Summary
All environmental problems that occur Semarang need to be raised in learning at school so that students are expected to better understand the real conditions that exist in their environment. The contextual aspect is needed in learning the environment, that environmental issues are closely related to daily life which does not merely involve knowledge but requires attitudes and skills to resolve these problems. Learning should be designed and implemented through strategies to meet these contextual needs, one of them is by learning to use socio-scientific issues (Socioscientific issues learning) (Subiantoro et al, 2013). Socio-scientific issues are issues that describe the social problems of society that are related to a conceptual, procedural, or technological context to science (Sadler & Ziedler, 2004)
