Remembering in California sea lions: Using priming cues to facilitate language-like performance     

Ronald J. Schusterman  Evelyn Hanggi  Robert C. Gisiner 《Learning & behavior》1993,21(4):377-383

Two sea lions(Zalophus californianus) were trained to respond to relational commands fey bringing the last designated object (transport item, or TI) to the earlier designated object (goal item, or GI). Most errors on this task involved forgetting of the GI due to interference from memory for the TI. We reasoned that instructing the animals to act directly on the same object several times in single-object commands immediately before a relational command that included the same object as the GI should make the GI associative episode less prone to interference by the TI associative episode. Results confirmed that prior cuing or prompting in this manner did enable the sea lions to perform significantly better on relational commands when no cuing was given.  相似文献   

The Impact of Science Fiction Film on Student Understanding of Science     

Michael Barnett  Heather Wagner  Anne Gatling  Janice Anderson  Meredith Houle  Alan Kafka 《Journal of Science Education and Technology》2006,15(2):179-191

Researchers who have investigated the public understanding of science have argued that fictional cinema and television has proven to be particularly effective at blurring the distinction between fact and fiction. The rationale for this study lies in the notion that to teach science effectively, educators need to understand how popular culture influences their students’ perception and understanding of science. Using naturalistic research methods in a diverse middle school we found that students who watched a popular science fiction film, The Core, had a number of misunderstandings of earth science concepts when compared to students who did not watch the movie. We found that a single viewing of a science fiction film can negatively impact student ideas regarding scientific phenomena. Specifically, we found that the film leveraged the scientific authority of the main character, coupled with scientifically correct explanations of some basic earth science, to create a series of plausible, albeit unscientific, ideas that made sense to students.  相似文献   

Green Statistics     

Vic Barnett 《Teaching Statistics》2001,23(2):35-37

Environmental statistics is an exciting and rapidly growing area of statistical application. It requires complex new approaches and methods to be developed, to enable study of the crucial environmental problems we face: whether climate change, passive smoking, industrial pollution or forest fires. For the classroom, environmental statistics can bring some reality and immediacy to our teaching.  相似文献   

Keeping excitement in teaching     

Ronald D. Simpson 《Innovative Higher Education》1987,12(1):16-21

It is imperative for those of us who teach to find ways to stay renewed and refreshed over the long term. There are at least five ways through which most of us can find new energy and excitement in our teaching. One is to focus more genuinely on our students and learn more about them as persons and as colleagues- and to listen more carefully to what they say. Another is to inform them of the important objectives of a course and allow students to assume more of the responsibility for learning. A third tip is to use a greater variety of teaching methods, particularly ones that get students more actively involved in learning. Two additional ways to add excitement to teaching are to teach new courses and to plan periodic activities away from teaching. As John Gardner has recently stated so eloquently, it is our faith in human possibilities that is the generative element in such activities as leading, teaching, and guiding students.His office offers a wide range of instructional and professional services for faculty and academic administrators in the University's thirteen schools and colleges.  相似文献   

Comparing deaf and hearing college students' mental arithmetic calculations under two interference conditions     

Davis SM  Kelly RR 《American annals of the deaf》2003,148(3):213-221

Deaf and hearing college students' mean reaction times (RTs) were compared on a mental calculation task in which they had to verify the accuracy of solutions to addition and multiplication problems. The deaf students were divided into higher and lower readers. Higher deaf readers and hearing students had similar RTs and accuracy on addition problems; their RTs were greater in the voicing interference mode than in the manual tapping interference mode. The lower deaf readers showed no RT differences between the two interference modes and had consistently lower RT performance and score accuracy across the verification tasks. On the verification task for multiplication problems, all participants showed a greater RT effect for manual tapping. The lower deaf readers were significantly less accurate on multiplication problems.  相似文献   

Conditioning of the nictitating membrane response of the rabbit (Oryctolagus cuniculus) as a function of length and degree of variation of intertrial interval     

W. Ronald Salafia  Frederick W. Mis  W. Scott Terry  Robert S. Bartosiak  Anthony P. Daston 《Learning & behavior》1973,1(2):109-115

The study involved three experiments. The first, a parametric investigation of nictitating membrane conditioning with eight constant intertrial intervals (ITIs) between 5 and 120 sec, orthogonal to interstimulus intervals (ISIs) of 250 and 750 msec plus three temporal conditioning control groups, revealed that performance improved rapidly with increasing ITI but stabilized at relatively low ITI values. At 750-msec ISI, a decrement in performance was found at 60-sec ITI. Experiment II, using constant ITIs of 45–75 sec in 5-sec steps, at 750-msec ISI confirmed the trend toward a performance decrement around 60 sec, although the trend was weak and highly variable. Experiment III evaluated the differences in performance between constant and variable ITI, using three ITI values and three conditions of variation at each value. Findings were discussed in terms of differences in conditioning resulting from both length and degree of variation of ITI and some subtle effects which may emerge only when constant ITIs are used.  相似文献

Relationship of changes in student motivation to student evaluations of instruction     

George S. Howard  Ronald R. Schmeck 《Research in higher education》1979,10(4):305-315

Research has demonstrated that student evaluations of instruction are influenced by variables extraneous to the instructional procedures being evaluated. One of the most important of these is the student's motivation to take the course. The Instructional Development and Effectiveness Assessment (IDEA) system controls this variable by comparing a course evaluation to a norm group of courses having students with similar motivation. The present study examined the possibility that the IDEA procedure of having students rate their precourse motivation at theend of a course might be unacceptable, because the rating would be influenced by experiences within the course itself. The data indicated that postcourse ratings of precourse motivation do deviate somewhat from actual precourse ratings, but the deviation is not of an order of magnitude which would seriously distort the interpretation of the ratings.  相似文献   

Sex and Social Class Inequalities in Education: a re‐examination     

Ronald King 《British Journal of Sociology of Education》1987,8(3):287-303

Fifteen years ago attention was drawn to the neglect of sex differences in the sociology of education, and to ways in which social class differences in attainment could not ignore these sex differences. The original propositions concerning these differences are re‐examined and expanded in a neo‐Weberian analysis of the work‐marriage, class‐status, education complex, and considered in relation to the available empirical evidence. The alternative feminist‐Marxist approaches are found to be incompatible with the evidence of sex and social class differences in non‐capitalist societies.  相似文献   

Formula-based research incentive plans at colleges and universities     

Edgar J. Ellyson  Ronald E. Barr  Edwin R. Bailey 《Research in higher education》1982,17(3):241-248

Financial problems at colleges and universities have led many institutions to initiate extra efforts to obtain extramural funds. One such effort has been the establishment of formula-based research incentive plans. These plans generally utilize the recovery of indirect costs as the basis for allocating additional incentive funds to various areas as an encouragement to obtain additional extramural funds. Data from surveys conducted by the University of Missouri-Kansas City and Ohio University were combined with National Science Foundation reports to provide information about this relatively recent phenomena. The increasing popularity of these plans was shown in that a majority of institutions had such plans in effect during FY 1979. Analyses of the effectiveness of these plans showed no statistically significant differences between institutions with incentive plans and those without such plans, although mean federal research expenditures were approximately 20% greater at those institutions without these incentive plans. The evidence presented indicates that the receipt of federal research funds is not associated with the use of a formula-based research incentive plan.  相似文献
