Aportes para la construcción de un modelo conceptual para el diseño, evaluación e investigación en educación virtual

El artículo se centra en el estado incipiente del soporte teórico de la educación dada en entornos digitales. Con fines de contribuir con el desarrollo de dicho soporte, ofrece un modelo conceptual fundamentado en un enfoque constructivista sociocultural, como referente para el diseño, la evaluación y la investigación en el campo particular de la educación digital. El modelo es resultado de la ampliación justificada del triángulo interactivo propuesto por Coll (1996; 2004) para el análisis de las actividades educativas. Está constituido por cuatro grupos de factores: del contenido, del estudiante, del docente y de las condiciones técnico-ambientales del programa, permitiendo abordar sistemáticamente las particularidades de las actividades educativas dadas en entornos digitales. Sustentado en fuentes actualizadas, el artículo presenta y describe los factores más relevantes de cada grupo.

Work instability. Presentation of an empirical model about its psychological impact

Research on the impact that work instability has on workers has the limitation of assess the relations among different variables separately, without examining the possible mediation relationships that can exists between them. The aim of this article is to test a conceptual model of the mediating relations between the uneasiness due to work instability and the psychological impact, in the framework of interactive stress theory, conducting a Path Analysis. 191 workers participated on the study, with a mean age of 31 years-old (SD = 11). Results showed that the proposed model didn't fit to the data. Alternative models were explored, consistent with the original conceptual model and the empiric evidence. A new causal model is proposed, where Uneasiness due to Work Instability as an independent variable, Personal Strain and Personal Resources as intervenient variables, and Anger, Hopelessness, and Satisfaction as dependent ones. The theoretical and empirical importance of the resulting model is discussed.

Information Management and Mediation in a Digital Reference Service Focused in Social Sciences

This paper investigates the current relationship between information management and information mediation along with the digital reference service through a case study which took place in an academic library. The concept of information mediation is herein analyzed, since a conceptual examination provides elements that will help people to comprehend and evaluate the concerned service. The information professional plays a very important role in the mediation aforementioned, which may be directly or indirectly; consciously or unconsciously; by himself/herself or plurally; individually or inserted into a group ? in all such manners that mediator facilitates the acquisition of information, fully or partially satisfying a user?s need of all sorts of knowledge. Meanwhile, we here approach information management from a scope that points out a description over performed activities concerned to policies and procedures put into effect until the service evaluation by proposing a criterion for such point. Finally, we outline a few actions to be implemented in long-term perspective, which goal is to continually ameliorate such assistance, taking in account the human factor
