There are many ways that a blog could be used in a classroom, one of these ways that I think would be great for parent involvement would be to use it to document what their children were doing in school that day. Teachers could post pictures of writing that a student did, math problems that they have been working in groups to solve creatively or science experiments that the students did through the day. Parents could check the blog daily and ask their student more directly about what their student did in school that day so when they get the “School was good. We did nothing” answer, parents can ask specifically about certain activities that happened throughout the day. This might also be a rewarding place to highlight student achievements that might get overlooked. This can then also be a great way for parents to share with other interested family members such as grandparents so that they too can be interested and invested in the work that their student is doing in the classroom. All this being said, if the teacher is being consistent in posting and the parents are regularly checking in on the blog, the student will feel accountable for what they are learning and begin to take initiative in their learning.
Of course there are a few restraints that teachers can also experience when using technology such as blogs to view or assign homework. It is possible that many students do not have access to computers if they are not assigned one by the school. The possibility of excluding a small few would make this mode of communication unfair, and the teacher would have to find another way to have this communication with parents. The possibility of technology failing when you need it would also be frustrating for teachers as they would have to have a backup plan for these situations.
