Preweanling and adult rats treat conditioned light-tone combinations differently

Ontogenetic differences in processing light-tone compounds were discovered in preweanling (17-day-old) and adult (60–80-day-old) rats. Suppression of general activity was used as an index of the magnitude of conditioned fear following a single training session in which a CS+ was paired with mild footshock. In Experiment 1, rats were trained on discriminations in which the CS? consisted of a light and the CS+ was either a tone alone (simple discrimination) or a light-tone compound (simultaneous feature-positive discrimination). Adults and preweanlings given each type of discrimination were then tested for fear of the CS? and a target stimulus (tone alone or light-tone compound). Adults in all groups displayed greater fear of the target than of the CS?. Preweanlings, however, discriminated the CS? from the target only when the target was the same as the original CS+. Experiment 2 revealed that age-related differences in conventional stimulus generalization is not a likely explanation for the pattern of results found in Experiment 1. Experiment 3 revealed age-related differences in expressed fear of a serial feature-positive discrimination; adults, but not preweanlings, showed greater fear of the compound than of the CS?. Alternative interpretations of the results from these experiments are discussed, and the general conclusion is that adults appear more inclined to process elements of a compound stimulus selectively, whereas preweanlings seem more likely to process the compound unselectively, with roughly equivalent processing of each element.     

Graduate credit for prematriculation experiences

Although undergraduates often earn academic credit for prior learning acquired through experience, graduate students are rarely afforded that opportunity. Central Michigan University and The University of Northern Colorado are examples of the very few institutions that do accept prior experiential learning toward graduate degrees. The Council of Graduate Schools in the United States adamantly opposes graduate credit for prematriculation experiences; however, the American Council on Education favors the assessment of extrainstitutional learning which has occurred prior to a student's enrollment. Further, the Council for the Advancement of Experiential Learning recently formed a task force to promote experiential learning in the graduate sector. The future for the assessment of experiential learning for graduate credit is indeed favorable.

Emergent patterns of teaching/learning in electronic classrooms

Novel patterns of teaching/learning have emerged from faculty and students who use our three teaching/learning theaters at the University of Maryland, College Park. These fully-equipped electronic classrooms have been used by 74 faculty in 264 semester-long courses since the fall of 1991 with largely enthusiastic reception by both faculty and students. The designers of the teaching/learning theaters sought to provide a technologically rich environment and a support staff so that faculty could concentrate on changing the traditional lecture from its unidirectional information flow to a more collaborative activity. As faculty have evolved their personal styles in using the electronic classrooms, novel patterns of teaching/learning have emerged. In addition to enhanced lectures, we identified three common patterns: (a) active individual learning, (b) small-group collaborative learning, and (c) entire-class collaborative learning.     

The Use of the Microgenetic Method with Children with Disabilities: Discovering Competence

In this paper, we advocate the use of the microgenetic method, a methodology that combines dense sampling of observations across time and extensive trial-by-trial analysis, to examine strategy change in children with disabilities. This methodology has revealed new information about normally achieving children's cognition, such as large individual variability in strategy use among children of the same age and more gradual patterns of strategy change than previously assumed. In this paper, we review data from three different microgenetic studies in the domains of memory, arithmetic, and reading with children with or at risk for mental retardation and normally achieving children. Our review indicates that there are similar sequences of strategy change, similar rates of strategy change, and similar frequency of strategy discovery and use in children with and without mental retardation (compared to mental age peers). Implications are discussed for the use of this methodology to design instructional techniques for children with disabilities.     

Geographical education and ideology in England and Wales

Conclusion If ideology is a nexus of ideas which represent the values of a society and the way that society operates, then clearly such ideas, in so far as they are held by those who have power in society, are bound to affect what is taught within the system of education. This may not be openly avowed, though in totalitarian regimes the education system is determinedly used to enforce the only ideology—that of those in power. The saving grace in a democratic system is that those being educated have access ideologies other than the dominant one. In England and Wales and to some extent elsewhere in the United Kingdom, there is little doubt that the geography curriculum has tended to serve the dominant ideology during the heyday of the British Empire and even during its period of decline in the 1930s and 1940s. In the 1960s and 1970s, an alternative ideology stressing the rights of the underprivileged became manifest in a geography curriculum that was not controlled centrally. The 1980s saw a reversal of this trend by those who had political power, though the reason advanced for the greater control of the curriculum was couched in terms of the economic needs of the nation and the desire to raise standards. But clearly those in power considered that theraison d'être of education was to promote an enterprise culture. However, in practice no ideology is ever pure. When the enterprise culture came into contact with long-cherished ideas of national sovereignty, marrying the two proved difficult. This was reflected in the neutral (not to say negative) position of the national curriculum in geography with respect to the European Union.
