This study was conducted to find out the effect of using systems instructional approach (Dick & Carey) model in developing psychomotor skills among students of building trade in technical colleges in Imo State. The poor performance of building trade students in practical work (psychomotor skill) in the National technical Certificate Examination (NTC) conducted by National Business and Technical Education Board (NABTEB) in recent times prompted this research work. The study is an attempt to find solution to the poor academic performance of students of building trade in their practical paper II of the National Technical Certificate Examinations being conducted by NABTEB, while also helping to improve the teachers’ ability on how to deliver their lessons successfully using step-by-step (using skills check-list) embedded in the systems instructional approach. The researcher viewed with utmost concern the over dependency by technical teachers on the predominant lecture (chalk & talk) method of instruction which is only suitable for large audience, note-taking, and for cognitive and affective development. The researcher reviewed indepth, scholarly literature pertaining to the study to sharpen the focus of this research work under the following sub-headings: conceptual framework, theoretical framework, theoretical studies, review of related empirical studies and summary of review of related literature. The researcher adopted the systems instructional approach and designed his instruction prior to the commencement of the study. The design employed was the quasi-experimental research, non-equivalent control group design to ascertain the effectiveness of the systems instructional approach model, using 150 National Technical Certificate II students of the four technical colleges in Imo State. The instrument for data collection was the Psychomotor Skills Achievement Test in Building Trade (PSATBT) developed by the researcher. Three research questions were analyzed using the mean comparative method, while analysis of Covariance (ANCOVA) and paired samples t-test statistic were used to test the four hypotheses at 0.05 level of significance. Results of the study among others showed that there was significant difference between the academic achievement of the experimental and control groups in the post-test (PSATBT) as revealed by their mean scores in favour of the experimental group. This was attributed to the treatment (systems instructional approach model) given to the experimental group. Based on this, some recommendations were made for effective application of the systems instructional approach model for psychomotor skills’ development by technical teachers. This particularly will serve as a standard for guiding teachers in designing instructional activities that have to do with psychomotor skills impartation. It will also safeguard technical teachers against setting unrealizable or immeasurable instructional objectives, improper use of instructional techniques and biased assessment of students’ work piece, thereby resulting in poor academic achievement of the students. The researcher further recognized that with the rapid growing unemployment among graduates, competent psychomotor skills development would enhance employment creation through self-employment and out-sourcing skilled labour. Lastly some suggestions were made for further studies in other technical areas.
