Abstract:
The purpose of this research was to propose a model of insinuating ethic knowledge in mathematics instruction at the lower secondary education level. The questionnaires concerning mathematics contents which could be insinuated with ethic knowledge, the ethic knowledge which could be insinuated in mathematics instruction and the techniques used in insinuating echic knowledge in mathematics instruction were sent to 189 mathematics teachers. The mathematics teachers opinions were used as guidelines for proposing a model of insinuating ethic knowledge in mathematics instruction at the lower secondary education level. The findings of the research were as follows: Mathematics teachers opinions concerning the consistency among mathematics contents, ethic knowledge in mathematics instruction and techniques to insinuate ethic knowledge in mathematics instruction were highly appropriate. The mathematics contents which could be insinuated ethic knowledge were: fraction, decimal, equation and inequality, ratio and percentage, area, volume and surface, Pythagorean theorem, probability, statistics and geometry. The ethic knowledge which could be insinuated in mathematics instruction were: responsibility, honesty, reasonableness, gratefulness, discipline, devotion, unity, preservation, justice, deligence and mercy. The indirect techniques used in insinuating ethic knowledge in mathematics instruction were: (1) students practice, such as giving assignment, group working and individual study. (2) teaching strategies, such as giving the examples to infer the ethic knowledge and using programmed lesson. The researcher constructed a model of insinuating ethic knowledge in mathematics instruction. The model consisted of rationale, objectives, mathematics contents, ethic knowledge, techniques to insinuate ethic knowledge and two illustrated lesson plans were also developed.
