Pigeons' keypecking was reinforced by food on baseline schedules of multiple variable interval (VI) x VI x and on contrast schedules of multiple VI x VI y. Deprivation of food was varied by maintaining subjects at 75%, 85%, and 95% (+/- 2%) of their free-feeding weights. Positive and negative behavioral contrast were observed. The size of the contrast was not systematically altered by changes in deprivation. Positive and negative contrast were both larger later in the session than they were earlier. Within-session decreases in responding were steeper for the baseline than for the contrast schedules for positive contrast. Within-session decreases were steeper for the contrast than for the baseline schedules for negative contrast. These results were predicted by the idea that different amounts of habituation to the reinforcer during the baseline and contrast schedules contribute to behavioral contrast. The results show that contrast occurs under conditions that reduce the effect of the following component. The results support the assumption that positive and negative contrast are produced by symmetrical theoretical variables.  相似文献

The association between child maltreatment (CM) and educational outcomes have been well documented. However, there is a paucity of research that explores the association between different types of maltreatment and other school problems that may affect the educational outcomes of maltreated children. This study examined the association between different types of CM and school changes, concentration problems, and special educational needs. Gender differences were also examined. Structured interviews were conducted with 2,980 participants. Significant associations emerged between CM, in particular, multiple maltreatment experiences and school problems. Males had higher concentration difficulties and special educational needs. More research attention is needed into optimal learning environments and interventions that support maltreated children more effectively.  相似文献

This study investigated the hypothesis that prompting students to self-assess their interest and understanding of science concepts and activities would increase their motivation in science classes. Students were randomly assigned to an experimental condition that wrote self-assessments of their competence and interest in science lessons or a control condition that wrote summaries of those same lessons. Writing activities were 10?min long and were given approximately once a week for eighteen weeks. Student motivation was assessed via self-report surveys for achievement goals and interest in science before and after the intervention. Students in the experimental condition showed higher endorsement of mastery goals and reported greater situational interest in science topics after the intervention compared to students who summarised the lessons. Increases in situational interest predicted higher individual interest in the domain. Results indicate an instructional practice requiring just 3?hours out of a semester of instruction was sufficient to achieve these effects on motivation in science classes.  相似文献

With the advent of the Next Generation Science Standards in engineering (NGSS, 2013), teachers of multiple subject areas are being asked to do more than ever before—not only to teach engineering content in the K-12 classroom but also to engage students in authentic disciplinary reading and writing as part of content learning. These standards sound good, but they beg several questions; namely, what do we know about how, why, and when do engineers read and write as they do their work every day? What do teachers charged with engineering education know about the daily practices of engineers, let alone the literacy practices? In short, little is known about the literacy practices of engineers in the course of their daily work. This article draws on participant observation, interviews, and document analysis of one research engineering laboratory to illustrate the literacy practices of one group of engineers and begins to draw implications from this work for teacher practice in achieving the NGSS engineering education standards.  相似文献

The purpose of this study was to review and analyze effective classroom reading practices for early graders, using information gathered from the existing content-general and content-specific observation protocols measuring teachers’ classroom reading practices. Dimensions and constructs from 28 observation studies were synthesized to identify classroom instructional practices that have positive impacts on student achievement. Findings revealed that (a) instructional support, emotional support, and classroom management have positive impacts on student achievement, (b) the degree to which instructional practices are effective depends on students’ particular learning needs, and (c) students’ entering skills and primary language are associated with instructional effectiveness in reading. Challenges and implications for future research on effective instructional strategies for special education and the development of an observational protocol for special education teacher effectiveness are discussed.  相似文献

This paper seeks to elucidate a specific type of charter school. While much has been written about school choice and the expanding charter school segment, a growing and important number of charter schools do not fit in to the common understanding of these schools. Distinct from many of their counterparts, prestige charter schools have the following two features: elements which foster a reputation similar to that of elite private schools and a student population demographically distinct from local public district schools – whereby the prestige charters serve a disproportionate number of advantaged families. The prestige elements include: founding by advantaged community members; parental involvement; wait lists; popularity with advantaged professionals; high test scores; and niche themes. The authors will show through two in-depth case studies that prestige charter schools work hand-in-hand with gentrification in urban neighborhoods, and result in racial and class segregation and inequality. This paper examines how these charter schools struggle when a rise in prestige coincides with a decline in access for low-income students. The authors recommend that given the current system of school choice, prestige charter schools must use tools and mechanisms to maintain demographic diversity and educational equity which is in the best interest of all children.  相似文献

The role of the principal is imperative in creating a school climate that nurtures differences and equality at the same time. Policy and legislation in Ireland dictates the responsibility of school principals in preventing and intervening in issues relating to bullying. The current research investigates the extent to which principals consider the impact of bullying on their students and the strategies they take to combat it in their schools. We consider how principals respond to bullying and what supports they feel are missing for them to adhere to relevant policy. A sample of 918 principals from a range of schools across Ireland completed an online survey. The results demonstrated some positive actions by principals such as the provision of anti-bullying policies. However, they also document areas that need more action such as increased access to counsellors and appointing a specific staff member to deal with and tackle bullying in each school. Guidance from the Department of Education and Skills in Ireland on the development and provision of an anti-bullying programme is called for. Results are discussed in light of the current Anti-Bullying Procedures established by the Department of Education and Skills and the Action Plan for Bullying 2013.  相似文献

Abstract

The issue of who should be included and recognised as professionals in the early childhood education and care (ECEC) service system is both contested and pressing in the current policy climate. At stake is a high-quality early childhood care and education service system that is both responsive and appropriate to the constituency it serves. A review of the history of ECEC professionalism reveals complex entanglements and debates regarding professional belonging. Services that deliver education and care to children and families living in high poverty contexts are often excluded from ECEC professionalism debates. Drawing on notions of rationality, emotionality and criticality presented in recent accounts of ECEC professionalism, we use data collected from interviews with service providers delivering services to children and families living in high poverty contexts in Australia to develop an account of criticality that is pertinent to current funding and policy contexts. We argue that these service providers’ perspectives about their own professionalism have much to offer broader debates.  相似文献

Educators are currently attempting to integrate computers into the classroom, in order to humanize their use. The strategies that have been adopted, however, are primarily logistical and ignore the philosophy that underpins this technology. It is argued in this paper that educational technology will not be humanized until it is understood to be sustained by a philosophy other than technological rationality, and thus is provided with a human base. The life-world (Lebenswelt) is identified as a proper foundation for technology, because technological rationality is illustrated to be a modality of human expression. When this is the case, technology is placed in the service of humankind, for it cannot be conceived as the genesis of personal freedom.
Zusammenfassung Gegenwärtig sind Pädagogen um die Integration von Computern ins Klassenzimmer bemüht, um deren Gebrauch zu humanisieren. Die dabei angewandten Strategien sind jedoch primär logistisch und ignorieren die theoretischen Voraussetzungen, auf die sich diese Technologie stützt. In diesem Bericht wird argumentiert, daß die Bildungstechnologie so lange nicht humanisiert wird, bis sie nicht in einem anderen Sinn als dem der technologischen Rationalität verbunden wird und auf eine humane Grundlage gestellt ist. Die Lebenswelt wird als ein wahres Fundament der Technologie identifiziert, da technologische Rationalität als eine Modalität menschlichen Ausdrucks dargestellt wird. Wenn dies der Fall ist, wird die Technologie in den Dienst der Menschheit gestellt, da sie nicht als Nemesis persönlicher Freiheit angesehen werden kann.

Résumé Les pédagogues, aujourd'hui, tentent de faire entrer l'ordinateur dans la salle de classe, afin de ramener son utilisation à l'échelle humaine. Cependant, les stratégies adoptées demeurent de l'ordre de la logistique et ignore tout de la philosophie qui étaye cette technologie. Dans cet article, il est argué que l'on ne saurait humaniser la technologie au sein de l'enseignement, tant qu'il n'est pas entendu qu'une philosophie autre que la rationalité technologique la sous-tend, la dotant ainsi d'un fondement humain; l'environnement naturel (Lebenswelt) constitue la véritable base de la technologie car la rationalité ne représente qu'une modalité de l'expression humaine. Dans ce cas, la technologie est placée au service de l'humanité et ne saurait être conçue comme sanction de la liberté individuelle.
