This lesson plan outlines an interactive workshop on how algorithms and algorithmic bias influence the information and choices that are presented, or not presented, to individuals in online environments. The workshop also explores the implications of algorithmic bias in our everyday lives and society and its disproportionate impact on historically marginalized groups. The workshop is founded on the understanding that technology is not neutral and that algorithmic awareness and more critical use of digital technologies are essential starting points for counteracting the negative effects of algorithmic bias and advocating for more ethical information systems.
