LeanDash not only offers several types of questions for quizzes; within each question type, there are myriad options to consider for question flow (one at a time or all at once), feedback (after each question, at the end of the quiz, or no feedback at all, or just for correct or incorrect answers).
You can also assign points for each question, provide hints, and I think also provide some sort of within-quiz navigation or progress bar.
For CriticalThinkingCap quizzes, for the most part, I think I’ll have questions be “graded” one by one, that is, immediate feedback about the correctness of the response, and have the questions come up one by one. I’m thinking I’ll set thing up so that takers cannot go back within a quiz, but they’d have unlimited chances to review/retake the quiz.
I’m basing my decisions on my positive experiences with Duolingo and taking news quizzes from wbur.org and the New York Times. Duolingo, I finally realized, is a series of lessons or units preceded by a brief page of tips and information followed by numerous instant-feedback quizzes.
Below, screenshots of the quiz providers I just mentioned, and the instant feedback for correct and incorrect answers.









All three series of examples provide feedback in slightly different styles. Which one I choose might ultimately depend on what I have time to do, but I would lean towards the color-centric styling of the Duolingo and NYT feedback. And I think a progress bar would be important, as the Duolingo quizzes have at the top of the pages. (Though simple numeric progress such as “1 of 11” as in the NYT quiz might suffice.)
