Traditionally, class attendance was conducted by professors verbally calling out the names of students. However, recently, with the introduction of the electronic attendance system, it has now become the responsibility of students to check their own attendance. Regrettably, many students often struggle with remembering to mark their attendance in such a system.
To address this, we propose Go-Class, an app with an automatic attendance check system utilizing methods such as BLE beacons. Unlike other solutions such as sending notifications, which may introduce various inconveniences (e.g., unnoticed notifications, noise issues), our solution records the duration of time a student stays in a classroom, allowing them to verify their attendance. It also ensures full attendance as any departure during class time becomes evident.
In addition, to encourage not only attendance but also participation in class, our application contains features that could assist with in-class activities. Class participants (both students and professors) will be able to use group chat features to actively engage in QnA and facilitate team activities more conveniently.
- Students with trouble remembering to take electronic attendance
- Professor wishing to communicate with students more effectively
- Generally, all university class participants (i.e. instructors, TAs, students), especially those taking classes with an attendance check system.
The primary purpose of Go-class is to assist students who struggle with remembering to take electronic attendance, rather than being solely focused on attendance checking. Go-class primarily serves as a means to provide evidence that students were present in class. Currently, there are no such applications like ours, therefore we do not have a competitor.
