Using a Web-Based Simulation as a Problem-Based Learning Experience: Perceived and Actual Performance of Undergraduate Public Health Students

Abstract

SYNOPSISObjectives. This study investigated the use of a Web-based community health simulation as a problem-based learning (PBL) experience for undergraduate students majoring in public health. The study sought to determine whether students who participated in the online simulation achieved differences in academic and attitudinal outcomes compared with students who participated in a traditional PBL exercise.Methods. Using a nonexperimental comparative design, 21 undergraduate students enrolled in a health-behavior course were each randomly assigned to one of four workgroups. Each workgroup was randomly assigned the semesterlong simulation project or the traditional PBL exercise. Survey instruments were used to measure students' attitudes toward the course, their perceptions of the learning community, and perceptions of their own cognitive learning. Content analysis of final essay exams and group reports was used to identify differences in academic outcomes and students' level of conceptual understanding of health-behavior theory.Results. Findings indicated that students participating in the simulation produced higher mean final exam scores compared with students participating in the traditional PBL (p50.03). Students in the simulation group also outperformed students in the traditional group with respect to their understanding of health-behavior theory (p50.04). Students in the simulation group, however, rated their own level of cognitive learning lower than did students in the traditional group (p50.03).Conclusions. By bridging time and distance constraints of the traditional classroom setting, an online simulation may be an effective PBL approach for public health students. Recommendations include further research using a larger sample to explore students' perceptions of learning when participating in simulated real-world activities. Additional research focusing on possible differences between actual and perceived learning relative to PBL methods and student workgroup dynamics is also recommended.

An Exploration Of The Effectiveness Of An Audit Simulation Tool In A Classroom Setting

“…In higher education simulations have been utilized in a vast and diverse number of disciplines such as, physics (Dori & Belcher, 2005), supply change management (Zeng & Johnson, 2009), economics (Porter, Riley, & Ruffer, 2004), higher education administration (Prisk & Dunn, 2002), public health (Spinello & Fischbach, 2008), and civil engineering (Chen & Levinson, 2006). Dori and Belcher, 2005, developed the Technology Enabled Active Learning (TEAL) Project at MIT.…”

The Foodborne Outbreak Challenge—Using Experiential Learning to Foster Interdisciplinary Training Among Students on Foodborne Disease Outbreak Investigations

“…In this real‐world environment, learners applied their knowledge and personal prior experiences at a macro‐level perspective, rather than focusing on individual pieces, such as the steps in an outbreak investigation. Similar experiential and problem‐based learning activities have been shown to increase self‐motivation, analytical thinking, and long‐term retention (Spinello and Fischbach , ; Ali and others ; Barrett and others ).…”

Taxonomy of interactive computer-based visualisation systems and content for the mining industry – part 2

“…Stone and Knight (2012) discuss military applications where human factors issues are considered in great detail. Wang (2013) discusses possible construction simulator formats and application, Spinello and Fischbach (2008) Oculus (2014), is revisiting VR headsets, a technology abandoned by earlier mining VR researchers in the 1990s and 2000s. However, the human factors considerations discussed by Stone (2008) and Stone and Knight (2012), in particular those design elements that may contribute to malaise or ''cybersickness'' and whether or not stereoscopic image display within VR headsets is actually effective or, indeed, warranted, still apply to these devices and to those predicted for market release within the next couple of years.…”
