Understanding the nature of science (NOS) has been a major component of scientific literacy
and an important learning goal in science education (American Association for the
Advancement of Science, 1993; Millar & Osborne, 1998; National Research Council, 1996, 2000).
To achieve this goal, it is necessary to include appropriate views of the nature of science in
science curriculum including a textbook. The aim of this study was to conduct a qualitative
content analysis of the first chapter of four Korean high school life science I textbooks, which
typically discusses what life science is and how it works. Examination using a qualitative
analysis reveals that most of life science I textbooks limited to include a variety of views of the
nature of science in the introductory chapters while some textbooks have included more aspects
of the nature of science than others. Specifically, high school life science I textbooks have
focused on the content knowledge itself relating with living organisms rather than the nature
of scientific knowledge such as tentativeness and diversity of knowledge in the chapters. Also,
although the textbooks have introduced a variety of scientific episodes in history as well as
scientists, generally they emphasized the historical development of science in society not the
nature of scientific thinking and attitude of scientists. Significantly, most of life science I
textbooks emphasized on the STS (Science, Technology, and Society) aspects of the nature of
science and focused on the steps of “the scientific method” to explain the inquiry process. This
is deficient to show an authentic view of the nature of science.
