ABSTRACT: Background: This paper focuses on the computer appreciation skills of secondary school computer studies teachers in Nsukka education zone, Enugu state, Nigeria. The purpose of this study was to find out the skills needed by computer studies teachers in secondary schools in Nsukka education zone, Enugu state Nigeria. Materials and Methods: 80 copies of questionnaire were administered to computer studies teachers in eighteen secondary schools, of which sixty eight was completed and returned. Results: The study shows that the respondents are conscious of the reality that computer appreciation skills are very vital in their career. The study concluded that secondary schools computer teachers needed in-service training in computer appreciation skills for effective teaching and learning of computer studies in secondary schools in Nsukka educational zone. That the identified computer appreciation skills should be used by curriculum planners at State and federal levels to further improve the existing curriculums at secondary in the State and the nation in general.

ABSTRACT: The motivation for this research is to adopt fuzzy logic for the groupings of a categorization model which will be used to detect cassava plant infection based on a group of dependent factors observed from various parts of cassava plants. Based on review of related works surrounding cassava plant infection detection, some factors that are related with the identification were identified and validated by experienced Botanists. Trilateral membership functions were formulated using the input and output variables via fuzzification. The rule base model was put together using IF-THEN statements to combine the values of the inputs with their respective output values. The MATLAB Fuzzy.....
