Direct assessment as a measure of institutional effectiveness in a dental hygiene distance education program.

This ten-year, longitudinal examination of a dental hygiene distance education (DE) program considered student performance on standard benchmark assessments as direct measures of institutional effectiveness. The aim of the study was to determine if students face-to-face in a classroom with an instructor performed differently from their counterparts in a DE program, taking courses through the alternative delivery system of synchronous interactive television (ITV). This study used students' grade point averages and National Board Dental Hygiene Examination scores to assess the impact of ITV on student learning, filling a crucial gap in current evidence. The study's research population consisted of 189 students who graduated from one dental hygiene program between 1997 and 2006. One hundred percent of the institution's data files for these students were used: 117 students were face-to-face with the instructor, and seventy-two received instruction through the ITV system. The results showed that, from a year-by-year perspective, no statistically significant performance differences were apparent between the two student groups when t-tests were used for data analysis. The DE system examined was considered effective for delivering education if similar performance outcomes were the evaluation criteria used for assessment.
