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

E-readers provide an opportunity for hospital librarians to reach out to staff and patients with new approaches to library lending. Librarians in four Veterans Health Administration medical centers are using e-readers to enlarge their scope of service in unique ways. The libraries of VA hospitals in Minneapolis, Des Moines, Tampa, and Philadelphia have developed several ways to reach out to new library users. 相似文献

There has been a good deal of informal, anecdotal discussion about undergraduate computer science enrollment trends at liberal arts colleges. While this information can be helpful, it is difficult to do detailed planning on the basis of informal and unsubstantiated evidence. This article presents quantitative data about enrollments in the computer science program at Macalester College for the eight‐year period 1985‐1992. The article also compares our local data with information on computer science enrollments from 11 national liberal arts colleges. These data incorporate enrollments at all levels of the curriculum‐‐service, introductory, core, and advanced courses. They also include information on the number of majors and graduates. Based on the data, we draw a set of 10 “observations” about enrollments trends which can help computer science departments in their long‐term planning and budgeting process. 相似文献

The concept of energy is one key component of science education curricula worldwide. While it is still being taught in many science classrooms from a mainly conceptual knowledge perspective, the need to frame the concept of energy as a socioscientific issue and implement it in the context of citizenship education and education for sustainable development, is getting more and more explicit. As we will be faced with limited fossil fuels and the consequences of global climate change in the future, students have to be supported in becoming literate citizens who are able to reach informed energy-related decisions. In this article, we focus on students’ reasoning and decision-making processes about socioscientific energy-related issues. In more detail, we developed a paper-and-pencil measurement instrument to assess secondary school students’ competencies in this domain. The functioning of the measurement instrument was analysed with a sample of 850 students from grades 6, 8, 10 and 12 using item response theory. Findings show that the measurement instrument functions in terms of reliability and validity. Concerning student ability, elaborate reasoning and decision-making was characterised by the use of trade-offs and the ability to weigh arguments and to reflect on the structure of reasoning and decision-making processes. The developed measurement instrument provides a complement for existing test instruments on conceptual knowledge about the concept of energy. It aims to contribute to a change in teaching about energy, especially in physics education in the sense of education for sustainable development. 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

Abstract Educators have invested considerable effort in developing environmental education programs that address students' knowledge, attitudes, and action competence regarding environmental issues. The authors explore the effectiveness of such programs in terms of both student learning outcomes and the intergenerational influence that results when students discuss their learning experiences with their parents and other community members. Six environmental education programs involving 284 students in Queensland schools, from Grades 5-12, were investigated. Students and their parents were surveyed and interviewed regarding their perceptions about the program, the program's influence on their environmental learning, and the extent and nature of discussions that the program stimulated between students and their parents. The authors draw conclusions about key features that should be incorporated into environmental education programs to encourage and empower students to bring about environmental change in their homes and communities. 相似文献

This study draws on the Fragile Families and Child Wellbeing Study (N = 2,032), a birth cohort study of families with children from 20 U.S. cities. Interviews occurred between August 2007, and February 2010, when the children were approximately 9 years old. Macro-economic indicators of the Great Recession such as the Consumer Sentiment Index and unemployment and home foreclosure rates were matched to the data to estimate the links between different measures of the Great Recession and high frequency maternal spanking. We find that the large decline in consumer confidence during the Great Recession, as measured by the Consumer Sentiment Index, was associated with worse parenting behavior. In particular, lower levels of consumer confidence were associated with increased levels of high frequency spanking, a parenting behavior that is associated with greater likelihood of being contacted by child protective services. 相似文献

On August 8, 1974, having been toppled from power by the Watergate scandal, Richard M. Nixon became the first President to resign his office before completing his term. In his resignation speech, Mr. Nixon attempted to vindicate himself before the American people. Analysis of Mr. Nixon's address reveals that his strategies of denial of intent and transcendence to a larger context were largely unsuccessful in securing closure with his audience. 相似文献
