El papel del análisis gráfico en la resolución de problemas aritméticos

El planteamiento de los problemas matemáticos adopta tradicionalmente una formulación verbal. Pero dar cuenta con la palabra de los elementos y las relaciones que caracterizan la situación de un problema tiene sus ventajas y sus limitaciones y a veces el niño no alcanza a representarse correctamente los hechos: no alcanza a encontrar los referentes concretos que soportan esas expresiones verbales con cierto grado de abstracción. Se ha sugerido que la ayuda de representación y esquemas gráficos facilita una mejor comprensión del problema que la formulación verbal. En este articulo se presenta una investigación que lo demuestra.     

Modeling teacher empowerment: The role of job satisfaction

Empowerment is defined and measured in terms of teachers' power to participate in decision-making about teaching and learning conditions. Job satisfaction refers to the level of teacher satisfaction by matters related to these conditions: student achievement, decision-making ability, self-growth, and so on. This research considers the relationship between job satisfaction and teacher empowerment, which includes dimensions of job satisfaction that contribute to teacher empowerment. In particular, it examines the levels of teacher satisfaction in four dimensions (professional growth, decision-making, promotion, and status) and their contribution to the sense of teacher empowerment among Cypriot teachers. The results support the importance of job satisfaction in the construction of teacher empowerment. Specifically, (1) teachers' level of job satisfaction varies depending on the dimension of school life that is focused; (2) teachers' job satisfaction is related to teacher empowerment.     

Intellectual giftedness: Economic,political, cultural,and psychological considerations

The concept of intellectual giftedness has had a long history in the literature of psychology and education. However, though the existence of the phenomenon underlying this concept has never actually been disputed, there are multiple ongoing debates regarding its definition, methods for its identification, and subsequent programming. This essay is conceived to contribute to the discussion on intellectual giftedness and to provide a global context for the other articles in this issue. The essay is comprised of three major parts. First, we review the defining terms, contexts and theories historically and currently applied to the understanding of intellectual giftedness. Second, we comment on models used to identify it. Third, we discuss the major influences that directly shape the treatment of giftedness in a number of international settings.     

Measuring the impact of inquiry-based learning on outcomes and student satisfaction

The aim of this study is to determine the impact of inquiry-based learning (IBL) on students’ academic performance and to assess their satisfaction with the process. Linear and logistic regression analyses show that examination grades are positively related to attendance at classes and tutorials; moreover, there is a positive significant relationship between academic performance and IBL, which is considered useful for better understanding of the subject. While students’ satisfaction is directly associated with class attendance and motivation and with the perceived usefulness of IBL, it is unaffected by attendance at tutorials. We conclude, therefore, that students become more involved in learning and acquire increased knowledge of the subject when an IBL-based method is followed.     

Reasons and mediators in the development and communication of personal digital stories

The expansion of access to devices, as well as the production and publication options in social networks requires a broader definition of the traditional notion of personal digital storytelling. To get a deeper understanding of these practices in the group of adolescents, the objective of this article is to analyze what are the reasons that direct the publications of personal stories and what kind of filters, agents and consequences are articulated in these stories. To do this, the most qualitative part of an investigation on teenagers’ internet publication guidelines is synthesized. Specifically, the results of a semi-structured interview with 12 adolescents between 12 and 20 years are shown. The answers show that the interviewees’ perspective on what a digital story is goes beyond the format and varies depending on the network where it is published and the type of content. Thus, the emphasis and motivation of the publication has shifted from the digital - which has been incorporated with something normal and not differential - towards the personal, focusing the publications on the daily life of young people. An extension and refinement of the public-private dichotomy has been identified, maintaining general privacy guidelines above the dissemination of publications. As for filters, publications are preceded by the widespread use of image modification tools. Finally, the answers show the influence of personal agents, mostly friends and brothers, and technology agents, which determine the relationship between the type of story and the network where it is published.

     

Quality in virtual education environments

The emergence of the Internet has changed the way we teach and learn. This paper provides a general overview of the state of the quality of virtual education environments. First of all, some problems with the quality criteria applied in this field and the need to develop quality seals are presented. Likewise, the dimensions and subdimensions of an empirical instrument to improve and assess the quality of online education are examined. This tool has already been applied to several educational contexts; though not definitive, it aims to improve not only specific areas, but also the whole educational approach as a system.
