Alternate Conceptions of Preservice Elementary Teachers: The Itakura Method     

Aaron D. Isabelle  Cornelis de Groot 《Journal of Science Teacher Education》2008,19(5):417-435

In this study, we determined the effectiveness of the inquiry-based Itakura method for mediating alternate conceptions of preservice elementary teachers (N = 38) in an integrated mathematics, science, and technology methods course. We investigated alternate conceptions in the expansion of solids due to heating. There was a significant increase in participants’ immediate learning gains after participating in the Itakura method. Retention data was gathered after 1, 2, and 3 months. After 3 months, retention levels dropped slightly, but not significantly. Responses revealed that the majority of the participants did not revert back to alternate conceptions after 3 months.  相似文献

Ground reaction forces and kinematics of plant leg position during instep kicking in male and female collegiate soccer players     

Orloff H  Sumida B  Chow J  Habibi L  Fujino A  Kramer B 《Sports biomechanics / International Society of Biomechanics in Sports》2008,7(2):238-247

The players' ability to achieve the greatest distance in kicking is determined by their efficiency in transferring kinetic energy from the body to the ball. The purpose of this study was to compare the kinetics and kinematics of the plant leg position between male and female collegiate soccer players during instep kicking. Twenty-three soccer players (11 males and 12 females) were filmed in both the sagittal and posterior views while performing a maximal instep kick. Plant leg kinetic data were also collected using an AMTI 1000 force platform. There were no significant differences between the sexes in plant leg position, but females had significantly greater trunk lean, plant leg angle, and medial-lateral ground reaction force than the males. Males showed higher vertical ground reaction forces at ball contact, but there were no significant differences in ball speed at take-off between the sexes. Ball speed at take-off was inversely related to peak anterior-posterior ground reaction force (-0.65). The anatomical differences between the sexes were reflected in greater trunk lean and lower leg angle in the females.  相似文献

Field Analysis and Interdisciplinary Science: Scientific Capital Exchange in Behavior Genetics     

Aaron L. Panofsky 《Minerva》2011,49(3):295-316

This paper uses Pierre Bourdieu’s field theory to develop tools for analyzing interdisciplinary scientific fields. Interdisciplinary fields are scientific spaces where no single form of scientific capital has a monopoly and therefore multiple forms of scientific capital constitute the structures and stakes of scientific competition. Scientists compete to accumulate and define forms of scientific capital and also to set the rates of exchange between them. The paper illustrates this framework by applying it to the interdisciplinary field of behavior genetics. Most behavior geneticists envision their participation in the field as a means to compete for scientific capital in other fields. However, the scientific capital of behavior genetics has different values for scientists attempting to deploy it in different neighboring fields. These values depend on situations in each field and the ways behavior genetics mediates relationships among them. The pattern of relationships of exchange helps explain the social hierarchy and several features of knowledge production within behavior genetics.  相似文献   

Can Cosmopolitanism Work Religiously? A Response to David T. Hansen     

Aaron J. Ghiloni 《Religious education (Chicago, Ill.)》2017,112(3):217-224

This response to David T. Hansen's 2016 plenary address to the Religious Education Association tests the viability of educational cosmopolitanism for religious education. Using a Deweyan methodology of understanding an idea through its consequences, Hansen's proposal is analyzed using dialogues with interreligious and Islamic pedagogies. The question is asked, Can Islam be cosmopolitan?  相似文献   

International Student Support Groups: Learning from Experienced Group Members and Leaders     

Nate Page  Derek Griner  Timothy B. Smith  Aaron P. Jackson  Klint Hobbs 《Journal of College Student Psychotherapy》2019,33(3):180-198

A multisite qualitative study investigated the experiences of six group leaders and 10 group members who participated in seven different university counseling center international student support groups. Analyses of interview data using hermeneutic interpretation resulted in nine major themes and 10 subthemes organized into four sections: (a) recruitment and group design, (b) experiences of group members, (c) experiences of group leaders, and (d) additional considerations.  相似文献   

Physiological responses and time-motion characteristics of various small-sided soccer games in youth players     

Hill-Haas SV  Dawson BT  Coutts AJ  Rowsell GJ 《Journal of sports sciences》2009,27(1):1-8

The aim of this study was to examine acute physiological responses and time-motion characteristics associated with three different small-sided soccer game formats in youth players. Sixteen male soccer players aged 16.3+/-0.6 years (mean+/-s) completed three variations of a small-sided game (i.e. 2 vs. 2, 4 vs. 4, and 6 vs. 6 players) in which heart rate, rating of perceived exertion (RPE), blood lactate concentration, and time-motion characteristics were recorded. The pitch size was altered to keep the relative pitch area per player consistent for each game format. The 2 vs. 2 games exhibited greater blood lactate, heart rate, and RPE responses compared with 4 vs. 4 and 6 vs. 6 games (P<0.05). The players travelled less (P<0.05) distance at speeds of 0-7 km.h(-1) in the 4 vs. 4 compared with the 2 vs. 2 games (1128+/-10 m and 1176+/-8 m, respectively). Average maximal sprint distances above 18 km.h(-1) were lower (P<0.05) in 2 vs. 2 than in 4 vs. 4 and 6 vs. 6 games (11.5+/-3.9 m, 15.3+/-5.5 m, and 19.4+/-5.9 m, respectively), and in 4 vs. 4 compared with 6 vs. 6 games. The results show that as small-sided game formats decrease in size and relative pitch area remains constant, overall physiological and perceptual workload increases.  相似文献
