This study compared two teaching methods, namely, Constructivist (experimental) and Lecture (control) teaching methods on students’ achievement in metalwork in technical colleges in Yobe State. The study adopted quasi-experimental research design in which intact classes were used. Two research questions were raised to guide the study, two hypotheses were formulated and tested at 0.05 level of significance. The sample for the study was 58 students. Mean was used to answer the research questions while ANCOVA was employed to test the hypotheses. The study found out that, students in experimental group achieved higher mean score than those in control group. This implies that, constructivist teaching method is better than lecture method in arc and gas welding; and also incasting process. The study therefore recommended that, Metalwork teachers should be trained in the use of constructivist teaching method. National Board for Technical Education should consider review of curriculum for National Technical Certificate in order to incorporate constructivist method as a method of teaching Metalwork.
