The Vice: Some Historically Inspired and Proof-Generated Steps to Limits of Sequences     

Bob?BurnEmail author 《Educational Studies in Mathematics》2005,60(3):269-295

This paper proposes a genetic development of the concept of limit of a sequence leading to a definition, through a succession of proofs rather than through a succession of sequences or a succession of εs. The major ideas on which it is based are historical and depend on Euclid, Archimedes, Fermat, Wallis and Newton. Proofs of equality by means of inequalities precede the notion of limit. For example, the determination of the volume of a pyramid precedes the definition of limit. The algebraic details given here are anachronistically modern, and the notion of a vice between two inequalities which provides the distinctive perspective of this paper would not have been recognized in this form by any of the named mathematicians since it presumes the existence of negative numbers and their comparability in a modern sense with positive numbers.  相似文献

THE USES OF TELEVISION IN TEACHING PSYCHIATRY     

David Goldberg  Bob Kendell  Dr. Peter Maguire 《Learning, Media and Technology》1980,6(1):21-24

The A.U.T.P. Working Party on the Applied Uses of Television was set up after the A UTP/ASME Conference on Undergraduate Education in Psychiatry and Behavioural Science held in Manchester in 1971. A group of Position Papers on the Uses of Television in Teaching Psychiatry has been published by the Working Party (AUTP, 1977), under the chairmanship of Professor David Goldberg. By his kind permission, two of these papers are here reprinted: one concerns the uses of television in undergraduate teaching of psychiatry; the other, ethical aspects of the use of television in psychiatry.  相似文献   

Development of Oral Reading Fluency in Young Children at Risk for Failure     

Chuang Wang  Erik Porfeli  Bob Algozzine 《Journal of Education for Students Placed at Risk》2013,18(4):402-425

The body of knowledge on critical components of reading instruction is broad and deep with phonemic awareness, phonics, fluency, vocabulary, and comprehension serving as building blocks for literacy. The importance of fluent reading (i.e., with speed, accuracy, and proper expression, as well as comprehension) in the formula for success is widely accepted. The purpose of this study was to evaluate oral reading rates in a sample of 2nd-grade children. Using growth curve analysis, we identified models for a combined sample of at-risk and not-at-risk children. Large and important differences in oral reading were evident, but the growth rates remained the same throughout the 2nd- grade; in fact, the gap between at-risk and not-at-risk students remained constant. We discuss the implications of our findings for future research and the improvement of practice.  相似文献   

Early Integration and Other Outcomes for Community College Transfer Students     

Mark M. D’Amico  Sandra L. Dika  Theodore W. Elling  Bob Algozzine  Donna J. Ginn 《Research in higher education》2014,55(4):370-399

The purpose of this study was to explore academic and social integration and other outcomes for community college transfer students. The study used Tinto’s (Leaving college: Rethinking the causes and cures of student attrition, 1993) Longitudinal Model of Institutional Departure and Deil-Amen’s (J Higher Educ, 82:54–91, 2011) concept of “socio-academic integrative moments” to inform the selection and organization of potential predictors. We developed regression models for relationships between demographic and background variables of interest and perceived academic and social integration following the first six weeks at the receiving university. We also included these perceived integration scores in regression models for six outcomes (first and second semester grade point average, first and second semester earned hours ratios, and second and third semester persistence). Academic and previous college background explained the greatest amount of variance in predicting early integration and academic outcomes.  相似文献   

The mind of a plagiarist   总被引：1，自引：0，他引：1  

Jon Baggaley  Bob Spencer 《Learning, Media and Technology》2005,30(1):55-62

The ease with which material may be ‘copied and pasted’ from the Internet into written work is raising concern in educational institutions, and particularly in those disciplines that use online sources and methods in their curriculum. A case of ‘serial plagiarism’ is discussed, in the work of a graduate student in an online distance education program. The complexity of the student’s thinking is emphasized, and the manner in which the case was handled by the teacher and the university. The use of an online plagiarism‐checking technology (Turnitin.com) and the value of such services are discussed. The case illustrates the importance of explaining the precise nature of plagiarism to students, of providing clear warnings about its consequences and of developing a careful institutional approach to plagiarism detection and prevention.  相似文献
