Determinants of Mathematics Student’s Academic Achievement in Junior Secondary Schools in Ogba/Egbema/Ndoni Local Government Area, Rivers State
The study examined determinants of mathematics student’s academic achievement in Junior Secondary School in Ogba/Egbema/Ndoni Local Government Area, Rivers State. A descriptive survey design guided the study. The population of the study was 3332 which comprised 3212 junior secondary school students and 120 junior secondary school mathematics teachers in Ogba/Egbema/Ndoni Local Government Area. Multiple stage sampling method was used to select 368 junior secondary school students and 48 junior secondary school mathematics teachers. Three research questions were answered. The instrument of the study was a survey questionnaire that was partitioned into three sections, structured in the pattern of Likert 5-point rating scale of agreement. The reliability coefficient of the rating scale was 0.78. Mean and Standard Deviation were used to answer the research questions, while z-test statistical tool was used to test the hypotheses at 0.05 level of significance. The study found that constant reading, good student/teacher relationship, student interest in mathematics, on the job training, self-evaluation of teachers, feedback to parents on students’ performance, provision of relevant mathematics material, regular visit of parents’ student schools and exposure of students to mathematics ambassadors. Therefore, it was recommended that mathematics students should be encouraged to have role models in mathematics and to build good relationship with their mathematics teachers to enable them have the liberty to learn more even after school hour.
Application of Group Theory to Musical Notes
This paper critically analysis the behavior and the relationship that exist between musical notes and group theory. The musical notes form additive abelian group modulo 12. Finally, the work came up with some propositions due to the musical notes behavior and their proofs one of which was name Dido’s Theorem.
Estimation of Achievement Probabilities in Corruption Dependent Achievement Probability Models
This paper proposes, develops and presents an achievement probability model in a population where achievement of some set objective is often dependent and affected by the level of corruption or corrupt practices in the population. It is assumed that in such a population there are three operatives or agencies that form a closed corruption nexus. Methods are provided for the estimation of achievement probabilities of all possible events obtainable in the proposed achievement model in the presence of corrupt practices. Test statistics are also provided for use in testing any desired hypotheses about various achievement probabilities. Some sample data are used to illustrate the proposed method. The results suggest that in some instances some gratification and negotiations between operatives in a corrupt population may be necessary for one to expect high achievement probability in set objective.
