This article describes perspective and imagery thinking strategies taught during Guided Reading lessons. These strategies are designed to enhance comprehension by giving students techniques for manipulating meaning. Social and physical perspective thinking strategies allow students to identify and apply a variety of perspectives, while imagery thinking strategies allow students to re‐view meaning through the application of still, moving and melting images. Comment from teachers and students involved in a project designed to trial these strategies indicate they may be one way of raising standards in English. 相似文献

General system theory: Toward a conceptual framework for science and technology education for all 总被引:2,自引:0,他引:2
In this paper we suggest using general system theory (GST) as a unifying theoretical framework for science and technology education for all. Five reasons are articulated: the multidisciplinary nature of systems theory, the ability to engage complexity, the capacity to describe system dynamics and change, the ability to represent the relationship between the micro-level and macro-level of analysis, and the ability to bring together the natural and human worlds. The historical origins of system ideas are described, and the major concepts of system theory are mapped; including the mathematical, technological, and philosophical constructs. The various efforts to implement system thinking in educational contexts are reviewed, and three kinds of learning environments are defined: expert presentation, simulation, and real-world. A broad research agenda for exploring and drawing-out the educational implications of system thinking and learning is outlined. The study of both real-world and simulated learning environments is advocated. 相似文献

This paper reports the results of a study of teacher opinions about the features considered important in an ideal textbook.
A survey of Queensland high school teachers revealed that they favoured texts that focus on student cognition and which provide
useful features such as exercises and practical activities. Differences were found between the preferences of Queensland teachers
and the preferences of teachers reported in two American studies. The significance of these differences for writers and publishers
is discussed.

During the early 1980s in Australia there was a new wave of expectancy about primary science as new curricula were being considered or introduced and research findings were beginning to identify new directions for both teaching and research. In an expression of this, six authors were invited to present papers to a symposium on primary science held in 1984 to address the question: “What do you believe should be the state of primary science (in Australia) in 1995 and what are the steps which need to be taken to achieve the desired state?” This study set out to identify what had been said at that time, to compare that with actual developments, and to identify possible future directions for research. Relevant publications includingResearch in Science Education were analysed as a means of comparing what had happened since 1984 with the hopes of those authors. It was only in the latter half of the decade that some of the scenarios painted by the authors in 1984 began to emerge. A key implication for the research community drawn from the analysis shows that science education researchers have tended to neglect working in collaboration with education departments and authorities for the improvement of primary science education. 相似文献

Changes in affect toward a particular stimulus can take place very rapidly through Pavlovian conditioning, if presentation of the conditioned stimulus (CS+) paired with the unconditioned stimulus (US) is accompanied by presentation of a “CS?,” another value of the same dimension as the CS+ but not paired with a US. This effect has considerable generality. It has been observed in terms of both olfactory and visual CSs, in terms of appetitive as well as aversive conditioning, and for adult as well as infant rats. The CS? effect has seemed especially important for infants, which may be related to the general tendency for infants to exhibit less stimulus selection than older animals. Finally, the CS? effect has enabled the development of a simple test of short-term retention that can quite effectively assess memory for either incidental or target events. These tests so far have indicated a clear ontogenetic decrease in rate of forgetting over short intervals, corresponding to the well-known development-related decrease in forgetting over long intervals (infantile amnesia). The tests also have shown that short-term forgetting of intentional and target events is surprisingly similar, with some indication of more rapid forgetting for the incidental events. Alternative interpretations of the CS? effect and some preliminary tests of these interpretations are discussed. 相似文献

Executive functions (EF) have been studied extensively in children and adults. However, EF tasks for young children can be difficult to administer and interpret. Espy (1997, Developmental Neuropsychology, 13, 495–499) designed the Shape School task to measure inhibition and switching in preschool-aged children. Shape School presents cartoon-like characters that children must flexibly name by their color, their shape, or both, depending on cues that indicate the appropriate rule. Shape School has been found to be age sensitive as well as predictive of performance on other EF tasks. We presented a computerized analogue of Shape School to seven rhesus macaques. Monkeys were trained to categorize characters by color or shape, or to inhibit this response, depending on whether the characters had eyes open, eyes closed, or wore hats. Monkeys performed above chance on the inhibition and switching components of the task. Long runs of a single classification rule and long runs of noninhibition trials had no significant impact on performance when the rule changed or inhibition was required. This nonverbal adaptation of Shape School can measure EF in nonhuman animals and could be used in conjunction with other EF tasks to provide a clearer picture of both human and nonhuman executive functions. 相似文献

AbstractThe spread of online disinformation is one of the 10 global risks of the future according to the World Economic Forum, and 51% of experts believe that this situation will not improve in the coming years. By 2022, half of the news will be fake news. In terms of users, young people and adults have problems understanding where the information they find online comes from and what sources to trust or not. In order to ascertain the degree of credibility that young users in Andalucía give to information, this study presents the results of the evaluation of online news by university students pursuing degrees in communication and education (N = 188), using the CRAAP test. The data reveal differences in gender and degree programme in the credibility assigned to the news. The conclusion is that university students have difficulty differentiating the veracity of the sources, in line with previous studies, with fake news earning higher ratings than real news. 相似文献
