The objective of this research were : 1) Develop a teaching learning model based on affective domain development to promote health care of women students in levels secondary school in 3 aspects which were : learning achieve, value development and performance concerning health. 2) Find the effective of the model development. Related theories, principles, approaches, researches including need and problem in learning and teaching were studied, analyzed and synthesized into a prepared model which received a critical review form groups of experts in various fields experimenting with two experimental group in Chulalongkorn University Demonstration Secondary School and Buddhajakvittaya School. The results of this research were 1) The developed model consisted of 8 teaching-learning steps : 1.1) pretesting students’ values, 1.2) investigating health problem situation, 1.3) collecting date, 1.4) expressing feelings and thinking, 1.5) analyzing data, 1.6) practicing selected values, 1.7) organizing value system, and 1.8) following-up 2) It was found from model experimentation that 2.1) Post-test mean women of both experimental groups in 3 aspects (learning achievement, value development and performance concerning health) were significantly health that the pre-test mean scores at the .05 level. 2.2) Post-test mean scores of both experimental groups in all 3 aspects were significantly higher than those of the control groups at the .05 level.
