In the new biology-learning curriculum for Israeli high schools, known as Biomind, students experience "open-inquiry." This paper describes a qualitative action research project that was performed in order to investigate the characteristics of the open inquiry learning process. Specifically, the research investigates this process in…

For several decades, science teachers have used bottles for classroom projects designed to teach students about biology. Bottle projects do not have to just focus on biology, however. These projects can also be used to engage students in Earth science topics. This article describes the Earth System Science Project, which was adapted and developed…

Paul F-Brandwein was a visionary who looked at education broadly. He left us with an insightful view of the ecology of education in which he identified three ecological systems: school-family-community, postsecondary, and cultural. The first part of this lecture, by Dean B. Bennett, examines Brandwein's ideas related to environmental education and…
