Effectiveness Of Expeditionary And 5E Model Teaching Methods On Biology Students’ Academic Achievement On Plant Classification In Abak Municipality, Nigeria

The study was on plant classification using expeditionary, 5E and didactic teaching methods. Three research questions and three null hypotheses were formulated and tested at 0.05 level of significant using quasi-experimental design. The population was 3,786 and the sample size was 138 SS2 Biology students. Students were assigned into experimental and control groups using simple random technique. Researchers made test, Biology Achievement Test in plant classification (BATIPC) with a reliability coefficient of 0.86 was used after validation using Kuder- Richardson formula-20. Data generated were analyzed using descriptive analysis and ANCOVA. The findings showed that students taught plant classification using expeditionary and 5E teaching methods achieved significantly better than those taught with didactic teaching method. The findings also showed no significant difference between the mean achievementscores of male and female Biology students. It was recommended among others, that Biology teachers should make use of expeditionary and 5E teaching methods in the teaching of plant classification.
