getAnswerStatus

public boolean getAnswerStatus()

returns the answer status, determining whether the question statement was correct (=true) or not (=false)

Returns:

the answer status; true for a correct and false for an incorrect statement

getFeedbackForOption

public java.lang.String getFeedbackForOption(boolean userChoice)

return the didactical feedback for the user answer

Parameters:

userChoice - if true, the returned String will be the feedback for the user's choice of the "true" button; else, it will the feedback for a chosen "false" button.

Returns:

the didactical feedback associated with the given user answer.

setAnswerStatus

public void setAnswerStatus(boolean answerStatus)

sets the answer status to the value passed in

Parameters:

answerStatus - if true, the question statement was correct, else it was incorrect

setFeedbackForCorrectAnswer

public void setFeedbackForCorrectAnswer(java.lang.String text)

assigns a text to be shown if the user answered "true"

Parameters:

text - the text to be shown if the user selected the answer option "true"

setFeedbackForIncorrectAnswer

public void setFeedbackForIncorrectAnswer(java.lang.String text)

assigns a text to be shown if the user answered "true"

Parameters:

text - the text to be shown if the user selected the answer option "false"

setFeedbackForAnswer

public void setFeedbackForAnswer(boolean answerOption,
                                 java.lang.String text)

assigns a text to be shown if the question was answered in a certain way, i.e., the feedback to be given for the answer "true" if the answerOption parameter is true, and the feedback for "false" if the parameter is false.

Parameters:

answerOption - determines if the feedback is for the chosen answer type "true" or "false". Note that this is not the same as for "correct" or "incorrect" -- the answer option "true" will often be the incorrect choice. The parameter thus describes the user's chosen answer, not the correctness of that answer.

text - the text to be shown if the user's answer was incorrect
