This article describes the effects of an analysis-of-practice professional development (PD) program on elementary school students' (Grades 4–6) science outcomes. The study design was a cluster-randomized trial with an analysis sample of 77 schools, 144 teachers and 2,823 students. Forty-two schools were randomly assigned to treatment, (88.5 hours) of integrated analysis-of-practice and content deepening PD (over the course of one year) while 35 schools were randomly assigned to receive an equal number of PD hours in science content deepening alone. Students' content knowledge, as measured by a project-specific test, was compared across treatment groups. The effect size for this comparison was 0.52 standard deviations in favor of students whose teachers participated in the PD that included analysis-of-practice. This effect compares favorably to that of other elementary school interventions whose effectiveness was studied with a narrowly focused outcome measure. Analysis of the demographics of the study schools suggests that the treatment effect could be relevant outside the local study context. Implications for future research include tests of mediation for teacher-level outcomes and efficacy tests of specific teaching strategies (intervention subcomponents).  相似文献

ABSTRACT

While the ‘action’ portion of a Participatory Action Research (PAR) project is a crucial component of the process, action tends to be challenging to define, achieve, and measure. The current paper both defines and describes action within the context of a particular PAR collaboration and explores the process and challenges of navigating and implementing action in a PAR project. The specific PAR project detailed in this paper was executed within a higher education setting and involves a group of undergraduate women co-researchers studying their experiences in STEM (Science, Technology, Engineering, and Mathematics) fields.  相似文献

This study identified decision-making profiles of students who make a choice of a major in higher education. These profiles were examined in a sample of Belgian students at the end of Grade 12, when the educational system expects that these adolescents choose a specific major. Using latent class cluster analysis on adolescents’ scores for coping with career decisional tasks (i.e., orientation, exploration, decisional status, and commitment), four clusters were identified. As expected, these profiles paralleled Marcia’s (1966) identity statuses (i.e., the achievement, moratorium, foreclosure, and diffusion status). Results provided support for the external validity of the identified clusters through differential associations with several person variables (i.e., career decision-making self-efficacy, career choice anxiety, and decision-making style) and with academic functioning in higher education (i.e., commitment, academic and social adjustment). Implications for current educational research and research on career decision-making are discussed.  相似文献

Environmental degradation is a general problem but it is often more serious in developing nations where levels of awareness are lower than in industrialized countries. There is, therefore, a need particularly in developing countries to increase pro-environmental attitudes and behaviors. In this paper, we report the results of a quasi-experimental study designed to change environmental attitudes and environmental behaviors among 263 science pre-service teachers. The treatment consisted in the form of a green chemistry curriculum. We found statistically reliable changes in environmental attitudes, as measured by the New Ecological Paradigm, and in eight self-reported environmental behaviors. The Bayesian t-test suggests that the evidence for the changes to have been the result of the green chemistry curriculum is decisive. We conclude that the green chemistry curriculum constitutes a suitable context: (a) for supporting pre-service teachers in their development of pro-environmental attitudes and (b) for changing the levels of self-reported pro-environmental actions.  相似文献

This study examined whether the candidate-controlled public relations tools of political ads and candidate blogs were successful in influencing the issue and news agenda of the major television news networks during the 2004 presidential election. Data showed strong correlations between blogs and the media agenda. Advertisements did not correlate with the media agenda. Cross-lag analyses showed that the media set the candidates' agenda. The authors suggest intermedia agenda setting occurred as the media transferred their agenda to campaign blogs.  相似文献

Teachers often have difficulty implementing inquiry‐based activities, leading to the arousal of negative emotions. In this multicase study of beginning physics teachers in Australia, we were interested in the extent to which their expectations were realized and how their classroom experiences while implementing extended experimental investigations (EEIs) produced emotional states that mediated their teaching practices. Against rhetoric of fear expressed by their senior colleagues, three of the four teachers were surprised by the positive outcomes from their supervision of EEIs for the first time. Two of these teachers experienced high intensity positive emotions in response to their students' success. When student actions/outcomes did not meet their teachers' expectations, frustration, anger, and disappointment were experienced by the teachers, as predicted by a sociological theory of human emotions (Turner, J. H. (2007). Human emotions: A sociological theory. London, England: Routledge). Over the course of the EEI projects, the teachers' practices changed along with their emotional states and their students' achievements. We account for similarities and differences in the teachers' emotional experiences in terms of context, prior experience, and expectations. The findings from this study provide insights into effective supervision practices that can be used to inform new and experienced teachers alike. © 2012 Wiley Periodicals, Inc.
