Abstract
The study entitled ‘Effectiveness of extension methods for disseminating knowledge on
household waste management’ was conducted to study the existing knowledge of respondents
regarding household waste management, to develop an intervention based upon the existing
knowledge of the respondents, to deliver the developed intervention through selected
extension methods and to compare the effectiveness of selected extension methods in terms of
gain in knowledge. Data was collected from 30 respondents each from five randomly selected
urban localities of Ludhiana district. In total 150 respondents were selected for the study. Data
was collected using a pre-tested structured interview schedule. A knowledge test on
household waste management was developed and pre tested for its reliability and validity with
the score of 0.80 and 0.89 respectively. The findings revealed that two-fifth of the
respondents knew about different types of household waste. Most of the respondents had
knowledge about 3R strategy and decluttering, nearly half of the respondents had knowledge
about composting, one-third of the respondents had knowledge about household waste
disposal, and less than one-fifth of the respondents had knowledge about facts and rules
related to household waste management. All the selected extension methods were effective in
disseminating knowledge to the respondents on household waste management although
personal contact + print material showed highest gain in knowledge followed by video
conferencing + ICT based messages, video conferencing alone, and personal contact method
alone. Thus, it is concluded that face to face extension contact individually or in group was
more effective in changing the knowledge of the respondents than online extension method.
Although without any supplementary material, video conferencing method was more effective
than personal contact method alone. It was further reported that the gain in knowledge
through personal contact + print material was statistically similar to video conferencing + ICT
based messages. Whereas, gain in knowledge through personal contact and video
conferencing alone was statistically similar. Thus, it is suggested that personal contact or
video conferencing method should always be supplemented with educational materials for
more effectiveness.
