The modal verb lesson in Spanish is not really finished yet.
Modal verbs has two lessons. A lot of material is crammed into these two lessons, making the unit both harder and less effective.
Most verb forms appear in one or two sentences. Typically each sentence appears with only one form of querer or deber. I'm fairly certain that I learned the sentences, but not the forms of the verb querer. Using different forms of querer in similar contexts would be more effective. For example, the lesson could present any of the forms "she wants to eat, she wanted to eat, she would like to eat, she will want to eat", so that the contrast between the tenses is reinforced.
Multiple choice questions contrast previous learned material ( e.g. choose between comer and hacer ). It would be more useful to contrast the verb forms for the lesson (e.g. choose between quería, quiera, quisiera ).
Good app, but it looks like the lesson quality declines near the end for Spanish.
I agree about those units. I didn't go outside duolingo for actual lessons very often, but for querer, I found a quizlet exercise that helped me a lot. http://quizlet.com/18333558/spanish-iii-repaso-final-querer-definiciones-flash-cards/
I did this one in the "Learn" mode, with "start with term" unchecked, until I could get all 60 without a mistake. As a bonus, I got to learn the vosotros forms :-)
i agree i noticed a big difference when i hit the 50% mark of the tree, suddenly it was a lot more confusing!
I think it has something to do with not as many people making it that far down the tree. Hopefully they see this and something is done. Especially with the Verbs: Subjunctive Past unit. It didn't line up with any studying I did outside of Duo and it only accepted one answer for each question, as far as I knew. I ended up having to cheat a little bit because my answers weren't EXACT. :/
