The purposes of this study are to gain more insight into students’ actual preferences and perceptions of assessment, into the effects of these on their performances when different assessment formats are used, and into the different cognitive process levels assessed. Data were obtained from two sources. The first was the scores on the assessment of learning outcomes, consisting of open ended and multiple choice questions measuring the students’ abilities to recall information, to understand concepts and principles, and to apply knowledge in new situations. The second was the adapted Assessment Preferences Inventory (API) which measured students’ preferences as a pre-test and perceptions as a post-test. Results show that, when participating in a New Learning Environment (NLE), students prefer traditional written assessment and questions which are as closed as possible, assessing a mix of cognitive processes. Some relationships, but not all the expected ones, were found between students’ preferences and their assessment scores. No relationships were found between students’ perceptions of assessment and their assessment scores. Additionally, only forty percent of the students had perceptions of the levels of the cognitive processes assessed that matched those measured by the assessments. Several explanations are discussed.  相似文献   

Triadic Supervision and its Impact on the Role of the Supervisor: A Qualitative Examination of Supervisors' Perspectives     

Serge Hein  Gerard Lawson 《Counselor Education & Supervision》2008,48(1):16-31

Although triadic supervision has been the subject of little empirical research, perspectives of supervisors in this form of supervision have received even less attention. This qualitative study examined 6 doctoral student supervisors' experiences of triadic supervision and the demands it placed on them in their role as supervisors. Data collection involved use of in‐depth, open‐ended interviews, and a whole‐text analysis resulted in 2 major categories. These categories address various ways in which triadic supervision increases or decreases the demands placed on the supervisor. Implications of the findings for supervisory practices and future research are also addressed.  相似文献   

Separation by dielectrophoresis of dormant and nondormant bacterial cells of Mycobacterium smegmatis

The dielectrophoretic behavior of active, dead, and dormant Mycobacterium smegmatis bacterial cells was studied. It was found that the 72-h-old dormant cells had a much higher effective particle conductivity (812±10 μS cm⁻¹), almost double that of active cells (560±20 μS cm⁻¹), while that of dead (autoclaved) M. smegmatis cells was the highest (950±15 μS cm⁻¹) overall. It was also found that at 80 kHz, 900 μS cm⁻¹ dead cells were attracted at the edges of interdigitated castellated electrodes by positive dielectrophoresis, but dormant cells were not. Similarly, at 120 kHz, 2 μS cm⁻¹ active cells were attracted and dormant cells were not. Using these findings a dielectrophoresis-based microfluidic separation system was developed in which dead and active cells were collected from a given cell suspension, while dormant cells were eluted.  相似文献   

Is sports science answering the call for interdisciplinary research? A systematic review     

Ben Piggott  Sean Müller  Paola Chivers  Carmen Papaluca  Gerard Hoyne 《European Journal of Sport Science》2019,19(3):267-286

Sports science research is traditionally monodisciplinary despite calls for an interdisciplinary focus. The primary purpose of this systematic review was to identify studies on talent identification, talent selection and competition performance to determine whether interdisciplinary research is being conducted. Thirty-six studies met the selection criteria. These studies were critiqued relative to sport, skill level, sport science sub-disciplines included, and whether the research was multidisciplinary or interdisciplinary. The secondary purpose of the review was to critique the level of analysis and level of representative task design in performance tests used in the studies. Twenty-five studies were categorised as interdisciplinary, with 11 categorised as multidisciplinary. Thirteen sports were represented with soccer the most frequent followed by field hockey, Australian Rules football, handball and rugby league. Thirty-two studies completed their analysis at a group level and four at an individual level. A total of 337 performance tests were rated for representative task design with 64 categorised as low, 123 as medium and 150 as high. The results pertaining to interdisciplinary studies and individual analyses are discussed in relation to constraints theory, which predicts that interacting variables can explain sport performance. Sports science research is beginning to fulfil the call for interdisciplinary research. Future research, however, needs to consider individual analyses and representative task design of tests to progress sports science knowledge.  相似文献
