  1. Correlation between Authoring Questions and Understanding of Threshold Concepts in PeerWise HEA STEM Conference 2014 Gita Sedghi Department of Chemistry g.sedghi@liv.ac.uk

  2. What is PeerWise? • PeerWise is an online repository of multiple-choice questions that are created, answered, rated and discussed by students. • peerwise.cs.auckland.ac.nz

  3. Which courses is PeerWise for? Any course for which it is beneficial to students to author their own questions and to explain their understanding of a topic could benefit from using PeerWise.

  4. Benefits to students: • Designing questions • Choosing distracters • Writing explanations • Answering questions • Evaluating quality

  5. Benefits to instructors: • Early feedback • Large test banks • Large classes • Little staff involvement

  6. Implementation in Chemistry

  7. Example question The "Morning Rooster" is a coffee cocktail made via a steady state process. Coffee, milk and tequila are mixed in a machine and cocktail exits the machine at a mass flow rate of 2.4 kg/hr. The coffee input stream has a mass flow rate of 1.6 kg/hr. The specific enthalpies of the inputs and output are listed in the table: By assuming the heat losses from the machine are negligible, use the information in the table and the mass flow rate of the coffee stream and output stream to calculate the mass flow rate of the milk and the tequila. A)m·milk = 6 g/hr *B)m·milk = 0.06 kg/hr m·tequila= 74 g/hrm·tequila= 0.74 kg/hr C) m·milk= 0.6 kg/hr D)m·milk = 0.74 kg/hr m·tequila= 7.4 kg/hrm·tequila= 0.06 kg/hr

  18. Evaluation Which stage of using PeerWise helped your learning the most?

  19. Evaluation Was having credit attached to PeerWise a factor in your engagement?

  20. Summary • Using PeerWise to enhance students’ understanding of treshold concepts: • More focus on authoring: Most students thought authoring questions helped most. • Better correlation between question authoring and specific exam question mark for threshold concepts.
