  • 본 연구는 웹기반 교수 시스템을 이용하는 학습자의 지식 수준을 지능적으로 진단하기 위하여 문항 반응을 이용한 진단 모듈의 설계와 구현에 관하여 다룬다. 문항 반응 이론은 기존의 학습자 검사 방법처럼 전체 문항에서 정답 문항의 총점에 근거를 두고 학습자를 진단하는 것이 아니라 문항 하나 하나에 근거를 두고 학습자의 지식 수준을 검사하는 것이다. 기존의 웹기반 교수 시스템의 경우 학습자의 지식 수준은 고려하지 않고 검사의 총점 결과만을 가지고 진단한 뒤 그 결과를 토대로 이분법적인 학습을 진행하는 오류를 범하고 있다. 이는 학습자의 올바른 진단이 될 수 없으며 학습자 모델을 구성하기가 어려워 진보한 지능형 교수 학습 시스템에 적용하기 어렵다. 따라서 본 연구에서는 기존에 연구된 문항 반응 이론을 수학 학습에 응용하여 학습자의 지식 수준을 진단하기 위한 학습자 진단 모듈의 설계 및 구현에 대한 방향을 제시하고자 한다.

  • One of the main factors that determine the quality of instruction is the teaching ability of the instructor administering the class. To evaluate teaching ability, methods such as peer review, student feedback, and teaching portfolio can be used. Among these, because feedback from the students is directly associated with how well the students feel they have learned, it is essential to improving instruction and teaching ability. The principal aim of instruction evaluation lies in the evaluation of instructor's qualification and the improvement of instruction quality by enhancing professionalism. However, the mandatory instruction evaluations currently being carried out at the term's end in universities today have limitations in improving instruction in terms of its evaluation items and times. To improve the quality of instruction and raise teaching abilities, instruction evaluations should not stop at simply being carried out but also be utilized as useful data for students and teachers. In other words, they need to be used to develop teaching and improve instruction for teachers, and consequently, should also exert a positive influence on students' scholastic achievements and learning ability. The most important thing in evaluation is the acquisition of accurate information and how to utilize it to improve instruction. The online instruction diagnosis item pool is a more realistic feedback device developed to improve instruction quality. The instruction diagnosis item pool is a cafeteria-like collection of hundreds of feedback questions provided to enable instructors to diagnose their instruction through self-diagnosis or students' feedback, and the instructors can directly select the questions that are appropriate to the special characteristics of their instruction voluntarily make use of them whenever they are needed. The current study, in order to find out if the online instruction diagnosis item pool is truly useful in reforming and improving instruction, conducted pre and post tests using 256 undergraduate students from Y university as subjects, and studied the effects of student feedback on instructions. Results showed that the implementation of instruction diagnosis improved students' responsibility regarding their classes, and students had positive opinions regarding the usefulness of online instruction diagnosis item pool in instruction evaluation. Also, after instruction diagnosis, analyzing the results through consultations with education development specialists, and then establishing and carrying out instruction reforms were shown to be more effective. In order to utilize the instruction diagnostic system more effectively, from planning the execution of instruction diagnosis to analyzing the results, consulting, and deciding how those results could be utilized to instruction, a systematic strategy is needed. In addition, professors and students need to develop a more active sense of ownership in order to elevate the level of their instruction.

  • The purpose that the curriculum appropriate for the student's level pursues is to offer to a student the curriculum that can satisfy the student's interest, aptitude, and requirements. This curriculum has recently enforced all over the country, but the careful research and the plan for verification on its effect are required so that it may accomplish its purpose. This study, centered on the reading comprehension ability of Freshman English of the High School, aims to suggest a more desirable procedure for organizing and enforcing the curriculum appropriate for the students' level. In order to provide the best curriculum appropriate for the student's level. (1) the diagnosis of the individual student's level should be made first ; (2) the syllabus focused both on the grammar and on the communicative functions should be prepared ; (3) the teaching material on the basis of the syllabus should be selected considering the student's interest. and requirements. The new method of teaching-learning English should also be developed with the enforcement of the new curriculum discussed here. The curriculum appropriate for the student's level has many kinds of problems but these disadvantages should be overcome for providing the better educational system for the individual student.

  • Coronary artery disease (CAD) is a major cause of death in the world. As a non-invasive imaging modality, computed tomography angiography (CTA) is now usually used in clinical practice for CAD diagnosis. Precise quantification of coronary stenosis is of great interest for diagnosis and treatment planning. In this paper, a novel cluster method based on a Modified Student's t-Mixture Model is applied to separate the region of vessel lumen from other tissues. Then, the area of the vessel lumen in each slice is computed and the estimated value of it is fitted with a curve. Finally, the location and the level of the most stenoses are captured by comparing the calculated and fitted areas of the vessel. The proposed method has been applied to 17 clinical CTA datasets and the results have been compared with reference standard degrees of stenosis defined by an expert. The results of the experiment indicate that the proposed method can accurately quantify the stenosis of the coronary artery in CTA.

  • Ability diagnosis is similar to medical diagnosis from a number of perspectives. However, a medical diagnosis is carried out by a direct observation through medical apparatuses, while an ability diagnosis is made by an indirect observation in the from of testing. In this respect, ability diagnosis is more difficult than medical diagnosis. Confined to middle school 1st year Mathematics, we collected survey data in 1996 from monthly tests. The data consist of student responses to diagnosis results on their abilities and of the effects of catch-up guidances for individual students which are provided based on their ability diagnosis outcomes. We analyzed the data and summarized the result in the paper. One of the main results is that the ability diagnosis as used in the paper has a very positive effect on catch-up study. But it is important to note that the effects vary across the ability groups, the effect appearing weaker in the lower ability group than in the higher ability group. This calls our attention to the need that the ability diagnosis and guidance for the catch-up study be differentiated among ability groups.

  • With the popularity of online learning, intelligent tutoring systems are starting to become mainstream for assisting online question practice. Surrounded by abundant learning resources, some students struggle to select the proper questions. Personalized question recommendation is crucial for supporting students in choosing the proper questions to improve their learning performance. However, traditional question recommendation methods (i.e., collaborative filtering (CF) and cognitive diagnosis model (CDM)) cannot meet students' needs well. The CDM-based question recommendation ignores students' requirements and similarities, resulting in inaccuracies in the recommendation. Even CF examines student similarities, it disregards their knowledge proficiency and struggles when generating questions of appropriate difficulty. To solve these issues, we first design an enhanced cognitive diagnosis process that integrates students' affection into traditional CDM by employing the non-compensatory bidimensional item response model (NCB-IRM) to enhance the representation of individual personality. Subsequently, we propose an affection-enhanced personalized question recommendation (AE-PQR) method for online learning. It introduces NCB-IRM to CF, considering both individual and common characteristics of students' responses to maintain rationality and accuracy for personalized question recommendation. Experimental results show that our proposed method improves the accuracy of diagnosed student cognition and the appropriateness of recommended questions.
