COMPARATIVE EFFECTIVENESS OF THE PROJECTED AND NON-PROJECTED TEACHING AIDS AT THE SECONDARY LEVEL
Abstract
The Problem under investigation was “comparative effectiveness of the projected and non-projected teaching aids at the secondary level”. The study is important because it tells us clearly about the academic achievement of the students taught through projected teaching aids and through non-projected teaching aids, and if the projected aids proved useful then these can be implemented in the D.I.Khan district. The null hypothesis that “There is no significant difference in the mean post-test score of the students who were taught through projected and through non-projected teaching aids” was tested. All the secondary school students of the high & higher secondary schools were included in the study. One school i.e. University wensam College was randomly selected. A sample of 100 students was selected from this School. Two tests i.e. A teacher made pre-test to divide the students into two equal groups on the achievement and a teacher made post-test to check and compare the achievement of control and experimental group after the experiment were used as instrument of the study. The standard deviation of group A on pre-test and post-test were 0.922 and 0.682 respectively while the t-value at 0.05 level of significance is 5.741.The standard deviation of group B on pre-test and post test were 1.165 and 1.066 respectively while the t-value at 0.05 level of significance was 0.520. The results show that projected teaching aids are more effective than the non-project teaching aids in the subject of physics at secondary school level
