SUMMARY African governments are turning to computers in their efforts to build stronger economies and more efficient public services. Ministers of Education in Africa are facing the difficult question of whether schools should have computers and what the machines should be used for. A recent study funded by the Harold Macmillan Trust provides data from several African countries for this policy debate. This paper analyses and discusses the issues and quotes the cases of Kenya and Zimbabwe, two countries taking a lead in this field.

Special problems and challenges face the teacher of management in societies undergoing paradigm shift. It is suggested that the fundamental values and assumptions underlying the dominant paradigm of society and consequently of the students and teachers themselves become the object of investigation and debate. This is a process of introspection and not, as in the traditional mode of teaching, a matter of transferring skills from teacher to student. This is illustrated by means of two...

Soil water properties were estimated in the field, using guidelines established in Canada, for five volcanic-derived soils in Tanzania. Many of the estimates for horizons near the surface were satisfactory but those for water retained at − 1500 kPa by horizons below a depth of 1 m were far too low. These low estimates combined with underestimates of air porosity at − 10 kPa for many of the samples resulted in very poor estimates of available water capacity. The guidelines were not directly...

Eighty-four cases of illegally induced abortion presented at the University of Nigeria Teaching Hospital (1982-1986), or 4 per 1000 deliveries. Seventy-one percent of the patients were 20 years or younger and 8 out of 10 were nulliparous. Medical practitioners were responsible for one-third of the cases. Presentation and treatment are described. Fifteen women died (179 per 1000 cases). The true number of deaths from abortion in the community is probably higher.

SUMMARY Two sets of experiments were conducted on oxic Plinthustalf and udic Ustochrept soils in 1983–85 at Ouagadougou, Burkina Faso. One set tested six daylength-insensitive (DI) cultivars and the other set compared four or five daylength-sensitive (DS) cultivars with one or two DI cultivars as controls, sown on three or four dates. Sowing date, cultivar and their interaction significantly affected seed yield in 1983 and 1985. In 1984, yield was not affected by sowing date in the DI...

SUMMARY Two sets of experiments on cowpea sowing date were conducted in 1983–85 at Ouagadougou, Burkina Faso. One set tested six daylength-insensitive (DI) cultivars and the other compared four or five daylength-sensitive (DS) cultivars with one or two DI cultivars as controls. Sowing after inadequate rainfall, particularly when followed by drought stress, impeded seedling establishment and growth. Severe drought stress during the reproductive growth stages and prolonged drought stress...

A cross-sectional survey of households was carried out in a dracunculiasis endemic village in Oyo state Nigeria. Data were collected on history of dracunculiasis, occupational and domestic sources of drinking water, clinical manifestations, disability, use of folk medicine, and incorporation of previous dracunculiasis control programmes. The findings indicated that dracunculiasis patients were usually unaware of their infection 3-5 days before the appearance of a bleb; that religious...

Abstract The educational computer programming language LOGO is assumed to foster cognitive development. The cognitive effects of LOGO were examined among 8- to 9-year-old Black and White Zimbabwean schoolgirls. Forty-nine experimental group children were exposed to a British Broadcasting Company (BBC) LOGO program, and fifty-eight control group children were exposed to BBC Computer-Aided Instruction programs. Pretests on the SRA Primary Mental Abilities Test for Grades 2 to 4 (Thurstone,...

Drawing on the experiences of Kenya and Tanzania, investigates how the expansion of the educational system affects productivity and the growth and distribution of income. Explains that Kenya and Tanzania, with their similar colonial background, resources, and economic structure, but markedly divergent educational policies, constitute a natural experiment. Obtains measures of both reasoning ability and cognitive skill from surveys of representative samples of urban wage employees, allowing...

The study objective was to analyse the dynamics of the teaching-learning situation in Southern Nigeria Agricultural Schools. Data were collected from 107 Agricultural Assistants-in-training and 54 Agricultural Superintendents-in-training, in January to March. 1981 through the questionnaire. Most respondents were males with a neutral attitude towards agriculture, although. they perceived their courses as relevant to their training lecture and demonstration were the commonly experienced...

Nigeria is a multilingual society with about 250 different languages accompanied by many dialects. Such a situation makes for a comfortable adoption of the English language as the official language of government and as the language of instruction in schools. Internal politics apart, the English language affords Nigerians easy communication among the many linguistic groups in the country and with other English speaking peoples all over the world. The position the English language holds in...

A list of 53 primary schools was obtained from Ikorodu Local Government of Lagos State, Nigeria. Five primary schools were chosen from the list by numerical series which had a total of 4,515 pupils representing 13.6#pc of the total primary school population. Two hundred and fifty pupils were chosen randomly using Fisher#shYates random sample table. The following information enumerated from the study. Chi‐square value [P#lt.05] showed relationship between the PCV level and nutritional status...

In Ethiopia only one-fourth of primary school-age girls are actually enrolled. Despite progress since the 1974 revolution, 57% of all females who enter grade 1 drop out before reaching grade 2. This paper reports on regional variation in girls' persistence through primary school and performance on the national exam. We then examine the relative influence of community characteristics and school qualities in explaining female persistence and performance, based on a sample of 182 schools and...

This study involves six English Second Language Teachers working in two different Education Departments responsible for the education of Blacks in South Africa. The teachers participated in a Participatory Research process towards developing a critical discourse in materials development for classroom use. -- This thesis is divided into two parts. The first describes an exploratory process in which the participants responded to specific research questions through a procedure of general...
