In this study, we investigated secondary school science teachers' actual and preferred types of assessment with focus on the purpose and the method of assessment. Participants were 92 secondary school science teachers. We developed a questionnaire asking science teachers about the types of assessment they have actually used and the preferred types of assessment for hypothetical situations that have been generally reported as the prototypical examples of constructivist assessment. The characteristics of the science teachers such as teaching career, experience on in-service training about assessment, and perspective toward constructivist assessment were also examined. The analysis of the actually implemented assessments in their responses revealed that most science teachers tended to aim at traditional purposes such as summative assessment, and that multiple-choice was the most prevailing assessment method followed by experiment, report, and essay. For hypothetical assessment situations, science teachers exhibited their preferences for various types of constructivist assessment methods, whereas their purposes of the assessment still remained to be traditional. The science teachers who have had a relatively constructivist perspective toward assessment showed a statistically significant preference for using formative assessment than their counterparts in the hypothetical assessment situations.

Constructivism has had a great influence on science education over the last two decades. The purpose of this article is twofold: First, to describe the characteristics of constructivism and, second, to suggest an ideal forms of science education in Korea as implied in constructivism. A review of the literatures in the first area shows that constructivism is philosophical/psychological view which believe in the social nature of the construction of scientific knowledge and its learning. And the analyses of a few schools of constructivism suggest decision-making as a goal of science education, learning as the active construction of meaning through interaction between learner and learning environments, and discussion and cooperation as appropriate teaching strategies. At the same time, the results necessitate teaching ethical aspects of science in the secondary schools, and also imply that performance assessment must be emphasized in evaluation of science education.

The study investigated the effect of a social constructivist model on changes of concept on 103 4th graders in three elementary schools. In particular, it analyzed whether the application of a concept circle map developed student understanding of the concept. After a one month study period, the 103 students took a pencil and paper test on changes of concepts learned. The results indicated that the social constructivist model positively influenced student concept development. In conclusion, a concept circle map used on a social constructivist model may be employed as a tool for diagnostic or formative evaluation.

The purpose of this article is to examine and assess the main issues in social constructivism with reference to the history of technology. Social constructivism, as an alternative explanation to technological change, has developed its points actively responding to various criticisms. Historians of technology have joined in dialogues with social constructivists through controversies about narrative vs theory, reliability vs performance, and evolution of bicycle. Social constructivists tend to use new jargons excessively, don't deal historical materials rigorously, and don't consider content-dependency sufficiently. To apply social constructivism to Korean cases many problems should be identified including the deficiency of historical materials, the importance of technological learning, and the peculiarity of relevant social group.

Science cultures in the dimension of social interaction must be correlated with science cultures or science literacy in the dimension of psychological interaction. In order to develop a mature science culture, it must be assumed 1) that a science culture in a society ran be evaluated and 2) that we have to set up the criteria for evaluating it. This paper, based on the assumptions, makes an attempt to analyze the concept of science literacy underlying the PISA (Programme for International Student Assessment) conducted by OECD. The analyses are driven by the questions such as 'which philosophical backgrounds are absorbed into the concept of PISA' science literacy?' and 'What suggestions can be found with respect to the goal of enhancing the science culture?' In conclusion, the science literacy in PISA reflects the elements proposed by logical empiricism, naturalized philosophy of science, and social constructivism, which are being incorporated by the 'collaboration research program' conducted by the newly-emerging interdisciplinary field of 'science of science.' Finally, some further suggestions are added to the analyses to pursue more positive directions to induce mature science cultures in our society.

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.

The biggest strength of the Internet is to enable to access information without any limitation of time and space. As the Internet and IT technologies have been developed, various kinds of teaching ways in education field such as remote lectures, video lectures, and CAI(Computer Adapted Instruction) have emerged. In terms of education, evaluation can be a basic foundation to help teach students in the next learning stage according to each student's level. In addition, it is able to give the information of students'abilities and provides proper learning programs to teach students on a case-by-case basis. The purpose of the paper is to establish evaluation system on the WWW(World Wide Web) that can reflect learning activities part of students in their evaluation scores based on the two important learning theories, Behaviorism and constructivism, which are mainly used in evaluation procedures to judge learning ability of students. This system will give information about learners, and analyze the learning interest of learners. The proposed system enables teachers to evaluate learning ability of students through various kinds of information of learners, and to execute level-based education.

This study aims to identify and evaluate the contents of ageism and to develop instrument of ageism. Ageism instrument development remains a necessary in aging research, for the explication of actual condition of ageing. The current study describes multidimensional view of ageism toward aging and the elderly. After pre-test and review of professionals, 31 items was constructed. Data were obtained from KGSS Survey of 1535 participants. The sample was randomly divided into two group to test reliability and validity of the scale. Finally, the 23-items with seven factors were suggested, based on the internal reliability and exploratory factor analysis with the first group. Another group were conducted confirmatory factor analysis. The results showed that the final 23-item scale with seven factors had a good model fit. Development and refinement of ageism scale are necessary elements for proceeding beyond theoretical and empirical discussions in ageism. It also provides a implications for current views of ageism and strategies for reducing ageism.
