The approach used by teachers is very important to the success of the teaching process. This is why this study seeks to determine which teaching approaches – problem solving and subject-matter, would best improve the problem solving ability of selected secondary agricultural education students in Ikorodu Local Government Area. Ten classes and 150 students, based on Hay’s (1973) cluster sampling formula for determining sample size, were selected. The classes were taught with instructional units prepared using the problem solving approach model presented in Newcomb, McCracken and Warmbrod (1993) and subject matter approach as described by Rosenshine and Steven (1986). At the conclusion of all instruction, a problem solving ability posttest and Group Embedded Figures Test (GEFT) Instruments were administered to all participants. The scores obtained from the problem solving ability posttest was analyzed using the univariate analysis of covariance and it found, among other things, problem solving approaches scored significantly higher (P=0.046) on the posttest than scores of students assigned to classes using the subject matter approach. The implication of this figure is that the problem solving ability of secondary school students can be accelerated with instructional approaches, such as the problem solving technique.
