Exploring the Potential of Smartphones and Tablets for Performance Support in Food Chemistry Laboratory Classes

Increasingly, mobile applications appear on the market that can support students in chemistry laboratory classes. In a multiple app-supported laboratory, each of these applications covers one use-case. In practice, this leads to situations in which information is scattered over different screens and written materials. Such a multiple app-supported laboratory will become awkward with the growth of the number of applications and use cases. In particular, using and switching between applications is likely to induce extraneous cognitive load that can easily be avoided. The manuscript describes the design of a prototype smartphone web app (LabBuddy) designed to support students in food chemistry laboratory classes. The manuscript describes a case study (n = 26) of the use of a LabBuddy prototype in such a laboratory class. Based on the evaluation of this case study, design requirements for LabBuddy were articulated. LabBuddy should work on HTML5 capable devices, independent of screen size, by having a responsive layout. In addition, LabBuddy should enable a student using LabBuddy to switch between devices without much effort. Finally, LabBuddy should offer an integrated representation of information
