The rise of digital media labs and spaces for content creation in public libraries has been documented in the scholarly literature. However, fewer studies have investigated the outcomes of media literacy initiatives in community media centers (CMCs) and how they might inform similar programs and services in public libraries. This article reports findings from a study that used qualitative research to investigate the current goals and activities of CMCs across the United States. The findings show that the educational, social, and community benefits of these programs could be useful for public libraries to consider in developing or augmenting their own media literacy initiatives.  相似文献

ABSTRACT

This study used citation analysis in conjunction with a subjective rubric with five validated criteria to assess the quality of a purposive sample of 452 education dissertation reference lists produced at a nontraditional institution from six doctoral programs. These programs used a variety of distance education models. The citations were then compared with the 100 reference lists selected from doctoral education programs at 10 traditional institutions. Criteria included the breadth of resources, depth of the literature review as shown through the citing of critical historical and theoretical works, depth as demonstrated through the scholarliness of citations chosen, currency, and relevancy. The study discusses how the expanded sample of traditional reference lists continued to demonstrate consistent patterns. In contrast, although the sample of reference lists from distance education programs was much expanded, the patterns of the subsets of reference lists at the nontraditional institution were significantly diverse. The patterns of 35 doctoral reference lists from another for-profit, nontraditional institution known for providing distance education were also examined to compare the results of the two nontraditional programs. Possible reasons for differences in citation patterns by traditional and nontraditional programs are discussed, and the possible role of distance education and program criteria are examined for insights they offer into the use of citation analysis as an assessment tool of the library research skills of doctoral students.  相似文献

Educational researchers and teachers are well aware that misconceptions—erroneous ideas that differ from the scientifically accepted ones—are very common amongst students. Daily experiences, creative and perceptive thinking and science textbooks give rise to students' misconceptions which lead them to draw erroneous conclusions that become strongly attached to their views and somehow affect subsequent learning. The main scope of this study was to understand what students consider a mineral to be and why. Therefore, the goals were (1) to identify eleventh-grade students' misconceptions about the mineral concept; (2) to understand which variables (gender, parents' education level and attitude towards science) influenced students' conceptions; and (3) to create teaching tools for the prevention of misconceptions. In order to achieve these goals, a diagnostic instrument (DI), constituted of a two-tier diagnostic test and a Science Attitude Questionnaire, was developed to be used with a sample of 89 twelfth-grade students from five schools located in central Portugal. As far as we know, this is the first DI developed for the analysis of misconceptions about the mineral concept. Data analysis allows us to conclude that students had serious difficulties in understanding the mineral concept, having easily formed misconceptions. The variables gender and parents' education level influence certain students' conceptions. This study provides a valuable basis for reflection on teaching and learning strategies, especially on this particular theme.  相似文献

Abstract

Rapid development of informatics makes possible the application of multimedia and world informatics systems in our educational work. We are concentrating strongly on this theme at our university utilizing the support of different funds (Phare, TEMPUS, World Bank). We have established an education centre that opens new perspectives in medical education by using both modern and traditional media. Recently, we have engaged in a new instructional system in which the educational units connecting to the education centre can make the old dream of ‘problem‐based learning’ come true.  相似文献

Variables subject to an order restriction, for instance Y  X, have a bivariate distribution over a non-rectangular joint domain that entails a non-null and potentially large structural relation even if the variables show no association (in the sense that particular ranges of values of X do not co-occur with particular ranges of values of Y). Order restrictions affect a number of scientometric indices (including the h index and its variants) that are routinely subjected to correlational analyses to assess whether they provide redundant information, but these correlations are contaminated by the structural relation. This paper proposes an alternative definition of association between variables subject to an order restriction that eliminates their structural relation and reverts to the conventional definition when applied to variables that are not subject to order restrictions. This alternative definition is illustrated in a number of theoretical cases and it is also applied to empirical data involving scientometric indices subject to an order restriction. A test statistic is also derived which allows testing for the significance of an association between variables subject to an order restriction.  相似文献

This article investigates mental representations of literary characters and their relations with other aspects of response to literature and age, gender, and expertise. A Saga chapter and the beginning of a contemporary novel were presented to 16 participants from each of three age groups (13 years, 17 years, adults) equally divided by gender and expertise level. After having evaluated the texts with rating scales, participants were interviewed on the main character of each text. The similarity between participants’ answers was computed and used for a cluster analysis. Four clusters (representation types) were identified for one character and five for the other. Character representation was affected by age but not by expertise and gender, and was unrelated to other aspects of response to literary text. Explicit ratings of the texts, instead, were affected by expertise. Theoretical and educational implications are discussed.  相似文献

This article summarizes recent efforts by Latin-American theologians concerned with developing a pluralist theology of liberation. The author highlights some of the most significant issues and themes of this emerging theological reflection among liberation theologians. Finally, he identifies some of the challenges a pluralist theology of liberation raises for our task as religious educators in North America.  相似文献

Resumen

La presente investigación analiza la relación entre la adquisición de la clasificación y la ca- pacidad para realizar inferencias causales. Además, se pretende comprobar en qué medida los contenidos de las historias causales (en términos de animado/inanimado, de los antecedentes y los consecuentes) provocan diferencias en la ejecución. Participaron 70 niños de 8 centros públicos de EGB de Murcia, el rango de edad oscilaba entre 4;0 y 7;10. Los resultados indican cómo a medida que los sujetos dominan la clasificación muestran una mayor capacidad para realizar inferencias causales. No aparecen diferencias en la ejecución debida a los contenidos de las historias. Finalmente, se propone un modelo causal, a partir del modelo de equilibrio de la teoría de Piaget, sobre el desarrollo de las inferencias causales.  相似文献

Resumen

En este trabajo se aborda el estudio de los procedimientos y estrategias desarrollados por los niños para solucionar situaciones problemáticas relacionadas con la multiplicación aritmética. El análisis de dichos procedimientos nos muestra cómo dicha noción comporta un nivel de mayor complejidad que la adición, lo que es necesario tener en cuenta en el momento de enseñarla.  相似文献
