How pre-service teachers navigate trade-offs of food systems across time scales: a lens for exploring understandings of sustainability     

Lina Yamashita  Kathryn Hayes  Cary J. Trexler 《Environmental Education Research》2017,23(3):365-397

In response to the increasing recognition of the need for sustainable food systems, research on students’ and educators’ knowledge of food systems and sustainability more broadly has grown but has generally focused on what people ‘fail’ to understand. Moving away from this deficit approach, the present study used semi-structured interviews to explore how 12 pre-service teachers (PSTs) in the US consider sustainability in terms of the trade-offs – or concurrent costs and benefits – associated with using different agricultural resources over short, medium, and long terms. Drawing upon the constructs of framing, metacognition, and complex causality, the study found that the majority of PSTs referred to indirect experiences of seeing or hearing about agricultural resources to demonstrate stable knowledge of short-term trade-offs and construct tentative knowledge about medium-term trade-offs. Few described long-term trade-offs. Most participants also acknowledged some gaps in their knowledge in discussing trade-offs across the different time scales. Findings suggest the importance of leveraging and building upon educators’ (and ultimately students’) prior experiences to build their understanding of complex trade-offs that underlie food systems. The study also illustrates the value of using the concept of trade-offs across time scales to explore people’s conceptions and understandings of sustainability.  相似文献   

Settler grammars and the Australian professional standards for teachers     

Nikki Moodie  Rachel Patrick 《Asia-Pacific Journal of Teacher Education》2017,45(5):439-454

In 2011, the Australian Institute for Teaching and School Leadership introduced new Professional Standards for Teachers, which require that graduate teachers possess knowledge and understanding of Indigenous students and cultures. The authors conducted interviews with 12 non-Indigenous teacher educators at one Australian university in order to understand how these Standards are interpreted and implemented. We adopt Calderon’s framework of settler grammars to interpret the dialectic of presence and absence that teacher educators in our study describe. Extending this frame to an analysis of the Australian Professional Standards for Teachers, we find that settler grammars function to simultaneously erase Indigenous claims to sovereignty and epistemological equality, whilst promoting a representation of Indigenous people that asserts the primacy of the settler colonial state.  相似文献   

Stancetaking and Language Ideologies in Heritage Language Learner Classroom Discourse     

Rachel E. Showstack 《Journal of Language, Identity & Education》2017,16(5):271-284

Drawing on linguistic anthropological notions of language ideologies and sociolinguistic approaches to stance, this study examines the meaning-making resources through which Spanish heritage language (HL) learners orient toward ideological perspectives on language value and linguistic expertise in classroom interaction. Part of a larger ethnographic study, data in the present study include about 26 hours of audio and video recordings from three different intermediate Spanish HL classrooms and filmed interviews with the students. The analysis indicates that discourses of legitimacy and expertise are embodied within multiple levels of classroom interaction, including affective stancetaking, expert/novice positioning, and the reframing of both ascribed social positions and previous discourse. Results suggest that the role of language ideologies in HL learning can be better understood through an examination of stancetaking in interaction and that the construction of different kinds of expertise should be an important consideration in the development of HL instructional practices.  相似文献   

Leveling the playing field in ICT design: Transcending knowledge roles by balancing division and privileging of knowledges     

Rachel N. Simons  Kenneth R. Fleischmann  Loriene Roy 《The Information Society》2020,36(4):183-198

Abstract

This article develops a conceptual model of users’ and designers’ knowledge roles in the information and communication technology design process. The “ideal” center at the intersection of the axes for division of knowledge work and privileging of knowledges represents a balanced distribution of knowledge work between users and designers and an avoidance of privileging either group over the other. The article then applies this model to analyses of the design process for six video games wherein the knowledges of Indigenous peoples in North America were mobilized. It concludes by discussing implications for research and design practice, particularly for broadening the participation and self-articulation of marginalized groups.  相似文献

Emotion discourse, social cognition, and social skills in children with and without developmental delays     

Fenning RM  Baker BL  Juvonen J 《Child development》2011,82(2):717-731

This study examined parent-child emotion discourse, children's independent social information processing, and social skills outcomes in 146 families of 8-year-olds with and without developmental delays. Children's emergent social-cognitive understanding (internal state understanding, perspective taking, and causal reasoning and problem solving) was coded in the context of parent-child conversations about emotion, and children were interviewed separately to assess social problem solving. Mothers, fathers, and teachers reported on children's social skills. The proposed strengths-based model partially accounted for social skills differences between typically developing children and children with delays. A multigroup analysis of the model linking emotion discourse to social skills through children's prosocial problem solving suggested that processes operated similarly for the two groups. Implications for ecologically focused prevention and intervention are discussed.  相似文献   

Maternal employment, work schedules, and children's body mass index     

Morrissey TW  Dunifon RE  Kalil A 《Child development》2011,82(1):66-81

Previous work has shown that mothers' employment is associated with increases in children's body mass index (BMI), a measure of weight for height. Nonstandard work (working evenings or nights, weekends, or an irregular shift) may also be associated with children's BMI. This article examines the association between maternal work and children's BMI and considers the influence of mothers' nonstandard work schedules. Using data from school-age children (approximately 8 to 12 years) in the NICHD's Study of Early Child Care and Youth Development (N = 990), this study found that an increase in the total time a mother is employed is associated with an increase in her child's BMI; additionally, the association between maternal employment and children's weight is much stronger at 6th grade relative to younger ages. There was no evidence that maternal or home characteristics or children's time use mediated these associations, nor was there any evidence that nonstandard work was associated with children's BMI. Implications for policy and future research are discussed.  相似文献   

Adolescents' development of skills for agency in youth programs: learning to think strategically     

Larson RW  Angus RM 《Child development》2011,82(1):277-294

This research examines how youth in arts and leadership programs develop skills for organizing actions over time to achieve goals. Ethnically diverse youth (ages 13-21) in 11 high-quality urban and rural programs were interviewed as they carried out projects. Qualitative analyses of 712 interviews with 108 youth yielded preliminary grounded theory about youth's development of strategic thinking, defined as use of dynamic systems reasoning to anticipate real-word scenarios and plan work. Strategic thinking appeared to develop through youth's creative engagement with tactical challenges in the work and feedback from the work's outcomes. Program advisors supported this development by giving youth control and by providing nondirective assistance when needed.  相似文献   

The Pell and the Poor: A Regression-Discontinuity Analysis of On-Time College Enrollment     

Rachel B. Rubin 《Research in higher education》2011,52(7):675-692

In this study, I capitalize on a natural experiment to examine the effect of federal Pell Grant eligibility on college enrollment for students who graduated from high school in spring 2004 and who completed the Free Application for Federal Student Aid (FAFSA). Data from the Education Longitudinal Study of 2002 are used to array students on the continuous Expected Family Contribution (EFC) variable, attained from the FAFSA, and divide them into two categories—those with an EFC at or below the federally designated amount for Pell eligibility, and those above. This regression-discontinuity approach allows me to measure whether students who vary regarding their Pell Grant eligibility, but who have essentially identical family incomes, differ in their college enrollment rates. I find no effect. While confirming prior studies examining the impact of the Pell Grant on college enrollment for traditional students, this finding remains inconsistent with findings on other need-based grants. This result suggests that the minimum Pell Grant amount, currently less than 10% of an average college’s tuition and fees, may be insufficient.  相似文献   

A review of the acculturation experiences of international students     

Rachel A. Smith  Nigar G. Khawaja 《Int J Intercult Relat》2011,35(6):699-713

Universities in Western countries host a substantial number of international students. These students bring a range of benefits to the host country and in return the students gain higher education. However, the choice to study overseas in Western countries may present many challenges for the international student including the experience of acculturative stress and difficulties with adjustment to the environment of the host country. The present paper provides a review of current acculturation models as applied to international students. Given that these models have typically been empirically tested on migrant and refugee populations only, the review aims to determine the extent to which these models characterise the acculturation experience of international students. Literature pertaining to salient variables from acculturation models was explored including acculturative stressors encountered frequently by international students (e.g., language barriers, educational difficulties, loneliness, discrimination, and practical problems associated with changing environments). Further discussed was the subsequent impact of social support and coping strategies on acculturative stress experienced by international students, and the psychological and sociocultural adaptation of this student group. This review found that the international student literature provides support for some aspects of the acculturation models discussed; however, further investigation of these models is needed to determine their accuracy in describing the acculturation of international students. Additionally, prominent acculturation models portray the host society as an important factor influencing international students’ acculturation, which suggests the need for future intervention.  相似文献
