It has been widely documented that accountability systems, including school inspections, bring with them unintended side effects. These unintended effects are often negative and have the potential to undo the intended positive effects. However the empirical evidence is limited. Through a European comparative study we have had the rare opportunity to collect empirical evidence and study the effects (both intended and unintended) of school inspections (a key system of accountability) in a systematic way, across seven countries. We present the findings of the unintended effects in this paper. Survey self-report responses from school principals in each country, with differing school inspection systems, are analysed to measure the prevalence of these unintended effects and to investigate the part played by pressure to do well in inspections. A key finding is that increasing pressure in school inspection systems is associated with the undesired effect of the narrowing and refocusing of the curriculum and instructional strategies. We also show that a proportion of school principals admit to misrepresenting the school in data sent to the inspectorate and show evidence for formalisation/proceduralisation (excessive focus on records) and ossification (fear of experimentation in teaching), although these factors are less related to changes in pressure.  相似文献

This paper is an investigation of understandings of critical thinking from two teaching perspectives: academic staff and tutors. It explores critical thinking as situated within an assessment task in introductory macroeconomics. This study found that while the two academic staff conceptualized critical thinking as a set of concrete cognitive skills, the tutors challenged this notion. Although tutors used the way of understanding critical thinking identified by the academic staff in their teaching and marking, they also discussed broader notions of critical thinking that they saw as a fundamental aspect of the discipline. The paper examines the multiple constructions of critical thinking in this setting and its broader implications.  相似文献

Two experiments were performed to determine the effect of sample duration (0.1, 2, and 4 sec), delay interval (.03, 4, 8, 16, and 32 sec), and type of stimulus (color and shape) on the matching performance of rhesus monkeys. In Experiment 1, the 15 possible delay-duration combinations were randomly presented in blocks of 15 trials. In Experiment 2, each duration was held constant and the five delays randomly presented. Then each delay interval was held constant with the three durations randomly varied. Matching performance increased as sample duration increased (ps < .01 and .005), while length of delay did not significantly affect performance. The type of stimuli paired in the matching test significantly affected performance (ps < .05 and .10) with the shape/shape choices leading to the poorest performance. Stimulus discriminability and amount of training with brief sample durations were implicated as significant determinants of matching performance.  相似文献

Caption rate and text reduction are factors that appear to affect the comprehension of captions by people who are deaf or hard of hearing. These 2 factors are confounded in everyday captioning; rate (in words per minute) is slowed by text reduction. In this study, caption rate and text reduction were manipulated independently in 2 experiments to assess any differential effects and possible benefits for comprehension by deaf and hard-of-hearing adults. Volunteers for the study included adults with a range of reading levels, self-reported hearing status, and different communication and language preferences. Results indicate that caption rate (at 130, 180, 230 words per minute) and text reduction (at 84%, 92%, and 100% original text) have different effects for different adult users, depending on hearing status, age, and reading level. In particular, reading level emerges as a dominant factor: more proficient readers show better comprehension than poor readers and are better able to benefit from caption rate and, to some extent, text reduction modifications.  相似文献

Student belonging and engagement has received increased attention in the context of an expanding and more diverse higher education student population. Student retention is regarded as a priority with many universities augmenting their retention strategies to instil a sense of belonging. This article provides insights into first year Business Management students’ experiences of starting their degrees and retention interventions at a university in the South of England. It is based on findings from an ongoing study that applied Wenger's social theory of learning and adopted an appreciative inquiry approach to focus group interviewing to investigate students’ perceptions. Students developed a sense of belonging, constructed learner identities, made sense of their learning and gained confidence, but also experienced instances of tension and frustration that raise questions about the extent to which sociality practices within evolving communities of practice can address diverse engagement and identity development needs and mitigate disengagement.  相似文献

Although the principle of holography was conceived as long ago as 1947, interest was limited until the advent of the laser in 1960 made possible the off-axis holography widely used today. Since then holography has found many applications and become so well known outside the laboratory as to be a recognized art form. Within the last few years considerable progress has also been made in acoustic holography.  相似文献
