Categorical color coding by pigeons     

Thomas R. Zentall  Charles A. Edwards 《Learning & behavior》1984,12(3):249-255

Pigeons were trained on two independent tasks. One involved red and yellow hues, the other involved blue and green hues. For half of the birds, the two tasks were the same (i.e., both tasks were either matching-to-sample, or oddity-from-sample). For the remaining birds, the two tasks were different (i.e., one task was matching-to-sample; the other task was oddity-from-sample). Following acquisition, the pigeons were exposed to test trials on which either the correct or the incorrect comparison hue was replaced with one of the hues from the other task. On yellow-sample trials and on green-sample trials, the pigeons performed as if they had a common code for yellow and green. When there was one comparison available that was appropriate to the “yellow/green” code, performance remained high; but when either both comparisons or neither comparison was appropriate to the “yellow/green” code, performance dropped. The pigeons also tended to code red samples as green and to code blue samples as yellow. The results indicate that pigeons can categorically code colors under conditions that rule out a failure to discriminate among the colors.  相似文献

Physiotherapy Student Clinical Education: the influence of subjective judgements on observational assessment     

Helen A. Alexander 《Assessment & Evaluation in Higher Education》1996,21(4):357-366

The process of assessing students on clinical placements has to date been under‐researched. In particular, while the involvement of subjective judgements in assessing students has been discussed in the literature, there has been no attempt to look for systematic evidence. This paper comprises the first attempt to relate judgement theory to the assessment of vocational education. Preliminary results demonstrate that physiotherapy assessors made subjective judgements of their students, that these contributed to the determination of assessment grades, and that in certain cases these judgements were erroneous. The relationship of these subjective judgements to the awarding of grades via a supposedly objective assessment instrument is not yet known. Given the widespread use of such assessment instruments across different professions, the question raised is whether all observational assessment systems suffer from similar problems. If students are being judged on criteria not included on assessment instruments, perhaps the other criteria being used need to be made more explicit.  相似文献

A CASE FOR SELF‐ASSESSMENT BASED ON RECENT STUDIES OF STUDENT LEARNING     

Helen Boyd  John Cowan 《Assessment & Evaluation in Higher Education》1985,10(3):225-235

An account of an experiment in self‐assessed learning where the lecturer used his authority to give his students responsibility for their own assessment. Students were expected to set their own goals, week‐by‐week, and prepare a self‐assessment, which was open to questioning and discussion by other members of the group, but which involved only the individual student in the final decision.

The difficulties encountered are clearly stated, but the final judgment is that only such methods can achieve deep processing in Higher Education. It is also argued that conventional methods of evaluation are inappropriate for this style of learning.  相似文献   

Teaching the design and interpretation of graphs through computer-aided graphical data analysis     

David F. Jackson  Billie Jean Edwards  Carl F. Berger 《科学教学研究杂志》1993,30(5):483-501

Graphs are one of the primary means of exploration and communication in the practice of science, but students in science laboratories are customarily taught only the low-level mechanics of constructing a single kind of graph when given a table of information. The use of a microcomputer can relieve the drudgery of plotting, allowing students to pursue higher-level issues in the design and interpretation of graphs through repeated “thought experiments.” We introduced computer-assisted graphical data analysis to inner-city high school students with weak math and science backgrounds, emphasizing the dynamic manipulation of various kinds of graphs to answer specific questions. Drawing on extensive recordings and classroom observations, we describe examples of the performance of these students on open-ended problem-solving tasks in which graphs can be used to arrive at meaningful answers to applied data analysis problems.  相似文献

Learning about the past: exploring the opportunities and challenges of using an outdoor learning approach     

Richard Harris  Helen Bilton 《Cambridge Journal of Education》2019,49(1):69-91

This paper examines the potential of outdoor learning for supporting children’s understanding of and attitude towards history. A class of primary school children participated in an intensive experiential, residential history programme. A range of data was collected before, during and after the residential programme, and the findings suggest that the experience had a positive impact on the children’s attitude towards history and enabled many of the children to be able to easily recall highly specific factual knowledge. However, the children’s understanding of history as a provisional construct was not developed, as it was not a strong feature of the programme. Nor was the experiential nature of the experience fully exploited. Overall the study suggests that such a programme has the potential to support children’s learning of the past, but a deeper understanding of history, drawing on the benefits of outdoor learning pedagogy, needs to be planned for more explicitly.  相似文献   

Fees,flows and imaginaries: exploring the destination choices arising from intra-national student mobility     

Allan Findlay  Helen Packwood  David McCollum  Glenna Nightingale  Scott Tindal 《Globalisation, Societies & Education》2018,16(2):162-175

ABSTRACT

Are intra-national student flows driven by the same forces as international student mobility? This paper addresses this question by analysing cross-border student mobility in the UK. The paper identifies four principles that one might expect to drive the destination choices of students from Scotland enrolling in English universities. Following a statistical analysis of student destination choices, it is argued that cross-border moves from Scotland to England are stimulated by some of the same global forces as international student mobility (such as a desire to accumulate cultural capital), but in terms of destination choice the imaginaries held by Scottish students of ‘good’ places to study in England to accumulate cultural capital are constructed differently from the imaginaries of international students.  相似文献
