I feel compelled to share the things I know. Why? Because only a very small percentage of what I know and do came from an original idea of my own design. Any teacher who is honest with him/herself will tell you that ideas come from everywhere and borrowed. I will try to give credit when its due. Besides, as teachers we all have the same goal: To provide the best possible education for our students. I believe collaboration and discussion are critical for that.
Another reason I feel compelled to share ideas. When I first began teaching, I knew nothing. College only gets you in the starting block. A first year teacher doesn't have files with theme activities or ideas. That has to be collected over time. My first two years were dependent on a few individuals that helped by offering their resources and experiences. The only thing I realized I could give back was my knowledge of technology and the ability to help others use it. So even though, I've gotten much better as a teacher, I still want to do my part to voice my experience and expertise in education.
