A Christian Response to Economic Inequalit
Effect of the Sequencing of Instruction on Students’ Perceptions of Engagement and Learning
Get PDFInquiry-based learning has become a hallmark of science education, in part through the introduction of the Next Generation Science Standards. Research has shown inquiry and direct instruction are effective and essential components of student learning; however, effective implementation of these strategies requires intentional sequencing and understanding of student cognition and motivation. This action research project sought to investigate the relationship between the sequence of inquiry and direct instruction and students’ perceptions of their learning through inquiry. The results of this study indicate that inquiry activities are effective for student learning and interest in the content; however, further research is needed to more fully understand the nuances of the issues involved
Sharc: Simulator for Hardware Architecture and Real-time Control
Get PDFTight coupling between computation, communication, and control pervades the design and application of cyber-physical systems (CPSs). Due to the complexity of these systems, advanced design procedures that account for these tight interconnections are paramount to ensure the safe and reliable operation of control algorithms under computational constraints. This paper presents the Simulator for Hardware Architecture and Real-time Control (Sharc) to assist in the co-design of control algorithms and the computational hardware on which they are run. Sharc simulates the execution of a user-specified control algorithm on a given processor microarchitecture configuration, evaluating how computational constraints affect the dynamical properties of the closed-loop system. We illustrate the power of Sharc by examples of MPC applied to adaptive cruise control and the stabilization of an inverted pendulum. Sharc can be found at github.com/pwintz/sharc
