Student’s Perception of Teachers’ Knowledge, Attitude and Skills in the Teaching of Technical Drawing in Edo and Delta States, Nigeria

This paper focuses on students’ perception of teachers’ knowledge, attitude and skills in the teaching of technical drawing in Edo and Delta States of Nigeria. The empirical results are based on a quantitative survey of 300 students who were asked to evaluate their technical drawing teachers. The findings show that technical drawing students perceived their technical drawing teachers to have some negative attitudes because they disliked some of their students (2.18±1.17), rarely show concern when students have problems of poor understanding of some technical concepts (1.27±1.13) and always waited for students to remind them of their teaching periods (2.30±1.15). Some of the positive attitudes attributed to their teachers were; they always encourage good laboratory habits among technical drawing students (3.39±0.93) and encouraged parents to equip their children with the required materials they need for effective learning of technical drawing (3.34±0.91). Further, students perceived their teachers effective in preparing and organizing lesson notes adequately (3.27±0.93) as such applied facts and principles to problem-solving (3.31±0.86). The findings support the conclusion that there are aspects of teachers’ knowledge, attitude and skills in teaching technical drawing that is less than excellent and in need of further enhancement.

Competencies Required by Technical Drawing Teachers in Technical Colleges

The study was motivated by a great concern about the future and continuity of Technical Drawing in all tiers of society and our education system particularly in technical colleges. The concern stemmed from poor performance, low and declining skill practice in performance and in NABTEB Examination. Pertinent questions and doubts were raised on the required competencies of Technical Drawing Teachers currently teaching Technical Drawing in technical colleges. The study is therefore on competencies required by Technical Drawing Teachers in Technical colleges using Bauchi and Gombe States of Nigeria as a frame of reference. Three objectives were stated, research questions asked, and hypotheses formulated and tested at 0.05 level of significance. A questionnaire consisting of 54 items was structured and administered to 47 Technical Drawing Teachers in Bauchi and Gombe states. Data collected were analyzed using the Mean and t-test statistics. The study has implication for retraining, in-service training for Technical Drawing teachers and therefore recommendations involving continuous training of teachers on regular basis through workshops, seminars were made towards the implementation of the finding of the study.

Development of an Inventory of Learning Tasks for Technical Drawing instruction in the West African Sub-Region

The study was undertaken to delineate parameters for the teaching of Technical Drawing in secondary schools in the West African Sub-Region. The development of the task inventory involved instructional content analysis of the current syllabus on Technical Drawing prescribed by the West African Examinations Council (WAEC). A total number of 155 learning tasks were generated, verified, administered and sequenced according to the decreasing magnitude of their mean ratings. The sequencing shows that the tasks higher on the listing have greater instructional significance than those below them. Respondents included 110 selected Technical Drawing teachers in Lagos State secondary schools. The subjects rated each listed task on a 3-point Likert Scale, according to the instructional importance attached to each task. 50 top tasks were reported. It was suggested that teachers should on their own determine the instructional sequence of the tasks or be assisted to so. The card catalogue approach to task sequencing was recommended.
