CSE3: Fluency in Information Technology

1. Set up my web page and the moodle page CSE3: Fluency in Information Technology Dr. Beth Simon Computer Science and Engineering http://csemoodle.ucsd.edu CSE B270: Lab Write these down

2. CSE3 Fluency with Information Technology • Why are you here? • Most of you – Freshmen in Sixth CollegeCulture, Art and Technology • Psychology Majors • Computer Science Majors • Anyone interested in getting computingskills that will set them apart in theirfield • You are also…

3. Handout Computer Users! • We all use computers every day, often without thinking about it • Phone, iPod, TV • Car • Facebook, txting • But, what will be next? • What do you need to know about the world that hasn’t yet arrived? • How can you (in your career) help CREATE the new world? • We don’t want you to be YOUR parents in 20 years

4. Nation-wide Effort to Define21st Century Citizens • Why does everyone have to study • Reading • Writing • Arithmetic

5. Nation-wide Effort to Define21st Century Citizens • Why does everyone have to study • Reading • Writing • Arithmetic COMPUTATION

6. Nation-wide Effort to Define21st Century Citizens • Today, a baseline understanding of the power of computers is necessary for: • An informed populace • Breakthroughs in most any field • Successful businesses • Bringing new capabilities to our everyday lives!

7. Your major doesn’t matter

8. What Does This Course Offer You? • Globally-competitive, 21st Century professional • Poised to tackle a broad range of societal challenges and opportunities • In a wide range of professional contexts • “It has given me confidence that I’m able to figure things out on a computer that I never would have thought that I could do.”

9. Change View of Technology • “Now, every time I find myself playing a video game, I actually understand what makes it work. That these games are not magically produced, that it takes time, skill, and sufficient funds to create these games. I appreciate these games more than before taking this class..”

10. Analysis Skills • “Programming allows a person to think more logically, thinking in order and debugging allows the user to gain valuable problem solving skills. • Aspiring to go to law school, thinking logically is extremely important and I think this has helped.”

11. Communication Skills • “In today’s technologically-centered world, using a program like Alice gives us valuable exposure to discussing things technically with other people and explaining clearly what we are trying to do.”

12. Organizational Skills • “Through Alice, I learned to stay organized and structured in anything I do, including studying for other classes. Although at first, thinking with several concepts at a time was very difficult, now I am more confident.”

13. How are you going to accomplish this? • We’ll teach you to “write programs” (in Alice) • But only because it’s the simplest way to interact with a computer • But really you get: • To know what computers can do • How to interact with computers “logically” – at their level • How to communicate effectively in technical situations • How to apply organizational skills in managing data and tasks when using computers

14. Our Primary Goal*: • In the future, • No matter what application you use, no matter the field you are in, • You can apply what you learn in this course to figuring out a new applicationor developing a new way to solve problems in your field using computers. * Primary complication: You may have a limited idea of how exactly this will benefit you.

15. Who am I? • Dr. Beth Simon (call me Dr. Simon) • PhD in Computer Science and Engineering • Computer Architecture, Compilers, Supercomputing • Intel: Itanium compiler optimizations andbranch prediction schemes • San Diego Supercomputer Center:Advise the DoD in spending $$ millionsannually on supercomputers

16. Now hear this… • My primary focus is on teaching THIS class • My research is in how people learn about computing! • I’m VERY excited to have the opportunity to work with you! • Passionate about the value of this class on your future, could you please go out and: • Find a cure for cancer, leukemia, genetically-tied diseases • Develop solutions to enable travel, etc., without using up earth’s resources • Help returning vets manage their psychological issues • Develop the next cool device that changes my life

17. Just So You Know: This class is different • There are 2 CSE3 lectures • They are not inter-changeable, you are expected to attend your assigned lecture • MWF 12-1: standard lecture format • MW 4:30-5:50: active-learning format • We hope you will stay in your currently assigned section • But it is your choice, if you feel strongly, you may switch sections (you’ll need to drop and add a new lab)

18. THE COURSESCOVER THESAME MATERIAL!

19. This class is BIG • But I really, REALLY want to provide you as much individual support as possible! • I WANT you to ask questions! • Have YOU ever asked a question in such a large class?

20. Let’s Practice! • Please, put a hand in the air. • Repeat after me:

21. Let’s Practice! • Please, put a hand in the air. • Repeat after me: I have a question

22. One more time… • Please, put a hand in the air. • Repeat after me:

23. One more time… • Please, put a hand in the air. • Repeat after me: I didn’t get what youjust said, can you explain it again?

24. Rest of Logistics on Class Web Site: Exams, etc. YOUR RESPONSIBILITY TO READ IT Don’t forget to go to lab (starting next week) • Everyone registered for this class by registering for a specific 2-hour lab section. • Start going next week. • Labs are in B270 (CSE) • Go early, it takes time to find it – it’s in basement • If you are ever sick/miss your lab, try to go to a later one (but you must requestpermission!)

25. NEXT CLASS: • You will need to sit in your assigned seat • Room Number and Seat Number on csemoodle.ucsd.edu • If you added class this week, you may not be there yet, check back Thursday morning. • Why? It’s a secret. But, it’s a good thing • You MUST bring your iclicker (bookstore)

26. NEXT CLASS: YOU MUST LOOK UP AND WRITE DOWN YOUR ASSIGNED SEAT ON YOURCALENDAR!!!! • You will need to sit in your assigned seat • Room Number and Seat Number on csemoodle.ucsd.edu • Why? It’s a secret. But, I promise you, you will like what goes along with it. Tutors? • You MUST bring your iclicker (bookstore)

27. Let’s Jump In!But First BY NEXT CLASS TODO • Go to class website and do items under Week 1: http://csemoodle.ucsd.edu (survey, etc.) • Go to the lab (B270) and do Appendix A. • Everyone in B270 is a CSE3 student or tutor • Tutors in B270 randomly today, tomorrow and Wed. if you would like help or to ask questions.

28. Let’s Jump In!But First BY NEXT CLASS TODO • Read Chapter 1 and 2 and do the homework • There’s a homework (small) due before each lecture • Homework has you reading the textbook and “playing” around with Alice • You don’t turn it in, you answer some questions at the beginning of next class (aka a “quiz”) with your clicker

29. Introduction to Alice Alice is named in honor of Lewis Carroll’s Alice in Wonderland

30. Alice • A modern programming tool • 3-D graphics • 3-D models of objects • Animation • Objects can be made to move around the virtual world (a video game or simulation implemented in 3-D) • We recommend you download latest version from the web (if you have your own computer – not required) www.alice.org

31. What will YOU be doing with Alice? • Make movies • Example: Snowman Seeking Snowwoman… • We’ll build this ourselves in a minute! • Make interactive “worlds” • Example: video game • Whack a Mole • Example: user-driven virtual world • Flight Simulator (see Examples with Alice)

32. Important Metaphor: • Two “genres” of challenges in movies and games: • 3-D animation (not programming, art) • Programming (controlling what happens) • Knowing how to program is like knowing how to cook: • If you “can cook”, the ingredients you usearen’t really an issue • Programming: Knowing HOW to Cook • 3-D Manipulations: Just some ingredients

33. We’ll come back to this again…

34. Today: Chapters 1 and 2! • Give you an overview of how to • Design a story • Implement that story using Alice programming language • PLAY your story (called running your program) • Prepare you for lab next week • Where you will make your own story • DON’T TAKE NOTES • Watch and try to understand WHY • These slides (with “ink”) posted on moodle after class • AND Audio Podcast (link on moodle)!

35. Demos: NEVER TAKE NOTES • Preview Slide: • List of things you should be watching for in demo • Notes Slides: • Right after Preview Slide • Your “notes” from the demo • So you can pay attention • BUT: This is still important material!

36. What you will see next: • Make a new World • Adding Objects • 3 Dimensions and 6 Directions • Some tools for managing your 3-D world • Objects: What they are and have Next: 7 Slides are your notes for this demo For you to review and remember what we did

37. Demo: A new world • Create a new world • File  New • Choose template

38. Demo: Adding objects

39. 3 Dimensions, 6 Directions • A 3D object has • 3 dimensions • height, width, depth • 6 degrees of freedom (directions of movement)

40. Techniques and Tools • Mouse is used to • approximately position objects in the scene • Camera Navigation is used to • set the camera point of view • Drop-down menu methods are used to • resize objects • more precisely position objects in the scene • Quadview is used to • position one object relative to another object

41. Objects • An "object" is • any thing that can be identified as unique from other things • How is an object unique? • has a name • has properties: • width, height, color, location • can perform actions (methods): • associated actions it can perform • tasks it can carry out

42. Object Parts • Objects may be composed of parts

43. Demo: Saving a world • Writing and testing an animation is an intense load on the computing system – a crash can occur. • Best solution: • save your world every 15 minutes • Itchy save button • also save to a backup system (for example, a USB memory key)

44. Getting Comfortable with Setting Up Worlds/Objects TODO • Appendix A (pg 311-330) or linked from moodle • Complete on your own in lab B270 in CSE Building, tutors available • BY NEXT CLASS • Or complete on your own computer

45. 2 Sides to Using Alice • 3-D Animation Effects • Important for making your work “look good” (e.g. be what you want) • Issues of how you situate your world/objects • Components of “objects” • Tongue, Arm, Joint, etc. • These are the foods you cook with • Bananas versus milk versus steak • NEXT: How to Cook (program)

46. peter Person paul mary spike Dogs scottie fluffy Programming Concepts: Class • Objects are categorized into classes • Each object is an instance of the class. • All objects in a class have similar propertiesand generally can perform the same tasks.

47. Designing and Implementing* Animation Programs Step 1 – DesignScenarios and Storyboards *Implementing is a computing term meaning, basically, building

48. Step 1: Design • Decide on the problem to be solved • We provide or you choose • Design a solution • We will use a storyboard design

49. Example: Snowman Seeking Snowwoman • The scenario is: Several snow-people are outdoors, on a snow-covered landscape. A snowman is trying to meet a snowwoman who is talking with a group of her friends (other snowwomen.) He says "Ahem" and wiggles his eyes, and she turns to look at him. • Next Design.
