Evolving Classroom Education: Where is K-12 Technology Headed?

In his blog "Evolving Classroom Education: Where is K-12 Technology Headed?", Matthew Lynch discusses the importance of the action(s) that needs to take place in order to integrate technology into classrooms.  Lynch suggests three types of methods: BYOD, NUI, and PLE.  BYOD is known as Bring Your Own Device.  With this method, students are encouraged to bring their smartphones and tablets to school for classroom use.  NUI is known as Natural User Interfaces.  As defined in the article, NUI uses the body's movement to provide outcomes.  Today, there are many devices does this such as Nintendo Wii, Xbox Kinect, and Siri.  The greatest advantage about NUI is that it plays a huge role for students who are blind, deaf, autistic, and physically disabled.  PLE is known as Personal Learning Environments.  This type of method is student centered.  It focuses on  allowing students to choose resources through electronic formats for individual learning that best fits their learning style and pace.
Ultimately, Lynch provided good points that could help schools stay within budget on technology.  However, I do not agree with one of the three methods.  The idea of students bringing their own smartphones or tablet devices to school is asking for problems to happen within the classrooms.  Students may not pay attention to the teacher because they are busy playing Candy Crush or updating their Twitter accounts.  It is already bad enough in college, but to ask for students in K-12 to bring it to school   As for NUI and PLE, I would actually like to see these to take place in classroom(s).  I think NUI is a great way to incorporate students with challenging disabilities to stay connect and still be able to participate in the classroom. I also think PLE is another great method that allow students to learn in a way that best fits their style and pace.  Not all students learn the same way, so for students to use technology to help them learn things at a rate that is appropriate for them is fantastic.
