In an editorial published in the Journal of Geoscience Education, a geography faculty member offers a testimonial in favor of learner-centered teaching. “Through my 15 years of teaching Earth System Science, I have explored various ways of teaching it and have become convinced that the Learner-Centered Environment, that builds upon constructivist theory principles and fosters teaching practices that recognize the active roles students must play in their learning, is particularly suitable for Earth system science education.” (p. 208)
