First-rib stress fracture in two adolescent swimmers: a case report     

Sara Low  Michael Kern 《Journal of sports sciences》2016,34(13):1266-1270

First-rib stress fractures have been described in adolescent athletes in various sports, with only one prior case report of first-rib stress fractures in an adolescent female swimmer. There is a need for research on the cause, management, and prevention of these injuries as they lead to significant morbidity and critical time away from sport for these aspiring athletes. We aimed to describe first-rib stress fractures as a potential cause for non-specific atraumatic chronic shoulder pain in adolescent swimmers and to discuss the different presentations, unique risk factors, treatment, and potential injury prevention strategies of such fractures. We discussed two such cases which were successfully treated with activity modification with restriction of all overhead activity, gradually progressive physical therapy and a return to swimming protocol. First-rib stress fractures can vary in presentation and should be in the differential diagnosis in adolescent swimmers with chronic shoulder pain. These injuries can be successfully managed with rest from overhead activities and physical therapy. Gradual return to competitive swimming can be achieved even with non-union of a first-rib stress fracture. Emphasis on balanced strength training in different muscle groups and proper swimming technique is essential to prevent these injuries.  相似文献   

Academic socialization,parental educational expectations,and academic self‐efficacy among Latino adolescents     

Fernanda L. Cross  Aixa D. Marchand  Michael Medina  Andrea Villafuerte  Deborah Rivas‐Drake 《Psychology in the schools》2019,56(4):483-496

This study examined the direct association between parental educational expectations and adolescents’ academic self‐efficacy, as well as the moderating influence of parental academic socialization messages. Participants were 148 Latino parent–adolescent dyads with the majority of Mexican origin (80.4%). Most of the parent participants were mothers (85.8%). Adolescents were 13 (46%) or 14 (54%) years of age, and 53% identified as female. Adolescents reported their academic self‐efficacy and perceptions of their parents’ educational expectations; parents reported on their academic socialization messages of shame/pressure and effort regarding academics. The results suggest that, after accounting for parents’ level of education and immigrant status, parental educational expectations were positively associated with adolescent academic self‐efficacy. This association was stronger among adolescents whose parents reported transmitting fewer messages of shame/pressure and academic effort. These results point to the importance of nuances in the content and type of academic socialization messages within Latino families.  相似文献   

Teacher and school characteristics and their influence on curriculum implementation     

Gillian H. Roehrig  Rebecca A. Kruse  Anne Kern 《科学教学研究杂志》2007,44(7):883-907

Reform‐based curriculum materials have been suggested as a mechanism to make inquiry‐based instruction more prevalent in secondary science classrooms, specifically when accompanied by comprehensive professional development (Loucks‐Horsley, Hewson, Love, & Stiles, 1998 ; Powell & Anderson, 2002 ). This research examines the implementation of a reform‐based high school chemistry curriculum in a large, urban school district. We explicitly consider the role of the teachers' knowledge and beliefs in their implementation of the reform‐based chemistry curriculum, as well as school level factors. Qualitative and quantitative data were collected in the form of beliefs interviews and classroom observations from 27 high school chemistry teachers. Analysis of the data revealed that implementation of the curriculum was strongly influenced by the teachers' beliefs about teaching and learning, and the presence of a supportive network at their school sites. © 2007 Wiley Periodicals, Inc.

Interactive Training Model: Enhancing Beginning Counseling Student Development     

Derrick A. Paladino  Casey A. Barrio Minton  Carolyn W. Kern 《Counselor Education & Supervision》2011,50(3):189-206

The authors propose the Interactive Training Model (ITM), a full classroom role play experience, as a method for helping student counselors develop essential interviewing and counseling skills and self‐awareness as required by the 2009 Council for Accreditation of Counseling and Related Educational Programs Standards. This pre‐post, quasiexperimental study involving 45 master's‐level students indicated that those who participated in the ITM made greater gains in supervisee development compared with those who participated in a traditional peer feedback model. Narrative student feedback regarding the use of ITM in an essential skills course is presented, and implications for counselor education are discussed.  相似文献   

PERCEPTIONS AND PRACTICES OF CULTURALLY RELEVANT SCIENCE TEACHING IN AMERICAN INDIAN CLASSROOMS     

Younkyeong Nam  Gillian Roehrig  Anne Kern  Bree Reynolds 《International Journal of Science and Mathematics Education》2013,11(1):143-167

This study explores the perceptions of culturally relevant science teaching of 35 teachers of American Indian students. These teachers participated in professional development designed to help them better understand climate change science content and teaching climate change using both Western science and traditional and cultural knowledge. Teacher perceptions of practices using culturally relevant instruction were evaluated. The data were analyzed both quantitatively and qualitatively. The results from the survey analysis show that the teachers’ existing practices of culturally relevant science teaching were limited in choosing topics relevant to American Indian culture. We found three common themes from the teachers’ perceptions of culturally relevant science teaching, meaning of culturally relevant science teaching, teaching strategies, and purpose of culturally relevant science teaching from the qualitative data. We also found that teachers with higher survey scores perceive culturally relevant science teaching differently than teachers with lower survey scores, specifically for the purposes and teaching strategies of culturally relevant science teaching. The results show that teachers with higher survey scores tended to perceive culturally relevant science teaching as a two-way learning process between teachers and students where the teachers can learn traditional science knowledge from the students. They also tend to perceive using concrete traditional science examples as effective teaching strategy for culturally relevant science teaching and building strong relationships with American Indian students as the most important purpose of culturally relevant science teaching. We also discuss common challenges faced by science teachers when trying to implement culturally relevant science teaching with American Indian students.  相似文献   

A DEAN'S AND DEPARTMENT CHAIR'S GUIDE TO DOCUMENTING COMPETENCY‐BASED PROGRAM ANALYSIS AND DESIGN IN THE 2‐YEAR COLLEGE     

Ronald P. Kern 《Community College Journal of Research & Practice》2013,37(4):345-350

Changes in the new Carl D. Perkins Vocational and Applied Technology Education Act of 1990 have added to existing state and regional accrediting agency pressures for competency‐based instruction. Because of these increasing pressures, deans, department chairs, and administrators of federal vocational funds administered under the act are, and will continue to be, required to provide evidence that their programs are competency based. A three‐step model to competency‐based programs as well as administrator guidelines for needed documentation are presented.  相似文献

Experimental Control of Simple Pendulum Model     

C. Medina 《Science & Education》2004,13(7-8):631-640

This paper conveys information about a Physicslaboratory experiment for students with some theoretical knowledge about oscillatory motion. Students construct a simple pendulum that behaves as an ideal one, and analyze model assumption incidence on its period. The following aspects are quantitatively analyzed: vanishing friction, small amplitude, not extensible string, point mass of the body, and vanishing mass of the string. It is concluded that model assumptions are easilyaccomplished in practice, within small experimental errors. Furthermore, this way of carrying out the usual pendulum experiments promotes a better understanding of the scientific modeling process. It allows a deeper comprehension of those physical concepts associated with model assumptions (small amplitude, point mass, etc.), whose physical and epistemological meanings appear clearly related to the model context. Students are introduced to a scientific way of controlling the validity of theoretical development, and they learn to value the power and applicability of scientific modeling.  相似文献   

In the Name of Teaching: The Embodied Journey of a Different Kind of Educator     

Yolanda Medina 《Educational Studies A Journal of the American Educational Studies Association》2016,52(2):177-187

The use of autobiography in the development of teacher identity can lead to a deeper critical examination of how issues of race, social class, gender, and gender identity affect experience and worldview. This path can helps future teachers become more attuned to the issues they will confront in their classrooms. In this speech, the author shares her own personal experiences to illustrate this aforementioned point. She shares her educational autobiography and highlights those educators who helped shape her educational practice and the relationship she has with her students.  相似文献   

Peer Review in Education: Promoting Collaboration, Written Expression, Critical Thinking, and Professional Responsibility     

Vinícius Medina Kern  Luciana Martins Saraiva  Roberto Carlos dos Santos Pacheco 《Education and Information Technologies》2003,8(1):37-46

This article discusses the application of the peer review process as a pedagogical instrument for the promotion of written expression, collaborative work, critical thinking, and professional responsibility among Informatics and Engineering majors. The approach is introduced with a motivation, followed by a discussion about common principles of current learning paradigms and the peer review process. This work is being conducted in Brazil, where we intend to promote a learning paradigm shift through the application of peer review in education. A framework for this application is outlined, together with an account of results from experiences and a discussion about the skills that this approach exercises, especially with regard to widely accepted curricula and codes of ethics and professional conduct. Further research and development efforts are conjectured.  相似文献
