Development and Validation of Lessons in Ecology Integrating Concepts of Sustainable Development

This study aimed to develop and validate lessons on Grade 11 ecology integrating concepts of Sustainable Development. Specifically, it aimed to develop lessons on Grade 11 ecology and subject them to experts’ validation under the following criteria: a) consistency of the learning outcomes with the subject matter, b) appropriateness and relevance of integrated Sustainable Development concept, and c) congruency of objectives, activities, and evaluation. The five lessons that were developed focused on the fundamental ecological concepts such as the principles of ecosystem; biodiversity; biotic potential and environmental resistance; terrestrial and aquatic ecosystems and human ecological footprint. On the other hand, principles of Sustainable Development that were integrated into the five lessons were water conservation, biodiversity conservation; interdependency and environmental justice; ecological footprint and environmental stewardship. The developed lessons obtained an overall excellent rating from the expert jurors who evaluated them. This means that the lessons have satisfactorily met the standard and quality set forth by the Department of Education (DepEd). Meanwhile, the reliability of the rating provided by the jurors goes beyond the required standard (Gwet’s AC2 = 0.942) which indicates that the jurors are in congruence regarding the consistency, appropriateness, and acceptability of the developed instructional materials. The developed lessons can be utilized in teaching Grade 11 ecology and to foster awareness and positive attitudes toward sustainable development.
