"Impact of Computer Modeling on Learning and Teaching Systems Thinking"

11/18/2020

 
​Third-year doctoral student Ha Nguyen (pictured right) is first author with Professor Rossella Santagata of an article in the Journal of Research in Science Teaching on the implications of teacher modeling of computer use for student learning in classroom interactions.
 
The title of the article is “Impact of Computer Modeling on Learning and Teaching Systems Thinking.”
 
Nguyen is specializing in Teaching, Learning, and Educational Improvement for her doctoral work. Her research interests include design of STEM learning experiences and multimodal assessment to study collaboration and conceptual understanding. She is advised by Professor Mark Warschauer and Professor Santagata.
 
Santagata studies teacher learning and professional development, with a focus on the use of video to foster teacher professional growth, and teaching and learning in STEM, with a focus on the development of students' conceptual understanding and on video technologies as a tool to study learning interactions. Her research utilizes a variety of methodologies including design-based research, pre- and post-test comparisons, experimental and quasi-experimental studies, and research-practice partnerships.

Santagata serves as the current director of UCI's Education Center for Research on Teacher Development and Professional Practice and as the School of Education's Global Engagement liaison. She has contributed as a visiting scholar, Institute of Advanced Studies, Alma Mater Studiorum, Bologna, Italy in 2019, and a visiting professor at the Technische Universität Berlin, Germany from 2018 to 2019. ​

​Abstract
 
Researchers have found that computer modeling fosters the learning of causal mechanisms in systems, an important crosscutting concept in science that many novice learners find challenging. Despite the research that highlights the role of teacher's instructional practices in enacting computer tools, few studies have considered teachers' use of computer modeling and its implications for student learning in classroom interactions, compared to interactions without computer tools. In this study, we examine (a) the impact of computer modeling on students' understanding of causal links in decomposition and (b) classroom interactions with use of computer modeling. We employed a quasi‐experimental design with eight middle school science classes that served predominately Latinx students. The random treatment was at the class level (computer modeling; n = 60, four classes) and control (paper modeling; n = 59, four classes). Analyses incorporated student preassessment and postassessment, classroom observations, and audio‐recorded modeling instruction. Results indicate that compared to paper modeling, computer modeling enriched systems thinking, particularly students' ability to provide causally coherent statements in explaining scientific ideas and evidence. Enactment of computer modeling may be associated with a shift in classroom interactions to include more invitation for students' elaboration of causal systems. We discuss aspects of computer modeling that may foster systems thinking, with implications for the future design of tools and curricula.
