Lab Content Updates! Featured Image

We are pleased to announce content enhancements to our digital science labs for the current term. Based on feedback from our instructors and students, we’ve improved our approach to creating and delivering science simulations. For the Fall 2016 term, many of our library labs have been revised.


Please review the list of labs below carefully as they may affect your courses. If you currently assign one of the revised labs, your old version of the lab will be updated as of August 15, 2016. This affects both the view of your section and within your gradebook.

If you are using a custom version of any of these labs, we recommend switching to the new, improved versions listed below. If you are unsure if you are using custom versions, please contact for assistance.

The content updates contain:

  • An increased focus on learning outcomes with learning objectives clearly identified in the description of the labs
  • An addition to the lab’s manual demonstrating real-life connection between what students will do in the lab and how the lab’s content applies outside the lab
  • A new organization for short answer assessment questions to read more like a lab report, with sections for Lab Results, Data Analysis, and Conclusions
  • Additional questions in both short answer and multiple choice assessment demonstrating critical thinking
  • Worked out solutions to mathematical short answer questions to make grading faster and easier
  • Lab and assessment revisions by a team of subject-matter experts who teach in the field

The following labs and their assessments have been reviewed and revised to ensure accuracy, ease of use, and the new features you see above.
