About the College

The college's location in the heart of the city reinforces the impact

that it has on the local community.

About the FieldThe widespread everyday use of information systems

reflects a shift in conceptualizing the technology as more social than it was perceived before.

CIS GoalsThe increasing interest in integrating human, communal

and social considerations into traditional information systems curricula has led to the development of new

academic interdisciplinary programs around the globe, with 2 main goals:

CIS - an Interdisciplinary Field"I think our major contribution to

computing was in bringing a liberal arts point of view to the use of computers.

… It was to bring beautiful fonts and typography to people... to help them communicate ...

Our goal was to bring a liberal arts audience to what had traditionally been a very geeky technology and a very geeky audience.“ (Steve Jobs, 1996)

The notion of "community" in CIS is broad, including business communities as well as non-profit

organizations, global or local organizations, public communities, cultural communities, and rural

communities.

As a result of such integrated curriculum, we vision

graduates who are both information-technology-

oriented and social-oriented, and thus can empower the

communities within they live and work.


29

The Computer Science TrackThe discipline of CS is often perceived by IS programs as

one of their supporting pillars.


30



CS methods and ideas, which are at the root of ICT innovations and information systems design processes,

are thought to have the potential to contribute to a greater understanding of those creations.

“Advancing students' understanding of computing has been thought of as critical to developing the needed workforce for the 21st century ”

The College Board, 2012


32

The Computer Science Track

Students in IS programs in general, and in an interdisciplinary program such as CIS in particular, should

study fundamental CS courses in order to acquire the needed broad foundation in computing and consider its

breadth of application.

But How?

• CS track tailored for non-CS majors • Develop an understanding of the principles and practices of

computing• Program without drowning in syntax• Expose students to CS potential for transforming the world

“An unfortunate fact: Java and C++ don’t lend themselves to these rules”

1st Course in the CS Track

What is a first CS course (usually) about?

(1)How to use computers/software packages (for ex., Office)

(2)The CS profession(3)A language, IDE, OS etc. That will get students into the job market(4) Concepts, habits, methodologies of programming


44





Four completely different courses, each valuable for

different reasons and audiences

PBD is a functions-first approach to teaching introductory programming and problem-solving.

PBD emphasizes software engineering practices such as early testing from the beginning.

PBD is combined with the Racket IDE, featuring different language levels, simple syntax, customized error messages, and support for 'algebra of images'

Most importantly, PBD offers design recipes to lead beginner students through a sequence of steps in order

to:(a)obtain an understanding of the problem's nature

(b)design the solution

Design Recipe: Function

Most importantly, PBD offers design recipes to lead beginner students through a sequence of steps in

order to:(a)obtain an understanding of the problem's nature

(b)design the solution

The design of a function proceeds in several steps:

1 Signature (contract) and purpose.2 Define examples (test using check-expect).3 Template and Inventory.4 Code the function body.5 Test and debug until working.

Since ‘Program by Design’ also includes support for transitioning to OOP and libraries for using design

recipes as part of Java IDE, the second course in the computer science track builds naturally on the first while further focusing on the systematic design of

programs and classes
