In recent years, a number of National Research Council reports have emphasized the need to improve science education and enhance science literacy for all students. In addition, the newly released "A Framework for K-12 Science Education" advocates engaging students in scientific practices and disciplinary core ideas. Children are not learning science content in a meaningful way. There is an emphasis on learning facts with little application and connection to children's lives. Teaching strategies are lacking student-to-student and student-to-teacher interactions. In order to promote science literacy and encourage a deep conceptual understanding of science topics, science teachers must actively involve children in their own learning, encourage problem-solving, promote discussion and group activities, and help children experience science in interesting ways. One method of improving the learning of science is through case study teaching. Implementing environmental science case studies helps students experience science in a meaningful way. This article describes a case study that involves the effects of the invasive plant kudzu.
