Abstract

The study investigated the Effect of co-operative and demonstration teaching methods on students’ academic 
achievement in block laying and concreting in Technical Colleges in Rivers State. Three research questions guided 
the study while three hypotheses were formulated for the study. Quasi-experimental design, specifically, the nonrandomized control group design involving two intact classes was used. The population of the study was 90 
National Technical Certificate (NTC) II Blocklaying and concreting students of two technical colleges in Rivers 
State. Blocklaying and concreting Performance Test instrument was developed, validated and used for data 
collection. Reliability of the Blocklaying and concreting performance test was 0.75. Arithmetic mean and standard 
deviation were used to analyze data collected in respect to the research questions while ANCOVA was used to 
test the hypotheses at 0.05 level of significance. Findings of the study revealed that co-operative teaching methods 
has significant effect on student’s achievement in Blocklaying and concreting. It was recommended that States 
and Federal Ministries of education including professional bodies like Nigerian Association of Teachers of
