Pliocene–Pleistocene Bed I of Olduvai Gorge, Tanzania provides an ideal test for models of element mobility during closed-basin saline–alkaline tephra alteration. Samples of a single phonolitic lapilli-rich layer of marker Tuff IF were collected across a transect of paleo-lake Olduvai, including authigenic K-feldspar and phillipsite bearing samples from the central saline–alkaline lake basin, less altered phillipsite and chabazite-bearing samples from the intermittently dry lacustrine and...

This study examines whether participating in competitive policy debate influences high school completion, academic achievement, and college readiness for African American male students. The analysis examines data from the Chicago Debate League from 1997 to 2006. Debate participants were 70% more likely to graduate and three times less likely to drop out as those who did not participate, even after accounting for 8th grade test scores and grade point average. Debate participants were more...

Abstract The government of Botswana is committed to recognising, supporting and strengthening the different languages and cultural traditions of the country by the year 2016, within the education system. The main way in which this goal will be attained, is by implementing the curricula that were reformed in 1998. The curriculum emphasises the need for learners to understand their cultural practices, to develop self-esteem, pride and appreciation for the national cultural heritage, and to...

Abstract This article explores language practice in Botswana in the context of disseminating information related to environmental issues. Despite the fact that indigenous languages are invaluable carriers of environmental education, the current language policy in Botswana does not provide room for the use of the different indigenous languages-messages conveying information on environmental matters are still presented either in English or Setswana. To situate that argument, the article...

With the enactment of the Civil Unions Bill in 2006, South Africa became the fifth country in the world, and the first in Africa, to legalize same-sex marriage. While supporters of the bill hailed the decision as signaling the end of discrimination against homosexual couples, critics slammed it as undermining traditional marriage between a man and woman. The attitudes and beliefs of a sample of South African students regarding homosexuality and same-sex marriage were investigated. A survey...

Abstract Two fundamental pedagogical principles that underpin the National Curriculum Statement (NCS) in the General Education and Training band (Grades 7–9) are, firstly, a high level of knowledge and skills for all; and secondly, the progression and integration of knowledge. The purpose of this study was to investigate how teachers of three grade 9 classrooms in three diverse schools have responded to these principles. The study was framed by Bernstein's sociological analysis of the...

Integrated clinical clerkships represent a relatively new and innovative approach to medical education that uses continuity as an organizing principle, thus increasing patient-centeredness and learner-centeredness. Medical schools are offering longitudinal integrated clinical clerkships in increasing numbers. This report collates the experiences of medical schools that use longitudinal integrated clerkships for medical student education in order to establish a clearer characterization of...

Gamaliel) taught a similarly modified version of an existing course at their own institution. Professor Dakas, a former Hauser...

Thesis [M.Ed.] -- Wichita State University, College of Education, Dept. of Curriculum and Instruction

The main purpose of this study was to critically examine the conceptions students in the integrated science major and non-integrated science major have about integrated science. Participants were 187 student-teachers enrolled in a University of Education in South-West Nigeria. They all did integrated science at the Junior Secondary School (JSS) level and offered physics, chemistry and biology at the 100 and 200 levels in the University. Finding of this study revealed that, contrary to...

This paper, based on the findings of a qualitative study, discusses the influence of Ghana's recently introduced English-only language-in-education policy on pupils' classroom communicative practices and learning generally. It highlights how the use of English – an unfamiliar language – creates anxiety among students and stalls effective classroom participation. The paper first considers the key issues that impinge on the literacy development in multilingual classrooms in postcolonial Africa...

While blood lead levels (BLLs) in many western countries have progressively declined since 1976, in Nigeria high BLL continue to be documented not only in exposed workers but also in "unexposed" control subjects. The problem of environmental lead exposure has hitherto gone unaddressed by both researchers and health policy makers in Nigeria despite the immense public health importance. Continued high BLLs in Nigeria cast doubt on researchers' ability to find real "unexposed control subjects"...
