A method of providing accurate velocity feedback of performance on an instrumented kayak ergometer     

Mickaël Begon  Olivier Mourasse  Patrick Lacouture 《Sports Engineering》2009,11(2):57-65

On a kayak ergometer, an accurate simulation of the athlete-paddle-kayak system kinematics is essential for analysing the relationship between technique and performance. The purpose of this study was to establish a strong relationship between performances on flatwater and performances on an ergometer by means of propulsive force measurement and drag models. Two trials were performed by 12 kayakers in which they were first timed over 250 m of flatwater kayaking (the reference test) and were then asked to perform a trial of the same duration on the ergometer with the same perceived physical exertion. Three techniques for measuring propulsive force and three drag models generated nine combinations, which were all evaluated for their ability to estimate kayak velocity. For each combination, the distance covered by the athlete on the ergometer was simulated. A kayakers’ ergometer ranking was based on the average velocity in the ergometer trial. Both distance and ranking were compared to the on-water results. The simulation with the best combination of force measurement and drag model gave an accurate estimate of distance (253 ± 10.5 vs. 250 m) and ranking compared to the reference test.  相似文献   

Evaluating a monolingual multinational digital library by using usability: An exploratory approach from a developing country     

lvaro Quijano-Solís  Raúl Novelo-Pea 《International Information and Library Review》2005,37(4):329

In this paper the authors present a preliminary discussion on some of the results from a survey aimed to explore, describe and explain some of the usability characteristics in digital libraries evaluation in the Mexican context. The study is framed in the evaluation of a multinational and monolingual digital library: the Miguel de Cervantes Virtual Library, from the University of Alicante in Spain. The evaluators were Mexican “expert” users (i.e. Spanish-speaking professional university librarians specialized in electronic reference services) who were asked to carry on an evaluation instrument based on usability criteria as taken from some models in developed countries. Some questions that might be answered with future research are outlined in this paper.  相似文献

The Co-Effects of Query Structure and Expansion on Retrieval Performance in Probabilistic Text Retrieval     

Jaana Kekäläinen  Kalervo Järvelin 《Information Retrieval》2000,1(4):329-344

The effects of query structures and query expansion (QE) on retrieval performance were tested with a best match retrieval system (InQuery¹). Query structure means the use of operators to express the relations between search keys. Six different structures were tested, representing strong structures (e.g., queries with facets or concepts identified) and weak structures (no concepts identified, a query is a bag of search keys). QE was based on concepts, which were first selected from a searching thesaurus, and then expanded by semantic relationships given in the thesaurus. The expansion levels were (a) no expansion, (b) a synonym expansion, (c) a narrower concept expansion, (d) an associative concept expansion, and (e) a cumulative expansion of all other expansions. With weak structures and Boolean structured queries, QE was not very effective. The best performance was achieved with a combination of a facet structure, where search keys within a facet were treated as instances of one search key (the SYN operator), and the largest expansion.  相似文献   

Validation of the Instructional Materials Motivation Survey (IMMS) in a self‐directed instructional setting aimed at working with technology          下载免费PDF全文

The ARCS Model of Motivational Design has been used myriad times to design motivational instructions that focus on attention, relevance, confidence and satisfaction in order to motivate students. The Instructional Materials Motivation Survey (IMMS) is a 36‐item situational measure of people's reactions to instructional materials in the light of the ARCS model. Although the IMMS has been used often, both as a pretest and a posttest tool serving as either a motivational needs assessment prior to instruction or a measure of people's reactions to instructional materials afterward, the IMMS so far has not been validated extensively, taking statistical and theoretical aspects of the survey into account. This paper describes such an extensive validation study, for which the IMMS was used in a self‐directed instructional setting aimed at working with technology (a cellular telephone). Results of structural equation modeling show that the IMMS can be reduced to 12 items. This Reduced Instructional Materials Motivation Survey IMMS (RIMMS) is preferred over the original IMMS. The parsimonious RIMMS measures the four constructs attention, relevance, confidence and satisfaction of the ARCS model well, and reflects its conditional nature.  相似文献   

What and how teacher educators prefer to learn     

Jurriën Dengerink  Mieke Lunenberg  Quinta Kools 《师资教育杂志》2015,41(1):78-96

In which areas and domains do individual teacher educators prefer to work on their professional development? What kind of learning activities do they want to take on and with whom? Are there significant differences in these preferences between teacher educators? This article reports on a recent survey (N = 268) about the professional development of teacher educators and differences in learning preferences between less and more experienced teacher educators and between university-based and school-based teacher educators. Findings show, for example, that while most university-based teacher educators were mainly interested in improving their teaching, less experienced school-based teacher educators were more focussed on aspects such as coaching skills. In this study, ‘learning profiles’ have been developed for four categories of teacher educators. These profiles may help to create more meaningful arrangements for teacher educators’ initial education and further professional development in a context where teacher education is required to have a more school-based as well as a more research-based orientation.  相似文献   

Significant networks and meaningful conversations observed in the first-round applicants for the Teachers’ Academy at a research-intensive university     

Eeva Pyörälä  Laura Hirsto  Auli Toom  Liisa Myyry  Sari Lindblom-Ylänne 《International Journal for Academic Development》2015,20(2):150-162

The University of Helsinki established a Teachers’ Academy to reward excellence in teaching. This study focuses on teachers’ significant networks and their meaningful conversations about teaching and learning before the establishment of the Teachers’ Academy. The research data consisted of answers to open-ended questions, and were examined using social network analysis. The teachers’ network consisted of significant relations with (1) colleagues and other teachers, (2) peers in pedagogical courses and pedagogical experts, (3) students, and (4) family members and friends. The conversations with different parties varied in nature, content and the level of confidentiality.  相似文献
