1.2. Benefits:

1.2.1. Images or videos are large enough to be seen by everyone in the classroom.

1.7.2. Headphones would need to be removed from the ears every time oral group instructions would be given.

1.8. Application to Learning

1.8.1. Headphones would be used in a computer lab when individual programs are being used that require individual oral instructions. My class would use headphones during the use of the program, "Franklin Learns Math".

2. Input Devices

2.1. Webcam

2.1.1. Used to share digital and still video via the internet.

2.4. Application to Learning:

2.4.1. During a cultural unit study on Italy, I used a webcam in my classroom to video conference with our Italian Penpal, my daughter, Emma. She was studying in Italy for a semester and gladly agreed to be our Italian friend along with our class mascot, Kicks the bear. I used the free internet program called, "Skype" to share communication and images between her and my students. It was a huge hit with the children! They looked forward to seeing and talking with Emma weekly.

2.7.2. Compared to a chalkboard or other forms of non-digital technology, electronic whiteboards are run by power which can fail at times.

2.8. Application to Learning:

2.8.1. I would use this digital technology to play an interactive word family game with a small group of kindergarten students.
