Query: Essays on Eclipses, Transits and Occultations as Teaching Tools in the
  Introductory Astronomy College Course   We occasionally include projects in our learner-centered introductory
astronomy college course to enable non-science major students explore some
astronomical concepts in more detail than otherwise. Such projects also
highlight ongoing or upcoming astronomical events. We hope that students will
feel more interested in astronomy through projects tied to astronomical events.
In Spring 2012, we offered short essays focused on eclipses, transits and
occultations to promote the rare transit of Venus that occurred on June 5th,
2012. We asked students to write two short essays from three that were offered.
The essays contained descriptive and conceptual parts. They were meant to serve
as teaching tools. 62% of 106 essays from 55 students earned A, B or C grades.
21% of 47 feedback survey respondents felt the essays increased their interest
in astronomy. 49% of respondents felt that the essays were not educationally
beneficial and should not be offered again. The most common written response to
our survey indicated that students need more guidance and better preparation in
writing successful essays. Since students found the conceptual parts of the
essays difficult, in the future we will provide relevant activities prior to
essay deadlines to help students create successful essays.
