Human Self-Assessment in Multiple-Choice Testing   总被引:1,自引:0,他引:1  
Research indicates that the multiple-choice format in itself often seems to favor males over females. The present study utilizes a method that enables test takers to assess the correctness of their answers. Applying this self-assessment method may not only make the multiple-choice tests less biased but also provide a more comprehensive measurement of usable knowledge-that is, the kind of knowledge about which a person is sufficiently sure so that he or she will use the knowledge to make decisions and take actions. The performance of male and female undergraduates on a conventional multiple-choice test was compared with their performance on a multiple-choice self-assessment test. Results show that the difference between test scores of males and those of females was reduced when subjects were allowed to make self-assessments. This may be explained in terms of the alleged difference in cognitive style between the genders.  相似文献

In two experiments with rats, we examined the developmental emergence of conditioned freezing following trace and short-delay conditioning and also included a long-delay comparison group. In the short-delay and trace groups, a 10-sec conditioned stimulus (CS) was paired with shock; for the trace rats, a 10-sec trace interval followed CS termination. The long-delay groups received a 20-sec CS paired with shock, to equate for the longer interstimulus interval (ISI) in the trace group. Trace conditioning emerged later in development than did short-delay conditioning (see Moye & Rudy, 1987). Importantly, long-delay conditioning emerged in parallel with trace conditioning, at a similar time, and with similar strength. These findings suggest a role for the longer ISI, as opposed to the unfilled gap per se, in the late emergence of trace conditioning. The role of the hippocampus in trace conditioning and the possibility that young rats encode the temporal relationship between CSs and unconditioned stimuli are also considered.  相似文献

The academic achievement places children on a positive trajectory for their lifespan. The aim of this study was to examine the academic trajectories of children in out-of-home care (OOCH) and whether kinship care has a protective effect relative to nonkin foster care. The sample analyzed for this study consists of 519,306 racially diverse youth in North Carolina schools 8 to 11 years old in the school year 2009–2010 (e.g., 27% African American, 12% Latinx, 53% White). Four longitudinal administrative data sources were merged to create this unique sample. Multilevel modeling revealed no difference between formal and non-OOHC, but showed differences between nonkin foster, informal, and non-OOHC. Children’s academic performance who reside in formal kinship care is similar to children in non-OOHC.  相似文献

This paper describes programmable multimedia systems, developed at the University of York, which are used extensively for teaching on a variety of music technology and mainstream engineering courses. Software and hardware systems are described for the physical modelling of acoustic spaces, and for constructing interactive synthesis and signal processing networks. Details are given on how these have been successfully integrated into higher education programmes at York.  相似文献

ABSTRACT

Correspondence education, or learning by post, lasted over 100 years in the UK; it had its roots in the nineteenth century, peaking in the mid-1960s. It was also widespread, numbering hundreds of thousands of enrolments, significantly increasing access to higher education. Yet it has been marginalised in accounts of British higher education. This is partly because it was largely private and for-profit and so distinct from the public education system, while the state declined to play any significant role in its oversight. Consequently, little official data concerning correspondence education has ever been available. This paper constructs an account of the history of correspondence education in the UK in terms of its development as a form of academic and professional provision, and its regulatory framework. The paper also considers the reasons for the eventual demise of the correspondence education sector following changes in teaching methods, and the impact of digital technology.  相似文献

Abstract

Purpose: To identify various organizational climatic factors responsible for role performances of veterinary officers in Andhra Pradesh, India.

Design/methodology/approach: Study was conducted in 11 selected districts. Data were collected from 220 respondents through a pretested interview schedule and subjected to correlation and multiple regression to draw valid inferences. Organizational climate was measured by using the index specially prepared for the study.

Findings: Around 76% of the respondents perceived that the organizational climate prevailing in the department of animal husbandry was favorable. Leadership, teamwork and trust had significant contribution towards perception of organizational climate. The respondents were least satisfied with motivation, decision-making and goal setting components of the organizational climate. The model with seven variables out of 16 independent variables was a good fit with R square of 85.59%. Work motivation, persistence disposition, participativeness, job satisfaction, physical facilities availability and timeliness of availability of facilities were found to have significant positive influence while job stress had significant negative influence on perceived organizational climate.

Practical implications: This investigation has an organizational and social significance for development of livestock organizations not only in India, but also to other SAARC countries as well.

Originality/value: No empirical evidence on inter-relation between organizational climate and job performance of veterinarians is available at present in Andhra Pradesh.  相似文献

Abstract

Purpose: This article outlines the development of extension as a discipline in Australia, its organization, and the ideological changes that have occurred from the second half of the nineteenth century through to the present.

Design/Methodology/Approach: It considers the evolution of extension across the different states of Australia from a national perspective and describes how the research development and extension (RD&E) complex has rotated through cycles of crises, highs, awakenings in thought and practice, and periods where achievements and institutions unravel.

Findings: Discussed is the tension between public and private sector extension, as well as the successes and failures of various paradigms. It considers the impacts of different agricultural policy on Australian agricultural RD&E across the decades. In particular it deals with the current ‘unravelling’ of the agricultural RD&E system in Australia, and tries to anticipate future demands on agricultural extension and how these services might be delivered into the future.

Practical Implications: The article challenges the reader to consider the discipline of extension as a subset of the greater society in which it exists. It provides an insight into how the agricultural research, development and extension capacity of a nation can be observed to ebb and flow over generations in accord with the rhythm of society.

Originality/Value: The article presents a perspective that has not been fully captured or understood until now.  相似文献
