Goals of the course: There are two important elements to the course:   Principles (20%- 30% of the course):   Understanding the concepts behind computers   Practice (70%- 80% of the course):   Learning how to use computers

The practical goals of this course: To teach you how to use the following:   Word processing   Spreadsheets and databases   Web authoring tools   Presentation software   Multimedia: animation and imaging applications   Basic operating system skills You will be encouraged to use the computer as much as possible, because this will be useful for you in your college career and beyond.

Principles: Exploring concepts behind computers, Networking, and Internet and the web The development of computer technology is one of the great stories of the twentieth century. All educated citizens should know about computers. We will talk about:   Computing Hardware   History of computing, Internet and the web   Networking   How the Internet and web work   Copyright, privacy, security, etc..   Current developments in the world of computers and the Internet

Software used for this course "Microsoft Office"   Microsoft Office will include following software:   Microsoft Word (word processing: newsletters, reports, etc..)   Power Point used for presentations   Excel used for Spreadsheets and Simple databases Web browsers:   Safari, Firefox, Internet Explorer or Netscape Adobe Photoshop and Image Ready:   multimedia, imaging and animation Macromedia Dreamweaver:   An HTML Editor used for web development (note that all software is listed without version references)

Notes about the text selection There are many other books that cover the same topics, and you are welcome to explore other computer books. In addition, there are many tutorials and resources on-line for learning about computers and software. We will post links to many on-line resources during the semester. Please feel free to let us know of sites that contain information and examples which you think would be of benefit to all of the students.

Assignments There will be nine assignments. Homework is 50% of your grade Be prepared to spend hrs per week to work on assignments. It is important not to get behind in turning in assignments. If you do get behind, we still want you to do the assignment, so it is better to turn in a late assignment than to skip it. However, late assignments will be severely penalized, and may not be graded except to note that the assignment was turned in. Assignments that you turn in MUST be your own work. It is fine to talk to other students about the assignments, but you MUST hand in your own work. Cheating will NOT be tolerated!

A Word About Cheating For the purposes of this class, cheating is defined as: For the purposes of this class, cheating is defined as:  Copying all or part of another student's homework, project or exam.  Allowing another student to copy all or part of your homework, project, or exam.  Discussing homework concepts is fine, but you must submit your own work If you are caught cheating, you will receive an immediate FAILURE for the course.
