Technology in Public Health Higher Education

Streamed and recorded lectures as well as audience response technology are increasingly used in public health tertiary education, to train practitioners to address Asia-Pacific region's rapidly changing health needs. However, little is known about the impact on student performance, satisfaction, and understanding. This study aimed to assess postgraduate students' perceptions and their use of technology in a large epidemiology subject at an Australian university in internal and external modes. The study used both routinely collected student data (n = 453) and survey data (n = 88). Results indicate that students accept and use technology-based learning tools, and perceive audience response technology as well as streamed and recorded lectures as useful for their learning (96.6%). Students have shown a preference to review recorded lectures rather than viewing streamed lectures. Analyses further suggest that the use of recorded and streamed lectures may be linked to better student performance for external students (passing, any use odds ratio = 3.32). However, these effects are not consistent across all student subgroups and externally enrolled students may profit more than those enrolled internally.

A Mock Randomized Controlled Trial With Audience Response Technology for Teaching and Learning Epidemiology

The study’s objective was to apply and assess an active learning approach to epidemiology and critical appraisal. Active learning comprised a mock, randomized controlled trial (RCT) conducted with learners in 3 countries. The mock trial consisted of blindly eating red Smarties candy (intervention) compared to yellow Smarties (control) to determine whether red Smarties increase happiness. Audience response devices were employed with the 3-fold purposes to produce outcome data for analysis of the effects of red Smarties, identify baseline and subsequent changes in participant’s knowledge and confidence in understanding of RCTs, and assess the teaching approach. Of those attending, 82% (117 of 143 learners) participated in the trial component. Participating in the mock trial was a positive experience, and the use of the technology aided learning. The trial produced data that learners analyzed in “real time” during the class. The mock RCT is a fun and engaging approach to teaching RCTs and helping students to develop skills in critical appraisal.
