DE19803874C2 - Audiovisual learning, testing and quiz device - Google Patents

Description

The invention relates to an audiovisual device for imparting, learning or checking knowledge or teaching material and conducting quizzes or intelligence tests according to Preamble of claim 1, wherein the device for both at home Acquisition and review of knowledge as well as in school Teaching mediation, for example with questions coordinated with textbooks, or about Conducting exams can be used.

Such a device is known from the document DE 33 32 869 A1. On one The screen shows a question with several answer options, the user try to find the correct answer. The questions and answers are in stored in a memory. The disadvantage of this device is that it does not have multiple operating modes, For example, demonstrating questions and answers, learning tasks and checking of questions. It practically only works in exam mode - the user can after an incorrect answer, do not display the correct solution as it does in a Learning mode would be possible. Nor does it have a demonstration mode in which practically first of all to impart knowledge, explaining the question with its correct answer is demonstrated.

In DE 27 25 298 A1 an exercise device is described in which the to a task correct answer in a response field, which consists of 20 electrically separated ones Contact areas exist, must be found. Here are the results in the correct order in several electronic read-only memories so that the correct ones Answers differ in order from task set to task set. A Free assignment of self-created questions to their answers is not possible.

DE 29 26 420 C2 deals with a question / answer game in which a question from one sheet selected and a numerical coding assigned to this question on a keyboard is entered. Then the coding of a selected answer is also made entered and a comparator determines whether the stored assignment of the Question encoding to encode the correct answer was right or wrong, d. H. the question was answered correctly or incorrectly.

DE 32 01 305 A1 also contains a learning / test device based on the question / answer principle, where only exam questions are asked and a number of answers to each question Tobe offered. Here, too, the user must select his answer by entering it a coding.  

The content of DE 44 04 649 A1 is a technical training and demonstration system using a PC with a separate monitor, keyboard and mouse, which as Operating modes the presentation of a longer document to get to know the working method of the user program, demonstration of a specific operation and execution of the user program.

US 5 618 182 includes a computer-based learning method by use a computer to improve the performance of the user in multiple choice tests. Here a standard PC (desktop or notebook) with the operating system DOS, WINDOWS, OS / 2 or UNIX are used.

US 5 228 859 describes as an exercise system a device for a computer with which an audio output is looped through an additional memory with two data buffers, that the central processor unit remains free to continue to be independent To be able to edit computer programs on the PC. The digital data storage media, such as cassettes or CDs, can be created by the user in edit mode or in Play mode where the learner hears the lesson and sees it on the screen be played.

WO 9101540 A1 represents a software method for one or two students to teach using a standard computer. This includes Tutorial questions with a set of multiple choice answers of different Levels of difficulty. Various evaluations are made during the course of the program performed.

The known learning devices or learning systems do not allow the same questions and Answer offers either in a demonstration mode (correct answer is demonstrated), Learning mode, (correct answer can be found by trying) and / or Exam mode (correct answer must be given) and a preliminary and Allow or prohibit turning back of questions.

The invention has therefore set itself the task of a handy, with a calculator comparable and usable independently of a PC, above all light, that is, to create an intuitively operable device that has four operating modes, the demonstration mode, the learning mode, the exam mode and the intelligence test mode, so that in Demonstration mode through questions and explanatory answers Knowledge can be conveyed in the Learning mode active by asking questions and trying to find the right answer  Learning takes place and in the examination mode by asking questions and once giving the information correct answer the knowledge acquired can be checked.

This, the object underlying the invention is achieved by designing according to Characteristic of claim 1 solved. Further advantageous configurations are the Removable subclaims.

The object is achieved in that using a CPU and further, partially modified and dismantled, characteristic assemblies of a PC the questions and their associated answer offers in a memory module with additional Attributes are stored so that only the questions and associated answers are on the display appear, whose attribute corresponds to the operating mode switched on on the learning device men, that is, the program stored in the memory module compares the switch position of the Operating mode switch with the attributes of the question.

The advantages achieved with the invention are in particular that, for example, a Question with the associated answer offers can have one or more attributes, so that it can be called up in only one or in several operating modes.

The learning device works in particular independently of a PC - the memory module the questions and answers, point weightings, time limits and operating mode attributes created separately on a PC. As a result, the learning device only has a display and some clearly arranged controls. The memory modules can be a ROM, EPROM, EEPROM or the like Storage media included that can only be read out or read out and are rewritable. When using rewritable memory modules, for example conventional photo memory cards from digital cameras or normal floppy disks, there is also the possibility to use the answers given in the exam mode for the purpose save an evaluation.

The programming of the memory module, that is, asking the questions with the associated attributes and response offers may be from the supplier, for example associated textbooks, or by the user using a PC and associated software, if necessary via an adapter to hold the module. For checking or testing of the programmed memory module, the device can be simulated on the PC, i.e. the Structure can be mapped so that the corresponding buttons and buttons are displayed at the click of a mouse Switch operated, comparable to the simulation of a calculator on a  PC. This means that even computer users who do not have a learning device can use the Answer questions like with the learning device.

With textbooks, a memory module can be used for each or several chapters corresponding questions and answers with different attributes become.

The memory modules can be copied by the user using a PC Deviation from the usual disk format of the above. Adapter is used.

For example, a corresponding module from Examiners themselves, in which case all questions only the examiner Get attribute. In addition, each question may have a time limit to answer it be provided. The test mode must be carried out on the device in order to carry out the test be set. In a control / result display field, the number of correct answered questions compared to the total number of questions. One can Point evaluation and percentage evaluation take place.

The four operating modes can preferably be found on the back of the device adjust the attached switch. A button can also be used instead of the switch which are cycled through the operating modes, with the display of the active mode in an information display field.

Via a printer port, which is also preferably attached to the back, through A hard copy is carried out at any time at the push of a button, i.e. the entire content of all Display fields or parts of the monitor can be printed out, creating another Possibility to evaluate exams.

The questions and answers can be asked through text or graphics, voice, or sound output or film sequences are presented. This allows verbal, musical or film-technical questions and answers can be realized.

The previously mentioned examination mode also serves to carry out quiz-like questions. / Answer games, since there is no difference to an examination procedure. In the Quiz games very often involve two players, one against the other other plays. To implement this application variant, the device has the Front two sockets for connecting two small control panels with corresponding Keys to answer questions. By inserting these control panels for the Both players will override the device's original answer buttons and  the device switches to quiz mode. The points scored are separated for each player output in the operating / result display field.

Another operating mode of the device is the intelligence test mode. Here, the Questions with the associated answer offers displayed or played back that the Have intelligence test attribute. Only one answer is correct, with a follow-up question after given answer or a time limit. Internally there is an evaluation and after After running through all questions, an IQ value determined using known methods is displayed. The invention will be explained below using an exemplary embodiment.

As can be seen from FIG. 1, all operating and display elements are accommodated in an individually configurable housing 1 . The device is switched on with the on / off switch 2 , which is combined with a control LED 3 to indicate the correct power supply. The power supply takes place via built-in rechargeable batteries and / or, as shown in FIG. 2, via a power supply unit which can be connected to the power socket 4 and which simultaneously recharges the rechargeable batteries. After switching on, the usual loading of the BIOS and the operating system takes place from the ROM, after which the readiness for operation is communicated with a corresponding output in the operating / result display field 5 . If there is still no memory module 6 in the memory module receptacle 7 (see side view shown in FIG. 4), the output could be: "OK <insert memory module". If a memory module is already inserted, the message "OK <press start button" may appear. If the memory module 6 is a normal floppy disk, the memory module holder 7 is a floppy disk drive. The first task is called up from the memory module with the Start / New button 8 . This button can be pressed at any time during the demonstration, learning, exam / quiz or intelligence test process - the task cycle of the tasks in the memory module is restarted with the corresponding attribute, whereby points already collected or other evaluations are reset. Preferably on the back of the device, see Fig. 2, the operating mode switch 9 is attached. The set operating mode is permanently displayed on the information display field 10 . The operating mode switch can be designed as a slide switch with labeling of the switch positions or as a button for cyclical selection of the operating mode according to the display. In addition to the operating mode display, further information on the inserted memory module, such as module name, manufacturer, creation date and number of questions with the set operating mode attribute, can appear in the information display field 10 as a status display.

The task in the form of a text output, a still picture or a film sequence takes place in task field 11 , with speech or sound output additionally being possible via a built-in loudspeaker. In the five answer fields 12 with the associated selection buttons 13 , which have the designations a to e for the clear assignment of tasks and solutions from teaching materials, the answer offers are also displayed in the form of teen or still pictures or played as film sequences, here after pressing a button e to a sound output is also possible.

If the button belonging to the correct answer has been pressed, a green frame appears in the corresponding answer field; answer fields with incorrect solutions are given a red frame after pressing the corresponding button. The demonstration mode is an exception; the correct answer is immediately framed in green. Instead of the illuminated frames in the answer fields, for example, a two-color LED in transparent caps of the selection buttons 13 could also be used to indicate the correct or incorrect answer.

The device can also have a built-in microphone, so that, for example, to a Text response to learn a foreign language via a speech recognition comparison Pronunciation of the text response can be checked.

With the forward button 14 and back button 15 , the tasks set in the demonstration mode and learning mode can be browsed back and forth with the associated solution offers. In test / quiz mode and intelligence test mode, these buttons, which are expediently designed in a triangular shape, are ineffective.

With the print button 16 , a PC-typical hardcopy printout can take place, that is, the entire content of all display fields or only the operating / result display field 5 and the information display field 10 at the time of the key press is via the parallel Centronics printer interface 17 printed out.

The display fields 5 , 10 , 11 and 12 can consist of separate displays, for example in the LCD version, partially combined displays or a continuous display, the optical separation of the fields being taken over by the display itself or housing parts.

When processing quiz questions for two people A and B as opponents, as shown in FIG. 3, two small control panels 19 , which likewise have the answer buttons a to e, can be connected via the sockets 18 . The operating mode switch 9 must be in the test position for quizzes. The tasks and solutions are provided in the corresponding fields 11 and 12 as well as when operated by one person. The device should therefore be set up so that both quiz players can easily see the task with the solutions. The player who first types in the correct answer on his control panel receives one or more points for weighted questions. The points achieved are shown for each player in the control / result display field 5 .

Fig. 5 shows the block diagram of the combined learning, testing and intelligence testing device comprising the following assemblies:

The following are connected to the system bus 20 , consisting of the address bus 21 , the data bus 22 and the control bus 23 :

• the microprocessor 24 ,
• the RAM 25 , that is to say the read-write memory,
• - the BIOS ROM 26 ,
• - The video interface 27 for display 28 , on which the operating / result display field 5 , the information display field 10 , the task field 11 and the response fields 12 are shown, and
• - The input and output plant 29 .

The input and output mechanism 29 enables the connection:

• - the user interface 30 for the start / new button 8 , the selection button 13 , the forward button 14 , the back button 15 , the print button 16 and the connection of the two control panels 19 ,
• - the operating mode switch 9 ,
• - The printer interface 17 for connecting a printer 31 , and
• - The memory module holder 7 for holding the memory module 6 .

Fig. 11 shows a programming sheet in the form of a table. According to such a table, the memory module with the questions and answers is created using a PC and associated software. Each line forms a record for a question with its five answer offers. In addition to the question and the answers, the attributes, point weighting and time limit for each question are entered in this table. Questions and answers are enclosed in quotation marks. Graphics / images, e.g. B. in bmp format, video sequences, e.g. B. in avi format, and / or sound, z. B. be added in mid format. The data records can of course also be entered via a data mask with the associated data fields, which is common in database systems. The operating sequence and the possibilities of the device for each adjustable operating mode are described in more detail below using examples from the programming sheet according to FIG. 11.

Demonstration mode: Fig. 6 shows an example in the demonstration mode. The operating mode switch is in the Show (V) position, therefore only the questions from the memory module 6 that have the demonstration attribute are asked or played in task field 11 , here the 3rd question with the V attribute. The correct solution appears framed in green in one of the answer fields 12 , the remaining answer fields show incorrect answers, which are described in such a way that they might appear correct at first glance when reading or looking at them and should thus encourage reflection. After pressing the pre-button 14 , the next question appears with its answer offers. In the demonstration mode, the forward and back buttons 14 and 15 can be used to page forward or backward through the questions and associated answers. A point evaluation in the operating / result display field 5 is not provided.

Learning mode: FIG. 7 shows an example in the learning mode. The operating mode switch is in the learning position (L), which means that only the questions from the memory module 6 that have the learning attribute are asked or played in the task field 11 , here the third question with the L attribute. In the answer fields 12 five answer offers appear, whereby only one answer is correct. The correct answer, the answer field of which appears framed in green, can be found out by pressing the associated push buttons 13 . If the correct solution has been found, the next question may be asked, possibly with a time delay to read the answer again. In the learning mode as well as in the demonstration mode, the forward and back facts 14 and 15 are effective. A point evaluation in the operating / result display field 5 is also not provided here.

Exam / Quiz Mode: Fig. 8 shows an example in the exam mode. The operating mode switch is in the Exam / Quiz (P / Q) position, which means that only the questions that have the exam attribute are removed from the memory module. In the answer fields 12 , five solutions are offered, of which, as in the learning mode, only one is correct, which, however, now has to be specified with just one push of the associated push button 13 . The correctly specified solution appears in a green frame again, wrong answers are framed in red. After pressing the button or the time limit to answer a question has been exceeded, the next task is presented. In the exam / quiz mode, buttons 14 and 15 are ineffective for scrolling the tasks back and forth. During the test process, the operating / result display field 5 always shows how many questions have been answered correctly or incorrectly so far, how many points have been achieved so far and what percentage this corresponds to.

If the device is used as a quiz game device for two opponents A and B, that is to say that the two control panels 19 are plugged in, only the questions with the examination attribute are played here. A corresponding example is shown in FIG. 9. On the basis of the inserted control panels, the device recognizes that the test questions are being used for a quiz game and makes the associated modifications in the information field 10 and control / result display field 5 . The points that belong to the question are added to the player who answered the question first on his control panel. Each player has only one attempt. The next question is displayed after one of the players answered the question correctly, after both players answered the question incorrectly, or after a time limit. In the operating / result display field 5 , a punctual evaluation is carried out for each player during the game.

Intelligence test mode: Fig. 10 shows an example of performing an intelligence test. The operating mode switch is in the intelligence test (IQ) position, which means that only the questions with the intelligence test attribute are removed from the memory module. The correct answer must be found by pressing a button, whereby the correct solution appears framed in green for a short time, wrong answers are framed in red. After pressing the button or the time limit has expired, the next task appears. The forward / reverse buttons 14 and 15 are ineffective in the intelligence test mode. Even during the intelligence test, the operating / result display field 5 shows after each question how many questions have been answered correctly or incorrectly. After all intelligence test questions have been run through, the software determines the intelligence quotient and outputs it in operating / result display field 5 .

In all operating modes, the following messages are displayed in the information display field 10 :

• - Information about the memory module (name, manufacturer, date of creation)
• - the set operating mode, and
• - the number of total tasks that will appear in the set operating mode.
