What is “Coding” ?

• You’ve seen the craze for learning code. But what exactly is coding? Coding is what makes it possible for us to create computer software, apps and websites. Your browser, your OS, the apps on your phone, Facebook, and this website – they’re all made with code.

Audience Engagement:

Ask the audience how many have heard of coding.Ask “How many of you have seen coding before?”

What is “Computational Thinking” ?

• Computational Thinking (CT) is a process that generalizes a solution to open ended problems. Open-ended problems encourage full, meaningful answers based on multiple variables, which require using decomposition, data representation, generalization, modelling, and algorithms found in Computational Thinking.

https://en.wikipedia.org/wiki/Computational_thinking

CT is a process in which solutions to open ended problems are derived using technology.

Discuss the notion that coding is a subset of computational thinking, but not the only subset.

What is “Computational Thinking” ?

• Thinking about and solving problems or completing tasks using technology.

• Coding is a tool used in Computational Thinking. • Building structures is Minecraft is a form of Computational Thinking. • Created spreadsheets and organizing data and graphs is a form of

Learning to code is a process. Here is a goo model explaining different stages. Introduce the terms “algorithm” and “debug” to the group. Explain that an algorithm is like a procedure and “debugging” is like proofreading written work to find mistakes.

So, what is coding?

A ordered set of instructions to solve a problem or complete a task.

Coding is the process of using a language to write an algorithm to solve a problem.

How do you find the factors of a number?

Learn to Code

Write a “pseudocode procedure:

1) Determine a number, say Num. 2) Determine a variable, say X 3) Set X equal to 1. 4) Divide Num by X and look for a remainder. 5) If there is no remainder, X is a factor. 6) Repeat steps 4 & 5 while incrementing X by 1 each time. 7) Stop when X equals Num.

CRITICAL THINKING allows the individual to manage information. Information presented in a multitude of forms from a variety of media. Information that must be filtered and analyzed, authenticated and processed, and eventually must be synthesized in a form that will be useful to the individual. CRITICAL THINKING is PROBLEM SOLVING, the ability to take information and put it to use to create solutions.

COMMUNICATION provides the means by which the individual can present information. Information presented in a multitude of means through a variety of media. COMMUNICATION must be CLEAR and CONCISE, effective and engaging, and eventually be presented in a way that is meaningful to the individual and the audience.

COLLABORATION engages the individual in the world they share through association. Association, that is created to benefit an COMMUNITY and as a means to conduct processes of the world we share. COLLABORATION that includes partnership and teamwork, leadership and assistance, and alliance that serves to benefit the whole.

CULTURE & COMMUNITY encourages the individual to appreciate where we have come from, who we are now and how we can move into the future. CULTURE associates the individual to all that surrounds them: art, drama, dance poetry, history, science, religion, written and unwritten language, technology and the individual themselves.

CREATIVITY provides the avenue for expression. The structure means nothing without function. Therefore, the individual must be capable of CREATING something with the knowledge that they have worked so hard to obtain. It is in CREATING that the individual gains purpose.

CONNECTIVITY places the individual in touch with their world. In today’s existence that is increasingly through the technology that is rapidly changing the way they view their world. Understanding that connections are personal no matter what the means of contact and that humanity must remain in light of how the technology may change for each individual.

French Class

This project was created by a grade 8 student. His task was to demonstrate understanding of French directions. He choose to code a remake of “Zelda” and used Geometry to move the character around the screen.

Suggest this final product is only the “tip of the iceberg” as the process to create it was incredibly challenging and required time and effort.

Make connections to the Geometry in the code. Explain how a negative X or Y moves the character backwards and down.
