The relationship between class size and academic performance of secondary school students in geography has been a perplexing one for educators. Studies have found that the physical environment, class overcrowding, teachers' methods, grade level, pupil characteristics and subject areas and other learning interventions are the variables that affect students’ achievement (Molnar, et al., 2000). Other factors that affect student achievement are school population and class size (Gentry, 2000 Swift 2000). Since the attainment of independence in 1960, Nigeria has been experiencing unprecedented growth and expansion in secondary school education. According to Fafunwa (1982) secondary schools increased from 315 – 1240 between 1960 and 1965, the figure quadrupled in 1970 as a result of the revenue generated from the oil boom in Nigeria. In all the states of the federation, there was a corresponding increase in students’ enrolment at both primary and post-primary schools, the increase is ev...

Cases of violence and behavioural problems in primary schools in Nigeria have attracted much concern from the government, institutional functionaries and academic fellows in recent years. Despite the implementation of the many suggested solutions given by researchers, these problems are still on the increase in our primary schools. This study is an attempt to find out some of these behavioural problems and their causes. It has been suggested by parents and educational administrators that the school today is a less disciplined community than in the olden days. The impression which has been created is that the teachers today commit more offences than their counterparts did in past years. The number, variety and magnitude of school offences frequently reported in the country's news media are such that are very serious enough to cause some concern for people who are involved in the school administration. The question is whether the present deterioration in the standard of behaviour...

              Recently, the reports of poor academic achievement of students especially in secondary schools have raised more attention and greater concerns among stakeholders in Nigerian education. Academic achievement or academic performance is the outcome of education, that is the extent to which a student, teacher or institution has achieved their educational goals (Ward, Stoker, & Murray-Ward, 2000). Academic achievement is commonly measured by continuous assessment or examination but there is no general agreement on how it is best tested or which aspects are most important, whether procedural knowledge such as skills or declarative knowledge such as facts (Stumm, Hell, & Chamorro-Premuzic, 2011). Irrespective of the method of academic measurement, Isangedighi (1999) observed that indiscipline, drug addiction, poor socio-economic background of the parents, inadequate motivation on the part of students, lack of information ...

Introduction Deforestation is the removal of a forest or stands of trees where the land is thereafter converted to a non-forest use. Examples of deforestation include the conversion of forestland to farms, ranches, or urban use. Deforestation occurs for many reasons: trees are cut down to be used or sold as fuel (sometimes in the form of charcoal) or timber, while cleared land is used as pasture for livestock, plantations of commodities and settlements. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and aridity. It has adverse impacts on the biosequestration of atmospheric carbon dioxide . Subsistence farming is responsible for 48% of deforestation; commercial agriculture is responsible for 32% of deforestation; logging is responsible for 14% of deforestation and fuel wood removals make up 5% of deforestation. Other causes of contemporary deforestation may include corruption of government institutions, the inequitable di...
