The study compared basic and elaborated corrections within the context of otherwise identical computer-assisted instruction (CAI) programs that taught reasoning skills. Twelve learning disabled and 16 remedial high school students were randomly assigned to either the basic-corrections or elaborated-corrections treatment. Criterion-referenced test scores were significantly higher for the elaborated-corrections treatment on both the post and maintenance tests and on the transfer test. Time to complete the program did not differ significantly for the two groups.
Depressed economic times often lead libraries to consider new practices, including alternatives to the traditional subscription model. This column discusses a pay-per-view (PPV) model for acquiring journal articles whereby a library creates an account with a content provider through which authenticated users can purchase articles at the library's expense. To gain insight into the current use of this model, the paper draws on both a literature review and the results of a survey assessing the practices of academic libraries with experience acquiring articles through unmediated, user-initiated pay-per-view transactions. The future of the PPV model as well as issues and challenges that it raises are also considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
