Harmful algal blooms (HABs), or red tides, have increased in frequency and severity due to climate change, significantly impacting mariculture. Phycotoxins produced by certain microalgae accumulate in bivalve molluscs, posing health risks to humans. Education is vital for raising awareness and fostering communication networks to assist managers in addressing this issue. Problem-Based Learning (PBL) is an active methodology that enhances understanding among students and the public, training future researchers and environmental managers to tackle challenges like HABs. This study engaged two public education classes in the Lake Region of Rio de Janeiro, Brazil, in a PBL course focused on harmful algae. Results indicate that PBL promotes meaningful learning on this topic. When paired with concept maps, PBL yielded specific insights and reflections on tutorials and related activities. Thus, PBL can effectively develop scientific foundations, create reflective learning environments, and empower citizen action among involved social actors.
