... chools. Collected data were analysed using mean scores and standard deviation as well as Analysis of Covariance (ANCOVA) at .01 level of significance. Formative evaluation modes with feedback and remediation, which enabled respondents, develop good study habit and positive interpersonal relationship with their instructors and peers have proved to be very effective in the assessment and improvement of students' learning outcomes. The improvements in respondents' performances were observed in both achievements in and attitude to learning Agricultural science. It could thus be concluded from this study that formative evaluation modes with feedback and remediation are effective in improving farmers' achievement in and their attitude to learning more about Agricultural science. Formative evaluation modes with feedback and remediation enabled young farmers to engage in consistent studying. It allowed the farmers to be exposed to different formative evaluation techniques such as peer assessment, projects, group assignment instead of the usually test and individual assignment that they were used to. Need for Agricultural science instructors to acquire necessary skills in the development of various formative evaluation modes/techniques needed for the assessment of the cognitive and affective domains of the young farmers was raised. Such techniques include written quiz, end-of-lesson assessment, peer assessment, individualized task, project, group assignment, attitudinal scales, and socio-metric scale among others.
