This study is a kind nonequivalent pretest-posttest designs of quasi-experiment in life education. The experimental group is the six grade class led by the researcher, and the control group is another six grade class of the same school. The researcher executes analysis of covariance of the grade school pupils' life attitude evaluation scale and quality data, in order to explore the meaning, value and feasibility of life education. The researcher wishes to become the reference for someone who wanted to work about the life education by executing the curriculum of life education.
