The Effectiveness of Computer-assisted Instruction in Developmental Mathematics


Book Description

Colleges and universities are trying alternative instructional approaches to improve the teaching of developmental mathematics with the goal of increasing the number of students who have the skills and knowledge required for college-level math courses and for the twenty-first century workforce. Computers and the internet make possible new methods of delivering instruction so students will have choices of when, where, and how they learn math. The purpose of this study was to compare academic performance of students enrolled in a developmental mathematics course using traditional instruction, traditional instruction supplemented with computer-assisted instruction, and online distance learning. In addition, gender differences in mathematical performance were also investigated. The quasi-experimental study was conducted in Intermediate Algebra classes at a large, private, eastern university. An analysis of covariance was used to adjust the mean posttest scores for any initial difference in the groups on the pretest. There was no statistically significant difference in the posttest scores of students receiving traditional instruction and traditional instruction supplemented with computer-assisted instruction. There was a significant difference in the posttest scores of females and males, with females outperforming males in both modes of instruction. Although the original intent of this study was to include a group of students who took the course online, pretest scores for this group excluded them from the analysis. Institutions should offer developmental mathematics courses in a variety of formats, assist students in selecting the mode of instruction that best suits their learning style, and provide professional development in computer-assisted instruction.







Assessing the Impact of Computer-Based Instruction


Book Description

Can computer applications help improve student performance? For what skills, grade levels, content areas, and type of students are computer applications most effective? Can computer applications improve student attitude toward school and decrease drop-out rates? Discover what the research reveals--in this provocative new book--about these and other crucial questions concerning the impact of computer-based instruction. Assessing the Impact of Computer-Based Instruction provides the most comprehensive and up-to-date summary available on the effects of computer applications on both student achievement and attitudes. Within its pages are also the most extensive bibliography ever prepared on past reviews of research, current reports and articles, and dissertations in the area of computer uses in education. This groundbreaking new book provides educational decisionmakers with the facts they need in order to justify the expense and effort of maintaining and expanding the instructional role of computers in schools. It is also useful as a resource text in the pre-service training of computer educators and for graduate students doing research in instructional computing.
