  • The science teachers' perceptions and the status of formative assessment in science teaching were identified through a questionnaire. The majority of teachers thought that the most important goal of assessment in education was to identify to what extent pupils achieved learning objectives. They suggested that formative assessment was the most appropriate method regardless of the purposes of assessment. They thought that formative assessment was an assessment carried out at the end of lesson to identify to what extent pupils achieved learning objectives. The teachers stressed the need for formative assessment to identify what pupils achieved. But they carried out formative assessment about once a week and there were very few teachers carrying out formative assessment during the lesson. They responded that it was difficult to carry out formative assessment because of large class size, lack of time and difficulty in preparation. And they used the information from formative assessment to judge the level of attainment.

  • The purpose of this study is to examine whether and how the features of performance assessments implemented during integrated science classes are related to teachers' PCK. We observed and video recorded four high school teachers' performance assessment practices, interviewed them, and surveyed their PCK. An analysis of the data shows that the teachers' performance assessment practices differed in terms of assessment of process, diagnosis of student learning progress, feedback, degree of classroom interactions, and use of assessment criteria. In particular, the opportunities for students to participate in assessment actively and use of assessment for learning varied across teachers. Also, relational patterns among science teaching orientations, PCK and performance assessment practices were found. When a teacher aimed at teaching for both academic learning and scientific literacy, sophisticated PCK was shown and assessment practices were complex accordingly. When scientific literacy was emphasized PCK highlighted experiential learning and assessments were not clearly distinguished from learning activities. In contrast, when academic achievement was emphasized traditional teaching strategies and assessments were highlighted. Based on these findings a number of topics for professional development are suggested including strategies for students' active engagement in assessment, use and development of specific assessment criteria, strategies for assessing performance qualities, and intuitive assessment competency development. Further research topics are also suggested.

  • Performance assessment was introduced to improvement of self-directed learning and method of assessment for differenced learning as the seventh educational curriculum is enforced. Performance assessment is overcoming limitation about problem solving ability and higher thinking abilities assessment that is problem of a written examination and get into the spotlight by way for quality of class and school normalization. But performance assessment has problems about possibilities of assessment fault by appraisal, fairness, reliability, and validity of grading, ambiguity of grading standard, difficulty about objectivity security etc. This study proposes fuzzy performance assessment system to solve problem of the conventional performance assessment. This paper presented an objective and reliable performance assessment method through fuzzy reasoning, design fuzzy membership function and define fuzzy rule analyzing factor that influence in each sacred ground of performance assessment to account principle subject. Also, performance assessment item divides by formation estimation and subject estimation and designed membership function in proposed performance assessment method. Performance assessment result that is worked through fuzzy performance assessment system can pare down burden about appraisal's fault and provide fair and reliable assessment result through grading that have correct standard and consistency to students.

  • Writing is an activity known to enhance higher level thinking. It allows the writer to utilize, apply, and actively expand the acquired knowledge. One way to increase writing activity in classroom setting is to use peer assessment. In this study, we sought to increase the accuracy of peer assessment by having students discuss about the scoring rubric or by referring to an expert's assessment. One hundred and fifty college students participated in the experiment. In the group that referred to the expert's assessment, the accuracy of peer assessment increased when the same piece of writing was evaluated; however, no such increase was observed when another piece of writing was assessed. On the other hand, in the group that discussed about the scoring rubric, the accuracy of peer assessment remained the same when the same piece of writing was evaluated, but increased when another piece of writing was assessed. Also, in the discussion group, the accuracy increased in proportion to the number of comments during the discussion. The results suggest that active and voluntary participation of students increase the accuracy of peer assessment.

  • 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.
