The potential of information technology (IT) in education modeization has been widely acknowledged.Among the broad efforts for advancing education IT,digital education resources continue to receive a high level of attention,with the goal of making high-quality education resources pervasively accessible anytime and anywhere.Unfortunately,the amount of such high-quality resources is still limited,particularly those suitable for mathematics education [1].General expectations for high-quality digital mathematics education resources (MERs) include interactivity,openness,and transparency,all of which benefit enhancing the sustainability of MERs [2].In this case,openness of an MER refers to the resource being easily edited and extended;transparency means that users have convenient access to the original development process of the resource.With these features,MERs can be continuously improved and augmented according to users individual needs.The development and utilization of such MEPs often rely on the deployment of a specialized "software or platform",which is commonly referred to as the "operating environment (OE)".
