Students' learning processes and mathematical levels should be correctly diagnosed in many different methods of assessment to help students learn mathematics. The study developed the model for the process-based assessment while using manipulatives in the middle school in order to improve problem solving, reasoning and communication which are emphasized in 2009 reformed curriculum as the areas of mathematical process. Identifying the principles of assessment, we created the assessment model for each area and carried out a preliminary study. Based on this, we revised the representative items and the observation checklist and then conducted a main study. Through the results of assessment, we found that students' thinking processes were well presented in scoring rubric for their responses on each item. It meant that the purpose of the assessment as a criterion-referenced test was achieved.

The purpose of this study is to investigate how middle school mathematics teachers understand the definition and the purpose of constructed-response assessments as well as what they expect from the assessments. By examining the responses of 189 middle school mathematics teachers to the survey, we found that there is discrepancy between their perceptions and reality of the constructed-response assessments in practice. In other words, teachers' practice is not well aligned with their perceptions and expectations due to the restraint of school system and environment. The findings give us some meaningful implication for the improvement of effective constructed-response assessments and professional development.

The purpose of this study was to analyze the reliability and validity of CDT as a screening tool for cognitive impairment for stroke clients living in local community. Two evaluator assessed 51 clients' cognitive function using CDT and K-MMSE from October 2010 to August 2011 year. The researcher analyzed test-retest reliability, interrater reliability, construct validity, construct validity. The test-retest and interrater reliability was higher than .54(p<.01). The construct validity and concurrent validity was statistically significant(p<.01). So, The CDT using productive method and scoring system of Freedman et al., may be applied to screen cognitive impairment of clients with stroke.

In today's secondary school mathematics curriculum, assessment is to be focused on evaluating the student's mathematical thinking rather than finding the correct solution to the problem. A descriptive evaluation method is therefore introduced to the school districts and suggested as an alternative assessment method in K-12 school mathematics. Descriptive evaluation method is widely available for use in schools, but there are barriers to using it since the teachers are forced to use the method by the school districts. In this research, we surveyed 120 secondary school mathematics teachers in Seoul and the surrounding metropolitan area to understand the status and the perception about using descriptive evaluation. The goal of the study was to find and understand the direct implications of using the new assessment method in secondary mathematics classes. The study showed that most of the mathematics teachers used the descriptive assessment method during their regular exam periods which is given twice per semester. Most of the open-ended problems used for descriptive evaluation were medium or high level math questions which were graded by the teachers at least 3 times to ensure objective evaluation. The teachers stated that objectivity in grading, administrative situation, and development of descriptive problems were the difficult barriers in descriptive evaluation. The teachers in the survey also commented that teachers' administrative responsibility should be reduced and that school environment in general should be improved for the new assessment method to become successful. Finally, the study showed that development of more descriptive problems with specific grading guidelines need to be developed for each grade level.

현재 초.중.고등학교 현장에서 시행하고 있는 학력평가 방법은 일률적이고 획일화되어 있어, 학생의 학업성취도를 구체적으로 제시하기 힘들다. 이를 해결하기 위한 한 방법은 과목 영역별로 평가 단위를 낮추고, 이를 바탕으로 통합된 평가 결과를 제시하는 것이다. 본 연구에서는 학업성취도를 효율적으로 평가, 분석, 관리하는 시스템을 설계하고 구현하였다. 시험 채점 결과의 입력으로부터 다양한 분석 결과의 제공에 이르는 전 과정이 편리한 인터페이스를 통해 처리된다. 이는 또한 대형 데이터를 신속하게 처리할 수 있는 성능면에서 확장성있는 시스템이다.

자동 쓰기 평가 연구는 쓰기 답안지를 채점하는데 드는 시간과 비용을 절감할 수 있어, 교육 분야에서 큰 관심을 가지고 있다. 본 연구의 목적은 쓰기 답안지의 문서 구조를 효과적으로 학습하여 평가하고, 문장단위의 피드백을 제공하는데 있다. 그 방법으로는 문장 레벨에서 한국어 Sentence-BERT 모델을 활용하여 각 문장을 임베딩하고, LSTM 어텐션 모델을 활용하여 문서 레벨에서 임베딩 문장을 모델링한다. '한국어 쓰기 텍스트-점수 구간 데이터'를 활용하여 해당 모델의 성능 평가를 진행하였으며, 다양한 KoBERT 기반 모델과 비교 평가를 통해 제안하는 모델의 방법론이 효과적임을 입증하였다.

This study tried to develop an test tool of social workers' ethical sensitivity(SWEST) on base of realization about the importance of ethical sensitivity of social worker who are required more ethicalities than the other professionals. Nevertheless, there has been no tool that can measure ethical sensitivity of social workers in our country up to now. Through analysis of existing ethical sensitivity tests in other professions, a paper and pencil method about unstructured question with cases including ethical issues and structured scoring system was chosen as an appropriate method for the SWEST. This study progressed in order : 1st collecting cases, 2nd composing cases, 3rd consulting cases, 4th pilot study, 5th making scoring standards, 6th determining case examples and scoring standards. With the result, the tool consists of 3 case examples with ethical issues : 1) self-determination and confidentiality, 2) equality and double relationship, 3) informed consent and conflict interest. And ethical sensitivities of social work major students and social workers were measured with the SWEST, to see practical utility of this test. The agreement degrees between two independent raters were above 90%. And respondent's ethical sensitivity displayed the most definite difference according to taking or not taking a course 'Social work values and ethics'. Through these results, it can be drawn that the SWEST is reliable and valid to test relevant differences in Korean social workers' ethical sensitivity. The SWEST is expected to activate studying, educating, and practicing ethics in social work.

The purpose of the study was to show the development process of the total instructional alignment based on the 2015 revised technology home economics curriculum, and to present the detailed aspects of this task. The results of this study were as follows: First, the clarity phase of the performance established the annual evaluation plan to ensure the consistency of the achievement standard, the learning objectives and the assessment objectives through an analysis of the curriculum. Second, the development phase of the performance tasks and the grading criteria analyzed the contents area and determined the performance assessment task. The performance assessment consisted of a portfolio and project activity types, and also comprised of knowledge markets, as well as e-NIE tasks, including individual tasks and collective tasks. Third, the performance assessment and the results phase were conducted after planning the class operation according to the instructors' directions and arrangement of the schedule into block classes. Afterwards, the performance assessment tasks were revised by the teaching-learning community and class reflection on practical application. As these results demonstrate, developing performance tasks that are centered on the learner's development processes can contribute to teachers' expertise and improvement of instruction.
