Grasping in the pigeon (Columba livid): Stimulus control during conditioned and consummatory responses     

Brent C. LaMon  H. Philip Zeigler 《Learning & behavior》1984,12(2):223-231

Control of beak opening (gape) and peck location was examined in pigeons. Feeding pecks showed accurate guidance that positioned the seed between the beaks. At the moment of contact with the seed, gape was proportional to seed diameter, although pecks with gape less than seed diameter were more frequent following an increase in seed size during a meal. There were no substantial differences between pigeons trained to keypeck with autoshaping and those trained with operant conditioning procedures. With either procedure, water reinforcement produced keypecks with the beak closed; seed reinforcers of different sizes produced means for gape proportional to the seed diameters. Black or white circular stimuli of different sizes projected as conditioning signals had little influence upon gape, but a greater percentage of responses was directed to white stimuli. These results indicate that visual stimuli elicit and orient the peck, whereas the adjustment of gape also involves the somatosensory stimuli provided during previous experience with a particular reinforcer or food type.  相似文献   

Problems Associated with Multi-Media Data Bases     

Philip G Barker  Harry Yeates 《British journal of educational technology : journal of the Council for Educational Technology》1981,12(2):158-175

Education is intimately associated with communication, and so may utilize any technology that is able to support a process that enables information to be transferred from one location to another. This paper describes the meaning of the term multi-media data base and presents a model of its potential role in aiding message creation for the purposes of communicating educational material using many parallel channels. Some of the problems associated with the implementation of such systems are outlined.  相似文献   

Project Cheddarfield: Supporting Co‐Curricular Themes Through Creative Use of Video Course‐Casting     

Natalie C. Simpson  Philip G. Hancock 《Decision Sciences Journal of Innovative Education》2011,9(2):235-253

This article chronicles the coordination and better integration of existing institutional resources to support cocurricular themes embedded in the provision of a large enrollment, video‐mediated undergraduate operations management (OM) course. The name Project Cheddarfield refers to a 2008 initiative in which two professors team‐taught an OM course to over 600 undergraduates on two different continents through the repeated rapid exchange of digital video between the United States and Singapore. Simultaneously infused in this core curricular delivery were themes of global awareness and study‐abroad, including the promotion of one particular opportunity that bridged the two campuses. This action research narrative spans over 5 years of related activity leading up to the initiative, as this project is best understood as a trajectory, or the evolving result of design adapting to unfolding realities.  相似文献

Teaching imaginary children: University students’ narratives about their Latino practicum children     

Eugene Matusov  Mark Philip Smith 《Teaching and Teacher Education》2007

This study investigates the dialogic processes involved in how teachers talk about their students and what consequences their ways of talking (i.e., “narratives”) may have for their guidance. We take a sociocultural perspective on learning as transformation of students’ subjectivity. Teaching, as a process of guiding and facilitating learning, cannot be effective if the teacher does not actively seek how the student perceives and understands reality. We borrow and adapt from Bakhtin (1999) four narrative ways of talking about others: objectivizing, subjectivizing, problematizing and finalizing. The presence of these narratives in web discussion postings of our pre-service teachers about the Latino children they worked with in a community center are analyzed. We then compare their ways of talking about children with print- and web-based discussions about children made by in-service teachers, model teachers and our pre-service teachers in a school-based practicum. Using mixed quantitative and qualitative methodologies, we found an overwhelming predominance of objectivizing and finalizing in our pre-service teachers’ narratives about the children with whom they work that seems to define a certain pedagogical regime that we call here “teaching imaginary children/students.” This “way of talking” about children seems to be characterized by unchecked speculations guiding instruction that are not tested by finding out from the children themselves how they understand the instruction and the world. These speculations, in turn, can lead to a dogmatic approach towards children.  相似文献   

Genetic influences in different aspects of language development: the etiology of language skills in 4.5-year-old twins     

Kovas Y  Hayiou-Thomas ME  Oliver B  Dale PS  Bishop DV  Plomin R 《Child development》2005,76(3):632-651

The genetic and environmental etiologies of diverse aspects of language ability and disability, including articulation, phonology, grammar, vocabulary, and verbal memory, were investigated in a U.K. sample of 787 pairs of 4.5-year-old same-sex and opposite-sex twins. Moderate genetic influence was found for all aspects of language in the normal range. A similar pattern was found at the low end of the distribution with the exception of two receptive measures. Environmental influence was mainly due to nonshared factors, unique to the individual, with little influence from shared environment for most measures. Genetic and environmental influences on language ability and disability are quantitatively and qualitatively similar for males and females.  相似文献

Philip Pullman 《Children‘s Literature in Education》1992,23(3):157-165

Philip Pullman grew up in what was then Southern Rhodesia, in Australia and in North Wales. He took an English degree at Oxford, and taught in middle schools in that city for thirteen years. He now divides his time between writing and lecturing at Westminster College, Oxford. His novelThe Ruby In The Smoke, the first part of a trilogy, won the International Reading Association Children's Book Award in 1988, and the other parts both made the ALA Best Book for Young Adults list. He has also written two illustrated novels for younger readers, books for teenagers and an adult novel.  相似文献
