Unit 3

Critical Thinking

100

Algorithms can be described as:

Developing a step-by-step solution to the problem, or the rules to follow to solve the problem. 

200

Abstraction can be described as:

 Focusing on the improtant information only, ignoring the irrelevant detail.

300

Pattern recognition can be described as:

Looking for similarities among and within problems.

400

Decomposition can be described as:

Breaking down a complex problem or system into smaller, more manageable parts.

500

Critical thinking can be defined as:

A process that allows us to take a complex problem, understand what the problem is, and develop possible solutions.

Binary

100

Binary counting is in the form of what base?

Base 2

200

What are the first five guide numbers in a binary equation from left to right?

16,8,4,2,1

300

What is the binary code for 31?

11111

400

Please describe why computers use binary code.

Binary code is how computers talk and represent information. 

500

What are the 4 things that have better quality because of an increase in binary code?

Audio, video, images, and text

Communication and Collaboration

100

The act of transferring information from one place, person or group to another, defines what concept: 

Communication 

200

Please define collaboration: 

• To work jointly with others or together especially in an intellectual endeavor.

300

Persistence in doing something despite difficulty or delay in achieving success, describes which concept? 

Perseverance

400

In order for it to be classified as communication, what three things must be present? 

A sender

A message

A recipient

500

What were the names of the two space shuttles that we talked about in class, that fell apart because of a lack of communication and collaboration? 

Challenger and Columbia

Binary

100

10110 is what # in decimal form?

22

200

What do the following words mean: Array, element, sequential order.

A group of numbers. 

The individual numbers inside the group.

Ordering the numbers in sequence from least to greatest. 

300

Please describe the process of a linear search and when using a linear search would be more effective than a binary search. 

Linear search checks each element of the list until the match is found, or the list is completed. A linear search is more useful when dealing with a smaller sample size. 

400

Please describe a binary search and its steps in order, and when using a binary search would be more effective than using a linear search.

• A binary search is also known as half interval search or binary chop.
• A binary search finds the position of a target value within a sorted array.
• For a binary search to work the first step is to order the numbers sequentially.
• The second step is to find a middle element and eliminate.
• We repeat the process until we find our target value.

500

In computer algorithms, a __ is a diagram that depicts a process, system or computer algorithm of instructions in order. 

A flow chart. 

Critical Thinking 2

100

When some one is able to break down the a larger problem into smaller more manageable parts, what concept of critical thinking are they practicing?

Decomposition

200

When someone is able to look at their problems and identify a pattern, what concept of critical thinking are they practicing?

Pattern Recognition

300

When someone is able to separate irrelevant information from a problem and focus on only the important information, what concept of critical thinking are they practicing?

Abstraction

400

When someone is able to create a step by step solution to their problems, what concept of critical thinking are they practicing?

Algorithm

500

Being able to think outside the box when conventional thinking has failed is what critical thinking concept?

Creative thinking
