title: Distance education outcomes in clinical laboratory science.
abstract: OBJECTIVE
  To compare 2 types of delivery methods for clinical laboratory science students-the technology-driven method at distance sites versus the on-site method on campus-in terms of learning outcomes.
  
  
  METHODS
  The independent variable in this quasi-experimental study was the delivery method consisting of interactive videoteleconferencing and on-site classroom methods. The dependent variables were learning outcomes that were determined by 2 methods: the average score on 8 posttests scheduled at periodic intervals and a national certification examination score.
  
  
  METHODS
  Clinical laboratory science (CLS) education program at the University of Nebraska Medical Center in Omaha and at 6 clinical sites in other cities across Nebraska.
  
  
  METHODS
  40 senior CLS students enrolled in a baccalaureate degree program. Control group participants were assigned to 2 clinical sites in the Omaha area, and the experimental group were assigned to 6 distant clinical sites.
  
  
  METHODS
  Data analysis consisted of descriptive statistics, 2-way analysis of variance (ANOVA), 2-way analysis of covariance (ANCOVA), repeated measures analysis of variance, and Hotellings T2.
  
  
  RESULTS
  Results showed no significant difference between the students' examination scores based on delivery method (p > 0.05), except in the chemistry topic area. There was no significant difference in the pattern of the examination scores over the semester of learners who were instructed by interactive videoteleconferencing methods and learners who were instructed by on-site classroom methods.
  
  
  CONCLUSIONS
  Results of the study generally support the use of interactive videoteleconferencing as an effective, alternative delivery method for CLS students who cannot attend class on campus. Analysis by topic areas suggests that additional studies are needed to validate the variance found in the chemistry subject area.
