Expanding PhET Interactive Science Simulations to Grades 4-8: A Research-based Approach

点击翻译按钮获取中文摘要

The project will develop and study the impact of science simulations, referred to as sims, on middle school childrens' understanding of science and the scientific process. The project will investigate: 1) how characteristics of simulation design (e.g., interface design, visual representations, dynamic feedback, and the implicit scaffolding within the simulation) influence engagement and learning and how responses to these design features vary across grade-level and diverse populations; 2) how various models of instructional integration of a simulation affect how students interact with the simulation, what they learn, and their preparation for future learning; 3) how these interactions vary across grade-level and diverse populations; and 4) what critical instructional features, particularly in the type and level of scaffolding, are needed. Working with teachers, the team will select 25 existing sims for study. Teachers and students will be interviewed to test for usability, engagement, interpretation, and learning across content areas. The goal will be to identify successful design alternatives and to formulate generalized design guidelines. In parallel, pull-out and classroom-based studies will investigate a variety of use models and their impact on learning. Ten new simulations will then be developed to test these guidelines. Products will include the 35 sims with related support materials available for free from a website; new technologies to collect real-time data on student use of sims; and guidelines for the development of sims for this age population. The team will also publish research on how students learn from sims.
