The NYU CREATE Consortium for Research and Evaluation of Advanced Technologies in Education today released the final report for the IES funded 2005-2009 research grant Molecules & Minds: Optimizing Simulations for Chemistry Education. The research study, directed by Jan L. Plass (PI) and Bruce Homer, Catherine Milne, and Trace Jordan (Co-PIs) investigated design factors for effective simulations for high school chemistry education. Six simulations developed by the grant and curricular materials are available on the Molecules & Minds Web Site.

Abstract
Teaching with technology offers phenomenal advantages for teachers and students. Teachers can take advantage of the rich information about student progress available in embedded assessments when using technology-enhanced instruction. Our recent research compares two approaches to professional development. The Technology Enhanced Learning in Science (TELS) center implemented a targeted approach where teachers request the professional development support they need. These teachers generally requested help with technology in the first year, help using visualizations in the second year, and help with inquiry teaching in the third year. The Mentored and Online Development of Educational Leaders in Science (MODELS) project implemented a mentored approach where an on-site mentor coordinated school-wide planning, teachers reflected on student learning data, and teachers participated in a summer workshop to customize instruction. Analysis of results suggests that inquiry experience, collaboration with other teachers, and opportunity to customize can lead to changes in teacher practice that impact student learning. These studies also illustrate the importance of support from the school principal. They suggest directions for design of tools to support teachers for classroom management and communications with students.

Expertise reversal for iconic representations in science visualizations
Bruce D. Homer • Jan L. Plass
The influence of prior knowledge and cognitive development on the effec- tiveness of iconic representations in science visualizations was examined. Middle and high school students (N = 186) were given narrated visualizations of two chemistry topics: Kinetic Molecular Theory (Day 1) and Ideal Gas Laws (Day 2). For half of the visual- izations, iconic representations of key information were added. Results indicated a main effect of prior knowledge on learning in Day 1. In Day 2, a three-way interaction was found between prior knowledge, age group and icons: icons were effective for all middle school students and for high school students with low prior knowledge, but were not effective for high school students with high prior knowledge. These findings indicate that the expertise reversal effect can be mediated by cognitive development and other factors, not just domain specific prior knowledge. More…
Design factors for educationally effective animations and simulations
Jan L. Plass • Bruce D. Homer • Elizabeth O. Hayward
This paper reviews research on learning from dynamic visual representations and offers principles for the design of animations and simulations that assure their educational effectiveness. In addition to established principles, new and revised design principle are presented that have been derived from recent research. Our review focuses on the visual design and interaction design of these visualizations and presents existing research as well as questions for future inquiry. More…
