This paper addresses the lack of evaluative resources for computer-assisted reading and writing instruction (CARWI). It begins by discussing the benefits, drawbacks, and effectiveness of computer-based instruction. It then describes types of CARWI packages, including: (1) writing process software; (2) electronic handbooks; (3) interactive exercises; (4) comprehensive language programs; and (5) online writing labs (OWLs) and online reading labs. It continues by discussing cost, convenience, attractiveness, and effectiveness, which are the factors to consider when selecting CARWI programs. It then describes two Web sites developed by the author to solicit and post descriptions and user testimonials of software packages used in writing centers nationally. The author also suggests a numeric rating method to evaluate the results of such questionnaires and concludes by discussing the advantages of CARWI. (EF)
