Java Teaching Strategies  GUI-first  Object-first  Fundamentals-first (Imperative-first)

GUI-first The GUI-first strategy, starting with GUI and applets, seems attractive, but requires substantial knowledge of object- oriented programming and a good understanding of the Java event-handling model; thus, students may never fully understand what they are doing.

GUI-first The object-first strategy is based on the notion that objects should be introduced first because Java is an object-oriented programming language. This approach, however, has the following problems: – It overlooks the importance of the fundamental techniques required for writing programs in any programming language. – This approach inevitably mixes static and instance variables and methods before students can fully understand classes and objects and use them to develop useful programs. – Students are overwhelmed by object-oriented programming and basic rules of programming simultaneously in the early stage of learning Java. This is a common source of frustration of learning object- oriented programming for freshman.

Fundamentals-first A good introduction on primitive data types, control statements, methods, and arrays prepares students to learn object-oriented programming. Students who cannot write code in procedural programming are not able to learn object-oriented programming. Therefore, this text adopts the fundamentals-first strategy, first proceeding at a steady pace through all the necessary and important basic concepts, then moving to object-oriented programming, and then to using the object-oriented approach to build interesting GUI applications and applets with exception handling, I/O, data structures, internationalization, multithreading, multimedia, and networking.

Java Curriculum Design The computer science curriculum has two important objectives: – To prepare students for immediate employment by teaching them marketable skills; – To train students the ability to learn on their own. This book is developed to foster self-teaching with many complete examples, notes, tips, and cautions. Students should be able to learn on their own after mastering the first 10 chapters.

Java Curriculum Design, cont. Every school is different. Some schools have used the book in one semester, and some have used it in a two-semester or a three-semester sequence. For students with no programming experience, an entire semester of four credit hours could be spent just on the first five chapters of the book, as we do in the first semester of the programming course at Armstrong Atlantic State University. In the second semester, we cover chapters 6-13, 17, and 19.

Interactive Lectures Using the slides, and developing, running and testing programs in the class interactively. Using the slides, you don’t have to write on the board. It saves valuable lecture time. Writing, running and testing programs in the class can hold students’ attention and give them the feedback on how to program instantaneously.
