The purpose of this study was to investigate Korean Language, English, and Mathematics
teachers' perceptions with respect to the selection of government-authorized textbooks for Korean
secondary schools. To be more specific, this study identifies the process of selecting textbooks and
analyzes teachers‘ perceptions on evaluation areas and standards for selecting textbooks. The
study also compares the perceptions of Korean Language, English, and Mathematics teachers on
the selection criteria. A survey was conducted and 278 secondary teachers responded to the
questionnaires. To analyze the data, descriptive frequencies, cross-tabulation analysis, MANOVA,
and paired t-tests were used. The results of this study were as follows: first, secondary teachers,
regardless of their subject area, mostly used the general standards developed and distributed by
Ministry of Education, Science, and Technology when they were selecting a textbook for their
school. Second, the degrees and orders of perceived value and applied value of the teachers on
the general textbook selection criteria appeared different. Overall, they perceived 'Content
Selection (4.02)’ as the most important area of the textbook selection criteria, and 'Assessment
(3.98)' as the second most important area. They considered, however, 'Content Selection (3.65)'
and Content Organization (3.65)' the most important sub-standards, followed by 'Assessment
(3.83)', when they were actually selecting their textbooks. In addition, 'motivating', 'appropriate
levels of content', and 'appropriate amount of materials' were perceived, in that order, as
important sub-standards. Third, the results of the above perceptions varied according to teacher
subject area: Korean Language, English, and Mathematics.
