dents' preparation for postsecondary education. Today's urban educators are faced with challenges that Woodson could not have imagined in 1933. High levels of poverty in communities, school violence, high dropout and turnover rates, language challenges, and diminishing funding lead to the observation that teaching is one of the most difficult and least-recognized professions in the United States. That said, there are still strategies that the individual classroom teacher might adopt to...

This paper discusses the findings of a study into the potentials of peer coaching as part of a professional development program, consisting of an in-service course and exemplary curriculum materials, in supporting the implementation of learner-centred teaching in senior secondary science and mathematics education in Botswana. Teachers in the study organised several peer coaching activities and considered them beneficial. They primarily indicated having learned about general teaching issues...

The question of which language(s) to use for teaching and learning is a crucial one in bilingual and multilingual contexts. In former colonial countries, it is a question that has occupied the agendas of many governments since they attained independence. Some countries have made strides towards addressing it (e.g., Tanzania and Nigeria), although it continues to haunt others.

Two recent onshore-offshore seismic transects across the Namibian passive margin reveal a thick (to 20 km) prism of material at the base of the crust with high seismic velocity (Vp = 7.1-7.6 km/s). To better understand the nature of this material and the processes that formed it, we estimate the bulk chemical composition of the high-velocity crust by relating its seismic velocity to a petrophysical model that links basalt composition and conditions of partial melting of peridotite. Observed...

Abstract The use of children's literature in urban social studies classrooms to facilitate students' engagement in literate behaviors and simultaneously develop a framework for understanding social action is an under -researched area. This paper discusses the use of literature for children and young adults in an urban middle school language arts and social studies block as a pedagogical strategy to facilitate understandings of social action. The African American students' responses to...

During the study period of 31 months (1 November 1994-31 May 1997), the sociodemographic characteristics of 200 women attending the family planning clinic of Nnamdi Azikiwe University Teaching Hospital (NAUTH) Nnewi, South East Nigeria were studied. The peak age group of the family planning acceptors was 31-35, constituting 82 (42%) of the study population. Women of parity 5-7 constituted 99 (49.5%) of the study population; 66 (33%) women sought contraception less than 4 months after...

This paper examines the health effects due to air pollution on peasant farmers in Benue State, Nigeria. The study is based on the review of epidemiological data collected from clinics and hospitals in the State. The diseases found to be prevalent in the study area include allergic asthma, pulmonary tuberculosis, pneumonia, upper respiratory tract infection (URTI), chronic bronchitis and visual impairment. The ambient air quality in the state is far worse than national and international...

Leach's storm petrel Oceanodroma leucorhoa have bred at Dyer Island since at least 1995; a review of earlier records in the light of this discovery indicates that breeding has almost occurred since at least the 1970s. The South African offshore islands on which Leach's storm petrel almost certainly breeds are Jutten, Dassen, Dyer and St Croix. The South African population is probably of the order of 25 pairs. The migrant component of the Leach's storm petrel population visiting southern...
