THE BULLYING DYNAMIC: PREVALENCE OF INVOLVEMENT AMONG A LARGE‐SCALE SAMPLE OF MIDDLE AND HIGH SCHOOL YOUTH WITH AND WITHOUT DISABILITIES     

Chad A. Rose  Cynthia G. Simpson  Aaron Moss 《Psychology in the schools》2015,52(5):515-531

Bullying has been the topic of much debate and empirical investigations over the past decade. Contemporary literature contends that students with disabilities may be overrepresented within the bullying dynamic as both perpetrators and victims. Unfortunately, prevalence rates associated with the representation of students with disabilities is limited due to measurement, disability status identification, and definition issues. The present study attempted to address these issues by assessing the prevalence rates of specific subgroups of students with disabilities in a large‐scale cross‐sectional study with 13,325 students without disabilities and 1,183 students with disabilities in Grades 6 through 12. Results suggest that overall, students with disabilities reported proportionally higher rates of bullying, fighting, relational aggression, victimization, online victimization, and relational victimization than did their peers without disabilities. These findings suggest that schools must begin to establish targeted interventions to support skill development based on characteristics associated with specific disability identification.  相似文献   

Are the Yo-Yo intermittent recovery test levels 1 and 2 both useful? Reliability,responsiveness and interchangeability in young soccer players

Abstract

The aim of this study was to compare the reliability, internal responsiveness and interchangeability of the Yo-Yo intermittent recovery test level 1 (YY1), level 2 (YY2) and submaximal YY1 (YY1-sub). Twenty-four young soccer players (age 17 ± 1 years; height 177 ± 7 cm; body mass 68 ± 6 kg) completed each test five times within pre- and in-season; distances covered and heart rates (HRs) were measured. Reliability was expressed as typical error of measurement (TEM) and intraclass correlation coefficient (ICC). Internal responsiveness was determined as effect size (ES) and signal-to-noise ratio (ES_TEM). Interchangeability was determined with correlation between training-induced changes. The TEM and ICC for distances in the YY1 and YY2 and for HR in YY1-sub were 7.3% and 0.78, 7.1% and 0.93 and 2.2% and 0.78, respectively. The ESs and ES_TEMs were 0.9 and 1.9 for YY1, 0.4 and 1.2 for YY2 and ?0.3 and ?0.3 for YY1-sub. Correlations between YY1 vs. YY2 and YY1-sub were 0.56 to 0.84 and ?0.36 to ?0.81, respectively. Correlations between change scores in YY1 vs. YY2 were 0.29 and ?0.21 vs. YY1-sub. Peak HR was higher in YY1 vs. YY2. The YY1 and YY2 showed similar reliability; however, they were not interchangeable. The YY1 was more responsive to training compared to YY2 and YY1-sub.  相似文献

STEM Is Elementary: Challenges Faced by Elementary Teachers in the Era of the Next Generation Science Standards     

Aaron D. Isabelle 《The Educational forum》2017,81(1):83-91

For students to achieve the goals of the Next Generation Science Standards (NGSS) by Grade 12, thinking and acting like scientists and engineers must begin in the elementary grades. However, elementary teachers may find this challenging -because language arts and mathematics still dominate many classrooms—often at the expense of science. This essay examines the science skills elementary students are expected to learn and how teachers and administrators can approach the increased demands of NGSS.  相似文献   

Understanding mathematics textbooks through reader-oriented theory     

Aaron Weinberg  Emilie Wiesner 《Educational Studies in Mathematics》2011,76(1):49-63

Textbooks have the potential to be powerful tools to help students develop an understanding of mathematics. However, many students are unable to use their textbooks effectively as learning tools. This paper presents a framework that can be used to analyze factors that impact the ways students read textbooks. It adapts ideas from reader-oriented theory and applies them to the domain of mathematics textbooks. In reader-oriented theory, the reader is viewed as actively constructing meaning from a text through the reading process; this endeavor is shaped and constrained by the intentions of the author, the beliefs of the reader, and the qualities the text requires the reader to possess. This paper also discusses how reading mathematics textbooks is further constrained by the authority and closed structure of these textbooks. After describing the framework, the paper discusses recommendations for future avenues of research and pedagogy, highlighting the importance of teachers' roles in mediating their students' use of textbooks.  相似文献   

VIII. THE SITUATION FOR CHILDREN WITHOUT PARENTAL CARE AND STRATEGIES FOR POLICY CHANGE     

Patrice L. Engle  Victor K. Groza  Christina J. Groark  Aaron Greenberg  Kelley McCreery Bunkers  Rifkat J. Muhamedrahimov 《Monographs of the Society for Research in Child Development》2011,76(4):190-222

Research that clearly demonstrates the negative effects of institutionalization, particularly for young children, has been critical for changing policy. However, actually putting science into action requires advocacy, persistence, and perseverance. Policy makers and advocates must be informed about the research and use it effectively. This paper proposes a number of key components for translating research into policy and programs: analyzing the situation, using evidence to build the case for action, developing policies, building program capacity in child welfare and early childhood development, creating a family‐based child welfare system, and developing a system of monitoring and accountability. Much of the knowledge in this paper comes from experiences, desk reviews, and case studies of successful practices. Research provides the basis, but moving research to practice depends on collaboration between researchers who understand the key policy perspectives and policy makers who understand the research.  相似文献   

Understanding complex ecologies: an investigation of student experiences in adventure learning programs     

Suzan Koseoglu  Aaron Doering 《Distance Education》2011,32(3):339-355

The GoNorth! Adventure Learning (AL) Series delivered educational programs about global climate change and sustainability from 2006 to 2010 via a hybrid-learning environment that included a curriculum designed with activities that worked in conjunction with the travels of Team GoNorth! as they dog sledded throughout the circumpolar Arctic. This study addresses a gap in the AL literature by identifying factors that lead to high levels of student engagement and reveals strategies for instructional designers and educators on how to design emotionally engaging online learning environments. A mixed methods study was conducted to explore patterns of learner engagement in relation to two AL programs: GoNorth! Fennoscandia 2008 and GoNorth! Nunavut 2009. Survey data were drawn from a total of 101 students in 2008 and 2009.  相似文献   

Theo Jansen project in engineering design course and a design example     

Yucheng Liu  Aaron Artigue  Jeremy Sommers  Terence Chambers 《European Journal of Engineering Education》2011,36(2):187-198

Objectives of a project-oriented mechanical engineering course, Engineering Design, were achieved through a design project, where students designed, built and demonstrated an extreme version of a basic Theo Jansen device. Through this project, junior students in the University of Louisiana fully developed the capability of applying mathematic and kinematic knowledge in the analysis and design of mechanisms. Students also developed oral and written communication skills, which would be used in design environments, through the presentation of results in both oral and written forms. An assessment of the design project indicated that effective teaching and learning spread through the semester, with the junior students acting as project managers and experiencing design practices. An example of a student-designed Theo Jansen device is presented in this paper to show the study results achieved by the students.  相似文献
