The study is on the use of truth table chart (TTC) in the academic achievement (AA) of logic gate (LG) in computer science among junior secondary schools (JSS) in Port Harcourt. Quasi experimental design and descriptive research survey stood espoused for the study. The population of the study remained 4380 with 110 sample size. The study had four purpose of study, two research questions and two hypothesis. The instrument for statistical assemblage remained the questionnaire and the test items titled “Logic Gate Achievement Test (LG-AT)”. The instruments were subjected to face in addition to content validity. The reliability of the instrument coefficient was 0.81 and 0.75 with the aid of Kuder-Richardson. And the split half of reliability was espoused. Mean as well as standard deviation (SD) was espoused to analyze the research questions whereas analysis of covariance (ANCOVA) for the hypotheses. The findings revealed that those groups taught using TTC achieved more than those taught without TTC. Also the results proved no significant difference in the interface influence of age in addition to sex on logic-gate learning achievement of students taught using TTC and those taught without using TTC.
