Expert-Novice Differences in Cognitive and Skill Execution Components of Youth Baseball Performance

Abstract

Previous research has shown that experts exhibit superior response selection and skill execution during performance in youth sport. The purpose of this study was to examine differences in cognitive and skill execution components of game performance in young baseball players (N = 159) with, varying levels of expertise. Three levels of expertise (low-, average-, and high-skilled players) were identified at each age level (7, 8, 9, and 10 years of age). Game performance was videotaped, and measures of skill execution (throwing accuracy, throwing force, fielding, catching, batting average, and batting contact) and cognitive components (positioning, decisions) were developed from observational analysis. The results indicated that baseball skill execution during game play maximally discriminated expertise levels.     

Investigating the “black box” of effective teaching: the relationship between teachers’ perception and student achievement in a large urban district

Given the international need to improve student learning, there is nothing more important than classroom teachers. Obtaining a deeper understanding of effective classrooms is a priority if educational reform efforts are to succeed in any educational system around the world. In the last decade, educational researchers have expanded the knowledge base about the impact of teachers, but far less is known about what effective teachers do that make such a positive difference. This investigation focuses on the relationship between attributes of effective teaching, as perceived by both more and less effective teachers, and fourth grade reading achievement results of their students. This investigation used value-added modeling methods as the first step for identifying the more and less effective fourth grade teachers (N?=?261) and their students (N?=?6,962). Survey research methods were used to compare the perceptions about characteristics of effective teaching for teachers previously identified—in the value-added model—as (a) more effective and (b) less effective. Findings indicated that the more effective teachers value classroom management and organization as the number one characteristic of effective teaching; that, in turn, enables the more effective teachers to focus classroom time on student learning. Implications for theory and practice are discussed.     

Reflections on healing: framing strategies utilized by acquaintance rape survivors

This study examines the stories acquaintance rape victims tell through semi-structured interviews. Acquaintance rape, viewed here as a particularly paradoxical crime, creates a need for women to resolve the inconsistency of their experience. By conducting interviews with victims and analyzing their verbal communication, this project explores how victims frame their rape experience. Framing strategies used by victims of sexual harassment served as a guide for the initial identification of framing strategies for victims of acquaintance rape. Women in this study utilized strategies of paradox management to assess blame, define, and reframe their experiences. Recognition of these management strategies can assist social support networks and law enforcement professionals in identifying the communicative strategies of female victims of varying types of violence.     

Classroom use of the occasional speech

An examination of the promotional brochures distributed by the chautauqua circuits between 1904–1932 illustrates how they reflected the social‐intellectual themes of the period and how they adapted to changing audiences and markets.     

Interleukin-6 and delayed onset muscle soreness do not vary during the menstrual cycle

The purpose of this study was to determine if a difference in interleukin-6 (IL-6) and delayed onset muscles soreness (DOMS) exists in two different phases of the menstrual cycle. Nine runners performed one 75-min high-intensity interval running session during the early follicular (EF) phase and once during the midluteal (ML) phase of the menstrual cycle. Estrogen and progesterone levels were significantly reduced in the EF phase when compared to the ML phase. IL-6 levels increased from pre- to postexercise in the EF and ML phases (p < .001). There was no relationship between the IL-6 level and DOMS. The results suggest that menstruating female runners need not vary training throughout the month to reduce DOMS.     

Ethnic and Racial Identity in Adolescence: Implications for Psychosocial,Academic, and Health Outcomes

The construction of an ethnic or racial identity is considered an important developmental milestone for youth of color. This review summarizes research on links between ethnic and racial identity (ERI) with psychosocial, academic, and health risk outcomes among ethnic minority adolescents. With notable exceptions, aspects of ERI are generally associated with adaptive outcomes. ERI are generally beneficial for African American adolescents' adjustment across all three domains, whereas the evidence is somewhat mixed for Latino and American Indian youth. There is a dearth of research for academic and health risk outcomes among Asian American and Pacific Islander adolescents. The review concludes with suggestions for future research on ERI among minority youth.     

Feeling Good,Happy, and Proud: A Meta‐Analysis of Positive Ethnic–Racial Affect and Adjustment

One point of intersection in ethnic and racial identity research is the conceptual attention paid to how positively youth feel about their ethnicity or race, or positive ethnic–racial affect. This article reports results of a series of meta‐analyses based on 46 studies of this dimension and psychosocial, academic, and health risk outcomes among ethnic and racial minority youth. The overall pattern of results suggests that positive ethnic–racial affect exhibited small to medium associations (r range = |.11| to |.37|) with depressive symptoms, positive social functioning, self‐esteem, well‐being, internalizing, externalizing, academic achievement, academic attitudes, and health risk outcomes. Implications for theory and research about the role of positive ethnic–racial affect among youth growing up in an increasingly diverse society are discussed.     

Early College Awareness as an Enrollment Management Strategy

The Institute of Medicine and The Educated Citizen and Public Health Initiative suggest that an understanding of public health is a core component of an educated public and is necessary to develop social responsibility (Association of American Colleges and Universities [AAC&;U], 2011 Association of American Colleges and Universities (AAC&;U) . ( 2011 ). The educated citizen and public health . Retrieved from http://www.aacu.org/public_health/  [Google Scholar]; National Research Council, 2003 National Research Council . ( 2003 ). Who will keep the public healthy? Educating public health professionals for the 21 st century (Consensus report). Washington, DC: The National Academies Press.  [Google Scholar]). To respond to this call, the University of New Hampshire collaborated with faculty from the New Hampshire Community College System to introduce the public health field through a course called Global Public Health Issues. This article will discuss the development, implementation, and evaluation of a public health course between a two-year and four-year college. It will also discuss the potential for such a partnership and public health course to encourage life-long learning and a commitment to social responsibility, allow for new course/major/minor development in public health, enable faculty to expand their expertise, broaden the attractiveness of two-year colleges, and introduce a vocation-based student population to the value of public health and the public health workforce.
