Increasingly, teachers rely on computer software and networks to both enhance curriculum management and provide engaging learning opportunities in instruction. New software is enabling more frequent formative assessments to better focus day-to-day lessons on the unique needs of individual learners. Administrators use increasingly complex data management systems to assess students' progress (individually and aggregated) and make data-based decisions to improve student achievement. Together, they are developing school improvement plans to help students achieve mastery of academic standards as their schools face the growing call for even greater accountability at local, state, and national levels. This article is divided into the following sections: Where Do I Start? (model appropriate behaviors and set high expectations for compliance with your school district's Acceptable Use Policy (AUP); avoid shared, generic network logins; allow only district standard devices to be connected to the network; and exercise caution and investigate carefully when implementing any communication strategy permitting indirect connection to your network); May I Have the Keys Please? (Password Don'ts); and I've Been Hacked--Now What? (Key Steps for Containment). The article concludes the most effective protection is an educated staff who realize the power, potential and responsibility they have for being part of the solution.
