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.
