Higher education needs to provide challenging yet supportive learning environments catering for students with diverse academic needs. There is also an emphasis on using student-driven outcome measures to determine teaching effectiveness. How can these measures be used to reflect upon and evaluate teaching initiatives? Using an undergraduate occupational therapy programme as the site for exploration, this article reports on an application of constructive alignment principles and describes how available empirical data were used to explore student outcomes. A comparison was made between student evaluations and academic grades prior to, and after the implementation of the initiative. Results provide evidence of improvement in student satisfaction and academic grades as a result of implementing constructive alignment. Whilst it is acknowledged that changes in academic grades and student evaluations can be attributed to a number of factors, findings of this study support a view that constructive alignment facilitates students' learning and experiences.  相似文献

ABSTRACT

Over the past couple of years, The New York Public Library has made significant strides in jumpstarting a digital humanities research program through the establishment of a curator-focused, R&D technology unit called NYPL Labs. This article will examine the first three projects produced by NYPL Labs, a trilogy of online experiments exploring methods of mining new humanities data sets from special collections material, and of translating the Library's public mission to the Web via user collaboration and crowdsourcing. In just two years, NYPL Labs has demonstrated how much can be accomplished when technical resources are focused and procedural constraints loosened, though the challenges of sustaining this work are already becoming apparent as the team must continue to innovate while maintaining a growing portfolio of projects.  相似文献

Business librarians can benefit from a deeper understanding of science and engineering resources, especially when researching technological topics, products, or industries. The authors introduce a variety of technical publications and databases useful for business research. Categories of resources described include technical encyclopedias and handbooks, periodical indexes and full-text databases, patents, technical reports, product literature, preprint and open-access repositories, conference proceedings, and dissertations. A case study based on MP3 audio technology demonstrates the types of business information that can be uncovered through a careful search of technical sources.  相似文献

Abstract

The aim of the present study was to examine, in highly trained young soccer players, the mechanical horizontal determinants of acceleration (Acc) and maximal sprinting speed (MSS). Eighty-six players (14.1 ± 2.4 year) performed a 40-m sprint to assess Acc and MSS. Speed was measured with a 100-Hz radar, and theoretical maximal velocity (V0), horizontal force (F0) and horizontal power (Pmax) were calculated. Within each age group, players were classified as high Acc/fast MSS (>2% faster than group mean), medium (between ?2% and +2%), and low/slow (>2% slower). Acc and MSS were very largely correlated (?0.79; 90% confidence limit [?0.85; ?0.71]). The determinants (multiple regression r2 = 0.84 [0.78; 0.89]) of Acc were V0 (partial r: 0.80 [0.72; 0.86]) and F0 (0.57 [0.44; 0.68]); those of MSS (r2 = 0.96 [0.94; 0.97]) were V0 (0.96 [0.94; 0.97]) and Pmax (0.73 [0.63; ?0.80]). High/Med have likely greater F0 (Cohen’s d: +0.8 [0.0; 1.5]), V0 (+0.6 [?0.1; 1.3]) and Pmax (+0.9 [0.2; 1.7]) than Low/Med. High/Fast have an almost certainly faster V0 (+2.1 [1.5; 2.7]) and a likely greater Pmax (+0.6 [?0.1; 1.3]) than High/Med, with no clear differences in F0 (?0.0 [?0.7; 0.6]). Speed may be a generic quality, but the mechanical horizontal determinants of Acc and MSS differ. While maximal speed training may improve both Acc and MSS, improving horizontal force production capability may be efficient to enhance sprinting performance over short distances.  相似文献
