Lesson synopsis

open book with paintingsOne of the most important ideas in modern computer science is the object. Without objects, modern window-based user interfaces and much of modern film techniques would be almost impossible to do. Objects allow designers and programmers to encapsulate information so that other details can be ignored when necessary. This lesson shows how an object made of connected parts can be animated by displaying it as a series of graphic images. This lesson can be done entirely off computer by building a traditional flip book with a PostIt note pad, or entirely on a computer using slide production software (PowerPoint, Keynote, Google Drive Slides). Or you can combine them for a very rich experience.

Age Levels

11 - 13 years

Objectives

Introduce students to:
how an object is a collection of parts.
how an artist’s manikin is an example of an object.
how computer animation is based on the simple flip book.

Anticipated learner outcomes

Students will be able to:
use the concept of object to create a drawing of something with articulated parts.
create a flip book animation either with PostIt pads, or by using standard slide production software.
explain how thinking in terms of an object allows them to work more efficiently.

Optional Writing Activity

How does thinking in terms of objects that have parts help you organize the process of creating a flip book animation either on the computer or with PostIt pads?
Router
Sandra Lerner

It is difficult to imagine a time when computers were not capable of sharing information and resources with great ease. Sandra Lerner pushed the boundaries of network computing as one of the co-founders of Cisco Systems, which introduced one of the first commercially viable routers. The router was born while Sandra was working at Stanford University in the 1980’s after earning her Master’s degree there in Computer Science. To avoid the tedious task of transferring information between computers using floppy disks, she and co-founder of Cisco, Leonard Bosack, created a local area network, or LAN, between their campus offices using a multiprotocol router that Bosack developed. Shortly thereafter the pair started Cisco Systems, and began selling the router which was a success, because it could work with so many different types of computers. After Leaving Cisco in 1990, Lerner started the trendy cosmetics company Urban Decay and became a philanthropist and avid activist for animal rights.

Jean Sammet

Jean E. Sammet was one of the first developers and researchers in programming languages. During the 1950’s - 1960’s she supervised the first scientific programming group for Sperry Gyroscope Co. and served as a key member of the original COBOL (COmmon Business-Oriented Language) committee at Sylvania Electric Products. She also taught one of the first graduate programming courses in the country at Adelphi College. After joining IBM in 1961, she developed and directed the first FORMAC (FORmula MAnipulation Compiler). This was the first widely used general language and system for manipulating nonnumeric algebraic expressions. In 1979 she began handling Ada activities for IBM’s Federal Systems Division. Ada is a structured, object-oriented high-level computer programming language, designed for large, long-lived applications, where reliability and efficiency are paramount. Jean has a B.A. from Mount Holyoke College and an M.A. from the University of Illinois, both in Mathematics. She received an honorary D.Sc. from Mount Holyoke (1978).

Mark Dean

If you have ever used a PC with a color display you have been acquainted with the work of Mark Dean. After achieving a Bachelor’s degree in electrical engineering from the University of Tennessee, Dean began his career at IBM. Dean served as the chief engineer on the team that developed the first IBM PC, for which he currently holds one third of the patents. With colleague Dennis Moeller, he developed the Industry Standard Architecture (ISA) systems bus, which enabled peripheral devices such as printers, keyboards, and modems to be directly connected to computers, making them both affordable and practical. He also developed the Color Graphics Adapter which allowed for color display on the PC. Most recently, Dean spearheaded the team that developed the one-gigahertz processor chip. Dean went on to obtain a MSEE from Florida Atlantic University and a Ph.D. in electrical engineering from Stanford University. He is a member of the National Academy of Engineering, has been inducted into the National Inventors Hall of Fame, and is the first African-American IBM Fellow.

Dr. Sue Black

Dr. Sue Black has demonstrated the power of social networking. She used Web 2.0 technologies to help raise awareness of, and critical funding for, Bletchley Park, the UK World War II center for decrypting enemy messages. She has also been an active campaigner for equality and support for women in technology fields, founding a number of online networking platforms for women technology professionals. A keen researcher, Dr. Black completed a PhD in software measurement in 2001. Her research interests focus on software quality improvements. She has recently won the PepsiCo Women's Inspiration Network award, been named Tech Hero by ITPRO magazine and was awarded the first John Ivinson Award from the British Computer Society. In 2011 Dr. Black set up The goto Foundation, a nonprofit organization which aims to make computer science more meaningful to the public, generate public excitement in the creation of software, and build a tech savvy workforce.

Turing machine
Alan Mathison Turing
Alan Mathison Turing

Did you know that computing has been used in military espionage and has even influenced the outcome of major wars? Alan Mathison Turing designed the code breaking machine that enabled the deciphering of German communications during WWII. As per the words of Winston Churchill, this would remain the single largest contribution to victory. In addition, he laid the groundwork for visionary fields such as automatic computing engines, artificial intelligence and morphogenesis. Despite his influential work in the field of computing, Turing experienced extreme prejudice during his lifetime regarding his sexual orientation. There is no doubt that computers are ubiquitously part of our lives due to the infusion of Turing’s contributions.
