Cost-benefit Analysis of Rating Scale and Criterion Reference Assessment Technique for Determining Students’ Performance in Rice Production in Ebonyi State, Nigeria
Journal of Agriculture and Ecology Research International,
The objectives of the study were to determine the difference in costs of ingredients, the benefit in percentage score of students’ performance and the difference between the benefit in percentage score of students’ performance determined through the two assessment modes RS and CRAT- by implicating rice production in Ebonyi State. The study adopted quasi-experimental design. The population of the study was 570 made up of 20 teachers of agricultural science and 550 students offering agricultural science for the Senior Secondary School Examination (SSCE) in Ikwo and Ivo Local Government Areas of the state. The sample of the study was 100 made up of 60 senior secondary II students and 40 teachers of agricultural science. Four sets of instruments were utilized for data collection. The reliability of the content- validated RS items was determined using Cronbach alpha formula which yielded a coefficient of 0.82.Split-half and Kudder-Richardson (K-R 20) was utilized to determine the stability of the test items which yielded a coefficient of 0.80. Procedural steps was adopted to administer and collect data from the two schools using the RS and CRAT items. Data collected was analysed using percentage, weighted mean and sign test to answer the research questions. Real limits of numbers were utilized to take decision on percentage. The study found out that the estimate cost of CRAT was cheaper than that of RS by ₦13,643.20. The study also established the benefit of CRAT (over RS) which can be utilized as a substitute to “alternative to practical” mode of determining students’ performance in rice production. It was recommended, among others, that external examination bodies should infuse the use of CRAT into their examination policy and that teachers of agricultural science should seek for training in CRAT development for use in determining students’ performance in relevant areas of agriculture.
