title: Use of questioning during lectures in a dental hygiene didactic course.
abstract: The purposes of this quasi-experimental, one-group crossover study were to determine the effect of questioning during dental hygiene lectures on low-level and high-level learning and to evaluate student perceptions of questioning. Twenty-three dental hygiene students participated in two control lectures using traditional lecturing methods. The students served as their own controls by next participating in two experimental lectures with questions asked throughout the lecture at both low and high cognitive levels. Student performance was measured with an examination containing low- and high-level questions. The interaction between the group and the level of questions was analyzed using ANOVA, and no statistically significant difference was found. Based on a Likert scale (1 to 6), average ratings for student perceptions were as follows: enjoyment of use, 4.5; understanding the lecture material, 4.74; and questioning effectiveness, 4.35. Student perceptions of questioning were positive; however, this strategy was found to be no more effective than the traditional lecture in promoting retention of information.
