SummaryAn epidemiological survey of intestinal helminthiases was conducted on 766 primary school children aged 5–16 years from Ile-Ife, Nigeria. On the basis of stool examinations, the prevalence of Ascaris lumbricoides, Trichuris trichiura, hookworm and Strongyloides stercoralis was 88·5, 84·5, 33·1 and 3% respectively. Intensity of infection was measured indirectly by egg counts for each species of helminth and also by counting worms passed after chemotherapy in the case of A. lumbricoides. The influence of host age and sex on infection levels was assessed. Relationships between the intensities of A. lumbricoides, T. trichiura and hookworm in individual children were identified. After anthelmintic treatment with levamisole, the frequency distribution of A. lumbricoides per host and the relationship between parasite fecundity and worm burden were investigated.

This paper explores the relationship between family environment and behaviour of primary school children living in three family contexts. It uses data from studies including children of married heterosexual couples, cohabiting heterosexual couples and homosexual couples, and examines the extent to which these children differ with regard to scholastic achievement and aspects of social development. It shows that in the majority of cases, the most successful are children of married couples, followed by children of cohabiting couples and finally by children of homosexual couples.

Abstract.Using an example of composite tasks and the teaching techniquebehind them, the authors describe how primary school students learn to use modelling as part of their knowledge gaining process in education. The use of modelling during math classes is one of the pre-conditions for successful learning with primary school children as with the help of modelling children can better imagine what the task implies and better understand the relationship between different values, which enhances their awareness when deciding on what operation to apply, and so on.The article describes different models and submodels used by teachers for taskmodelling. It is noted that when learning how to solve composite tasks, children learn to reflect and acquire the ability to act inside their minds and analyze their thinking.Keywords: Knowledge gaining, mathematics teaching, modelling, compositetask.
