I know this is not a favored view, and can also make many people angry with me for expressing it.
Over this last month or so, since my account was updated to the new tree, I have been doing a reasonable amount of review of the new tree.
You can get a bit of a picture of that at viewtopic.php?t=6618-duolingo-path-overview-199-units.
The document that Duolingo has provided to educators I do consider is superior to what was available for the older tree versions. Though it has also taken me some time to get used to it - and I feel I still am doing that.
On Duolingo's assessment the new "path"(snake) these are the levels regarding assessment to CEFR levels :
A1 - Units 1 to 44
A2 - Units 45 to 80
B1 - Units 81 to 158
B2 - Units 159 to 199
I have not a clear picture of the relationship of the new course to the old trees, as I see I need to adapt what I do, and the way I do things to adapt to using the resources of the new tree. Including aligning the learning of verb conjugations and importantly many other grammar topics to align with accessing / being able to target appropriate units in the new "path"(snake). And also working out how to jump, and assist others to jump to areas of study and interest for their learning.
The think what I dislike the most about the "path"(snake), is it's lineal nature, which makes it harder to adapt for use from other resources and interests and needs that a learner may have for reasons outside of this now strict path. And I see my interest is how to assist in serendipitous learning relevant to the real world for learners. There is a lot I like about the new "path"(snake), but as also with change, there are also other things I am not so impressed with.
Yet, a rose by any name would smell as sweet. And I think this new path does have many benefits, and even new pleasures.
And the resources of Duolingo continue to also impress me - especially as they are free. But also as Duolingo continues to expand on them. I have picked up that there will also be new stories coming out. That they are going to continue to support and develop the podcast resource. Note that is one well worth spending some time with. (https://podcast.duolingo.com/).
I still think they could do more at giving students an idea of their real progress - what their real accomplishments are. And also to teach grammar topics better to the learner. Yet - I see in so many posts - on all sorts of platforms - how effective the bells and whistles "gaming" engagement of Duolingo is a major motivator for prestige of so many learners. And that also has great value and encouraging learners to apply themselves.
Yet as I well know, with any system, people can "game" it, and avoid really learning and understanding - especially if the real reason they are learning is for prestige rather than understanding and versatility. For true learning of .... well .... almost anything - but especially language - relying on only one source for your learning is less than desirable for competency and understanding in the real world.
