Description

[Detailed Description of the Invention] The present invention relates to a teaching material sending device, which sends out each teaching material in three steps of conference, select one, and minus one from a tape recorder on which each teaching material is recorded in advance by just a simple switch operation. The purpose of the present invention is to provide a teaching material transmitting device that can transmit educational materials.

Conventionally, language learning devices, music learning devices, and the like have been known as group learning devices, and conversation learning has been effective in ensemble learning and the like.

For example, in conversation learning, students are first asked to listen to the entire conversation material so that they understand the entire conversation, then have the students listen to the material that only includes their own conversation to practice only their own conversation, and then have the students listen to the material that only includes their own conversation to practice only their own conversation. Have the students listen to the conversation materials and practice by adding their own conversations as a whole conversation. On the other hand, in ensemble learning, just like conversation learning, students are asked to listen to teaching materials for the entire ensemble and have them grasp it, then listen to teaching materials for only their own part and have them practice it, and then remove only their own parts. Have the students listen to the teaching material (Miyujitsuk Minus One) and practice as an ensemble by adding their own parts. In this way, in conversation learning, ensemble learning, etc., the above three steps are cycled through and teaching materials are repeatedly sent out.

By the way, with conventional devices used for such learning, one purchases commercially available tapes on which each teaching material corresponding to each of the three steps mentioned above is recorded, edits the tapes so that each teaching material is sent out in a series, and then edits the tapes. Alternatively, the above-mentioned commercially available tapes may be played back using respective tape recorders. For this reason, with conventional systems, it takes time to edit the tapes, which puts a heavy burden on teachers, and because they only play back commercially available tapes, the content is uniform and does not change. There were shortcomings such as not being able to achieve sufficient learning effects.

The present invention eliminates the above-mentioned drawbacks, and an embodiment thereof will be described below with reference to the drawings.

FIG. 1 shows a block system diagram of an embodiment of the teaching material delivery device according to the present invention. In the figure, S ₁ is a conference (or ensemble) switch, S ₂ is a select one switch, S ₃ is a minus one switch,
S ₄ is an off switch, which is located on each control panel. 1 is a remote control circuit for the tape recorder, in which the tape recorder 2 is turned on by turning on switches S ₁ to S ₃ , while the switch S ₄ is turned on.
The tape record 2 is brought to a stop state by the operation and a stop control signal, which will be described later.

Each track of the four channels of magnetic tape in the tape recorder 2 records the conversations of different people, and when the tape is played back, each track is recorded on the terminals 2 ₁ , 2 ₂ , 2 ₃ , 2 _{4 .} Conversation materials for each individual recorded in (1), (2), (3), (4)
is taken out. 3 is an encoder circuit, which outputs H as shown in _{FIG .}
The configuration is such that a level signal and an L level signal are taken out and supplied to latch circuits 4 ₁ and 4 ₂ .

Here, for example, when the conference switch _S1 is turned on, the latch circuit 42 is switched from the encoder circuit 3 to the latch circuit _42.
An L level signal is supplied to the latch circuit ₄₁ , an H level signal is supplied to the latch circuit 41, and switch switching signals are taken out from the latch circuits ₄₂ and _41, respectively, and the switch circuits _{51 to} 55
₄ and 6b are turned off, and the switch circuit 6a is turned on. This allows input terminals (teaching material terminals) 2 ₁ to 2
The teaching materials (1) to (4) of each track that have entered ₄ are mixed through input buffer circuits ₇₁ and ₇₄ and resistors _R1 to _R4 , respectively, and are mixed into a phase inversion circuit 8 having a configuration as shown in FIG.
After the phase is inverted and the teaching material {(1)+( ₂ )+( ₃ )+( _{4 )} } Terminal 10 ₁ , 10
₂ , 10 ₃ and 10 ₄ . The respective resistances of the phase inversion circuit 8 are set as follows: R ₁ =R ₂ =R ₃ =R ₄ =R ₅ .

In this way, as shown in FIG.
Teaching materials {(1)+(2)+(3)+(4)} in which signals from terminals 2 ₁ to 2 ₄ are mixed are taken out from terminals _{0 1} to 10 ₄ , respectively, and the learner reads the teaching materials {(1) ) + (2) + (3) + (4)}, the overall state of the conversation can be grasped.

In addition, output buffer circuits 9 ₁ to 9 may be added as necessary.
A phase inversion circuit may be provided after each of the outputs _{4 and 4} to invert the phase of each output to output the teaching material {(1)+(2)+(3)+(4)}.

When the output from the phase inversion circuit 8 disappears, this is detected by the no-signal detection circuit 11, and is supplied as a stop control signal by the NOR gate 12 to the remote control circuit 1, thereby stopping the tape running of the tape recorder 2. and then rewinded to the original position.

Next, when you turn on Select One Switch S ₂ ,
The encoder circuit 3 supplies an H level signal to the latch circuit ₄₂ and an L level signal to the latch circuit ₄₁ , turning on the switch circuits ₅₁ to ₅₄ and 6b and turning off the switch circuit 6a. As a result, the teaching materials (1) taken out from the input buffer circuits 7 ₁ to 7 ₄ , respectively.
- (4) are switch circuits 5 ₁ - 5 ₄ and resistors R ₁₁ -
R ₁₄ and are taken out from output terminals 10 ₁ to 10 ₄ via output buffer circuits 9 ₁ to 9 ₄ , respectively.

In this way, the teaching material (1) is taken out from the terminal 10 ₁ , the teaching material (2) is taken out from the terminal 10 ₂ , the teaching material (3) is taken out from the terminal 10 ₃ , and the teaching material (4) is taken out from the terminal 10 4 _.
By appropriately selecting and listening to programs from 0 ₁ to 10 ₄ , you can practice only a certain person's conversation.

Next, when the minus one switch S ₃ is turned on, the latch circuits 4 ₂ , 4 ₁ are connected to the encoder circuit 3.
Both are supplied with H level signals, and the switch circuit 5
₁ to 5 ₄ and 6a are turned on, and the switch circuit 6b is turned off. As a result, from terminal 10 ₁ , the teaching material {(1)
+(2)+(3)+(4)} and the teaching material (1), that is, {(2)+(3)+(4)}, is taken out and connected to the terminal 10 in the same way.
From _{terminal 2} , teaching material {(1)+(3)+(4)}, from terminal 10 _{to 3} , teaching material {(1)+(2)+(4)}, from terminal 10 _{to 4} , teaching material {(1)
+(2)+(3)} are respectively taken out. In this case as well, the phase is reversed as necessary and the teaching materials {(2+(3)+(4)}, {(1)+
(3)+(4)}, {(1)+(2)+(4)}, or {(1)+(2)+(3)}.

In this way, the terminals 10 ₁ to 10 ₄ receive teaching materials in which only the teaching materials corresponding to the terminals 2 ₁ to 2 ₄ are removed and other teaching materials are mixed, and the learner can, for example, only listen to his or her own conversation. You can practice conversation by listening to the conversations that have been removed and adding your own conversations to them.

In this case, the switch circuits 5 ₁ , 5 ₂ , 5
₃ , 5 ₄ , level and resistance of teaching material signals (1), (2), (3), (4) taken out via resistors R ₁₁ , R ₁₂ , R ₁₃ , R ₁₄
Teaching material signal extracted via R ₁ , R ₂ , R ₃ , R ₄ , phase inversion circuit 8, switch circuit 6a, resistors R ₂₁ , R ₂₂ , R ₂₃ , R ₂₄ {(1)+(2)+ (3)+(4)} signal (1),
The resistance value of each resistor and the on-resistance of the switch circuit and phase inversion circuit are respectively set so that the levels (2), (3), and (4) are equal.

If you wish to stop during the above three steps, turn on the off switch _S4 . Both latch circuits 4 ₂ and 4 ₁ are L from the encoder circuit 3.
A level signal is supplied to the switch circuits 5 ₁ to 5
₄ and 6a are turned off, and the switch circuit 6b is turned on. As a result, the teaching material is not taken out from the terminals ₁₀₁ to ₁₀₄ , and on the other hand, no signal is taken out from the phase inversion circuit 8, so the tape recorder 2 enters the stop mode.

As shown in FIG. 4, the three steps of conference, select one, and minus one are generally carried out in this order, and a teacher or the like provides guidance upon completion of each step (discussion).

In addition to the method of reproducing the teaching materials (1), (2), (3), and (4) respectively recorded on the four tracks of the tape of one tape recorder as in the above embodiment, for example, two
The teaching materials (1) and (2) recorded on two tracks may be played back, and the teaching materials (3) and (4) may be output from the microphone circuit for the teacher's conversation each time, or a separate tape may be used for each teaching material. A recorder may be provided and each teaching material may be output from the recorder.

Further, although the above embodiment relates to conversation learning, the same applies to ensemble learning, so the explanation thereof will be omitted.

As described above, the teaching material sending device according to the present invention includes a tape recorder in which a plurality of different teaching material signals are respectively recorded and which simultaneously reproduces and outputs each of the plurality of teaching material signals to a plurality of teaching material terminals by operation, and a plurality of teaching material terminals. A tape recorder is played by operating the mode selection switch, which has multiple output terminals that output teaching material signals corresponding to each of the modes, and multiple mode selection switches that select conference mode, select one mode, and minus one mode, respectively. mode, rewinds the magnetic tape at the end of playback, locates the beginning of the teaching material signal, and controls the output terminal to output the teaching material signal corresponding to each mode by operating the mode selection switch. Three steps, Conference, Select One, and Minus One, can be performed with a simple switch operation, saving teachers the trouble of editing commercially available tapes that have been recorded with each of the three step teaching materials. It can reduce the burden, and
Since a tape recorder is used, the content of the teaching materials can be changed as appropriate, and the content is richer than in the past, where teaching materials with uniform content could only be obtained by simply playing commercially available tapes. It has features such as being able to provide educational materials for students.
