Learning Activity Package communications Instructor:Name School: Red River College Course: Technology Education Unit: Communications Estimated Time: One Hour LAP Code: A06 Computer Edition
Introduction In a world moving at such a fast pace, it is important for us to stay on top of things. This can sometimes prove to be difficult, because there is so much to learn! Communications is a major factor in what makes the world go ‘round. Almost everything you do revolves around communications in some way. By working through this LAP, you will better understand how communications systems work. Then you will even be able to make your own system! Good luck, and have fun! N

Objectives Upon successful completion of this LAP, you will be able to: 1) Create your own definition of the term communication without any outside help. It must be realistic. 2) Place at least eight from a list of 10 communications terms in the correct order based on their date of invention. 3) State the decade, and by whom Morse Code was invented. 4) Demonstrate and explain how five bits of binary code works. 5) Define the acronym CRTC and describe it’s main objective in not more than one paragraph. 6) Construct a code in about 30 minutes with your partner that is capable of transmitting instructions to them. 7) Have fun participating in the activity Communication Breakdown according to the design brief.

Path Selection Now that you have read the objectives of this Learning Activity Package (LAP), it should be clear what is expected of you. Use the choices below to determine how you wish to learn. NPath 1: “Are you kidding me, I can do all those things in my sleep! I’m going to page 17in this LAP so I can take the self test.” NPath 2: “I don’t even know what language those objectives are written in! I better go to the page6 and start reading over the material carefully.” NPath 3: “I know some of that stuff on the previous page, but not all of it, I’m going to refer to the next page so I can read up on only what I don’t know.” NPath 4: “This LAP is dumb, so I am going to refer to page 24and learn this information from an alternate source.”
Information Perhaps you have already noticed the red text so far mixed in with the black. A term typed in red is one you can find in the glossary on page 23of this Learning Activity Package. As defined by dictionary.com, the term communication refers to “the exchange of thoughts, messages, or information, as by speech, signals, writing, or behavior”. By adding an ‘S’ to that term, you get, “the discipline that studies the principles of transmitting information and the methods by which it is delivered (as print or radio or television etc.). All this means is that communicationSis the field that studies communication. There are many techniques that we use to communicate. N
Learning Activity Package Learning Activity 1 Now that you’ve read the information on the previous page, do the following two activities on a separate, blank sheet of paper. 1) Build your own definition of the term communication. Without showing the term, ask five other people to read the definition and tell you what you’ve defined. If they get it, you must have created a good definition. If not, ask for help perfecting it. 2) Assemble a list of at least 15 ways and things we use to communicate. Place them in order of their origin. Which do you think came first, talking or (talking with) a cell phone? NWhen you’re done, keep on rollin’!
Information Morse Code is a method of communication. It involves sending a message based on long and short marks. These are more commonly referred to as dots and dashes. The Code was invented by Samuel Morse for use with the telegraph machine. It was then used extensively for radio communication starting around 1890. Even though we rarely use Morse Code as a form of communication today, modifications are still being made. In fact, the ‘@’ symbol was added to Morse Code in 2004. Since it’s invention in the mid-1830’s, it has gone through several changes to improve it’s effectiveness, and is now standardized throughout the world. NNext!
Learning Activity Package Learning Activity 2 Now that you’ve read the information on the previous page, do the following activity on a separate, blank sheet of paper. Using the Official International Morse Code chart on the left, exchange coded messages with a friend to practice using the code. See how fast you can write and read messages in Morse Code. Can you do it without the chart? Start thinking about inventing your own code. What would you call it? NAfterward, scope out the next page! 1922 Chart of the Morse Code Letters and Numerals
Information Binary Code is the language which a computer uses to perform operations. Binary is a type of numbering system, only a little bit different from the one we know. The number system we use is called the Decimal system. Starting with 0, we can count up to nine, before having to add a decimal place. Therefore, we also refer to this system as Base 10. In the binary number system, there are only two places: 0 and 1. Once you count to 1, you need to add a decimal place. Therefore, we can call this system: Base 2. This is the basis for pretty much every electronic device you use today. There are other types of numbering systems out there, but these two are enough for now. NNext!
Information You already know that each place in a number is called a digit. The same is true for Binary. It’s called a binary digit, or Bit, for short. You’ve likely heard this term before. Examine the following charts carefully. The chart on the left is the decimal numbering system which you use everyday. The binary system is on the right. You need to know at least five bits of this system, four are shown. NAll done here! Binary Decimal
Learning Activity Package Learning Activity 3 Now that you’ve read the information on the previous page, do the following activity on a separate, blank sheet of paper. Create a chart of binary numbers that go up to 31. This will be five binary digits, or five bits. After you’ve completed this list, practice using the numbers (up to nine) by writing down things like your phone number, birthday, house number and locker combo in binary. Jot down as many numerical terms as you can, to get extra practice. For example, Mr. Gavin typed this LAP when he was 22 years old. Twenty-two in binary is written as: 10110 NWhen you’re done, continue reading
Information The CRTC is the regulatory body responsible for broadcasting here in Canada. It was established in 1968. In the United States, this body is referred to as the FCC (Federal Communications Commission). CRTC is an acronym for Canadian Radio-television and Telecommunications Commission. They supervise and regulate every aspect of the Canadian broadcasting system, including telecommunications companies like MTS, Rogers and Telus. Additionally, they monitor your favourite radio station for appropriateness, and Canadian content. Don’t forget, radio stations here in Canada are required by law to play 35% Canadian Contentbetween 6 am and 6 pm (Mon– Fri). NCarry on!
Learning Activity Package Learning Activity 4 Now that you’ve read the information on the previous page, do the following activity on a separate, blank sheet of paper. 1) Compose a list of ten of your all time, favourite tunes. Do this step before moving onto the next. 2) Using an internet search engine or other source of information, determine what percentage of your favourite songs are Canadian. NNow it’s time for some real fun!
Intro to self test You may be ready for the self test. Read the following to determine your next path choice. NPath 1: “Are you kidding me, I’m gonna kill this test! I’ll jump to the next page so I can take the self test and see how well I know the objectives outlined on page 3.” NPath 2: “I’m still having difficulty figuring out certain topics. I will jump to page 4 and chose another path to learn the rest of this stuff.” (as outlined on page 3)
self test When’s the last time you actually had fun doing a test! When you’re done go to the next page. Down Across Print this page and complete
Evaluation of Self test You should have got 10 or more questions correct on the previous self test. Each answer was worth one mark. NPath 1: “Darn right, I killed that test! I’ll click to the next page so I can take the performance exam and finish this Learning Activity Package. NPath 2: “Aw man, that test was bogus! I didn't even get at least 10 right. I will use another path to learn the rest of this stuff.” Page 4.
