The purpose of this study was to investigate the effects of the constructivist instructional model on the acquisition of atmospheric pressure conceptions and learning motivation. The step of constructivist instruction was prediction and explanation-experiment and observation-discussion-application. The control group consisted of two classes of students who participated in the teacher-centered instruction. The experimental group consisted of two classes of students who participated in the constructivist instruction. To examine students' preconceptions before the instructions, a preconceptions test was administered. After the instructions, students' acquisition of atmospheric pressure conceptions and learning motivation were measured with a researcher-made post-conceptions test and The Course Interest Survey. The results from this study were as follows: First, the constructivist instruction is more effective method in acquisition of atmospheric pressure conceptions and learning motivation than the teacher-centered instruction. Therefore, in order to increase the acquisition of science conceptions and to decrease the science misconceptions, we need to use the constructivist instructional model which make learners self check their own preconceptions of science. Second, the constructivist instruction is more effective than teacher-centered instruction in three elements of learning motivation. So, we need to develop the effective ARCS(attention, relevance, confidence, satisfaction) strategies in order to use the constructivist instructional model and to verify it's effectiveness. Third, to improve teaching and learning methods, educational researchers should carry out studies using many points of view than studies biased constructivism or objectivism. In this respect, we need to contrive how to integrate constructive view points and objective view points.
