In a large introductory physics course, structured weekly journals (weekly reports) regularly encouraged students to ask questions about the material. The resulting questions were collected for one quarter and coded based on difficulty and topic. Students also took several conceptual tests during the quarter. The reports contained more questions than typically observed in a college classroom, but the number of questions asked was not correlated to any measure of conceptual performance. Relationships among different types of questions and performance on these tests were explored. Deeper‐level questions that focus on concepts, coherence of knowledge, and limitations were related to the variance in student conceptual achievement. © 2003 Wiley Periodicals, Inc.

Based on a qualitative study conducted in austerity-stricken Greece, the paper provides a micro-level exploration of the mechanics of intergenerational transmission of (dis)advantage. Utilising the Bourdieusian toolbox, the paper enquires into familial practices through the lens of young people’s perceptions, focusing on the mobilisation of capitals, the inculcation and transformation of habitus taking place in the Greek educational field. In-depth interview material unpacks the pedagogic efforts young people and their families make, indicating that these are contingent on the varied volume and composition of capitals and the distinct distances from necessity that in turn constrain or afford the exercise of agency and the investments in the academic market. Further, the analysis sheds light on young people’s accounts of educational and occupational expectations illustrating how these are tightly interweaved with familial legacies and parental wishes, and underpinned by the projects of distinction, mobility and respectability through education. 相似文献

Found in all eukaryotic cells, linker histones H1 are known to bind to and rearrange nucleosomal linker DNA. In vitro, the fundamental nature of H1∕DNA interactions has attracted wide interest among research communities-from biologists to physicists. Hence, H1∕DNA binding processes and structural and dynamical information about these self-assemblies are of broad importance. Targeting a quantitative understanding of H1 induced DNA compaction mechanisms, our strategy is based on using small-angle x-ray microdiffraction in combination with microfluidics. The usage of microfluidic hydrodynamic focusing devices facilitates a microscale control of these self-assembly processes, which cannot be achieved using conventional bulk setups. In addition, the method enables time-resolved access to structure formation in situ, in particular, to transient intermediate states. The observed time dependent structure evolution shows that the H1∕DNA interaction can be described as a two-step process: an initial unspecific binding of H1 to DNA is followed by a rearrangement of molecules within the formed assemblies. The second step is most likely induced by interactions between the DNA and the H1's charged side chains. This leads to an increase in lattice spacing within the DNA∕protein assembly and induces a decrease in the correlation length of the mesophases, probably due to a local bending of the DNA. 相似文献

This presentation reviewed the standard model licenses that are available, including models such as LicensingModels.org and LibLicense, plus institution-specific licenses available online. The licenses’ strengths and weaknesses as templates were discussed. Best practices for creating a license template at one’s own institution were modeled, with standard language that one can use in negotiation. Problems and gaps in model licenses were raised, including formats or kinds of purchases that require new language that has not yet been standardized (such as e-books and streaming media). Suggestions for developing a new model license through community action were discussed. 相似文献

At school, pupils often cooperate on common projects and must coordinate their different individual actions. However, grades are pervasively used even in cooperative situations, which make the pupils’ differences in achievement and their relative rank salient and may reduce their inclination to work constructively with others. Thus, we hypothesized that grades would elicit disruptive interactions and reduce performance in a cooperative cognitive-motor task necessitating inter-individual coordination of members. In a study with 5th graders, grades (vs. a neutral concept) were primed at the onset of a cooperative group interaction. Results showed that, although pupils were set to work cooperatively, priming grades (vs. neutral concepts) harmed inter-individual coordination by eliciting more negative dominant behaviours among pupils during interactions, which decreased group performance. 相似文献

The educator's point of view stresses the development potential of education, together with respect for human rights. It is seen that nations need to make clear policy statements in this respect, and the consequent planning and curricular issues, together with some relevant strategies, are indicated.
Zusammenfassung Im Standpunkt des Pädagogen wird gemeinsam mit der Anerkennung der Menschenrechte das Entwicklungspotential der Bildung betont. Nach Meinung des Autors müssen Nationen in diesem Zusammenhang klare politische Aussagen treffen, und der Artikel befaßt sich mit der entsprechenden Planung sowie Themen zum Curriculum und einigen relevanten Strategien.
Résumé Le point de vue de l'éducateur souligne le potentiel de développement offert par l'éducation, ainsi que le respect des droits humains. Il s'avère que chaque nation doit énoncer clairement sa politique à cet égard; l'auteur indique les questions de planification et de curriculum qui en découlent, ainsi que quelques stratégies pertinentes.相似文献

We conducted a meta-analysis to investigate the effectiveness of interventions aimed at reducing teacher burnout. Online and reference list searches yielded 513 unique results, and the final sample contains 23 controlled trials (19 journal articles and 4 unpublished dissertations). More than two thirds of the studies had optimal quality, and the risk of bias was not related to the overall effectiveness of the interventions. The overall effects were small, but statistically significant (d = 0.18, SE = 0.05, Z = 3.26, p < 0.001, k = 23). Separate analyses on each burnout component showed similar intervention effects on emotional exhaustion and personal accomplishment, but almost null effects on depersonalization (d = 0.03, SE = 0.06, Z = 0.53, p > 0.05, k = 11). Additional moderator analyses suggested that mindfulness interventions had significant effects on exhaustion and personal accomplishment. Interventions on primary and middle school teachers reported effect sizes below the average effect. Similar to previous findings, interventions that lasted less than 1 month had the smallest levels of efficacy. 相似文献
