strategies on SSI students’ in Ecology in Zone C, Benue State. Quasi experimental research

design of non-randomized pre-test, post- test was used for the study. The population

comprised of all SS 1 students in the Zone. Using purposive sampling technique, four schools

were selected and a total of 146 students participated in the study. Student Interest Inventory

(SII) was used for data collection. The reliability coefficient of SII on 50 students after trial

testing using Cronbach alpha was found to be 0.82. Mean and standard deviation were used

to answer the research questions while the hypotheses were tested at 0.05 significant level

using ANCOVA. The study found mean difference between interest ratings of students taught

with advanced organizer and those taught with guided inquiry strategy in favour of those

taught with guided inquiry. The study also revealed that gender has significant effect on

interest ratings of students in ecology using the two teaching strategies. It was recommended

that ecology should taught using guided inquiry for students to be in control of learning and to

arouse their interest of male and female students in ecology.
