Three pigeons were trained in a three-item simultaneous same/different task. Three of six stimulus combinations were not trained (untrained set) and were tested later. Following acquisition, the
subjects were tested with novel stimuli, the untrained set, training-stimulus inversions, and object shape and color manipulations.
There was no novel-stimulus transfer—that is, no abstract-concept learning. Two pigeons showed partial transfer to untrained
pairs and good transfer to stimulus inversions, suggesting that they had learned the relationship between the stimuli. Lack
of transfer by the third pigeon suggests item-specific learning. The somewhat surprising finding of relational learning by
2 pigeons with only six training pairs suggests restricted-domain relational learning that was controlled more by color than
by shape features. Individual differences of item-specific learning by 1 pigeon and relational learning by 2 others demonstrate
that this task can be learned in different ways and that relational learning can occur in the absence of novel-stimulus transfer. 相似文献

To succeed in autonomous online learning environments, it helps to be a highly motivated, self-regulated learner. The present study explored potential differences between undergraduate (n = 87) and graduate students (n = 107) in their levels of academic motivation and self-regulation while learning online. In particular, this study provides a comparative analysis of undergraduate and graduate students' motivational beliefs (task value and self-efficacy), use of deep processing strategies (elaboration and critical thinking), and motivational engagement (procrastination and choice behaviors). As hypothesized, graduate students learning online reported higher levels of critical thinking than undergraduates. Moreover, after controlling for experiential differences, a logistic regression analysis indicated that graduate student membership was predicted by higher levels of critical thinking and lower levels of procrastination. On the other hand, undergraduate membership was predicted, somewhat paradoxically, by greater task value beliefs and greater intentions to enroll in future online courses. Implications for online instructors and suggestions for future research are discussed. 相似文献

There are few professional development courses in Australia for the rural sector concerned with climate variability, climate change and sustainable agriculture. The lack of educators with a sound technical background in climate science and its applications in agriculture prevents the delivery of courses either stand‐alone or embedded in other courses, and adversely affects the ability of graduating students to apply climate information. This paper presents evidence from a professional development climate course with 20 professional educators and consultants and results from: surveys at the training workshop; from a questionnaire 12 months post‐workshop; and a combined interview and survey two years post‐workshop. The key finding was that professional development courses specifically addressing climate are essential, while topics should include climate and weather, the impacts of climate on agricultural systems, strategic thinking and planning options available for business. A project undertaken by professionals delivering climate education helped to improve their skills and confidence to deliver other stand‐alone climate courses or to embed climate in existing courses. The paper proposes that a suitable resource manual should be ‘problem‐based’ in its design to allow for a broad range of geographic climates, and should address a wide range of agricultural enterprises including livestock production, horticulture and cropping. The authors also propose ways to introduce and integrate applied climate knowledge and skills into the wider community. Possible progress for inter‐disciplinary education and the implications from enhancing learning about climate for sustainable agriculture are discussed. 相似文献

Abstract This paper presents a narrative analysis of an elementary school student's view of his visit to an astronomy science center in South Africa. We illustrate the power of narrative in illuminating the importance of the student's perspective in understanding the conditions for learning in a museum setting. Using principles of narrative presentation, the paper describes Tlotlo's thinking throughout his participation in a school visit to the visitors' center at a radio telescope. The paper discusses six features of the visit: student misconceptions; inadequate preparation and followup; memories and imaginings; enjoyment; discussing the visit afterwards; and socioeconomic constraints on visits. These features are examined within the context of a developing country: both confirming previous research on school visits and providing new insights into how such visits can be interpreted. The significance of narrative analysis for science center educators is discussed and suggested as appropriate for current research in museums. 相似文献

Counselors encounter the needs of youth (3–17 years) in a variety of settings; however, outside of school counseling, the profession faces a lack of preparation, professional development, and research focused on mental health practice with youth. Using the Delphi method, 12 counselor educators and 15 practicing counselors were polled regarding research priorities for mental health counseling with youth. Research that considers how varying developmental stages and systems (e.g., families, schools, communities) affect the mental health of youth was identified as a priority. Implications for counselor preparation, professional development, and research are offered on the basis of these results. 相似文献

Based on the results of a generalizability study of measures of teacher knowledge for teaching mathematics developed at the National Center for Research on Evaluation, Standards, and Student Testing at the University of California, Los Angeles, this article provides evidence that teachers are better at drawing reasonable inferences about student levels of understanding from assessment information than they are at deciding the next instructional steps. We discuss the implications of the results for effective formative assessment and end with considerations of how teachers can be supported to know what to teach next. 相似文献

The benefits of bilingual education for a disadvantaged indigenous population as an investment in human capital are significant. Students of bilingual schools in Guatemala have higher attendance and promotion rates, and lower repetition and dropout rates. Bilingual students receive higher scores on all subject matters, including mastery of Spanish. The efficiency of bilingual education is confirmed by a crude cost–benefit exercise. A shift to bilingual schooling would result in considerable cost savings because of reduced repetition. The higher quality of education generating higher promotion rates will help students complete primary education and will substantially increase completion rates at low cost. The costs saving due to bilingual education is estimated at $5 million, equal to the cost of primary education for 100,000 students. 相似文献

There is sufficient evidence, drawn from surveys of innovation in the public sector and cognitive testing interviews with public sector managers, to develop a framework for measuring public sector innovation. Although many questions that are covered in the Oslo Manual guidelines for measuring innovation in the private sector can be applied with some modifications to the public sector, public sector innovation surveys need to meet policy needs that require collecting additional types of data. Policy to support public sector innovation requires data on how public sector organizations innovate and how a strategic management approach to innovation can influence the types of innovations that are developed. Both issues require innovations surveys to delve deeply into the innovation processes and strategies that are used by public sector managers. Implementation of the measurement framework proposed in this paper would open up opportunities for a new, policy-relevant research program on public sector innovation. 相似文献

As states evaluate whether they should continue with their current assessment program or adopt next-generation college readiness assessments, it is important to ascertain the degree to which current high school assessments can be used for college readiness interpretations. In this study, we examined the ability of a state assessment to serve as an indicator of college readiness. Empirical evidence is presented summarizing relationships between performance on the standards-based high school assessment and performance in college. Benchmarks were set on the Reading, Mathematics, and Science tests by linking assessment scores directly to grades in college courses. The accuracy of the benchmarks was similar to that of a traditional college admission test. Students who met the college readiness benchmarks earned higher grades in general education college courses and had higher first-year college grade point averages. Implications for states and other stakeholders are discussed. 相似文献

The Performance Assessment for Leaders (PAL) is a four-task evaluation system designed to improve the quality of initial school leaders in Massachusetts by evaluating candidate readiness using a rigorous, standard assessment system. By design, it is signalling leadership quality expectations to preparation programmes. Through two years of survey research with leadership preparation faculty (n?=?12) and candidates (n?=?53) who completed PAL, we explored faculty understanding the PAL assessment, assessment alignment task to programme content, candidate preparedness, and impact on programmes. Results show that faculty used PAL to improve their preparation programmes and provide high-quality learning experiences for candidates. 相似文献
