The Complier Average Causal Effect (CACE) method has been increasingly used in prevention research to provide more accurate causal intervention effect estimates in the presence of noncompliance. The purpose of this study was to provide an applied demonstration of the CACE analytic approach to evaluate the relative effects of a family-based prevention intervention, Familias Unidas, in preventing...

In this paper we are going to show how to discover interesting prediction rules in student usage information, and use them to improve adaptive web courses. We have used AHA! to make a course that adapts both the presentation and the navigation depending on the level of knowledge that each particular student has. We have made several changes in AHA! to improve its power in the educational area. ...

In the paper we describe the applicability of different types of resources and activity modules in the e-learning courses and the worthiness of their usage. The presented ideas are supported by the outcomes of the questionnaire research realized within the elearning study as well as the usage analysis of particular e-course ―Role of a nurse in community care‖ which was one of the outcomes of th...

Current approaches to measuring people's everyday usage of technology-based media and other computer-related activities have proved to be problematic as they use varied outcome measures, fail to measure behavior in a broad range of technology-related domains and do not take into account recently developed types of technology including smartphones. In the present study, a wide variety of items, ...

This paper presents some experiences in the exploitation of a database interface development architecture in which the interface is implemented using the facilities of the database. It is shown how novel interfaces, specifically a multiparadigm query interface and a debugger for an active rule system, can benefit from and exploit the uniform representation of interface and database system conce...

Recent studies have suggested that educators should avoid concrete instantiations when the goal is to promote transfer. However, concrete instantiations may benefit transfer in the long run, particularly if they are “faded” into more abstract instantiations. Undergraduates were randomly assigned to learn a mathematical concept in one of three conditions: generic, in which the concept was instan...
