I believe you are correct in that assessment. They see it as sparing the child [and themselves] the pain of learning something which they see as unnecessary and outmoded.
But, of course, there are more reasons to learn cursive writing than being able to read old documents. It's faster to write and the discipline alone -- it's somewhat of an art -- is valuable.
I Seldom take the opportunity to write in cursive these days. My signature however still bears the mark of a person who took some pride in learning to write in the cursive manner.
What will the signatures of todays children who don’t learn to write cursive Look Like?
Are we headed back to the day when scrawling the letter X as ones signature was sufficient?....
