정보 교육에서 수업과 평가를 통합하는 과정지향적인 평가가 수시로 이루어지기 위해서는 평가자인 교사가 보다 편리한 방법으로 평가를 할 수 있게 지원해 주는 사용성(Usability)이 고려된 웹기반평가시스템이 필요하다. 본 연구에서는 기존의 웹기반평가시스템의 사용성 요소를 분석한 후, 오프라인 지필평가과정에 내재한 사용성 요소를 추출하여 사용성이 제고된 PBA(Paper-Based Assessment) 평가 모델을 제안하였다. PBA 모델에 의한 웹기반 평가시스템은 교사주도하에 평가전, 평가중, 평가후의 모든 과정이 제어된다. 특히 평가 대상을 손쉽게 바꿀 수 있고, 평가지에 대한 접근을 평가 단계마다 철저히 차단시켜 평가 결과에 대한 신뢰성을 높일 수 있다. 또한 학생들은 자신들의 학년, 반, 번호, 이름을 사용하여 손쉽게 평가지에 로그인할 수 있다. 본 논문에서는 이와같은 PBA 모델에 기초하여 정보교육용 웹기반평가시스템 PAS(PBA-based Assessment System)를 설계 및 구현하였다.

This paper proposes a Web Based Online Outage Cost Assessment and Information System(WOOCAIS) for power system outage cost assessment. The proposed WOOCAIS is a kind of web based survey method for outage cost assessment. While conventional survey methods have done outage cost assessment based on survey paper lists collected by post mail or visiting customers, the proposed WOOCAIS is a web based online survey operation and assessment system. Therefore, it can curtail expenditure for survey and also is more convenient than conventional method. It will be set up for actual outage cost assessment system of KEPCO in South Korea in the near future. The WOOCAIS will be applied in various research and actual planning and operation areas. First of all, the assessed results may be not only applied as one of objective function for generation system and grid expansion but also operational planning problems in power system.

This paper addressed various issues related to the objectivity of student assessment in medical education. The objectivity of assessment was related to all the steps of test development, administration, and results reporting in terms of reliability and validity. Specifically, the objectivity of item formats, representativeness of test content, standardization of test administration, consistency of scoring procedures, and appropriateness of reporting test results were discussed by comparing performance assessment with traditional paper-and-pencil tests. The conclusions were derived from current measurement theories such as standards-based assessment, evidencebased design, and outcome-based assessment. Further, based on Shepard's propositions (2006), the objectivity of student assessment could be achieved by improving the concordance between educational objectives and assessment components such as item types, test contents, and test administration, scoring, and reporting.

The purpose of this study was to develop the assessment tools using graphing calculators for the assessment of the mathematical process which was emphasized in 2009 reformed mathematics curriculum. In this paper, we presented three sample calculator-based test items for the assessment of students' mathematical process abilities and scoring rubrics for the paper and pencil assessment and assessment based on observation on each item. In order to improve mathematics teachers' understanding of the assessment tools using graphing calculators and to show the procedures of assessment using technological devices, we also drew up assessment guidelines. We hope the results of the study contribute to the promotion of assessment environment encouraging the use of graphing calculators in assessments.

교사의 평가 전문성의 영역 중에서도 평가 문항 제작 능력은 평가의 타당도, 신뢰도에 있어 필수적인 요소이다. 다시 말해, 평가문항의 내용적인 측면과 형식적인 측면에서의 오류는 올바른 평가를 저해하는 요소이며 이러한 평가를 통하여 긍정적 피드백이 이루어질 수 없다. 본 연구는 서울 경기 인천 일반고등학교 45개교 수학과 중간고사와 기말고사 기하와 벡터 60개 시험지의 문항 분석을 통하여 지필평가의 내용적인 측면과 형식적인 측면에서의 문항 오류와 개선점에 대하여 논하고, 이를 통하여 교사들의 평가 문항 제작에 대한 능력 제고를 그 목적으로 하고 있다.

Assessment and rehabilitation of patients with unilateral visual neglect has been one of the fields that require assistive technology. Paper-and-pencil tests, including the LBT (Line Bisection Test), have been one of the most commonly used visual neglect assessment methods used in a clinical setting. The key motivation of this study was to establish a computer-based real-time assessment system for the hemi-neglect patients without altering the conventional paper-and-pencil based user tools. A digital penbased assessment and rehabilitation system, the ePen System, could eliminate the manual assessment time while maintaining measurement accuracy. As a result, the proposed system may assist rehabilitation specialists to assess and diagnose patients with unilateral visual neglect. This system can be applied to a range assessment and rehabilitation modalities based on a pen and paper. It can also be applied to various patients such as those with Parkinson's disease, stroke sufferers, or those who have experienced different forms of brain lesions.

This paper deals with a voltage sag assessment based on a voltage monitoring program. The voltage sag performance at a specific site can be evaluated by analyzing voltage monitoring data recorded for a long time period. Although an assessment based on voltage monitoring is an effective way to understand voltage sag performance at a measurement site, the statistical confidence of voltage sag frequency estimation heavily depends on the length of monitoring period and the number of recorded events. Short monitoring period and insufficient recorded data can not provide a reliable assessment result. This paper proposes a compensation assessment method by combining a computer simulation approach for in case that monitoring period and data are not enough for a valid assessment.

본 연구는 국제 학업성취도 평가인 TIMSS 2019 사전검사에서 지필 평가와 컴퓨터 기반 평가로 시행된 과학 평가 문항을 분석하여 검사 매체에 따라 문항 정답률에 영향을 미치는지를 문항 및 학년별로 살펴보았다. 그 결과, 4학년과 8학년 모두 검사 매체에 따른 과학과 문항 정답률 차이가 크지 않았다. 학년별로 살펴보면, 8학년보다는 4학년의 경우 정답률 차이가 상대적으로 크게 나타났다. 문항별로 살펴보면, 선다형 문항보다는 서답형 문항의 경우 정답률 차이가 상대적으로 크게 나타났다. 검사 매체 영향에 대한 과학과 평가 문항 내용을 분석한 결과로는 선다형 문항은 지필 평가와 컴퓨터 기반 평가 문항간의 차이가 거의 없었으나, 서답형 문항은 지필 평가에 비해 서답형 문항의 정답률이 낮아지는 경향을 보였다. 또한, 학년별로는 4학년 학생들이 8학년 학생들보다 서답형 문항에서 정답률이 낮아지는 것으로 나타났다. 본 연구를 토대로, 우리나라 컴퓨터 기반 평가의 개발과 현장 도입과 관련된 시사점을 제공하고 컴퓨터 기반 평가가 학교 평가로 잘 정착하기 위한 교육적 함의를 고찰하고자 한다.

Capstone design is a subject taught in a setting where students gather in a team, decide on their own selected topic, and collaborate with one another to perform a project. A fair assessment is very important in a team project-based capstone design course for students. Many instructors agree that harmonizing creative evaluation and outcome assessment is hard in capstone design class. In also, it is not easy to assess students' individual efforts and achievements fairly in accordance with team-based assessment practices. To resolve this issue in this paper, we have surveyed various engineering design education methodologies, and have modelled existing evaluating elements into a modified creative process and outcome assessment framework for team project assessment. In particular, we focused on a method of fairly assigning credits by combining team based and individual-level assessments. Analyzing students' achievement and grade evaluation and verifying the validity of the proposed method was performed.

Capital project benchmarking requires an effective cost normalization process to compare cost performance of projects accomplished in different time and location. Existing cost normalization approaches have been established based on the assumption that all required information for cost normalization is fully identified once a project is completed. Cost normalization, however, is sometimes required to evaluate phase-level outcomes of an ongoing project where the required information is not fully available. This paper aims to provide a cost normalization procedure for phase-based performance assessment. The procedure consists of three normalization steps: currency conversion, location adjustment, and time adjustment considering various scenarios where the required information is not fully identified. This paper also presents how the cost normalization procedure has been applied to the 10-10 Performance Assessment Program, which is a phase-based performance assessment system developed by the Construction Industry Institute (CII). Both researchers and industrial professionals can apply the cost normalization procedure to studies and practices regarding to cost estimation, feasibility analysis, and performance assessment.
