The first year of a 5 year professional development project for elementary teachers in two mid-western states integrated a bridge of two distinctly different distance education networks (T-1 and fiber optics) to provide science professional development for elementary school teachers in rural communities. Interactive television (ITV), the title given to the distance component, consisted of a series of twenty-four, 2 h presentations by scientists and content specialists. It provided expansion to the science pedagogical content knowledge of the elementary teachers involved. Eighty-five teachers in 38 school districts from the two states completed individual surveys following the final ITV session. Analysis of variance of participants post-session survey scores yielded differences (p < 0.05) on the subscales measuring perceived effectiveness of using distance education for professional development purposes and years of teaching experience. Teachers with over 20 years of classroom experience perceived the use of distance education technologies for science professional development to be more effective than teachers with 16–20 years of classroom experience. These results might suggest another digital divide. 相似文献

The voucher model of financing schooling is becoming increasingly common throughout Latin America, with at least 12 countries using vouchers or voucher-like schemes. The present study focuses on the voucher models of Colombia and Chile, which have the most extensive programs of this type and those of the longest standing in the region. Using empirical evidence, the author compares the two models along four evaluative dimensions: educational quality, segregation, choice and socialization. After weighing the successes and weaknesses of each system, he concludes that, among other characteristics, the most effective and equitable voucher model features: (a) a flexible interpretation of educational quality; (b) financial grants which target solely the poor; (c) vouchers which cover the entire cost of tuition; (d) open enrolment at participating schools; (e) the participation of both secular and religious private schools; (f) accessible and meaningful information to parents; and (g) strong systems of accountability. 相似文献

This study investigated the instructional preferences of full time adult credential students after they took a live course
called Principles of Adult Education at California State University, Long Beach, (CSULB) in the fall semester of 2002. These
full time adult credential students had been working on their adult teaching credentials to meet the competencies specified
by the California Commission on Teacher Credentialing. The course introduced students to Andragogy developed by Malcolm Knowles
out of the andragogical model, developed by Lindeman (1926). The study used Principles of Adult Learning Scales (PALS), advanced
by Gary Conti in 1983 to measure instructional preferences. Data were collected from 30 (100% of 30) full time adult credential
students enrolled in a live course to, determine their instructional preferences of helping adults learn. The results of the
study showed in most cases these adult learning professionals taught adult students andragogically: in some cases they taught
adult students pedagogically. 相似文献

In spite of the growing body of research on loneliness, the relationship between the phenomena of loneliness and boredom has not been sufficiently addressed, especially in respect to children. The question, “How does the child’s experience of boredom stand phenomenologically in relation to the experience of loneliness?” is explored from a hermeneutic phenomenological perspective. A critical examination of the literature regarding the phenomenology of both loneliness and boredom provides a theoretical background to the study. Elementary school children’s experiential accounts of loneliness and boredom are collected through research conversations. An original interpersonal communication board game is devised and used to initiate these conversations. The themes of loneliness and boredom emerged in a process of phenomenological reflection based on the participants’ lived experiences, the author’s personal experiences, and experiential accounts available in the literature. Distinctions between the two phenomena are derived from the exploration of these themes. Both boredom and loneliness are viewed as important pedagogical ingredients in the formation of the child’s inner self. 相似文献

Privatisation,Decentralisation and Education in the United Kingdom: The Role of the State 总被引:1,自引:0,他引:1

Since the early 1950s, the axis centralisation–decentralisation, especially as thematised in the work of Isaac Kandel, has represented a major focus of comparative studies in education. Kandel argued that issues relating to the internal conduct of the classroom (interna ) should, so far as possible, be decentralised, while issues relating to administration, school structure and organisation of the educational system (externa ) might safely be centralised. After 1988, successive governments in the United Kingdom have undertaken reforms which have placed more central control on the curriculum and even methods of teaching (interna ), while school finance and administration (externa ) have been devolved to the school level. The present essay argues that a simplistic approach to centralisation and decentralisation is not likely to be fruitful. Instead, we should acknowledge the role of the State in creating a permissive framework for educational systems. Local action can then be seen as part of a policy accommodating or resisting the implications of that framework. 相似文献

It is said that “absence makes the heart grow fonder.” But, when and why does an absent event become salient to the heart or to the brain? An absent event may become salient when its nonoccurrence is surprising. Van Hamme and Wasserman (1994) found that a nonpresented but expected stimulus can actually change its associative status—and in the opposite direction from a presented stimulus. Associative models like that of Rescorla and Wagner (1972) focus only on presented cues; so, they cannot explain this result. However, absent cues can be permitted to change their value by assigning different learning parameters to present and absent cues. Van Hamme and Wasserman revised the Rescorla-Wagner model so that the α parameter is positive for present cues, but negative for absent cues; now, changes in the associative strength of absent cues move in the opposite direction as presented ones. This revised Rescorla-Wagner model can thus explain such otherwise vexing empirical findings as backward blocking, recovery from overshadowing, and backward conditioned inhibition. Moreover, the revised model predicts new effects. For example, explicit information about the absence of nonpresented cues should increase their salience (that is, their negative α value should be larger), leading to stronger associative changes than when no explicit mention is made of cue absence. Support for this prediction is detailed in a new causal judgment experiment in which participants rated the effectiveness of different foods’ triggering a patient’s allergic reaction. Overall, these and other findings encourage us to view human causal learning from an associative perspective. 相似文献

We explored response rate as a possible mediator of learned stimulus equivalence. Five pigeons were trained to discriminate
four clip art pictures presented during a 10-sec discrete-trial fixed interval (FI) schedule: two paired with a one-pellet
reinforcer, which supported a low rate of responding, and two paired with a nine-pellet reinforcer, which supported a high
rate of responding. After subjects associated one stimulus from each of these pairs with a discriminative choice response,
researchers presented two new clip art stimuli during a 10-sec FI: one trained with a differential reinforcement of low rate
schedule (DRL) after the FI and the other trained with a differential reinforcement of high rate schedule (DRH) after the
FI. Each of the stimuli that were withheld during choice training was later shown to see if the choice responses would transfer
to these stimuli. The results suggest that response rate alone does not mediate learned stimulus equivalence. 相似文献

This paper discusses the ways in which inner‐city, ethnically diverse, working‐class girls’ constructions of hetero‐femininities mediate and shape their dis/engagement with education and schooling. Drawing on data from a study conducted with 89 urban, working‐class young people in London, attention is drawn to three main ways through which young women used heterosexual femininities to construct capital and generate identity value and worth; namely, investment in appearance through ‘glamorous’ hetero‐femininities, heterosexual relationships with boyfriends, and the ‘ladettte’ discourse. We discuss how and why young women’s investments in particular forms of heterosexual working‐class femininity can play into their disengagement from education and schooling, drawing particular attention to the paradoxes that arise when these constructions play into other oppressive power relations. 相似文献

This article introduces a research study on student model formation and development in introductory mechanics. As a point
of entry, I present a detailed analysis of the Long Decay Model of one-dimensional projectile motion. This model has been
articulated by Galileo (in De Motu) and by contemporary students. Implications for instruction are discussed.
