The purpose of this study was to investigate how science teachers perceived
their learning environment compared to their students in Korea. This study
involved 354 students in 9th and 10th grades and their 8 science teachers, and
investigated their perceptions of constructivist learning environment. The
perceptions of learning environment was measured by employing the instrument
of Constructivist Learning Environment Survey(CLES). The main focus of the
CLES was to evaluate to what extent the classroom was prepared for student
centered learning in six domains; personal relevance, critical voice, shared control,
student negotiation, scientific uncertainty, and attitude. This research found that
both secondary science teachers and their students evaluated their science classes
as lowest in the domain of shared control. That is, both teachers and students
seemed to view students’ sharing control of the learning environment with the
teacher as seldom found in their classrooms. In addition, both teachers and
students showed a similar pattern in the scores in the domains of the CLES, while
the scores in each domain of CLES were different from each other. It also lead to
discussions on sociocultural constraints to limit students’ sharing control in their
learning in science classrooms.
