This is the second year study of ''The Development of Model of National Criterion- Referenced Assessment Standards" that had started in 1997. In the study, national assessment standards for high school common science were developed based on national curriculum. In the whole process of developing the standards, high school teachers, university professors and administrators of the Ministry of Education have participated as the "developing group" or "consulting group". Through various activities such as conference, workshop, intensive work, examination by science education experts, the standards and instruments were developed and modified. The research contents can be itemized as follows: - modifying the achievement standards developed in the first year research based on the opinions of various experts(science teachers, professors of science education, philosophers) - developing assessment standards based on the specially designed system. The standards divide students' achievements into three levels(upper/middle/low) and state each level so that it can guide evaluation of achievement. - developing various types of test instruments to probe students' achievement levels for each assessment standard.

The purpose of this study was to develop a valid and reliable assessment tool for measuring scientific creative problem solving ability for middle school students. To achieve this aim, an assessment framework, four assessment items, and detailed rubrics for scientific creative problem solving were developed. The assessment framework had three dimensions (i.e. science contents, inquiry process, and thinking skills) and sub-elements for each dimension. The assessment items were tested with 320 middle school students in order to determine reliability, difficulty, and item discrimination. Science teachers and experts in science education checked the validity of the items and the rubrics. The results proved that the assessment tool was reliable enough to evaluate students' scientific creative problem solving skills.

The purpose of this study is to develop the science item on computer-based performance assessment which is able to replace the assessment with actual experimental apparatus. The survey on the necessities and the difficulties of the assessment with actual experimental apparatus was conducted with 57 physics teachers. By reflecting the results of the survey, the computer-based assessment items which are related with constructing circuits with an ammeter and a voltmeter were developed. The developed computer-based assessment items were organized in similarity to assessment conducted with actual experimental apparatus, proper feedback was provided by students' performance in the process of assessment so as to grading performance results automatically. To achieve them, the algorithm was developed so that computer can judge the accuracy of students' performance results.

지금 우리과학기술계는 '목숨을 걸고 뛸 사람'이 필요하다. 목숨을 걸고 연구를 기획하고 개발해야 한다. 또 평가자도 목숨을 걸고 올바른 평가를 내려야 하며 내일의 과학한국을 위한 후진양성도 목숨을 걸고 해야한다. 먼 훗날 손자손녀가 "할아버지는 무엇을 하셨나요"라고 물으면 "목숨을 걸고 과학기술을 하여 너희들이 이처럼 번영을 누리는 것이다"라고 자랑스럽게 말할 수 있어야 하지 않겠는가.

This study investigated 15 science teachers' perception and practice on free semester and science assessment. We analyzed frequencies of teacher choice for closed questions and used constant comparative method for teacher description and individual interview. Most teachers determined a low ranking for changes in assessment methods and mentioned a lack of objectivity on free semester assessment, unsystematic free semester assessment, and more importance on student activity and interest in science instruction. Most teachers understood process-based assessment as a direction of free semester assessment and teachers mentioned positive aspects for students or teacher difficulties dependent on their perception on process-based assessment. Half of the teachers failed to implement student self-assessment and student peer-assessment due to subjectivity and complexity. Some teachers did not provide feedbacks to students due to a lack of time and did not use certain assessment methods due to a lack of knowledge of the assessment. Teachers who did not have an experience of discussions in a teacher learning community mentioned reasons regarding a small number of the same grade teachers and inactive attitude of colleagues. Teachers who did not participate in professional development programs mentioned a lack of teacher understanding of free semester, participation of the teacher in charge, and teacher choice of participation as reasons.

현재 과학과 수행평가는 교사평가가 주를 이루고 있기 때문에 평가 결과의 피드백이 신속하게 이루어지지 못하고, 동료평가가 거의 이루어지지 않는다는 문제점이 있다. 따라서 본 연구에서는 웹의 장점을 이용하여 인터넷 상의 다양한 자료를 보고서 작성에 이용할 수 있고 동료평가와 교사평가를 동시에 시행할 수 있는 웹 기반 과학 보고서 수행 평가 시스템을 설계하였다. 이 시스템의 흐름은 교사의 평가 과제 제출을 시작으로 학생들이 각자 다양한 정보를 수집하여 보고서를 작성하며 작성된 보고서를 동료 및 교사가 일정한 평가 기준에 의거하여 평가한 후, 학습자에게 평가 결과를 피드백하는 것으로 설계되었다. 이러한 시스템을 통해 교사의 업무 부담 경감은 물론, 학습자의 학습 의욕과 성취도 향상을 기대할 수 있다.

In this study, we investigated the characteristics of the pedagogical content knowledge (PCK) components and their integrations in the processes of developing performance assessment tasks of pre-service chemistry teachers who participated in the constructive performance assessment workshop. Eight pre-service teachers participated in this study. After three weeks of the constructivist performance assessment workshop, they developed their own performance assessment tasks. The think-aloud method was used to investigate their developing processes. Their activities were recorded and videotaped, and semi-structured interviews were also conducted. The analysis of the results revealed that the PCK component considered in the planning step showed similar frequencies for assessment, instructional strategies, students, and subject matter components. In the embodying step, assessment component was most frequent. In the discussion step, the frequencies for assessment, instructional strategies, and students components were similar. However, curriculum component and the subcomponent of science process skill were rarely used. The integrations among the PCK components were found to be centered on the instructional strategies component in the planning step and the students component in the embodying and discussion step. However, curriculum and subject matter components were rarely integrated with other PCK components. On the basis of the results, educational implications are discussed.

This study focused on the use of peer assessment activities to investigate its the impact on students' argumentation skills in argument-based inquiry. The participants of the study were 106 10th grade students (four classes). Two classes were assigned to the experimental group, and the other two classes were assigned to the comparative group. The experimental group was taught argument-based inquiry through the application of peer assessment activities. The comparative group was taught argument-based inquiry without peer assessments. At the claim and evidence stage, students were asked to evaluate whether peers' claims fit with the evidence and whether peers' explanation of the evidences validity was sufficient. The quality of argumentation used in the students' writing was different in each group. According to the analysis of the summary writing test, the results showed that the experimental group had a significantly higher mean score than the comparative group in argumentation components, including evidence and warrant/backing. In addition, the experimental group used better multimodal representation including explanation of evidence than the comparative group. The findings showed that argument-based inquiry applying peer assessment activities had an effect on the argumentation skills in students' writing.
