in the total energy expenditure of the adolescent and young adult cohort, respectively. The explained variance increased to 78%, with a standard error of estimate of 7%, when 3dNX output was combined with body composition variables. The 3dNX accelerometer can be used to predict free-living daily energy expenditure with a standard error of estimate of 1.65 MJ in adolescents and 1.52 MJ in young adults. The inclusion of anthropometric variables reduces the error to approximately 1 MJ. Although it remains to cross-validate these models in other populations, early indications suggest that the 3dNX provides a useful method of predicting energy expenditure in free-living individuals.     

Towards an understanding of the learning processes that occur in synchronous online seminars for the professional development of experienced educators

The National College for School Leadership (now the National College) exists to serve the development needs of school leaders in England. The College has begun to use web conferencing in several areas of its work including its professional development programmes, strategic initiatives and support and networking opportunities. Web conferencing tools offer a range of modes of interaction including audio, chat, text, desktop sharing, presentations and video conferencing. It thus has the potential for multi-process learning. The research reported here investigated the ways in which multi-process learning using these tools can be understood. It asked ‘What insights can be gained into the learning processes occurring in synchronous online seminars involving experienced educators? A literature review was carried out to provide background on the current thinking about learning through web conferencing and to explore factors that might be essential for the collective construction of knowledge in this context. Recorded internal and external NCSL web conferences were chosen as case studies; these provided the data for independent qualitative analysis by each of the researchers. From this analysis a model of the learning processes, identified in the data, was developed and related to the current literature. The major findings and model were further reviewed, in the light of their own web-conferencing experiences, by a large number of expert College educators. The resulting ‘model of multi-process learning in web conferencing’ identifies the part played by social, informational, individual internalisation and co-construction stages in multi-process learning.     

Using student-generated questions for student-centred assessment

In small groups, medical students were involved in generating questions to contribute to an online item bank. This study sought to support collaborative question‐writing and enhance students’ metacognitive abilities, in particular, their ability to self‐regulate learning and moderate understanding of subject material. The study focused on supporting students to write questions requiring higher order cognitive processes. End‐of‐year formal examinations comprised 25% student‐generated questions (SGQs), while mid‐year examination items were completely unseen. Data were gathered from repeated administration of a questionnaire and from examination results. No statistically significant changes were identified in self‐rated monitoring of understanding and regulation of learning. The activity of generating questions supported students to work collaboratively in developing questions and answers. The bank of questions was appreciated by students as a source of revision material, even though it was not strongly focused on higher order processes. Based on scores, it would appear that many students chose to memorise the question bank as a ‘high‐yield’ strategy for mark inflation, paradoxically favouring surface rather than deep learning. The study has not identified directly improvements in metacognitive capacity and this is an area for further investigation. Continual refinement of the study method will be undertaken, with an emphasis on education of students in developing questions addressing higher order cognitive processes. Although students may have memorised the questions and answers, there is no evidence that they do not understand the information.     

The visualization of spatial transformations in diagrams of molecular structures

Summaries

English

The investigation sets out to determine in absolute terms the average level of performance of English and Portuguese students in visualizing how diagrams of molecules should be drawn after performing a rotation, reflection or inversion on the molecule itself. A second aim was to determine the factor structure of these tasks. Both aims were investigated using tests comprising samples of items randomly selected from domains of items which operationally defined each task. The results showed that for the students in both countries, the average level of performance on each of these tests was far from satisfactory. The factor structure separated items corresponding to the rotations, reflections and inversions. Within the categories of items corresponding to rotations and reflections, the students from the two different countries give rise to different patterns of loadings for the three different types of rotations and three different types of reflection.     

An Investigation of Factors Relating to Retention of Student–Athletes Participating in NCAA Division II Athletics

Most studies investigating retention of college students have broadly looked at the entire student population. Few attempts have been made to determine if there are specific issues related to the retention of student–athletes. Factors involved in retaining student–athletes were examined by surveying two groups of participants currently enrolled or previously enrolled at a college participating at the National Collegiate Athletic Association (NCAA) Division II level. Student–athletes active in their sport and students no longer actively playing their sport were recruited. The survey consisted of 37 questions using a Likert Scale format as well as two open-ended questions. Eight areas related to retention were examined. Findings indicated that relationships with the head coach, satisfaction with the athletic department, team success, personal reasons, academic concerns, and player development were factors leading to retention or withdrawal from athletic participation. The findings of this study should aid college faculty, administrators, and coaches in their attempts to retain their student–athletes and also be helpful in recruiting practices related to this specific portion of the student body.     

A review and new framework for instructional design practice variation research

This article reviews practice variation in the field of instructional design. First, it compares instructional designer practice as reported or observed in several classic research studies. This analysis is framed by the standards established by the International Board for Training, Performance, and Instruction competencies for planning and analysis, design and development, implementation, and management. Although no certain causal linkages exist, we briefly review some of the reasons posited in the literature to explain instructional design practice variation (lack of time and resources, control in decision making, the designer's perception of a task, underlying philosophical beliefs, and designer expertise). Limitations of the literature base are explored, followed by a proposal for an alternative view of instructional design practice variation and recommendations.     

Discovering Music: Small-Scale,Web-Scale,Facets, and Beyond

In this presentation, two music librarians addressed the issues related to the discovery of library music resources. Rebecca Belford talked about the Music Library Association’s “Music Discovery Requirements” (MLA MDR) document, and how it applies to some contexts. Tracey Snyder then described the incorporation of MLA MDR into the development of a specific discovery interface. The presenters identified some of the challenges characteristic of music resources and ways in which those challenges may be met, reasoning that a tool capable of handling music will be capable of handling most things in a general collection.
