2. First Study: Significant Difference
• Study title:
Teaching with ALN Technology: Benefits and Costs
• Author:
Kashy, D. A., Albertelli, G., Kashy, E., & Thoenne
• Appear in the:
Journal of Engineering Education, October 2001
• Result:
• "Even with higher course standards for success, student performance on
examinations has improved, a larger fraction of students achieve the goals of
the class, and the proportion of students who excel has increased. Female
students benefit even more than their male counterparts. The level of
communication and interaction among students has also increased
dramatically, with mostly positive (but some negative)effects. Data concerning
cost effectiveness indicate that the technology can reduce costs, but perhaps
more importantly, it can increase the quality without increasing costs."
3. Second study: No Significant
Difference
• Study title:
Effects of the Hyper textual Approach Versus the
Structured Approach on Students' Achievement.
• Author:
Lanza, A. & Roselli, T.
• Appear in the:
Journal of Computer-Based Instruction
• Result:
Both groups performed equally well, but the hypertext
group exhibited greater variability in
achievement, prompting the conclusion that hypertext
might be better suited to more able students."
