摘要：This study is based on a Delphi study on environmental literacy which is related to both teachers professional development and
environmental science, technology, engineering, and mathematics (E+STEM ) literacy. In the light of the expert opinions, the goal is to
determine what teachers should do to develop their experiences and qualifications as E+STEM literate individuals. In this study, a “mixed
method” research design, in which both qualitative and quantitative methods are involved, is used to reveal the expert opinions. The
exploratory sequential design, which is one type of mixed method research, is used. In the first step of the Delphi study, qualitative data
are collected about teachers’ professional development. After analyses of data in the first step of Delphi study, the quantitative form is
developed for second step of the Delphi study. Finally, after analyses of the data in the second step, the final quantitative form (3rd step) is
prepared again. It is performed in three consecutive steps in Delphi study. The sample consists of the 45 experts who initially accepted to
participate in the study. 20 of the 45 experts participated in the first step Delphi. The number of participants in the second and third Delphi
study, respectively, is 44 and 26, respectively. It is concluded that there is a consensus about “having and updating content knowledge
about environmental issues,” “following the development of environmental technologies, and applying them in class.” There is additional
agreement about “having and developing pedagogical competencies for the development of teachers” experiences and qualifications
as E+STEM literate individuals. It is suggested that the concept of “environment” should be integrated into the framework of “STEM
pedagogical content knowledge (PCK)” for teacher’s professional development. By this means, a new educational and environmental
concept, E+STEM-PCK, would be incorporated in teacher education.
