Objects and Objectivity: The Evolution Controversy at the American Museum of Natural History, 1915–1928     

Julie Homchick 《Science & Education》2010,19(4-5):485-503

For the purpose of this essay, I examine how evolutionary theory was treated and responded to in the American Museum of Natural History’s Hall of the Age of Man during the early 1900s. Specifically, I examine how the curatorial work of the museum’s president, Henry Fairfield Osborn, relied on the purported use of objectivity as a means by which to communicate the validity of evolutionary theory through the objects in his exhibit. But objectivity represented a resource for anti-evolution critics as well. To show this, I likewise examine how the Baptist pastor, John Roach Straton, responded to Osborn’s objects and purported use of objectivity in the Hall of the Age of Man and how he himself attempted to establish a different type of objectivity through pluralistic approaches to theories of origins. Established as a common value, objectivity ceased to be a simple discriminator between scientists and non-scientists within the debate over evolution. While issues over the teaching of evolutionary theory during this period are already well known, I show here that the controversy over evolutionary theory was not only an issue within public schools during the early 1900s, but also within the museum as an institute of public education and how the rhetorical role of objects and space were critical components of argument for both evolutionists and creationists.  相似文献   

On my honor: creating space for thinking and living Girl Scouts differently in (post)colonial Hawai‘i     

Patricia Espiritu Halagao  Julie Kaomea 《Gender and education》2018,30(7):866-881

Girl Scouts aims to foster leadership by encouraging girls to discover themselves, make connections, and take action to make the world better. This paper chronicles the five-year journey of eight professional mothers of color who sought to provide their daughters with a space to ‘think and live differently’ as Girl Scouts and young women of color in (post)colonial Hawai‘i. Through questionnaires and a semi-structured focus group interview, mothers reflect on their original intentions to create a ‘safe space’ for their daughters to engage with the politics of gender, race, and class and to rethink, review, and rework their identities. Mothers’ reflections reveal success in creating safe spaces for the critical analysis of gender, but comparatively less success in critical analyses of race and class – a phenomenon that the mothers suggest may have been complicated by (1) the enduring myth of Hawai‘i as a multicultural paradise, (2) Girl Scouts’ assimilationist history, and (3) the mothers’ own relatively privileged positions.  相似文献   

Environmental education professional development for teachers: A study of the impact and influence of mentoring     

Julie Ernst  Deanna M. Erickson 《The Journal of environmental education》2018,49(5):357-374

Rivers2Lake helps teachers learn to provide watershed educational experiences for students through a summer institute followed by mentoring. Teacher focus groups were conducted to investigate the impact of mentoring, as well as toward understanding what was influential in bringing about those impacts. Mentoring impacted teachers in affective ways and helped them use what they learned at the institute. The influential nature of the mentoring may be due to the mentors providing a sense of accountability, personalized support, as well as encouragement of reflection and assistance with navigating barriers. Teachers also articulated qualities of effective mentors: invested, flexible, and responsive. With teachers varying in the degree to which they felt they could continue R2L implementation without the support of mentors, implications are discussed.  相似文献

Private Speech Moderates the Effects of Effortful Control on Emotionality     

Kimberly L. Day  Amy Neal  Julie C. Dunsmore 《Early education and development》2018,29(2):161-177

Research Findings: In addition to being a regulatory strategy, children’s private speech may enhance or interfere with their effortful control used to regulate emotion. The goal of the current study was to investigate whether children’s private speech during a selective attention task moderated the relations of their effortful control to their anger and sadness. The private speech of 156 preschoolers (age in months: M = 52.10, SD = 9.24, min = 36.20, max = 69.50) was transcribed and coded during a selective attention task. Effortful control was observed and reported by parents. Anger and sadness were reported by parents and observed in a frustration task. Children who used more inaudible muttering had higher levels of sadness. Effortful control interacted with private speech to explain anger. The negative relation of effortful control to anger was significant for children who used low and moderate but not high levels of task-irrelevant private speech. Practice or Policy: The presence of private speech, although it may support regulatory abilities within a task, may be an additional form of evaluation that might help teachers and caregivers decide how best to support children’s learning. These findings suggest that private speech can be used as an indicator of how well children use other regulatory abilities, such as effortful control.  相似文献   

Explicit Vocabulary Instruction in Kindergarten: Case Studies of Students With and Without Language Disorders     

Jacqueline M. Myers  Julie W. Ankrum 《Early Childhood Education Journal》2018,46(6):683-691

Research demonstrates that children can make more significant gains through explicit instruction of vocabulary than implicit instruction (Blachowicz and Fisher in Teaching vocabulary in all classrooms, Allyn & Bacon, Boston, MA, 2010; Dalton and Grisham in Read Teach 64(5):306–317, 2011). Effective explicit instruction often includes high quality conversations with teachers and peers (Towson et al. in J Early Interv 38(4):230–246, 2016; Wasik in Read Teach 63(8):621–633, 2010). Data for this study were collected from a larger study designed to explore students’ use of vocabulary words following explicit instruction with the words during an interactive read-aloud. A deeper microanalysis of student discussion, scaffolded by adults, was conducted. The transcribed student discussions, recorded during peer talk, were analyzed using NVivo 10 (QSR International in NVivo (version 10). NVivo qualitative data analysis software, QSR International, Doncaster, VIC, 2012) software. These case studies describe the vocabulary development of two children with diagnosed speech and language disorders and one child without a speech and language impairment.  相似文献   

Black Males in the Stadium: All ‘Bad Niggers’? French Literature,Sport and Masculinity from the 1920s to the 1950s     

Julie Gaucher 《国际体育史杂志》2013,30(9):1171-1186

In the first part of the twentieth century, ‘sports literature’ presented a new form of heroism departing from the traditional models of masculinity. The novels examined the stadiums, the boxing rings or the velodromes and noticed the existence of coloured sportsmen. Black boxers and athletes were considered as original models of manliness competing with the hegemonic masculinity, hitherto written in ‘white’. This essay intends to explore the French ‘sports novels’ published in the first part of the twentieth century. Relying on the history of masculinities and of gender, and on the methodological reflection of ‘race studies’, it examines the meeting between Black identity and athletic masculinity in literature. Thus this articles aims at showing how, through a series of stylistic, narrative and semiotic processes, the fiction essentialized the difference. Both fascinated and scared, the novels stigmatized Black sportsmen and endeavoured to analyse the alterity.  相似文献   

A Test of Schmidt's Schema Theory of Discrete Motor Skill Learning     

Julie F. Margolis  Robert W. Christina 《Research quarterly for exercise and sport》2013,84(4):474-483

Abstract

Schmidt's (1975) schema theory was tested with subjects who had to emit a rapid aiming response while wearing prism glasses. The glasses enabled them to view the target, but not their responding limb or the outcome of the movement. The problem was to determine the effect of (a) training with variable target practice, and (b) experiencing visual displacement information of the target, prior to training, on performance in transfer to a novel target distance. A 2 × 2 (type of practice × displacement information) factorial design was used, in which four groups of 15 male college subjects performed 60 training trials with verbal knowledge of results. The groups with variable target practice had less error on initial transfer to the novel target and throughout transfer than the groups with nonvariable target practice. No evidence was found to indicate that rate of learning for a novel target distance during transfer in the absence of KR is a positive function of the variability of target practice in training. Nor was any effect found for experiencing visual displacement information on performance in transfer.  相似文献   

Essential Conditions for Technology-Supported,Student-Centered Learning: An Analysis of Student Experiences With Math Out Loud Using the ISTE Standards for Students     

Mary Jo Dondlinger  Julie McLeod  Sheri Vasinda 《Journal of Research on Technology in Education》2016,48(4):258-273

This article explores links between student experiences with technology-rich mathematics instruction and the ISTE Standards for Students. Research methods applied constructivist grounded theory to analyze data from student interviews against the ISTE Standards for Students to identify which elements of the design of this learning environment seemed to support the attainment of both mathematics content objectives and the ISTE Standards for Students. Researchers then identify guiding principles for the effective design of technology-supported, student-centered learning environments based on analysis of the results. (Keywords: ISTE standards, mathematics education, student- created work, technology-rich learning)  相似文献   

Mothers' Beliefs about Feelings and Children's Emotional Understanding     

Julie C. Dunsmore  Michelle A. Karn 《Early education and development》2001,12(1):117-138

We revised Hyson and Lee's (1996) Caregiver's Beliefs about Feelings questionnaire for use with parents. One hundred and fifteen mothers of 4- to 6- year-old children completed the Parents' Beliefs about Feelings questionnaire (PBAF). We assessed emotional understanding of 60 of the children using Denham's (1986) measure. Factor analysis supported a 2-factor solution for the PBAF. The first subscale (Emotion Language) reflected mothers' belief in socializing emotion language. The second subscale (Developmental Beliefs) assessed mothers' belief that their children were not developmentally ready to control or talk about emotions. Mothers' Developmental Beliefs scores were positively related to mothers' negative emotional expressiveness. Mothers' Emotion Language scores were positively related to children's knowledge of emotion terms. Results may help educators design intervention programs to teach children emotional and social skills.  相似文献
