What am I most curious about pertaining to technology in the classroom?

I am curious about a lot in the classroom pertaining to technology. Technology can be used for many different tasks. The thing I am most curious about is how much and how little a teacher should use technology in the classroom. I wonder if teachers should teach off of technology or if they should write notes/ideas on the board. Should students be on laptops or even be provided their own laptop. Is that too much for the student to be glued to a screen on a daily bases? I have witnessed hands on students using computers in a bad way and students using computers in a positive way. That being said I never knew what was the happy medium. I want to learn how to implement technology but it not be too much. Knowing these things can help me become the best teacher I can be and help me work with other teachers to help students do their best in the classroom. I believe that students that use technology all the time are not learning anything from it. Especially in a mathematics classroom, in which I hope to be teaching one day. Having that connection with the students by standing in front of the classroom and giving examples on the board I feel is the best way to teach math, while also using computers for some side work or games to help them better their math skills. Knowing how to implement technology in the classroom is one step closer to becoming a great future teacher.
