Abstract
The purpose of the study was to determine the effect of an instructional guide developed by the researcher on the performance of students in facing and drilling operations on the lathe machine. Two purposes, two research questions and two hypotheses were formulated to guide the study. The instrument for data collection was a Practical Exercise Performance Test (PEPT) designed to test students in the major competencies to be acquired in facing and drilling operations. Quasi – Experimental group design was adopted for the study. The mean statistic was used to answer the two research questions while the t-test was used to test the hypotheses. Results showed that students who were taught with the instructional guides performed better than those taught with the conventional lesson plan. There was significant difference (P< 0.05) in the mean performance scores of students taught with the instructional guide and those taught with conventional lesson plans in facing and drilling operations on the lathe machine. The major conclusion of the study is that practical skill acquisition by beginners is enhanced by the use of an instructional guide. It is therefore recommended that the relevant authorities particularly the National Board for Technical Education should include the Practical Skills Instructional Guide as a mandatory instructional material for the teaching of skills in lathe machine operations in technical colleges in the country.
