In this study, we investigated the influences of the epistemological beliefs on the conceptual change processes in respects of cognitive conflict, situational interest, attention and state learning strategies. After administering epistemological belief questionnaire as a pretest, 218 seventh graders possessing misconceptions about density were selected from the results of a preconception test. The questionnaires of responses to a discrepant event and situational interest were administered. After learning with a CAI program, attention test, state learning strategy test and conception test were also administered as post-tests. Analysis of the results revealed that fixed ability, quick learning and certain knowledge, which are epistemological factors, were highly related, but only certain knowledge exerted a direct effect on conceptual understanding negatively. It also had positive effects on attention directly as well as via situational interest, and thus increased conceptual understanding, even if the effects were relatively smaller than the direct effect. However, epistemological beliefs had little influence on conceptual understanding through cognitive conflict and/or state learning strategies.

The purpose of this study was to develop learning materials for the discussion and examine the effects of the discussion learning over the students' conceptual change on force and motion. The subjects consisted of 360 middle school students, comprising of 5 discussion groups of 185 students and 5 traditional learning groups of 175 students. The results indicated that students in the discussion groups showed higher achievement than those in the traditional learning groups. Therefore this study supported the importance of discussion in conceptual change. However further research should be conducted to examine other educational effects of discussion.

The purpose of this study is to explore the relationship between selected components of conceptual ecology that are reflected in high school science students' statements, when answering questions. This study follows from a position that there is reason to believe that, in the process of answering questions, many aspects of conceptual ecology are likely to play a role. Data were gathered through six audio-taped interviews, the science teacher's profiles of each student, the students' personal journals, their assignments, and their examinations and participation in class. Kay and KY were selected as the focus of this study because theirs were both dramatic as well as representative cases. As the findings suggest, learning styles differ according to distinctions within individuals' conceptual ecologies. Thus the way in which a person learns science varies according to the construction of her/his conceptual ecology. This suggests that different forms of pedagogy may be effective with different types of learners. This also suggests that science educators may have a role in assisting students to develop into constructed, rather than received, learners.

The purposes of this study are to investigate the effects of the Science Conceptual Model Completion Activity and Science Conceptual Model Modifying Activity on middle-school students' achievement in science conceptual learning, and to analyze if there are any correlations among their achievements by purposed activities, their cognitive level and school science achievement. For the study, 112 middle school students were sampled for three groups, which are two experimental groups (Model Completion activity group, Model Modifying Activity group) and one control group. Pre- and post-tests were taken to measure the students' achievement in science concepts, and the logical thinking ability test was administered after the implementation period. In addition, their school science achievements were analyzed. The research findings are as follows: First, the Science Conceptual Model Completion activity is more effective for middle school students' science conceptual learning than the Science Conceptual Model Modifying activity or conventional activity. Second, higher school science achievement also results in higher achievement of science concepts through the Conceptual Model Modifying activity or the Conceptual Model Completion activity. Lastly, the Conceptual Model Completion activity is more effective for the concrete operational level students to attain science concepts than formal operational level ones. Meanwhile, on the contrary, the Conceptual Model Modifying activity is more effective for formal operational level students than the concrete operational level ones.

This study explored a possibility of science concept learning in scientific practice-based science instruction through the review of literature about situated learning theories and practice-based science education. It was revealed that the situated learning theories were closely related to the recent trend in science education which emphasizes students' active engagement in scientific practices. From the perspective of situated learning, concept learning occurs in the process in which learners make use of concepts as resources and further develop the concepts through the emergence of conceptual agency during their participation in practices. The study also found that the situated learning perspectives could apply to science concept learning in scientific practice-based instruction: Science concepts are used as resources in practice-based science learning, students can better engage in scientific practices as they take advantage of science concepts as resources, and the emergence of conceptual agency can facilitate science concept learning during the participation in scientific practices. Implications for school science education were suggested.

In this study, we investigated the influences of cognitive conflict and situational interest induced by a discrepant event and an alternative hypothesis, attention and state learning strategies on conceptual change. A preconception test was administered to 486 seventh graders. They also completed the questionnaires of cognitive response and situational interest to a discrepant event before/after presenting an alternative hypothesis. After learning the concept of density with a CAI program as conceptual change intervention, the tests of attention, state learning strategies, and conceptual understanding were administered as posttests. Analyses of the results for 197 students having misconceptions about density revealed that post-cognitive conflict was significantly higher than pre-cognitive conflict. However, there was no statistically significant difference between the test scores of pre-situational interest and post-situational interest. Pre-cognitive conflict only exerted a direct effect on post-cognitive conflict, while post-cognitive conflict exerted a direct effect and Journal of the Korean Chemical Society an indirect effect via attention on conceptual understanding. Both pre- and post-situational interests were found to influence on conceptual understanding via attention. Attention had influences positively on deep learning strategy and negatively on surface learning strategy. There was a relatively small effect of state learning strategies on conceptual understanding.

There are so many research literatures on conceptual change theory and the nature of concepts such as p-prims, mental model, ontological belief, and cognitive structure. Conceptual change means learning (Vosniadou, 1999; Duit;1999). It is necessary to review and elaborate existing conceptual change theories in order to explain the learning process and its implications. Therefore, we derived from reviewing literatures that learners construct new conceptual structure in response to given contexts at the same time activating their beliefs. We reviewed some mental theories that integrated cognitive and affective components and were based on framework/specific theory or information processing theory. We suggest learners' framework of conceptual structure and conflict model of conceptual structure. We expect to obtain effective ways of science teaching and learning and implications for cognitive conflict and conceptual change from using conceptual structure later.

In this study, some issues that are related to embody the original conception and ideal of action learning are explored in terms of misunderstanding and misuse of action learning in Korean corporate context. The conception of action learning is deconstructed through the lens of 'action' and 'learning' concept, followed by conceptual analysis to the nature of 'action' and 'learning'. Based upon this conceptual deconstruction of 'action' and 'learning', this study is conducted to categorize the concept of 'action' and 'learning' into several representative attributes. Categorization of 'action' and 'learning' leads to draw some adjectives, for examples, reflective, dynamic, complex, nonlinear, that are critical for characterizing action learning. That is, the nature and ideal of action learning are critically reviewed with the reconceptualization of 'action' and learning, which are deconstructed. The Discussion of final thoughts is on what kinds of knowledge perspectives action learning holds in comparison with those of knowledge management and on how to facilitate knowledge construction and sharing with action learning.

This study investigated the effects of cooperative learning environments in conceptual change instruction upon students' conception, achievement, learning motivation, attitude toward science instruction, and perception of involvement. Two classes of 8th graders at a co-ed middle school were assigned to the treatment and the comparison groups. They were taught about density, boiling point, freezing point, and solubility for 11 class hours. The treatment group's learning environment involved cooperative conceptual change instructions while the comparison group's environment incorporated individual conceptual change instructions. Mann-Whitney test results revealed that the scores of the conception and achievement test for the treatment group were significantly higher than those for the comparison group. The perceptions of involvement for the treatment group were more positive than those for the comparison group. The scores of the learning motivation test for the treatment group were found to be significantly higher than those for the comparison group based on a two-way ANCOVA analysis. However, attitudes toward science instruction were not found to be significantly different between the two groups.

This qualitative study investigated two preservice teachers' conceptual ecologies in professional development during the science teacher preparation program. The notion of a conceptual ecology contains nature of knowledge, science and science teaching, learning, and content knowledge and comfort level. The data were collected during the participants' preservice year and their practicum experience. Both data collections and analyzing were from the various sources of interviews, teaching observations, journals, and information and profiles by the participants' supervisor. Two preservice teachers serve as cases representative of this study. Results show that problems preventing the preservice teachers from moving closer to conceptual change teaching were their understandings of the nature of science and the nature of knowledge. The preservice teachers' views about knowledge come from, and what knowledge is, are largely shaped by the nature of science and learning drive pedagogy and classroom practice. Knowledge of and comfort with the subject matter are also important.
