The study was carried out on the evaluation of the effects of over-population on teaching and learning of among students in junior secondary schools in Potiskum Local Government Area. To guide the study, 3 research questions in line with purpose of the study were formulated. Descriptive Survey Research Design was adopted for the study. The target population of the study was the entire teachers in randomly selected four junior secondary schools in Potiskum Local Government Area. Stratified Random Sampling Technique was adopted to select 40 teachers from the 4 junior secondary schools to constitute the sample size of the study. Structure Questionnaire was the major instrument used to collect data for the study. The data collected was analyzed using Mean and Standard Deviation for the questionnaires. The findings of the study revealed that, inability of teachers to paid attention to individual students that need special attention, lack of classroom control and management at overcrowded classroom and teachers found it difficult in conducting effective continuous assessment in classroom are some of the problems faced by teachers and students in teaching and learning in over-populated classrooms in junior secondary schools of Potiskum Local Government Area. The findings of the study also revealed that, high numbers of the students in classroom affect academic performance and that smaller class’s size lead to improvement of academic performance are some of the effects of over-population on the quality of teaching and learning in junior secondary schools in the study area. The findings of the study further revealed that, Admission of the students in junior secondary schools should be based on minimum standard as specified National Junior Secondary School Curriculum and provision of modern teaching aids such as overhead projectors, power point presentation device that each and every individual student will view the content of the lesson in the classroom are some of the ways forwards for overcoming the problems faced by teachers and students in over-populated classroom during teaching and learning in junior secondary schools in the study area. It was recommended that, a ratio of 1:40 teachers to students is hereby suggested for junior secondary schools as stated in the National Policy of Education (2013).

Soil-transmitted helminths (STHs) are one of the world’s most important causes of physical and intellectual growth retardation. The study was conducted to determine the prevalence and transmission of soil-transmitted helminths among farmers living along the metropolitan section of river Kaduna, Nigeria. Two billion people are infected globally and four billion at risk of infection to STH. Nigeria ranking first globally, accounts for about 156 million cases of STH. A total of 210 stool samples were randomly collected from farmers of seven (7) different farms located along the riverbank. The stool samples collected were examined for STHs using direct wet mount and formal ether sedimentation techniques. Questionnaires were administered to the farmers to assess their hygiene, sanitation, and health maintenance. The prevalence of STH based on the farmers' age and gender was also determined. Out of the total stool samples collected, 81(38.6%) were infected with at least one out of the four STH eggs. The eggs of hookworm and Ascaris lumbricoides were the only helminths eggs detected. Hookworm was found to have a prevalence of 54.3% while A. lumbricoides have a prevalence of 45.7%. Strongyloides stercoralis and Trichuris tichuira both were found to have 0% prevalence. The risk factors such as personal hygiene, sanitation and health maintenance were found to have a significant influence on the prevalence (38.6%) (P<0.05) of STH among the farmers. The age prevalence shows that group 10 – 25 have the highest prevalence of 81.3% while age 36 – 45 shows the lowest prevalence of 2.4%. The gender prevalence shows that male farmers have the highest prevalence of 41.4% out of the total infected farmers (81). The findings could be as a result of farmers’ hygiene, sanitation and health maintenance on their various farms and their use of contaminated farm tools which acts as a medium for the transmission of the parasite eggs, while the younger age group work more hours than the older age group and the male farmer spends more time in the farm than the female.
