Computer-Based Checker for Technical Drafting Plates: Development and Evaluation

Abstract

The Computer-based Checker for Technical Drafting plates (CCTDp) was developed to assist the faculty and the students in senior high school to an objective, reliable and timely assessment of technical drawings under the five CAD competencies of the Department of Education. The LAN-based computer system includes features such as submission of technical drafting plates and deployment of scores and feedbacks. There are two (2) accounts developed for the checking software: the faculty and the students’ account used to access CSTDp. The scoring and feedback are based upon a TESDA TEC NC II assessors’ validated scoring criteria which cover line technique, accuracy and completeness, annotations, plotting and speed. It was also evaluated using ISO 25010 by IT practitioners, TEC NC II assessors, teachers and SHS students. Grand mean score of 4.80 interpreted as “outstanding” was achieved by the system which denotes that CSTDp is an effective and efficient computer-based system. It also implies that the developed system facilitates the immediate provision of scores and feedback to the learners while employing 21st century teaching strategies inside the classroom. The developed software also addressed the accuracy, reliability and timeliness of assessment for the performance-based assessment in technical drafting.
