In an effort to understand the role of interhemispheric transfer in numerical development, we investigated the relationship between children's developing knowledge of numbers and the integrity of their white matter connections between the cerebral hemispheres (the corpus callosum). We used diffusion tensor imaging (DTI) tractography analyses to test the link between the development of the corpus callosum and performance on symbolic and non-symbolic numerical judgment tasks. We were especially interested in the interhemispheric connections of parietal cortex in 6-year-old children, because regions of parietal cortex have been implicated in the development of numerical skills by several prior studies. Our results revealed significant structural differences between children and adults in the fibers of the corpus callosum connecting the left and right parietal lobes. Importantly, these structural differences were predictive of individual differences among children in performance on numerical judgment tasks: children with poor numerical performance relative to their peers exhibited reduced white matter coherence in the fibers passing through the isthmus of the corpus callosum, which connects the parietal hemispheres.  相似文献

This study considers how institutional histories of admitting women are associated with present college experiences, and uses data from the Wabash National Study of Liberal Arts Education to compare the experiences of women at women’s colleges or former women’s colleges to those of women at former men’s colleges and colleges that have always been coeducational. Results indicate that women attending former men’s colleges and colleges that have always been coeducational seem to experience similar or greater frequency and quality of student–faculty interaction and exposure to good teaching practices, compared to women attending women’s or former women’s colleges. Results also suggest that considering the gender enrollment histories of colleges and universities may provide valuable context for evaluating the experiences of women at women’s colleges and coeducational institutions.  相似文献

Designed-based research principles guided the study of 51 secondary-science teachers in the second year of a 3-year professional development project. The project entailed the creation of student-centered, inquiry-based, science, video games. A professional development model appropriate for infusing innovative technologies into standards-based curricula was employed to determine how science teacher’s attitudes and efficacy where impacted while designing science-based video games. The study’s mixed-method design ascertained teacher efficacy on five factors (General computer use, Science Learning, Inquiry Teaching and Learning, Synchronous chat/text, and Playing Video Games) related to technology and gaming using a web-based survey). Qualitative data in the form of online blog posts was gathered during the project to assist in the triangulation and assessment of teacher efficacy. Data analyses consisted of an Analysis of Variance and serial coding of teacher reflective responses. Results indicated participants who used computers daily have higher efficacy while using inquiry-based teaching methods and science teaching and learning. Additional emergent findings revealed possible motivating factors for efficacy. This professional development project was focused on inquiry as a pedagogical strategy, standard-based science learning as means to develop content knowledge, and creating video games as technological knowledge. The project was consistent with the Technological Pedagogical Content Knowledge (TPCK) framework where overlapping circles of the three components indicates development of an integrated understanding of the suggested relationships. Findings provide suggestions for development of standards-based science education software, its integration into the curriculum and, strategies for implementing technology into teaching practices.  相似文献

Findings are presented from the first randomized control trial of the effects of encouraging symbolic gesture (or “baby sign”) on infant language, following 40 infants from age 8 months to 20 months. Half of the mothers were trained to model a target set of gestures to their infants. Frequent measures were taken of infant language development and dyadic interactions were scrutinized to assess mind‐mindedness. Infants exposed to gesture did not differ from control conditions on language outcomes; thus, no support was found for previous claims that encouraging gesturing with infants accelerates linguistic development. Microgenetic analysis revealed mothers in the gesture training conditions were more responsive to their infants' nonverbal cues and encouraged more independent action by their infant.  相似文献

A stress management program was evaluated in sixth-grade classes of an urban public and a suburban parochial school. Sample 1, from the urban public school, and Sample 2, from the suburban parochial school, received pre- and posttests. Sample 3, from the suburban parochial school, was divided into pretest-only and posttest-only groups. Six self-esteem and 1 each stress and social-skills children's self-ratings and 1 each teachers' ratings of children's overall stress management and stress measures were used. All 10 measures showed improvement in the Samples 1 and 2 independently. Findings in Sample 2 replicated the positive effects in Sample 1. In both sixth-grade classes, children's stress level (self- and teachers' ratings), children's social skills and self-esteem self-ratings, and teachers' ratings of children's stress management skills improved significantly. Sample 3 posttest-only group scores did not differ significantly from the posttest scores of Sample 1 and 2 children. Rival hypotheses (e.g., history, maturation, testing) appeared implausible. Results support using skills-oriented stress management programs in regular grade school classes.  相似文献

Much literature has been devoted to theoretical explanations of the learning processes of older adults and to the methods of teaching best utilized in older populations. However, there has been less focus on the education of older adults who reside in assisted and independent living communities (AICs), especially with regards to information and communication technology (ICT) education. The purpose of this study is to determine whether participants' attitudes and views towards computers and the Internet are affected as a result of participating in an eight-week training program designed to enhance computer and Internet use among older adults in such communities. Specifically, we examine if ICT education specially designed for AIC residents results in more positive attitudes towards ICTs and a perceived decrease in factors that may limit or prevent computer and Internet use. We discuss the implications of these results for enhancing the quality of life for older adults in AICs and make recommendations for those seeking to decrease digital inequality among older adults in these communities through their own ICT classes.  相似文献

This study replicates research on the efficacy of a repeated reading intervention with word-level instruction for students in Grades 2 and 3 with low to moderate fluency skills, examines differences between treatment implementers, and tests unique contributions of treatment-related variables on outcomes. Students from 13 schools were randomly assigned to dyads; dyads were randomly assigned to treatment or control conditions. Schools were matched into treatment implementer groups (teachers or paraeducators) at study onset. Tutoring occurred during school hours for 15 weeks (M = 25.5 hr). Multilevel model results showed treatment students (n = 98) gained more than controls (n = 104) on measures of letter-sound knowledge (d = .41), fluency (d = .37–.38), and comprehension (d = .30–.31); students tutored by teachers gained more than their paraeducator-tutored peers on word reading and fluency. Finally, dyads tutored with greater fidelity gained more in word reading and fluency; dyads that read more complex words in their texts gained less on letter-sounds, fluency, and comprehension.  相似文献

This study examines the nature of teacher participation in the context of a video club. Video clubs are professional development meetings in which teachers watch and discuss excerpts of video from their classrooms. In this study, I adopt a situative perspective to examine how teachers develop in their participation to accomplish the goals of the video club. In particular, I examine the roles participants play and explore teachers' participation in four roles that correspond with key goals of the video club. Analysis revealed that teachers' participation shifted in qualitatively different ways over time, with the teachers coming to prompt the group to discuss student mathematical thinking, to propose a variety of interpretations of student ideas, to build on one another's ideas, and to challenge one another's thinking in order to advance the group's conversations. This analysis suggests that the group learned how to participate in roles central to accomplishing the goals of the video club. Studying teacher learning through a lens of participation provides insight into the ways in which teachers coordinate themselves to engage with the goals of professional development and has implications for designing professional development that helps teachers develop practices for teaching mathematics for understanding.  相似文献

This paper presents a literature review regarding language abilities of children with Down syndrome and presents a case study concerning the effectiveness of using Total Communication with a young child with Down syndrome. The prevalence of expressive language delays in children with Down syndrome highlights the need to develop early interventions to promote language development. The existing literature on the usefulness of Total Communication as an intervention method with children and adults with special needs is documented and a rationale for the use of Total Communication with children with Down syndrome is presented. In the case study, a single subject simultaneous treatment design was used which involved introducing 20 words during free play (10 oral and 10 Total Communication), which were matched on phonetic complexity and reinforcement value. Results indicated that comprehension was not differentially affected by the type of communication approach used. However, expressively the child was able to use manual signs many months before any understandable words were produced. The use of manual signs did not inhibit use of speech. The results of this case study suggest that the early use of Total Communication can be an effective transitional mode of communication for at least some children with Down syndrome. Further research is needed to explore individual differences between children with Down syndrome and to identify factors that predict those children who benefit most from the use of Total Communication.  相似文献
