Afterwards, design algorithms are presented for different types of tools as well as

An objective of the proposed on-line course is, as it has been pointed out, the comprehension of the creative design, on the Internet. Therefore, at the beginning, the designing of algorithms for each type of cutting tool is presented. This makes it possible to achieve the level of knowledge required in this area. The next steps are the study of creative techniques adapted to the Internet, ways of working in groups and, finally, team design,

Regarding the assessment (for the presented case), complex online tests are used and gradually developed. After the bibliography and the specific materials (course) are completed and after reaching a certain level of competence, the E-learning system allows the formation of working groups with the participation of a professor, in order to design cutting

The testing method provides a good balance between the objectives, their qualities and the time required for development. It also provides a high level of objectivity and repeatability. A test sample used in the chapter on turning tools is given below, where knowledge is gradually targeted. The students identify at first the principles of operation and the construction of various parts of the turning tools. Only afterwards does he discover the

In order to develop complex tests with powerful imagery, the "Quizmaker" software was used. The program provides twenty kinds of questions with which tests can be built. These include dual-choice items, completion items, multiple choice items, etc. A picture, sound or video can be added to each question. Also, the score may vary from one question to another,

It is impossible to skip a question without giving an answer. It is possible to limit the time

You can choose to complete the test multiple times (as allowed by the creators of the test), and every time you start the answers will come in a different order. At the end of the test, the student can get a message informing him or her if he has passed. In the end he or she

The notion of a tutorial emerged together with the development of IT technologies.

The tutorial is a tool often used nowadays in various fields in order to present a specific software product or business activities-products of a given company, etc. In making a tutorial there are several concepts to be taken into account, such as:


The user has the option of creating material-support improving message and audience impact. Tutorials are used in different situations:


The presentations are integrated with the Office software systems, being aligned with the principles of interaction and with the available instruments. They are geared towards solving the problems of communication and ensuring the possibility of personalization by

Multimedia is everything you can hear or see: texts, books, pictures, music, sounds, CDs, videos, DVDs, Records, Films, and more. Multimedia comes in many different formats. On the Internet you will find many of these elements embedded in web pages, and today's web browsers have support for a number of multimedia formats. The support for sounds, animations and videos is handled in different ways by different browsers. Some elements can be handled inline, some requires a plug-in and some requires an Active control. Multimedia elements (like sounds or videos) are stored in media files. The most common way to discover the media type is to look at the file extension. When a browser sees the file extensions .htm or .html, it will assume that the file is an HTML page. The .xml extension

Picture formats are recognized by extensions like .gif and .jpg. Multimedia elements also

The WAVE (waveform) format is developed by IBM and Microsoft. It is supported by all computers running Windows, and by all the most popular web browsers. Sounds stored in

MP3 files are actually MPEG files. But the MPEG format was originally developed for video by the Moving Pictures Experts Group. We can say that MP3 files are the sound part of the MPEG video format. MP3 is one of the most popular sound formats for music recording. The MP3 encoding system combines good compression (small files) with high quality. Expect all your future software systems to support it. Sounds stored in the MP3 format have the extension .mp3, or .mpga (for MPG Audio). The AIFF (Audio Interchange File Format) was developed by Apple. AIFF files are not cross-platform and the format is not supported

by all web browsers. Sounds stored in the AIFF format have the extension .aif or .aiff.

The AVI (Audio Video Interleave) format was developed by Microsoft. The AVI format is supported by all computers running Windows, and by all the most popular web browsers. It is a very common format on the Internet, but not always possible to play on non-Windows

Microsoft develops the Windows Media format. Windows Media is a common format on the Internet, but Windows Media movies cannot be played on non-Windows computer without an extra (free) component installed. Some later Windows Media movies cannot play at all on non-Windows computers because no player is available. Videos stored in the Windows

including elements of interactivity with the receiver user. The development of several versions for each application leads to the diversification of methods, which range from a simple slideshow to rich multimedia applications.

The tutorial aims to introduce participants to the educational process in a given subject, with the final goal of assimilating a minimum level of knowledge. But there are some fundamental differences from other educational processes:

Educational methodology is rich in media content (static content, motion screenshots, animation or video instructions), which is necessary in order to exemplify the necessary steps in solving the problem.
