Integrated and subject-specific : an empirical exploration of science education in Swedish compulsory school

This thesis is an explorative experimental study in two parts of different ways of organising Science education in the Swedish context. The first study deals with the question if students attain higher scores on test results if they have been working with integrated Science compared to subject-specific Science i.e. Biology, Chemistry and Physics. The second study concerns the similarities and differences between integrated Science education and Science education in Biology, Chemistry and Physics, especially in the teaching organisation. The introduction describes the nature of integrated curriculum, what integrated learning is, issues about integrated Science education, in what way integration is carried out, between subjects or within subjects, what the opposite to integrated Science is (here named as subjectspecific science education) in the Swedish context and what the Swedish curriculum has to say about integrated Science. Previous studies in integrated curriculum looking at students’ results are referred to, and it is argued for the use of the OECD’s PISA assessment instrument in this study. The thesis consists of two studies, one quantitative and one qualitative, within the above framework. The quantitative study is an attempt to find differences in scores on students’ written results on a large-scale assessment in scientific literacy between students studying in different organisations of Science education. The qualitative study is an attempt to describe differences at classroom level between integrated Science and subject-specific Science. This gives a quite rich description of four schools (cases) in a small town and how they organise their teaching integrated or subject-specific. No differences in students’ results between different Science organisations were found in the quantitative study in this thesis. Possible explanations for the lack of differences in students’ results are discussed in the article. An additional investigation that attempts to test the variable used in the quantitative study is carried out in the thesis, with an attempt to sharpen the teacher organisation variable. This is done to find out if it is possible that there can be found differences with the sharpened variable. The qualitative study gives a glimpse of some differences in the implemented curriculum between schools working with integrated Science education and a school that works subjectspecifically. The teachers do the overall lesson plans in different ways according to which organisation according to integrated or subject-specific Science they work with. When asked in a survey what kind of Science organisation they have, students from the four schools studied answered differently between schools and also, sometimes, within the same school. A further analysis of this second study is carried out by defining a conceptual framework used as structure and a possible explanation for differences between students’ views and teachers’ views on the organisation of Science education. This latter analysis tries to give an enriched description in mainly the two levels of the implemented and attained curricula, and tries to discuss the difference in students’ attained curriculum. A final discussion concludes the thesis and concerns an elaboration of the results of the thesis, problems with the main variable involved in the two studies and the possibility that the teacher actions effects also the magnitude of students’ achievement on tests
