Marissa Lopez, Associate Director, Teacher Preparation
209. 386. 3054

My work integrates my experience as a P-12 educator, instructor in Teacher Education, and research on STEM teaching and learning. I am an advocate for citizen science and conservation of our natural resources. My love of science and math began in middle school and matured in high school. I had amazing teachers that inspired me to be the first in my family to earn a college degree from the University of California, Davis (1991) as a double major in Biological Sciences and German. While teaching, I completed an MA in Integrated Math & Science Education from Fresno Pacific University (2009). A specialist with project-based and hands-on science pedagogy, I created a cross-age science program at our San Joaquin Valley K-8 school where my 7th and 8th-grade students served as mentor teachers to younger students. After I completed my Masters, I had the honor of working with California science teachers through the Project-Based Science Institute at the Monterey Bay Aquarium. Before coming to UC Merced, I was a National Science Foundation (NSF) Graduate Research Fellow in the School of Education at University of California, Irvine (2013-2017), where I completed my doctorate in Education. My program specialization was Learning, Teaching, Cognition, and Development. 

Research Interests: P-16 STEM education, problem-solving, interactive learning, character development, persistence/grit, underrepresented students
