Dr. Héctor Luis Lacreu, a visionary geologist and educator, has been recognized with the prestigious Chris King Medal 2023 for his transformative contributions to geoscience education. Since 1996, Dr. Lacreu has championed innovative teaching methods that prioritize fieldwork experiences over traditional lab experiments.
Dr Lacreu introduced a groundbreaking approach, leveraging the local geological landscape to engage students in reconstructing its historical evolution using his unique “geological alphabet.” Throughout his distinguished career, Dr. Lacreu has enriched educational resources. Notably, through the “COPLA” project at the Universidad Nacional de San Luis, Argentina, he coordinated the creation of thematic educational posters to hang in classrooms, interactive tools, and educational kits known as “valijas geolodácticas.” These resources are available to all schools in San Luis, underscoring his dedication to hands-on learning.
His impact resonates in Argentina’s revised natural science curricula, which have prominently integrated an enriched geoscience section since 1996. His works is palpable not just in Argentina but also across Latin America and beyond, evidenced by the widespread international consultations of his publications.
Besides his academic endeavours, Dr Lacreu’s leadership in various national and international projects is commendable. Among his accolades, the “Juan José Nágera” award in 2017 stands out, recognizing his efforts in popularizing geosciences.
From pioneering the university extension project “COPLA” to establishing the first museum at the Universidad Nacional de San Luis, Dr. Lacreu’s vision has always been forward-looking. His legacy thrives in his latest venture, the “Geología Ciudadana” (Citizen Geology) blog, where he perpetuates the significance of geology’s role in society, rendering it inclusive and captivating for everyone.
In honouring Dr Lacreu with the Chris King Medal, we celebrate a luminary who has reshaped geoscience education for the better. His work, echoing through classrooms and beyond, will undoubtedly inspire generations of geoscientists.
