The objectives of the study were:  (1) To find out different methodologies used for teaching science in different schools. (2) To analyze the effectiveness of these methodologies in the learning of science subject. (3) To find out concepts which are not clearly understood by the students by application of traditional methodologies. (4) To analyze the reasons which inhibit understanding of the concepts. (5) To evaluate the effectiveness of the methodology “Exploring the mind”. (6) To find out difference made by (a) socio-economic factor and infrastructure of the school, and (b) boys and girls from all selected schools in learning of the science subject when methodology “Exploring the Mind” is applied separately. (7) To draw the conclusion and give recommendations.

The hypotheses of the study were: (1) There is no significant difference in achievement of the students in learning scientific concepts and their application when traditional methodology and methodology “Exploring the Mind” are applied to: (a) control experimental group of all students; (b) control and experimental group of boys; (c) control and experimental group of girls; and (d) control and experimental group based on infrastructure of the school and socio-economic factor.

Sample consisted of 588 students studying in standard VIII selected randomly from seven schools out of 25 private co-educational English medium schools from Pune Municipal Corporation. After pretest, the selected three topics: metals and non-metals, pressure and microbes were taught to experimental group through “Exploring the Mind” methodology and to control group through traditional method by their teacher. Treatment was continued for two weeks with 35 minutes school period.

The investigator constructed questionnaire and achievement test.

The study was experimental. Pretest-posttest control group design was used.

The findings of the study were: (1) There is significant difference between the mean of experimental group and control group of all schools. The mean of experimental group is greater than mean of control group. (2) When methodology “Exploring the Mind” is applied to boys & girls in developed or developing schools, the level of achievement is the same for all irrespective of sex factor or infrastructure of the school.
