This study is related to development of students' ability of self-expression and communication. In education of English, we need to raise students' "basic knowledge of English", "knowledge of practical usage", "knowledge of life and culture of Japan and other countries", "interest and motivation for English and culture of other countries". We should also make students consider understanding of others. We introduce our practical study of "Chit-chat Card Activity" and "English Portfolio". "Chit-chat Card Activity" enhances students' "basic knowledge of English" and makes students consider understanding of others. "English Portfolio" develops students' "basic knowledge of English", "knowledge of practical usage", and "knowledge of life and culture of Japan and other countries".
