The object of this article is to demonstrate that the widely disseminated program LISREL 8 can be used to carry out principal component analyses. LISREL 8 offers a number of useful possibilities including multigroup principal component analysis and principal component regression. Several illustrative analyses are reported.  相似文献

Linking schools with sexual health clinics facilitates clinic access by young people. This paper documents the process of developing one such link and its impact on clinic use. Multiple data collection strategies were used to document a developing school/clinic relationship and constant comparative analysis was used to develop hypotheses from the data as follows: ” A few teachers have a good knowledge of local sexual health services and extensive experience of referring to them. ” Most tutors (despite their pastoral role) have little knowledge of local sexual health services and no experience of referring to them. ” Organising work in the school is difficult because teachers have little non-teaching time and a variable commitment to sex and relationship education. ” The link between the clinic and the school has facilitated access to the clinic by school pupils. ” Outreach work is more effective when young people meet the outreach worker repeatedly in different settings. Each hypothesis is presented with its supporting data. This information is consistent with what is known about the benefits of school/clinic links and adds to what is known about the process of developing and maintaining such links.  相似文献

Discipline-based education research (DBER) is an emergent, interdisciplinary field of scholarship aimed at understanding and improving discipline-specific teaching and learning. The number of DBER faculty members in science, technology, engineering, and mathematics (STEM) departments has grown rapidly in recent years. Because the interdisciplinary nature of DBER involves social science, senior STEM faculty members may find it challenging to evaluate the quality or impact of DBER scholarship. This essay aims to address this issue by providing guidance on evaluating the scholarly accomplishments of DBER faculty members in a way that is useful to departmental colleagues and administrators during the tenure and promotion evaluation process.  相似文献

The Course-Based Undergraduate Research Experiences Network (CUREnet) was initiated in 2012 with funding from the National Science Foundation program for Research Coordination Networks in Undergraduate Biology Education. CUREnet aims to address topics, problems, and opportunities inherent to integrating research experiences into undergraduate courses. During CUREnet meetings and discussions, it became apparent that there is need for a clear definition of what constitutes a CURE and systematic exploration of what makes CUREs meaningful in terms of student learning. Thus, we assembled a small working group of people with expertise in CURE instruction and assessment to: 1) draft an operational definition of a CURE, with the aim of defining what makes a laboratory course or project a “research experience”; 2) summarize research on CUREs, as well as findings from studies of undergraduate research internships that would be useful for thinking about how students are influenced by participating in CUREs; and 3) identify areas of greatest need with respect to CURE assessment, and directions for future research on and evaluation of CUREs. This report summarizes the outcomes and recommendations of this meeting.

Measurement bias can be detected using structural equation modeling (SEM), by testing measurement invariance with multigroup factor analysis (Jöreskog, 1971;Meredith, 1993;Sörbom, 1974) MIMIC modeling (Muthén, 1989) or restricted factor analysis (Oort, 1992,1998). In educational research, data often have a nested, multilevel structure, for example when data are collected from children in classrooms. Multilevel structures might complicate measurement bias research. In 2-level data, the potentially “biasing trait” or “violator” can be a Level 1 variable (e.g., pupil sex), or a Level 2 variable (e.g., teacher sex). One can also test measurement invariance with respect to the clustering variable (e.g., classroom). This article provides a stepwise approach for the detection of measurement bias with respect to these 3 types of violators. This approach works from Level 1 upward, so the final model accounts for all bias and substantive findings at both levels. The 5 proposed steps are illustrated with data of teacher–child relationships.  相似文献

This paper presents a systematic review of published data on the performance of sub-Saharan Africans on Raven's Progressive Matrices. The specific goals were to estimate the average level of performance, to study the Flynn Effect in African samples, and to examine the psychometric meaning of Raven's test scores as measures of general intelligence. Convergent validity of the Raven's tests is found to be relatively poor, although reliability and predictive validity are comparable to western samples. Factor analyses indicate that the Raven's tests are relatively weak indicators of general intelligence among Africans, and often measure additional factors, besides general intelligence. The degree to which Raven's scores of Africans reflect levels of general intelligence is unknown. Average IQ of Africans is approximately 80 when compared to US norms. Raven's scores among African adults have shown secular increases over the years. It is concluded that the Flynn Effect has yet to take hold in sub-Saharan Africa.  相似文献

Background:?Unlike the rest of the UK, Northern Ireland has only recently (2003) implemented legislation regarding the requirement for anti-bullying policies in the province's school system.

Purpose:?The purpose of the study was to ascertain the nature of the management of bully/victim problems across Northern Ireland schools prior to the enactment of legislation.

Sample:?From an exhaustive sampling frame of all 1329 schools in Northern Ireland (96 nursery, 910 primary, 167 secondary, 73 grammar, 54 special, 29 further education), a total of 285 schools replied to a questionnaire (20 nursery, 181 primary, 41 secondary, 26 grammar, 13 special, 3 further education, 1 non-specified), a return rate of 23.11%.

Design and methods:?A review of the literature and consultation with educational experts in Northern Ireland resulted in the development of an ‘Audit’ questionnaire designed to examine dissemination and implementation (or not) of Department of Education, or bespoke, discipline and anti-bullying policies; components of anti-bullying programmes; the communication of anti-bullying policies to the school community; staff training; reporting and management of claims of staff victimisation; sanctions against bullies; and homophobic bullying.

Results:?It was found that, in a legislative vacuum, the schools in Northern Ireland had been acting in a proactive manner regarding the management of such bully/victim problems (e.g., development and implementation of policies, effective communication strategies).

Conclusions:?These results provide a baseline from which the efficacy of subsequent legislation in Northern Ireland can be evaluated. Utilisation of the methodology adopted in this study would be beneficial in other jurisdictions in evaluations of knowledge, attitudes and management of bully/victim problems, either pre- or post-implementation of legislation.  相似文献

Teaching education is Ireland is currently undergoing significant structural and conceptual changes. School placement is at the centre of these reforms. This article reports the findings of an all-Ireland study which investigates student teachers’ experiences of teaching geography during their school placements. Based on data collected from surveys and focus group interviews with one cohort of B.Ed. students, this study illustrates the emotional journey of school placement, emerging identities as teacher, the positive impact of initial teacher education, the problematic nature of messages from ‘third parties’ and conflicting conceptualisations of geography. The findings of this study are important for student teachers and teacher educators as they illustrate the complexity of school placement and the importance of emotional as well as cognitive engagement.  相似文献
