This study primary aim is to investigate students' responses to experimental results which conflict with their preconceptions regarding electrical circuits. Eighty-eight students of both sexes were randomly selected from a science high school in Korea. They were questioned about their preconceptions regarding an electric circuit, and sixty-eight students with relevant misconceptions were selected. These students were presented with experimental results obtained by some other experimenter, and asked to interpret these results. The second aim of this study is to explore how students' responses vary according to the type of inquiry-skills required to obtain the result. To do this, two type of experimental results were developed: one obtained by observation and the other obtained by controlling variables. We found that many students doubted results for the simple reason that they conflicted with their preconceptions. They rejected results by mentioning other factors which could have affected the result, or simply by reiterating their preconceptions. This behaviour varied considerably by inquiry-skill type. 41% of students rejected conflictual result obtained by observation, but only 6% of students rejected results obtained by controlling variables.

Many science teaching models have been devised and published for the students' conceptual change by researchers. However, the science teachers have been confused with so many models to be used in teaching science. Since the models are composed of ambiguous statements, it seems to be difficult for the teachers to understand their characteristics and natures. Therefore, the models were difficult to be adopted in science instructions. In this study, the researcher developed two checklists which were devised especially for the teachers who apply the Cognitive Conflict Process Model (the Procedural Teaching Model using Cognitive Conflict Strategy) in Science Concept Instruction. One is for planning instructions using the model, the other is for examining or analysing them. Each of them consisted of 20 items and 33 items, respectively. Using these checklists, the Cognitive Conflict Process Model can be checked whether it was applied properly in actual instruction or not.

The purpose of this study was to analyze relationships among science achievement, science process skills and affective perception of high school students. The affective perception was included attitude toward science and science anxiety in the study. The instruments were developed HARS and SAMS for this study. The subject was sampled 1,115 students by stratified cluster sampling method. The major findings of this study were as follows: The tendency to affective perception was investigated according to students variables. Atittude toward science was showed a negative perception on female than male, in rural area than city. Science anxiety was percepted highly on female than male, in rural area than city. Attitude toward science showed positive relations to science process skills, science achievement, but which showed negative relation to science anxiety. Science anxiety showed negative relations among science process skills, science achievement and attitude toward science. Structural relationships among affective perception, science process skills and science achievement were analyzed by effect size through the path analysis on the independent and dependent variables. By the results, it was indicated that there have significant direct effect not only affective perception influence on science achievement but also on science process skills in hypothesized model. Prediction of science achievement and science process skills were clarified to characteristics of the affective perception.Therefore, understanding about affective perception will be helpful to make the strategy of science teaching

Journal of The Korean Association For Science Education, volume 16, issue 3, 1996, Pages 270~277
The purpose of this study is to classify and state of evaluating objectives using three-dimensional assessment framework of science inquiry. The first, as an attempt to provide a theoretical base for developing an assessment framework taxonomies and classificatory schemes of educational objectives were analyzed Bloom's taxonomy, Klopfer's specification, NAEP(National Assessment of Educational Progress), and APU(Assessment of Performance Unit) framework. The second, three-dimensional assessment framework use in this study has formed a clear definition of three-dimensional matrix. These three dimensions consists of content, context and process. The third, the model of three-dimensional taxonomy of science inquiry developed in this study is presented. In addition, an example of classification and statement of evaluating objectives based on the model is presented.

High school students' achievements in algorithmic problems, and figure-formatted and textual-formatted conceptual problems concerning stoichiometry, gaseous state, and solution, were measured by the Chemistry Problem Solving Ability Test. The relationships among the achievement scores in the three types of problems and cognitive variables such as logical thinking ability, mental capacity, and field dependence/field independence were examined. The portion of variance of explanation for each achievement score was also studied by a multiple regression analysis. The results showed that logical thinking ability was significantly correlated with the achievement score in the algorithmic problems, and accounted for the significant portion of the variance of the score. Mental capacity accounted for the significant portion of the variance of the score in the figure-formatted conceptual problems. Although field dependence/field independence was significantly correlated with all the achievement scores, it did not significantly account for any scores in multiple regression analyses. However, the magnitudes of correlation coefficients among the achievement scores were higher than those between the achievement scores and cognitive variables. The best predictor for each score was also found to be one of the other achievement scores. Educational implications are discussed.

In this study, the image of scientists and the self-image in terms of stereotypical masculine and feminine characteristics were investigated for 562 primary and secondary school students. The perceived differences between the image of scientists and the self-image were quantified and compared across grade levels and gender. Their relationships with science-related attitudes were also studied. The results indicated that students hold more masculine characteristics in the image of scientists and more feminine characteristics in the self-image. The perceived differences between the image of scientists and the self-image were greater for female students than male students. Female students also had more negative attitudes than male students on Career Interest in Science and Enjoyment of Science Lesson of the Test of Science-Related Attitudes. It was found that the differences between the perceived images were negatively correlated with science-related attitudes. Although the relationships were found to be statistically significant, the magnitudes were relatively small. Educational implications are discussed.

The purpose of this study was to investigate the effects of training and use of worked-example on chemical problem-solving learning. Schema acquisition and rule automation are the basic components of skilled problem-solving, which are dependent on appropriately focused attention and sufficient cognitive resources. Training and use of worked-example facilitate schema acquisition and rule automation, so improve problem-solving learning. The subjects of this study were 60 high school students. The average age was 17 years old. Then, they were randomly assigned to each groups and the chemical reaction problems used as experimental materials. The independent variables of this study were training and use of worked-examples and dependent variables were time for solution and the number of error. The results of this study were as follows; 1. The worked-example groups spent significantly less time on solution for acquisition problems than the conventional problem groups. 2. The long-acquisition groups spent significantly less time on solution for acquisition problems than the short-acquisition groups. 3. The modified worked-example groups did not spend significantly less time on solution for acquisition problems than the worked-example groups.

The major purpose of this thesis is to construct the evaluating framework of a science textbook with a high confidence and universal validity, referring to a preceeding study and materials involved in research work, and in consideration of the educational conditions of the secondary school. The framework developed in this study are composed of 7 categories: content, organization, representation, laboratory, illustrations, external form or editing system, and supplementary materials. Each category consists of detailed items. Eech item in the check-list is to be given between one and five points, and the total number of possible points in this evaluating framework is 290. As a result, these evaluating items enable quantitative analyses, afford an opportunity which we can look into many-sidedly the respects we should consider when a science textbook is adopted, and they can be estimated partly or synthetically as occasional demands. This study is exepected to contribute to choose a good science textbook as fundamental data in the future, and to help the lasting study or estimation of the textbook.

This study investigated the literature about science process skills' evaluation to analyse transition of evaluation objectives before and after a Scholastic Ability Test for College Entrance. In the literature survey the researcher established a 3 dimensional science assessment framework with X axis as science concept, Y axis as science process skills and Z axis as problem context. In order to analysis and compare each items the researcher selected 210 items from the 1st to the 7th trials and 138 items from the 1st to 4th Scholastic Ability Test for College Entrance and sampled 2873 science achievement test items from 10 high schools. In accordance with this taxonomy the researcher analysed and compared science process skills item forms. The following results were drawn : The items were evenly distributed in all the four areas(Earth Science, Biology, Physics and Chemistry) of the science concept domain, but they were heavily concentrated on data analysis and drawing a conclusion in science process domain. In the domain of problem context school context was the majority. In spite of distribution like this the ratio on science process skills measurement items and science achievement test items was increased after the Scholastic Ability Test for College Entrance was given. Also the ratio on item expression type was increased. Item form was almost 5 options selection type in the national level test. Although there were 4 options selection type, 5 options selection type, short answer type, essay type in school level test, rising from 33.1% to 65.5% on 5 options selection type is exhibited. This study showed that the school level item form was better various than the nation level. This point like this is the evidence for the improvement toward the science process skills test and influenced by Scholastic Ability Test for College Entrance. The ratio on the item which joined with the 3 axes had a mean of 99.3% in nation level test and mean 44.9% in school achievement test level. But the ratio in the school achievement test level increased after the Scholastic Ability Test for College Entrance was given. In view of this study we must furthermore study the item types which can evaluate valjdately science process skill's five stage each and evaluation method by the high school students' problem solving patterns and features in scientific inquiry on all science process skills elements.
