Introductory Nutrition Computer Course for Traditional and Nontraditional Students (including UA Collaboration with CAC)

Society-Ready Graduates
Research Year: 

Completing a college degree in a reasonable time span is a challenge for both traditional and nontraditional students. Many students must work, raise families, or complete internships while working on their degree. Distance education facilitates timely degree completion for students so they can pursue their profession.

Description of Action: 

The UA College of Agriculture and Life Sciences Nutritional Science Department and Distributed Learning Lab created a distributed an interactive, student-centered introductory nutrition course that uses a website and CD-ROMs. A campus server hosts course-management software for course communication, interactive exercises and testing. The CD-ROMs contain an extensive textbook outline, a full semester's-worth of short video clips of course lectures given during the classroom-delivered course, animations, a glossary, and links to the Internet. The course is offered as an elective course or can fulfill a Tier I Biological Science General Education requirement. Students can enroll through traditional methods as a University of Arizona student, through Extended University, or through Central Arizona College. An orientation meeting is held at the beginning of each term or students can obtain start-up instructions electronically.


The total number of students completing the nutrition course between 1998 and 2002 from the convenience of their own computers was 2173. The course was first offered during fall 1998 with 30 students. The number has increased steadily since then, with 1,000 students completing the course in 2002. The course is scheduled to be offered during spring, summer and winter sessions 2003, with 380 enrolled as of January 2003. The department has evaluated the effectiveness of offering these distributed courses by comparing performance of the online students to those taking the course in a traditional classroom. No difference was found in exam scores, final grades, or between pretest and post-test scores for the two learning environments. The program fulfills one of the Arizona Board of Regents priorities: to expand access to the university.
