Actividad conjunta y habla: una aproximación al estudio de los mecanismos de influencia educativa

Resumen

El artículo presenta las principales opciones teóricas y metodológicas de un proyecto de investigación cuyo objetivo principal es el estudio de algunos mecanismos de influencia educativa que se manifiestan en, o actúan a través de, la interacción profesor/grupo de alumnos y adulterino. Utilizando como punto de partida el concepto de interactividad, término acuñado para designar las formas de organización de la actividad conjunta en torno al contenido o tarea que están llevando a cabo los participantes, se analizan dos mecanismos de influencia educativa: la cesión y el traspaso progresivos del control y la responsabilidad y la construcción progresiva de sistemas de significados compartidos.     

Private versus public financing of higher education: U.S. policy in comparative perspective

Funding policies for higher education differ greatly from nation to nation and one of the major debates concerns the private-public mix. Five principal patterns emerge from the following variables: whether the system is comprised of just one sector or dual private-public sectors, the size of each sector (if there are dual sectors), the contribution of private funds to each sector, and the contribution of public funds to each sector. Beyond their defining empirical characteristics, each pattern is based on distinctive historical and normative rationales. Each therefore faces different policy choices within the more general private-public debate, although certain basic value questions commonly arise. Seen in comparative perspective, the United States continues to stand out for its significant dependence on private finance. This is because, compared to other developed nations, the United States still has an exceptionally large private sector with relatively great private finance and because, compared to almost all countries, the U.S. public sector also attracts substantial private income. There is great variation, however, and individual U.S. state systems may find useful counterparts to their empirical realities and policy dilemmas in certain foreign (national) systems.     

Fearfulness in female and male cats

Cats were observed in four moderately frightening novel situations. One of 12 response measures indicated that females are more fearful than males, 1 indicated that males are more fearful than females, and the remaining 10 measures revealed no significant difference between males and females. The results thus yield no evidence of any large and consistent difference in fear between female and male cats. Gonadal hormones do not determine any single pattern of sex difference in fearfulness in different species of mammals. Species-specific patterns of social organization may predict sex differences in fear in studied species more accurately than endocrine factors.     

El lenguaje de los niños de 3 a 10 años desde la perspectiva funcional

¿Para qué utiliza el lenguaje el niño? ¿Existen funciones del lenguaje más o menos fuertes o más o menos presentes a lo largo de su desarrollo? En el trabajo, que presenta datos empíricos sobre el peso de las distintas funciones del lenguaje desde los 3 a los 10 años, pueden apreciarse cambios evolutivos importantes respecto al protagonismo de estas funciones.     

The contribution of reflective learning to experiential learning in business education

Abstract

Experiential learning theory states that reflection is just as important to learning as action. However, business educators often overlook reflection in their experiential learning activities, especially when it’s understood as a dialogue process. Drawing on reflective learning theory, we explored the case of an undergraduate business programme that has been combining experiential learning with three different reflective learning mechanisms for the past ten years. Results show that: (1) reflective dialogue is central for ensuring that impressions from experience translate into better-defined learning outcomes, (2) this dialogue process greatly benefits from a closely guided process, and (3) different reflection mechanisms contribute differently to the learning process. Considering how fast experiential learning has popularised in business schools, this study alerts educators to the importance of combining their experiential learning activities with a guided process of reflection. Otherwise, educators risk students extracting meagre, wrong or misleading impressions from their experience.     

The influence of core teaching conceptions on teachers' use of inquiry teaching practices

This article investigates three teachers' conceptions and use of inquiry‐based instructional strategies throughout a professional development program. The professional development program consisted of a 2‐week summer inquiry institute and research experience in university scientists' laboratories, as well as three academic year workshops. Insights gained from an in‐depth study of these three secondary teachers resulted in a model of teacher conceptions that can be used to direct future inquiry professional development. Teachers' conceptions of inquiry teaching were established through intensive case–study research that incorporated extensive classroom observations and interviews. Through their participation in the professional development experience, the teachers gained a deeper understanding of how to implement inquiry practices in their classrooms. The teachers gained confidence and practice with inquiry methods through developing and presenting their institute‐developed inquiry lessons, through observing other teachers' lessons, and participating as students in the workshop inquiry activities. Data analysis revealed that a set of four core conceptions guided the teachers' use of inquiry‐based practices in their classrooms. The teachers' conceptions of science, their students, effective teaching practices, and the purpose of education influenced the type and amount of inquiry instruction performed in the high school classrooms. The research findings suggest that to be successful inquiry professional development must not only teach inquiry knowledge, but it must also assess and address teachers' core teaching conceptions. © 2007 Wiley Periodicals, Inc.

Data-driven assessment of teacher candidates during their internships in deaf education

Deaf education teacher training programs have received criticism for graduating students with gaps in knowledge and skills required for specific placements. The National Council for Accreditation of Teacher Education (NCATE) requires that accredited programs engage in self-study, and NCATE guidelines require programs to collect valid, reliable evidence of teacher candidate performance and candidates' effect on student learning. In the present study, an ecobehavioral assessment computer program, MS-CISSAR (Mainstream Code for Instructional Structure and Student Academic Response), was used in evaluations of 8 teacher candidates during internship experiences. Results were mixed. Some of the instructional arrangements, teaching behaviors, and student responses resembled those found in studies using in-service teachers as subjects; however, some data revealed a need for changes in instruction. Data gathered with MS-CISSAR could be added to evaluations to help training programs meet NCATE requirements for evidence on teacher candidate performance and candidates' effect on student learning.     

The Use of Online Modules and the Effect on Student Outcomes in a High School Chemistry Class

The purpose of the study was to review the efficacy of online chemistry simulations in a high school chemistry class and provide discussion of the factors that may affect student learning. The sample consisted of 351 high school students exposed to online simulations. Researchers administered a pretest, intermediate test and posttest to measure chemistry content knowledge acquired during the use of online chemistry laboratory simulations. The authors also analyzed student journal entries as an attitudinal measure of chemistry during the simulation experience. The four analyses conducted were Repeated Time Measures Analysis of Variance, a three-way Analysis of Variance, Logistic Regression and Multiple Analysis of Variance. Each of these analyses provides for a slightly different aspect of factors regarding student attitudes and outcomes. Results indicate that there is a statistically significant main effect across grouping type (experimental versus control, p = 0.042, α = 0.05). Analysis of student journal entries suggests that attitudinal factors may affect student outcomes concerning the use of online supplemental instruction. Implications for this study show that the use of online simulations promotes increased understanding of chemistry content through open-ended and interactive questioning.
