In an era where technology is advancing at a rapid pace, and where information is readily accessible on the World Wide Web, educators should be capitalizing on these resources for gifted students. This paper proposes a conceptual framework to support individualized and independent learning within a network of peers that will provide challenging interactions through extensive use of online learning. Online resources and technologies promote the exploration of new concepts and sharing of new learning with a group of motivated and “like‐minded” peers. 相似文献

This article describes the development and implementation in the schools over a 20-year period of the Energy Source Program,
a comprehensive K-12 energy education curriculum. The program was developed beginning in 1980 using state-of-the-art development
procedures for that time and has been used to date by more than 12 million American students to learn about energy and energy
issues. End-of-unit posttest scores for the elementary and high school units averaged above 80% for their field tests. Data
obtained from a large sample during the first three years of installation of the program in the schools indicated that posttest
scores remained at a level during installation similar to that during the field-test phase. A study conducted in the early
1990s by an independent research organization to assess the program's long-term effects revealed that grade 6 students who
had used one or more units from the program had significantly greater energy knowledge and better energy conservation habits
than students who had not used any units. A set of 10 guidelines are offered for long-term instructional development and implementation
projects.

Experience of assessment and evaluation is outlined in the belief that it may indicate where improvements are desirable. Comments are made on the selection of examiners, the need for greater openness and the lack of an agreed code of practice. Finally, suggestions are put forward which would, if accepted, raise the professionalism, status and influence of the evaluator while, at the same time, providing protection for student and institution from personal evaluator bias. 相似文献

Ducklings (Anas Platyrhynchos domesticus) older than the so-called critical period (Days 1 and 2 posthatch) were exposed to an imprinting stimulus after various experimental histories. The first study found that in previously isolated 10-day-old subjects the stimulus exhibited the same capacity to reinforce an operant response and to generate a burst-like pattern of responding as in ducklings imprinted to it on Day 1. In Experiment 2, an imprinting stimulas exhibited reinforcing capacities in 5 to 10-day-old ducklings that had previously been imprinted to a different stimulus. Most of these ducklings came to prefer the second imprinting stimulus over the first. Experiment 3 revealed that in 5-day-old ducklings with a prior history of imprinting to a different stimulus, the otherwise neutral features of a new imprinting stimulus acquired the same kind of persistent control over distress vocalization that they acquire in younger, naive subjects. In all these studies, the only difference between imprinting in older vs. younger subjects was that in older subjects a novel imprinting stimulus initially evoked fear reactions rather than filial behavior. These findings contradict the traditional view of imprinting as an irreversible process that occurs only during a brief critical period, but are entirely consistent with a reinforcement model of imprinting. 相似文献

Guided by communicated narrative sense-making, the present study explored the themes that characterize adult siblings’ stories about their experiences with sharing care of aging parents. Interviews with 20 adult siblings revealed the varied and emotional nature of their shared parental caregiving stories. Adult siblings primarily constructed meaning of their caregiving experiences by drawing upon three overarching narratives: (1) the narrative of (in)equity, (2) the narrative of ideal versus real, and (3) the narrative of interconnectedness. These findings highlight the need for adult siblings providing care for their parents to work together as a team, exercise empathy in their interactions, and express gratitude for one another’s contributions. Several practical applications are discussed that can help siblings manage and overcome the relational challenges associated with caring for a parent. 相似文献
