Methods for estimating the number of relevant documents in a collection     

Don Miller  Robert T. Dattola 《Information processing & management》1982,18(4):179-191

Several statistical sampling methods are evaluated for estimating the total number of relevant documents in a collection for a given query. The total number of relevant documents is needed in order to compute recall values for use in evaluating document retrieval systems. The simplest method considered uses simple random sampling to estimate the number of relevant documents. Another type of random sampling, which assigns unequal selection probabilities to the individual documents in the collection, is also investigated. An alternative approach considered uses curve fitting and extrapolation, where a smooth curve is developed which relates precision to document rank. Another curve relates a function of precision to the query-document score. In either case, the curve is extrapolated to the total number of documents in order to estimate the number of relevant documents. Empirical comparisons are made of all three methods.  相似文献

A historical overview of educational psychology     

Don C Charles 《Contemporary educational psychology》1976,1(1):76-88

A historical review of educational psychology might improve understanding of current status and problems. Before American development of the field, the Greeks, Juan Vives in the 16th century, and Pestalozzi and Herbart in the 19th century applied psychological views to educational problems. Despite the absence of scientific psychology in 19th century America, normal schools offered courses purporting to be psychological in content; these courses were supported by textbooks on the subject. James began, and Thorndike developed, the discipline that by the mid-1920s had assumed much of its current form. Journals and academic departments appeared in the first quarter of the century also. The continuing search through the middle of the century for a satisfying professional organization reflected educational psychology's difficulties in establishing an identity. It is not clear even today that the field has “crystallized,” as one writer described it in the 1920s.  相似文献   

Considerations for Faculty Preparing to Develop and Teach Online Criminal Justice Courses at Traditional Institutions of Higher Learning     

Don Hummer  Barbara Sims  Alese Wooditch  K. S. Salley 《Journal of Criminal Justice Education》2013,24(3):285-310

Criminal justice programs at traditional institutions of higher learning have been moving toward offering courses online and, in some cases, placing entire programs online for the better part of the past decade. In competition with for‐profit institutions, many traditional colleges and universities have expanded their distance education programming to include online courses and programs to attract students. As a result, the number of criminal justice students has increased, as have the profits for home institutions. With this growth in the online education market, the criminal justice faculty member has been thrust, willingly or unwillingly, into the world of online teaching—a method of instruction foreign to many instructors. From the authors’ experience at their current (and in the case of the lead author a second) institution, this paper addresses many issues that must be considered by faculty members before embarking on this type of time‐intensive initiative.  相似文献

TWO‐YEAR COLLEGE ATTRITION: DO STUDENT OR INSTITUTIONAL CHARACTERISTICS CONTRIBUTE MOST?     

Anne G. Gates  Don G. Creamer 《Community College Journal of Research & Practice》2013,37(1-4):39-51

This study examined certain effects of seven student pre‐enrollment characteristics and three student‐institutional characteristics on retention status. Path analysis of these longitudinal data was unable to compare favorably with other studies using similar determinants. Certain practical implications of the study also are presented, emphasizing the burden of evidence that suggests that entering student characteristics cannot be used alone to explain the retention decision, that retention programs should be strategically rather than generically focused, and that program holding power may be related to student career consciousness and goal specificity.  相似文献   

Technology-enhanced learning: Rethinking the term,the concept and its theoretical background     

Don Passey 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(3):972-986

This theoretical paper is concerned with problematising the rethinking of theoretical backgrounds associated with one of the commonly used educational technology terms (fields)—technology-enhanced learning—in the wider context of scholarship. Examples will show that the term itself is now used beyond its apparent, stated scope, that it is used in a number of varied ways, and that this is in itself problematic. The ways in which the term is used will be identified, and from these a strategic categorisation to rethink the use of the single term in areas of scholarship (particularly research and teaching) will be proposed, offering terms specifically encompassing the realms in which technologies are being used. From this categorisation, it will be shown that each specific category is based on different conceptions related to or arising from practice. Consequently, ways that theoretical backgrounds should be considered will be explored in each case. While existing theoretical backgrounds enable conceptual underpinnings in some of those cases, in other cases it will be shown that there are currently no fully developed theories or limited theoretical frameworks available. The paper will conclude by identifying key research areas needed if we are to develop and take pertinent aspects of scholarship further forward.  相似文献
