1. Hon Wai Leong, NUS (CS5206, Fall 2008) Page L00.1 Copyright © 2008 by Leong Hon Wai Welcome to CS1101 & SOC  Bad news…  CS1101 is hard,  CS1102 is harder  … need I say more?  Good news…  It may be hard, but it is do-able,  And we have many live examples…  Aaron is the best instructor uMultiple winners of Best Teacher Awards

2. Hon Wai Leong, NUS (CS5206, Fall 2008) Page L00.2 Copyright © 2008 by Leong Hon Wai CS1101 outcomes…  Ability to devise computer solutions  Ability to devise (and plan) algorithm  Ability to translate plan to code (Java)  Ability to develop and test programs  Ability to analyze program running time  Awareness of program development issues  History, relevance, and impact of computing  SW Engineering issues  Abstraction skills (data and procedural)

3. Hon Wai Leong, NUS (CS5206, Fall 2008) Page L00.3 Copyright © 2008 by Leong Hon Wai CS1101 outcomes (2)…  Using Java as a vehicle  Writing Java program  Famaliarity with Java syntax, features, etc  Data types (simple, structured, libraries)  Statements (assignment, if, case, while, repeat)  OO features: class, objects, inheritance, etc  Appreciate relevance of mathematics  Discrete math, discrete modelling, graph theory  Develop good programming styles and habits

4. Hon Wai Leong, NUS (CS5206, Fall 2008) Page L00.4 Copyright © 2008 by Leong Hon Wai The Message…. Programming is Difficult, It can be acquired, It is Challenging, YET STIMULATING

5. Hon Wai Leong, NUS (CS5206, Fall 2008) Page L00.5 Copyright © 2008 by Leong Hon Wai  Two slides from my USP module UIT2201: CS and IT Revolution.

6. LeongHW, SoC, NUS (UTT2201: Introduction) Page 6 © Leong Hon Wai, 2003-2008 Figure 1.9 Organization of the Text into a Six-Layer Hierarchy

7. LeongHW, SoC, NUS (UTT2201: Introduction) Page 7 © Leong Hon Wai, 2003-2008 Some Underlying Principles Recurring principles (themes) in CS & IT. They pop-up in multiple places… 1.Multiple Levels of Abstraction  from very high level to very low level 2.Divide and Conquer  also called “Decomposition” 3.One data, multiple views  Different “interfaces” 4.Defining set of primitives (building blocks)  Or basic-operations, mini langugages 5.Power of Iteration  doing something multiple times

8. Hon Wai Leong, NUS (CS5206, Fall 2008) Page L00.8 Copyright © 2008 by Leong Hon Wai  Some slides inspired by the ACM Curriculum Recommendations…

9. Hon Wai Leong, NUS (CS5206, Fall 2008) Page L00.9 Copyright © 2008 by Leong Hon Wai Modern view of Computing…  Theory, Abstraction, Design and Social Context  Three distinct paradigms  Social Context of Computing Theory Abstraction Design Social Context

10. Hon Wai Leong, NUS (CS5206, Fall 2008) Page L00.10 Copyright © 2008 by Leong Hon Wai  Theory Paradigm  Tend to take mathematician’s viewpoint  Concerned with formal definitions, axioms, and theorems  Proofs as underlying media for exploring ideas and thoughts about computation

11. Hon Wai Leong, NUS (CS5206, Fall 2008) Page L00.11 Copyright © 2008 by Leong Hon Wai Modern view of Computing (2)  Abstraction Paradigm  Scientific point of view  Rooted in the sciences (physics, chemistry, biology)  Concerned with formation of hypotheses, construction of models  Making predictions, running experiments, and testing results  Perceiving patterns in midst of details and the formal representation of these patterns  Design Paradigm  Rooted in Engineering  Concerned with system feasibility, costs, efficiency, and alternatives  Accessing requirements, formulating specifications
