Abstract—WorldWide Telescope (WWT) is a free software program, which brings scientific astronomy data, images, stories and other information together. It functions as a virtual observatory on computer. With many outstanding features, WWT comes to be potentially powerful technological tool that supports inquiry-based learning goals in astronomy education. The practice of WWT based teaching about astronomy has been implemented in an elective course at the Central China Normal University since 2011. Four essential steps in this implementation have been described in detail. Results from the teacher’s feedback and the survey which 137 students filled out after the course are presented in this paper. We expect that more teachers and students could benefit from this method when teaching and learning astronomy in the future.
