Antonio P. Gutierrez de Blume, Ph.D., is currently an associate professor of research at Georgia Southern University, where he teaches quantitative research methods and statistics. His research expertise is in examining metacognition under the theory of self-regulated learning. More specifically, he is interested in how learners monitor their comprehension during learning episodes. His program of research includes examining the effects of dispositional characteristics (e.g., various aspects of motivation) and learning strategy training on learners’ calibration (accuracy and bias), confidence in performance judgments, and performance as well as investigating the latent dimensions of calibration to improve its measurement.
