We study the relationship between parental job loss and children's academic achievement using data on job loss and grade retention from the 1996, 2001, and 2004 panels of the Survey of Income and Program Participation. We find that a parental job loss increases the probability of children's grade retention by 0.8 percentage points, or around 15%. After conditioning on child fixed effects, there is no evidence of significantly increased grade retention prior to the job loss, suggesting a causal link running from the parental employment shock to children's academic difficulties.  相似文献

As more faculty members utilize student-centered methods, we should also expect to see an increase in graduate teaching assistants (TAs) who are asked to co-teach these classes. However, little is written about the challenges TAs face and the adjustments they make when teaching student-centered courses. This study examined a student-centered course taught by the hevruta method, a dyadic approach that emphasizes text-based student discussions. Although students reported significant learning gains, both they and TAs had to negotiate new instructional roles. Based on student and TA feedback, strategies are presented to facilitate effective student learning in a student-centered course co-taught by TAs.  相似文献

This study investigated the effectiveness of an instructional program (schema-based instruction, SBI) designed to teach 7th graders how to comprehend and solve proportion problems involving ratios/rates, scale drawings, and percents. The SBI program emphasized the underlying mathematical structure of problems via schematic diagrams, focused on a 4-step procedure to support and monitor problem solving, and addressed the flexible use of alternative solution strategies based on the problem situation. Blocking by teacher at three middle schools, the authors randomly assigned the 21 classrooms to one of two conditions: SBI and control. Classroom teachers provided the instruction. Results of multilevel modeling used to test for treatment effects after accounting for pretests and other characteristics (gender, ethnicity) revealed the direct effects of SBI on mathematical problem solving at posttest. However, the improved problem solving skills were not maintained a month later when SBI was no longer in effect nor did the skills transfer to solving problems in new domain-level content.  相似文献

Both classroom instruction and lexical database development stand to benefit from applied research on sign language, which takes into consideration American Sign Language rules, pedagogical issues, and teacher characteristics. In this study of technical science signs, teachers' experience with signing and, especially, knowledge of content, were found to be essential for the identification of signs appropriate for instruction. The results of this study also indicate a need for a systematic approach to examine both sign selection and its impact on learning by deaf students. Recommendations are made for the development of lexical databases and areas of research for optimizing the use of sign language in instruction.  相似文献

Despite the expansion of Deaf people's use of communication technology little is published about how they use electronic communication in their social and working lives and the implications for their concepts of identity and community. Australia is an ideal research base because the use of a range of technologies is widespread there. To gain access to a wide age range of people who identify as Deaf, members of the national organization, the Australian Association of the Deaf, were surveyed by mail. Results showed that Short Message Service (SMS), telephone typewriters (TTY), voice/TTY relay services, fax, and e-mail were used regularly. Deaf users are discerning of the purposes for which they use each method: SMS for social and personal interactions, TTY for longer communications and (via the relay service) with people and services without TTYs, fax for business and social contact, and computers for personal and business e-mails as well as Web browsing, accessing chat rooms, word processing, games, and study.  相似文献

Predictors of depressive symptoms among foster caregivers   总被引:1,自引:0,他引:1  
OBJECTIVES: The main purposes of this study were to determine (1) the prevalence of depressive symptoms among foster caregivers, (2) the social-demographics, risk factors, and social support predicting depressive symptoms, and (3) whether social support buffered the effects of the risk factors in the Illinois Foster Caregivers Study. METHOD: Telephone interviews were used to collect data from a sample of 189 foster caregivers in the State of Illinois. Interviewers pretested the survey instrument, which included valid and reliable instruments on depressive symptoms and adult report of childhood maltreatment, an important risk factor for depression. Multivariate ordered logistic regression models were estimated. RESULTS: The foster caregivers exhibited few depressive symptoms, with only one respondent scoring in the clinical range. Contrary to past research on the general population, caregivers reporting higher income were at an increased risk of exhibiting depressive symptoms. The three risk factors-experiencing less than excellent or very good health, childhood maltreatment, and insufficient time to carry out responsibilities-were related to higher levels of depressive symptoms. Foster caregivers who perceived their support group as helpful had a decreased risk of reporting depressive symptoms. We found no evidence that social support buffered the effects of the risk factors. CONCLUSIONS: The results indicate that foster caregivers were adequately screened for depression, but suggest that assessing and providing assistance for health problems, trauma from childhood maltreatment, and insufficient time to meet responsibilities might decrease depressive symptoms. Facilitating and enhancing the helpfulness of foster caregiver support groups also might decrease development of depressive symptoms.  相似文献

Current government policy in the UK places teachers of all subject areas under pressure to embed ICT into their pedagogic practice to improve teaching and learning. This article attempts to compare that policy with the situated reality of a small number of Modern Foreign Language teachers striving to comply. The voices of four teachers are presented as they began to embed the use of ICT (primarily their newly acquired Interactive Whiteboards) into their existing classroom approach. The story of their developing practice is examined for signs of transformation; the complexity of a real situation is thus contrasted with a simplified ideal. By means of this investigation, examples of sophisticated pedagogical thinking are explored to demonstrate that it is perhaps not so easy to transform the learning process, with or without ICT.

La politique actuelle du gouvernement du Royaume‐Uni exerce une pression sur les enseignants de toutes matières pour qu'ils intègrent les technologies d'information et de communication dans leurs pratiques pédagogiques afin d'améliorer l'enseignement et l'apprentissage. Cet article essaye de comparer cette politique avec la réalité contextualisée d'un petit nombre de professeurs de langues étrangères qui font leur possible pour s'y conformer. Les voix de quatre enseignants y sont présentées alors qu'ils commençaient à intégrer l'informatique (et en particulier leurs tableaux interactifs récemment acquis) dans leur approche pédagogique actuelle. L'histoire du changement de leurs pratiques est remise en question pour trouver des indications de transformation. La complexité d'une situation réelle peut alors être mise en contraste avec une idée simplifiée. De par cette étude, on peut examiner des exemples de la réflexion pédagogique développée pour montrer que ce n'est pas tellement facile de transformer les méthodes d'apprentissage, avec ou sans l'outil informatique.

Die Gegenwärtige Regierungspolitik in Großbritannien setzt Lehrkräfte aller Schulfächer unter Druck, moderne Informationstechniken in ihre pädagogische Praxis einzubeziehen, um den Unterricht und den Lernprozess zu verbessern. Dieser Beitrag versucht, diese Politik mit der realen Situation einer kleinen Anzahl von SprachlehrerInnen zu vergleichen, die sich bemühen, den Anordnungen nachzukommen. Die Stimmen von vier Lehrkräften werden vorgelegt, die damit begonnen haben, Informations‐ und Kommunikationstechnologie (hauptsächlich ihre neu erworbenen interactive whiteboards (interaktive Tafeln)) in ihre gegenwärtige Unterrichtsmethode einzubeziehen. Es wird untersucht, welche Veränderungen es bei zunehmender Praxis gibt. Die Vielschichtigkeit einer realen Situation wird somit dem vereinfachten Idealfall gegenübergestellt. Mittels dieser Untersuchung werden Beispiele hochentwickelten pädagogischen Denkens erforscht und dazu verwendet, um zu zeigen, dass es doch nicht so einfach ist, den Lernprozess zu verändern—mit oder ohne ICT.

La política actuel del gobierno del Reino Unido sitúa a los profesores de todos los departamentos bajo la presión de arraigar ICT en la práctica de su pedagogía para mejorar la enseñanza y el aprendizaje. Este artículo intenta comparar esa política con la realidad de un pequeño número de profesores de idiomas extranjeros que se esfuerza por llevarla a cabo. La voz de cuatro profesores nos presenta como empoezaron a arraigar el uso de ICT (primeramente con la reciente adquisición de los Whiteboards Interactivos) como enfoque en sus clases actuales. La historia de su práctica en desarrollo está acompañada de indicios de cambios. Por eso la complejidad de una situación real se contrasta con un ideal más simplificado. Por medio de esta investigación, se exploran ejemplos de pensamiento pedagógico sofisticado para demostrar que quizás no sea tan fácil transformar el proceso de aprendizaje, con o sin ICT.  相似文献

Genome Consortium for Active Teaching: meeting the goals of BIO2010   总被引:2,自引:2,他引:0  
The Genome Consortium for Active Teaching (GCAT) facilitates the use of modern genomics methods in undergraduate education. Initially focused on microarray technology, but with an eye toward diversification, GCAT is a community working to improve the education of tomorrow's life science professionals. GCAT participants have access to affordable microarrays, microarray scanners, free software for data analysis, and faculty workshops. Microarrays provided by GCAT have been used by 141 faculty on 134 campuses, including 21 faculty that serve large numbers of underrepresented minority students. An estimated 9480 undergraduates a year will have access to microarrays by 2009 as a direct result of GCAT faculty workshops. Gains for students include significantly improved comprehension of topics in functional genomics and increased interest in research. Faculty reported improved access to new technology and gains in understanding thanks to their involvement with GCAT. GCAT's network of supportive colleagues encourages faculty to explore genomics through student research and to learn a new and complex method with their undergraduates. GCAT is meeting important goals of BIO2010 by making research methods accessible to undergraduates, training faculty in genomics and bioinformatics, integrating mathematics into the biology curriculum, and increasing participation by underrepresented minority students.  相似文献
