The Library According to Mary

This blog is about my experiences in the Educational Technology Ed.D program at the University of Florida. Please feel free to contact me with questions or comments. My interests include the intersection of libraries, education, and technology and their effect on distance education. I'm also exploring the concept of multiple literacies, including how media, visual, and information literacy relate and the implications for libraries.

No Significant Difference

I read "Effects of Computer-Assisted Instruction on Cognitive Outcomes: A Meta-Analysis" to gain insight into the "No Significant Difference" debate.

Liao, Yuen-Kuang. (1992). "Effects of Computer-Assisted Instruction on Cognitive Outcomes: A Meta-Analysis". Journal of Research on Computing in Education, 24(3), 367-380.

The author (Liao) performed a meta-analysis of 31varticles studying the effects of CAI on cognitive outcomes. To conduct his analysis, Liao calculated "Effect Size" (ES) scores for each study. 74% of the ES's indicated that cognitive ability scores were higher for the CAI group. Liao concluded that his study had a significant impact on the mean ES and that CAI is somewhat effective for teaching cognitive skills. The author points out that his study didn't determine whether CAI is as or more efficient at developing cognitive skills than other forms of instruction.

I'll post more discussion about this article tomorrow, when I'm not drowsy from the Nyquil I took so I can get some sleep with this cold.

Hi Mary!
Good job on your presentation. Information literacy is something that I've never really thought about, and I learned a lot from your presentation. Using the TILT website was a great activity. Your flash animation is quite amusing as well ;-)
