TJ8 Autonomous work on the blog

I assigned  students some activities to be done at home,but most of them did not do the actvities on their own. This work was mostly done  in the system class.I noticed that students who work best in English class were the same who worked a lot on the blog. However, two or three students whose work had been very low in English class asked me some doubts they had about the activties on the blog. I  also want to highlight that one student who failed almost all the subjects did many activities on the blog on his own at home.
