The study reported on in this paper is set in the context of a national programme of professional development for primary teachers in the Republic of Ireland which has been in operation since 1999 and finished in 2008. The paper explores the acquisition and interpretation by teachers of the elements of the reform. The authors consider the extent to which the professional development experiences facilitated change in teachers’ knowledge and if the teachers interpreted this in the way expected by policy‐makers. The theoretical basis to the study draws on previous research that conceptualises teacher learning/knowledge acquisition and the change process as being dependant on an interwoven mix of factors, including teacher, school and policy‐level contexts and characteristics. To a large degree the findings of this study do not deviate wildly from this prior work, which suggests that policy‐makers and planners of CPD programmes, despite their best intentions, still need to be cognisant of such factors. 相似文献

Self-Determination Theory specifies the existence of three basic psychological needs: autonomy, competence, and relatedness. The current set of studies (a) provides a narrative review of past research on the Basic Needs Satisfaction in General Scale, (b) examines its dimensionality which has been assumed but not empirically studied, and (c) gathers external validity evidence. Confirmatory factor analysis was used to test the existence of a one- and a three-factor solution; neither model fit the data. After patterns of misfit were examined across three independent samples, a reduced, 16-item three-factor model with a negative-worded method effect was championed. External validity evidence, collected by examining the differential relationships between the three needs and measures of well-being and worry, supported the distinctiveness of the three needs. Although the results are promising, future research is needed to examine the generalizability of the psychometric properties of the modified scale. 相似文献

One of the core functions of explanation is to support prediction and generalization. However, some explanations license a broader range of predictions than others. For instance, an explanation about biology could be presented as applying to a specific case (e.g., “this bear”) or more generally across “all animals.” The current study investigated how 5‐ to 7‐year‐olds (N = 36), 11‐ to 13‐year‐olds (N = 34), and adults (N = 79) evaluate explanations at varying levels of generality in biology and physics. Findings revealed that even the youngest children preferred general explanations in biology. However, only older children and adults preferred explanation generality in physics. Findings are discussed in light of differences in our intuitions about biological and physical principles. 相似文献

There has been considerable media coverage highlighting the lack of gender diversity in Silicon Valley, stressing the relatively low participation of women in the high-tech economy. Austin offers a unique case for testing whether similar gender issues characterized other high-tech regions because the city has historically benefited from the expansion of Silicon Valley’s large high-tech firms since the 1980s. The gender-biased business practices identified in Silicon Valley firms may have been transferred to their branch plants in Austin. Our analysis shows women’s losses in middle-skill occupation employment shares were concentrated in the low-tech industry and were partially offset by job share gains in high-skill occupations in the same sector between 1980 and 2015. Men’s losses in middle-skill occupation job share were also mainly concentrated in the low-tech sector but were partially offset by employment share gains in high-skill occupations only in the high-tech industry during this period. Women made large gains in relative real median wages only in high-skill occupations in the high-tech industry while their relative real median wages in other skill occupations and in the low-tech industry stagnated around zero during this period. Men’s gains in relative median wages were also concentrated only in the high-tech industry but were less than half of women’s and were negative (between ?10 and ?21 percent) in other occupations in the high-tech industry and across all occupations in the low-tech industry. As noted in previous studies, the impact of job polarization is not well understood across sectors and gender. This study finds the high-tech industry in Austin has had unintended consequences in terms of job polarization across gender, providing relatively fewer job opportunities in high-skill occupations to women than men but offering much higher gains in relative real median wages to women than men. Males also found relatively more job opportunities in high-skill occupations in the high-tech industry than women but experienced only half of women’s gains in relative median wages in this industry between 1980 and 2015. 相似文献

This study explores the diffusion of Web 2.0 technologies among science educators and the ways that these technologies are used to build teacher professional communities of practice (CoP) in life sciences and physical sciences. We used surveys and web analytics collected over a 21-month period to examine factors that motivate teachers to collaborate in these CoPs and the extent to which collaborative participation contributes to the development of sociotechnical capital and job outcomes, such as instructional practices and self-efficacy for science instruction. Results showed that only the lack of co-located peers at teachers’ schools predicted CoP participation. Participation did not predict job outcomes, but it did predict some aspects of sociotechnical capital, such as a cohesive climate and situated knowledge. In addition, sociotechnical capital was associated with job outcomes, including use of inquiry-based instruction, use of inquiry-based classroom activities and teacher self-efficacy. The lack of effect of most of the antecedent variables in predicting participation and the relatively minor role of participation in contributing to sociotechnical capital and job outcomes may be explained by floor effects on participation due to infrequent and ephemeral engagement of CoP members. Although participation rates were generally low, the positive association of participation with sociotechnical capital as well as generally favorable ratings of sociotechnical constructs suggest that online CoPs may have value for distributed science educators. Future research should address whether persistent participation by individuals is needed to build and sustain sociotechnical capital in online CoPs and to enhance development of participants’ teaching attitudes/practices. 相似文献

AN INVESTIGATION OF CRITICAL MASS: The Role of Latino Representation in the Success of Urban Community College Students 总被引:3,自引:0,他引:3

The community college has historically functioned as a primary access point to postsecondary education for Latino students.
This study, an investigation conducted through an analysis of the Transfer and Retention of Urban Community College Students
(TRUCCS) project, focuses on Latino students enrolled in urban “minority-majority” community colleges, where Latino students
have a high representation. The specific interest of this research is the role and effect of the level of representation of
Latino community college students on their academic outcomes. The relationship between the level of representation of Latinos,
and the levels of academic success are analyzed in concert with other variables, such as, the level of representation of Latino
faculty on campus, student age, attitude, academic integration, English ability and aspiration. Findings indicate a relationship
between academic success of Latino community college students and the proportion of Latino students and faculty on campus.
The findings thus suggest that a critical mass of Latinos may be a positive influence encouraging “minority” students to higher
academic performance. 相似文献

Use of the spelling program WILT with a class of mixed-ability third-year secondary-level pupils as part of an evaluation study of programs for language development is reported. The behaviour and language activities characteristic of pupils using WILT are described and 14 categories of language activity identified. The results of an analysis of the language activities of four groups are presented, and the types of learning that are encouraged by WILT are identified. Differences between the pupils' and the class teacher's evaluations of WILT are examined, and the educational value of the program assessed. 相似文献

A recent Review of Teacher Education in Scotland reports that 23% of respondents (n = 2381) encountered variable or very poor school placement experiences. This paper uses Lave and Wenger’s ideas concerning Communities of Practice (1998) and Legitimate Peripheral Participation (1991) as analytical tools with which to understand the nature and impact of student teachers’ problematic experiences of school placement. A total of 14 Professional Graduate Diploma in Education students on a one-year Secondary English course were followed through the practice elements of their Initial Teacher Education programme and data were constructed from learning logs and semi-structured interviews. Analysis provided a nuanced account of the student teachers’ difficulties in attaining member status as Legitimate Peripheral Participants in communities of practising teachers, with the concepts ‘joint enterprise’, ‘mutual engagement’ and ‘shared repertoire’ being found to be useful in explaining these difficulties. Limitations in the theoretical framework were also discovered and these are highlighted and developed in the paper. 相似文献

Elementary school teachers often implement classroom behavioral management systems to address student misbehavior. Common problems targeted by these systems are the inattentive, hyperactive, and impulsive behaviors characteristic of attention‐deficit/hyperactivity disorder (ADHD). This study examined teachers' attributions for why children display ADHD behaviors, and how such attributions affect their experiences with children in the context of interventions to manage these behaviors. Participants were 32 preservice teachers undertaking a practicum in a summer program for 137 children (Grades 1–3), some of whom had ADHD. Teachers were trained to implement classroom‐wide behavioral management. Teachers' attributions for children's ADHD behaviors were assessed using a vignette measure, before teachers had met their students or begun training on intervention techniques. When controlling for attributions regarding oppositional behavior, teachers' initial attributions for ADHD behaviors as less internal/controllable predicted children reporting more positive relationships with that teacher during the summer program. Teachers' initial attributions for ADHD behaviors as less stable predicted teachers' greater satisfaction with the intervention techniques during the summer program and their greater attunement to children's social networks. Cognitions about the causes of children's ADHD behaviors held by preservice teachers may relate to their subsequent experiences with children in the context of implementing classroom behavioral management. 相似文献
