The purpose of this study was to evaluate a technique known as collaborative assessment considering students' and faculty members' perceptions of the value and utility of this approach. Twenty-eight dental hygiene students took eight individual assessments (quizzes) immediately followed by completion of the same assessment in a five-member peer group as part of a didactic dental hygiene course. At the end of the semester, student perceptions and course performance were examined. Faculty perceptions were also collected. A paired samples t-test was conducted to compare student performance on individual and group assessments. Students reported that this collaborative assessment approach enhanced their learning, provided them with experience in defending their answers, and decreased stress. Concerns for fairness and individual accountability were noted by both students and faculty. The mean group score for all quizzes combined (M=91 percent, SD=2 percent) was significantly higher by 16 percentage points (91 percent versus 75 percent) than the mean individual score for all quizzes combined (M=75 percent, SD=8 percent), t(27)=11.61, α=.05, p<.0005. This study suggests that additional measures are needed to ensure individual preparation and accountability when using the collaborative assessment process as a learning strategy with dental hygiene students.

The purpose of this study was to evaluate the impact of collaborative learning on the development of social interaction, task management, and trust in dental hygiene students. These three traits were assessed with the Teamwork Assessment Scale in two different learning environments (traditional lecture/lab and collaborative learning environment). A convenience sample of ifty-six entry-level dental hygiene students taking an introductory/preclinic course at two metropolitan area dental hygiene programs provided comparable experimental and control groups. Factor scores were computed for the three traits, and comparisons were conducted using the Ryan-Einot-Gabriel-Welsh multiple comparison procedure among speciic cell comparisons generated from a two-factor repeated measures ANOVA. The results indicate that the collaborative learning environment inluenced dental hygiene students positively regarding the traits of social interaction, task management, and trust. However, comparing dental hygiene students to undergraduate students overall indicates that dental hygiene students already possess somewhat higher levels of these traits. Future studies on active learning strategies should examine factors such as student achievement and explore other possible active learning methodologies.
