    Abstract

    The results of our research have shown that Slovenian middle school students have a weak understanding of mitosis and genetics. They have a solid knowledge of the basic cell structure which they have learned at school, but the meaning of cells within living organisms is poorly understood. Most of them don’t know that all living beings are made of cells. Moreover, they don’t know that division of cells takes place in all of them and that this is how gametes are created as well. They do know, however, that living beings inherit certain characteristics. They have heard of expressions such as genes, DNA and chromosomes through various media, but they can’t tell the difference between them or understand the mechanisms through which they function. Genes are frequently equated with characteristics. Students are unaware of the fact that each body cell carries complete hereditary information. The method of classifying images of mitosis phases which we have summarised from the Biology Inquiries (Schields, 2006) proved to be a successful way of learning about mitosis, as the knowledge on this subject matter, along with all chosen fields of genetics, improved significantly after our lesson. Four weeks after the lesson was carried out, a test showed a slight decrease of knowledge but the results were still very good. We have thus proven that the knowledge gained by the students through the method of classifying images of mitosis phases was longer lasting, as it was based on understanding.
