Magnetic iron oxide nanoparticles were synthesized and stabilized using ammonium cations or poly(vinyl alcohol) to produce amazing materials such as safer aqueous ferrofluids, ferrogels, ferromagnetic inks, plastics, and nanopowders illustrating how versatile materials can be produced just by simple modifications. The synthesis is fast, reliable,…

In this article, we present two concrete applications of the concept of the human element to chemistry education; starting with a course and experimental project on blue pigment synthesis and concluding with cross-disciplinary lessons and experiments on blue photography. In addition to the description of the content of these courses, we explore…

Field experiments are at the core of ecology, yet rarely find their way into education, probably due to a combination of technical challenges and risks associated with fieldwork. This may compromise student education and perception of the subject, making interesting, readily manageable experiments extremely important. We describe how the daily…

IN THIS SPECIAL EDUCATION ISSUE, JOHN SNYDER IDENTIFIES THE NEED FOR RADICAL REVISIONS IN THE TEACHING OF GEOLOGY AND DISCUSSES (1) RESEARCH ON TEACHING OF GEOLOGY, (2) CURRICULUM RESEARCH, (3) INCREASED EXPENDITURES, AND (4) EDUCATION OF THE PUBLIC. T. NEVILLE GEORGE COMPARES UNIVERSITY GEOLOGY PROGRAMS IN FRANCE, ENGLAND, AMERICA, GERMANY, AND…
