  2. The role of multimedia in the practical aspects of instruction The use of multimedia for educational purposes not only opens new channels of utilization, but established the foundation for achieving an educational efficiency substantially surpassing the earlier rate. EVALUATION OF MULTIMEDIA PRODUCTS

  3. I. THE COMPOSITION OF THE MESSAGE The purpose of the message is addressing the user target group. Increase the value of the multimedia product: • Simple, short sentences, • Familiar terms and expressions, • Explanation of professional terminology

  4. II. SYSTEM-ORIENTED THINKING • This criteria system emphasizes the given program’s capability of meeting the set objectives, its ability to meet individual user demands, and the quality of media analysis. • Also, such issues have to be addressed as the program’s ability to accomodate differing learning techniques, its adaptability to individual and group use in addition to the quantifiability of the learned concepts.

  5. III. STRUCTURE In a multimedia production the following structured arrangement has to be recognizable: • introductory or lead-in image and sound, • greetings, main menu, • minor points (modules), • educational modules and nodes. The programs should also include a help option in addition to enabling the user to leave the program or to interrupt it.

  6. IV. NAVIGATION Navigation capability, a feature definitely to be included, enables the user to move forward and backward and display the actual function in order to avoid the feeling of being lost in the multimedia system.

  7. V. COMMUNICATION, INTERACTION We define interactivity as the option and experience of user interference. Interactivity indicates a concrete, real-time simultaneous interaction in the human-machine relationship. The program must include the devices and markings (tools and icons) facilitating communication

  8. VI. PEDAGOGICAL DIDACTIC CRITERIA A good multimedia program enables the student to process the materials at an optimal rate and rhythm. During the application the learner can prepare notes, intensifying the processing thereby making the communication truly multimedial involving more sensory organs.

  9. VII. PSYCHOLOGICAL, ERGONOMIC CRITERIA The quality of the user surface depends on: • The number and type of colors used, • the definition and clarity of the graphic units, • readibility The short lines and dual spacing used in page setting are ideal. Furthermore, the consistent arrangement of the individual pages, whether projecting a harmonic or discordant appearance is essential.

  10. VIII.THE VISUAL AND AUDITIVE CRITERIA OF MULTIMEDIA COMPONENTS Meeting the demands of media-based message transmission

  11. Exit THE VISUAL AND AUDITIVE CRITERIA OF MULTIMEDIA COMPONENTS 1. Textual elements Text can facilitate a better understanding of picture images especially when pictures and commentary are insufficient. In multimedia the text can appear as information, as navigatory assistance and as an aesthetic component.

  12. THE VISUAL AND AUDITIVE CRITERIA OF MULTIMEDIA COMPONENTS 2. Numbers, Data Bases Modern multimedia provide a large amount of information for the user as in addition to text numbers and data can function as components.

  13. THE VISUAL AND AUDITIVE CRITERIA OF MULTIMEDIA COMPONENTS 3. Freeze frames Expectations: • The quality of composition, • the adherence to the principle of deliberate color selection, • the discernibility of figures and the background, • the harmonious grouping and arrangement, • the employment of the proper methods of picture image emphasis.

  14. THE VISUAL AND AUDITIVE CRITERIA OF MULTIMEDIA COMPONENTS 4. Icons, symbols, logos • The simplicity and intelligibility of production, • the intensity of highlighting the essence of the message, • the utilization of adequate elements increase the efficiency of multimedia.

  15. THE VISUAL AND AUDITIVE CRITERIA OF MULTIMEDIA COMPONENTS 5. 3D displays • Important evaluation criteria include the spatial complexity and spatial display (stereoscopic display) amd spatial texture of the module body and the selection of illumination.

  16. THE VISUAL AND AUDITIVE CRITERIA OF MULTIMEDIA COMPONENTS 5. Animation The term means the bringing of pictures to life. Evaluation criteria should include: • The justification of the application, • the continuity (steady movement), • the attempt at making movement imitating reality, • dynamics (fast, balanced, slow) • the product’s capability of calling attention to itself.

  17. THE VISUAL AND AUDITIVE CRITERIA OF MULTIMEDIA COMPONENTS Exit 7. Active surfaces Expectations: • The simplicity of components, • the interference capability, • the answerability, • the degree of the difficulty of the acquisition of user proficiency The crucial action buttons are: • to the start, back, home, forward, end, reverse, and exit (escape).

  18. THE VISUAL AND AUDITIVE CRITERIA OF MULTIMEDIA COMPONENTS 8. Auditive information Sound effects could also take the form of a: • whisper, • scream, • howl, • animal sounds, • pleasant music, • special effect, • background with some dramatic atmosphere.

  19. THE VISUAL AND AUDITIVE CRITERIA OF MULTIMEDIA COMPONENTS 9. Moving picture images The use of video is recommended if the former carries more information than the freeze frame photograph and is especially suitable for the demonstration of such phenomena which become intelligible or understandable in their course or display the space in a panoramic movement.

  20. THE VISUAL AND AUDITIVE CRITERIA OF MULTIMEDIA COMPONENTS Moving picture images • The size of the picture, movement, illumination and the right selection of color are especially important. The movement of the camera has to be steady and instead of long settings short, dynamic, commercial-like information or nodes should be used. • Style conflict

  21. IX. TECHNICAL ASPECTS OF CONSTRUCTION Expectations: • proper selection of faultless source materials, • adequate processing and display efforts. Mistakes: • Cropping • Synchronization • Camera moving

  22. X. COMPLEMENTARY ELEMENTS These are the elements the user encounters first. Expectations: • Both graphically and installation wise the product would meet the user’s expectations. • Instructions in a form of a printed supplement or support materials demonstrating educational methodology.

  23. XI. ON-LINE UPDATING The user-friendly service package contains: • Telephone help lines, • on-line information transmission, • on-line or offline updating capabilities.

  24. XII. SUBJECTIVE EVALUATION ?
