Bill Brooks is a postdoctoral scholar in the School of Chemical, Biological, and Environmental Engineering at Oregon State University. His Ph.D used written explanations to concept questions to investigate technology mediated active learning in the undergraduate chemical engineering classroom. He current interests involve using technology to enhance educational practices in promoting conceptual understanding. He is the primary programmer of the AIChE Concept Warehouse and his current focus is on its continued development, specifically creating and integrating Interactive Virtual Labs.

Development of an Android-based Student Mobile Application for the AIChE Concept WarehouseIncorporating user feedback to continually improve educational innovations is imperative for theadoption and sustained use of those innovations. We report on the development, initialdeployment, and usability evaluation for a user-suggested improvement to the AIChE ConceptWarehouse: incorporation of an Android operating system based Student Mobile Application.Our intent is to share what we have learned through our improvement process, such that otherinnovators can benefit from the lessons learned through our experience.The AIChE Concept Warehouse was developed with the goal of fostering a community oflearning within chemical engineering. The Concept Warehouse’s cyber-enabled databaseinfrastructure is designed to promote concept-based instruction through the use of conceptquestions in core curriculum courses like Material/Energy Balances, Thermodynamics, TransportPhenomena, Kinetics and Reactor Design, and Materials Science. Concept questions, both asConcept Inventories and as ConcepTests, are available to help lower the barrier of using concept-based instruction and assessment. This instruction and these assessments can be used to promoteand evaluate student learning in real-time. The instructor can then adjust the pace of lecture inresponse to student understanding, spending more time on more difficult concepts. This tool alsoallows for reflective assessments such as the “muddiest point.”A Student Mobile Application has been developed to make it easier for students to submitanswers and written explanations to these assessments using mobile devices. Previously, studentscould input their answers to conceptual questions using clickers, smartphones, and laptops.However, input via smartphones was cumbersome because it depended on a student’s webbrowser and the full size web page. The improved student interface will facilitate studentparticipation by making it easier for them to submit responses via smartphone.Once the application was developed, we conducted initial usability testing with students who hadbeen using the previous web-based options for answer submissions. In order to assess theusability, usage statistics from pre- and post- application release and student responses tousability surveys were collected. Survey responses were used to identify student likes anddislikes and compare the different available options for answer submission. Results from surveysand usage statistics were also used to improve the design of the application.
