A few years ago it was suggested to me to use musical alarms for the beginning and end of class time together. Our school is a “No Bell” school beyond the beginning and end of our day. Yet the audio cues are important to me and my students. I found a Chrome Extension tool called “Cool Clock” that fits my need perfectly and has emerged as a major classroom management tool for staying on task.
I have “Cool Clock” set to go off at the beginning and end of class, playing the tv theme song from Friends. The length of the song is 43 seconds which works perfectly for the students and class to be reminded it's time to get ready for the instruction. This reminder extension has become part of my beginning of the year routines. The music encourages students to have their device closed and focus on our agenda screen for what learning lies ahead. It is slick and works surprisingly well.
I have created a short video on how to set up this Chrome Extension tool for your classroom. It is fairly fast, efficient and easy to turn on/off as needed with a modified schedule day. Here is the Setup Video for the Cool Clock Extension. I hope you find the same success in your room.
