It might be dangerous to pick only a few articles for further comment, as all these articles raise interesting issues, but I will still make a few comments about some of them.
The article by Llinares and Roig has a focus on students’ problem solving, with a particular focus on word problems. Connections are made with research on mathematical modelling (e.g. the research of Danish colleague and editor of NOMAD, Morten Blomhøj), and the article gives a nice overview of research concerning problem solving and mathematical modelling. The study that is reported in the article is a survey/test where students were faced with five questions/problems. Llinares and Roig discuss the problem-solving strategies that were used to solve the three word problems in this test.
The article by Githua and Nyabwa provides insight into mathematics teaching in Kenya, and the article builds heavily on Ausubel’s theory of advance organisers. The objectives of the reported study were to investigate whether or not there were statistical significant differences in mathematics achievement between students who had been taught using advance organisers or not, and they also wanted to investigate whether gender affected achievement when advance organisers were used.
Another interesting article was the one by Ismail and Awang, which provides more insight into factors that influenced the achievement of Malaysian students in the TIMSS 1999 student assessment.
