ABSTRACT As in many schools of education, the Faculty of Education at the University of Alberta has initiated a number of collaborative projects with partnership schools in an attempt to remove the gap between the traditional, university‐based component of practicum courses, and the practice of the school‐based component. One model, described in this paper, uses telecommunications technology to deliver field‐based experiences. Technology‐based, inter‐institutional collaborative projects contain elements of innovation, that are usually managed with reference to change strategy processes described by Fullan (1982), Havelock (1973), Rogers (1983, 1986) ‐and others. However, these processes take time and planning and may actually mitigate against adoption and implementation of rapidly evolving technologies. In this paper, we argue that telecommunications technology‐based, collaboratively developed models of teacher education may be better served by entrepreneurial thinking than by carefully planned change strategies. One such project is described from initiation through implementation, and components of entrepreneurial partnering are suggested. 相似文献

This study reports the participation of 13 secondary science teachers in informal support networks and how that participation was associated with their nature of science (NOS) teaching practices 2 to 5 years after having graduated from the same science teacher education program. The nine teachers who participated in informal support networks taught the NOS at high/medium levels, while the four non-participating teachers taught the NOS at low levels. The nine high/medium NOS implementation teachers credited the informal support networks for maintaining/heightening their sense of responsibility for teaching NOS and for helping them navigate institutional constraints that impede effective NOS instruction. Several high/medium NOS instruction implementers initially struggled to autonomously frame and resolve the complexities experienced in schools and thus drew from the support networks to engage in more sophisticated forms of teacher decision-making. In contrast, the NOS pedagogical decisions of the four teachers not participating in support networks were governed primarily by the expectations and constraints experienced in their schools. Implications of this study include the need for reconsidering the structure of teacher mentorship programs to ensure they do not promote archaic science teaching practices that are at odds with reform efforts in science education.
We have initiated parallel longitudinal studies in Australia (Byrne, PI), the United States (Olson, PI), and Norway (Samuelsson,
PI) of identical and fraternal twins who are being tested in preschool for prereading skills, and in kindergarten, first grade,
and second grade for the development of early reading, spelling, and related cognitive skills. Comparisons of the similarities
of identical and fraternal twins will reveal the relative influence of genetic, shared family environment, and nonshared environment
on individual differences at and across different stages of development. Family and twin-specific environmental information
is also being directly assessed through parent questionnaires and observations by testers. Most of the data collected so far
have been from preschool twins (146 in Australia, 284 in the United States, and 70 in Norway). Preliminary analyses for the
preschool cognitive measures showed reliable genetic influences on phonological awareness and several measures of memory and
learning. In contrast, vocabulary, grammar, and morphology showed significant shared environment and negligible genetic effects.
A print knowledge composite showed both genetic and shared environment influence. 相似文献
Scholars disagree about the manner and extent of environmental structuring of university activities. This study supports arguments
that the environment highly structures the relationships between faculty and the academic products of undergraduate instruction,
graduate instruction, and research. Multiple correlation coefficients exceeded 90 percent for regressions of faculty size
on counts of undergraduate and graduate enrollments and published articles for all universities classified as Research I or
II or Doctoral I or II, demonstrating how constrained is doctoral faculty gross productivity in doctoral universities in the
United States. Possible institutional and technical constraints are discussed. The regressions reveal economies of scale and
economies of scope for some mixes of faculty academic activities, but not for others. Implications on productivity are explored
for university type, control, and science emphasis. A typology for productivity studies is also outlined. 相似文献
In his book Mindstorms (1980) Papert discusses Turtle Geometry as ego-syntonic or fitting the ways of thinking of the child as a geometric knowledge builder. The van Hiele theory (Wirzup, 1976) looks at geometric knowledge building as occuring through a necessary sequence of levels. Thus if Turtle Geometry is ego-syntonic it would seem that one could apply these van Hiele levels to better describe and understand this form of geometry. It is the first purpose of this paper to provide such an analysis.Using Logo to do Turtle Geometry requires that a child (or learner at any level) do geometry through the deliberate use of language. Thus one ought also to be able to relate theoretically levels of language use to Turtle Geometry. It is a second purpose of this paper to relate a language use framework suggested by the work of Frye (1982) to the language activities of Turtle Geometry. 相似文献
