Globetrotting Students and Faculty: Adapting Library Instruction to Global Sites

ABSTRACT

As e-resources become more ubiquitous, and the technologies available to access them more sophisticated, libraries have greater opportunities to reach out to global users. However, this same distance means that some users never even set foot in a physical library. This case study will describe how one large academic library started a business, economics, and marketing library online instruction pilot for global users in an effort to replicate library instruction offered at the home institution. Librarians assessed global library use and research needs; prepared unique lesson plans for each global site; and created digital learning objects using synchronous and asynchronous methods to establish an instruction strategy for Business and Economics courses. The goal was to test instruction practices and develop an online instruction template that would be replicable and sustainable for library instruction in other subject areas in New York University Libraries and other institutions.     

媒介与文学

The effectiveness of machine score-ability ratings in predicting automated scoring performance

ABSTRACT

This study sought to provide a framework for evaluating machine score-ability of items using a new score-ability rating scale, and to determine the extent to which ratings were predictive of observed automated scoring performance. The study listed and described a set of factors that are thought to influence machine score-ability; these factors informed the score-ability rating applied by expert raters. Five Reading items, six Science items, and 10 Math items were examined. Experts in automated scoring served as reviewers, providing independent ratings of score-ability before engine calibration. Following the rating, engines were calibrated and their performances were evaluated using common industry criteria. Three derived criteria from the engine evaluations were computed: the score-ability value in the rating scale based on the empirical results, the number of industry evaluation criteria met by the engine, the approval status of the engine based on the number of criteria met. The results indicated that the score-ability ratings were moderately correlated with Science score-ability, the ratings were weakly correlated with Math score-ability, and were not correlated with Reading score-ability.
