This study aimed to determine the learning outcomes that the students in Ecology achieved at the Eco- Park at West Visayas State University Lambunao Campus, Lambunao, Iloilo. The participants of the study were the BEED IV- B students taking Bio 217 (Ecology) during the first semester of the school year 2009 -2010. The students divided themselves into four groups. Each group conducted ecology- related activities such as construction of herbal garden and nursery for fruit bearing trees, waste management, and biodiversity assessment. Performances of students were self- rated and validated by their group leaders and the subject teacher. Teacher's basis for the grades/ score included pre and post- tests, interviews, transcripts of focus- group discussions, field notes, journals of reflection, photo elicitations of workplace and activities of students, checklist, and informal visits. Learning was in the real world where students appreciated the relevance of the scientific method to the environment. The said environment was different from the controlled, school science laboratory room. Students became fascinated with nature, and they had the opportunity to explore the plants and animals in their environments. Outdoor education at an Eco- Park enhanced the students' learning of ecology.
