Why diminishing drill?
The standard question load per exercise is great. When I want to focus on specific words, however, the initial question load is half the standard amount. From there if I continue to practice that word it diminishes further, to the point where I only get two questions per exercise.
It really helps to be able to focus in and concentrate on conjugates and their myriad forms, so I would recommend that the team consider increasing the number of questions on these exercises to allow for better learning when it comes to the challenging aspects of language such as conjugation and declension.
From what I have gleaned in the year and a half I have been on Duo, the Duo people keep VERY close tabs on all sorts of things, and when things get more challenging (more questions but still only three hearts, for example) more learners drop out. It seems Duo is walking the line between keeping things, for lack of a better word, 'academic' enough for some users and 'gamey' enough for others. Nearly every 'serious' Spanish learner I have encountered on Duo can tell me the non-Duo resources they use for vocab, grammar, verb conjugations, conversation, etc.
Thank you, and I have been using About.com's language resource as well. I wonder if it would affect the gaming aspect of the system adversely if we could chose the number of exercise questions for a given word or phrase. Perhaps let us voluntarily choose not to receive hearts or xp and just set a question load of something like 25 or even 50 questions to allow us to better drill the concept into our heads. I know my learning style, and rote/repetition is a very important part of how I absorb nuanced content like grammar.
Yep, and there are several loooooong threads about Duo's perceived lack of emphasis on grammar. But, with millions of users and the competitive fire many users have, it seems anything that would 'personalize' the program would complicate things and upset someone. :) Several people complained about people giving lingots to folks that had not 'earned' them, for example.
