Abstraction and Consolidation     

John Monaghan  Mehmet Fatih Ozmantar 《Educational Studies in Mathematics》2006,62(3):233-258

The framework for this paper is a recently developed theory of abstraction in context. The paper reports on data collected from one student working on tasks concerned with absolute value functions. It examines the relationship between mathematical constructions and abstractions. It argues that an abstraction is a consolidated construction that can be used to create new constructions. Newly formed constructions are fragile entities. In the course of consolidating a construction this student creates connections between the new construction and already established mathematical knowledge and develops a language to describe and guide mathematical actions related to the construction. The resulting abstraction is a more resilient form of the construction and the student is able to justify his assertions. The paper also examines issues in designing tasks to consolidate a construction.  相似文献   

Can students within higher education learn to be resilient and,educationally speaking,does it matter?     

Caroline Walker  Alan Gleaves  John Grey 《Educational studies》2006,32(3):251-264

This paper presents a critical appraisal of resilience and its associated concepts within the context of higher education. It addresses wide‐ranging definitions of resilience, encompassing endurance and adaptability, and seeks to understand how these definitions impact on the learning experiences of students. As theoretical and empirical work on resilience has burgeoned in terms of adolescent experiences of education, the rise of interest has not been matched by that in studies of adult learning, particularly within university settings. This is despite the growing importance of retention studies, which have clear and important links to how well students manage their learning ability in adversity. Realization of the potential embodied in this concept to alter for the better, together with ways of conceptualizing learning and teaching, however, will remain constrained unless teachers within higher education pay attention to the resilience narratives that individual students present, and how teaching strategies can affect their learning trajectories. The paper examines some factors that impact on students’ learning within higher education, and theorizes how teaching and assessment may be adapted to promote resilience in all its forms.  相似文献   

Perceptions of,and reactions to,the educational system and their implications for policy     

John Raven 《Studies in Educational Evaluation》1978,4(1):31-46

The data to be presented was drawn from a survey of nationally representative samples of some 4,000 pupils, most of whom were no longer required by law to be at school, and 1,200 teachers, in the Republic of Ireland. The main purpose of the survey was to collect data relevant to evaluating the post-primary educational system as a whole. Providing such an evaluation was taken to involve, first, assessing what the goals of post-primary education should be, second, obtaining teachers' and pupils' subjective assessments of whether those goals were being attained and, thirdly, asking why the goals were not being better attained. The basic data, which has bee published in three volumes by the Irish Association for Curriculum Development (Raven et al., 1975/ 1976), can be used to illuminate a wide range of basic issues. The present paper deals with one of these. Some others are discussed in Raven (1977b).  相似文献

That exchange concerned the program, recently announced by the Teachers Insurance and Annuity Association-College Retirement Equities Fund (TIAA-CREF), to promote diversity on the governing boards of the public corporations in which it invests.  相似文献   

Teachers’ cultural differences: case studies of geography teachers in Brisbane,Changchun and Hong Kong     

Lam  Chi Chung  Lidstone  John 《Asia Pacific Education Review》2007,8(2):178-193

The primary purpose of this exploratory study is to identify variations in the ways in which individual teachers in different educational contexts interpret their curriculum and plan their lessons and in particular to explore the possibility that cultural differences as identified by Hofstede (1991) may be a contributing factor to understanding how teachers understand their work. “Educational reform” has become a catchphrase in the Anglo-American world, including the United States, Canada, Australia, and England and Wales, as well as in the Confucian Heritage Areas such as Mainland China, Singapore, Hong Kong, and Taiwan. Across the world, the educational reform measures being implemented are surprisingly similar. This paper describes a study of how geography teachers in Queensland, Australia, Hong Kong, and Changchun, China, plan their lessons and curriculum. From classroom observations and interviews with the teachers involved, we confirmed marked differences in each location regarding their cultural traits of power distance, individualist and collectivist preference and uncertainty tolerance, and that these traits appear to be highly influential in their curriculum planning. Despite the small scale of this study, we contend that there are good reasons for caution before national education systems import policies and curriculum reform initiatives from other countries for unthinking adoption.  相似文献   

Technology Knowledge and Use: A Survey of Science Educators     

Odom  A. Louis  Settlage  John  Pedersen  Jon E. 《Journal of Science Education and Technology》2002,11(4):391-398

The purpose of this study was to determine the current state of technology use and know-how among members of the Association for the Education of Teachers in Science. A web-based survey site and an e-mail merge invited members to participate in the study. The survey examined the differences between current and desired levels of knowledge about using technology as an instructional tool, to support research, to enhance productivity in classroom applications, and to enhance data collection and analysis. Large mean differences about using technology as an instructional tool were found, including: (1) teaching students at a distance, (2) database applications, and (3) desktop publishing. Small mean differences were found for telecommunications and word processing.  相似文献   

Computer‐assisted distance education: off‐line and on‐line American experiences     

James Andrews  John Strain 《Distance Education》1985,6(2):143-157

Computer‐assisted learning is having positive effects in distance education. Increased completion rates and enrolments at the Center for Independent Study, University of Missouri can be attributed to successful implementation of off‐line and on‐line systems. The Missouri system is compared to those in other distance teaching institutions and the strengths and weaknesses of the system are analysed.  相似文献   

Reflections on the process of visual design     

Nicholas Tomlinson  John Stevens 《Instructional Science》1972,1(1):89-119

In this article, we are primarily concerned with the kinds of problems which lend themselves to solutions in visual, graphic terms. Essentially, they may be described as problems in communication which the designer attempts to solve by means of printed words or symbols, by the use of appropriate pictorial images or by exploiting audio-visual techniques.The author are practising designers who also share an interest in the teaching of graphic design; and these interests have determined the form of the discussion which follows. Some observations about the nature of design itself, about the various procedures available to the designer in tackling the problems which are brought to him, are illustrated with brief case histories selected from among those which have directly concerned the authors in the recent past. From these, they have ventured to draw some general conclusions about the possible range and scope of the contribution which the graphic designer may be expected to make-now, and in the future-to the solution of problems in visual communication.  相似文献   

The Role of Visual Indicators in Dual Sensory Mode Instruction     

Hyun‐Ju Jeung  John Sweller 《教育心理学》1997,17(3):329-345

Advances in our knowledge of the structure of working memory suggest that under some circumstances, effectively more processing capacity is available to learners if instructional materials use multiple information modes (e.g. auditory and visual) instead of equivalent single mode formats. This paper examined this modality effect from a cognitive load perspective in three experiments using geometry instruction. In accordance with cognitive load theory, it was predicted that the additional processing capacity provided in an audio/visual format would only enhance learning if mental resources were not devoted to extensive visual based search in order to coordinate auditory and visual information. Using two different areas of geometry, Experiments 1 and 2 found that if visual search was clearly high, then audio‐visual instruction was only beneficial if visual indicators in the form of electronic flashing were incorporated into the instructional format. Under high search conditions, a standard audio/visual format without the aid of flashing proved no better than visual only instruction. Experiment 3 attempted to clarify earlier results by using instructional materials trivially low in visual search. Data indicated that a standard, audio‐visual format resulted in superior learning to a visual only format. There was no beneficial effect of electronic flashing in Experiment 3, suggesting that visual indicators were not necessary in areas of low visual search. It was concluded that cognitive load as determined by visual search established the effectiveness of visual indicators.  相似文献   

Using the newspaper to support children's emerging literacy     

June Rose Richie  Janet E. Foster  John M. Johnston 《Early Childhood Education Journal》1991,19(2):28-31

Young children's literacy development involves emerging knowledge, skills, and attitudes about both written and oral language. However, until relatively recent years, children's oral language development has received the lion's share of attention in most early childhood programs. What young children know about written language and their natural ability to learn about writing and reading have been underestimated and misinterpreted and so have received little developmentally appropriate support from early childhood program administrators, teachers, parents, and the public.June Rose Richie is Associate Professor of curriculum and instruction, while Janet E. Foster is Assistant Professor and John M. Johnston is Professor of early childhood education, at Memphis State University, Memphis, TN.  相似文献
