ItemEditor's Overview(Georgia Institute of Technology, 2021-02) Gazi, Yakut ; Baker, Nelson C.Institutions that have been in the forefront of not only online but also of at-scale and affordable learning have been leaders of a “vertical” scale, where a limited number of programs and courses were built that sustain a vertical growth of enrollments. Responding to the COVID-19 global health crisis on our campuses entailed wide collaboration and coordination of not only technological capabilities but also human talent distributed across our institutions, to be able to quickly pivot to a “horizontal” scale of many students distributed over many courses, taught by many faculty. This book is an international compilation of institutional responses to this “horizontal scaling” of remote and online delivery of courses. Each chapter gives the context of activities at each institution/organization, followed by the strategy or operational tactics of the coordinated emergency response, highlighting successes, sharing lessons learned, charting future ambitions. The goal of this book is to distill strategies for responding to the need to quickly pivot and meet the needs of a horizontal scaling of learning as a result of emergencies.

ItemLearning at-Scale, Affordability, and Access in a Post-COVID19 World(Georgia Institute of Technology, 2021-02) Gazi, Yakut ; Baker, Nelson C. ; Sibley, KarenThe essays in this volume and many other stories from the 2020 global pandemic illustrate the challenges of urgent horizontal scale in technology mediated instruction. Many say this experience will serve to accelerate instructional change long underway and perhaps to put the ultimate spotlight on issues of equity, access and cost. As they look toward the post-COVID future our authors coalesce around the compelling necessity to develop a stable and dependable ecosystem of learning technologies enabling the talent resources and expertise to guide and support faculty, create meaningful learner engagement, and pursue new opportunities for effective, accessible, affordable higher education.

ItemDemonstration of CLIPS as an Intelligent Front-End for POST(Georgia Institute of Technology, 1999-01) Budianto, Irene Arianti ; Olds, John R. ; Baker, Nelson C.Most of the analysis codes used in the design of aerospace systems are complex, requiring some expertise to set up and execute. Usually the Program to Optimize Simulated Trajectories (POST) fails to converge when its control variables are given a bad set of initial guesses, causing the trajectory to remain in the infeasible design region throughout the computations. The user then analyzes the output produced and relies on a set of heuristics, typically gained from experience with the program, to determine the appropriate modification to the problem setup that will guide POST in finding a feasible region and eventually converge to a solution. The potential benefits of employing knowledge-based system within a design environment have long been well known. Various methods of utilization have been identified. As a postprocessing guide, an expert system can distill information obtained from an analysis code, such as POST, into knowledge. The system then can emulate the human analyst's decision-making capability based on this collected knowledge. This paper describes the implementation of POST expertise in a knowledge-based system called CLIPS and demonstrates the feasibility of utilizing this integrated system as a design tool.
