Basic Phone Interview Loop
Interview Loop with <Gather>
- After you’ve uploaded the poll_gather.xml and response.php files to your TCNJ web account, log into Twilio, click into your number detail page, and edit the Voice request url for your number to point to ‘poll_gather.xml’.
- Call your Twilio number.

Storing Responses to a File
- After you’ve uploaded the poll_gather_data.xml, record_data.php and data.txt files to your TCNJ web account, log into Twilio, click into your number detail page, and edit the Voice request url for your number to point to ‘poll_gather_data.xml’.
- Call your Twilio number.
- What happened?
- Now point your web browser to http://www.tcnj.edu/~your-user-name/your-folder/data.txt

*A note on file permissions – these examples write the callers’ selections to a comma-separated file (csv). You’ll need to set the file permissions on your data file to ‘read & write’ with settings 666.

Challenge
- Break up into your groups and compare notes on your list of questions for your Partner Organizations from last week’s assignment.
- Using the Phone Poll design pattern, create a Phone Poll app that asks 3 closed-ended questions and one open-ended question.
- Be sure to store the responses in a comma-separated (csv) file on your TCNJ web account.
Assignment
Partner Organization Interview and Follow-up Survey
- Meet with your team and combine all of your questions from last week’s assignment.
- Discuss your questions and determine if there are any other questions that need to be added.
- Refine your questions to fit into either the closed- or open-ended question type forms and organize them into 2 groups: initial interview questions, and secondary & followup questions
- Create a one-sheet list of your initial interview questions in preparation for a call with your Partner Organization (call time to be determined).
- Using the secondary & followup questions list, create a TCNJ Qualtrics survey as a starting point for a followup survey to your initial interview call.
Design Notebook
- Create a new page in your Design Notebook and label it “Interview & Survey” and today’s date.
- List the initial interview questions you and your group came up with in preparation for your initial interviews.
- Include a link to your TCNJ Qualtrics Survey.
*Assignments are due before class begins on Mondays. Be prepared to present your work in class for discussion.
