Google Scholar's Coverage of the Engineering Literature 10 years Later     

Carmen Cole  Angela R. Davis  Vanessa Eyer  John J. Meier 《The Journal of Academic Librarianship》2018,44(3):419-425

In 2008 Meier and Conkling first tested Google Scholar's coverage of the engineering literature against citations gathered from the Compendex database. Since that time, other studies have used the same methodology and found improvement in Google Scholar's coverage. This study uses engineering dissertations from Proquest Dissertations & Theses to create a data set of citations for the comparison of fee-based databases, Compendex and Scopus, against Google Scholar. From 1950 to 2017 Google Scholar outperformed both Compendex and Scopus in discoverability of citations in nine engineering subjects. These results have implications for collection management and information literacy program planning for librarians.  相似文献

Coeducational and single-sex physical education: students’ situational interest in learning tasks centred on technical skills     

Vanessa Lentillon-Kaestner  Cédric Roure 《Physical Education & Sport Pedagogy》2019,24(3):287-300

Background: A student’s choice to engage in a learning task is highly related to the student’s environmental stimuli and his or her perception of interest. From this perspective, the construct of situational interest (SI) has been used to interpret students’ motivation in task engagement. SI is assumed to be transitory, environmentally activated, and context specific. It has been conceptualized as a multidimensional construct with five dimensions: instant enjoyment, exploration intention, attention demand, novelty, and challenge. Few prior studies have compared SI between girls and boys in physical education (PE) contexts, and these studies have offered contrasting findings. They were conducted in coeducational (coed) or single-sex contexts and used learning tasks centred on a variety of outcomes: technical or tactical skills, creativity and cultural understanding.

Purpose: In the context of the debate on single-sex and coed classes in PE, this study aimed to estimate the effects of single-sex and coed PE classes on students’ situational interest (SI) within learning tasks centred on technical skills. The researchers decided to study learning tasks centred on the development of students’ technical skills, since these tasks are often used by teachers in PE.

Participants: The sample consisted of 177 Swiss secondary school students, aged 11–17 years (M?=?14.07, SD?=?1.41, 96 boys, 81 girls).

Data collection: The students completed the French 15-item SI Scale after practising a technical learning task in single-sex and coed PE contexts. The researchers chose five physical activities (i.e. athletics, basketball, dance, gymnastics, and volleyball), which are commonly taught in the state of Vaud (Switzerland) and provide a balance between masculine and feminine activities.

Data analysis: A two-way repeated-measures MANOVA was performed to examine the main and interaction effects of student sex and class sex composition on the five SI dimensions.

Findings: The results showed a main effect of class sex composition on student SI but no main effect of student sex and no interaction effect of student sex and class sex composition. More precisely, the scores for three SI dimensions (i.e. instant enjoyment, exploration intention, and attention demand) were higher in the coed context than in the single-sex context.

Conclusions: This study encourages teachers to propose coed PE classes to enhance students’ motivation and engagement when practising learning tasks centred on technical skills. This study offers supplementary evidence of the teacher’s role in promoting student SI. Beyond accounting for students’ dispositional factors (e.g. sex), PE teachers can significantly impact students’ SI in technical learning tasks through instructional choices.  相似文献   

‘Operating on a Basis of Student Consent’: Peter Medway’s Work in Finding a Language     

Tony Burgess 《Changing English: An International Journal of English Teaching》2015,22(3):265-268

Written nearly 40 years ago, Peter Medway’s Finding a Language continues to be an arresting read, which offers a powerful vision of what might be possible in education. In this brief introduction, I set the work in context, referring to ideas that Pete engaged with and recalling a little of the times.  相似文献   

New insights into brazilwood lake pigments manufacture through the use of historically accurate reconstructions     

Tatiana Vitorino  Leslie Carlyle  Vanessa Otero 《文物保护研究》2016,61(5):255-273

A multi-analytical approach for the study of brazilwood and its lake pigments was carried out based on historically accurate reconstructions. Recipes for brazilwood lakes from the fifteenth century technical text Livro de como se fazem as cores and the Winsor & Newton nineteenth century colourman's archive were reproduced and compared. Both primary sources allowed for the successful preparation of brazilwood lake pigments with colours that vary from light pink to dark red. The main steps and ingredients for the manufacture of these pigments were common in both sources, particularly the addition of Al³⁺ in the form of alum, and calcium carbonate (chalk). Reconstructions revealed that the latter acts as a pH buffer and filler, controlling the pH at which the lake pigment precipitates. The main difference between the two sources is that the nineteenth century recipes give the quantities for all ingredients, the precise temperatures and time, and achieved higher relative pigment yields (75% versus 45%). Full chemical characterisation of the reconstructions provided detailed information on the individual steps in the pigment manufacture and revealed that the presence of calcium sulphate dihydrate (gypsum) in the final pigment was a result of its formation in situ. Infrared, reflectance, and fluorescence spectroscopy proved to be essential and complementary techniques: while infrared was used to characterise additives and binders, reflectance and fluorescence data were fundamental for identifying the chromophore. The pigments and paints produced can now be used as standards for the identification and investigation of brazilwood lake pigments found in artworks.  相似文献

Florida and Puerto Rico Secondary Science Teachers’ Knowledge and Teaching of Climate Change Science     

Benjamin C. Herman  Allan Feldman  Vanessa Vernaza-Hernandez 《International Journal of Science and Mathematics Education》2017,15(3):451-471

Misconceptions about climate change science are pervasive among the US public. This study investigated the possibility that these misconceptions may be reflective of science teachers’ knowledge and teaching of climate change science. Florida and Puerto Rico secondary science teachers who claim to teach extensively about climate change were surveyed in regard to their conceptions of climate change science and the climate change-related topics they teach. Results show that many teachers hold naïve views about climate change (e.g. that ozone layer depletion is a primary cause of climate change) and climate change science (e.g. that it must be based on controlled experiments for it to be valid). In addition, teachers in both groups neglect crucial topics such as how evidence for climate change is developed and the social, political, and economic dimensions of climate change. Our results suggest the need for teachers to understand how to teach climate change and the nature of climate change science using authentic contexts that promote effective socioscientific decision-making and climate change mitigation.  相似文献

A model for making decisions about ethical dilemmas in student assessment     

Robert L. Johnson  Jin Liu  Yin Burgess 《Journal of moral education》2017,46(2):212-229

In this mixed-methods study we investigated the development of a generalized ethics decision-making model that can be applied in considering ethical dilemmas related to student assessment. For the study, we developed five scenarios that describe ethical dilemmas associated with student assessment. Survey participants (i.e., educators) completed an online survey to express their decision-making process when faced with ethical dilemmas relating to student assessment. Based on the literature and the educators’ written responses to the scenarios, elements to consider in an ethics decision-making model related to student assessment include the following: (1) the critical incident giving rise to the ethical dilemma; (2) identification of the conflict elements; (3) decisions about the ethicality of the elements; (4) justification of the decisions; (5) implications; and (6) alternative suggestions. This model offers guidance to educators in considering the dimensions of an ethical dilemma in assessment prior to making a decision.  相似文献   

From Interaction to Intersubjectivity: Facilitating online group discourse processes     

Vanessa Paz Dennen  Kristina Wieland 《Distance Education》2007,28(3):281-297

This article examines the online discourse that took place in representative threads from two classes, seeking to document indicators that students did or did not engage in co‐construction of knowledge. Stahl's (2006 Stahl, G. 2006. Group cognition: Computer support for building collaborative knowledge, Cambridge, MA: MIT Press.  [Google Scholar]) social theory of computer supported collaborative learning (CSCL) is used along with discourse analysis methods to examine these course dialogues. Findings show the class that had a peer‐like, consistent facilitative instructor and discussion anchored around questions and shared artifacts was more likely to engage in discussion leading to the negotiation of knowledge and understanding. This class relied on social acknowledgements, questions, and shared exploration of perspectives and theories throughout their discussion. These elements and strategies appear to be important components that make up for lower levels of tacit understanding in online environments, thus enabling learners to interact in social learning processes. The other class, which lacked a facilitative instructor, did not have the same results. Although interaction levels were equal and students carried topical motifs such as the phrase “faster, better, cheaper” from message to message, students in this other class did not engage deeply or develop new understanding of the course material through the discussion.  相似文献
