Chat with Your Instructor

This Study Guide will offer some suggestions about how to cover the material in the

class. One of the things you should know, regardless of the class you are taking, is that

the instructor can’t be the sole repository of information for the class – and neither can

the textbook. Technology simply moves too quickly for that to be a viable option. There

is a whole Internet out there. Chances are, someone, somewhere has encountered

whatever problem you are having and has solved it. And chances are, someone who has

solved your problem has posted the solution on the web. It might not be the exact

solution, but it will get you moving toward solving the problem.

Having said that, the more vague an assignment is, the more you will learn from it. The

author of the text will walk you through building a prototypical app and then tell you to

“make it better.” The tutorial sections sprinkled throughout the chapters are very much

like this. We don’t want to inhibit you in any way if possible; we want you to think what

needs to be improved. Of course, there are always students who need more direction and

will need to be dealt with individually. But this is college. Students need to explore – not

be led by the nose step by step.

This book assumes that you have knowledge of basic programming practices. Truly, the

language doesn’t matter. However, you definitely don’t want to be learning at this time

how to write loops and conditionals. You’ll never get to the cool stuff! The exercises at

the end of Chapter 1 ensure that you have the prerequisite skills. If you can’t write these

programs, either review the course previous this one, or at least look into an Introductory

Programming class.

Students often learn from experimentation of the materials in the technology topics. For

this reason, there are many exercises that you can practice. These exercises may require

you to solve a problem, work through a new direction in technology, or even attempt to

predict the future. All of the topics and exercises are meant to be thought provoking and

to help you apply what you are learning.

Finally, you will the exams for each of the lessons. These are taken from the materials in

the book, and are not designed to be researched and answered through any resources you

may locate on the internet.

We wish you an enriching course experience and wish you all the best in your academic

endeavors.
