Exchanging files with students

The TI-Navigator™ classroom learning system lets you exchange information with the students in your classes. From TI-Navigator, you can send files to your students and collect files from your students, as well as delete files from your students’ calculators. Your students can send files to you and receive files from you. This section covers the different ways to work with files in TI-Navigator, and includes both instructions for you to use and instructions for you to give your students.

Sending files

You can send calculator-compatible files (such as lists and EDC files) to your students’ calculators from your computer or your calculator. Choosing the location that you want to send files from depends on the location of your files and the number of choices you want about where you send the files. If you choose to send the files from your calculator, then you send files to your whole class forced. When you send files from your computer, you have two choices that are not available when you send from your calculator. You can:
Send files to your whole class, members of the class currently logged in, or to individual students.
Send files forced or unforced. If you send files unforced, students must receive the files from the transfers screen. If you force send the files, the students’ calculators receive the files immediately.
All the files you collect, acquire, or send from a calculator contain a setting in their file properties that specifies where the file came from on the calculator (RAM or Archive). By default, the TI-Navigator software uses the file’s settings to determine where to send the file. For example, if you collected a file from a calculator’s RAM, when you send the file the TI-Navigator software will send it to RAM. However, if you send the file from your computer, then you can select where the TI-Navigator software sends the file by changing the file’s settings in Windows.
You can find the following instructions below:

If you force sent the file, the TI-Navigator™ classroom learning system transfers the file from your computer to the selected students’ calculators. If the students are not logged in, the TI­Navigator software transfers the file upon log in.
If you sent the files unforced, students can receive the file from the transfer screen after they log in to their calculators.(See “Receiving files (student instruction)” on page 50.)
The file transfer appears in the Class Record.
Once students receive the file, they can open it on their calculators.

To send files from your calculator

Starting an activity

Starting an activity involves two steps. First, you must start the activity in the Activity Center tool to make it available for your students. Once you start the activity in the Activity Center tool, your students can then join in the activity from their calculators. Below you can find instructions on both starting the activity in the Activity Center tool and instructing students on joining the activity from their calculators.
To start activities in the Activity Center tool
1. If you have not already done so, configure the activity or load saved activity settings. (See “Configuring activities” on page 71.)or (See “Loading activity settings” on page 94.)
2. From the Contribute drop-down list, select the type of data you want to collect from your students.
3. Click

To instruct students on joining activities
Once you start an activity in the Activity Center tool, your students can join the activity from their calculators. You can use the following instructions to instruct your students on how to join an activity you have started.
Note: As the teacher, you can also use the steps below to join the activity
from your calculator. When you join an activity from your calculator, you participate in a student role.
Student Point of View: The steps below are from the student’s
point of view.
1. If you have not already done so, log in to your calculator. (See “Logging in to TI-Navigator (student instruction)” on page 13.)
2. On the TI-Navigator™ Home screen, select
