The Earth Science / Geology learning objects originate from the faculty-librarian collaboration between Prof. Marc Laflamme and Joanna Szurmak.
Its objective was to devise an activity and a learning object designed to teach the threshold concept of different source types in the sciences. Specifically, students were guided through an exercise in which they read, analyzed and compared a primary and a secondary source on the same topic published in the same journal.
The Planet Earth (ERS 120) learning object was created to mirror the primary / secondary source learning experience first introduced for third year students in ERS 313.
You may notice there is more scaffolding for the first year students.
