The result
showed that the teachers of the Social Studies Textbook evaluated assessment of
examples and statements, and analysis and evaluation skills as not satisfactory
respectively. They evaluated the other skills as fairly satisfactory. Teachers of
Sociology Textbook 1 evaluated explicitness, assessment of examples and
statements, analysis and evaluation, and interpretation skills as not satisfactory
respectively. They also evaluated other skills as fairly satisfactory. Teachers of
Sociology Textbook 2 evaluated explicitness as not satisfactory, logicality as
satisfactory, and other skills as fairly satisfactory. Therefore it is possible to rank
order the social science textbooks of high school as satisfactory and not
satisfactory with regard to the use of critical thinking. In other words, Sociology
Textbook 2, Social Studies Textbook, and Sociology Textbook 1 were ordered on
a continuum of satisfaction from satisfactory to unsatisfactory, respectively.
