After one semester I think that Classkick definitely provides useful practice for the students and may even have a beneficial effect on their productive language (speaking and writing) abilities. My LET co-teacher reports that remedial students in her class noticeably improve in spelling, grammar and sentence mechanics. I have seen some particular students in my class make noticeable gains in the same areas, although not every student shows improvement on speaking and writing sections of the 月考.
Classkick supports students' learning by serving as an opportunity for focused, self-directed learning. The students quickly zone in on their assignment pages and work with an unusual quiet diligence, as if Classkick is able to hack the tech-zombie power of iPads and use it for good instead of evil. The "view work" interface (akin to "teacher's view" in Nearpod) is easy to use and students readily notice my intervention and make quick corrections in class. Once students see that some classmates are moving rapidly, their natural competitiveness switches on, and they start trying to catch up. I also patrol the rows of desks to check for inappropriate iPad use, but Classkick is surprisingly good at keeping students engaged.
Since I am feeling fairly confident in the utility of Classkick, I've decided to share some of the assignments that I created so far. Open up a free Classkick account and then click the links to access my shared assignments. Right now we are using Hess Story.com, but in the future I will be making more assignments with content for KangHsian Wonder World.
