摘要：Analysis of regional diferences and group differeces (gender, language of instruction) based on International Project ROSE was carried out. Conclusions based on coefficient Cohen’s d and T-test for Independet samples justify remarkable diferences between the eastern part of Latvia called Latgale and the capital city Riga. It can be concluded that interest in natural sciences and its various themes in this field depend on the person, either a male or a female, firstly, and the language of instruction in school, secondly. At the same time the language’ factor matters not exactly as the language itself, but it is dependent on the traditions in up-bringing in the family which form sound attitude to natural sciences and technology in general. Students with Russian as language of instruction are much more eager to explore themes in the field of natural sciences. The obtained results in Latvia are similar to the results in other countries. The shortage of regional data in other countries is an obstacle to carry out the reginal comparison on an international scale.
