The Principle of Double Effect to Moral Education Lessons

Purpose: This paper aims to apply the principle of double effect (PDE) to morality and teaching by rethinking the principle as a moral reconceptualization that enables students' moral growth and moral practice by reconciling consequentialist and deontological ethics in the tradition of universal ethics. Methods: First, the principle of double bottom line was analyzed to recognize the need for it to be addressed in school lessons and to summarize its educational value. Next, we used a jigsaw model to implement the principle of double bottom line. Step-by-step instructions, teaching and learning guides, examples of assessment criteria, and examples of materials were presented to help teachers envision how the principle of double bottom line could be applied in their classrooms. Finally, the significance and deficiencies of the lessons were presented to show how the educational value of the theory is being realized in the lessons, reflective evaluation of the measures, and the need and direction of further research. Results: This paper presents the principle of double effect (PDE) as a reflection of the consequentialist aspect of ethics, which defines the purpose of morality as serving the human good, while at the same time respecting the consideration of deontological constraints expressed in the moral law, and reconstructs it as a concept for educational application, noting the educational value that characterizes it as an integrated universal ethics. Conclusion: A moral science course based on the principle of double consequences will contribute to the moral growth of students on a foundation of universal ethics.
