Intuitive. Effective. Engender a quiet working atmosphere and support your students while they concentrate on their work and complete their assignments effectively! Noise warning light: The noise warning light provides optical and acoustic feedback on the volume level in the classroom + Adapt the sensitivity to different study groups + Ask your students: the duration of downtime needed for evaluation can be varied. + Often a reminder is enough: Set warnings that remind them (as often as necessary) of breaches of the noise limits before a negative evaluation takes place + Save the settings for different situations or study groups! That way, you can switch, for example, between group and individual work phases. Visual Timer: The visual timer gives your pupils the possibility of grasping the remaining time for a work phase with just a glance + Train a sense of time into your students + Set the "direction" of the timer + The duration can be presented as relative or absolute (on a 60-minute scale) + Set whether an acoustic alarm is to sound at the end of the work phase
