There are many truths in the article. I went through French Immersion from K to 12, and then I also did several years of university at Collège universitaire de Saint-Boniface (now Université de Saint-Boniface). I also spent time in the Faculty of Education at CUSB. I eventually worked for the Federal Government for 10 years, often in French dealing with people from across Canada and immigrants, especially from Africa.
At a
colloque (symposium maybe in English?) in the late 90's when I was in the BEd program, it was discussed then the trouble the French Immersion system was having supporting higher-needs students. The system up to the point had essentially weeded out "undesirable" students (i.e. struggling students) as parents would simply transfer the student out. My parents did that for my brothers when one brother was struggling with reading.
But increasingly parents were demanding access to equal resources that they would obtain in English-track schools, and neither the infrastructure framework nor the staff existed in the French Immersion system. It was then that it occurred to me that my high school had been very, very white, and I only knew of one person with disabilities (they had physical disabilities, not cognitive).
Also because of demand, the quality of French spoken by teachers is actually quite low. I didn't notice it until the colleque and I was surrounded by working teachers. I had spent the past year or two with primarily Francophone students and instructors at the Collège. But a large of number of current immersion teachers came through immersion themselves and speak French as a second language. It shows. I worked very, very hard to lose my Anglophone accent in university.
It does absolutely create a two-tier system, although that is a side-effect and not an end-goal. Is that a bad thing? Not necessarily. Some kids do need to be challenged more, and French Immersion certainly does that.
I don't recall "memorizing rote lists" as the author puts it - I remember a vibrancy of a living language and culture that I didn't have access to at home. I especially value it now because like many Métis our culture was lost at home. Virtually all of my exposure as a child was through school (I grew up in Winnipeg). I struggle now as an adult about how much to "reclaim" for myself and my children, but that's another thread.
