The debate on how students of different abilities should be organised and taught is probably as old as the introduction of formal schooling. It has generated a lot of debate in the past and continues to do so in the present millennium. This debate has invariably divided the world of educational research into two distinct camps. On one hand are proponents of ability grouping who claim that this grouping approach creates homogeneity which make it possible to tailor teaching to individual needs and thus raise achievement. On the other hand, are the exponents of mixed-ability grouping, who argue that ability grouping denies equality of educational opportunities to many young people, limiting their life chances and increasing social segregation. However, there is an emerging trend which posits that teachers should view students' mixed-abilities as an asset, which if properly exploited can result in effective instruction for the benefit of all students regardless of their many individual differences. This emanates from the realisation that there are different types of intelligences, and that it is not always possible for an individual student to posses all the types of intelligences. Therefore, students from diverse backgrounds, endowed with multiple intelligences, can help one another understand the content better as they will perceive the content from their diverse experiential backgrounds. This qualitative study concerned itself with investigating how mixed-ability grouping can be optimised for effective instruction at the junior secondary school level in Botswana. The study made use of literature study, focus groups, follow-up interviews and lesson observations. Major findings were that teachers are not optimising mixed-ability grouping for effective instruction. Instead, teachers have problems in teaching mixed-ability classes, with most of their teaching being teacher-centred. However, teachers can optimise mixed-ability grouping through the use of student-centred instructional strategies such as cooperative learning, small-group instruction, peer teaching and student research. Gifted students could be catered for through curriculum compaction, enrichment and extension work, while mentally challenged students could be offered remedial work. These cited teaching strategies are differential and they make use of the diverse abilities found in mixed-ability classes. / Educational Studies / D.Ed. (Didactics)

This thesis describes the background and findings of a study of effective schools and learners achievement in Botswana senior secondary schools from an education management perspective. The aim was to identify schools that promote learners’ achievement when the students’ initial intakes were considered. The study was guided by five research questions. The study adopted an ex post facto design and a quantitative value added methodology to answer the research questions. Simple random sampling was used to select a sample of 5662 from the population of 58 032 students who wrote the BGCSE examinations for 2005, 2006 and 2007. Two sets of data: prior and later achievements at individual student level were collected from BEC and Secondary Education. The statistical software, MLwiN 2.10 beta 4, which is based on hierarchical linear modelling or multilevel modelling, was used to analyse the data for the value added by schools. The findings indicated that a) schools differ in their effectiveness. Some schools were more effective than others; b) Ten characteristics of effective schools were identified from the literature review c) schools differed in their consistency across the three core curriculum areas of Setswana, English and Mathematics; d) schools differed in their stability from year to year and e) schools were differentially effective. They were effective for the mid ability students and boys more than the other groups. The study confirmed that the use of a single statistic measure even in value added analysis could be misleading because of the internal variations between departments in schools. Furthermore, the uses of raw results for measuring school effectiveness were misleading. Some schools which were at the top in raw results were not doing so well in terms of value added and vice versa. The value added measures of school performance proved to be the most appropriate measure of school’s contribution to students’ learning. The value added by schools is also a measure of schools’ productivity. The study made recommendations to improve practice, such as the use of appropriate and fairer methods to evaluate and compare schools. The areas that need further attention were suggested based on the findings of the study. / Teacher Education / D.Ed. (Education Management)
