Audiovisual teaching and training device For the use of carrier cards with optical, acoustic and mechanical information (according to DBGM file number G 74 01 214 »9)

The aim of the invention is an audiovisual aid for the general teaching and especially for the therapy of dyslexics, which at the same time the properties owns a "teaching machine".

If audiovisual aids are based on the knowledge of If learning research is to be used appropriately, it must meet the following requirements:

a) Optical and acoustic information must be presented,

b) the learning process must be broken down into individual small steps. The learning steps have changed as desired and can be repeated.

c) It must be possible to immediately set exercises for each learning session, through which what has been learned is memorized and tested.

d) The student must immediately know whether his solution was correct .

For requirement (c) one generally uses the multiple choice procedure, in which different answers are proposed to a question, only one of which is correct. Have the student identify the correct answer.

This means that the correct answer to each test question is "recognized" by the device maä.

7842189-H74

The information required for this must be entered separately into the device in each exercise step.

The previously known audiovisual systems mostly meet only requirement (a) (e.g. sound film, video tape, video disc), in some cases also requirement (c) (exercises with given answers)

A common arrangement is that slides are shown together with a tape and that the Slide change is controlled from the tape. With a stereo tape and additional equipment, this system may be able to do exercises put »The content and sequence of the learning steps are always fixed and cannot be tailored to the needs of the individual The student (requirement b).

In addition, the following difficulty arises: If the pupil has to repeat a learning step and rewinds the tape for this purpose, land and diary can get out of step and have to be synchronized again by additional meows.

The commissioning of such a system proves difficult if technically inexperienced laypeople, e.g. teachers, are supposed to handle it.

Any repeatability and (sometimes) variability of the learning programs is achieved by conventional teaching machines with or without computer support. Apart from the fact that the latter are very expensive, the valuable combination of acoustic and optical communication of information must be dispensed with in any case (requirement a). In addition, there are applications because the "bestowed on acoustic information because" the teaching objective in question: Se sB in the therapy of dyslexics.

The invention was therefore based on the following object

7141 Ht-

1) To find a carrier form in which optical and acoustic information can be stored at the same time, which "but allows any changes and repetitions of the program without the synchronicity of the information being disturbed."

2) In addition, the carrier had to provide the possibility of influencing the status of the associated device after each individual program or learning step from the data carrier through further stored information (exercises with predefined answers) *

3) Construct a device in the disk after Points 1 and 2 can be used and the operation of which can be left to students if possible

4) To keep the carrier and device as cheap as possible so that the intended educational use, e.g. in schools, can be realized

The task "is inventively solved by the fact that information is mnero te * r ten- shaped deceptions in three modern ways? is saved.

The card also contains the information in the form of the stables , which are evaluated mechanically or electrically,

by which the device is brought into certain states, indicators for

pure sound cards,

Face cards and

Exercise cards

and finally a margin hole field, which makes it easier for the teacher to sort the cards.

The associated teaching device essentially contains three components, which are housed together in one housing:

Card part : This is a memory in which the cards are stacked in the previously determined program sequence optical evaluation is accessible.

In this position, as on the transport route, the punched information is accessible.

Finally, the transport device ejects the card, which is collected outside the device

Information section : This includes the devices that allow access to the stored information: sound head with amplifier and loudspeaker, mechanical or optoelectronic devices for scanning the punched points, lighting or projection devices for the optical information

Control : The devices that are used to influence the processes in the map section and in the information section: external operating elements, device-internal information processing, timing, choice of device states, tachistoscopic devices.

The invention is described below with reference to the drawings Fig. 1 to Fig. 4 explained in more detail.

The carrier card (Fig. 1) is preferably 1/4 A4 in size, so 21 χ 7 »5 cm. The arrow (9) indicates the direction of movement of the card in the device.

The image field (i) takes up most of the map area one, it is printed, written on by hand or prepared photographically. If the card is used for projection, then Clear plastic material to be preferred, otherwise white.

The sound tracks (2) and (3) run in the longitudinal direction; she are scanned one after the other and provide the specified dimensions and a transport speed of 4 cm / s approx. 10 seconds acoustic signal per card »

The card can be marked by punching in predetermined places:

A punch (hole) at (4) identifies picture cards which are defined in that they are automatically ejected from the device after a certain viewing time. The length of the viewing time can be predetermined using the punchings in field (5).

A punch at (6) identifies sound cards that do not have a picture but are used, for example, after picture cards if their soundtrack is not sufficient for the acoustic text.

Sound cards take a different route in the device and are not visible.

If there is no punching in either (4) or (6), the card is considered an exercise card . It remains visible in the device until the student presses an answer button. In this case, the punchings in field (7) are used to decide whether the answer is correct.

Since sound and picture cards are handled differently in the device, the sequence of the Cards changed · That is why all cards are provided with a margin hole field (8) in which the number of each card is binary-decadic is encrypted. In this way, the original sequence can be restored in a few simple steps.

The apparatus in which the carrier card is used is shown in elevation in FIG. Fig. 3 gives the section A-B.

The stack of cards is inserted into the memory (10). After Pressing the button (14) the card runs through the device and is visible in the viewing window (11) at the point (15).

If it is an exercise card, it will be run in A timer is triggered on the card, which makes the card visible for a specific, adjustable period of time otherwise they are covered by a semi-transparent mirror (16) is. This tachistoscopic facility only comes into effect with exercise cards and can of course be switched off will.

The student chooses one of the given answers and reacts with the help of the buttons (12). If his answer is correct, "GOOD" (17) lights up and a buzzer sounds. If very small or severely disturbed children are supposed to work on the device, the immediate reward is the issue of a candy.In any case, the card is ejected after the student's first session.The button (13) causes the last card in the device to expire .

Fig. 4 shows schematically the path of the card inside the device, which is from the stack (10) on the two audio heads (19) and (20) leads past to a switch (21) at which the sound cards run out of the device on the way (22) while the picture and exercise cards come to the point (15) where they are visible. The logical decision about the The time sequence of these functions and the path that the card takes falls at the contact points (18) that form the edge of the card and query the punchings in the card.

The system described combines the advantages of the audiovisual teaching method with those of a conventional one Teaching machine.
