The study investigated the “Effectiveness of the Demonstration, Computer Assisted Instructions and Inquiry Method used for teaching carbon hydrates in senior secondary schools biology in Ikot Ekpene Local Government Area” Two research questions and two null hypotheses were formulated to give direction to the study. The study used a quasi-experimental research using intact classes as non-randomized pretest-posttest group design. The study was conducted in Ikot Ekpene Local Government Area of Akwa Ibom State. The population of the study comprised all the six hundred and fifty-six (656) Senior Secondary Two (SS2) Biology Students in all the seven (7) Senior Secondary Schools in the Local Government Area during 2013/2014 school year as the sample for this study was two hundred and sixty-four (264) Senior Secondary Two (SS2) Biology Students representing 40.24% of the target population in six intact Biology classes of the six (6) co-educational Senior Secondary schools in Ikot Ekpene Government Area. Stratified random sampling technique was used in selecting the sampled schools. Instrument such as “Cognitive ability test, Biology Achievement and Retention Test were used for the instrumentation. Data obtained form pre-test and retention test instruments were analysis of covariance (ANCOVA), with pre-test as covariates. All the hypotheses were tested at.05 alpha. From the result of the findings, it was observed that there is no significant difference in the performances of students on the concept of carbohydrate nutrients when taught with Demonstration, Computer-Assisted Instruction and Guided-Inquiry teaching methods and there is no significant difference in student’s retention of the concept of carbohydrate nutrients when taught with Demonstration, Computer-Assisted Instruction and Guided-Inquiry teaching approaches. It was concluded that that computer Assisted instructional Approaches followed by Demonstration have better enhancing effect on both the student’s performance and retention in the concept of carbohydrate nutrients and one of the recommendations was that all teachers of biology should make effective use of computer-assisted instruction and demonstration method in teaching the concept of carbohydrate.
