COVID-19: The Disproportionate Impact on Underserved K-12 Students

Abstract

The purpose of this content analysis was to show the impact COVID-19 had on K-12 instructional method delivery, technology, learning, and academic achievement. The following questions guided the content analysis: How did COVID-19 impact student and academic achievement, how did the pandemic impact education and instruction method delivery in a virtual learning environment, and how did the pandemic affect teacher & student access to technology? The population consisted of K-12 educational leaders and students who completed surveys in previous studies. The findings via content analysis revealed that online education seems to be deeply rooted in the careful planning of instruction. We found that leaders were having a difficult time making the necessary adjustments with remote learning. Thus, the impact of COVID-19 has changed the way many students come to class. There is a need for K-12 institutions to strengthen their best practices relating to online curriculum and instruction demonstrated during in-person learning. Key Words: Student learning K-12, academic & instructional effectiveness, technology effectiveness, COVID-19, underserved communities

Reduction of Sonic Boom Loudness Level in Supersonic Aircraft by Optimization of Wing Geometry and Positioning

“…A supersonic aircraft forms a Mach cone, defined by the Mach angle µ = sin −1 1 M from the Mach wave [6], as the aircraft nose traveling at supersonic speeds leaves behind a spherical wavefront in a conical pattern [16]. and distorts in shape due to atmospheric gradients [5].…”
