This paper illustrates a new way of working collaboratively on the development of a methodology for studying teacher agency for social justice. Increasing emphasis of impact on change as a purpose of social research raises questions about appropriate research designs. Large-scale quantitative research framed within externally set parameters has often been criticised for its limited potential for capturing the contexts and impacting change, while smaller, locally embedded, mostly qualitative inquiries have been questioned on the grounds of their limited generalizability and sometimes compromising research rigour. New ways of working collaboratively are increasingly explored as a way of reconciling research rigour and impact. The paper presents the procedures for designing a study that is both methodologically rigorous and potentially impactful. Twelve researchers, practitioners and policy-makers in Scotland were extensively involved in designing a mixed-method study of teacher agency for social justice. The Critical Communicative Methodology was employed to establish egalitarian dialogue between researchers and practitioners. The procedures and the resulting research tools can be used in future studies, including large-scale quantitative analysis. The paper discusses the challenges of ownership, choice of methods, and knowledge transfer, that need to be addressed in these ways of working. 相似文献

This study investigated the cognitive processes involved in learning information presented in multimedia and text format using electroencephalographic (EEG) measures. Thirty-eight students (19 gifted, and 19 average) learned material presented with text (text); text, sound, and picture (picture); and text, sound and video (video), while their EEG was recorded. Alpha power, which is inversely related to mental effort, was analyzed. For thetext presentation, the alpha power measures showed higher amplitudes (less mental activity) over the occipital and temporal lobes, and less alpha power (higher mental activity) over the frontal lobes. The results support the assumption that thevideo andpicture presentations induced visualization strategies, whereas thetext presentation mainly generated processes related to verbal processing. The results further showed that gifted students displayed less mental activity during all three formats of presentation. These differences were especially pronounced for thevideo format. No gender-related differences in EEG patterns related to the format of presentation were observed. 相似文献

ABSTRACTModel-based instruction offers numerous benefits to students, including increased content knowledge and critical thinking. This study explored the differences in the knowledge outcomes and reasoning processes employed by undergraduate students in an introductory biology lab as they constructed, revised, and simulated a computational model of a prokaryotic gene regulatory system. We analysed post-lesson conceptual models (n?=?335) and audio-recorded small group discussions (n?=?10) of students that either constructed and revised a computational model and then investigated a pre-constructed computational model or only investigated a pre-constructed computational model to determine the impact of constructing and revising a computational model. No significant differences were found between the mental models of students who constructed and revised a computational model and those who only simulated a pre-constructed computational model. However, this study demonstrated that constructing and revising a model before simulating it offered additional benefits to students by fostering deeper cognitive reasoning processes. Constructing and revising a model elicited more explanatory and evaluative reasoning and prompted students to discuss the underlying mechanisms of the biological system. 相似文献

In adolescence, both identity concerns and feelings of loneliness are of utmost importance to the experiences of young people. Yet, a theoretically grounded hypothesis that identity and loneliness are developmentally related has never been tested. Thus, the aim of this study was to disentangle the longitudinal associations between identity processes in educational and interpersonal domains and loneliness in adolescence. The sample consisted of 632 Lithuanian adolescents (53.2% girls; Mage = 14.32; SDage = 1.09) participating in a four-wave study with 6-month intervals between assessments. Cross-lagged analyses revealed reciprocal associations between identity processes and loneliness in the educational domain and unidirectional effects of adolescents' reconsideration of commitment on loneliness in the interpersonal domain. 相似文献

The aim of this study was to investigate changes in physical activity across pregnancy and the relationship between trimester-specific physical activity and unplanned caesarean sections (CSs). A cohort study design was carried out. A cohort of 150 pregnant women was established when they received prenatal care at 29–40 weeks of gestation at a medical centre in northern Taiwan. Participants were asked to recall the amounts of physical activity in which they had engaged in the three trimesters as assessed by the Pregnancy Physical Activity Questionnaire (PPAQ). Overall self-reported physical activity for the cohort decreased by 31% in the first trimester compared to the pre-gravid period, then increased in the second trimester and remained stable until delivery. A repeated measures analysis of variance was used to evaluate the data and revealed significantly more physical activity during the second trimester than in the first and third trimesters (F = 36.471, P = 0.000). In addition, there was a significant difference between normal spontaneous delivery and unplanned CS groups (F = 4.770, P = 0.031). Logistic regression determined that the odds ratio of undergoing a CS increased by 0.644 (95% confidence interval: 0.429–0.968) for women in the third trimester who performed low levels of physical activity. Results support the benefits of physical activity, and professionals are encouraged to provide pregnant women with information on recommendations for physical activity, particularly in terms of reducing unplanned CSs. 相似文献

In libraries,full text ejournal packages are among themost unique aspects of the digital revolution.They challengemany of the basic concepts that librarians have held close totheir hearts:The journals themselves come in packages-thatis,unlike their print counter parts,they are bought as apackage and not one at a time.Many librarians who havelooked with pride at their journal collections because theywere selected one-by-one,on the basis of local needs, 相似文献

Research and policy documents increasingly advocate for incorporating engineering design into K-12 classrooms in order to accomplish two goals: (1) provide an opportunity to engage with science content in a motivating real-world context; and (2) introduce students to the field of engineering. The present study uses multiple qualitative data sources (i.e., interviews, artifact analysis) in order to examine the ways in which engaging in engineering design can support students in participating in engineering practices and applying math and science knowledge. This study suggests that students better understand and value those aspects of engineering design that are more qualitative (i.e., interviewing users, generating multiple possible solutions) than the more quantitative aspects of design which create opportunities for students to integrate traditional math and science content into their design work (i.e., modeling or systematically choosing between possible design solutions). Recommendations for curriculum design and implementation are discussed. 相似文献
