This study aims for the development how to organize a more student-centered inquiry
teaching strategy. The Lawson\'s empirical inductive learning cycle model is used to develop the
strategy to be applied in the current circumstances of Korean science classes at schools, which
separately conduct laboratory classes from ordinary science classes.
Lawson\'s cycle model has three stages; exploration, introduction of terms and application of
acquired idea. Lawson emphasizes that the exploration with students\' active participation
should be preceded before the other process when students start to learn science, in his model.
Inquiry experiments are developed in this thesis in order to encourage students to lead science
classes at school laboratories. These inquiry experiments have been made with two different
topics coming from \"Science 3\" used in Korean middle schools; The topic is \'land and sea
breeze\' from the section of \'the circulation of water and weather change\'. This inquiry
experiments is consisted of \'Introduction\', \'Observation\' and \'Explanation\', in order, with the
form of inductive I․O․E. Inaddition, sub-textbooks for students and guide books for teachers
are suggested for the experiments. Three standards to evaluate students\' performance in the
experiments are also set by the categories of \'used skills for the inquiries\', \'performance\' and
\'attitude\' to the experiments so that teachers can carry out objective and process-focused
evaluation on their students\' efforts to the classes.
The created strategy in this thesis ultimately prioritize laboratory inquiry classes according to
the Lawson\'s empirical inductive learning cycle model. That is, in the primary step, students
undergo \'exploration\' being the center of the inquiry experiments at the laboratories. Afterward,
in the secondary step, the introduction of terms, which introduce related terms and explain
them, and the application of acquired idea are carried out at ordinary classrooms. In the
process of idea application, students solve given questions and internalize acquired ideas.
Newly developed strategy for school inquiry experiments in this thesis will help Korean
science classes turn to be more student-centered, in other words, students have more leadership
in the classes than teachers do.
