(2017) Effect of Sequencing of topics on senior school students genetics achievement in Ilorin metropolis.Al -Hikmah Journal of Education, 4(1), 27-34)https://uilspace.unilorin.edu.ng/handle/20.500.12484/6812This study explored the effect of sequencing of topics on senior school students’ achievement in genetics in Ilorin, Nigeria. The researchers developed, validated and administered a 20-items short questions tagged Biology Achievement Test in Genetics (BATG) on 107 senior school students. The BATG was used as a pretest and post-test to measure the equivalent of the groups prior to the commencement of the treatment and students’ gains after the instruction respectively. A quasi- experimental design was adopted, and mean and standard deviation were used to answer the research questions, while t-test was used to test the formulated hypotheses. The study found that there was no significant difference in the achievement of students taught genetics using the researchers structured order and those taught with officially prescribed order. The study also found that there was no significant difference in the achievement of male and female students taught genetics using the researchers structured order. It was recommended that concept in genetic could be taught independently as learning of one concept does not affect the other; and that, both male and female students should be given equal consideration as far as genetics teaching is concerned.enSequencing of topicsSenior SchoolStudents Genetic AchievementArticle
