Writing Programs

i have looked at what the needs of todays writers are. I'm talking about the K12 students who are both getting lots and lots of writing practice thru tweeting and texting but are not learning to clearly structure anything more than sentence fragments.

The biggest tool out there is turnitin which schools use to detect cheating.
There's also massive essay grading programs used for most of the standardized tests.
There are not so many good grammar checkers or pratice tools.

VocabularySpellingCity has a nifty pair of writing practice programs for sentence writing practice and paragraph practice writing.  There is also a great set of short (ie 8 week writing classes) provided by Time4Writing which is used mostly by parents to help with their kids' writing. Often for homeschoolers learning to write.

Time4Writing is an online writing curriculum designed with homeschoolers in mind. In fact, the creation of Time4Writing was the direct result of feedback from users of the Time4Learning Online Homeschool Curriculum who wanted more targeted, individualized writing instruction.  The outcome of that feedback was an elementary writing curriculum, middle school writing curriculum, and high school writing curriculum that covers the key writing skills students need to know by graduation. In addition, the variety of lesson types is designed to keep young writers engaged and motivated to succeed.
