Previous research has highlighted the positive effect that different warm-up protocols have on golf performance (e.g. Sorbie et al., 2016; Tilley & Macfarlane, 2012) with the design of warm-ups and programmes targeting and improving golf performance through the activation and development of specific muscle groups. This study aimed to examine the acute effects of two warm-up protocols on golf drive performance in comparison to a control condition. Using a randomised counterbalanced design over three testing sessions, twenty-three highly skilled golfers completed the control, dynamic and resistance-band warm-up conditions. Following each condition, a GC2 launch monitor was used to record ball velocity and other launch parameters of ten shots hit with the participants’ own driver. A repeated-measures ANOVA found significant increases in ball velocity (η_p² = .217) between the control and both the dynamic and resistance-band warm-up conditions but no difference between these latter two, and a reduction in launch angle between control and dynamic conditions. The use of either a dynamic stretching or resistance-band warm-up can have acute benefits on ball velocity but golfers should liaise with a PGA Professional golf coach to effectively integrate this into their golf driving performance.  相似文献

Children's ideas about evaporation     

Terry Russell  Wynne Harlen  Dot Watt 《International Journal of Science Education》2013,35(5):566-576

This article reports on research conducted as part of the Primary Science Processes and Concept Exploration (space) Project. The background to, and orientation of, space is briefly described.

Classroom‐based research into children's thinking about evaporation is reported. This work was conducted in close collaboration with teachers of the 5‐11 years age range with the intention of establishing the viability of the techniques for eliciting ideas and managing subsequent interventions within classrooms.

Children's thinking in relation to three main evaporation phenomena are discussed. Ideas about evaporation were categorized by reference to notions of conservation, change of location and change of form of the water.  相似文献   

Does STES‐Oriented Science Education Promote 10th‐Grade Students’ Decision‐Making Capability?     

Tami Levy Nahum  David Ben‐Chaim  Ibtesam Azaiza  Orit Herskovitz 《International Journal of Science Education》2013,35(10):1315-1336

Today’s society is continuously coping with sustainability‐related complex issues in the Science‐Technology‐Environment‐Society (STES) interfaces. In those contexts, the need and relevance of the development of students’ higher‐order cognitive skills (HOCS) such as question‐asking, critical‐thinking, problem‐solving and decision‐making capabilities within science teaching have been argued by several science educators for decades. Three main objectives guided this study: (1) to establish “base lines” for HOCS capabilities of 10th grade students (n = 264) in the Israeli educational system; (2) to delineate within this population, two different groups with respect to their decision‐making capability, science‐oriented (n = 142) and non‐science (n = 122) students, Groups A and B, respectively; and (3) to assess the pre‐post development/change of students’ decision‐making capabilities via STES‐oriented HOCS‐promoting curricular modules entitled Science, Technology and Environment in Modern Society (STEMS). A specially developed and validated decision‐making questionnaire was used for obtaining a research‐based response to the guiding research questions. Our findings suggest that a long‐term persistent application of purposed decision‐making, promoting teaching strategies, is needed in order to succeed in affecting, positively, high‐school students’ decision‐making ability. The need for science teachers’ involvement in the development of their students’ HOCS capabilities is thus apparent.  相似文献   

Improving Risk Education in Grades 6–12: A Needs Assessment of Michigan,Ohio, and Wisconsin Science Teachers     

R. Ben Peyton 《The Journal of environmental education》2013,44(2):46-54

Abstract

If formal educators are to play a role in preparing future citizens for making decisions about health and environmental risks, then they must be willing and able to incorporate risk education. This article presents 10 goals for risk education. It also describes current risk education practices, future interests, and perceived barriers to risk education of Michigan, Ohio, and Wisconsin Grades 6–12 science teachers. Data were collected through a mail questionnaire (1,336 surveys were returned, adjusted return rate = 80%) and in-depth telephone interviews (completed with 45 teachers, return rate = 90%). Many teachers had covered some aspect of risk education and were interested in enhancing their efforts. Results also suggest that teachers need to be made aware of risk education resources and provided with training, particularly regarding psychological influences on risk decisions.  相似文献   

REPORT OF BIBLICAL INSTRUCTORS CONFERENCE*     

Meir Ben‐Horin 《Religious education (Chicago, Ill.)》2013,108(5):470-471

This article examines the psychoanalytic concepts of object-relations theorist Christopher Bollas, applying them to a view of the Bible as “transformational object.” Emphasizing the connection between psychological process and religious experience, this article suggests that each person's innate ability to choose and use objects is a key factor in their ability to appropriate the Bible for constructive use. By offering religious objects with psychological awareness, religious educators may come to appreciate that silence, empathy, and open-ended lesson plans are important incubators of transformation; and that aggression has a potentially positive role in the healthy development of worship communities.  相似文献
