Information literacy in science writing: how students find,identify, and use scientific literature     

Kristin M. Klucevsek  Allison B. Brungard 《International Journal of Science Education》2016,38(17):2573-2595

For undergraduate students to achieve science literacy, they must first develop information literacy skils. These skills align with Information Literacy Standards and include determining appropriate databases, distinguishing among resource types, and citing resources ethically. To effectively improve information literacy and science literacy, we must identify how students interact with authentic scientific texts. In this case study, we addressed this aim by embedding a science librarian into a science writing course, where students wrote a literature review on a research topic of their choice. Library instruction was further integrated through the use of an online guide and outside assistance. To evaluate the evolution of information literacy in our students and provide evidence of student practices, we used task-scaffolded writing assessments, a reflection, and surveys. We found that students improved their ability and confidence in finding research articles using discipline-specific databases as well as their ability to distinguish primary from secondary research articles. We also identified ways students improperly used and cited resources in their writing assignments. While our results reveal a better understanding of how students find and approach scientific research articles, additional research is needed to develop effective strategies to improve long-term information literacy in the sciences.  相似文献   

Assessing and Predicting Small-Group Literacy Instruction in Early Childhood Classrooms     

Kristin Sue Farley  Shayne Piasta  Mine Dogucu  Ann O’Connell 《Early education and development》2017,28(4):488-505

Research Findings: The present study assessed the extent to which early childhood educators utilized small-group literacy instruction and explored factors potentially associated with the use of this evidence-based practice. The classroom activities of 83 early childhood educators were observed in the fall and spring, and videos were coded to calculate time spent in small-group literacy instruction. Educators completed questionnaires indicating classroom adult:child ratios, literacy beliefs, and feelings of self-efficacy. Classroom Assessment Scoring System scores for classroom organization and instructional support measured the quality of classroom management and instructional interactions, respectively. On average, educators provided 11.4 min (SD = 10.6) of small-group literacy instruction a day. It is notable that many educators provided little or no small-group literacy instruction. Negative binomial regression analyses indicated that educators with better classroom management, higher quality instructional interactions, and lower adult:child ratios were more likely to use small-group literacy instruction. Educators’ beliefs and feelings of self-efficacy were not associated with the use of small-group literacy instruction. Practice or Policy: Educators may be better able to provide small-group literacy instruction in contexts affording low adult:child ratios and high levels of classroom management and instructional support, all of which are malleable factors that can be changed via policy or professional development.  相似文献

Peeling Back the Layers of Policy and School Reform: Revealing the structural and social complexities within     

Haley Woodside‐Jiron  Kristin M. Gehsmann 《International Journal of Disability, Development & Education》2009,56(1):49-72

This article explores the complex process of school change over a six‐year period in one high‐poverty, urban elementary school in a northeastern city of the United States. The school included in this instrumental case study was identified by its State Department of Education as “being in need of improvement” in March 2000. Findings suggest that creating opportunities for context‐based solutions, curricular coherence, and responsive and consistent coaching were the necessary means for leveraging change at this school. Further, responding to the layers and iterations of educational policy, and addressing the deeper social issues intimately associated with serving high‐poverty communities, was essential. We identify policy issues that contributed to the complexity of this school’s improvement efforts. Our analysis extends beyond surface‐level documentation of the school’s inputs and outputs, and illustrates what it means to meet individual students’ needs in complex social and institutional spaces. We also discuss social justice issues that are linked with current policies targeting improved outcomes for all children.  相似文献

Opportunities and constraints when studying social learning: Developmental approaches and social factors     

Elizabeth V. LonSdorf  Kristin E. Bonnie 《Learning & behavior》2010,38(3):195-205

Identifying social learning in wild populations is complicated by the relative lack of ability to conduct controlled experiments in natural habitats. Even in more controlled captive settings, tracking the innovation and spread of behavior among known individuals can be challenging, and these studies often suffer from a lack of ecological validity. In recent years, a host of new approaches have been undertaken to attempt to provide more quantitative control and empirical demonstration of social learning, both in the wild and in captive settings that more closely mimic natural contexts. Developmental approaches are being undertaken more regularly that allow us to study the ontogenetic trajectory of complex skills in a variety of taxa. Likewise, a spirited focus on the social context of social learning has emerged, and researchers have begun to meticulously analyze the influences of social systems and the characteristics of demonstrators and observers. Here, we provide a review of these studies and summarize the opportunities and constraints that exist when one attempts to study learning in social species. We suggest that although the study of social learning in nonhuman animals is becoming much more complex, addressing this complexity provides a fruitful model for understanding the evolution of human cultural behavior.  相似文献   

In-season changes in ventricular morphology and systolic function in adolescent female athletes     

Andrew M. Watson  Carol Coutinho  Kristin Haraldsdottir  Stacey Brickson  Warren Dunn  Marlowe Eldridge 《European Journal of Sport Science》2018,18(4):534-540

Purpose: To evaluate the influence of physical maturity on the changes in ventricular morphology and function with sport training in female youth athletes.

Methods: Thirty-two female athletes (age 13–18 years) underwent height and weight measurement and 2-D echocardiographic evaluation immediately prior to, and following, a 20-week soccer season. Pre- and post-season left ventricular end-diastolic diameter (LVEDD), end-diastolic volume (LVEDV), ejection fraction (LVEF), stroke volume (LVSV), mass (LVM), and posterior wall thickness (LVPWT), right ventricular end-diastolic diameter (RVEDD), end-diastolic area (RVEDA), and fractional area change (RVFAC), and interventricular septal thickness (IVST) were compared. In-season change in each variable was compared across pre-season hours of vigorous physical activity (0–1, 2–3, >3 hours).

Results: Significant increases were identified in LVEDV (51.3?±?10.4?v 56.4?±?9.6?ml/m², p?=?0.001) and RVEDA (10.5?±?1.9?v 11.3?±?2.5?cm²/m², p?=?0.040), but not LVEDD, LVM, LVPWT, LVSV, RVEDD, RVEDA, RVFAC, or IVST (p?>?0.05 for all). In-season changes in echocardiographic variables did not differ across hours of pre-season vigorous physical activity (p?>?0.05 for all).

Conclusion: Among female adolescent soccer players, in-season training elicits changes in resting ventricular volume, but not wall thickness or systolic function. These adaptations do not appear to be influenced by pre-season physical activity level.  相似文献   

Young children's near and far transfer of the basic theory of natural selection: An analogical storybook intervention          下载免费PDF全文

Natalie Emmons  Kristin Lees  Deborah Kelemen 《科学教学研究杂志》2018,55(3):321-347

Misconceptions about adaptation by natural selection are widespread among adults and likely stem, in part, from cognitive biases and intuitive theories observable in early childhood. Current educational guidelines that recommend delaying comprehensive instruction on the topic of adaptation until adolescence, therefore, raise concerns because children's scientifically inaccurate theories about species may be left unchallenged for many years, allowing them to entrench and become difficult to overcome. In consequence, this investigation sought to explore whether classrooms of kindergartners and second graders could acquire a basic but comprehensive understanding of adaptation from an intervention constructed around two picture storybooks that mechanistically explain natural selection. Learning was assessed in near and far transfer contexts both immediately and a month later. Kindergartners and second graders demonstrated substantial learning of biological information; however, second graders showed pronounced abilities to near and far generalize, immediately and over time. Results suggest that causally cohesive interventions with an emphasis on mechanistic explanation facilitate children's classroom learning of complex counterintuitive scientific ideas.  相似文献   

Protective Factors as Predictors of Suicide Risk Among Graduate Students          下载免费PDF全文

Kristin L. Bruns  Amber Letcher 《Journal of College Counseling》2018,21(2):111-124

The purpose of this study was to examine protective factors as predictors of suicide risk among graduate students (n = 413) at a large midwestern university. Using binary logistic regression, the authors assigned students to risk classifications (i.e., nonrisk group or suicide risk group). Results indicated emotional stability as the strongest predictor for participants’ placement into the nonrisk or suicide risk group. The authors discuss implications for counselors and directors of college counseling centers, as well as directions for future research.  相似文献
