DEVELOPMENT AND VALIDATION OF COMPUTER AIDED TESTING MODULE FOR TECHNICAL DRAWING IN AKWA IBOM STATE, NIGERIA
Abstract
This study developed and validated Computer Aided Testing Module for Technical Drawing, (CATMTD). Adopting instrumentation design, a personal home page (php) software was written for test management and administration. Four specific purpose-based research questions were posed and three hypotheses were formulated to guide the study. A random sample of 10 teachers and 81 students of Technical Drawing was selected from public secondary schools in Akwa-Ibom State, Nigeria in 2012/13 session for furthering the work. Modular web-based CATMTD php software compilation in local host (computer) comprised 435 resourced, peer-trialed and psychometric analyzed objective test items for handy deployment and data collection from the students. Also, structured software functionality assessment questionnaire (CATMTDFAQ) was administered to the teachers under study. Content-sprpecified tests were as well administered to subjects for five consecutive weeks based on Item Response Theory of Testing IRT – Rash Model. The data collected were analyzed and interpreted using descriptive statistics: mean (ı̅) (and at 3.50 acceptance level). Also, analysis of variance, ANOVA and t-test statistic were used to test the null hypotheses at 0.05 levels of significance. Results obtained from the analyses revealed that neither school location nor gender had significant influence on technical drawing students’ learning achievement. However, technical drawing students’ learning achievement increased with increased periodic tests. Adopting this innovative testing technique, workshop/seminar retraining of teachers on test item construction and analysis, test management and administration were recommended.
