<b>A Study to Compare the Effectiveness of Concept Mapping and Mind Mapping on Perception among B.Sc., N Students in Selected College at Chennai</b> Learning is the process of acquiring new understanding, knowledge, behaviours, skills, values, attitudes and preference. An experimental study was conducted to compare the effectiveness of concept mapping and mind mapping on perception among B.Sc. Nursing students at selected college. A true experimental research design was adopted for the study. The study was carried out with two groups that who fulfilled the inclusion criteria. A total of 60 samples in which 30 samples were allotted to group 1 and 30 samples were allotted to group 2 using simple random sampling technique. Modified Ingleton questionnaire was used to assess the level of perception regarding concept mapping and mind mapping. After pre test, Group I received concept mapping as a teaching strategy and Group II received mind mapping as a teaching strategy daily for one week. Post test was conducted after one week with the same tool. The analysis revealed that, in Group I, the mean level of perception had increased from 20 to 38 and standard deviation was decreased from 6 to 3. The paired t test value of 15 was very highly significant at p 0.001which indicates the effectiveness of concept mapping on level of perception among B.Sc. Nursing students. In Group II, the mean level of perception had increased from 19 to 40 and standard deviation was decreased from 7 to 4. The paired t test value of 14 was very highly significant at p 0.001 which indicates the effectiveness of mind mapping on level of perception among B.Sc. Nursing students. The Independent t test value of 2.9031 was not significant at p 0.05. It indicates that there was no significant difference between concept mapping and mind mapping on level of perception.
