Tutorial quiz questions

Description

Add interactive quiz questions to a tutorial. Each quiz question is executed within a shiny runtime to provide more flexibility in the types of questions offered. There are four default types of quiz questions:

learnr_radio

Radio button question. This question type will only allow for a single answer submission by the user. An answer must be marked for the user to submit their answer.

learnr_checkbox

Check box question. This question type will allow for one or more answers to be submitted by the user. At least one answer must be marked for the user to submit their answer.

learnr_text

Text box question. This question type will allow for free form text to be submitted by the user. At least one non-whitespace character must be added for the user to submit their answer.

learnr_numeric

Numeric question. This question type will allow for a number to be submitted by the user. At least one number must be added for the user to submit their answer.

Note, the print behavior has changed as the runtime is now Shiny based. If questions and quizes are printed in the console, the S3 structure and information will be displayed.

Usage

quiz(..., caption = rlang::missing_arg())

question(
  text,
  ...,
  type = c("auto", "single", "multiple", "learnr_radio", "learnr_checkbox",
    "learnr_text", "learnr_numeric"),
  correct = "Correct!",
  incorrect = "Incorrect",
  try_again = NULL,
  message = NULL,
  post_message = NULL,
  loading = NULL,
  submit_button = rlang::missing_arg(),
  try_again_button = rlang::missing_arg(),
  allow_retry = FALSE,
  random_answer_order = FALSE,
  options = list()
)

Arguments

...

One or more questions or answers

caption

Optional quiz caption (defaults to "Quiz")

text

Question or option text

type

Type of quiz question. Typically this can be automatically determined based on the provided answers. Pass "radio" to indicate that even though multiple correct answers are specified that inputs which include only one correct answer are still correct. Pass "checkbox" to force the use of checkboxes (as opposed to radio buttons) even though only one correct answer was provided.

correct

For question, text to print for a correct answer (defaults to "Correct!"). For answer, a boolean indicating whether this answer is correct.

incorrect

Text to print for an incorrect answer (defaults to "Incorrect") when allow_retry is FALSE.

try_again

Text to print for an incorrect answer when allow_retry is TRUE. Defaults to "Incorrect. Be sure to select every correct answer." for checkbox questions and "Incorrect" for non-checkbox questions.

message

Additional message to display along with correct/incorrect feedback. This message is always displayed after a question submission.

post_message

Additional message to display along with correct/incorrect feedback. If allow_retry is TRUE, this message will only be displayed after the correct submission. If allow_retry is FALSE, it will produce a second message alongside the message message value.

loading

Loading text to display as a placeholder while the question is loaded. If not provided, generic "Loading..." or placeholder elements will be displayed.

submit_button

Label for the submit button. Defaults to "Submit Answer"

try_again_button

Label for the try again button. Defaults to "Submit Answer"

allow_retry

Allow retry for incorrect answers. Defaults to FALSE.

random_answer_order

Display answers in a random order.

options

Extra options to be stored in the question object. This is useful when using custom question types. See sortable::question_rank() for an example question implementation that uses the options parameter.

Value

A learnr quiz, or collection of questions.
