Abstract
To assess the expertise of rubber growers, a knowledge test was created. The majority of the 37 questions were created by endorsing reasonable thinking above root memorization and to distinguish between competent rubber growers who are less competent. The results of the sample respondents' scores were subjected to item analysis, which included calculating the item difficulty index and the item discrimination index. The scale used for the final selection has 17 items with difficulty indices between 36.66 and 60 and discrimination indices between 0.58 and 0.73. The reliability of the knowledge test under development was examined using the Split-Half method, and it was found to be 0.722.
Aims: To construct a knowledge test to assess rubber growers’ knowledge on Rubber Plantation Development and Extension Scheme.
Study Design: Descriptive study.
Place and Duration of Study: Karimganj, Assam, between January 2021 and December 2022.
Methodology: A no. of items were collected and 37 items were kept. The majority of the 37 questions were created by endorsing reasonable thinking above root memorization and to distinguish between competent rubber growers who are less competent. 37 questions were pretested to 30 random rubber growers.
Results The results of the sample respondents' scores were subjected to item analysis, which included calculating the item difficulty index and the item discrimination index.
Conclusion: The scale used for the final selection has 17 items with difficulty indices between 36.66 and 60 and discrimination indices between 0.58 and 0.73. The reliability of the knowledge test under development was examined using the Split-Half method, and it was found to be 0.722.
Keywords: Knowledge test, rubber growers, difficulty index, discrimination index, reliability
