Division Experimentation & Lab-Oriented Studies
Laboratory activities are ubiquitous in schools and universities and allow students to investigate the relationship between real-world phenomena and theoretical models in a controlled setting. As well as traditional ‘hands-on’ laboratories, both simulations and increasingly remote laboratories are widely used and their educational benefits have been supported by the research. Despite the prevalence of laboratories across educational programs, both the number of new experiments being designed and the sharing of the design of these new experiments has been more limited than might be considered desirable. However, developments in sensor and actuator technology, fuelled by the increasing interest in the Internet of Things (IoT), mean that more data is accessible from a range of ‘things’ which have been specifically designed to easily share information about themselves and their environments. This presents an opportunity for the design and delivery of laboratory activities based on the real world data available from IoT enabled ‘things’ without long lead times and expert technical knowledge of the sensors or interconnection technology. This ‘non-expert’ design of sensor based laboratories has application for both remote and hands on laboratories in schools and universities, but is only valuable if teachers are both willing and able to make use of the solutions. This paper reports on the results of a case study into an educational mobile application which makes use of IoT enabled wireless sensor technology to allow educators to easily design, deliver and share laboratory activities based on real world sensor data. Of particular interest is whether teachers would be willing and able to make use of the framework. The prototype developed is an Android application that makes use of TI SensorTag sensors and provides a low cost, flexible solution for the rapid non-expert design, deployment and sharing of laboratory activity design and data. Initial feedback from high school teachers and students using the application shows positive results, but also suggests key aspects that would need to be incorporated in approaches to supporting teacher engagement.
