ITC544 Assessment item 1: PeerWise (Value: 10%)

Submission Method: Using the PeerWise website

For this assessment item, you need to register in the PeerWise system. We will be using PeerWise as a place for you to create, share, answer, and evaluate multiple-choice questions with your classmates. You may start by visiting the PeerWise website at :

If you have not used PeerWise before, just click the "Registration" link and follow the prompts. All you need to do is choose a username (students are advised to use their CSU usernames, if possible) and a password for your PeerWise account.

If you have used PeerWise before, simply log in and then select "Join course" from the Home menu. To access the Assessment Item 1, "ITC544 201890", you will need to enter two pieces of information: 1)

  1. Course ID =To be provided in the Interact2 site - Announcement 2)
  2. Identifier = Please enter your CSU Student ID for this course

Using PeerWise, please engage yourself in the peer learning and teaching activities with your fellow classmates by posting maximum 10 multiple-choice questions on (i) the Reading material uploaded in the Resource Section of Interact Site (Introduction to computers), (ii) Textbook Chapter 1: Introduction (sections 1.1, 1.3, 1.4, 1.5, 1.6 and 1.8), and (iii) Textbook Chapter 2: Data representation (sections 2.1, 2.2, 2.3, 2.4, 2.5, and 2.6).

Furthermore, you need to answer questions and post comments on questions/answers posted by the other students. You discuss the topics with other students using the comments. You can also rate other questions and answers posted by other students or the lecturer. This will assist you and your lecturer assess your readiness for study in this subject. The lecturer may contact you if you do not engage with this assessment item.

Please note,you are allowed to post MAXIMUM 10 questions on the three topics. However, there is no restriction on the number of answers and comments you post. Please post quality questions. Please read the following carefully to understand how PeerWise works.

About PeerWise
PeerWise is a web-based repository of multiple-choice questions with alternatives and explanations written by students as part of their required coursework. Activities in PeerWise include developing new questions, answering existing questions, and rating and providing feedback on questions.

After logging in the PeerWise system, the main menu is divided into three sections entitled: “Your questions”, “Answered Questions” and “Unanswered questions”. The role of each of these sections is described next.

Your questions:


This section allows a student to review all of the questions they have contributed to the system. The questions are displayed in a table with columns listing the date the question was developed, the number of responses, and the rating. The table can be sorted on any of these keys. A specific item can be selected from the table, to display details such as how often each alternative was selected and any feedback provided by students who have answered it. There is also a column in the table which displays the perceived difficulty of the question, as rated by students who have answered it. Another column displays whether or not the question is “suitable”, which occurs when it has a rating greater than 2, and the most popular alternative selected is the correct alternative. If either of these conditions is not met, it may indicate that the question is overly tricky, or contains errors. When creating a new question, the contributor needs to provide a question stem, at least two and up to five alternatives, an indication of which alternative is correct, and an explanation of why that is the correct alternative. The explanation is shown to all students who answer the question and serves to assist students who select an incorrect alternative to identify their misunderstanding. Each new question can be tagged with the name of any relevant course topics, which allows students using the system for revision to easily find questions of interest. As soon as a question is contributed, it will appear in the “Unanswered questions” section for other students in the course.

Unanswered questions:

Each question in the system is available to every student in the course. The unanswered questions are organised into a table that can be sorted by the order they were developed, or by the number of responses they have received, or by the rating they have been given. Once a student selects a specific item to answer, the question stem and the alternatives for that question are displayed. The student then selects the alternative they believe to be correct, at which point they will be shown the correct alternative, as suggested by the author of the question, as well as a histogram of all students’ responses to the question. The explanation provided by the author is also displayed, along with any comments previously written by other students. In addition, a simple metric is used to approximate whether the selected answer is actually correct. The selected alternative is deemed to be correct if it agrees with the answer suggested by the author, and if this alternative is also the most popular amongst all previous responses. After receiving this feedback, the student who answered the question has an opportunity to rate it and provide open-ended feedback. The rating scale is an integer between 0 and 5, and is expected to take into account the quality of the question, the distractors and the explanation. The student is also able to rate the difficulty of the question as either “easy”, “medium” or “hard”. Once a question has been answered and rated, it will always be available for review by the student in the “Answered questions” section.

Answered questions:

All previously answered questions are available and can be reviewed at any time. As other students provide responses, the accuracy of the correctness metric improves. The table that displays the answered questions can be sorted by the order in which the questions were answered, by the total number of responses to the question, or by the question rating. A basic leaderboard is also available, which ranks students contributions. It was included to provide some motivation for participation well beyond the minimum requirements for assessment. Tables on the leaderboard display the top rated questions, and rank students on the number of questions they have answered, the popularity of the questions they have contributed, and the popularity of any open-ended comments they have written during the rating process.

This assessment task will work towards assessing the following learning outcome/s:

  • be able to demonstrate and appropriately use computer organisation and architecture terminologies.
  • be able to apply an understanding of data representations and calculations to practical situations.
  • be able to investigate, evaluate and communicate general trends in computing technologies including examples of leading edge developments.

This assessment item has been designed to increase the peer to peer interaction among students as a way to learn and teach each other and to incorporate collaborative learning and teaching. Involving students in the development of questions on topics puts the educational process in focus and empowers students by providing a greater degree of control in reflection, peer assessment, and deep learning. Discussing the construction of questions helps to demystify the assessment of learning outcomes and provides insight into how course objectives are being measured. In addition, providing good feedback is a critical aspect to effective learning. Moreover, commenting and evaluating other students’ questions engages students in a deeper and richer learning experience. This is also an opportunity to self-assess your readiness to engage with this subject.
