Service-learning is a teaching strategy designed to provide learners opportunities to transfer theory to practice in an authentic environment while concurrently meeting genuine needs in the community. The reciprocal nature of service-learning differentiates this pedagogy from other learning venues including field experiences, internships, and student teaching. Recently the interest surrounding, as well as the utilization of service-learning, has grown in numerous academic disciplines including physical education teacher education (PETE). PETE research investigating the impact of service-learning in regards to student and community outcomes is also emerging. The purpose of this article is to provide a review of the current PETE service-learning literature. Components of the review include examination of theoretical frameworks, exploration of the impact of service-learning on PETE students and community participants, and recommendations for practice and future research.  相似文献

When translating word problems into equations, a common error consists of using the same letter to refer to two different quantities. This error, called multiple referents for the unknown, can be connected to the existence of deictic or indexical expressions within the problem statement. This paper aims to analyse the influence of indexical expressions on the incidence of the multiple referents for the unknown error. Results from a quantitative study with 117 Spanish secondary students show a significantly higher number of such type of error when the problem statement contains indexical expressions. The analysis of students’ performances in subsequent interviews indicates that this error may be due to the fragmented reading of statements.  相似文献

Resumen

En el presente trabajo se analiza la relación existente entre el concepto de estrategias de aprendizaje y de habilidades metacognitivas en el marco de un modelo explicativo basado en la mediación cognitiva. Posteriormente se revisan los métodos instruccionales que se han mostrado más eficaces en la instauración de macroestrategias entre los estudiantes, y se describe de manera pormenorizada un sistema de autointerrogación metacognitiva, el procedimiento metacognitive de enseñanza-aprendizaje (promete-a). La aplicación de promete-a, en un estudio piloto, a 16 profesores de distintos niveles educativos no-universitarios, ha demostrado tener una incidencia positiva en la planificación, monitorización y evaluación de los procesos cognitivos implicados en la tarea ae preparation de sesiones de clase.  相似文献

Resumen

El presente artículo tiene como objetivo analizar los procesos de codificación y almacenamiento en tareas que implican el sistema de la MCP. Con este fin, hemos utilizado material verbal y hemos manipulado el grado de similitud táctil y fonética de los estímulos para estudiar su efecto en la retención a corto plazo. Los resultados de los dos experimentos indican, por un lado, que los ciegos se sirven de formatos de naturaleza diferente (táctil-fonémica) para mantener la información a corto plazo y, por otro lado, que incrementan su capacidad de almacenamiento con la edad.  相似文献

ABSTRACT

Strategies based memory training programs are widely used to enhance the cognitive abilities of the elderly. Participants in these training programs are usually people whose mental abilities remain intact. Occasionally, people with cognitive impairment also participate. The aim of this study was to test if memory training designed specifically for healthy people is effective in people with severe memory impairment. We carried out a 10-year retrospective case-control study with Rivermead Behavioural Memory Test (RBMT) and memory complaint measures obtained pre-post training. The case group consisted of 73 people with memory impairment (IM group). The control group (n = 72) was made of individuals with preserved memory and sociodemographic characteristics similar to the case group (PM group). Both groups improved their performance on everyday memory tasks (measured using the RBMT). The IM group improved more than the PM group in everyday memory tasks, especially in prospective memory tasks. Both groups also reduced their level of subjective complaints as a result of training. In conclusion, our results are encouraging with respect to the efficacy of comprehensive memory training programs for older people with severe memory impairment.  相似文献

Teachers’ homework follow‐up practices, the in‐class strategies teachers use to monitor their students’ homework assignments, have an impact on their students’ homework behaviors and academic achievement. The current study explored the perspectives of middle school mathematics teachers on the three domains of homework follow‐up: the practices used in class, the purposes of each practice, and the aspects that may influence this process. Data were collected from two data sources (i.e., focus groups and classroom observations) and were analyzed using thematic analysis. The findings showed that teachers monitored homework either using a single strategy or a combination of strategies (e.g., checking homework completion and providing individual feedback) linked to a specific purpose (e.g., promote students’ involvement). The teachers also reported that they were under certain constraints when they delivered homework follow‐up practices (e.g., pressure to follow the curriculum), so their practices’ effectiveness sometimes can be compromised. Implications for practice are discussed.  相似文献

Abstract

Social determinants of health are the key to understanding and addressing persistent disparities in adolescent pregnancy in the United States. However, there is little guidance on what concrete steps organizations can take to work at the intersection of social determinants of health (SDoH) and sexual and reproductive health (SH). Two community-based organizations completed a case study using a structured interview guide to illustrate their transition working at this intersection. The Alexandria Campaign on Adolescent Pregnancy and Identity, Inc. arrived at the intersection of SDoH and SH from opposite ends of the road. Despite clear differences in their trajectory, their experiences share four key elements that marked their success in expanding their core work: (a) both organizations enjoyed ample community and political support, (b) they used data to drive strategic decisions, (c) they used funding opportunities to move toward the intersection of sexual health and social determinants, and (d) they leveraged existing programs to sustain their efforts. Organizations working at the intersection must continuously leverage community, political, and financial capital to pursue partners, expand services, and change policies that sustain a holistic approach to youth health and well-being.  相似文献

A word-spotting task is used in Spanish to test the way in which polysyllabic letter-strings are parsed in this language. Monosyllabic words (e.g., bar) embedded at the beginning of a pseudoword were immediately followed by either a coda-forming consonant (e.g., barto) or a vowel (e.g., baros). In the former case, the embedded word corresponds to the first spoken syllable, whereas it cuts across the syllable boundary in the latter case. Unlike a previous study in English using the same methodology (Taft & Álvarez, 2014), the embedded word was found to be easier to detect when followed by a consonant than a vowel, at least for low-frequency words. It was concluded that phonological recoding is more important in the parsing of Spanish words than English words, where maximization of the coda dominates instead.  相似文献

This metalogue addresses the ways Sreyashi Jhumki Basu mediated our practices in science education and life. We focus on Basu’s uses of critical science agency, democratic science classrooms, and critical feminist ethnography to transform the possibilities for all participants in her research and educational practices. We also examine her use of cases and pedagogical strategies to support youth set practice goals based on conceptions of self and preferred learning trajectories. These strategies allow youth to develop power through the use of disciplinary knowledge and modes of inquiry to support their understanding of themselves as powerful, able to change their position in the world, and make the world more socially just. This (Key Contributors) article acknowledges a life cut short through disease, reflects our personal loss of a friend and colleague, and expresses determination to ensure that her contributions to science education are sustained and continued.

Dr. Ahnell examines several tenets of perceptual psychology and makes specific suggestions for their application by supervising teachers. All supervising teachers could benefit from reading this article.  相似文献
