Abstract
The purpose of this study is to reveal how alien species are dealt with in textbooks about living environment studies, science, and biology from elementary to high school. From an analysis of students’ responses in lessons about alien species, possibilities and points to be noted for executing science lessons about biodiversity in elementary school were also examined. As a result, the following three points were identified.
(1) The textbooks checked in this study have a total of 126 kinds of alien species, of which 10 are alien invasive species, and 23 are careful invasive species.
(2) The textbooks have some description of how to cope with the problem of invasive species for most of alien invasive species; they also and have descriptons suggesting that their multiplication and release are encouraged, wheras
there is little description about careful invasive species.
(3)There are lessons that we had suggested to the students for proper understanding of alien species, indicating that lessons that encourage understanding of alien species in elementary school are possible. We have to examine opportunities and contents for doing so.
