The effect of playing formation on high-intensity running and technical profiles in English FA Premier League soccer matches

Abstract

The aim of this study was to examine the effect of playing formation on high-intensity running and technical performance during elite soccer matches. Twenty English FA Premier League games were analysed using a multiple-camera computerized tracking system (n = 153 players). Overall ball possession did not differ (P > 0.05) between 4–4–2, 4–3–3 and 4–5–1 formations (50%, s = 7 vs. 49%, s = 8 vs. 44%, s = 6). No differences were observed in high-intensity running between 4–4–2, 4–3–3 and 4–5–1 formations. Compared with 4–4–2 and 4–3–3 formations, players in a 4–5–1 formation performed less very high-intensity running when their team was in possession (312 m, s = 196 vs. 433 m, s = 261 vs. 410 m, s = 270; P < 0.05) but more when their team was not in possession (547 m, s = 217 vs. 461 m, s = 156 vs. 459 m, s = 169; P < 0.05). Attackers in a 4–3–3 performed ～30% more (P < 0.05) high-intensity running than attackers in 4–4–2 and 4–5–1 formations. However, the fraction of successful passes was highest in a 4–4–2 (P < 0.05) compared with 4–3–3 and 4–5–1 formations. The results suggest that playing formation does not influence the overall activity profiles of players, except for attackers, but impacts on very high-intensity running activity with and without ball possession and some technical elements of performance.     

Digital pilgrimage: Exploring Catholic monastic webcasts

This study questions how religious webmasters view the objectives of their webcasting in relation to pilgrimage. Findings uncovered four facets: (1) mediation of the holy sites and experience; (2) bonding between Holy Land communities and global believers; (3) cultivating agents; (4) media experiences as a pilgrimage surrogate. Drawing on Walter Benjamin, the study elucidates how online videos evoke proximity to the sacred, thus connecting holy sites and believers, while affirming webmasters as secondary actors of religious authority.     

Teacher use of evidence to customize inquiry science instruction

This study investigated how professional development featuring evidence‐based customization of technology‐enhanced curriculum projects can improve inquiry science teaching and student knowledge integration in earth science. Participants included three middle school sixth‐grade teachers and their classes of students (N = 787) for three consecutive years. Teachers used evidence from their student work to revise the curriculum projects and rethink their teaching strategies. Data were collected through teacher interviews, written reflections, classroom observations, curriculum artifacts, and student assessments. Results suggest that the detailed information about the learning activities of students provided by the assessments embedded in the online curriculum motivated curricular and pedagogical customizations that resulted in both teacher and student learning. Customizations initiated by teachers included revisions of embedded questions, additions of hands‐on investigations, and modifications of teaching strategies. Student performance improved across the three cohorts of students with each year of instructional customization. Coupling evidence from student work with revisions of curriculum and instruction has promise for strengthening professional development and improving science learning. © 2010 Wiley Periodicals, Inc.

Linkages Among Preschoolers' Playground Behavior, Outcome Expectations, and Parental Disciplinary Strategies

To explore relationships among parent's self-reported disciplinary strategies, preschoolers' outcome expectations, and playground behavior, 136 mothers of preschool-age children (age range = 39-71 months) participated in home disciplinary style interviews. Measures of preschoolers' outcome expectations and observations of childrens' prosocial, antisocial/disruptive, and nonsocial/withdrawn playground behavior in preschool settings were also obtained. Results indicated that power-assertive mothers had preschoolers who engaged in more antisocial/disruptive behavior and who expected successful instrumental outcomes for hostile methods of resolving peer conflict. Preschoolers with such outcome expectations also participated in more antisocial playground behavior. Older preschoolers of inductive mothers engaged in more prosocial behavior and expected prosocial behavior to lead to both instrumental gains and enhanced relations with peers. Preschoolers who were more prosocial envisioned friendly-assertive strategies as leading to instrumental gains and, in the case of less nonsocial behavior, to enhanced relations with peers. Children's outcome expectations were also found to be different for older versus younger preschoolers. Evidence was also obtained suggesting that maternal discipline and outcome expectations make separate and independent contributions to children's social and aggressive play behavior.     

Call for papers

This study was designed to reveal the knowledge and skill sets that practicing day treatment and residential treatment EBD teachers view as important, and/or lacking, in novice EBD teachers, and to situate those findings within the larger contexts of teacher attrition and teacher preparation in special education. Primary results suggest that EBD teachers in day treatment and residential treatment centres believe knowledge of and implementation of best practices to be one of the most important prerequisites for effective practice in the EBD classroom, and one of the prerequisites most lacking by novice teachers. EBD teachers also indicated that knowledge of and appropriate use of behaviour management techniques was essential for effective practice, and also was reported to be lacking in novice teachers. In addition, EBD teachers reported a number of areas in which their teacher preparation programmes were perceived as lacking depth. Finally, certain personality attributes were identified as essential prerequisites for effective practice in the EBD classroom. Results are useful for teacher educators, teacher coaches, and school administrators.     

Environmental Hazards Education for Childbirth Educators

The purpose of this article is to educate childbirth educators about environmental hazards and provide resources. Hazardous chemicals have been found in cord blood, placenta, meconium, and breastmilk samples. These chemicals include commonly known hazards such as lead, mercury, and environmental tobacco smoke, as well as some pesticides, solvents, products containing chlorine, and other chemicals referred to as “persistent organic pollutants.” The fetus is particularly vulnerable to environmental chemicals that can disrupt the developmental process at critical times during gestation. Childbirth educators are encouraged to inform themselves in order to inform childbearing families to take preventive action and explore alternative behaviors to reduce exposure to environmental hazards.     

Self-regulated learning: the role of motivation,emotion, and use of learning strategies in students’ learning experiences in a self-paced online mathematics course

Enrollment in online remedial mathematics courses has increased in popularity in institutions of higher learning; however, students unskilled in self-regulated learning (SRL) find online remedial mathematics courses particularly challenging. We investigated the role of SRL, specifically motivation, emotion, and learning strategies, in students’ learning experiences in a remedial online mathematics course. With an online survey of 229 college students, we found that student motivation explained a small portion of variance in achievement; whereas student motivation and emotion explained a significant portion of variance in satisfaction. In addition, significant differences in motivation and emotion were found in passing and nonpassing students; however, learning strategies did not influence student achievement and satisfaction. Implications for teaching and learning in self-paced online remedial mathematics courses are discussed.
