Using participatory action research (PAR), this paper explores the ethical practice of students engaged in practitioner research in a higher education context. Using narrative enquiry, the paper explores the participants’ experiences of practitioner research, including ethical dilemmas that resulted from a conflict of values between the practitioner and research roles. We postulate a multi-dimensional approach to ethical practice known as ‘ethical posture’ emerging from our consideration of conceptions of inquiry that resulted in contrasting ethical behaviour. 相似文献

Geospatially enabled learning technologies may enhance Earth science learning by placing emphasis on geographic space, visualization, scale, representation, and geospatial thinking and reasoning (GTR) skills. This study examined if and how a series of Web geographic information system investigations that the researchers developed improved urban middle-school learners’ GTR skills and their understanding of tectonics concepts. Paired-sample t tests for analyses of tectonics content knowledge and GTR achievement measures revealed statistically significant gains from pretest to posttest (p <.001) with large effect sizes. The findings provide support that GTR related to tectonics can be learned with appropriately designed learning activities using Web-based geographic information systems. 相似文献

Development of early math skill depends on a prerequisite level of cognitive development. Identification of specific cognitive skills that are important for math development may not only inform instructional approaches but also inform assessment approaches to identifying children with specific learning problems in math. This study investigated the specific cognitive correlates of math problem solving across early grade levels (1–4) while controlling for basic calculation skills. As expected, basic calculation skill was a significant predictor of math problem solving across the entire sample. However, the addition of cognitive measures almost doubled the variance explained (R2 = .61). Additionally, only select cognitive variables contributed to the prediction of math problem solving, and these variables change in importance as children develop higher‐level math skills. Results are discussed within a developmental model, which emphasizes the increasing importance of abstract code representations required in higher levels of math performance. 相似文献

Reducing Risk for Substance Use by Economically Disadvantaged Young Men: Positive Family Environments and Pathways to Educational Attainment 下载免费PDF全文
Monica J. Martin Rand D. Conger Stephanie L. Sitnick April S. Masarik Erika E. Forbes Daniel S. Shaw 《Child development》2015,86(6):1719-1737
Using prospective, longitudinal data spanning 10 years (age = 10–20) from a study of 295 economically disadvantaged males, the current investigation evaluated a developmental model that links early family environment and later educational aspirations, extracurricular activities, and educational attainment to substance use in early adulthood. The results indicate that a positive family environment during adolescence (low family conflict, high family warmth, and effective child management) predicted educational involvements during adolescence that promoted educational attainment during early adulthood. Finally, higher levels of educational attainment were associated with less substance use in early adulthood, even after controlling for adolescent substance use. These findings suggest that positive parenting promotes educational achievements that increase resilience to substance use for economically disadvantaged males. 相似文献

Developmental Differences in Relations Between Episodic Memory and Hippocampal Subregion Volume During Early Childhood 下载免费PDF全文

Episodic memory shows striking improvement during early childhood. However, neural contributions to these behavioral changes are not well understood. This study examined associations between episodic memory and volume of subregions (head, body, and tail) of the hippocampus—a structure known to support episodic memory in school‐aged children and adults—during early childhood (n = 45). Results revealed significant positive relations between episodic memory and volume of the hippocampal head in both the left and right hemispheres for 6‐ but not 4‐year‐old children, suggesting brain–behavior relations vary across development. These findings add new information regarding neural mechanisms of change in memory development during early childhood and suggest that developmental differences in hippocampal subregions may contribute to age‐related differences in episodic memory ability. 相似文献

Mindfulness‐based awareness and compassion were examined as predictors of empathy and anxiety among 152 master's‐level counseling interns. Results of hierarchical multiple regression analysis supported that awareness and compassion differentially contributed to explaining the variance in counselor empathy and anxiety. Implications for counselor education are discussed. 相似文献

The purpose of Science in Action (SIA) was to examine the relationship between implementing quality science, technology, engineering, and math (STEM) service-learning (SL) projects and the effect on students' academic engagement in middle school science, civic responsibility, and resilience to at-risk behaviors. The innovative project funded by the Corporation for National and Community Service (CNCS) included 6,000+ middle school at-risk students (eligible for at least 50% free or reduced-cost lunch), 126 science teachers who integrated STEM problem-based SL pedagogy into science instruction to teach students to solve real problems in schools and communities. The project involved 20 schools and communities with assistance from 120 community partners. Participants completed pre- and post-SL surveys on academic engagement, civic responsibility, and resilience; qualitative data were collected from journals, interviews, focus groups, observations, and field notes. Results highlight exemplary SL projects that demonstrated increased student academic engagement and achievement for students living in high poverty areas with potential at-risk behavior. Implications for future research and educational practices are discussed. 相似文献

Workplaces are settings where power, knowledge and self are brought together in a complex social environment which includes various forms of struggle related to identity, agency, socio-cultural norms, political structures and functional practices. The purpose of this article is to uncover how formal and informal work-related learning processes influence the identity transformation of workers with low literacy and essential skills. Drawing on two recent Canadian data bases which serve as cases in this study, the position taken by the authors is that the organisational context can both facilitate and impede worker subjectivity. Various conditions, approaches to learning and training pathways are examined as they contribute to social cognitive and transformative learning theories. 相似文献
