American television programs have been criticized for being filled with images endorsing capitalist consumerism and for being weighted toward the upper middle classes. This study proposed that heavy viewing of these distorted representations may culminate in decreases in viewers' life satisfaction. A path model investigated this supposition, based on material value and social comparison perspectives. Surveys were administered to 225 adults in a northeastern town in the United States, and the data were subjected to path analysis. The findings of this study suggest that heavy television viewing may be associated with material value, estimates of other people's affluence, and perceived gaps between the self and others in material affluence. Of importance, the findings also suggest that the perceived gaps between the self and others may be associated both with dissatisfaction with personal life and dissatisfaction with current social equality, whereas material value may be associated only with dissatisfaction with personal life. 相似文献

Since its inception in 2002, COUNTER has given hope to many librarians charged with collecting usage data for their online collections. This hope turned to optimism in 2007 with the release of SUSHI (Standardized Usage Harvesting Initiative) as a NISO standard (Z39.93). In 2009 release 3 of the COUNTER Code of Practice for Journals and Databases takes effect and with it are some significant advances that will turn hopes and optimism into realities. This article describes the changes and their implications. 相似文献

Ever since OpenURL linking was introduced in 2000 by Herbert van de Sompel the link resolver has played an important role in providing users with access to the online resources they have rights to. From the start, one of the criticisms of OpenURL linking has been that it is not 100% successful—sometimes the user is presented with a link to full text, but that link fails. In 2010 a new National Information Standards Organization (NISO) workgroup was created to tackle the issue of OpenURL quality. This column will discuss this NISO initiative and look in detail at the proposed “Completeness Index” that promises a means of measuring the quality of OpenURLs being submitted by various content providers. The article will also discuss how some OpenURL quality issues may be more perception than reality and how librarians can configure their links and link resolvers to overcome these negative perceptions. 相似文献

ONIX for Publication License (ONIX-PL) was introduced in 2006 with great hope that it would simplify the licensing and license management aspects of e-resource management. However, after several years this standard has not seen significant commercial adoption. Believing this standard still holds promise, the National Information Standards Organization, with funding from the Andrew W. Mellon Foundation and support from Jisc and EDItEUR, has launched the ONIX-PL License Encoding Project. The goal of the project is to accelerate adoption by creating and making publicly available a set of publisher licenses encoded to the ONIX-PL standard. In this column we provide more details on the project, its goals, challenges, and prospects. 相似文献

The Counting Online Usage of Networked Electronic Resources (COUNTER) Code of Practice and Standardized Usage Statistics Harvesting Initiative (SUSHI) are two standards whose successful adoption will greatly assist librarians in performing accurate and timely usage analysis of their online collections and thus make more informed collection management decisions. Variations in how these standards have been applied by content providers to their SUSHI and COUNTER implementation are currently impacting their widespread adoption. The standards themselves are not broken—what is needed is concise guidelines on their implementation. This column reviews some of the roadblocks that impede consistent implementation of these standards as well as proposes recommendations that could form the basis of a community profile for these standards. 相似文献

Interest in inquiry-based science education (IBSE) often pays little heed to the complex power relations that exist within classrooms. A common obstacle to inquiry is that it strongly diverges from current classroom culture and hence, is outside the sphere of teachers' and students' experiences. Teachers and students bring expectations to the classroom that are entrenched in traditional practices and influenced by dynamics of power that exist within all teacher–student relationships. This study, which emerged during a wider study of the use of a Virtual Chemistry Lab in supporting IBSE, explores how classroom discourse constructs and maintains power relations that either stifle or facilitate inquiry-based approaches in two science lessons. Research methods included teacher interviews, student focus groups, video-recorded lessons, and student self-assessments. Findings indicate distinctive features of power inside the classroom that impact on inquiry-based instruction, such as predominant teacher monitoring on task completion over task understanding, lack of student engagement in ownership of scientific ideas, and prevailing norms of what effective teacher questioning is. We discuss implications for IBSE change efforts, highlighting that well-established power relations currently represent an important limiting factor in the capacity of teachers' IBSE implementation. 相似文献

This two‐year, mixed methods study with surveys, observations, and interviews, documented student technology use and skill before and after the implementation of a new one‐to‐one tablet computing program at a private middle school in the United States. After one year with tablets, several differences in students' technology use and skill were documented, including: higher satisfaction with school technology, greater frequency of technology use in specific subjects such as math and science, greater frequency of certain classroom activities such as two‐way communicating, and greater technology skills on competencies such as editing collaborative wikis. New modes of student collaboration were evident after implementing the tablet program, including sharing notes and co‐editing wikis. Differences were inconsistent across grade levels and subjects, suggesting teachers are adopting the tablet innovation differentially. In general, technology use increased most in math, science, and social studies classrooms, with smaller increases in language arts and foreign language classrooms. Différences d'usages et de compétences technologiques rapportées par les élèves après la mise en place de programmes informatiques individualisés La présente étude fondée sur un mélange de méthodes a duré deux années avec des enquêtes, des observations et des entretiens; elle a relevé les usages et les compétences des élèves avant et après la mise en place d'un nouveau programme d'informatique individualisée avec des ordinateurs “tablet” dans une école secondaire privée, aux Etats Unis. Après une année d'usage des “tablets”, on a noté chez les élèves plusieurs différences d'utilisation et de savoir‐faire comme par exemple: un niveau de satisfaction plus élevé par rapport à la technologie de l'établissement, une plus grande fréquence dans l'usage de la technologie pour des matières spécifiques telles que les maths et les sciences, une plus grande fréquence dans certaines activités de classe telles que la communication à double sens, et un plus grand savoir‐faire technologique pour des compétences telles que la mise en forme de wikis collaboratifs. De nouveaux modes de collaboration entre élèves sont apparus clairement après la mise en place du programme “tablet” y compris le partage de notes et la co‐édition de wikis. Il n'y avait pas de cohérence dans les différences d'une classe et d'une matière à l'autre ce qui permet de penser que les enseignants adoptent l'innovation des “tablets” de façon différenciée. En général, l'usage de la technologie a le plus augmenté dans les classes de maths, de sciences et de sciences sociales, l'augmentation étant moins forte dans les classes de lettres et de langues étrangères. Von Schülern berichtete Unterschiede in ihrer Technikanwendung nach Einführung von ?One‐to‐One Computing“ Diese zwei‐jährige, mit verschiedenen Methoden arbeitende Untersuchung, mit Umfragen, Beobachtungen und Interviews, dokumentiert den Technologieeinsatz und die Kompetenz von Studenten vor und nach dem Einsatz eines neuen One‐to‐One Tablett‐Computer Programms an einer privaten Mittelschule der Vereinigten Staaten. Nach einem Jahr Nutzung der Tablettrechner wurden einige Unterschiede beim Technologiegebrauch und den Fertigkeiten bei den Studenten festgestellt, einschließlich einem höheren Zufriedenheitsgrad mit der Schultechnologie, öfterer Technologieverwendung in besonderen Fächern wie Mathematik und Naturwissenschaften, höherer Nutzung von Unterrichtsaktivitäten wie wechselseitiger Kommunikation und verbesserten Fertigkeiten und Kompetenzen in der Technologienutzung, z.B. bei der gemeinsamen Bearbeitung von Wikies. Neue Formen der studentischen Zusammenarbeit wurden erkennbar, nachdem das Tablett‐Programm eingerichtet worden war. Einige Differenzen blieben – abhängig von der Anspruchshöhe und den Testpersonen – widersprüchlich, was auch auf die unterschiedliche Nutzung der Programme durch die Lehrer zurückzuführen sein kann. Im Allgemeinen wuchs die Technikverwendung am meisten in Mathematik, den Naturwissenschaften und den soziologisch orientierten Fächern, weniger den Sprach‐ und Fremdsprachenbereichen. Diferencias de uso y competencias en tecnologías relatas por los alumnos después de la introducción de la informática individualizada. Este estudio de dos años y de métodos mixtos con encuestas, observaciones y entrevistas ha apuntado el uso y las destrezas de los alumnos en relación con la tecnología antes y después de la introducción de un nuevo programa “Tablet” de informática individualizada en un colegio secundario privado de los Estados Unidos. Después de un año con los “Tablets”, se notó varias diferencias en los usos y destrezas de los alumnos en relación con la tecnología, incluyendo: más sarisfacción con la tecnología de la escuela, un uso más frecuente de la tecnología en asignaturas como matemáticas y ciencias, una frecuencia más alta de ciertas actividades de aula como la comunicación bilateral y más destrezas tecnológicas en competencias como la edición de wikis colaborativos. Nuevas formas de colaboración estudiantil aparecierón claramente después de la introducción, del programa “Tablet”, entre ellas el reparto de apuntes y la co‐edición de wikis. Las diferencias entre niveles y asignaturas resultaron inconsistentes lo que conduce a pensar que los profesores están adoptando la inovación del “Tablet” de varias maneras. En general el incremento del uso de la tecnología fue más fuerte en las aulas de matemáticas, ciencias y ciencias sociales con incrementos más bajos en aulas de Humanidades y lenguas extranjeras. 相似文献

Previous research indicates that academic emotions are largely organized along domain-specific lines. In the present study (N = 1,687; Grades 8/11), the authors explored the domain specificity of academic emotions in terms of the moderating influence of having the same versus a different course instructor across domains. The authors evaluated discrete emotions consisting of enjoyment, pride, anxiety, anger, and boredom as experienced in the academic domains of mathematics and physics. Consistent with previous findings, between-domain relations for these emotions were relatively weak. These relations were, however, significantly stronger in classes having the same instructor in mathematics and physics compared with classes having different instructors for each subject. Nevertheless, the between-domain relations in classes having the same instructor were not strong enough to disconfirm the domain-specific conceptualization of academic emotions. Last, the authors discuss directions for future research on additional factors potentially affecting the strength of between-domain relations of academic emotions. 相似文献
