Pickerator allows you to import class lists and pick students for answering questions in class. The students who are not picked are saved in a leftover file so you can more fairly pick students over several class periods.
The application also has an option to rate the student's response after picking. The student is rated on a scale. The student's rating is saved to the class rating file wth a time and date stamp.
A Utf-8 test file is the sorce for the class name.
As this was developed in China Chinese characters and pinyin are used.
I run this application on an android python interpreter, so it can more easily be used in class
