Science class is the starting point of science education where science teacher and students meet together to teach and learn science. Therefore successful science class is the main concern of various educational partakers, such as teachers, students, parents, school administrators, and science education researchers. In order to find what is important among the teaching abilities of science teachers, a survey was conducted to the various educational partakers. As the result of survey, students chose ``progressing a lesson`` and ``teacher`s attitude`` are important, and in-service teachers chose ``analyzing learner characteristics and curriculum`` and ``teacher-student interaction`` are important, while the pre-service teachers and parents chose ``teacher-student interaction`` and ``progressing a lesson`` are important. In addition, the school administrators chose ``setting up teaching-learning strategy`` and science education researchers chose ``understanding curriculum and developing teaching-learning method`` is important along with ``analyzing learner characteristics and curriculum.`` In the communication on science education among different educational partakers, these result can be used as the basic information to understand the different perspectives on a science class.
