Punjab Agricultural University, Ludhiana, Punjab, India.https://krishikosh.egranth.ac.in/handle/1/5810184441The 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.EnglishThesis
