Effectiveness of instructor controlled interactive video (ICIV) in dissemination if farm technology

Abstract

The study was aimed at bringing out the effectiveness of Instructor Controlled Interactive Video (ICIV) in popularising agricultural technologies among the farming community. The impact of the different treatments of ICIV with different video formats was also experimented. The study was conducted among 150 vegetable growers from Nadathara grama panchayath of Thrissur district. The respondents were farm women cultivating vegetables. IPM in vegetables was chosen as the message to be disseminated. The dependent variables of the study were knowledge gain and symbolic adoption of IPM practices in vegetables. The set of 11 independent variables chosen covered the psychological and situational factors of the respondents. The distribution of. respondents based on knowledge gain and symbolic adoption showed that majority of respondents were in high category after participating in ICIV. Out of 11 independent variables studied six variables were correlated significantly with knowledge gain. Five variables showed non significant relationship. Multiple regression analysis showed that 62 per cent variation in knowledge gain was contributed by the independent variables. Correlation analysis of independent variables with symbolic adoption showed that five independent variables had a positively significant relationship

with symbolic adoption. One variable was negatively significant with symbolic adoption. Remaining five varied showed non significant relationship. Multiple regression analysis concluded that 59.2 per cent variation in symbolic adoption was brought about by related independent variables as a whole. The significant 'F' value indicated that all the treatments were effective in terms of knowledge gain and symbolic adoption. Students 't' test was carried out to compare the treatments. ICIV with 'Feature' mode of video presentation and ICIV with 'Skill demonstration' mode of video presentation were the most effective modes in maximising knowledge gain and symbolic adoption.
