The utility of adaptive eLearning data in predicting dental students' learning performance in a blended learning course.

Objectives: To examine the impact of dental students' usage patterns within an adaptive learning platform (ALP), using ALP-related indicators, on their final exam performance. Methods: Track usage data from the ALP, combined with demographic and academic data including age, gender, pre- and post-test scores, and cumulative grade point average (GPA) were retrospectively collected from 115 second-year dental students enrolled in a blended learning review course. Learning performance was measured by post-test scores. Data were analyzed using correlation coefficients and linear regression tests. Results: The ALP-related variables (without controlling for background demographics and academic data) accounted for 29.6% of student final exam performance (R2=0.296, F(10,104)=4.37, p=0.000). Positive significant ALP-related predictors of post-test scores were improvement after activities (ß=0.507, t(104)=2.101, p=0.038), timely completed objectives (ß=0.391, t(104)=2.418, p=0.017), and number of revisions (ß=0.127, t(104)=3.240, p=0.002). Number of total activities, regardless of learning improvement, negatively predicted post-test scores (ß= -0.088, t(104)=-4.447, p=0.000). The significant R2 change following the addition of gender, GPA, and pre-test score (R2=0.689, F(13, 101)=17.24, p=0.000), indicated that these predictors explained an additional 39% of the variance in student performance beyond that explained by ALP-related variables, which were no longer significant. Inclusion of cumulative GPA and pre-test scores showed to be the strongest and only predictors of post-test scores (ß=18.708, t(101)=4.815, p=0.038) and (ß=0.449, t(101)=6.513, p=0.038), respectively. Conclusions: Track ALP-related data can be valuable indicators of learning behavior. Careful and contextual analysis of ALP data can guide future studies to examine practical and scalable interventions.

Sleep-Disordered Breathing among Saudi Primary School Children: Incidence and Risk Factors.

This study aimed to identify the incidence and risk factors of sleep-disordered breathing (SDB) using an Arabic version of the pediatric sleep questionnaire (PSQ). A total of 2000 PSQs were circulated to children aged 6-12 years who were randomly selected from 20 schools in Al-Kharj city, Saudi Arabia. The questionnaires were filled out by the parents of participating children. The participants were further divided into two groups (younger group: 6-9 years and older group: 10-12 years). Out of 2000 questionnaires, 1866 were completed and analyzed (93.3% response rate), of which 44.2% were from the younger group and 55.8% were from the older group. Among all the participants, a total of 1027 participants were female (55%) and 839 were male (45%) with a mean age of 9.67 ± 1.78 years. It showed that 13% of children were suffering from a high risk of SDB. Chi-square test and logistic regression analyses within this study cohort showed a significant association between SDB symptoms (habitual snoring; witnessed apnea; mouth breathing; being overweight; and bedwetting) and risk of developing SDB. In conclusion: habitual snoring; witnessed apnea; mouth breathing; being overweight; and bedwetting strongly contribute the to development of SDB.

Comparison between two asynchronous teaching methods in an undergraduate dental course: a pilot study.

BACKGROUND: Properly designed and implemented eLearning can lead to improvement of dental teaching quality. Various strategies have been proposed to increase the effectiveness of eLearning in dental education, however, there is a lack of research to assess the effectiveness of these strategies. OBJECTIVE: To investigate dental students' learning performance and perception of a virtual flipped learning format compared to a virtual traditional learning method. METHODS: A crossover pilot study was conducted at the College of Dentistry, Princes Sattam Bin Abdulaziz University, Saudi Arabia. Computer-generated randomization, blinded from researchers who analyzed the results, was performed to allocate 32 participants (aged 23.27 ± 0.86 years) to one of two groups. Participants in the control group were taught through the virtual traditional learning method (VTL) using live video lectures. In contrast, participants in the intervention group were taught through the virtual flipped learning method (VFL) using recorded online lectures and post-lecture virtual discussions. Learning gain and preference were measured by pre- and post-test average score differences and a modified validated survey, respectively. RESULTS: There was no significant difference in learning performance between VFL and VTL groups (P > 0.05). However, students preferred VFL over VTL and the differences were significant among all survey items, except for the opportunity to ask questions. CONCLUSION: Health professions educators are encouraged to carefully design online curricula with efficient learning strategies that help students improve learning performance and foster self-directed learning skills while valuing active learning in an online environment.

Parental Satisfaction with Their Children's Rapid Palatal Expansion Treatment Provided by Orthodontists and Pediatric Dentists.

BACKGROUND: Dentofacial problems have a definitive impact on patients' psychological well-being, quality of life, and satisfaction. Therefore, patients' satisfaction with their dentition should be an essential goal for dental caregivers. AIM: To compare parental satisfaction with their children's rapid palatal expansion treatment outcome provided by orthodontists and pediatric dentists. MATERIALS AND METHODS: The authors reviewed 605 medical records and contacted 134 parents whose children received early orthodontic treatment from orthodontists and pediatric dentists using a rapid palatal expander. Eighty-eight parents (65.7%) responded to a validated questionnaire about patients' satisfaction with orthodontic treatment outcomes. RESULTS: At baseline; there were no significant differences in relation to parent-related demographic variables. However, there were statistically significant differences between patients' ages and treatment duration (p < 0.001). Independent t-tests showed statistically significant differences in the means for the subscales of doctor-patient relationship and situational aspects (p < 0.05). Spearman's rho correlation coefficients and multivariate linear regression analysis showed that the overall satisfaction is significantly related to, and can be predicted by, parents' educational level, child's gender, and the specialty of the dentist who provided the treatment (p < 0.05). CONCLUSION: Overall parental satisfaction with their children's rapid palatal expansion treatment is significantly higher when provided by pediatric dentists as compared with orthodontists. Factors related to doctor-patient relationship and situational aspects (ie, office location and design, appointment waiting, and treatment duration) significantly impacted parental satisfaction.

Effectiveness of an adaptive eLearning intervention on dental students' learning in comparison to traditional instruction.

There is a great deal of excitement in higher education about the value of adaptive learning to personalize learning paths according to students' individual needs. The authors explored the impact of an Adaptive Learning Platform (ALP) on learning, by comparing learning effectiveness between dental students who used the ALP in a blended learning environment formatively and summatively compared with students who did not use the ALP (i.e., face-to-face), as measured by students' performance on the final exam in a single review preparatory course during the academic years 2013-2018. Paired t-tests showed significant improvement in post-test scores across different course instructional modalities (P < 0.01). The learning gain was greater for students who studied using the ALP summatively (t = 26.20) than those who used it formatively or studied using a face-to-face format (t = 13.10 and 14.13, respectively). Controlling for pre-test scores, analysis of covariance tests indicate that: (1) intervention groups (formative and summative ALP) scored significantly higher than the traditional group (B = 9.34 points, P < 0.01, for summative ALP group) and (B = 4.47 points, P < 0.05, for formative ALP group), and (2) summative ALP group scored significantly higher than formative ALP group (B = 4.84 points, P < 0.05). This study provides empirical evidence that an adaptive learning intervention can have a significant impact on student learning performance. The success of any adaptive learning system relies mainly on sound instructional design. Technology will continue to grow at an overwhelming pace; the cautionary note the authors highlight is that conceptions of pedagogy, complemented by technology, must guide the development of adaptive learning systems.
