In three experiments, we examined the effect on the patterns of responding noted on fixed interval (FI) schedules of prior
exposure to a range of interval and ratio schedules. Rats leverpressed for food reinforcement on random ratio (RR), random
interval (RI), or variable interval (VI) schedules prior to transfer to FI schedules. In Experiment 1, prior exposure to an
RR schedule retarded the development of typical FI patterns of responding. Exposure to a yoked RI schedule produced even greater
retardation of typical FI performance. This effect was replicated in Experiment 2, using a within-subjects design. Rats responded
on a multiple RR-RI schedule prior to a multiple FI-FI schedule. Typical FI performance emerged more slowly in the component
previously associated with the RI than with that associated with the RR. In Experiment 3, exposure to an RR schedule retarded
the development of FI performance to a greater extent than did exposure to a VR schedule. The latter schedule was programmed
to allow the possibility that inhibitory control would develop after reinforcement. These results confirm that ratio schedules
independently result in the disruption of FI responding. This effect was not long lasting and cannot be used plausibly to
explain species differences in responding to FI schedules. However, it does suggest that temporal control—as manifested by
the transfer of inhibitory control from one schedule to another—could facilitate movement between interval schedules. 相似文献

Much research is available that details student experiences of immigration and adaptation to receiving countries and schools, but few studies analyze the metaphors used by immigrant students (IS) when talking about the immigration experience, or offer a comparative lens through which to view identity negotiation in two very different contexts. The present paper aims to address these gaps by conducting a comparative linguistic analysis of 20 interviews conducted with IS at universities in South Africa and the United States in order to gain a greater understanding of immigration and the types of identity negotiation processes learners undergo in these very different countries. Findings reveal interesting similarities between metaphorical conceptions of immigration across different cultural contexts and a remarkable resilience in the use of adaptation strategies and identity development that leads to salient pedagogical implications for teachers of higher education who face increasingly international classrooms. 相似文献

Despite the 1982 Plyler v. Doe decision guaranteeing education for undocumented children, access appears to be under threat as some states and localities reconsider existing policy. The basis of these attitudes should be better understood. We are unaware of research that has examined nativist sentiment as a predictor of attitudes toward education policy for children. Using data from the 2006 Immigration Survey from the Pew Hispanic Center we consider the influence of cultural and economic nativism on attitudes toward education access for immigrant children. Findings show that certain measures of both forms of nativism predict opposition to education access. 相似文献

In reviews of university teacher training, the parts of the curriculum based on educational science are often criticized as missing practical relevance and being non-cumulative. At the same time, uncertainty exists regarding which educational science based content is important for teacher candidates. The objective of the Delphi study presented here was the identification of core educational science content in university training. To this aim, a survey was carried out amongst 49 experts from different subject areas and phases of teacher training in three rounds using a standardized questionnaire. In the first round, 213 topics were specified, which were then assessed by experts regarding their importance for various aspects of the teaching profession. In the second and third rounds, which had the objective of reducing the number of topics, the experts chose a limited number of topics based on their relevance for university teacher training and for the practical success of teaching itself. The results show that the original list was comprehensive and that there is a consensus among most of the experts on their respective importance for teaching training. 相似文献

This study was undertaken to determine the suitability of the California Abbreviated WISC—Form 1 (CAW-1) for use with WISC-R subtests. Subjects were drawn from the files of previously evaluated students from two southern mountain communities. Examination of WISC records within the age and IQ ranges of the CAW-1 (CA 8-0 to 13-6, IQ 50 to 80) indicated that our sample was not significantly different from the CAW-1 noim group (N = 148, r = .85 between CAW-1 & WISC Full Scale IQ). WISC-R recods (N = 178) for the same ranges were examined and were found to be more highly predictive of Full Scale IQs (r = .91, FSIQ = .98 CAWIQ + 2.2). Extensions of the age range from 6-0 to 16-11 and of the IQ range from 40 to 100 were attempted. Final results (N = 284) indicated the CAW-1 could be used with the WISC-R over the full age range and for IQs ⩽ 100 with minor alteration (r = .96, FSIQ = 1.09 CAWIQ - 5.4). The second sample served for cross validation of these results. Using the alteration, results were consistent with original findings (N = 202, r = .93, FSIQ = .98 CAWIQ + 2.2). It was concluded that the CAW-1 was suitable for use with WISC-R subtests with minor alterations. 相似文献

There is mixed evidence as to whether concrete manipulatives (e.g., toy animals) are better than abstract manipulatives (e.g., counters) for teaching mathematical concepts to children. Concreteness is defined as the amount of extraneous information a manipulative provides, and in this study we aimed to unpick which dimensions of concreteness influence manipulative choice. Researchers, teachers, and parents completed a comparative judgment task comparing images of manipulatives varying in different dimensions of concreteness, selecting which they would choose to teach arithmetic to children. The findings indicated homogeneous, 3-dimensional manipulatives were the most preferred across all groups to teach arithmetic to children, regardless of more extraneous features. This contradicts research recommendations to minimize the use of concrete manipulatives due to their distractive qualities. Instead, it suggests that some concrete features may be preferred in more naturalistic contexts. More research is required to investigate how different dimensions of concreteness influence learning outcomes for children both in artificial research contexts and in practice. 相似文献
