Computer Programming II
Textbook Proposal – 2015
Computer Programming II
• Designed to be a transition from Computer Programming I to a more formal
and in-depth look at Java
• Computer Programming I used Alice to transition from an Object Oriented
approach to the Java programming language
Why Java?
• Java is found virtually everywhere and a staple of programming
• IoT initiative – Internet of Things
• Huge push for java to become language for IoT
• Your alarm clock could sync with your coffee pot to begin
brewing
• Jobs, Jobs, Jobs
• Android Apps are written in Java
Examples of Java Based Careers
(Aligned to multiple DASD Career Pathways)
• NASA – World Wind Software Development Kit
• Robotics – Self Driving Cars
• Internet of Things
• Doctor Online – virtual house calls
• Game/App Creation
• Web Design
Need for a Textbook
• Java is a very rich and deep language
• The textbook will provide both the teacher and student the structure
needed for reference as the difficulty increases
• The text selected will lay the groundwork for a possible future AP course
Textbook Review/Selection
•
•
•
Very Few HS Computer Programming Textbooks available
Compared 2 texts based on organizational features,
content, examples, problem sets and other features
Liang provided best resources to supplement book
