Facilitating learning in large lecture classes: testing the "teaching team" approach to peer learning     

Stanger-Hall KF  Lang S  Maas M 《CBE life sciences education》2010,9(4):489-503

We tested the effect of voluntary peer-facilitated study groups on student learning in large introductory biology lecture classes. The peer facilitators (preceptors) were trained as part of a Teaching Team (faculty, graduate assistants, and preceptors) by faculty and Learning Center staff. Each preceptor offered one weekly study group to all students in the class. All individual study groups were similar in that they applied active-learning strategies to the class material, but they differed in the actual topics or questions discussed, which were chosen by the individual study groups. Study group participation was correlated with reduced failing grades and course dropout rates in both semesters, and participants scored better on the final exam and earned higher course grades than nonparticipants. In the spring semester the higher scores were clearly due to a significant study group effect beyond ability (grade point average). In contrast, the fall study groups had a small but nonsignificant effect after accounting for student ability. We discuss the differences between the two semesters and offer suggestions on how to implement teaching teams to optimize learning outcomes, including student feedback on study groups.  相似文献   

The role of high school racial composition and opportunities to learn in students' STEM college participation          下载免费PDF全文

We analyze longitudinal data from students who spent their academic careers in North Carolina (NC) public secondary schools and attended NC public universities to investigate the importance of high school racial composition and opportunities to learn in secondary school for choosing a science, technology, engineering, and mathematics (STEM) major. We consider school racial composition and opportunities to learn as contexts that shape students' decisions regarding college majors. Results of cross‐classified hierarchical logistic models indicate that attending schools with predominantly White students is negatively associated with declaring a STEM major and with graduating with a STEM major irrespective of students' own race. The finding suggests that for students in North Carolina, attending racially isolated White high schools is related to a decrease in adolescents' participation in STEM during college.  相似文献   

Estimated maturity status and perceptions of adult autonomy support in youth soccer players

Abstract

In this study, we examined the relations between biological maturity status, body mass index, age, and perceptions of adult autonomy support in the context of youth soccer. A total of 70 female and 43 male soccer players, aged 9 – 15 years, completed three adult-specific versions (i.e. mother, father, coach) of the perceived autonomy support subscale from the Interpersonal Style Scale. The participants' percent predicted adult stature was used as an estimate of biological maturity status. Multiple linear regression analyses revealed that advanced maturity status in male players predicted lower perceptions of autonomy support from the coach. Maturity status was unrelated to perceptions of autonomy support from the coach in female soccer players, and paternal and maternal autonomy support in male and female players. Age and body mass index were unrelated to perceptions of adult (i.e. coach, mother, father) autonomy support in male and female players.  相似文献   

Agencies,educators, communities and wildfire: partnerships to enhance environmental education for youth     

Martha C. Monroe  Heidi L. Ballard  Annie Oxarart  Victoria E. Sturtevant  Pamela J. Jakes  Emily R. Evans 《Environmental Education Research》2016,22(8):1098-1114

We studied seven programs that engage youth from 10 to 18 years old in wildfire risk reduction in their communities in the United States through in-depth interviews to examine the nature and role of community-school partnerships in resource-focused environmental education. While the programs use a variety of strategies, from Scout badge to summer school, they exhibit several common dimensions: they all engage youth in community projects; they all arise from partnerships between resource agencies, community organizations, and educators; they all began when people familiar with both wildfire and youth education saw an opportunity to improve the community and educate youth through action; and all partners are able to contribute to the common program yet retain their individual identity as they meet their own mission-based goals. We use themes and quotes to illustrate these common dimensions for establishing community-school partnerships that could build action competence through environment-based education projects.  相似文献   

A Two-State Study of Family Child Care Engagement in Quality Rating and Improvement Systems: A Mixed-Methods Analysis     

Rena Hallam  Alison Hooper  Kaitlin Bargreen  Martha Buell  Myae Han 《Early education and development》2017,28(6):669-683

ABSTRACT

Research Findings. The current study is a mixed-methods investigation of family child care provider participation in voluntary Quality Rating and Improvement Systems (QRIS) in 2 states. Study 1 is an analysis of matched QRIS and child care licensing administrative data extracted from both states in May, 2014. Poverty and population density variables were added to the dataset by aligning U.S. Census data and Rural Urban Commuting Area codes (RUCA) to the matched state child care data. Participation patterns differed in the 2 states relative to provider characteristics (subsidy receipt, years licensed, and location). Study 2 consists of focus groups with participating (n = 22) and non-participating (n = 19) providers. Professionalism and financial incentives emerged as significant in attracting family child care providers to QRIS. Although family child care providers identified several clear benefits to QRIS, many more challenges emerged that negatively impact their participation. Practice or Policy. As most states are employing a QRIS framework to integrate quality improvement efforts, perspectives from this sector of early care and education are often overlooked. Study findings suggest that QRIS can be more responsive and effective with family child care providers if more consideration of their unique features are considered in systems design and implementation.  相似文献   

The expositive discourse as pedagogical discourse: studying recontextualization in the production of a science museum exhibition     

Martha Marandino 《Cultural Studies of Science Education》2016,11(2):481-514

In this paper I report on the sociological and educational particulars of The Biodiscovery Space exhibition of the Life Museum of the Oswaldo Cruz Foundation in Rio de Janeiro, Brazil, using Basil Bernstein’s framework of pedagogic discourse and recontextualization. Data for analysis was obtained from interviews with the exhibition developers, field observations of museum visitors and analysis of exhibition documents. Using the ideas of power, classification and framework, among others, I analyzed the recontextualization process of the production of expositive discourse. Thus, working with Bernstein’s idea of classification, I explain the relationship between the discourses of the science of biology, history of science, museology, education, and communication in order to produce an expositive discourse. I also make explicit how agents of the Official Recontextualization Field of the Museum and the Pedagogic Recontextualization Field “....of the Museum determine partly the final expositive discourse of an exhibition”. Using the idea of a pedagogic discourse framework, I discuss how the constraints imposed by objects and texts in exhibitions help to create a specific manner of visitor interaction with these elements, “even if they have some autonomy”. Considerations about the audience and the intended process of acquisition are presented, when I discuss the control strategies of the exhibition. I propose that the Biodiscovery Space exhibit has a visible pedagogy. Finally, using the collected data I discuss the power tensions created in the production of expositive discourse showing how distributive, recontextualization and evaluation rules work in the context of exhibitions. The study of the dynamics in forming the expositive discourse using Bernstein’s framework reveals the individuals and institutions, the selection criteria, the negotiations and the power relations involved. It has the potential to assist both educators and researchers in the museum education field, as well as designers to understand the teaching and learning processes that occur during a visit and to establish relevant criteria to evaluate quality to best produce exhibitions in science museums.  相似文献   

The developmental consequence of different patterns of maltreatment   总被引：1，自引：0，他引：1  

Byron Egeland Ph.D.  L. Alan Sroufe Ph.D.  Martha Erickson M.A. 《Child abuse & neglect》1983,7(4):459-469

From a longitudinal study of 267 high risk families, four different patterns of maltreatment were identified. The mothers have been tested, interviewed and observed in a number of situations starting during the last trimester of pregnancy and continuing at regularly scheduled intervals through the preschool period. The four maltreatment groups were: physical abuse; hostile/verbally abusive; psychologically unavailable; and neglecting. A control group of mothers who provided adequate care was selected from the remaining high risk sample. In an earlier follow-up, among the maltreated children a disproportionately large number of infants were found to be anxiously attached to their mothers at 12 and 18 months, and their performance in a problem-solving situation at age two was poor. In the current follow-up, the children were videotaped at 42 months in a "barrier box" and teaching situation, and at 56 months they were observed in a preschool situation. The physically abused children were distractible, lacked persistence, ego control and enthusiasm, and experienced considerable negative emotion. The children whose mothers were psychologically unavailable showed marked increases in maladaptive patterns of functioning from infancy through preschool. As expected, they were avoidant of their mother, angry, noncompliant, and they were highly dependent. The neglected children had the most difficulty pulling themselves together to deal with various tasks. They lacked self-esteem and agency necessary to cope with their environment.  相似文献   

Differences between WISC‐R and WISC‐III performance scale among children with ADHD

Reviews involving the Wechsler Scales for children suggest that Full Scale IQ scores on the Wechsler Intelligence Scale for Children, Third Edition, average 5 to 6 points lower than scores on the second edition of the scale [WISC‐R, Wechsler, D. (1974). Zimmerman & Woo‐Sam, 1997], with the differences distributed disproportionately over subtests, i.e., with larger discrepancies found within the Performance Scale (Wechsler, 1991). Changes on the revised subtests of the WISC‐III Performance Scale may place children with ADHD at a disadvantage compared to their performance on analogous WISC‐R subtests. We examined IQ test performance in 122 unmedicated children with ADHD (61 given the WISC‐R, 61 given the WISC‐III), and 46 children from a healthy, comparison group (23 given the WISC‐R, 23 given the WISC‐III). The ADHD and comparison group samples were matched for sex and for Verbal IQ between WISC‐R and WISC‐III. Children with ADHD had significantly lower Performance IQ on WISC‐III compared to the WISC‐R, with the Picture Arrangement subtest showing the most significant difference. In contrast, there were no significant differences between the WISC‐R and WISC‐III cohorts on Performance IQ or any Performance subtests among the comparison group. These findings highlight the importance of examining the comparability of ability test revisions among clinical and non‐clinical populations, and will be especially salient when the WISC‐III is revised. © 2003 Wiley Periodicals, Inc.

A comparison of personality attributes of science teachers and medical technologists     

M. U. Kazi  Martha K. Piper 《科学教学研究杂志》1983,20(6):529-536

Undergraduate students who major in science make diverse career choices. Two such career choices are medical technologists and science teachers. One possible reason for science majors selecting different career choices might be attributed to varied personality dimensions. The purpose of this study was to identify a set of personality attributes that distinguish practicing medical technologists from practicing science teachers. The subjects of this study consisted of 83 medical technologists and 57 science teachers. Eysenck Personality (EPI) was utilized to investigate the personality attributes of subjects in terms of Eysenck's personality variable of Extroversion-Introversion and Neuroticism-Stability. Vocational Preference Inventory was utilized to investigate the vocational personality profile of subjects in terms of Holland's classification of occupations and work environment. Data with EPI revealed that there was no significant difference between medical technologists and science teachers with respect to Eysenck's personality variable of extroversion. However, there was found a significant difference between the two groups with respect to Eysenck's personality variable of neuroticism. Data with VPI revealed that there was no significant difference between medical technologists and science teachers with respect to Eysenck's personality variable of extroversion. Both the groups were characterized by the personality profile of IAS (Intellectual-Artistic-Social). This profile was different from that required earlier in literature.  相似文献   

Deaf and hearing students' morphological knowledge applied to printed English   总被引：2，自引：0，他引：2  

Gaustad MG  Kelly RR  Payne JA  Lylak E 《American annals of the deaf》2002,147(5):5-21

The study examined the ability of deaf and hearing students at the college and middle school levels to discern and apply knowledge of printed word morphology. There were 70 deaf and 58 hearing participants. A two-part paper-and-pencil test of morphological knowledge examined subjects' ability to (a) perceive segmentation of morphemes within printed words and (b) recognize meanings associated with various printed morphemes. The hearing college students performed best on every dependent measure of the two-part test. The deaf college students scored significantly lower than the hearing college students but similarly to the hearing middle school students. Deaf middle school students consistently scored the lowest on both parts of the test. While all students' performance declined as the difficulty of the morphemic content increased within both tasks, the decline was greatest among middle school deaf students. Although segmentation and semantic analysis skills necessary to morphographic decoding were apparent in the deaf students, their mastery levels fell significantly below those of the hearing subjects.  相似文献
