The purpose of this study is to analyze the teachers' perceptions about the various evaluation methods used in SW education and to find ways to improve the usefulness of the field. To do this, we surveyed the teachers who were educated about SW education evaluation. As a result of the study, it was recognized that the use of output, portfolio, and observation evaluation in SW education class is suitable for evaluating Computational Thinking(CT) and useful for field application. On the other hand, paper and self-evaluation are useful for field application, but they are relatively inadequate to evaluate CT. Portfolio, design, and interview evaluations are good for measuring CT, but they are difficult to apply to the field. Also, evaluation criteria, evaluation factors, and strategies were found to be difficult to apply. Therefore, we suggest the necessary measures to apply SW education evaluation method more effectively.

Paper & pencil test provides limited informations about student. So many web-based computerized test systems are developed and tried. But These systems have drawbacks that cannot visit previous or next problems freely. So These systems cannot get deep informations such as elapsed time of each problem, history of answer modification, the number of visit time of each problem. These deep informations are very important in educational evaluation area. Therefore we develop educational evaluation system can get these deep informations including basic informations. And then we apply paper & pencil test and our system to 67 students, and execute survey. The reason of survey is to ascertain availabilty of our system.

This study was conducted to provide practical ways to apply observation assessments in classrooms. Observation assessments have been asserted to assess elements of mathematical processes which cannot be effectively assessed in traditional paper-and-pencil tests. In order to propose the ways for teachers to actively use observation assessment of mathematics assessments, relevant instruments were developed by analyzing a number of related theories. The observation assessments were applied in classroom settings and the results of this application were analyzed. The findings from this study are expected to suggest beneficial implications for teachers who are interested in practicing observation assessments in classrooms.

This study aims to examine how secondary mathematics teachers perceive and how they use constructed-response assessment in their mathematics classrooms. For this purpose, we conducted a survey in Seoul, Inchun, and Gyeonggi-do; 189 teachers participated in the survey. Results from the data analysis suggest as follows: a) the secondary mathematics teachers participated in the survey seem to consider the primary goals of assessment through constructed-response items as evaluating student achievement and the development of students' thinking and creativity; b) the teachers perceive that constructed-response assessment would promote students' mathematical thinking and problem solving skills; c) in general, constructed-response items were included in both performance assessment(less than 20 percent) and paper-and-pencil test(20 to 40 percent); and d) constructed-response items were primarily used as a part of regular examination, rather than as an independent assessment.

The aim of the study is to explore some problems that we have to solve to execute assessments effectively and in agreement with the objectives of them. We analysed the practices of some assessments Including our national assessment of educational achievement and the third international mathematics and science study with focussing on the frames of assessments, the analyses of results, and the items presented in the assessments. The results of the study are the following. Firstly, we need to make the frame of assessment to agree with the objectives of assessment and to reflect the characteristics of the item related to a few areas. Secondly, we need to analyse the results of assessment with reflecting the frames of assessment. Thirdly, we need to discuss more concretely on the level and presentation of items including the order of conditions to need to solve the items. And lastly, we need to minimize the difference caused by the variations of translation in the international assessments.

This study was to propose new formats for the records of achievement and the student's school life. For the college entrance examination to select excellent students with great potential and for the public education to be normalized through performance assessment, the implications of the reformats of the student achievement are significant. To carry out the study, 658 of students, 230 of teachers from 4 middle schools and 10 high schools, and 24 of college admission officers from 8 universities participated in the questionaries that asked the problems of the current assessment system and the future directions based on the desirable reformats of the school records. The collected opinions and advices from the participants were considered to understand the current status, possible directions, and ways to apply the performance assessment to the college entrance examination.

지필검사는 매우 제한적인 학생정보만 제공한다. 그래서 온라인상에서 웹기반으로 실시하는 컴퓨터이용검사가 개발되고 시도되어지고 있다. 그러나 이러한 기존의 시스템은 문항을 자유롭게 이동하며 시험을 치를 수 없다는 단점을 가지고 있다. 이러한 단점으로 인하여 각 문항에 소요된 시간, 답안 변경 내역, 각 문항의 방문 횟수등과 같은 심화된 정보를 얻어낼 수 없다. 이러한 심화된 정보는 교육평가 영역에서 매우 중요시되는 정보이다. 심화된 정보를 알기 위해서는 응시자가 문항을 자유롭게 이동하면서 시험을 치를 수 있어야 한다. 그래서 본 논문에서는 기존의 시스템이 제공하는 기본 정보 이외에 심화된 정보를 얻을 수 있는 시스템을 개발하였다. 개발된 시스템을 67명의 학생들에게 지필검사와 함께 각각 적용하고 설문 조사를 실시하였다.

The purpose of this study is to use as a basic data of establishing operating Course-based National Technical Qualification(CNTQ) support program by examining the educational needs for operating CNTQ of vocational school teachers, and to contribute to the vocational school settlement of CNTQ course. To achieve those purposes, this study drew 27 tasks performed by teachers operating CNTQ. Also, it surveyed the perceived importance and the performance. The findings of this study are as follows. First, it is showed that 'selection of qualification fields and confirmation of organization criteria, organization of educational training time by competency unit, organization of subjects and establishment of competency unit operating plan by grade and semester, selection of teaching materials, implementation of education and training, establishment of evaluation plan, implementation of evaluation, re-education and re-evaluation students with grades under 40%, guidance of paper evaluation, guidance of practical evaluation, guidance of interview evaluation' are the first priority tasks in the result of the need analysis. Second, it is indicated that 'application of external evaluation, guidance to retake an exam for failure' are the secondary priority tasks. According to these results, the following conclusions were made. First, it will be more positive effects if the educational needs in the next CNTQ support program include contents of the first priority tasks. Second, it is indicated that the priority of the educational needs for tasks of operating plan stages is commonly high. In particular, the highest ranking in the result means that it is completely supported from the first step on operating course. It is expected that the program which teachers on operating the course of similar qualification fields share each operating experience is effective. Third, the priority of the educational needs for external evaluation step ranked high. External evaluation has a different level of difficulty and a form of practical evaluation output according to qualification fields, so the method of guidance has to be different. It needs the program constructed by similar fields.

ICT technology has been applied to various educational fields, but applying to educational test field is limited. Computer-based test (CBT) can overcome temporal and spatial constraints of conventional paper-based test, but is vulnerable to fraud by test parties. In this paper, we propose real-time monitoring and process management methods to enhance the security of CBT. In the proposed methods, the test screens of students are periodically captured and transferred to the professor screen to enable real-time monitoring, and the possible processes used for cheating can be blocked before testing. In order to monitor the screen of many students in real time, effective compression of the captured original image is important. We applied three-step compression methods: initial image compression, resolution reduction, and re-compression. Through this, the original image of about 6MB was converted into the storage image of about 3.8KB. We use the process extraction and management functions of Windows API to block the processes that may be used for cheating. The CBT system of this paper with the new security enhancement methods shows the superiority through comparison of the security related functions with the existing CBT systems.
