2016 Alternative Assessment Practice

This is a Practice task for the upcoming alternative assessment.

The submission date for the actual Viva Voce is Wednesday 1 Feb 2016, 2359 hours.
The task is compulsory, and you are to submit your work via the platform instructed by your teacher.

Topic: Number systems

Objective of Task: 
To demonstrate your understanding of the concepts and calculations through clear articulation and presentation of problem solving.


Instructions (I):
  • This is an individual task. Complete the viva voce practice on your own.
  • This is a reinforcement of similar questions based on the topic covered in class.
  • It will also help you to seek and articulate your understanding of concepts as you attempt to explain your approach and solution to the problem.
  • You should not take more than 1 hour to complete the entire task.
Note: 
You will need to record your work and submit via Google Classroom (Mathematics)


Instructions (II):

  1. Add up the last 5 digits of your NRIC number. This 2 digit number “XX” is what you will convert from a decimal system to a binary system.
  2. DO NOT RECITE OUT YOUR ENTIRE NRIC NUMBER ON THE VIDEO FOR SECURITY REASONS. You only need to state the last 5 digits on video.
  3. Using your birthdate “YY” as another 2 digit number, explain how you will perform the simple arithmetic operation “XX + YY” in binary system.
  • Research on how to count in binary system using the digits “0” and “1”.
  • Explain briefly, in your own words, on how a binary system works. You may choose to use any visualisation tools to help explain yourself.
  • Work out and explain the solution clearly. You may choose to write it out, or use various software like Numbers to write your own script.
  • Do not simply read out the lines of the working. Instead, inform the audience: 
    • how you identify the key information
    • why you choose a particular method to solve the problem
    • explain how the method works
4. Recording
  • You may use QuickTime Player, PhotoBooth or any other suitable media to record your viva voce. 
  • Here are some ways that you can present your worked solution:
    • You may sit in front of the computer and show the working (on papers) as you explain how you solve or problem using the "movie recording" feature in QuickTime Player; or simply "video recording" with PhotoBooth.
      • Click HERE to view sample 1
    • You may present your work in KeyNotePages, PowerPoint Presentation, etc and use the "screen recording" feature in QuickTime Player to do the video recording.
      • Click HERE to view sample 2
      • Click HERE to view sample 3
    • You may also use explain the problem on a whiteboard and have your classmates to help record using a camera or any other methods that you could think of
  • Remember to keep the file size small.
  • For technical consultation, please approach Mr Jonathan Chua, your ICT Teacher.
  • Watch the clip if you are not sure how to screen record your presentation
  • YouTube Video


5. Submission of work
  • Submit your file (video clip) to Google Classroom (Mathematics)
  • Complete this FORM as it is gathering information needed for the markers when assessing your work.
