There is little research regarding interventions for children with internalizing behaviors in schools, both within classrooms and in nonclassroom environments. In response to this need, a nonclassroom treatment package, consisting of (a) social skills instruction, (b) mediated self‐management, and (c) a reinforcement system, was implemented to modify the socially withdrawn behavior of 3 elementary students. The effects of this treatment package were evaluated on the school playground—during recess—by recording both the number of communicative acts and the total time spent engaged in appropriate peer play for each target student. All target students showed marked improvement in their playground, social interaction. Future research should be conducted with similar populations, using variations of the described methods in other school settings. © 2007 Wiley Periodicals, Inc. Psychol Schs 44: 779–794, 2007. 相似文献

A globalized world requires research to transcend geographical boundaries; this includes training students in international collaborative research. The purpose of this project was to identify the benefits, opportunities, and challenges of students from two universities (Kansas State Univ. and Tallin Univ. of Technology) working on an international research project together. For this purpose, six graduate students from the Center for Sensory Analysis and Consumer Behavior, Kansas State Univ., partnered with 20 Food Science major students from a Product Development class at Tallinn Univ. of Technology. Students worked together by distance in a partnership developing a rye bread sensory lexicon for systematically understanding the sensory properties of this product category, conducting Landscape analysis by using sensory mapping techniques on rye bread products from Northeast Europe for capturing the market complexity and to identify opportunity for new product development and new products concepts. Students from Kansas then went to Estonia for further meetings. After the trip, students and professors were asked for their feedback. Results showed that students identify learning food trends from another country as the main benefit of their international collaboration, followed by intercultural skills and knowledge transfer. Language and difference in time zones, as well as educational backgrounds, were identified by students as the main challenges of the collaboration. When US students were asked to rate the learning outcomes stated in the syllabus, understanding the cultural characteristics of Estonia was the one scored highest. Professors mentioned this opportunity is unique because it gives a cultural component programs usually not only an offer and a chance to develop time management skills by working across divergent time zones, but also to practice options for managing language barriers. This project shows that it is possible to setup a partnership between students across different countries and have a positive outcome that includes unique learning experiences for students; especially in terms of time and project management. 相似文献

Open textbook initiatives have appeared as an alternative to traditional publishing. These initiatives for the production of alternatively copyrighted educational resources provide a way of sharing materials through the Web. While the open model of peer‐produced materials enables the global reuse of textbooks, the combination of fragments to produce new textbooks tailored to particular needs is not easy. The heterogeneity of topics and target audiences, as well as the cultural and institutional differences of educational systems across the globe, raises the need for new compositional features, fostering—at the same time—the reuse of the newly produced combinations. This paper reviews the current models of reuse and sharing, and presents a quantitative analysis of the Connexions repository which provides evidence about the culture of reuse in open textbook initiatives. 相似文献

IntroductionTotal bilirubin tests are highly demanded in clinical laboratories. Since icteric index (I-index) has zero cost, we aimed to evaluate its clinical utility and cost-effectiveness to determine if total bilirubin is necessary to be tested. We took into account if haemolysis could interfere to icteric index determination.Material and methodsRetrospectively we reviewed I-index results in two cohorts (43,372 and 8507 non-haemolysed and haemolysed samples, respectively). All determinations were done using Alinity c chemistry analysers (Abbott Diagnostics). Receiver operating characteristic (ROC) curve was used to determine the optimal index cut-off to discriminate between normal and abnormal bilirubin concentration (20.5 µmol/L).ResultsThe ROC curve analysis suggested 21.4 µmol/L as the optimal I-index cut-off but differences in sensitivity and specificity were detected between patient derivation. For rejecting purpose, 15.4 µmol/L and 17.1 µmol/L I-index thresholds were selected based on patient derivation (inpatients and emergency room; and primary care and outpatients, respectively) with 97% sensitivity and 0.25% false negative results. Sensitivity was much lower in haemolysed samples. We selected 34.2 µmol/L I-index as threshold to detect hyperbilirubinemia with 99.7% specificity and 0.26% false positive results, independent of haemolysis. With the icteric index cut-offs proposed, we would save 66% of total bilirubin requested and analyse total bilirubin in around 2% of samples without total bilirubin requested.ConclusionsThis study supports the use of I-index to avoid bilirubin determination and to identify patients with hyperbilirubinemia. This work considers that the economic and test savings could help to increase the efficiency in clinical laboratories. 相似文献

In a paper published elsewhere (Jiménez Gómez et al. 1997), we compared research carried out on students' conceptions of force in the decade 1975-85 with later research in the period 1985-95. Only a slight progression was found in the results offered by different authors. In this contribution we analyse the research objectives of selected investigations into students' conceptions of force, their methodological characteristics and their most widely used theoretical foundations, in an attempt to explain the lack of progress made in this research line. Some suggestions are made which may help the science teaching profession to understand students' conceptions better. 相似文献

We propose the concept of cultural validity as a form of test validity in science assessment. The conceptual relevance of cultural validity is supported by evidence that culture and society shape an individual's mind and thinking. To attain cultural validity, the process of assessment development must consider how the sociocultural context in which students live influences the ways in which they make sense of science items and the ways in which they solve them. These sociocultural influences include the values, beliefs, experiences, communication patterns, teaching and learning styles, and epistemologies inherent in the students' cultural backgrounds, as well as the socioeconomic conditions prevailing in their cultural groups. We contend that current approaches to handling student diversity in assessment (e.g., adapting or translating tests, providing assessment accommodations, estimating test cultural bias) are limited and lack sociocultural perspective. We find that attaining cultural validity may conflict with current basic principles and assumptions in testing, such as item independence and standardization. We discuss the ways in which adopting cultural validity as a criterion for test validity makes it necessary to shift assessment paradigms and adopt new procedures for assessment development. © 2001 John Wiley & Sons, Inc.
