The short-term memory for sounds of the bottlenosed dolphin was tested using symbolic, identity, and probe forms of the delayed matching-to-sample (DMS) task. The forms differed in the number (one or two) or nature (symbolic or identity matches of sample sounds) of postdelay test stimuli available as memory retrieval cues. Although symbolic DMS was difficult to learn, the final performance level was approximately equal to that for identity or probe DMS. On all tasks, the dolphin’s responses were above 80% correct through to delays of 90 sec and, in some cases, through to delays of 180 and 240 sec, the “limits” being governed mainly by the dolphin’s reluctance to continue being tested at long delays. Encoding of sample stimuli into their learned symbolic representation was hypothesized to have reduced symbolic DMS to a recognition memory task, resulting in the observed equivalence of performance with the other two recognition memory tasks. The probe DMS results, unlike those for identity or symbolic DMS, showed no significant proactive interference effects from samples of prior trials. Instead, proactive interference was traceable to the probe value of the prior trial. Overall, the auditory DMS data for the dolphin were functionally similar to results reported for monkeys tested on symbolic, identity, and probe visual DMS tasks. 相似文献

Supplemental reading instruction provides a way to improve the reading outcomes of students at risk for reading difficulties and to meet the challenges produced by increases in student diversity in today’s classrooms. The research–based intervention described in this article includes intensive, explicit, and systematic reading instruction in five areas: fluency, phonemic awareness, instructional–level reading with an emphasis on comprehension, word analysis, and spelling. This intervention was effective in improving the reading skills of low SES, second–grade English monolingual and English–language learners. 相似文献

The mistakes made when attempting tasks often prove to be some of the most invaluable learning experiences. Despite this, outcome and results driven assessment formats largely penalise student performance errors or reward students who succeed by chance. The consequences of this paradigm are visible effects on student relationships with assessment. The student–tutor consensus approach to assessment was introduced to capture student learning achieved ‘from’ assessment to complement the measurement of performance outcomes. This approach parallels student and tutor judgement in a grade negotiation, affording the student an opportunity to share with their assessor what they have learned from the assessment activity. This student self-awareness was then considered alongside the conventional outcome-based score awarded by the tutor to generate a final grade for the assessed activity. Our study evaluated the perceptions of 90 undergraduate students enrolled in the bachelor of paramedic studies, who participated in this novel assessment approach as part of a final-year capstone topic. The results comprehensively indicated value for all aspects of the assessment approach, as well as a recognition that the skills will be useful in their future professional roles. 相似文献

This paper explores the experiences and perceptions of a little-known category of in-service trainee teachers in the Further Education (FE) and Skills sector in England: those who meet the practical teaching requirements of their course mainly through unpaid teaching as ‘volunteers’. The paper reports findings from mixed-methods research which used surveys, interviews and focus groups involving trainee teachers within a large FE–HE partnership. Themes relating to motivations to volunteer, the development of teacher identity within marginal roles, and the risks associated with unpaid teaching are discussed. For increasing numbers of trainees, unpaid teaching provides an opportunity for career entry. However, the quality of teaching experience gained is mixed, with some trainees receiving high levels of support, whilst others experience marginalisation and limitations on their developing teacher identities. The paper highlights the specific challenges to professionalism posed by unpaid teaching within the FE and Skills sector, and relates these challenges to a broader context of insecurity and risk. As work experience becomes an increasingly valuable commodity, this paper illustrates the pressures individuals face as they exchange payment and security for the opportunities volunteering provides. 相似文献

An analysis of selected kinematic variables in national and elite male and female 100-m and 200-m breaststroke swimmers 总被引:1,自引:1,他引:1
The kinematic analysis of competition breaststroke swimming has tended to focus on the mean values of swimming speed, stroke rate and stroke length; values in individual lengths, as well as the start, turns and finish, have largely been ignored. This study includes all such variables and aims to improve the coach's holistic understanding of breaststroke racing by determining the relationships and differences between and within these selected kinematic variables. We also compare 100-m events with 200-m events to determine if there are characteristic differences between them. Competitive breaststroke swimming performances in 100-m events (males: n = 159, finishing time = 65.05 +/- 2.62 s; females: n = 158, finishing time = 74.04 +/- 3.66 s) and 200-m events (males: n = 159, finishing time = 141.47 +/- 6.15 s; females: n = 158, finishing time = 158.66 +/- 7.87 s) were collected and analysed from 12 world, international and national championships. The better 100-m and 200-m breaststroke swimmers were found to demonstrate greater competency in the kinematic variables measured, except stroke kinematics, which were unique to each individual. These findings suggest that coaches should place emphasis on all of the kinematic components in training and that they should attempt to identify the stroke rate to stroke length ratio most appropriate for the individual. Finally, characteristic differences do exist between the 100-m and 200-m events, which has implications for how swimmers might train for each event. 相似文献

In the light of the modern idea of a sovereign and self-transparent subject, the paper evaluates the philosophical and ethical relevance of Bildung . As a first step, (the early) Nietzsche's and Adorno's criticism of Bildung is explicated, a criticism based upon the thinkers' critical stance towards the modern epistemological relation of subject and object. However, neither thinker abandons the concept of Bildung . The second part of the paper accordingly reconstructs Nietzsche's and Adorno's adherence to Bildung understood as a different relationship of subject and object within Bildung . In the paper's concluding reflections there is an attempt to assess the systematic educational consequences, and to shed light on the ethical relevance, of a non-transparent subject of Bildung. 相似文献
