As a parent, I appreciate regular communication from teachers. As children get older, they are less likely to share information from their classes. Middle and High School teachers also have much larger numbers of parents to contact.
Technology can make that communication more practical.
We are reaching a critical mass of parents and students with regular access to the Internet and e-mail. Even those without access at home, often use the Internet at work, school, library or other public locations. The time you save using electronic communication with those parents, gives you more time for voice communication with those not yet online. The ability to type one group name and send an e-mail to multiple people is called a mailing list. You can create a simple mailing list in most e-mail programs.
