This is impressive. Students undertake assignments within SL, submit via a digital drop box, have it graded, modified if wished, and returned. Watch the video–this is innovation at its best.
A dropbox for assignments in Second Life. Students submit objects and put descriptors in the Moodle “online text” assignment type. The teacher goes in-world, rezzes and then changes the assignment. The student then may rez the feedback object as well as read comments in the Moodle assignment and receive a grade.
