气候变化和生物多样性危机迫切需要重新审视教育的关键作用，以提高学生对环境现实的认识。必须总结经验教训，将生态概念与现实生活情况和当前的环境问题联系起来，并纳入人类价值观。本研究开发了六个教训的背景下，在菲律宾的设置，重点是生态系统和生物多样性的一年级大学生。这是为了提高学生的概念理解，解决问题的技能;和意识，欣赏和承诺保护环境和生物多样性。在研究的第一阶段，专家使用一套标准对课程进行了验证，并在课程目标、活动和评价的一致性、教学策略/方法的创新性和可理解性方面将课程评为“非常好”。第二阶段是研究者在生物科学课堂上尝试运用不同的创新教学策略/方法进行价值整合。前测和后测的结果显示，学生的平均学习成绩有了显著的提高。在每节课中使用学生日志，以进一步证实课程有效性的统计解释，特别是第三个因变量，使用量规和简单的频率计数将其评为“优秀”。生物科学的六节课已被证明是有效的，可以作为教师的指导和整合到科学和相关学科的课程大纲。关键词：气候变化，生物多样性，情境化的经验教训，菲律宾设置
Climate change and biodiversity crisis are compelling imperatives to revisit the crucial role of education to highten awareness among students to the realities in the environment. Developing lessons that link ecological concepts to real-life situations and to current environmental issues/problems with the integration of human values would be indispensable. The present study developed six lessons contextualized in the Philippine setting with focus on the ecosystem and biodiversity for first year college students. This is aimed to enhance students’ conceptual understanding, problem-solving skills; and awareness, appreciation and commitment to conservation of the environment and biodiversity. In the first phase of the study, the lessons were validated by experts using a set of rubric, and rated “Very Good” as to the lessons’ consistency of objectives, activities and evaluation, innovativeness of teaching strategies/approaches, and understandability. The second phase was the lesson tryout by the researcher to biological science class using different innovative teaching strategies/approaches with values integration. The pre-test and post-test results showed a significant mean gain which means an improvement in the students’ learning. The students’ journals were employed in every lesson to further substantiate the statistical interpretation of the lessons’ effectiveness specifically on the third dependent variable which was rated “Excellent” using a rubric and simple frequency count. The six lessons for biological science have been shown effective which can be adopted as guide for teachers and integrated in the course syllabus in science and allied subjects.
