Is there any communication app for schools that helps parents and teachers to communicate effectively?

My son’s school used zokrates.

My kids’ schools used schoolloop from middle school through high school. It has pages fro each teacher, a daily calendar email with homework assignments, and a grade book which is updated as often as the teacher posts it.

There’s renweb also. renweb.com

My daughter’s school uses GradeLink.com which is pretty good.

Welcome to Fluther.

One effective tool, believe it or not, is to communicate less frequently. If parents are told (and told repeatedly) about every jot and tittle of the school’s activity and every single assignment that Little Johnny completes well (or doesn’t) – then the “flow” becomes a flood, and parents start looking only for the real nuggets of major import, or ignoring it altogether.

When I was a child in school (and you don’t know me, so you don’t know how much I hate to use that expression, because of how galling it can be to others to hear, but it applies here), the school sent report cards to parents quarterly, notices of school events such as student performances, field trips and the like “in good time” prior to the event, so that parents could plan for them, and “special notices” were indeed special. Parents paid attention to “special notices” as a rule and in my experience, because they really were special in some way.

When my kids were in school – and they’re in their 30s now, so you can imagine how long ago we’re talking – the parents seemed to get “notices” of one kind or another almost weekly. That was too many for me to keep up with, and I was fortunate to have a stay-at-home wife to deal with the major filtering so that I could be available for responding to the events I needed to know about or attend.

Currently I know some teachers, and I have to sympathize with their plight: they send notices of varying importance and content to parents directly via email or using the children as couriers on, it seems, a near-daily flow. I don’t know how anyone manages that when they already have significant other demands on their time and attention.

Aside from that, if the school is an “all-English” school (though I presume from your use of the language that you are ESL: English as a Second Language) their use of the language must be far better than what you used in your otherwise excellent question. Hey, you asked.
