Tablet-based education and traditional classes showed similar effectiveness in teaching Rheumatic Heart Disease (RHD) to Brazilian students. Both methods resulted in initial knowledge gains but poor long-term retention, highlighting the need for further research into effective RHD prevention strategies.

Area of Science:

  • Public Health
  • Medical Education
  • Pediatrics

Background:

  • Rheumatic Heart Disease (RHD) remains a significant public health concern in Brazil, particularly due to low population awareness hindering prevention efforts.
  • Effective educational strategies are crucial for improving knowledge and potentially reducing the burden of RHD.

Purpose of the Study:

  • To compare the effectiveness of tablet-based worked examples versus conventional expository teaching for RHD education in Brazilian schools.
  • To evaluate the immediate and long-term knowledge retention of students exposed to different RHD educational methods.

Main Methods:

  • A prospective, cluster randomized trial involving 1,301 students in six low-income Brazilian public schools over eight months.
  • Classes were randomized to either expository teaching or tablet-based worked examples, with pre-tests and post-tests at 10 days and three months to assess knowledge acquisition and retention.

Main Results:

  • Baseline knowledge of RHD was low across all participants. Both educational methods yielded similar, modest improvements in immediate post-tests (approx. 71% increase).
  • Knowledge retention was poor, with a significant decline (over 20%) observed three months post-intervention in both groups.
  • High school students and girls demonstrated higher overall knowledge scores compared to younger students and boys, respectively.

Conclusions:

  • Tablet-based worked examples offer no significant advantage over traditional expository classes for RHD education in schools regarding knowledge acquisition and retention.
  • Current educational interventions provide limited long-term impact on RHD knowledge, suggesting a need for novel approaches.
  • Further research is essential to determine if improved knowledge translates to behavioral changes necessary for reducing RHD prevalence.
