A Study to Evaluate the Effectiveness of Concept Mapping Over Conventional Lecture Method in Terms of Knowledge regarding Arterial Blood Gas (ABG) Interpretation among selected Nursing students in Central Kerala

A quasi-experimental comparative study was done to evaluate the effectiveness of concept mapping over conventional lecture method in terms of knowledge regarding arterial blood gas (ABG) interpretation among selected nursing students in central Kerala. The objective of the study were to evaluate the effectiveness of concept mapping over conventional lecture method in terms of knowledge regarding ABG interpretation and to find the association of level of knowledge regarding arterial blood gas (ABG) interpretation with selected demographic variables among nursing students. Convenience sampling method was used to select 68 nursing students from 4th Semester B.Sc nursing who were grouped into two groups; control group (34) and experimental group (34). Data collection was done using Structured Knowledge Questionnaire on ABG interpretation. Collected data were analysed by using repeated measures ANOVA, Independent ‘t’ test and Karl Pearson’s Correlation test. The study findings reveals that there is a statistically significant difference in the median score between concept mapping and conventional lecture method (p<0.05). The result also reveals that there is a statistically significant association between the knowledge and socio demographic variable, year of study (p=0.039). From the findings of the study, it is clear that concept mapping is a more effective teaching method than conventional lecture method.
