The purpose of the present study is to figure out the characteristics and differences among eight textbooks of high school ScienceⅠB (Earth Science) which are currently used in high school, by comparing and analysing the contents of them.
The conclusions are as follows :
1. The contents of each unit are not much different among textbooks since they are written according to the curriculum ordinance and textbook guidelines of the Ministry of Education. However, the contents and the sizes of the newly introduced unit 1 on "Exploration of the Earth" are found to vary significantly from one to another. This unit is also found to be rather formally and inattentatively written.
2. In many instances certain identical concepts and phenomena are found to be described with different terminology in different textbooks.
3. some physical quantities are found to be described in different ways for the identical concepts and phenomena in different textbooks.
4. The amount of figures and tables are similar to each other, but two textbooks contain significantly smaller amounts.
5. Similar amounts of experiments observations and investigations are included among different textbooks, but less than half of such contents are included in two textbooks.
6. The amount of pages devoted to each field is found to be ordered as follows : Geology, astronomy, Meteorology, Geophysics, Oceanography, etc., However, the relative amount vary significantly among different textbooks A and D. This is believed to be caused by preponderance of authors in certain fields instead of balanced composition.
Therefore, the education authorities are urged to unify the terminology and physical quantities that are used differently for identical concepts and phenomena by consulting with textbook writers and professional institutions so that efficient teaching and learning can be achieved in the school.
In addition, considering the multi-science nature of Earth Science which emphasizes the interdisciplinary approach as well as the importance of Earth Science as a basic science, the textbook should be written without preponderating of certain field over others.
