SERVER AND METHOD FOR MANAGING LEARNING

RELATED APPLICATIONS

This application claims the priority of Korean Patent Application No. 10-2013-0132541, filed on Nov. 1, 2013, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.

BACKGROUND

1. Field

One or more embodiments of the present invention relate to a server and method for managing learning, and more particularly, to a server and method for managing learning, by which a correct answer ratio is checked based on a real-time solving process and solving time of a question set to a learner by using a terminal such as a computer or a portable terminal such as a smartphone in order to induce the learner to sincerely learn.

2. Description of the Related Art

As the Internet and personal communication technologies have recently developed, learning methods using electronic tools, such as remote learning, video learning, or the like, have been widely used in the learning field. According to these learning methods, lectures are given and test papers are solved on-line, and learning is performed only in a fixed position by using an individual personal computer (PC). However, as use of apparatuses using wireless Internet has recently rapidly increased, online learning is possible by using a smartphone, a tablet PC, or the like while walking or moving.

This form of online learning enables a learner to access a server through the internet to access learning materials stored in the server in order to learn. Therefore, like an existing learning video tape, a student may unilaterally receive an audio-visual education. However, it is difficult to manage insincere attitudes of students that frequently occur in on-line learning.

Also, online learning is performed only by one-way audiovisual education, and thus it is impossible to check a solving process of a question that is directly solved by a student like a mathematical question or the like. Therefore, many learners mistakenly recognize wrong solving processes as correct processes if answers to questions are correct. Also, when the learners recognize that if convincing solving processes are wrong, the learners are not convinced of solving processes of all questions with which the learners are well-acquainted. In serious cases, the learners lose self-confidence and thus lose their desire to learn.

FIG. 1 is a view illustrating a learning management system according to an embodiment of the present invention.

Referring to FIG. 1, the learning management system includes a learner terminal 100, a manager terminal 200, and a learning management server 300. The learning management system may further include other elements besides the above-mentioned elements.

The learner terminal 100 and the manager terminal 200 are apparatuses that may access the learner management server 300 through a communication network such as the Internet. The learner terminal 100 and the manager terminal 200 may be mobile terminals such as notebook computers, hand-held devices, smartphones, taps, tablet personal computers (PCs), or the like, desktop computers, or arbitrary apparatuses that use these devices or are directly or indirectly connected to these devices.

The learner terminal 100 accesses the learning management server 300 to download and install a learning management application for solving a set question and checking a solving result in real time.

The learner terminal 100 executes the learning management application to access the learning management server 300, receives a pre-registered question from the learning management server 300, and displays the pre-registered question. Here, the question may include various types of questions. For example, if a learner is a high school student, the question may be questions of curriculum subjects such as Korean, English, mathematics, etc. Alternatively, the question may be a question that is used by designated education institutes to evaluate learners according to class units, school units, city units, province units, and nation units. The question may also be a subjective question, an objective question, a question requiring a solving process, or an essay question requiring opinions of an examinee. When the learner terminal 100 receives a question from the learning management server 300, the learner terminal 100 may receive and display a time limit taken for solving each question together.

The learner terminal 100 may record a solving process in an area based on the question received from the learning management server 300. Here, the solving process may indicate a series of mathematical equations for obtaining a correct answer if the question is a mathematical question. If the question is an essay question, the solving process may be a sentence or a paragraph including a series of words for obtaining a correct answer. Although the question is an objective question, the learner terminal 100 may record a selected correct answer along with the solving process.

The learner terminal 100 may completely write the solving process of the question and transmit an answer to the question and/or the solving process of the question to the learning management server 300. Here, the learner terminal 100 may also transmit a solving time of the question. Alternatively, the learner terminal 100 may transmit a result value indicating whether the question is solved within the time limit, to the learning management server 300.

The learning management server 300 may provide the learner terminal 100 with a result of whether a question solving time, a correct answer ratio, solving process accuracy and/or a time limit have been kept, according to a request of the learner terminal 100.

The question solving process accuracy may be automatically calculated by a program stored in the learning management server 300 but is not limited thereto. Alternatively, the manager may check a question solving process of a learner and then input an evaluation result of accuracy of the question solving process.

FIG. 9 is a schematic block diagram illustrating a structure of the learning management server 300, according to an embodiment of the present invention.

Referring to FIG. 9, the learning management server 300 includes a certifying module 301, a question providing module 302, a time checking module 303, a solving process checking module 304, a correct answer ratio calculating module 305, a learning evaluating module 306, and a database (DB) 350 including a question DB 310, a learner information DB 320, and a manager information DB 330.

The certifying module 301 performs certifications of a learner and a manager in real time based on information stored in the learner information DB 320 and the manager information DB 330.

The question providing module 302 provides the learner terminal 100 with a question stored in the question DB 310 and a solving time limit of the question in real time. Here, although not shown in the question DB 310, the question DB 310 may periodically receive and store a question and a solving time limit of the question from a question setting terminal (not shown). The question DB 310 stores information related to an answer to the question. The question providing module 302 may provide the manager terminal 200 with the question stored in the question DB 310 and the solving time limit of the question.

The time checking module 303 checks a question solving time transmitted from the learner terminal 100 in real time. Since the time checking module 303 is connected to the correct answer ratio calculating module 305, the correct answer ratio calculating module 305 processes an answer of a learner who exceeds a time limit, as a wrong answer according to a check result of the time checking module 303.

Alternatively, the correct answer ratio calculating module 305 may calculate a correct answer ratio based on a time limit exceeding rate checked by the time checking module 303. For example, if the learner exceeds a first time limit (for example, 10 seconds) according to a time check result of the time checking module 303, the correct answer ratio calculating module 305 may lower the correct answer ratio by 5%. If the learner exceeds a second time limit (for example, 30 seconds) according to the time check result of the time checking module 303, the correct answer ratio calculating module 305 may lower the correct answer ratio by 10%. In order to provide a time-based correct answer ratio according to a rate of exceeding a time limit as described above, a correct answer ratio may be lowered rather than processing an answer of a learner who solves a question in excess of a time limit as a wrong answer to induce a learning performance. Here, a time limit exceeding rate and a lowering range of a correct answer ratio may be flexibly adjusted, for example, may be adjusted by a manager.

The solving process checking module 304 checks the question solving process transmitted from the learner terminal 100 in real time. The solving process checking module 304 may compare the question solving process transmitted from the learner terminal 100 with an answer keyword stored in the question DB 310 and calculate solving process accuracy according to the number of question solving processes and answer keywords that match each other. For example, if there are 10 answer keywords of a question, and a solving process includes 10 answer keywords, solving process accuracy is 100%. The solving process accuracy is not acquired only by the solving process checking module 304 and may be calculated by an input of a manager as described above. Alternatively, a part of the solving process accuracy may be performed by the solving process checking module 304, and the other part of the solving process accuracy may be performed by an input of the manager.

Since the solving process checking module 304 is connected to the correct answer ratio calculating module 305, the correct answer ratio calculating module 305 may perform correct answer processing if the solving process accuracy checked by the solving process checking module 304 is higher than or equal to a reference rate, for example, is higher than or equal to 90%.

Alternatively, the correct answer ratio calculating module 305 may calculate a solving process accuracy-based correct answer ratio based on a solving process accuracy rate checked by the solving process checking module 304. For example, if the solving process accuracy rate is in a first range (for example, between 80% and 89%) according to a solving process accuracy check result of the solving process checking module 304, the correct answer ratio calculating module 305 may lower a correct answer by 5%. If the solving process accuracy rate is in a second range (for example, between 70% and 79%) according to the solving process accuracy check result of the solving process checking module 304, the correct answer ratio calculating module 305 may lower the correct answer ratio by 10%. In order to provide a time-based correct answer ratio based on a solving process accuracy rate, a correct answer ratio may be lowered rather than processing an answer of a learner who writes a less accurate solving process as a wrong answer to induce a learning performance. Here, a solving process accuracy rate and a lowering range of a correct answer ratio may be flexibly adjusted, for example, may be adjusted by the manager.

The correct answer ratio calculating module 305 calculates the correct answer ratio in real time by using various methods. For example, although solving process accuracy of a question of a learner who exceeds a time limit is higher than or equal to a reference rate, an answer of the learner may be processed as a wrong answer. Alternatively, although the learner writes a solving process within the time limit, and the solving process accuracy is lower than or equal to the reference rate, the answer of the learner may be processed as the wrong answer. Also, if the solving process accuracy is higher than or equal to the reference rate in the time limit, the answer of the learner may be processed as a correct answer. As described, a time-based correct answer ratio and a solving process accuracy-based correct answer ratio may be summed to calculate a correct answer ratio. Here, the correct answer ratio may be expressed as “correct and/or wrong” or as a percentage. However, the present invention is not limited thereto, and the correct answer ratio may be expressed by using various methods.

The learning evaluating module 306 analyzes the question solving time, the question solving process accuracy, and the correct answer ratio and generates learning evaluation contents including accuracy of the learner according to the analysis result. A process of calculating accuracy will now be described. A first weight may be applied to the question solving time, and a second weight may be applied to the question solving process accuracy to sum the question solving time and the question solving process accuracy in order to calculate accuracy. Here, the first and second weights may be flexibly adjusted, for example, may be adjusted by the manager. A manager who gives considerable thought to the question solving time may set the first weight to be higher than the second weight. A manager who gives considerable thought to the question solving process may set the second weight to be higher than the first weight.

The learning evaluating module 306 may provide the manager terminal 200 with the generated learning evaluation contents in text form and/or graphical form according to a request of the manager terminal 200. The learning evaluating module 306 may provide the learner terminal 100 with the learning evaluation contents, except for the accuracy, according to a request of the learner terminal 100.

FIG. 10 is a flowchart illustrating a process of generating learning evaluation contents through a learning management server and providing the learning evaluation contents from the learning management server to a manager terminal and a learner terminal, according to an embodiment of the present invention.

Referring to FIG. 10, in operation S100, the learning management server 300 provides a question and a question solving time limit in real time to the learner terminal 100 that succeeds in being certified.

In operation S110, the learning management server 300 receives a question solving process and a question solving time from the learner terminal 100 in real time.

In operation S120, the learning management server 300 compares the question solving time of a learner received in real time with a time limit and, if the question solving time of the learner exceeds the time limit, processes an answer of the learner as a wrong answer. Here, according to another method, the learning management server 300 may calculate a time-based correct answer ratio based on a time limit exceeding rate. For example, if the question solving time of the learner exceeds a first time range (for example, 10 seconds) according to a time check result of the time checking module 305, the correct answer ratio calculating module 305 may lower a correct answer ratio by 5%. Here, a time limit exceeding rate and a lowering range of a correct answer ratio may be flexibly adjusted, for example, may be adjusted by a manager. The learning management server 300 may not provide a question solving time limit to the learner terminal 100. In this case, the learning management server 300 may have a preset reference time of question solving and process an answer of a learner who receives a question in real time as a wrong answer or calculate a time-based correct answer ratio according to whether a question solving time of the learner exceeds the preset reference time.

In operation S130, the learning management server 300 compares the question solving process received in real time with an answer keyword stored in a question DB and calculate solving process accuracy according to the number of question solving processes and answer keywords that match each other. For example, if there are 10 answer keywords of a question, and a solving process includes 10 answer keywords, solving process accuracy is 100%. Here, the learning management server 300 may calculate a solving process accuracy-based correct answer ratio based on a solving process accuracy rate. For example, if the solving process accuracy is in a first range (for example, between 80% and 89%) according to a solving process accuracy check result, the correct answer ratio calculating module 305 may lower the correct answer by 5%.

In operation S140, the learning management server 300 calculates a correct answer ratio in real time based on the question solving time and the question solving process. Here, the correct answer ratio may be calculated by using several methods. Therefore, although solving process accuracy of a question of a learner who exceeds a time limit is higher than or equal to a reference rate, an answer of the learner may be processed as a wrong answer. Alternatively, although a solving process is written within the time limit, and the solving process accuracy is lower than or equal to the reference rate, the answer of the learner may be processed as a wrong answer. Also, if the solving process accuracy is higher than or equal to the reference rate in the time limit, the answer of the learner may be processed as a correct answer. In addition, a time-based correct answer ratio and a solving process accuracy-based correct answer ratio may be summed to calculate a correct answer ratio as described above. Here, the correct answer ratio may be expressed as “correct and/or wrong” or as a percentage. However, the present invention is not limited thereto, and the correct answer ratio may be expressed by using various methods.

In operation S150, the learning management server 300 analyzes the question solving time, the question solving process accuracy, and the correct answer ratio and generates learning evaluation contents including accuracy according to the analysis result. A process of calculating the accuracy will now be described. A first weight may be applied to the question solving time, and a second weight may be applied to the question solving process accuracy to sum the question solving time and the question solving process accuracy in order to calculate the accuracy. Here, the first and second weights may be flexibly adjusted.

In operation S160, the learning management server 300 transmits the learning evaluation contents in text form and/or graphical form to the manager terminal 200 in real time according to a request of the manager terminal 200 that succeeds in being certified.

In operation S170, the learning management server 300 transmits the learning evaluation contents that are in text form and/or graphical form, except for the accuracy, to the learner terminal 100 in real time according to a request of the learner terminal 100.

As described above, according to the one or more of the above embodiments of the present invention, a correct answer ratio may be checked based on a real-time solving process and a solving time of a question set to a learner by using a terminal such as a computer or a portable terminal such as a smartphone to induce sincere learning of the learner. Also, real-time solving process and solving time of a question set to a learner by using a terminal such as a computer or a portable terminal such as a smartphone may be checked regardless of a time or place to improve an interest in learning of the learner.

The learner may check a correct answer ratio of the question solved by the learner in real time to improve a learning performance.

The present invention may also be embodied as computer readable code on a computer readable recording medium. The computer readable recording medium is any data storage device that can store data which can be thereafter read by a computer system. Examples of the computer readable recording medium include read-only memory (ROM), random-access memory (RAM), CD-ROMs, magnetic tapes, floppy disks, optical data storage devices. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. Also, functional programs, codes, and code segments for accomplishing the present invention can be easily construed by programmers of ordinary skill in the art to which the present invention pertains.
