"Teaching and Learning Science through Multiple Representations: Intuitions and Executive Functions"

1/22/2021

 
Alumna Janice Hansen (Ph.D. ‘13, pictured left) is first author of an article in Life Sciences Education describing pedagogical intuitions on best practices to maximize learning.

The title of the article is “Teaching and Learning Science through Multiple Representations: Intuitions and Executive Functions.”

​Associate Professor Lindsey Richland (right), Hansen’s dissertation advisor, is co-author.
 
Hansen’s areas of expertise include human development and learning, research methods, multicultural education, and teacher preparation. Currently, she is the director of undergraduate education for the UCI School of Education, supporting undergraduate major and minor program development and overseeing and supporting course lecturers.

Hansen served as a lecturer for both the undergraduate Bachelor of Arts in Education Sciences (BAES) and the Master of Arts in Teaching/Credential (MAT) programs at UCI, and since 2002, as an undergraduate course lecturer at California State University, Long Beach. She earned her Ph.D. specialized in Learning, Cognition, and Development. ​

​Richland’s research foci include children's reasoning, higher order thinking, mathematical thinking, and executive function. She is principal investigator (PI) on an IES grant that is studying how stress responses impact math learning in children. She also is PI on a National Science Foundation grant researching UCI undergraduates’ current stressors during the COVID-19 pandemic and the impact of stressors on students’ learning, with the goal of testing strategies for supporting effective e-learning during this period. Richland is director of UCI’s Science of Learning Laboratory.
 
Abstract
 
Reasoning about visual representations in science requires the ability to control one’s attention, inhibit attention to irrelevant or incorrect information, and hold information in mind while manipulating it actively—all aspects of the limited-capacity cognitive system described as humans’ executive functions. This article describes pedagogical intuitions on best practices for how to sequence visual representations among pre-service teachers, adult undergraduates, and middle school children, with learning also tested in the middle school sample. Interestingly, at all ages, most people reported beliefs about teaching others that were different from beliefs about how they would learn. Teaching beliefs were most often that others would learn better from presenting representations one at a time, serially; while learning beliefs were that they themselves would learn best from simultaneous presentations. Students did learn best from simultaneously presented representations of mitosis and meiosis, but only when paired with self-explanation prompts to discuss the relationships between the graphics. These results provide new recommendations for helping students draw connections across visual representations, particularly mitosis and meiosis, and suggest that science educators would benefit from shifting their teaching beliefs to align with beliefs about their own learning from multiple visual representations.
