Abstract

PURPOSE: A system and a method for a computer based certification examination by adjusting the difficulty of a problem are provided to extract/evaluate the problems fit to a capability of each examinee by differently drawing out the next problem from a database of server whether the examinee presents a wrong or a right answer. CONSTITUTION: The system collects the examinee as a member. An examination authority installing a local server constructs the information related to a customer. Online test applicants solve the problem without a download delay by receiving the next problem while the online test applicants solve the problem. The more efficient and accurate evaluation is enabled by solving only the problems adjusting the difficulty depending on the capability of the applicant.

Description

문제의 난이도 조절에 의한 컴퓨터 기반의 인증 시험 시스템 및 방법 {The system and method under the computer based examination which is the adaptive system}The system and method under the computer based examination which is the adaptive system

본 발명은 컴퓨터와 온라인망을 기반으로 하여 인증 시험 및 각종 모의 시험 서비스에 관한 것으로, 문제의 난이도가 조절이 되고 각 문제당 배점에 차등을 두는 각종 시험 서비스 시스템 및 방법에 관한 것이다.The present invention relates to a certification test and various simulated test services based on a computer and an online network. The present invention relates to various test service systems and methods in which a difficulty level of a problem is controlled and a grade is assigned to each problem.

현재 시행되어지고 있는 각종 시험의 형태는 획일적인 지필 기반의 시험 형태이다. 시험을 시행할 경우 수험생들은 정해진 시험 장소로 이동해야 하며, 그에 따른 재정적, 시간적인 낭비를 경험하고 있다. 또한 시험 문제의 유출이라는 결정적인 문제점을 해결하지 못하고 있으며, 해결책도 마련되지 못하고 있다.The various types of tests currently being conducted are uniform paper-based tests. In the case of testing, candidates are required to move to a designated test site and experience financial and time wastage. In addition, it does not solve the critical problem of leakage of test questions, and no solution is provided.

본 발명은 문제은행을 기반으로 하여 이루어진다. 문제은행이란 현재까지 출제된 문제와 지속적으로 개발되어지는 문제를 데이타베이스에 보관하는 시스템이다. 데이타베이스에 보관된 각 문제들은 각각의 난이도를 가지게 되며, 난이도는 수험생들의 정답률에 비례하여 배점이 정하여 진다. 문제를 푸는 수험생들은 각자의 실력에 의해 다음 문제가 결정이 되며, 문제는 데이타베이스에서 실시간추출되어 전송된다. 이런한 점들이 문제 유출에 대한 충분한 해결책이 된다.The present invention is based on the question bank. The problem bank is a system that keeps the questions that have been raised to date and the ones that are being developed continuously in the database. Each question stored in the database has a different difficulty level, and the difficulty level is assigned to the examinee's percentage of correct answers. The candidates who solve the problem are determined by their skills and the problem is extracted from the database in real time. These points are a sufficient solution to the problem leak.

본 발명은 종래의 지필식 방식의 문제점을 해소하기 위하여 고안된 것으로서, 난이도 조절에 의한 시험 방식을 채택하였고 온라인망을 통하여 문제를 송출하며 각 문제들은 암호화되어 서버 분산 방식을 통하여 전송되어진다. 각 문제는 단어별로 암호화되며 여러 서버에 분산되어진 암호들이 모여 한개의 문제를 완성한다. 이러한 시스템을 이용하여 시험의 평가상의 신뢰도를 높인다.The present invention is designed to solve the problems of the conventional paper-based method, adopting the test method by the difficulty control and sending out problems through the online network, each problem is encrypted and transmitted through the server distribution method. Each problem is encrypted word-by-word, with passwords distributed across multiple servers to complete one problem. This system is used to increase the evaluation reliability of the test.

본 발명은 비지니스 모델에 관한 발명으로 전체적인 구성은 도 1과 같으며 관리서버가 온라인망에 접속되어 있으며 로컬서버와 수험생의 컴퓨터도 온라인망에 접속되어 있어 각 서버와 수험생 컴퓨터들 사이에서 데이터를 서로 유기적으로 주고 받을 수 있다.The present invention relates to a business model, the overall configuration of which is shown in Figure 1, the management server is connected to the online network, and the local server and the examinee's computer is also connected to the online network, so that the data between each server and the examinee computers You can give and receive organically.

이하, 본 발명의 바람직한 실시 예를 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명에 따른 컴퓨터를 이용한 시험 시스템의 전체적인 구성도를 도시한 것으로 이 컴퓨터를 이용한 시험 시스템은 먼저 수험생을 회원으로 모집하고 로컬서버가 설치된 시험기관에 고객의 관련 정보 데이타베이스를 구축한다.1 is a diagram showing the overall configuration of a computer-based test system according to the present invention. The computer-based test system first recruits examinees as members and constructs a database of relevant information of customers in a test institute where a local server is installed. .

본 발명을 통해서 온라인 테스트 응시자들은 자신이 문제를 푸는 동안에 다음 문제를 전송 받음으로써 다운로드 지연없이 문제를 푸는 것이 가능하게 되며, 응시자의 실력에 크게 벗어나는 문제들이 아닌 응시자의 실력에 따라 난이도가 조절된 문제들만을 풀게 됨으로써 보다 효율적이고 정확한 평가가 가능하여 교육적 효과가 배가된다. 또한 문제 콘텐츠 공급자 측면에서는 각 문제별로 시간이 지나게 됨에 따라서 응시자들의 정답 및 오답의 분포 데이터가 축적됨으로써 문제의 난이도가 자동적으로 결정되므로 문제의 질을 최선으로 유지할 수 있는 장점이 있다.Through the present invention, the online test candidates can solve the problem without a download delay by receiving the next problem while solving the problem, and the difficulty is adjusted according to the testee's ability rather than a problem that greatly deviates from the candidate's ability. Only by solving the problem, more efficient and accurate evaluation is possible, which doubles the educational effect. In addition, the problem content provider has the advantage of maintaining the best quality of the problem because the difficulty of the problem is automatically determined by accumulating the distribution of correct and incorrect answers of candidates as time passes for each problem.

또한 컴퓨터를 이용한 시험 개발및 컨텐츠 개발뿐만 아니라 기존의 서비스 업체를 업무 협력관계를 체결하고 그 협력업체에서 서비스하는 모의 시험 결과에 대해서도 관리서버로 자동으로 통합관리를 해 줌으로서 사용자에게는 시험 처리 결과를 보다 신속하게 확인할 수 있는 기능을 제공한다.In addition, test management and content development using computers, as well as the conclusion of a business cooperation relationship with the existing service provider, and automatically manages the integrated test results to the management server for the simulation test results serviced by the supplier to the user to receive the test processing results It provides the ability to check more quickly.

본 발명에 의한 자격 및 인증시험 서비스 시스템 및 방법은 대부분의 대단위 자격시험을 그 대상으로 한다. 예컨데, 자동차 운전면허 시험, 대입 수학능력 시험, 영어평가 시험 등 각종 국가에서 시행하는 자격 및 선발 시험이 모두 대상이 된다고 볼 수 있다.Qualification and certification test service system and method according to the present invention is intended for most large-scale qualification examinations. For example, qualifications and selection tests conducted in various countries, such as the driver's license test, the college entrance exam, and the English test, are all eligible.

전국적으로 자격시험센터를 설립하는 문제도 국가 예산으로 역시 쉽지 않은 문제이며, 이를 설립한다 하더라도 관리상의 문제 또한 어려운 점이 많다. 따라서, 시스템상의 관리는 민간업체에게 이양하고, 정보의 관리당국은 그 업체를 관리하는데 필요한 최소한의 비용을 지불하는 방향으로 나아가야 한다. 이에 대해 본 발명은 민간업체에서 관리하는데 있어 최적의 시스템을 제공한다.Establishing a national testing center is also a difficult problem for the national budget, and even if it is established, management problems are also difficult. Therefore, the management of the system should be handed over to the private sector, and the authorities of the information should move towards paying the minimum costs necessary to manage the company. In contrast, the present invention provides an optimal system for managing in a private company.

본 발명에 의한 온라인 테스트 서비스가 전국적으로 확대되어 설치된다면, 수험자들은 가깝고 편리한 장소에서 각종 시험을 이용할 수 있으며, 범국민적인 컴퓨터 교육에도 큰 도움을 줄 수 있다. 또한 수험생들의 이동에 따른 비용 및 시험 시간도 획기적으로 줄일 수 있으며, 시험 문제의 유출을 원천적으로 방지할 수 있다.If the online test service according to the present invention is expanded and installed nationwide, examinees can use a variety of tests in a near and convenient place, it can be a great help to the national computer education. In addition, the cost and test time of the examinee's movement can be greatly reduced, and the leakage of test questions can be prevented at the source.

본 발명은 시스템에 의해 시험장의 기본적인 보안 문제를 해결하고, 보안을 위한 별도의 관리를 불필요하게 한다. 또한 축적된 자료에 의해 난이도가 결정되므로 시험 문항의 자체 적정성 여부에 대한 검증도 수반되어지는 장점이 있다.The present invention solves the basic security problem of the test site by the system, and makes separate management for security unnecessary. In addition, since the difficulty is determined by the accumulated data, there is an advantage in that verification of the test item's own adequacy is also accompanied.
