Making changes to your classroom environment are only necessary if they benefit students in some way either through their physical or mental health and well-being, or their academic achievement.
It is important to discuss your ideas with your administrator. Having them on board will make your life easier in both the short and long run. They may even be able to offer funds or other supports as you begin your classroom evolution.
It is always a good idea to learn from others who have already implemented some changes. You can get a good idea of the challenges you may face as well as some good suggestions you might want to use in your own classroom. You can explore the videos posted on the Current Implementation page as a starting point.
Start with your administrator as they sometimes have funds available, or they may be able to direct you to grants you can apply to for classroom furniture. Also, many school boards often have storage sites for leftover furniture that you might be able to re purpose for your classroom. There are programs such as the Teacher Leadership and Learning Program that can offer ways of funding your project without having to use large amounts of personal funds.
You might want to start small by including one of more of the seating options suggested on the Key Definitions page. Helpful links to purchase sites are included on the images. You will also want to start scouring local second hand stores and garage sales for interesting items to include in your classroom design. Be sure to check with your administrator to make sure they are approved by your school board.
Swapping desks for beanbag chairs does not mean that students will instantly be engaged and successful. Making changes in the classroom environment will mean a change in your thinking and your classroom management strategies as well. Not only will your classroom environment become more flexible, but you will have to be flexible too. It might mean giving up some control that you think you need to have. For example, seating plans may need to be rethought and control of those seating plans may need to be handed over to the students.
