I think it makes sense in the context of predicting college success and I believe it would be a better predictor of such success than, say, AP exams or similar. The bigger question of course is exactly how one would do this and I don’t know.
I think you can learn to play an instrument through practice, but it would be hard to a musician without some spark of creativity/inspiration/whatever you want to call it. And really, at its core, music is just math. But clearly there is a difference between algebra and Madama Butterfly.
You learn to write in three ways: by reading, by writing, and by editing. Of course, schools do a little of all of that, but I don’t feel they do it well. Many college students that I have encountered either: 1. Can’t develop a paper beyond the classic high school five paragraph essay or 2. Can’t even coherently write the classic high school five paragraph essay. The latter has become increasingly common and it really comes down to the basics: developing a solid thesis statement and organizing paragraph with a clear topic sentence, evidence, and analysis and, most troublesome to many students, staying ON TOPIC within the paragraph. Many jump back and forth in what reads more like a stream of consciousness. Logical order. Punctuation is also a “nice to have” but I’d settle for coherence. Staying on topic. Making sure your argument relates back to thesis statement. Taking out fluff. Being concise - the student tendency to try to use fancy words they think sound smart or awkward, wordy phrases. Being simple and direct in your language. All of these last things, of course, as part of an editing process. Realizing that good writing is really about good editing. Mercilessly removing off topic ideas and extraneous words that do not add meaning.
And you learn by doing it. Writing, then merciless editing.
And then you need to go further and learn how to integrate sources (while being careful not to plagiarize). Learn how sources can “dialog.” Learn how to handle contradictions in sources. Learn how to create an argument/thesis statement complex enough that you can maintain for, say, 10 pages without rambling.
That is something that bothered my about all of my daughter’s English classes. I don’t think she ever wrote a paper over 2 pages. How do you jump from that to a college paper, many of which start at 5 pages and can go as high as 20? That is a HUGE leap for a novice writer, but it still relies on the basics of thesis statement, well-organized paragraphs without off topic asides, source integration, and merciless editing.
(That was my own stream of consciousness
