Teaching Them to Teach: Programmatic Evaluation of Graduate Assistants’ Teaching Performance     

Karen Sobel  Susan Avery  Ignacio J. Ferrer-Vinent 《Public Services Quarterly》2016,12(3):189-213

Academic libraries are one of the most important sources of “on the job” training for future library instructors. Librarians who supervise and assess these future library instructors (often in graduate assistant positions) often choose to provide observations and feedback each semester to these instructors in training. Scholarly literature, however, provides little information on whether this system helps graduate assistants to develop as teachers. The authors of this article assessed graduate assistants’ performance as teachers over three semesters using a system of observation and self-assessment. They analyzed both patterns and areas of growth and discuss the strengths and weaknesses of this system.  相似文献

Mapping the knowledge structure exhibited by a cohort of students based on their understanding of how a galvanic cell produces energy          下载免费PDF全文

Adrian Sin Loy Loh  R. Subramaniam 《科学教学研究杂志》2018,55(6):777-809

This study evaluates the use of an open‐ended question to determine students' knowledge structure on the topic of galvanic cells. The open‐ended question was developed and administered to 163 Grade 10 students who had earlier completed a course on electrochemistry. Students' responses were marked as well as coded on the basis of the fields identified from their responses. This was then evaluated statistically to determine the collective knowledge structure of the sample of students. The knowledge structure thus mapped contains both canonical concepts and alternative conceptions (ACs). An important finding emerging from this study is that instructors need to focus student's attention on the dynamic processes involving electrons and ions during the operation of galvanic cells. In order for students to fully understand how a galvanic cell operates, they need to see the whole picture. There are three critical components that lead to students' understanding of how an oxidation–reduction reaction can generate energy and how a circuit is complete: transfer of electrons during oxidation–reduction half‐reactions, flow of electrons within metals, and migration of ions in solution. Also, we found that it is possible for students to use correct chemistry concepts in an incorrect way by establishing linkages among these in an inappropriate manner. We reiterate that apart from evaluating students' ACs, it is also important to evaluate the links between the concepts and conceptions present in students' knowledge structure so that teaching can be made more effective.  相似文献   

Evaluation and publication delay in Ibero-American scientific journals     

Jon Zabala  Borja González-Albo  Ana García-García  Aurora Garrido-Domínguez  José Ignacio Vidal-Liy  Luis R. Álvarez-Díez  Soledad Hernando-Tundidor  Yara Mostazo-Fernández  Teresa Abejón 《Learned Publishing》2023,36(2):205-216

This article analyses the review, acceptance and publication dates of a sample of 21,890 articles from 326 Ibero-American scientific journals from all subject areas and countries included in the Latindex Catalogue 2.0 and published between 2018 and 2020 (freely available as an open access dataset). The aim is to discover evaluation and publication times. The evaluation process takes a median of 110 days, the publication process, a median of 82 days, and the whole process, a median of 224 days. Statistical differences are found according to periodicity, subject areas, countries, existence of a printed version and article type (Call for Papers or General articles). From the data we find that the delay in publication is longer than publishers themselves report to the DOAJ. STEM areas present the most similarity in publication patterns, having a higher number of evaluation days (Ed) than publication days (Pd); Arts and Humanities present the opposite pattern, with a higher Pd than Ed. In the case of Social Sciences, the times are similar. General articles and Call for Papers articles differ in terms of Ed, but not Pd, indicating that Call for Papers revisions are faster.  相似文献

CyberBabel?     

David Loy 《Ethics and Information Technology》2007,9(4):251-258

The new information technologies hold out the promise of instantaneous, 24/7 connection and co-presence. But to be everywhere at once is to be effectively nowhere; to be connected to everyone and everything is to be effectively disconnected. Why then do we long for faster connections and fuller connectivity? The answer this paper proposes is that we are trying to fill our existential lack, our radical sense of inadequacy and incompleteness as human beings. From such a perspective, our pursuit of speed and connectivity is doomed to failure insofar as it only exacerbates the condition we are fleeing. Rather than rushing faster, the Buddhist-inspired solution would have us slow down and directly investigate our sense of lack.  相似文献

This paper provides a new and systematic characterization of 488 universities, from 11 European countries: Finland, France, Germany, Hungary, Italy, Netherlands, Norway, Portugal, Spain, Switzerland and UK. Using micro indicators built on the integrated Aquameth database, we characterize the European university landscape according to the following dimensions: history/foundation of university, dynamics of growth, specialization pattern, subject mix, funding composition, offer profile and productivity.  相似文献

Surface tension effects on submerged electrosprays     

álvaro G. Marín  Ignacio G. Loscertales  Antonio Barrero 《Biomicrofluidics》2012,6(4)

Electrosprays are a powerful technique to generate charged micro/nanodroplets. In the last century, the technique has been extensively studied, developed, and recognized with a shared Nobel price in Chemistry in 2002 for its wide spread application in mass spectrometry. However, nowadays techniques based on microfluidic devices are competing to be the next generation in atomization techniques. Therefore, an interesting development would be to integrate the electrospray technique into a microfluidic liquid-liquid device. Several works in the literature have attempted to build a microfluidic electrospray with disputable results. The main problem for its integration is the lack of knowledge of the working parameters of the liquid-liquid electrospray. The “submerged electrosprays” share similar properties as their counterparts in air. However, in the microfluidic generation of micro/nanodroplets, the liquid-liquid interfaces are normally stabilized with surface active agents, which might have critical effects on the electrospray behavior. In this work, we review the main properties of the submerged electrosprays in liquid baths with no surfactant, and we methodically study the behavior of the system for increasing surfactant concentrations. The different regimes found are then analyzed and compared with both classical and more recent experimental, theoretical and numerical studies. A very rich phenomenology is found when the surface tension is allowed to vary in the system. More concretely, the lower states of electrification achieved with the reduced surface tension regimes might be of interest in biological or biomedical applications in which excessive electrification can be hazardous for the encapsulated entities.  相似文献
