The study examined the significant of performances of students thought using computer instructional package andLecture method. The sample consisted of 120 senior secondary school students drawn from four secondary schools. Stratified random sampling was used toselec...
ABSTRACT. In this paper, we present and analyze a choleraepidemiological model with control measures incorporated. Thismodel is extended from the one proposed in [16] by includingthe effects of vaccination, therapeutic treatment, and water san-itation. Equilibrium analysis is conducted in the case with con-stant controls for both epidemic and endemic dynamics. Opti-mal control theory is applied to seek cost-effective solution ofmultiple time-dependent intervention strategies against chol...
ABSTRACTIn this paper, a non–linear mathematical model is proposed to study the effects of irresponsible infected immigrants on the spread of HIV/AIDS in a heterogeneous population with a constant recruitment of susceptible receptors. Theequilibrium points, stability analysis, and numerical solution on the model are presented. The Routh–Hurwitz stability condition was employed to examine the stability of the disease– free equilibrium and Next Gene...
AbstractThis paper determined the effect of the convergent and divergent thinking-based instructional strategies in influencing students’ achievement in mathematics. The influence of gender on the achievement of students in mathematics was also ascertained. Two hypotheses were formulated to guide the study. a quasi-experimental pre-test, post-test, non-equivalent control group design involving two experimental groups and one control group was adopted for the study. t...
