AUDIO-VISUAL AIDS

122 Audio-visual aids are used especially:

a) as resources for enriching catechetical instruction with objective elements; for this use, they should excel in truthfulness, careful selection of ideas, and pedagogical clarity; and

b) as images for properly cultivating the powers of the senses and the imagination; for this use they should have real beauty and be effective in moving people.

In regard to these aids, the following are necessary functions:

—fostering studies concerning the criteria which should guide the production and selection of these aids in keeping with the particular aspects of the Christian message that are to be presented and the particular groups of people for whom they are intended; and

—.instructing catechists in a right use of these aids (it often happens that catechists are ignorant of the proper nature of visual language; if happens more often that audio-visual aids used improperly lead to passive rather than active behavior; and so on).
