My colleagues and I just published a paper on the design and evaluation of an online learning environment titled Geothentic:

geothentic

In short, Geothentic is an online environment that provides problem-based learning modules for the teaching and learning of geography. The student side of the environment is based on the idea of scaffolding. The teacher side of the environment is based on the idea of Technological Pedagogical And Content Knowledge (or TPCK or TPACK). The paper discusses the evolution of the environment through a design-based research lens and highlights three technology-based ways to visually assess teachers’ TPACK.If you have any questions about the paper, feel free to get in touch.

The CITE journal is an open access publication and focuses on technology and teacher education.
