In the 21st century classroom, technology should be used in an effective and engaging way that facilitates learning. There are a large number of programs and browser-based resources (have a read of my blog post "Tech in the Classroom" for more info) that are specifically designed for music education.
Auralia and Musition by Rising Software are great examples of how technology can enhance and even transform the classroom. They are Ear Training and Music Theory programs that are completely customisable and explore an extremely wide range of levels, styles, musical concepts and skills. These programs would work really well as an integrated section of a unit of work or within the whole music curriculum.
However, technology can also disrupt the learning process and educators must be aware of the statistics relating to it's impact on their wellbeing, and cognitive function. As a result, teachers must be enthusiastic cynics (James Humberstone, 5th October 2018) and understand how we can utilise technology in a positive manner in the classroom. It also means that we must encourage our students to also think critically about technology and its influence on the world.
Sugata Mitra is a professor of Educational Technology, originally from India. He has undertaken many research projects based on the idea of children and how technology can aid them in their learning, specifically in remote and impoverished communities all over the world. He has explored the idea that no matter what skill set, background or situation a child is in, technology will enable them to learn with minimal assistance. Have a listen to his 2010 TedX talk:
Technology has the potential to create empowered learners all over the world, and educators should utilise technology in their classroom.
