A STUDY TO INTERPRET COMMON FACTORS FOUND IN LEARNING CHEMISTRY AT SENIOR SECONDARY LEVEL

In the era of science and technology, we need students who can cope with the challenging situation of the world. To accept these challenges, need of students having some inherent potential to accept these challenges is essential. Eighteen achievement tests covering different field of Chemistry was constructed. Item analysis of these tests was done. Chi-square tests of normality of distribution were applied after computing the mean and S.D. Transformation of test scores into T- scales in test no 1 where the distribution of score was abnormal. All these achievement tests had more than.85 reliability. Product moment correlation was used to get correlation matrix between eighteen tests. Factorization was stopped after five factors. Difference between obtained and guessed communalities became less than 0.10 after first reiteration. Result indicates that there are five factors responsible for learning basic concept of Chemistry.
