An evaluation of computer-based instruction in microbiology.

Area of Science:

• Microbiology Education
• Educational Technology

Background:

• Computer-based instruction (CBI) materials have increased, with some studies suggesting learning improvements.
• Concerns exist regarding the adequacy of current research on CBI effectiveness in classroom settings.
• Educators need to evaluate if CBI materials genuinely enhance student learning.

Purpose of the Study:

• To evaluate a computer-based hypermedia tutorial for General Microbiology delivered via a website.
• To compare the effectiveness of CBI with traditional text-based learning materials.
• To identify factors influencing student benefit from CBI.

Main Methods:

• A computer-based hypermedia tutorial was developed and delivered through a General Microbiology website.
• Student usage of the CBI tutorial was tracked.
• Learning outcomes were compared between students using CBI and those using text-based materials.

Main Results:

• The CBI tutorial was found to be at least as effective as text-based materials.
• Only students who extensively explored the CBI hypermedia tutorial showed significant benefits.
• Tracking student interaction with the CBI was crucial for interpreting learning gains.

Conclusions:

• Computer-based hypermedia tutorials can be effective learning tools in microbiology.
• Student engagement and depth of interaction with CBI are critical for realizing learning benefits.
• Monitoring student usage patterns is essential for assessing the efficacy of CBI in educational contexts.
