This paper considers the circumstances under which science teachers can respond positively and productively to educational policy reforms in the area of science practical assessment. To understand what might be involved in linking science teachers’ assessment capacities and their professional development, we present illustrative data from recent research studies conducted in Singapore and Hong Kong showing contrasting approaches taken in the implementation of reforms in science practical assessment. In Singapore, teachers worked together to select, discuss, clarify and refine their practices as they made decisions about what to teach and assess. In Hong Kong, teachers took a critical stance towards the new policy and learnt from their own experiences in order to build their confidence. With the same policy initiative, one group of teachers focused more on the technicalities of complying with requirements imposed on them while in the other group had their professional consciousness of what they thought was best for their students provoked so that their practices would be transformed. In an attempt to draw lessons for other contexts in supporting the implementation of assessment policy reforms through professional development work, we identify and discuss a range of factors in science teachers’ professional development that arise once in situ professional development work has started. Overall, our intent in this article is to recast assessment reform as a driver or pivot in teachers’ professional development and learning. To do this it is necessary, we argue, to afford teachers’ experiences and the processes involved in learning from them greater emphasis in order to ensure the continuance of innovation in the assessment of laboratory-based work.  相似文献   

The Relation of Mild Traumatic Brain Injury to Chronic Lapses of Attention     

Matthew B. Pontifex  Steven P. Broglio  Eric S. Drollette  Mark R. Scudder  Chris R. Johnson  Phillip M. Oapos;Connor 《Research quarterly for exercise and sport》2013,84(4):553-559

We assessed the extent to which failures in sustained attention were associated with chronic mild traumatic brain injury (mTBI) deficits in cognitive control among college-age young adults with and without a history of sport-related concussion. Participants completed the ImPACT computer-based assessment and a modified flanker task. Results indicated that a history of mTBI, relative to healthy controls, was associated with inferior overall flanker task performance with a greater number of omission errors and more frequent sequentially occurring omission errors. Accordingly, these findings suggest that failures in the ability to maintain attentional vigilance may, in part, underlie mTBI-related cognition deficits.  相似文献   

Self-Controlled Amount of Practice Benefits Learning of a Motor Skill     

Phillip G. Post  Jeffrey T. Fairbrother  Joao A.C. Barros 《Research quarterly for exercise and sport》2013,84(3):474-481

Abstract

Self-control over factors involving task-related information (e.g., feedback) can enhance motor learning. It is unknown if these benefits extend to manipulations that do not directly affect such information. The purpose of this study was to determine if self-control over the amount of practice would also facilitate learning. Participants learned to throw a dart using their nonpreferred hand. The self-control (SC) group decided when to stop practice. The yoked group completed the same number of trials as their SC counterparts. Results revealed the SC group was more accurate during transfer and in recalling the number of trials completed. These findings indicate that self-control benefits extend to factors that do not directly alter task-related information.  相似文献   

Effect of Toe Clips during Bicycle Ergometry on [Vdot]O2 max     

Roger S. Moffat  Phillip B. Sparling 《Research quarterly for exercise and sport》2013,84(1):54-57

Abstract

Previous investigators have yielded conflicting results in testing the hypothesis that the use of toe clips during bicycle ergometry produces a higher maximal oxygen uptake ([Vdot]O ₂ max) than testing without toe clips. Eight men, four competitive cyclists and four competitive distance runners volunteered to participate in three randomized [Vdot]O ₂ max tests: 1) a treadmill running lest, 2) a bicycle ergometer test using standard toe clips, and 3) a test on the same ergometer without toe clips. The highest mean [Vdot]O ₂ max was observed in the treadmill condition as expected. However, no statistically significant difference in mean [Vdot]O ₂ max or performance time was observed between the toe-clip and no toe-clip conditions. Based on these results, the research hypothesis was rejected and no favorable physiological effect may be attributed to the use of toe clips.  相似文献   

Threats to student evaluative judgement and their management     

Gordon Joughin  David Boud  Phillip Dawson 《高等教育研究与发展》2019,38(3):537-549

ABSTRACT

Students’ capacity for making evaluative judgements of their own work is widely acknowledged as central to their learning within programmes as well as being vital to their subsequent professional practice. In higher education literature, the act of evaluative judgement is usually portrayed as a process of deliberative, analytical reasoning requiring student agency and objectivity, typically scaffolded by points of reference such as explicit criteria, rubrics or exemplars. This article challenges this common portrayal of judgement by drawing attention to research from outside higher education on the role of unconscious factors in judgement and decision-making. Drawing from the field of heuristics and bias studies, the article outlines six unconscious factors that have the potential to distort students’ analytical judgement of their work. A recent challenge to the heuristics and bias approach that radically repositions the place of reasoning in judgement is also considered. Since these unconscious factors have received scant attention in higher education literature, the purpose of this article is to draw attention to them, to identify the challenges they pose to current understandings of evaluative judgement, and to outline their implications for enhancing assessment practice.  相似文献   

Factors influencing environmental attitude: The relationship between environmental attitude defensibility and cognitive reasoning level     

James R. Yount  Phillip B. Horton 《科学教学研究杂志》1992,29(10):1059-1078

The purpose of this study was to investigate the relationship between factors believed to contribute to the formation of environmental attitudes by college nonscience majors. Key relationships addressed were the effects of a university environmental studies course on (a) environmental attitudes, (b) the amount of factual information that is brought to bear on an environmental attitude decision (defensibility), and (c) the linkages between the affective and the cognitive domains of freshman and sophomore students. When compared to the control group, the students who attended an environmental studies class did not significantly change their attitudes, but they did exhibit increases in their total [F(3, 132) = 5.91, p < 0.01] and count [F(3, 132) = 4.86, p < 0.01] levels of defensibility. These findings corroborate work performed by Kinsey (1978) and Kinsey and Wheatley (1980, 1984). In addition, students in the environmental studies course who had higher cognitive reasoning scores were more prone to increase defensibility [F(6, 129) = 3.78, p < 0.01]. These data imply a linkage between cognitive and affective domains in the environmental attitude decision-making process.  相似文献   

Our anonymous online research participants are not always anonymous: Is this a problem?     

Phillip Dawson 《British journal of educational technology : journal of the Council for Educational Technology》2014,45(3):428-437

When educational research is conducted online, we sometimes promise our participants that they will be anonymous—but do we deliver on this promise? We have been warned since 1996 to be careful when using direct quotes in Internet research, as full‐text web search engines make it easy to find chunks of text online. This paper details an empirical study into the prevalence of direct quotes from participants in a subset of the educational technology literature. Using basic web search techniques, the source of direct quotes could be found in 10 of 112 articles. Analysis of the articles revealed previously undiscussed threats from data triangulation and expert analysis/diagnosis. Issues of ethical obliviousness, obscurity and concern for future privacy‐invasive technologies are also discussed. Recommendations for researchers, journals and institutional ethics review boards are made for how to better protect participants' anonymity against current and future threats.  相似文献   

A contribution to the history of assessment: how a conversation simulator redeems Socratic method     

Robert Nelson  Phillip Dawson 《Assessment & Evaluation in Higher Education》2014,39(2):195-204

Assessment in education is a recent phenomenon. Although there were counterparts in former epochs, the term assessment only began to be spoken about in education after the Second World War; and, since that time, views, strategies and concerns over assessment have proliferated according to an uncomfortable dynamic. We fear that, increasingly, education is assessment-led rather than learning-led and ‘counter to what is desired’ in an ugly judgemental spirit whose moral underpinnings deserve scrutiny. In this article, we seek to historicise assessment and the anxieties of credentialising students. Through this longer history, we present a philosophy of assessment which underlies the development of a new method in assessment-as-learning. We hope that our development of a conversation simulator helps restore the innocence of education as learning-led, while still delivering on the incumbencies of assessment.  相似文献   

Efficacy of the family viewing concept: A test of assumptions     

Phillip J. Mohr 《Communication Studies》2013,64(4):342-351

This article examines two implicit assumptions on which the family viewing concept appears to be based: (1) children's viewing will subside after the end of the family viewing period, and children will be less likely to be exposed to later, more “mature” programming; (2) broadcasters can and do provide programs toward which children and parents share preferences and which are “appropriate” for the family viewing period (6:00‐8:00 p.m. CST, 7:00‐9:00 in other time zones).

Data gathered in a 1976 survey confirmed the first assumption. However, while the peak period of children's viewing occurred between 6:30 and 8:00 p.m., substantial numbers of the children continued to view television beyond the family viewing period. Less consistent support was found for the second assumption. Above‐average percentages of both parents and children considered thirty‐one of sixty‐eight programs listed on the questionnaires to be “favorites” or “all right,” and nineteen of the thirty‐one were broadcast during the family viewing period. While parents and children may share attitudes toward certain programs, however, it does not necessarily follow that parents consider those programs appropriate for their children. The results of the survey suggest the need for further study of what constitutes “appropriate” programming for family viewing.  相似文献   

Magic Windows and the Serious Life: Rituals and Community in Early American Local Television     

Phillip J. Hutchison 《广播与电子媒介杂志》2013,57(1):21-37

This historical study addresses the social impact of early local television by examining the ritual aspects of its now-extinct entertainment programming genres. The study assimilates several theories of ritual and collective memory to explain how this programming shaped the daily lives of television viewers in postwar America. It examines both the nature and form of this programming and how viewers remember it, largely via Internet-based tribute venues. This perspective helps better explain how such programming created a sense of community among technologically determined viewing audiences, and why it continues to structure the collective and individual memories of former viewers.  相似文献
