Professors who wish to implement problem‐based learning (PBL) must reconcile numerous tensions regarding its efficacy. The authors address some of these tensions by considering empirical literature about PBL.

The aim of this study was to discover how an active learning classroom (ALC) influenced the teaching and learning of dental radiology with dental hygiene students through a mixed‐methods approach. A year‐long observation of a dental hygiene professor who was teaching two consecutive courses in an ALC was conducted in 2015–16. Nineteen classes were recorded and transcribed, and observational notes on classroom activities were taken. Towards the end of the academic year, the professor was interviewed with use of a 13‐question guide, and the students were surveyed with a 25‐question survey. Moreover, five‐year grades in the same two courses, including four‐year historical grades earned in the traditional classrooms (TCs) and one year from the ALC, were collected along with demographic and prior academic performance data. Thirty‐two of the 38 students responded to the survey, for a response rate of 84%. The results showed that 63% of the students preferred to take classes in the ALC rather than TC. They especially enjoyed the ALC's spaciousness, mobility, unobstructed views, and ease of information‐sharing and engagement in class. However, the ALC presented both the faculty and students with sensory and technique challenges. The analysis of students' grades suggested that GPA was one of the strongest predictors for both courses' final grades in the TCs but had weaker predicting significance in the ALC setting. Overall, the majority of students enjoyed taking classes in the ALC due to its physical charm and dynamic collaboration. Sensory and technique challenges coexisted with benefits.

In recent years, many institutions have transformed traditional classrooms (TCs) into technology-rich active learning classrooms (ALCs) to accommodate the pedagogical concept of "active learning". In order to investigate the impact of ALCs on teaching and learning, we observed an instructor teaching in an ALC for an entire academic year, audio/video-recorded every class and took field notes. A focus group discussion was conducted with faculty from six allied health disciplines who taught weekly classes in the ALC and an online survey was distributed to students who took those classes. Data was then analysed using a qualitative constant comparative method (CCM). Findings indicated that the ALC generated greater teaching and learning enjoyment, deepened engagement, amplified interaction, enhanced group activity efficiency and fostered the development of creative ideas. All these features were interrelated and created a synergistic effect on student learning.

Active learning space emerged at the turn of the twenty-first century. The active learning space design represents not only an overhaul of traditional classrooms’ physical appearances but also reflects a paradigm shift from teacher-centered learning to student-centered learning. Current available research mainly focused on student academic performance as well as student and faculty perceptions.  No research has been conducted to investigate interactions at the student level to find out what interactions are taking place in the active learning space and how they affect student learning. This study employed a sequential exploratory mixed-methods design inquiring into student learning in an active learning space first through student focus group discussions and then with an online student survey. The major themes emerged from the focus group discussions were utilized to develop the online survey. The purpose of this survey was to cross-validate qualitative outcomes and further seek answers to unanswered questions triggered by qualitative findings. The qualitative data indicated that the spatial equity in the active learning space put students in positive mindsets and induced active classroom participation. The interconnected screens made it easy for students to view class content and collaborate with peers. The group work conducted in the space fostered mutual learning, promoted learning accountability and improved peer relations. The quantitative survey data on group dynamics validated and reinforced qualitative findings. This paper will help educators better understand student behaviors in the active learning space and better design space-appropriate pedagogical strategies.

This study investigated the knowledge and training of dental professionals to competently serve persons with spinal cord injuries (SCI). Fifty dental clinics were approached to complete a survey containing questions regarding their special needs training. From the 35 completed surveys, descriptive quantitative data were analyzed. The majority of professionals reported minimal exposure to special needs dentistry during their academic training. Further analysis revealed a lack of expertise in wheelchair transfers or knowledge of possible medical complications. This study suggests that additional training is needed if dental professionals are to comfortably and safely care for patients with SCI.
