Implementing a full technology program in the classroom takes time and goes in parts.
The first part is to announce the students' parents that Internet use will take place in the classroom. You will need permission from parents prior to opening the doors of the WWW to their children. Create a permission form or ask the district for one. Keep all signed papers for documentation.
The second step is to make the students accountable for the new material. This is done by creating technology usage agreements between students and the teacher. Upon signing their name, the students make a compromise where there will be consequences if the technology is not used appropriately or ethically. Once all students have returned their slips they also should be kept as artifacts for documentation.
The third step is to develop a set of rules suggested by both, the students and the teacher. This makes the students even more accountable for their actions. List the rules, post them for everybody to see, and ensure that they are visible enough for parents to know that these rules are in place if they ever come to make a complaint or an accusation.
Last is the rubrics. Ensure that students self-monitor using a tech behavior rubric developed by the teacher or by the district. As the student complies with the rules on the rubric, the behavior is checked out. This makes a student responsible for doing the proper thing. Provide feedback each time students comply with the tech behavior rubric, and ensure that this becomes part of the classroom culture by consistently following the same process.
