中学・高校の理科教科書の記述様式に関する予備的考察 : 従来研究の概観と課題

This paper reviews the research on Japanese science textbooks. We first give an overview of work dealing with Japanese science textbooks used in junior-high and high schools from the viewpoint of textbook distribution and usage, function and content. We then focus on research dealing with the form of textbooks: their physical attributes, layout and representative elements. We found that (1) most of the physical attributes of textbooks are positively evaluated; (2) the layout of textbooks is criticized in that some constitutional elements, e.g.,the main text and marginal information, are not clearly related to each other; and (3) some linguistic and non-linguistic representative elements are criticized for not corresponding to the developmental stage of target readers or for lacking scientic accuracy. There is no previous research, however, that deals with the descriptive patterns of textbooks, despite the importance of this aspect when studying the form of textbooks
