Foundational issues in evolution education 总被引:1,自引:0,他引:1
There is a great need for effective evolution education. This paper reviews some of the evidence that demonstrates that need and analyzes some of the foundational semantic, epistemological, and philosophical issues involved. This analysis is used to provide a functional understanding of the distinction between science and non-science. Special emphasis is placed the scientific meaning of the terms theory, hypothesis, fact, proof, evidence, and truth, focusing on the difference between religious belief and acceptance of a scientific theory. Science is viewed as theologically neutral and as not mutually exclusive from religion. Finally, a number of practical recommendations to the classroom biology teacher are presented. 相似文献

Several measures of “success” for a simple game are discussed. Comparisons between players, and between a player and a simulation, can be made in several ways. 相似文献

Parameters pertaining to information processing by human beings have, in the past, been determined by learning and memory experiments with nonsense syllables, number sequences, etc. However, in the real world we are concerned with the processing of meaningful information, not senselles texts. Therefore, the determination of subjective information directly from meaningful material becomes extremely important in the instruction-learning process.This study derives an equation for predicting the subjective textual information contained in a text of material written in the English language. Specifically, this investigation describes, by a mathematical equation, the relationship between the subjective information content of written textual material and the relative number of errors committed by a learner when asked to predict, letter by letter, the content of given textual material. This relationship shows that the subjective information of a given text for a specific learner is directly proportional to the number of wrongly guessed signs made by that learner. This is expressed mathematically by% MathType!MTEF!2!1!+- % feaafeart1ev1aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn % hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr % 4rNCHbGeaGqiVu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq-Jc9 % vqaqpepm0xbba9pwe9Q8fs0-yqaqpepae9pg0FirpepeKkFr0xfr-x % fr-xb9adbaqaaeGaciGaaiaabeqaamaabaabaaGcbaGaamysaiabg2 % da9iaaiodacaGGUaGaaGymaiaabccacaWGfbaaaa!3B57! \[ I = 3.1{\rm{ }}E \] 0935 0212 VWhere: I = Information in bits E = Number of wrongly guessed signsThe application of Shannon's guessing procedure (1951) in this study permits the measurement of the subjective information of a given text for a specific learner. Unlike senseless texts, the subjective information of a meaningful text varies from learner to learner. Therefore, the derived equation permits the measurement of information in terms of a value that is dependent not only upon the inherent qualities of the subject matter, but also upon the internal state of the learner.The derived equation for the English language is then compared to an equation derived by Weltner (1967) for the German language and found to be remarkably similar.This work was, in part, supported by United States Air Force Contract F41609-71-C-0027 entitled Flying Training Research on Airborne and Ground Training Systems, and a research grant from Arizona State University. 相似文献

The transfer of children from primary school to secondary school has long been seen as a problematic area. The National Curriculum was depicted as offering a solution to some of the transfer problems by providing for curriculum continuity across the primary-secondary divide. This paper reports the results of a study of curriculum continuity in one subject, history, now that a National Curriculum has been in place for several years. It reports that teachers continue to see problems with the transfer and that secondary school teachers still incline to a ‘fresh start’ approach to year 7 pupils. There is also some evidence of a lack of curriculum consistency within the secondary schools involved in the research, there are differences between primary and secondary schools in the range of teaching and learning methods employed, there is some decline in pupils’ ratings of their experience of secondary education across year 7 and there are signs of some gender differences in these ratings. The conclusion is that there is a case for saying that the new arrangements have not alleviated the problems associated with the transfer. 相似文献

Lick suppression experiments with rats revealed that the magnitude of both second-order conditioning (Experiment 1) and sensory preconditioning (Experiment 2) was superior when that conditioning was based on backward (US→CS) relative to forward (CS→US) first-order pairings of a CS and US. The superiority of backward relative to forward first-order conditioning on suppression to the higher order cues can be understood by assuming that the magnitude of higher order conditioning was determined by a memory representation of the higher order cues that provided information about the expected temporal location of the US. The results suggest that temporal information such as order between paired CSs and USs was encoded, preserved, and integrated with memory for the higher order stimuli. The relevance of these findings to memory integration in Pavlovian learning, the temporal coding hypothesis (Barnet, Arnold, & Miller, 1991; Matzel, Held, & Miller, 1988), backward excitatory conditioning, and the associative structure that underlies second-order Pavlovian fear conditioning are discussed. 相似文献

One important socio-cultural medium through which young children’s moral understanding is cultivated is parent/child discourse. Of particular interest to us was young children’s use of basic (‘thin’) evaluative concepts (good, bad, right and wrong), which are ubiquitous in everyday discourse and serve as a potential bridge from the non-moral to the moral domain. We investigated 14 2–5-year-old children’s (and their parents’) use of thin evaluative concepts and found that while they frequently used good and bad to morally evaluate other people’s and their own psychological/dispositional states and behaviors—as well as, less frequently, to highlight relevant standards, expectations and rules—they did not use right and wrong. In contrast, a sample of US written and spoken public conversation revealed that adults did. Reasons for this are discussed, along with the frequency of different types of moral evaluations, differences between children and their parents, and age-related trends. 相似文献

This paper explores selective literatures in the two fields of action learning and innovation, and seeks insights into the processes of, and connections between, innovation, engagement and implementation. We searched the action learning articles for references to innovation, beginning with the work of Revans, who highlights the innovation paradox, which becomes a key theme of this paper. We searched the very large innovation literature for references to innovation as a learning process and as a factor in organisational learning. The paper surveys the factors said to enable innovation, and briefly outlines some inhibitors, before considering Revans’ contribution to thinking about innovation. This is followed by a consideration of developments in action learning and innovation since Revans. The findings suggest that paradox theory is a useful way of thinking about innovation, conceived of as a practical problem involving resistances and frequent failures of implementation and adoption, and also propose action learning as a means of working with and addressing paradox. A limitation of this study is its lack of empirical data. Further research could usefully interrogate examples of innovation practices and ask such questions as to why innovation remains so elusive, and how innovative capacities and capabilities can be developed and enhanced. 相似文献
