Description

[Detailed Description of the Invention] The present invention relates to improving the functions of a group learning device.

BACKGROUND ART Group learning devices, such as language practice devices and music practice devices, have been known in the past, in which a plurality of study tables for students are provided for one adjustment console for the teacher. In conventional group learning devices of this type, for example, language practice devices for learning English conversation, several types of teaching material signals are supplied from a control console to each learning desk, and students listen to these teaching material signals through headphones or at the learning desk. I try to learn English conversation by repeatedly recording and playing back the tape recorder installed in the school.
Conventional devices have a method in which the teacher selects teaching materials according to each student's ability from among several types of teaching materials;
There were two methods: one was to send all teaching materials from the adjustment desk to all study desks, and the other was for students to select the teaching materials that suited them. However, when teaching English conversation classes, it is more practical to decide on a case-by-case basis whether the teacher or the students should select several types of teaching materials.

The present invention was developed based on this idea, and embodiments of the present invention will be described below with reference to the drawings.

Figure 1 shows the circuit installed in the adjustment console, and the second
The figure shows the circuits provided at each study desk. In this implementation, the teacher or student can select from four types of teaching materials numbered 1 to 4, and if the teacher makes a selection, the teaching material selected by the teacher will be sent preferentially regardless of the student's selection. It is something.

In FIG. 1, the adjustment console is equipped with four tape recorders ₁₁ to ₁₄ for respectively playing back tapes on which four types of teaching materials are recorded. The teaching material signals _A1 to _A4 reproduced by these tape recorders ₁₁ to ₁₄ are supplied to n study desks from output terminals ₂₁ to ₂₄ , respectively. In addition, there are four teacher teaching material selection switches S ₁ to S ₄ and n study desk selection switches S _S1.
~S _So are provided, and n teaching material number memory memories 3 ₁ to 3 _o are provided. When storing teaching material numbers in these memories 3 ₁ to 3 _o ,
First, while closing switch S _S1 , switch S ₁ to _{S 4}
Select one of them and close it. As a result, the teaching material number to be sent to the first study desk is stored in the memory ₃₁ . The memory ₃₁ is immediately read out and a "1" (high level) signal appears at one of its output terminals ₄₁₁ to ₄₁₄ . For example, when the No. 1 teaching material is selected, the output terminal 4 ₁₁ becomes "1", and the other output terminals 4 ₁₁ , 4 ₁₂ , 4 ₁₄ become "0" (low level).
Next, the same operation as above is performed for each of the switches S _S2 to S _So to store the teaching material numbers in the memories 3 ₂ to 3 _o , respectively. Note that when the student selects a teaching material, the above operation is not performed and the information in the memory becomes "0". Therefore, all four output terminals of the memory are "0"
becomes.

Figure 2 shows a circuit installed in one study desk, and the above-mentioned reproduced teaching material signal A ₁ is input to the input terminals 5 ₁ to 5 ₄ .
~A ₄ is added. Further, a signal of "1" is applied to the input terminal among the input terminals 6 ₁ to 6 ₄ corresponding to the teaching material number selected for this study desk. For example, if this study desk is the first study table and the first teaching material is selected, output terminal 4 ₁₁ in Figure 1
A signal of "1" is added to input terminal ₆₁ from
A “0” signal is applied to the other input terminals 6 ₂ , 6 ₃ , 6 ₄ . The signals of the input terminals 6 ₁ to 6 ₄ are applied to the OR gate 7 and also to the NOR gates 8 ₁ to 8
is applied to one input terminal of ₄ . In addition, four switches S _P1 to S _P4 are provided for students to select teaching materials, and one contact point of these switches S _P1 to S _P4 is connected in common, and the output of the OR gate 7 is connected to this connection point. A signal inverted by an inverter 12 is applied. At the same time, the other contacts are connected to the other input terminals of the NOR gates 8 ₁ to 8 ₄ , respectively. The teaching material signals A ₁ to _{A 4} above are switch circuits 9 ₁
~9 is added to amplifier 10 via ₄ , and amplifier 1
The zero output is applied to headphone 11. The switch circuits 9 ₁ to 9 ₄ are opened and closed based on the outputs of the NOR gates 8 ₁ to 8 ₄ .

In the above configuration, it is assumed that a signal of "1" is now being applied to the input terminal ₆₁ . Note that teaching material signals A ₁ to A ₄ are applied to the input terminals 5 ₁ to 5 ₄ . In this case, the output of the OR gate 7 is "1" and the output of the inverter 12 is "0", so the switches S _P1 to S _P4 are independent of their open/closed states, and one input of the NOR gates 8 ₁ to 8 ₄ is It becomes "0".
That is, in this state, the switches S _P1 to _{S P4} are in a disabled state, and the mode is set in which the teacher selects the teaching material. Then, the "1" signal applied to the input terminal ₆₁ is applied to the NOR gate ₈₁ , whereby a "0" signal is obtained from the NOR gate ₈₁ , and this signal closes the switch circuit _91. .
As a result, the teaching material signal _A1 is applied to the headphone 11 through the switch circuit ₉₁ and the amplifier 10. At this time, since the inputs of the other NOR gates 8 ₂ , 8 ₃ , 8 ₄ are all "0", their outputs are "1", so the switch circuits 9 ₂ , 9 ₃ , 9 ₄ are opened, and the teaching material signal A ₂ , A ₃ and A ₄ are blocked.

Next, when the teacher on the adjustment console side in Figure 1 allows the student at the first study desk to select the teaching material, all outputs from the output terminals ₄₁ to ₄₁₄ of the memory ₃₁ become "0", This “0” signal is input terminal 6 ₁ in Fig. 2.
~6 ₄ to or gate 7 and noah gate 8 ₁ ~8
₄ respectively. Therefore, the output of the inverter 12 becomes "1". Therefore, switches S _P1 to _{S P4}
If one of the gates is selectively closed, the above output "1" is sent to the Noah gate ₈ through this closed switch.
~8 Selectively added to one of ₄ . This sets the mode in which students select teaching materials. Next, for example, when the switch _SP1 is closed, the inputs of the NOR gate ₈₁ become "1" and "0", and the output becomes "0".
Therefore, switch circuit ₉₁ is closed and teaching material signal A is applied to headphone 11. At this time, since the inputs of the other NOR gates 8 ₂ , 8 ₃ , 8 ₄ are all "0", the output becomes "1", the switch circuits 9 ₂ , 9 ₃ , 9 ₄ are opened, and the teaching material signal is
A ₂ , A ₃ , and A ₄ are blocked. Furthermore, if the switch _SP1 is opened and the switch _SP2 is closed in this state, the output of the NOR gate ₈₂ becomes "0" and the switch circuit ₉₂ is closed, so that the educational material signal _A2 is applied to the headphone 11.

According to the above, both the teacher and the student can select four types of teaching materials, and if the teacher makes a selection, the teacher's selection is prioritized over the student's selection. Incidentally, on the adjustment console side, which teaching material is selected at each study console may be displayed using a number.

The present invention provides a group learning device that is equipped with a teacher's adjustment console and a plurality of student study tables, and in which a plurality of types of teaching material signals are supplied from the adjustment console to each of the study tables. Switch S ₁ ~ _{S 4}
, learning desk selection switches S _S1 to S _So , storage means 3 ₁ to 3 for storing the number of the teaching material selected by the teacher's teaching material selection switch and the number of the learning desk selected by the learning desk selection switch. _o is installed on the above adjustment desk, and a student teaching material selection switch S _P1 ~
S _Po and a priority setting circuit (Fig. 2) operated according to the student teaching material switch and the information read from the storage means are installed in the study desk, and the study desk number stored in the storage means is provided. On the study desk,
A group learning device characterized in that a teaching material with a teaching material number stored in correspondence with the learning desk number is supplied in priority to the operation of the student teaching material selection switch of the study desk. It is.

Therefore, according to the present invention, both the teacher and the students can select the teaching materials, so if the teacher or the students can select the teaching materials according to the learning situation, the range of learning methods will be expanded and the learning effect will be further improved. can be improved. Furthermore, since the teacher can select teaching materials preferentially, the teacher can take the initiative in learning and proceed with the learning. In addition, since the study desk is equipped with a priority setting circuit, if an arbitrary number of study desks can be connected to one adjustment console, the number of priority setting circuits will be higher than when the priority setting circuit is installed on the adjustment console. can eliminate waste.
