This paper proposes a new approach to teach the STEM (Science, Technology, Engineering, and Mathematics) knowledge informally via robotic games. In this approach, a robotic playground is built to provide a hands-on programming and playing experience with robots controlled by Service-Oriented Computing (SOC) software, which is based on a new approach that uses reusable services (components) with standard interfaces and platform-independent interoperability. Services in the repository are annotated with STEM knowledge to enforce the required contents. In this way, students can learn computing and STEM in an entertaining manner.

Governance by policies is an important feature in service-oriented architecture (SOA). This paper introduces a collaboration policy generation technique to govern dynamic collaboration in SOA systems. Dynamic collaboration allows two parties not knowing each other establish their collaboration protocol at runtime. Traditional SOA allows parties to collaborate but with a known collaboration protocol before execution. In dynamic collaboration, as collaboration protocols will be negotiated and determined at runtime, policies need to be generated at runtime to manage the interaction. This paper presents the concepts, architecture, and illustrative examples that demonstrate the dynamic collaboration policy generation technique
