The study was carried out to determined the Effects of Demonstration and problem-solving methods on performance of secondary school students in Economics in Kaduna State, Nigeria. As a guide to the study, five research objectives were formulated, five null hypotheses were raised and were tested at 0.05 level of significance. The population of the study was 121 the research design of this study was quasi-experimental designed. There were two experimental groups and one control group. The instrument used for the data collection was the Economics Achievement Test (EAT). Data collected for the study were statistically analysed using descriptive statistics, t-test and ANOVA. The objectives of the study amongst others seek to determine the effect on the mean academic performance of students taught economics using demonstration and those taught using lecture method. One of the research questions amongst others in what's the effect on the mean academic performance of students taught economics using demonstration and those taught using lecture method? The research null hypothesis among others states that there is no significant effect on the mean academic performance of students taught economics using demonstration and those taught using lecture method. The findings showed among others that there was a significant mean different of 18.47 between the mean performance of students taught economics using demonstration method and those taught using lecture method. This indicated that demonstration method students performed better than the lecture method group. The study also revealed that there was a significant mean difference of 20.39 between the performance of students using problem solving and the lecture method group. On the basis of these findings some recommendations were made include teachers of economics should use more of demonstration and problem solving methods as it enhances the performance among SS II students. Problem - solving and demonstration methods of teaching should be used for both sexes, since there is no significant effect in their performances.
