# IB Computer Science Year 2 Standard Level - August 27 2018 Lesson Notes

## What are we going to learn today?

Welcome to IB Computer Science!

Today we will:

• Review our homework with each other
• Work on diagraming with UML
• Register for treehouse
• Backup files on our server in Germany
```import random

grid = []

# let's make our map.We assume a 25 x 25 map

for i in range(0,625):
grid.append(random.randrange(1,4))

def draw_board():
row = 0
for i in range(0,625):
print(str(i).zfill(3),end="")
row = row + 1
if row == 25:
print ("\n")
row = 0
return

draw_board()
```

• Work on due dates for IA

## What is our home learning?

• Please complete the problem set by our next class. Details are on google classroom.

## How am I being assessed today?

I will assess you formatively today, and make a professional judgement to what extent you understand our learning material. I will use observation, your written work, answers to questions, and contribution to class discussions as data to make my decisions.

I will also ask you to complete a self-assessment which I will use to help me guage how well you think you understand our material in class.

## As a computer scientist, you have:

• Confidence in dealing with complexity
• Persistence in working with difficult problems
• Tolerance for ambiguity
• The ability to deal with open-ended problems
• The ability to communicate and work with others to achieve a common goal or solution

## Credits

Represent by means of a labelled, accurate diagram or graph, using a pencil. A ruler (straight edge) should be used for straight lines. Diagrams should be drawn to scale. Graphs should have points correctly plotted (if appropriate) and joined in a straight line or smooth curve.

Consider the merits or otherwise of an argument or concept. Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument.
