Description

Big data-based learner-customized foreign language level measurement system

The present invention relates to a system for measuring a learner's foreign language level based on big data, and to a system for measuring a learner's foreign language level by providing items suitable for the learner's foreign language level and storing and analyzing response information.

In general, as foreign language ability is regarded as important in modern society, various language institutes and textbooks are increasing. The number of people receiving education is increasing.

Therefore, language institutes and foreign language education sites are used to measure learners' abilities through foreign language level tests and to recommend appropriate educational programs. The normal foreign language level test is a one-time use only for the first time, and the questions asked do not consider the learner's ability, but only the preset questions, so the reliability of the learner's ability measurement is low.

In addition, each foreign language learning site develops its own foreign language level test method, which incurs a lot of development cost, has a different difficulty level for each foreign language level test, and has a small amount of stored learner information, so that the reliability of comparative analysis results on learner skills is low.

Accordingly, Korean Patent Laid-Open Patent Publication No. 10-2012-0007404 configures a learning algorithm that sets the learner level according to the learner's successive correct/incorrect answers and asks questions according to the set level. It is different from the present invention in that the foreign language level of the learner is not set by storing and analyzing .

The present invention is different from the present invention in that the foreign language level of the learner is not set by storing and analyzing the correct answer rate and learner response information for the following problems.

Therefore, when measuring a learner's foreign language level simply using the correct answer rate or correct answer information, it is impossible to accurately measure the learner's foreign language level, so there is a problem in that the learner's learning efficiency is reduced.

An object of the present invention is to increase the learning efficiency of the learner by accurately and quickly predicting the learner's foreign language level using the learner's level, response information, and continuity information.

The big data-based learner-customized foreign language level measurement system according to the present invention is problem information including item information including a fingerprint and correct answer information for a problem, and correct answer rate information, which is information about the percentage of correct answers that are correct for each learner's level with respect to the problem DB, a question selection unit for selecting a problem using the learner's temporary level and the correct answer rate information corresponding to the temporary level, a correct answer determination unit for determining whether the correct answer is given by using the learner's response information to the problem, the above A continuity determination unit that generates continuity information that is the number of times that the learner consecutively inputs correct or incorrect answers with the correct answer determination unit, and a temporary level setting unit that resets the learner's temporary level with the continuity information and the correct answer rate information may include

The question selection unit may select a question having a correct rate of 40 to 60% at the learner's temporary level.

The temporary level setting unit sets a level corresponding to the range of 60 to 80% of the correct answer rate information for the question as the temporary level when the correct answer to the selected question is the correct answer, and the correct answer to the selected question If the answer is incorrect, a level corresponding to a range of 20 to 40% of the correct rate information for the question may be set as the temporary level.

The continuity determination unit may calculate the continuity information by adding a continuous number of times when the correct answer or incorrect answer is continuous, and set the continuity information to 1 when the correct answer is not continuous.

The temporary level setting unit resets the level furthest from the temporary level to a new temporary level when there are a plurality of levels corresponding to the correct answer rate information and the continuity information is 2 or more, and when the continuity information is 1, the level closest to the temporary level can be reset to a new temporary level.

When there is no level corresponding to the range of the correct rate information, a set temporary level may be equally applied.

It may further include a final level setting unit for assigning a score for each level using Equation 1, the continuity information and the correct answer rate information, and setting a level having the highest sum of scores for each level as the final level.

[Equation 1]

Score = (number of foreign language questions provided - continuity x correction) ÷ total number of questions in the test.

When the correct answer to the selected question is the correct answer, the final level setting unit gives a score to a level corresponding to the range of 40-80% of the correct answer rate information for the question, and determines whether the correct answer to the selected question is In the case of an incorrect answer, a score may be given to a level corresponding to the range of 20 to 60% of the correct rate information for the question.

When the continuity information is 2 or more, the final level setting unit may give a score except for a level in which the correct rate information for the question is in the range of 40 to 60%.

When there is no level corresponding to the range of the correct rate information, a score may be given to the temporary level set by the temporary level setting unit.

The problem selection unit sets one of the previously set level of the learner or the level set based on the learner's age and the level set based on the learner's academic background as the learner's temporary level, .

The present invention relates to a system for measuring a foreign language level customized for a learner based on big data, and it is possible to more accurately measure a foreign language level with a smaller number of questions by analyzing the percentage of correct answers for each foreign language level and the continuity of learner response information.

In addition, there is an effect that learners' learning efficiency can be improved by providing a problem suitable for the foreign language level of the learner through accurate foreign language level measurement.
