This document outlines a workflow for designing a classroom response system using Google forms and spreadsheets for mobile learners. The system allows instructors to create a Google form for students to respond to questions, links the responses to a spreadsheet for tabulation, writes HTML and Javascript code to query the spreadsheet and display charts and tables in real-time, and publishes the form for students to access via URL or QR code on their mobile devices. The system provides a free alternative to proprietary classroom response systems using Google's free online apps and the students' own mobile devices.

- 5. Google Account is Required
- 6. Google Documents: Free “Ms Office” in the Cloud • Document resembles Ms Word. • Presenta0on resembles Ms Powerpoint. • Spreadsheet resembles Ms Excel. • Form provides the user interface to survey the students and record the data in Spreadsheet.
- 7. • Google Form The Interface • Google Spreadsheet The Database • HTML and Javascript code The Engine • Internet Browser The VisualizaGon
- 8. 1. Prepare the Google Form. Workflow
- 9. Workflow (cont’d) 2. Link the Survey to Google Spreadsheet 3. Tabulate the responses on the Spreadsheet Note: use standard Excel funcGons such as SUM( ), COUNTIF( ), etc sum( ) counGf( ) Note: it is done from Form
- 10. Workflow (cont’d) 4. Write/modify the HTML-‐Javascript codes Note: • It is wrifen in HTML and Javascript • It involves Google Chart Tools API • It can be downloaded from my website (follow the link/ QR code below) • Minimum modificaGon is expected Gnyurl.com/google-‐crs-‐ver1
- 11. Workflow (cont’d) 5. Publish the Form to the students via URL (recommended to use Gnyurl) or QR code 6. View the result from the browser Recommended browser:
- 12. Gnyurl.com/google-‐crs-‐ver1 Features: • Loading the APIs • Querying the Spreadsheet • Drawing pie-‐chart and column-‐chart to the browser
- 13. Gnyurl.com/google-‐crs-‐ver2 More features: • Drawing table to the browser • UpdaGng the table and charts on real-‐Gme basis • ReporGng error (if any) during querying
- 14. • For more advanced formakng (e.g. super-‐ script, subscript, etc) Google Form can be incorporated into Google Site. • Publish both the Gnyurl (use catchy phrases, for laptop users) and QR-‐code (for “phablet” users) link to the Form. • Do not show the result unGl the quiz is over. • Run trials prior to the lecture. PotenGal issues could be: – Students are unable to access the Form – Browser is unable to access the Spreadsheet
- 15. Resources • QR Code Generator: www.the-‐qrcode-‐generator.com/ • TinyURL: hfp://Gnyurl.com/ • Codes: sites.google.com/a/sps.nus.edu.sg/ – physichronicles/stuff/google-‐chart-‐tools – physichronicles/stuff/google-‐chart-‐tools2 or simply Google “physichronicles dewanto”
