This study was designed to find out if students taught food and nutrition concepts using the lecture method and practical work would perform significantly better than their counterparts taught with the lecture and teacher demonstrations and the lecture method only. The sample comprised 114 Jamaican 10th-graders (56 boys, 58 girls) selected from four coeducational high schools. A Food and Nutrition Test (consisting of 40 objective test items) was the instrument used to assess the students' performance. The results indicated that (a) the experimental group significantly outperformed the two comparison groups in the posttest; (b) students with high cognitive abilities in food and nutrition in the experimental group significantly outscored their counterparts with average and low cognitive abilities in the experimental group as well as their peers with high, average and low cognitive abilities in the comparison groups; and (c) there were no gender and socioeconomic background differences in their posttest performance.
