This study investigated the effects of Cooperative learning and Analogy Methods on Secondary School Students achievement and interest in chemistry. The study which adopted a quasi-experimental design was conducted in four secondary schools in Okene Local Government Area of Kogi State. Out of these schools, two schools were exposed to the use of Cooperative learning (experimental 1) while the remaining two used Analogy method (experimental 2). One experiment was meant to control the other. The sample comprised 253 senior secondary school two (SSS2) chemistry students. The instruments used were chemistry achievement test (CAT) and chemistry interest scale (CIS) which were developed by the researcher and subjected to face, content and construct validation. While the reliability of the (CAT) was established using Kudder – Richardson formula 20 (K-R) 20 and 0.83 was obtained, the (CIS) reliability was calculated using Cronbach’s Alpha method and 0.84 was obtained. Mean and standard deviation were used to answer the research questions while Analysis of Covariance (ANCOVA) was used in testing the hypotheses at P<0.05. The result of the study revealed that both cooperative learning and analogy methods brought about significant shift in achievement and interest of SSS2 chemistry students. The researcher therefore recommended that chemistry teachers should employ cooperative learning and analogy methods of teaching in teaching their students for better understanding and achievement. In addition, other constructivist based teaching methods should be introduced in the pre-service teachers’ programme while the teachers in service should be upgraded through workshops and seminars on the effective use of these methods for the improvement of chemistry education and chemistry related courses in the Nigeria institution of higher learning.




Background of the study

              Science holds a great potential for mankind in terms of providing him with the means of reducing life’s burden on earth. Science plays profound roles in the life of individuals and the nation. Broadly, science can be defined as a body of knowledge, which is acquired through observation and systematic experimentation (Ezeudu, 2011). Science is an important enterprise. It is a way of using human intelligence to achieve better understanding of nature and natural phenomena. Science is a systematized co-ordinated knowledge based upon the accurate observation of facts and the relation of these to the general principles of laws. According to Aniodoh (2002), Science enables man as an individual to take rational decision, create a just society and understand the environment. It helps to improve an individual’s life expectancy and provides him means of tackling problems of existence such as disease and hunger. The author also emphasized that contributions of science could be seen in the area of our modern health, automation, genetic engineering; gene cloning, agriculture, transportation, building and construction. The positive overall impacts of science on the life of individuals and national economy explain why most countries including Nigeria are making huge investment in the field of science today.

Science is divided into two main branches viz Biological sciences and physical sciences. The biological sciences deal with living things, while the physical sciences are concerned with properties of non-living matter. Chemistry being a physical science is one of the main branches of pure science. These branches of science are being taught by science educators using scientific processes and educational principles.
