About us

Background and a Brief History

The development and distribution of the iStarClass system are guided by Dr. Lei Bao from the Ohio State University.  

Dr. Bao is a Physics Professor at The Ohio State University (OSU), and the director of the OSU Center for China-US Education Research and Exchange (CUEE).  He is a member of the advisory committee on international gateways at OSU, and has served multiple terms as the Chair of the international education committee of the American Association of Physics Teachers (AAPT).

Dr. Bao obtained his Ph.D. in Physics at the University of Maryland in 1999, and joined the faculty at the Ohio State University in 2000. He has been conducting research in a wide range of areas in science education. His research fields include: education assessment, cognitive models of learning, behavioral studies of student learning process, alternative conceptions and conceptual change, scientific reasoning and critical thinking, science inquiry for problem solving, and education technology. These research projects are supported by the National Science Foundation (NSF), National Institute of Health (NIH), and The Department of Education. 

Stemmed out his research in science education, Dr. Bao has been developing technologies and inquiry-based pedagogy to transform the traditional classrooms and improve student learning. The first clicker project started in 2000, which used the first-generation infrared remote clickers as both a formative assessment platform and a collaborative learning (and peer instruction) tool. Through research, a new clicker method was developed which uses finely crafted question sequences to support scaffolded inquiries in collaborative learning settings. Extensive research has shown that using the new methods, comparing to traditional lectures, often improve student conceptual understanding by 10-15%.

To support the research, Dr. Bao also developed the world first and only two-way infrared remote clickers, which have been widely used in the introductory physics courses at OSU. Since 2010, the technology development has shifted to using web and mobile devices in classroom polling. Our first web clicker system was piloted in 2011 and has been implemented in some of the physics classes since 2012. After several years of testing and improvement, the iStarClass system is now ready to support our extended education community and benefit students world wide.
