  • Since the late of 1960,s, the improvement of science inquiry skills has been one of the most important goals in secondary science education. To achieve this goal, it is essential to develop a valid and reliable instrument for evaluating science inquiry skills. The purpose of this study is to develop a valid and reliable instrument for evaluating science inquiry skills for high school students. The instrument is developed through R & D procedure, which includes two field trials of the instrument. This study has formed a clear definition of the elements of science inquiry skills (formulating a hypothesis, controlling variables, designing an experiment, numeric calculation, graphing experimental data, inference, determining relationship, determining causalities, predicting experimental results , drawing a conclusion, formulating a generalization or model), and established the goals of assessment and developed the items of assessment. The instrument, Test of Earth Science Inquiry Skills, consists of 33 items which measure 11 science inquiry skills. There are content-free items for each science inquiry skills. This study has selected 11 science inquiry skills which are considered appropriate for being evaluated by paper-and-pencil test with SIEI (Hur,1984). The content validity of items, objectivity of the scoring keys and clarity of the items were checked by six experienced specialists in science education. At the same time, the two field trials has been executed and produced the reliability of the instrument, item difficulty index, and the effectiveness of distracters. The first field trial was performed using a sample of 304 high school students, and the second one using a sample of 872 high school students. Because the content validity is 84 % and the reliability (K-R 20) is 0.84, the developed instrument in this study is considered valid and reliable. The difficulty index is 49.4 %, answer ratio 59.1 %, the discrimination index 0.47 and the effectiveness of distracters evenly distributed, which also suffice the criteria of good instrument. The developed instrument in this study can diagnosis the well-developed science inquiry skills and the ill-developed science inquiry skills of the students, and trace the degree of the improvement of science inquiry skills.

  • The purpose for this study is to check if research activities can make positive effects on inquiry instruction utilizing materials when compared to traditional instruction utilizing the textbook. The effects of the class should be measured both in cognitive domain and in affective domain. The cognitive domain was measured by the change in achievements in learning science, and the affective domain was measured by the change in learning attitudes of science. The assumptions to be verified in this study were as follows. First, achievements in learning science are higher in the learner oriented inquiry instruction utilizing materials than in the learner oriented traditional instruction utilizing the textbook. Second, learning attitudes of science are higher in the learner oriented inquiry instruction utilizing materials than in the learner oriented traditional instruction utilizing the textbook.The results of the research are as follows. In the cognitive domain, achievements in learning science showed significant change(p=.045) measured by verifying the score for the difference among the averages for each sub-scale, in 5% of meaningful probability, and were higher in the inquiry instruction utilizing materials study. In the affective domain, learning attitudes of science showed significant change(p=.019) measured by verifying the score for the difference among the averages for each sub-scale, in 5% of meaningful probability, and were higher in the inquiry instruction utilizing materials study. In learning attitudes of science, 2 items(self-conception of science, attitudes of learning science) out of 3 items(self-conception of science, attitudes of learning science, learning habits of science) showed significant changes (p=.045, p=.001). But the difference(learning-habits of science) was not significant(p=.914).

  • The purpose of this study is to find out the effect of hypothesis formulations using abduction on science processing skills and the creative thinking activities. As the subject, 2 classes in the $6^{th}$ grade of B elementary school located in Busan were selected. Through the pre/post inspection design between experiment and comparison class, the units of science courses in the second semester of $6^{th}$ grade '1. A change in the weather' and '2. Various gases' were applied. The results were as follows: Firstly, the test on science processing skills showed that there was not statistic meaningful differences between the two groups. And, in the sub-parts, there was not statistic meaningful differences between the two groups. Secondly, it was observed that it would have a meaningful effect to improve the creative thinking activities of students who performed hypothesis formulation using abduction. Especially, through this, the experimental class gave a positive effect on the 'Fluency' and 'Elaboration', one of lower categories of the creative activities. The results of 'Flexibility' and 'Originality' in the experimental class were higher than those of students in the comparative class. However, according to statistical analysis, this result is meaningless. Thirdly, on the survey about the hypothesis formulation using abduction, many students thought that this learning method was very interesting and helpful to study science. In addition, it was observed that the ability to use abduct thinking was improved more than ever before.

  • The purpose of this study is to use DARTs (Directed Activities Related to text) to foster inquiry problems while actively engaging accelerated gifted elementary students in the field of earth sciences. This study is continually evolving in the classroom on the proposition that accelerate the scientific thought whether inquiry problems show any change according to the extent of prior background knowledge through DARTs. Researchers appointed the accelerated gifted elementary students with 14 investigation problems and it was their duty to not only classify the inquiry problems, but to analyze using interviewing methods according to type classification framework. Many scientific terms were used concretely in the inquiry problems that were propose after DART. The students gave a direct effect to the inquiry problem to be proposed according to the level of the content that it is presented in the DARTs worksheet. As a result, the NP-IP type and the EC-IP, NC-IP inquiry problem type proposed above much as a whole in DARTs former and prior. Particularly, the EMC-IP type and etc. was variously proposed after the DARTs. And the students proposing the inquiry problem of above average proposed the inquiry problem of the EP-IP type much unlike the general average student after the DARTs. The EC-IP, NC-IP and NF-IP type were changed much after DARTs used. Particularly, the EC-IP and NC-IP type were changed much.

  • The purpose of this study was to find the relationship between elementary school teachers' beliefs of inquiry and science performance assessment. To collect data for analyzing elementary school teachers' beliefs of inquiry and their practice of science performance assessment, the researcher was surveyed with elementary school teachers by open-ended questionnaires and interview. The findings of this study were as follows; First, Most of elementary school teachers beliefs of inquiry was shown as constructivist tendency. This view of inquiry involves watching and doing experiments, and the skills of thinking processes, in which learners make their own interpretations rather than merely acquiring preexisting knowledge structures. Second, for content knowledge, participants' preception about the target of science performance assessment involved assessing application of science knowledge rather than basic level of substantive knowledge. For inquiry process, participants' preception about the target of science performance assessment involved assessing the lower level of inquiry rather than the higher level of inquiry. Most of participants was measured using a paper and pencil test for the actual evaluation methods due to the ease and objectivity of the assessment, the lack of understanding how to perform the performance evaluation process and method. Especially, participants who recognize that the higher level of inquiry was used performance and informal mode of assessing.
