Feedback System for a eLearning Tutorial

To design an effective feedback system for an eLearning material

Duration: 1 week

Methods: Persona, Design Sketch, Usability Evaluation

Tools: Illustrator


DESIGN & METHODOLOGY: The problem was to create a feedback system for online learnign material. We were to provide a user with feeback for the multiple choice question she might attempt in her learning material. The multiple choice questions could be of two types - those with single options correct, those with more than one option correct. The actual problem was to let the user know which options she chose, which of them were correct and which of them were incorrect, and which of the options that she did not choose were correct.

We looked at various formats of multiple choice questions. We quickly realized that the interface that provides feedback might look different if the word length of options varied from one word to a paragraph. Hence, there were actually four different scenarios lying at the matrix of number of correct options for a question and the length of answers.

We wanted to design an interface which could accomodate for all the four different scenarios, is easy to understand and does not confuse user. Additionaly, we did not want to "give away" to the user whether the question has one or more options correct by way of marking an answer for the question. We also wanted to provide the user a flexibility to change the answer before finalizing it.

The interface design consisted of options enlisted by choice numbers as "a", "b", "c", "d" etc. Different colors were used to signal different meanings to the user. As soon as an option is marked, its explanation and list item number turns blue. When the answer is confirmed, all the correct options turn green, and marked incorrect options turn red. The list item numbers of all the marked options remain blue. After teh evaluation, we realized that the differentiation by color scheme only would not help color blind users of the system. Hence, to enhance the correct option, we provided it with a "tick mark" besides the correct options which appears besided it, when user conforms her answer.

EVALUATION: To evaluate our design, we made a mid fidelity and low functionality prototype of the interface. We made all possible screenshots with 4 questions exhibiting the four different scenarios. We got it tested by two participants. One of the participants was proficient with computers while other had basic working knowledge of computers but was not confident enough when it came to computers. The test participanst fit our personae well. the aim was to find out how the participants would respond to the question, whether they understand the feedback provided to them, and to check if the interface confused them. We also asked our participants if our interface failed to meet any expectations they woudl have with such a system.
