A teaching system apparatus and method for improving the ability of a student to learn with a connection to a remote computer. A plurality of CD Roms for storing at least one of text, audio and visual data are utilized on a local computer having memory. The local computer is in communication with the remote computer and the CD Roms are able to be loaded and operated on the local computer. A mechanism through software is provided on said CD Roms for causing the local computer to communicate with the remote computer and determine if the CD Roms are still up to date, and software on the CD Roms may request the local computer to download information from the remote computer. A mechanism via software on the CD Roms prevents local computer access of particular data on the CD Roms without an unlock code from the remote computer. |

DETAILED DESCRIPTION According to the present invention, there is provided an automated system of teaching and lesson management, which requires no classroom teachers. The system eliminates live instructors, while maintaining the quality of educational material by demanding the students or trainees to prove they have mastered and learned the taught material, by demanding such students to pass particular scored tests. The computerized learning environment includes the use of a local computer with a compact disk player such as a conventional CD Rom Drive, and memory. The local computer is connected to a computer network, through which communication signals (data including text, audio, and visual information) may be sent to and received from a centralized server computer. The system utilized multiple CD Rom disks or products to "front load" data intensive elements of the training program at the local computer site. Such data intensive elements include, without limitation, audio, video, multimedia, and other types of stored data that require comparatively large amounts of storage or memory space. Through communication through a computer network to another computer called a server, the software located on the CD Rom products, is able to determine the last date to which itself is current, and interrogate the server computer to determine if any updates are available. The local computer may then send a code to the server, instructing the server to check for any updates or additional information. If there are updates and data, the server will send the local computer such electronic updates and data via the communications network. The local computer will save such updates and data to its memory. The local computer through the use of software will determine what CD Rom material has been updated, and utilize only the updated material, not the outdated material, embedded within the CD Rom disks or products. A key importance of this system is that certain portions of the CD Rom teaching program are not student accessible until successfully passing a computerized test based on previously studied material stored on the CD Rom disk or in the computer memory
