    Graphical Organizers as Course Road Maps: Using a geologic timescale in a history of life course
    Both major and non-major biology students lack understanding of important evolutionary events, how they are spaced in time, and how they relate back to the earth system. Graphical organizers like concept maps and timescales are popular tools that...
