Investigating teacher leadership in Cameroon secondary education : a case of two public schools

2018

Teacher leadership is crucial in improving schools and enhancing student learning. In Cameroon, the hierarchical nature of leadership and the internal school structures encourage the partition of roles and responsibilities and a clear separation of power and authority. Teachers in Cameroon work within a more imposed system, where the national curriculum is design and impose on them. As a result, teachers do not perform activities geared towards leadership. To improve on teacher leadership practices in Cameroon and learn from exemplar systems (e.g., Finland), it is important to examine how teacher leadership is practiced and how it can be improved. Accordingly, the purpose of this study is t…

Schooling pupils with disabilities in Franceand Cameroon: a comparative analysis

2016

International audience; he right to education and academic success of all are the concerns of all time regardless of the contexts (UNESCO, 2008). Unfortunately, despite the solemn affirmations and commitments to education for all and inclusive education, the question of the effectiveness of including all-out pupils with disabilities remains a relatively unexplored topic. Inclusive education implies a paradigm shift in which the conditions for success are based on the ability of the school to adapt to the diversity of the public it hosts (Plaisance, Belmont, Verillon et al., 2007; Dyson, Millward et al., 1999). Some researchers (Armstrong, 2001; Ainscow, 2003) showed that if educational poli…

Seroepidemiology of pertussis infection in an urban childhood population in Cameroon.

1991

In 1989, the prevalence of IgG antibodies to pertussis toxin (PT) in a sample of 367 unvaccinated apparently healthy children 5-14 years old was estimated by ELISA in Kumba City (Cameroon). Children were recruited using a systematic random sampling from six primary schools located in different districts of the city. The sample was representative of the various socioeconomic classes. The overall prevalence was 75%; it increased from 62% in 5 year old children to 81% in children 12-14 years old (P less than 0.01). IgG antibody prevalence was positively related to the family size. Children belonging to households of nine or more members had a 2.2-fold risk (C.I. 95 per cent = 1.1-4.6) of previ…

The Extractive Industries Transparency Initiative (EITI) in Cameroon : realities and prospects

2010

For a long time, Cameroon was a success story in the context of Africa’s development. Unfortunately, the economic crises of the eighties and early nineties led to the failure of the development strategies that had been pursued until then, resulting in a severe deterioration of the country’s economy and the living standards of the Cameroonian people (Mentan, 2003).
