Knowing that I worked for a while in the private sector, some of my colleagues will also ask me about applications of which I know. Like me, they also often hear the question "When am I ever gonna use this?".
I have also been on several committees to select new text books for math classes in my district.
When I see an application that can help save others time and energy I will create and share it.
(Example - See Google Spreadsheet to tally the responses in the Leadership and Virtues questionnaire from session 1 work that I shared with everyone).
Furthermore, to the new teachers, I have always offered help before being asked and suggestions after.
Ohhh! How could I have forgotten to add this? I have taken the position for the coming school year as the "Online" Algebra 2 content teacher - the first one in our district. And, in fact, I have 2 online students right now who were approved to take the class early. On that note, I did agree to teach them on my own time, because I figured it will help me get the class set up before the regular school year starts.
