I think it would be useful to display the number of items remaining for review in the top bar of the website (the same way other websites present the number of unread emails or messages).
Right now, I have to go through at least one review session to see the number of phrases to review.
Perhaps if I see the number all the time when I’m logged in to Practice Portuguese website, I will be more motivated to review regularly and make sure that the number goes down to 0?
This can be made optional - for example you could have a settings page where the user could decide if they would like to such number to be displayed or not, and, if the number is above a certain number, let’s say 50, whether they want to see the exact value (e.g. 398) or something like: 50+.
I feel that some phrases are a bit too long for Flash card mode - if I say them without writing them down, after I hear the answer, sometimes I’m not sure if recalled the phrase correctly or not. Maybe some phrases could be available only in the Quiz Mode if they are very long.
When there are different correct ways of answering, it may be possible to add hints for some cards (small icon in a corner of the card) saying, for example, “use personal pronoun”; “fem.”, showing the first character of the word (e.g. “v…” in case synonyms, like e.g. where both “vir” and “chegar” are possible).
One solution would be to allow only shorter, unambiguous phrases to appear in Flashcard Mode.
Another solution would be to create some new flashcards (1 or more if needed) from longer phrase just for the Flashcard mode, having simpler, unambiguous content.
Yet another solution: learn using both modes: in each learning session spend some time using Flashcard Mode and some time using Quiz Mode. The website could even suggest switching the mode after each review session.
I like to make sure I spell correctly the Portuguese words so I wouldn’t like Quiz Mode to disappear but to be available alongside the Flashcard Mode. There are lots of advantages of the Flashcard Mode but for many phrases, in my opinion, Quiz Mode makes more sense.
Some users suggested that they would like a timeout - this could be made optional - you could have a settings page where the user could decide if they want to use a timeout or not. The timeout could be a fixed value or could depend on the length of the phrase.
One more thing - a potential error: After a review, I get a suggestion: “Here’s your next activity: Imperative 2” - I think it should suggest me a new unit which I haven’t learnt yet. (I’ve completed all the lessons on Imperative). The error happens because some time ago I clicked on Imperative 1 lesson by mistake, and when it started, I decided to continue, even though I completed it already a long time ago.
