In this study, the effects of grouping by extraversion and introversion in POE learning applied to elementary science class on students’ achievement, the perception of learning environment and the attitude toward science instruction were investigated. Ninety-five 5th graders were assigned to the control group and the experimental groups, and taught about acid and base for 9 class hours. In the experimental groups, the homogeneous small group was composed of four introverts or four extroverts, and the heterogeneous small group was composed of two introverts and two extroverts. Two-way ANCOVA results revealed that the homogeneous group performed better than the control group in the application subtest of the achievement test. Significant difference in learning difficulty was found between the heterogeneous group and the control group. In the attitude toward science class, significant interaction effect was found between the instruction and the extraversion/introversion. Key words: POE Learning, Extraversion and Introversion, Grouping Method.   mn Hop ;7G   qL    rs ,=9 :4F  te 3u. v`d rw9 Yxy,  Ez N{9 |4}, ~ kl9 4F €# r9 Yx‚ 4ƒ „ †( ‡y a6. M rs, <=  ~ ˆI 9 ‰
