Today in class, we will:

- Review yesterday's lesson on binary

- Draft and submit at least two proposed test questions with answers. At least one of them must include creating an algorithm that uses iteration. The submitted answer must include an example algorithm and flowchart.

If time allows, we will reread the online text section discussing DDoS attacks and do a DDoS attack simulation in class.

Today's applicable Oklahoma curriculum standards:

(L1.AP.A.01 Use algorithms (e.g., sequencing, selection, iteration, recursion, etc.) to create a prototype to provide a possible solution for a common problem. )
(L2.NI.C.01 Compare and refine ways in which software developers protect devices and information from unauthorized access.)

Today in class, we will:

- Work in groups
- Discuss binary digits (bits) (2 mins)
- Watch a magic trick (8 mins)
- Discuss the magic trick and try to determine how it was done (5 mins)
- Discuss how the magic trick was done whether the magic trick will work if adapted (10 mins)
- Watch a visual demonstration of the concept of binary digits (9 mins)
- Brainstorm ideas in groups to ensure data correctness (10 mins)
- Discuss your groups' ideas with the class (5 mins)

(L2.NI.C.01 Compare and refine ways in which software developers protect devices and information from unauthorized access.)

(L1.NI.C.03 Recommend security measures to address various scenarios based on information security principles.)

Monday, September 10, 2018

Today in class, we will:

- Discuss designing a more secure algorithm than Ceasar Cipher

- Read text sections on confidentiality in our online text

- Discuss the CIA triad (confidentiality, integrity, availability)
- Discuss Vigenere cipher and view an explanatory video

- Use a Vigenere cipher tool as group

Friday, September 7, 2018

Today in class:

-- We will study vocabulary on Quizlet for the first ten minutes of class.

-- Then we will take the the vocabulary test.

-- Then we will discuss yesterday's assignment on decoding.

-- Then we will discuss your submitted flowcharts.

-- Then we will move to the lab for flowchart product demonstrations.

Thursday, September 6, 2018

Today in class:

-- Please sit with your groups and do the "Encoding Exercise" at the end of the Encryption section in our online text. (10 minutes) 

-- Then please decode the following. (YOU MAY NOT USE AN APP OR ONLINE TOOL, ONLY YOUR OWN INTELLECTUAL ABILITIES. :-) ) This is a competition and the first group to email me the correct decoded messages and key for deciphering the code for all five will win a prize! (20 minutes maximum)

1. PGGTFU CZ POF
2. DRO YPPCOD SC DOX
3. JC IJ TJP CVQZ YDNXJQZMZY HT NZXMZO
4. LUJYFWAPVU PZ MBU
5. MVKZGXBQWV QA ABQTT NCV

-- Next, working in your groups, write a paragraph response to, “Consider designing a more sophisticated algorithm that would be more secure than the Caesar cipher. What sequence of steps could you perform to securely encode your message that would make it harder for an ‘Eve’ to crack your code?” Then email it to me before the end of class. (15 minutes maximum)

-- Then please read the TOPIC: Cybersecurity section in our online text, paying special attention to the CIA triangle (confidentiality, integrity, availability). Please read through the end of the section on Social Engineering. (Do not do the exercise at the end of this section.) If you do not finish reading in class, please finish reading this tonight as homework.

***Please be sure to include all your group members' names on all you submitted work.

***Please remember we have a vocabulary test tomorrow. If you have additional time in class, after completing today's assignments, you may study for the vocabulary test.

Today in class:

Please work in your assigned groups. Please manage your time wisely. From the beginning of class, you have 15 minutes to review the text, example flowchart ("Hey Jude"), and link for flowchart symbols and meanings, and project instructions and brainstorm to choose your topic for your flowchart. For the next 15 minutes, work with your groups to complete your flowcharts. For the next 10 minutes, exchange your flowchart with another group and provide written feedback, noting both strengths, weaknesses, and suggested improvements. *Your group will be graded not only on your flowchart, but also on the feedback you provide the other group, so please be sure to put all group member names on your project as well as the feedback you provide the other group. For the last 10 minutes of class, we will read our text "CODING SKILLS: Encryption." 

This means second hour will exchange projects for review at 9:24 a.m. and sixth hour will exchange projects for review at 1:46 p.m.

Please thoroughly review the instructions below before beginning. 

Review the text on flow patterns and flow charts. Discuss the example flowchart illustrating how to sing "Hey Jude" and how it could be better. It is flawed. Then, as a group, create a flowchart illustrating a process, such as making a great peanut butter and jelly sandwich. (Use the explanation of common flowchart symbols and meanings found at https://en.wikipedia.org/wiki/Flowchart#Building_blocks to choose your symbols.) 

Each flowchart must meet the following requirements:

-- Must have a least six steps. May have more. 

-- Must use sequencing, selection, and iteration. Must use either a definite loop or an indefinite loop. Sequencing, selection, iteration, and definite or indefinite loop must be labeled within the chart.

-- You may bring examples to illustrate your flowchart on Friday. Some suggestions during sixth hour yesterday were how to bake brownies, how to make pizza, getting ready for school, and how to apply makeup. Enjoy!

Your flowcharts and feedback to the other group are due by the end of the hour.

Tuesday, September 4, 2018

Today in class:

-- We studied vocabulary set two on Quizlet and took the accompanying test.

-- We studied vocabulary three on Quizlet.

-- We read the section on Flow Patterns in our online text and discussed flowcharts.

-- Reading the section on Algorithms was assigned as homework.

-- Sixth hour brainstormed ideas for process flowcharts. Second hour will do this Wednesday, and both classes will complete the flowchart project.
