摘要

Scientific literacy is a fundamental skill that must have to confront demands life in 21st century. Based the analysis, scientific literacy skills and understanding of students who have taken Natural Resource Management class still low. One topic do not learned in depth is management invasive alien species, using the example invasion Acacia nilotica in Baluran National Park. Invasive alien species problems that occur in contextually suitable manner learned by problem based learning models. The purpose of this research and development is to produce effective teaching instrumentsto improve scientific literacy and cognitive learning outcomes. Teaching instruments applied with one group pretest posttest experimental design. The results of the study can be seen the effectiveness teaching instruments for 5 indicators of scientific literacy as measured by the gain score shows the average values 0.54 and the effectiveness teaching instruments to improve cognitive learning outcomes from the 5 indicators shows the average value 0.52. The conclusions of this study are teaching instruments effective to improve students scientific literacy and cognitive learning outcomes in medium category.
