I ask six things of my ACES (for most other things I'm usually flexible):
1. SHORTCUTS. The world has enough corner-cutters. This includes stealing, lying, cheating, or plagiarizing.
2. SHARED SPACE. Show respect for others that use the lab by putting your projects away and leaving your bench area tidy when you leave.
3. DES VISITORS. Show respect for adult visitors that enter the lab by immediately stopping what you are doing, standing and facing the individual(s).
4. NO EATING. Show respect for the lab by not eating in the DES. You may go into the hallway for a quick bite if you need to.
5. AVOID WASTE. Show respect for the lab's resources by not wasting or misusing them.
6. REPUTATION. Show respect for yourself by looking (and speaking) your best. It's the little things keep the doors of opportunity open.
  1. Matches will last exactly 5 minutes
  2. Two qualifying rounds (average points) will determine the initial Tournament seeding
  3. The top 8 seeds move on into the quarter-finals
  4. The Term 1 winner will play the winner of Term 2 in May to determine the Grade winner
  5. The Grade 10 winner will play one match against Mike Ciomyk to determine the 2015 School Champion
  6. Technical problems of any sort with your laptop during a match results in immediate disqualification from the match

It is worth noting, right from the start, that assessment is a human process, conducted by and with human beings, and subject inevitably to the frailties of human judgement.
However crisp and objective we might try to make it, and however neatly quantifiable may be our "results", assessment is closer to art than science.
It is, after all, an exercise in human communication.
Knowledge: Subject-specific content acquired in each course (knowledge), and the comprehension of its meaning and significance (understanding).
Thinking: The use of critical and creative thinking skills and/or processes, as follows:
Communication: The conveying of meaning through various forms, as follows:
Application: The use of knowledge and skills to make connections within and between various contexts.
