To address this need, we introduce a novel, tool-supported framework for the development of adaptive servicebased systems called QoSMOS (QoS Management and Optimization of Service-based systems). QoSMOS can be used to develop service-based systems

Specifically, at Waves 2 and 3, standard deviations for academic performance and achievement beliefs did not differ significantly in seventh-grade classrooms from those obtained in fifth-and sixth-grade classrooms.
