Students have unique ways of learning, which may greatly affect the learning process and its outcome. In the process of education, instead of classifying students according to their insufficiency, teachers should try to get to know them and determine their cognitive, sensorial and kinetic characteristics. This study on improving learning style inventory, aims to help technical industrial teachers determine students' attributes in individualized educational activities in technical drawing course at technical/industrial colleges. The study involved four stages: determining the questions for the learning style inventory, preparing the trial inventory, applying the inventory, and determining validity and reliability. Nine experts validated the instruments: four lecturers from the University of Nigeria; Nsukka, Nigeria, and Delta State University; Abraka, Nigeria, while five lecturers and experts validated the instrument in the College of Education, Assiut University; Assiut, Egypt and College of Education, Suez Channel University; Suez, Egypt. The reliability coefficient of 0.92 was determined using students that are not part of the population under study, but registered technical drawing as a common course in College of Technical Education; Beni-Suef University, and University of Nigeria. All the data obtained were analyzed using SPSS (t-test). As a result of the analysis eight factors were determined. (Contains 4 tables.)
