Although Vygotskian principles involving the Zone of Proximal Development (ZPD) are hailed as tenets undergirding teaching and learning within a constructivist setting, these principals have not been implemented widely within school classrooms. Tharp and Gallimore, building on the notion that learning can be maximized when a teacher has a heightened awareness of a student's ZPD and stimulates new learning based upon this understanding, argue that true teaching is a matter of “assisting performance”. This study examines the efforts of one university instructor to assist the performance of her graduate students as they learned to teach, scaffold and support struggling readers. The findings suggest that the university instructor successfully assisted her students by providing supportive feedback, extending their learning and providing appropriate resources through ongoing Email correspondence and face‐to‐face meetings and tutoring sessions. Success was attributed to the instructor's extensive knowledge of supporting struggling readers, awareness of her students' ZPD's in relation to the context of their learning and her efforts to consistently provide appropriate and specific feedback through iterative dialogue.  相似文献

The purpose of this study was to determine which family child care providers seek training, which providers drop out of training, and the effects of training on the quality of care offered by providers. One-hundred thirty family child care providers in three communities who enrolled in Family-to-Family training participated in the study. A comparison group consisted of 112 regulated providers in those same communities who were not involved in the training program under investigation. Each provider was observed for 3 hrs, was interviewed, and completed questionnaires. Providers in training were observed prior to training and 6 months afterwards. Results revealed that providers who sought training were very similar to typical regulated providers. Providers who dropped out of training were less experienced and used fewer business and safety practices than providers who completed it. Training increased global quality in two out of three sites, but did not affect process quality. Of 95 providers, 18 made observable (as opposed to statistically significant) improvements in quality following training, and 9 decreased in quality. These data are interpreted with respect to family child care training policies and practices.  相似文献

In this study, we examined how learners developed scientific explanations about light with the assistance of various technology-based scaffolds. The study emphasis was on scaffolding processes of reflection and articulation. We used a content-neutral software program (Progress Portfolio) to create the instructional scaffolds. A qualitative research design was used to investigate two pairs of prospective teachers in a science content course in engineering. Our findings suggested that the computer-based scaffolds used in our study were useful to support articulation, reflection, and revision of explanations, when certain conditions were met. A major theme of our findings relates to interacting effects among learner characteristics, teacher coaching, software scaffolding design, and task characteristics. This material is based on work supported by the National Science Foundation under NSF REC 9980055, which was granted to the second author. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the National Science Foundation. The authors would like to acknowledge Joe Taylor for his role in the design and implementation of the study.  相似文献

OBJECTIVE: The aim of this study was to examine the trajectory of cases through four systems: child protection, law enforcement, the dependency courts, and the criminal courts. METHOD: This study focused on a county selected from a 41-county telephone survey conducted for the National Incidence Study of Child Abuse and Neglect (NIS-3). For this analysis prospective samples were drawn from law enforcement (n=225) and the county child protection (CPS) agency (n=225) and followed through in-depth case tracking across all agencies and through both the dependency and criminal court systems. RESULTS: The percentage of CPS cases opened in dependency court was similar to prior studies (29%), but the acceptance and prosecution rates were much higher--92% of the cases referred from CPS, including many cases of physical abuse. Compared to referrals from CPS to law enforcement (93%), few cases were referred from law enforcement to CPS (17%). Anecdotally, case referral patterns appeared to be influenced by communication patterns and mutual positive regard, regardless of the collaborative protocols in place. One of the most instructive findings was the degree of difficulty in tracking cases across organizations and the types of obstacles that impeded success. Disorganization was not an issue, rather internal structures set up to facilitate intra-organizational processing were the same structures that actually impeded cross-organizational case finding. CONCLUSIONS: It is not sufficient to rely on the existence of multi-disciplinary teams or Child Advocacy Centers to ensure collaboration. More attention to daily tasks and activities as well as the nature and quality of communication is warranted. On the technical side, use of common case identifiers on cases that are cross-referred is strongly recommended. Future studies should broaden the scope of inquiry to include the consequences of all case trajectories, rather than solely focusing on the justice system.  相似文献

The increased emphasis on school‐based programmes as part of initial teacher education has resulted in renewed efforts to forge more effective partnerships between higher education institutions and schools. The University of Bath has established a mentor development programme to ensure that subject mentors have an opportunity to examine ways to engage novice teachers in critical reflection about their practice while providing the support and challenge necessary to help them develop as teachers. This study is based on experienced mentors’ and their perspective on their work with novice teachers and it is a follow‐up to earlier research based on Daloz’ model (1986, Effective Teaching and Mentoring, San Francisco, Jossey Bass) of support and challenge. It examines an emerging mentoring pedagogy through which experienced mentors attempt to engage novice teachers in shaping their own vision of teaching. Three mentor profiles are discussed—the laissez‐faire, the collaborative and the imperial mentor.  相似文献

The purpose of this study was to investigate the nature of students’ responses to a cross‐cultural science unit entitled “Maintaining health.” The unit was designed to help students to build bridges between their traditional practices and beliefs and western science concepts. This paper reports students’ responses to a pre‐test and post‐test, and their reflections on their learning. The responses were analysed using the collateral learning model. There was evidence of parallel, dependent, and secured collateral learning. The implications for science teaching and for assessing science learning are discussed.  相似文献

Research Findings: Children's early academic achievement is supported by positive social and behavioral skills, and difficulties with these skills frequently gives way to underachievement. Social and behavioral problems often arise as a product of parent–child interactional patterns and environmental influences. Few studies have examined the role of a salient aspect of children's environments, community locale, in the relationship between parenting practices and child outcomes. Using a large, nationally representative sample, we examined whether preschool parenting practices and children's social-behavioral skills in kindergarten were related to geographic setting (rural vs. city, suburban, and town). Results indicated that rural children experienced greater difficulties with parent-reported externalizing behaviors. Furthermore, rural parents displayed less emotional support than parents in other settings. Preschool parenting behaviors were associated with social skills and behavior problems in kindergarten, as reported by both parents and teachers. Parents' emotional supportiveness was found to account for the relationship between geographic setting and parent-reported children's social skills, such that rural parents who provided less emotional support had children with lower social skills in kindergarten. Practice or Policy: Findings of this research indicate that rural children may face particular risk for behavioral issues and highlight the need for increased behavioral supports in rural communities. Moreover, our results suggest that interventions designed to promote parents' support of children's emotions may have particular utility for rural families.  相似文献

As an essential department at a higher education institution and an informal learning space, little is known about how academic libraries contribute to student learning on campus. The Olin Library sought to learn the role of library space in our users' learning. We surveyed users about their learning behaviors in a specific space prior to a scheduled renovation and then in the same space after. We wanted to determine how the renovation changed users' perceptions of their learning behaviors in that space.  相似文献
