摘要：The purposes of this research were to study environmental knowledge and environmental ethics of undergraduate students who learned by taking instructional process based on infusion of environmental ethics, to compare environmental knowledge and environmental ethics between experimental and the control groups and to compare environmental knowledge and environmental ethics between experimental and control groups with different sexes. Sixty of fourth-year undergraduate students in environmental technology major were sampled. They were assigned into two groups. Experimental and control groups consisted of 30 students each. The findings revealed that the experimental group students and the control group students showed their environmental knowledge at 69.00 and 60.75% of total score. In addition, the first group indicated that their environmental ethics at the level 4 (goodness of environmental ethics) and the latter group at level 3 (societal ethics). The experimental group had higher score of environmental knowledge and environmental ethics than those control group (p<0.05). Female students in the experimental group had higher score of environmental knowledge and environmental ethics than those male students (p<0.05). In conclusion, environmental education teaching process using ethics infusion could develop students’ environmental knowledge and environmental ethics at a high level which were greater than the control group. Therefore, the teachers should support and incorporate the instructional strategies into environmental education curriculum.
