Learning to Compute and Computing to Learn

Classroom Protocol:

This is where you will come every day to find out what we are going to do in class for that day. Every day you are to come to your Quia class web page upon arriving to class, go to your class web page, and follow the directions for today.

Homework Policy:

All assignments will be due on the deadline date given. It is the responsibility for all students to complete their assignments on time. Any assignments received late will not be accepted and a grade will not be given for that assignment.

Accessing your Class Weekly Agenda:

Each week’s agenda and assignments will be updated and posted on your Quia class web page on a weekly basis.  Previous weeks Assignments/Agendas will be provided with a link at the end of the current week’s Class Web Page in case you need to revisit due to an absence, or you’re required to make up, or catch up on your course assignments.

Homework Assignment: Daily homework assignments may be found at the end of each day’s agenda.

F Day – Lunch 11:35 – 11:59

This Week’s Agenda:

UNIT 1: The Internet: This unit begins exploring the technical challenges and questions that arise from the need to represent digital information in computers and transfer it between people and computational devices. In the second half of the unit, students solve problems similar ones that had to be solved to build the real Internet. Students design their own versions of protocols, each one layered on the previous one, in a process that mimics the layered sets of protocols on the real Internet. Topics include: the digital representation of numbers and text, Internet Protocol, DNS, and TCP/IP.

Chapter 1: Representing and Transmitting Information

Objectives

Students will be able to:

• Communicate with classmates about computing innovations in their lives.
• Describe positive and negative effects of computing innovations.

Big Questions

·         Why do computers use binary to represent digital information?

·         How does data physically get from one computer to another?

·         Are the ways data is represented and transmitted with computers laws of nature or a laws of man?

Enduring Understandings

·         2.1 A variety of abstractions built upon binary sequences can be used to represent all digital data.

·         3.3 There are trade offs when representing information as digital data.

·         6.2 Characteristics of the Internet influence the systems built on it.

·         7.2 Computing enables innovation in nearly every field.

Vocabulary

• Innovation - A novel or improved idea, device, product, etc, or the development thereof.
• Binary - A way of representing information using only two options.
• Bit - A contraction of "Binary Digit". A bit is the single unit of information in a computer, typically represented as a 0 or 1.
• Bandwidth - Transmission capacity measure by bit rate
• Bit - A contraction of "Binary Digit". A bit is the single unit of information in a computer, typically represented as a 0 or 1.
• Bit rate - (sometimes written bitrate) the number of bits that are conveyed or processed per unit of time. e.g. 8 bits/sec.
• Latency - Time it takes for a bit to travel from its sender to its receiver.
• Protocol - A set of rules governing the exchange or transmission of data between devices.
• ASCII - ASCII - American Standard Code for Information Interchange. ASCII is the universally recognized raw text format that any computer can understand.
• code - (v) to write code, or to write instructions for a computer.

Monday 10-3-16 – Day D and Tuesday 10-4-2016 – Day E

Standards Alignment

CSTA K-12 Computer Science Standards

CT - Computational Thinking

Computer Science Principles

2.1 - A variety of abstractions built upon binary sequences can be used to represent all digital data.

2.3 - Models and simulations use abstraction to generate new understanding and knowledge.

3.1 - People use computer programs to process information to gain insight and knowledge.

6.2 - Characteristics of the Internet influence the systems built on it.

Objectives:

Students will be able to:

·         Calculate the range of values that can be represented using binary numbers of a given size in bits.

·         Invent a simple communication protocol for sending a list of numbers that represent coordinates on a cartesian grid.

·         Use the Internet Simulator to send the list of points that make up the drawing to a friend.

Activator: Open up your Engineering Journal and review what you entered last class. Review the Standards, Objectives, above, for today’s lesson. Click on https://studio.code.org/ and log in. Locate the Unit 1: The Internet tile and click ‘View course’.

Direct Instruction:

1)   Review the following Internet Simulator Video:

Internet Simulator – Part 2

Guided Practice:

1)   Log into code.org and go to Stage 6 – Sending Numbers

2)   Click on the ‘File’ icon and read the introduction. You will also need to open the corresponding activity guides found at the bottom of the introduction.

3)   Make sure to clearly define with your partner the protocol you will be using on the activity guide which I have printed out for you.

4)   When you are ready each person of each team will secretly plot out the 5 point drawing on the graph activity sheet I have handed out to you.

5)   When ready each person of each team will use the internet simulator to send the coordinates of the points for their drawing to each other. Upon receiving the transmitted numbers you should plot the points on your graph paper and we will compare each plotted graph to see if the numbers were sent and received properly in order to determine how well your protocol worked.

6)   Depending on the results you may need to go back and refine the rules of your protocol to correct any problems that you encountered, and then try again with a different set up coordinates and a new drawing.

7)   Once successful you will need to exchange the rules of your protocol with another team and we will see if the team receiving your protocol can successfully execute your protocol with their partner and successfully use to complete the task.

Additional Questions: Now you should change your protocol as necessary to accomplish the next two tasks

• Develop a protocol that allows the user to send a calendar date (mm/dd). What is the minimum number of bits necessary?
• Develop a protocol that allows the user to send a time (use 24hr military time hh:mm:ss). What is the minimum number of bits necessary?

Assessment for/of learning: Completion of today’s class assignment.

Summarizer: Mr. PC will review each day what each student accomplished and the focus of tomorrow.

Ticket to Leave:

In order to prepare you for your two AP CSP college-board performance tasks we need to get use to reflecting on our daily work and experiences. This is a skill that will prove to be useful when you go on to college, enter the workforce, and even in every aspect of your everyday life.  Every day at the end of class you should save your work, open up your journal, put down today’s date, and provide the following information.

1.   Provide at least on new thing that you learned today – Refer to today’s Objectives

2.   What did you accomplish today?

3.   Indicate any problems or obstacles you experienced

4.   How did you solve the problems or obstacles that you experienced?

Feel free to provide screen shots of your daily work in order to illustrate your day’s activities. Windows provides a Snipping Tool within its provided Accessories that may be used for this purpose.

Homework:

1)   Complete your ticket to leave journal entry. Complete answering the questions found in code.org for Stage 6.

2)   Continue working on your Explore Performance Task. Choose an article from your paper.li and choose a Computing Innovation which you will Explore according to the requirements of the Explore Performance Task. Be prepared to present to the rest of the class on Friday. Students will get a chance to use the Performance Task Rubric and Performance Tasks Samples to discuss and collaborate on ways in which we can improve on our task performance.

Wednesday 10-5-2016 – Day F

Objective:

1)   Understand the explore performance task rubric

2)   Review performance tasks from the college board web site to further our understanding what constitutes a good score from a less than perfect performance task submittal.

Activator: Open up your Engineering Journal and review what you entered last class. Review the Standards, Objectives, above, for today’s lesson. Click on https://studio.code.org/ and log in. Locate the Unit 1: The Internet tile and click ‘View course’.
