It is necessary to teach media communication itself in Korean education. Critical
comprehension education by analyzing television advertizing text is the representative example.
Criticism and critical comprehension are the same in a sense that both judge the goodness or
badness of matters. But criticism may be recognized as a negative meaning. The term \'critical
comprehension\' was used in the consideration of emotional attitude education of Korean
education.
The advertizing text was studied in the concept of intrinsic approach and extrinsic approach.
Intrinsic approach is to study advertizing genre through intrinsic elements of advertisement
such as sociocultural factors and subjective or ideological meanings. Extrinsic approach is to
study advertizing genre through extrinsic symbols of advertisement. In this study a television
advertizing text of a commodity, chlorella, in which the concept of \'health\' was expressed as
a slogan of \'in line with nature\', was analyzed. Through the analysis of the advertizing text it
was found that the advertisement reflected modern sociocultural code by inserting the slogan
of \'in line with nature\' into upright-standing \'plant and human\' which symbolized the nature,
that woman or motherhood symbolized the nature, that the green colour symbolized health,
that white colour symbolized purity and innocence, and that the advertisement used indirect
speech through image. By such analysis first meaning and second meaning of advertisement
were studied. The critical analysis of advertising text will give learners, who accept the
advertisement unconsciously and uncritically on the flood of advertisements, many-sided
educational points of Korean ability in the functional field, social field, emotional field, and
cognitive filed.
