Online Class of Descriptive Geometry Including Hand Drawing

Abstract

　Until FY 2019, the classes of descriptive geometry based on hand drawing taught by the author were conducted face-to-face: real models were used to explain the basic concept of projections, the drawing process was demonstrated on the blackboard, and hand-drawing assignments were directly submitted to the lecturer. In FY 2020, the class moved online due to COVID-19. Still pictures and video shots were utilized as online teaching materials to explain the concept of projections and to demonstrate the drawing process. Scanned hand-drawing assignments were uploaded by students and comment sheets for correction and feedback were provided by the lecturer electronically. In FY 2021, the online class was conducted in much the same way as FY 2020. In both years, the term-end report, which corresponds to the conventional term-end exam, was conducted online.
