General Education Information Approved College Associate Degree GE Applicability AA/AS - Comm & Analyt Thinking CSU GE Applicability (Recommended-requires CSU approval) Cal-GETC Applicability (Recommended - Requires External Approval) IGETC Applicability (Recommended-requires CSU/UC approval) Articulation Information CSU Transferable UC Transferable Methods of Evaluation Objective Examinations Example: Objective Examinations: 1. Q: Turnstiles often contain an odometer-like device that counts the number of persons who have passed through. Argue whether the counter is an analog or digital device. A: There is no correct answer. It can be argued that because the turnstile can only measure "whole" persons, it is a digital device. On the other hand, because the counter is a mechanical device whose dials must physically turn from one count to the next, it could be an analog device. 2. Q: All modern computers work with a system of numbers called ________ ______________. a) Octal numbering system b) Decimal numbering system c) Binary numbering system A: c 3. The use of binary circuitry corresponds to: a) the use of a rotary dial on a telephone b) making use of fingers and toes to count c) the OFF and ON states of a light bulb d) the use of a voice activated answering device A: c Problem Solving Examinations Example: 1. Design a small web site about your family. The web site should contain at least three pages: a top "home" page listing all the members of your family and two or more pages, one for each member of your family. The home page should be hyperlinked to each of the family member pages and vice-versa. Each family member page should contain the following information: * His or her name * A brief description of that person * A list of hobbies * A picture of the person or of one of their hobbies The web pages should make use of a variety of HTML tags, including headings, bold, italics, horizontal rules, centering, images, and colors. Upload your web site to a web server and view it in a browser. Solution: The web pages need to include at least the minimum required tags. It should load correctly in a web browser. Each of the pages should be linked to each other as described. Rubric grading. Skill Demonstrations Example: After doing the laboratory assignment about machine code and parts of the CPU, explain how a computer virus or worm can infect your computer without your knowledge by overwriting the contents of the PC (Program Counter) register. Solution: Because the PC register contains the address of the next instruction to be executed, a virus (or any other malicious program) can cause the computer to execute arbitrary instructions by replacing the contents of register with the address of one of its own instructions. The computer doesn't "know" it is about to execute unwanted instructions. To the computer, this is perfectly normal behavior. Often, the overwriting of the PC register is accomplished with a programming technique called "buffer overruns." Rubric grading. Repeatable No Methods of Instruction Laboratory Lecture/Discussion Distance Learning Lab: Use an online discussion forum to facilitate writing. Require each student to post a minimum number of messages, the substantive content of which demonstrates critical thinking about computer science theory. The messages may be in response to questions posed by the instructor or may be as write-ups at the completion of laboratory assignments. (Objective 13) Lecture: We help the students learn about and visualize various sorting algorithms by using playing cards. Prior to class, the students have read about the bubble and quicksort algorithms. Each student is given a deck of cards to shuffle. Students are then asked to apply the bubble sort algorithm to the shuffled deck. The students should keep a count of the number of iterations. The student shuffles the cards again and applies the quicksort algorithm, also counting the number of iterations. The students then analyze their results to determine which algorithm is faster. We further analyze the algorithms by formulating scenarios in which either algorithm works at its fastest and its slowest running times. Throughout the activity the instructor facilitates the activity. (Objective 15) Distance Learning The instructor will present a video lecture explaining the Bubble sort algorithm through multiple examples. Students will be given an unsorted list integer values to sort using the discussed Bubble sort algorithm. (Lecture Objective 15) Typical Out of Class Assignments Reading Assignments 1. Read the chapter on the history of computing and be prepared to discuss in class. 2. Read the website entitled "Beginner's Guide to HTML." Work through the examples shown by typing them into a text file editor, saving them, and viewing them in a web browser and be prepared to discuss in class. Writing, Problem Solving or Performance 1. Robots are becoming increasingly useful in our society. For example, one can buy a small robot to automatically vacuum a house. We can explore some of the technologies that make this possible using simple robot construction techniques. Design and write a program in Java or RCX to instruct a robot outfitted with individually powered wheels and light and touch sensors to wander around the floor, automatically avoiding obstacles. The robot should not go over any path more than once. The program is finished when the robot finds the black circle located in an arbitrary place. 2. Write a two-page essay describing your personal experiences with malware. Conclude your paper by describing at least two things you can do to remove malware from your computer and/or prevent it in the future. 3. Write a two-page paper tracing the evolution of input devices (punched cards, magnetic tape, disk drives), focusing on how the devices of yesterday have influenced the devices of today.
