Abstract

Development and Usability Testing of a Student Mobile Application for the AIChE Concept WarehouseIncorporating user feedback is imperative for the adoption and continued usage of educationalinnovations in the classroom. We report on the development of an Android-based studentmobile application, a user-suggested improvement for the AIChE Concept Warehouse. AnApple-based mobile application is also in development. Our intent is to share the applications’development and improvement process in the hopes that other innovators can benefit from thelessons learned through our experience.The AIChE Concept Warehouse was developed with the intent of fostering a community oflearning within chemical engineering. The Concept Warehouse is a web-enabled databaseinfrastructure that is designed to promote concept-based instruction through the use of conceptquestions. These concept questions are used in core curriculum courses like Material/EnergyBalances, Thermodynamics, Transport Phenomena, Kinetics and Reactor Design, and MaterialsScience. These concept questions are able to help lower the barrier of using concept-basedinstruction and assessment, which can be used to promote and evaluate student learning in real-time. The instructor is then able to adjust the pace of lecture in response to studentunderstanding. The Concept Warehouse also allows for reflective assessments such as “themuddiest point.”The student mobile application was developed to make it easier for students to submit answersand written explanations to these assessments using mobile devices. Originally, students couldsubmit their answers to conceptual questions using clickers, mobile browsers on smartphones,and laptops. Input via smartphones, however, proved cumbersome because it depended on thequality of the student’s mobile browser and utilized the full-size webpage interface. Theimproved mobile student interface facilitates participation by making responses via smartphonemore user-friendly.After the development of the application, we conducted initial usability tests with students whohad previously used the web-based options for answer submission. In order to gauge usability,we collected usage statistics from student responses to a usability survey. Survey responses wereused to identify student likes and dislikes as well as to compare different available options foranswer submission. These results will be used to improve the design of the current applicationas well as guide our design decisions for the development of the iOS version of the student app.
