Using the ERDG Horseshoe Crab Research Data Base as a resource for teaching students how to read a scientific paper

2015.  Kreamer, Sharon W. and Yiying Sheng.  The Tatnall School, Wilmington, DE, USA. 8 pp.

This activity provides a way for high school or college-level science instructors to engage their students in exploring examples of the vast array of scientific research papers uploaded to ERDG’s Horseshoe Crab Research Data Base (www.horseshoecrab.org/research/).  Handouts guide students in learning how to read and “mine” a scientific paper, and in sharing what they have learned with their classmates. The products of these efforts can take the form of a jigsaw activity, where each student chooses a paper of interest from the HSC Research Data Base, reads through the paper following the guidelines provided, answers the guiding questions, and prepares a presentation based on the information gleaned from the article. Students share their knowledge seminar-style via PowerPoint or Prezi presentations or in poster format. An example of a student product from piloting use of this lesson is also included.
