Through the study, the investigator tried to analyze the effectiveness of e – Content in Mathematics on Mathematical Thinking among Secondary School Students. the research works showed that it was possible to promote Mathematical Thinking in children by means of suitable techniques in teaching Mathematics by providing suitable teaching experiences. Hence, through the study, the investigator tried to find the effectiveness of e – Content in Mathematics on Mathematical Thinking among Secondary School Students. the investigators adopted Experimental Method in the present study on a sample of 112 Secondary School Students taken at random. The study revealed that the e – Content in Mathematics is effective over Activity Oriented Method on developing Mathematical Thinking of Students at Secondary level.
