Abstract
The purpose of this research is to discover how Practical Reasoning Home Economics Instruction(PRHEI) applied to food and nutrition units would impact on the morality of female high school students. The research sample was drawn from the two freshman classes of \"M\" High School far Girls. located in the Pusan area. One classroom of 50 students was used as the test group and the other of 47 as the control group for the total of 97 students. Measuring the intellectual and behavioral morality scores followed the pre-post test design under which the PRHEI was administered to the test group during the period of eight weeks in a semester. Whereas the control group received the conventional lecture-oriented instruction during the same period. The effects of PRHEI on morality were measured using the system developed in 1972 by Ontario Institute for Studies in Education. and translated by Kim. Ahn-Jung in 1982. The system developed by Yang. Byung-Han in 1994 was utilized to measure the behavioral morality score. In analyzing the collected data. SPSS/WIN was used to generate means standard deviation and t-test. The research findings are as follows : First. The students who have been taught under the PRHEI score higher on the intellectual morality scale than the control group receiving the lecture-oriented instruction. Second. The test croup students do not show any notable differences from the control group students receiving the lecture-oriented approach on the behavioral morality scale; however, the former do show statistically significant differences from the latter in the sub-factor of honesty scoring higher means over the control group.
