Development and testing of self-instruction programs in nutrition for dental students

Area of Science:

• Dental Education
• Medical Education Technology

Background:

• Traditional lectures are a common method for delivering nutrition and dentistry education.
• The effectiveness of self-instructional programs as an alternative teaching method requires evaluation.

Purpose of the Study:

• To compare the effectiveness of self-instructional programs versus traditional lectures for teaching nutrition and dentistry.
• To evaluate learning outcomes and student attitudes towards different teaching modalities.

Main Methods:

• Developed five programmed self-instructional manuals with 191 slides.
• Compared these materials to six traditional lectures covering the same content.
• Randomly assigned 83 freshmen dental students into control (lecture) and experimental (self-instruction) groups.
• Assessed learning via cognitive tests, diet counseling performance, and attitudinal questionnaires.

Main Results:

• Analysis revealed no statistically significant differences in cognitive test scores between the lecture and self-instruction groups.
• Performance criteria and attitudinal data also indicated comparable outcomes between the two educational approaches.

Conclusions:

• Self-instructional programs are a viable and effective alternative to traditional lectures for nutrition and dentistry education in dental schools.
• Educational technology, such as programmed manuals and slides, can achieve similar learning outcomes to conventional lecture formats.
