Most existing research on early identification of learning difficulties has examined the validity of methods for predicting future academic problems. The present study focused instead on the sensitivity of kindergarten teachers to learning problems in their students and on the continuity of teacher-identified problems over time. To identify early learning problems, kindergarten teachers in a suburban school district rated student progress toward six academic objectives as satisfactory or unsatisfactory. Twenty percent of the district's 303 kindergarten children received unsatisfactory ratings in at least one area. Thirty-eight of these children (identified group) were matched to 34 children with satisfactory ratings in all areas (nonidentified group). Results of testing conducted during kindergarten revealed poorer academic achievement in identified children than in nonidentified children. Children from the identified group also performed more poorly than children from the nonidentified group on tests of phonological processing and working memory/executive function and were rated by teachers as having more behavior and attention problems and lower social competence. Follow-up of the sample to first grade documented continued learning problems in the identified group. These findings support the use of teacher judgements in early detection of learning problems and argue against reliance on discrepancy criteria.  相似文献

‘Ability’ or attainment grouping can introduce an additional label that influences teachers’ expectations of students in specific attainment groups. This paper is based on a survey of 597 teachers across 82 schools and 34 teacher interviews in 10 schools undertaken as part of a large-scale mixed-methods study in England. The paper focuses on English and mathematics teachers’ expectations of secondary school students in lower attainment groups, and explores how low-attaining students are constructed as learners who benefit from specific approaches to learning justified through discourses of nurturing and protection. The authors argue that the adoption of different pedagogical approaches for groups of low-attaining learners to nurture them may in some cases be fostering dependency on teachers and cap opportunities for more independent learning. Furthermore, more inclusive whole-school learning-culture approaches may better allow for students across the attainment range to become independent learners.  相似文献

Mentors and Muses: New Strategies for Academic Success   总被引:2,自引:0,他引:2  
Mentoring programs in higher education institutions have met with mixed success. In response to the limitations inherent in the dominant approaches to mentoring, we present an example of a unusual mentoring program, the New Scholars Network (NSN). The NSN is a variant of traditional mentoring approaches, having evolved from mentoring into musing. Framed within a radical humanist philosophy, musing is a process of creating peer communities that facilitates connections between naturally developing relationships, shared power, and collective action. Through mentoring as musing new faculty have the potential to evolve as change agents in the institution, instead of assimilating into the existing system.  相似文献

In three between-groups blocking experiments with rats, two concurrent and one forward, several common control procedures were employed: Reinforced trials with the putative blocking stimulus were either omitted entirely (Kamin control), replaced by unsignaled reinforcements (Wagner control), or replaced by reinforced trials with a different stimulus (C1 control). In each experiment, parallel treatments with the target stimulus absent during training served to examine the possibility that differential responding in tests with the target stimulus might be traced solely to differential exposure to the nontarget stimuli. In Experiment 1, responding by a concurrent blocking group during the test was no different than responding by a Kamin control group, and responding by a Wagner control group was greater than that of either of the other groups—a pattern of results, mirrored in the performance of the target-absent groups, that could be attributed to the elevation of contextual excitation by unsignaled reinforcement. In Experiment 2, responding in the test by a concurrent blocking group was no different than that by a C1 control group. In Experiment 3, a finding of less responding by a forward blocking group than by a C1 control group when the target stimulus was present during training, but not when it was absent, provided plausible evidence of blocking.  相似文献

Abstract

It is important to understand how people experience pleasure and sexual satisfaction with a partner, as these phenomena can impact how they view their relationships, themselves, as well as the role of sexual activities within relationships. Three hundred and four undergraduates at East Carolina University and California State University Chico who reported having at least one sexual experience with a partner completed a 45 item survey assessing social correlates of sexual pleasure and sexual satisfaction. Analysis revealed that those in a committed relationship reported the highest sexual pleasure (on average), followed by those in an emotionally-involved relationship, followed by those in a hookup. A parallel analysis for sexual satisfaction revealed the same associations. Regarding the length of relationship, being in a relationship for at least six weeks appeared to matter for pleasure and satisfaction, but being in a relationship longer than six months did not indicate greater advantages than those in a relationship between six weeks and six months. Limitations of the research are identified.  相似文献

Electronic piracy is perceived as a growing threat to the publishing industry. This article looks at the technology of copyright infringement and the channels for distribution of infringing electronic copies. It considers the English legal framework for dealing with electronic piracy, and the practical steps that publishers can take to reduce the risks of piracy.  相似文献

Although most institutions seem to have in place a formal mechanism for evaluating faculty activities annually for the purpose of merit and promotion, a post-tenure review process is relatively new. Faculty facing a post-tenure review, which calls for both a backward review of what has been accomplished over a multi-year period and a forward projection of what is planned, may not have sufficient guides to know what to include and what to omit. As a result of my exposure to the American Association for Higher Education's (AAHE) Peer Review of Teaching Project I tried to adapt one of their strategies to provide the backward and forward view for my post-tenure review. The strategy was the reflective memo; and it proved to be adaptable as a guide in the review of research, teaching, and service. I hope the process that I describe and the lessons that I learned will be helpful to others facing a similar process.  相似文献

The current study examined how adolescents' ethnic‐racial identity (ERI) informed the demographic diversity of their friendship network (Goal 1) and the extent of similarity between adolescents' and their friends' ERI (Goal 2). Participants were sixth and seventh grade students (= 353; Mage = 11.88, SD = .73; 50% girls; 29% African American, 31% White, 13% Latino) in the Midwestern U.S. Results from longitudinal cross‐lagged models (Goal 1) indicated that having more diverse friendships at T2 was associated with greater T3 ERI exploration among all youth. In addition, boys who reported higher ERI resolution at T1 had more diverse friendships at T2. Furthermore, findings from longitudinal social network analyses (SNA; Goal 2) suggested that influence drove similarity between adolescents and their friends in ERI exploration and resolution.  相似文献
