Online Workshop for Teachers: How to teach Replacement, Reduction, and Refinement (3Rs) of Animal Use in Science

March 9th, 2022, 17:00 – 19:00

Biomedical science is progressing rapidly, thanks to new approach methods and animal studies. In this course we train teachers how to educate on the 3Rs Principle of replacement, reduction and refinement of animal experimentation. The 3Rs Principle is not only about finding alternatives to using animals in research, but also about animal welfare, ethical and societal considerations, as well as responsible science for the future. 

What will the workshop offer? : The workshop will take you through the 3Rs Principle and its application. Educational material on replacement, reduction and refinement will be presented, together with a practical demonstration of a “Three Rs lesson” to illustrate how the material can be used. Exploring the 3Rs subject offers an opportunity to encourage your students' critical thinking and enhance the understanding of the challenges and opportunities in science. The workshop will also provide sources for teaching material and other teaching support.

All the resources featured are freely available and are prepared by European Schoolnet in collaboration with the European Commission's Joint Research Centre (JRC), under a European Parliament Preparatory Action entitled “Promoting alternatives to animal testing”.

Who is it aimed for? : The session is aimed at secondary/middle-school teachers, however, all educators interested in introducing the Three Rs topic to their students are invited to join. We also welcome other stakeholders that are curious to learn more about how to teach a lay audience on Three Rs.

When: March 9 from 17:00 to 19:00
