Squirrel monkeys (Saimiri sciureus) were trained on visual recognition memory tasks in a Wisconsin General Testing Apparatus with a trial-unique procedure that used 250 objects as stimuli. In Experiment 1, acquisition of a trial-unique delayed non-match-to-sample task (DNMS) was compared with acquisition of a trial-unique delayed match-to-sample (DMS) task. The DNMS task was learned in significantly fewer trials and with significantly fewer errors. Two animals in the DNMS group demonstrated highly accurate retention of the DNMS strategy despite an 11-month hiatus in experimental testing. In Experiment 2, the same procedures were used to study the learning of lists of 3, 5, 10, or 20 serially presented items. Although the animals were able to accurately remember lists of up to 20 items, there was no evidence of serial position effects. 相似文献
The objective of this research is to identify the relationship between formal learning spaces and student learning outcomes. Using a quasi‐experimental design, researchers partnered with an instructor who taught identical sections of the same course in two radically different formal learning environments to isolate the impact of the physical environment on student learning. The results of the study reveal that, holding all factors excepting the learning spaces constant, students taking the course in a technologically enhanced environment conducive to active learning techniques outperformed their peers who were taking the same course in a more traditional classroom setting. The evidence suggests strongly that technologically enhanced learning environments, independent of all other factors, have a significant and positive impact on student learning. 相似文献
To date, few observational studies have addressed Scandinavian school inspectors in the field, specifically how inspectors use templates to monitor the formative assessment routines of schools and local school authorities. This paper investigates how the current inspection handbook is being adopted and enacted on the municipal level and the school level in Norwegian compulsory schools. Specifically, this study illuminates through observation two empirical examples of how one of the 17 County Governors’ Offices, as part of a larger study, conducted regular, state school inspection. Conceptually, the paper focuses on how inspection guides and steers though use of fixed templates. Analysis shows that inspectors and schools under scrutiny are struggling in combining the traditional focus on legal compliance with a more performative emphasis on formative assessment of students. In addition, the examples given highlight how combining field observation and the concept of “governing by templates” contributes to school inspection studies, in a dynamic policy context undergoing substantial change. 相似文献
To identify the incidence of self-reported physical and sexual child abuse among homeless youth, the self-perceived effects of past abuse, and current interest in treatment for past abuse among homeless youth with histories of abuse.
Methods
Homeless and street-involved persons aged 18-23 filled out a questionnaire and participated in a structured assessment of histories of abuse, tobacco use and substance abuse.
Results
Sixty-four homeless youth in Salt Lake City, Utah completed the study, 43 males and 21 females. Eighty-four percent screened positive for childhood physical and/or sexual abuse occurring before the age of 18; 42% screened positive for both physical and sexual abuse; 72% reported still being affected by their abuse. Among all abuse victims, 44% were interested in treatment for their abuse history and 62% of homeless youth who reported still being affected by their abuse were interested in treatment. Individuals were more likely to be interested in treatment if they were female, had not completed high school or had been previously asked about family dysfunction. Many victims who declined treatment offered spontaneous insight into their decision. Interest in treatment was similar to interest in treatment for other behaviors such as smoking and substance abuse.
Conclusions
Histories of abuse are common among homeless youth. A majority of those reporting a history of abuse are still affected by their abuse. Interest in treatment for a history of abuse was comparable to interest in treatment for other morbidities in the homeless youth population such as tobacco use and substance abuse. Our finding that homeless youth continue to be impacted by their abuse and are interested in treatment should prompt more screening for histories of abuse. 相似文献
A Lamaze Certified Childbirth Educator and labor-support doula who provides services in two major, metropolitan areas shares her reactions and education experiences in dealing with the findings of Listening to Mothers II. She found that her first response to the survey findings involved assisting a community-wide effort to raise the awareness of women about their childbirth options, with a special emphasis on providers who practice in adherence to The Coalition for Improving Maternity Service's Mother-Friendly Childbirth Initiative. In addition, she added a component to her classes to help her students proactively explore why so few women feel they can assert their rights to refuse unnecessary interventions during childbirth. 相似文献
Background: computer software is widely used to support literacy learning. There are few randomised trials to support its effectiveness. Therefore, there is an urgent need to rigorously evaluate computer software that supports literacy learning.
Methods: we undertook a pragmatic randomised controlled trial among pupils aged 11–12 within a single state comprehensive school in the North of England. The pupils were randomised to receive 10 hours of literacy learning delivered via laptop computers or to act as controls. Both groups received normal literacy learning. A pre‐test and two post‐tests were given in spelling and literacy. The main pre‐defined outcome was improvements in spelling scores.
Results: 155 pupils were randomly allocated, 77 to the ICT group and 78 to control. Four pupils left the school before post‐testing and 25 pupils did not have both pre‐ and post‐test data. Therefore, 63 and 67 pupils were included in the main analysis for the ICT and control groups respectively. After adjusting for pre‐test scores there was a slight increase in spelling scores, associated with the ICT intervention, but this was not statistically significant (0.954, 95% confidence interval (CI) – 1.83 to 3.74, p = 0.50). For reading scores there was a statistically significant decrease associated with the ICT intervention (?2.33, 95% CI ?0.96 to ?3.71, p = 0.001).
Conclusions: we found no evidence of a statistically significant benefit on spelling outcomes using a computer program for literacy learning. For reading there seemed to be a reduction in reading scores associated with the use of the program. All new literacy software needs to be tested in a rigorous trial before it is used routinely in schools. 相似文献
Four experiments compared runway extinction or hurdle-jumping from nonreward performance following brief (10 trials) continuous or partial reinforcement acquisition. Some of the partial groups received all nonrewarded trials prior to any rewards. The major findings were that (l) rats receiving all nonrewarded experiences prior to rewarded ones were more persistent during extinction than continuously rewarded subjects; (2) rats receiving nonrewarded placements prior to rewarded ones in one compartment of a two-compartment box, failed to learn a hurdle-jumping response to escape nonreward, whereas rats not receiving the initial nonrewards did learn the escape response; (3) increasing the number of rewarded placements following initial nonrewarded ones offset the effect noted in (2). The results, which are discussed in the context of a frustration analysis of the small-trials partial reinforcement effect, suggest that incentive growth over rewarded trials is retarded when the rewards have been preceded by nonrewards. The similarity of these results to those investigating the phenomenon of latent inhibition is apparent, and possible mechanisms responsible for the present results are suggested in current theoretical accounts of latent inhibition. 相似文献
