  • In this paper, we study inquiry tendency in informatics textbooks for middle school students. These textbooks were written in accordance with 2009 revised national curriculum, and were adopted in schools starting from 2013. Romey analysis was implemented to analyze inquiry tendency in six textbooks using four different criteria-text, data, activity, evaluation. The results showed that some textbooks displayed a low level of inquiry tendency, lacking participation from students and employing an authoritative tone. Among four factors, the 'activity' displayed the highest degree of inquiry tendency while the 'text' retained the lowest level of inquiry tendency. The Romey measures in some sections were zero, thereby indicating room for improvement.

  • The 2015 revised science curriculum and NGSS (Next Generation Science Standard) suggest computational thinking as an inquiry skill or competency. Particularly, concern in computational thinking has increased since the Ministry of Education has required software education since 2014. However, there is still insufficient discussion on how to integrate computational thinking in science education. Therefore, this study aims to prepare a way to integrate computational thinking elements into scientific inquiry by analyzing the related literature. In order to achieve this goal, we summarized various definitions of the elements of computational thinking and analyzed general problem solving process and scientific inquiry process to develop and suggest the model. We also considered integrated problem solving cases from the computer science field and summarized the elements of the Computational Thinking-Scientific Inquiry (CT-SI) model. We asked scientists to explain their research process based on the elements. Based on these explanations from the scientists, we developed 'Problem-finding' CT-SI model and 'Problem solving' CT-SI model. These two models were reviewed by scientists. 'Problem-finding' model is relevant for selecting information and analyzing problems in the theoretical research. 'Problem solving' is suitable for engineering problem solving process using a general research process and engineering design. In addition, two teachers evaluated whether these models could be used in the secondary school curriculum. The models we developed in this study linked with the scientific inquiry and this will help enhance the practices of 'collecting, analyzing and interpreting data,' 'use of mathematical thinking and computer' suggested in the 2015 revised curriculum.

  • This paper analyzed the improvement of cognitive level of the students and interactions which occurred in each step of free-topic scientific inquiry to help science teachers understand free-topic scientific inquiry better. Free-topic scientific inquiry is helpful to students with a deep strategic learning goal orientation type or a deep strategic ability goal orientation type in their transition (2B/3A) of cognitive levels. Most students have difficulties in the phase of establishing topics and hypotheses. The result says that the discussion techniques are improved through free-topic scientific inquiry, but the quality of interaction is not easily improved. The deep strategic learning goal orientation type concretizes opinion through interaction in free-topic scientific inquiry. The deep strategic ability goal orientation type are actively involve in the interaction, but they pay no attention to the process because they stick to the result. The surface strategic ability goal orientation type can not deepen a discussion due to high frequency of low level inquiry. However, the frequency of high level inquiry increases through free topic scientific inquiry operation. As a result, the characteristics of free-topic scientific inquiry were discussed and the educational implications of the progress of free-topic scientific inquiry and the organization of grouping were drawn.

  • This study is the subsequent study that has the objectives examining the relationships among 'substantive understanding', 'scientific literacy' and 'learning intention' in computer supported intentional learning environments and inquiry ability, variables for affecting knowledge construction derived from the finding out of the former study. As a result, the current study confirmed in CSILE the close correlation between 'the learning intention for scientific inquiry' and 'substantive understanding', between 'the learning intention for scientific inquiry' and 'scientific literacy'. Another result showed that 'scientific literacy' was the most significant predictor on inquiry ability. Base on the result of this study, the present researcher is about to make suggestions to stimulate learners' scientific literacy in CSILE-based inquiry learning.

  • The purpose of the study was to suggest the characteristics and goals of the science teaching model for use as criteria in selecting the appropriate teaching model for science in secondary schools. These characteristics and the goals have been organized based on the analyses of the literature on the teaching and/or instructional model. The teaching models have been classified into four areas, and the characteristics and goals of each area have been summarized as follows: $\cdot$ Traditional models: teaching of scientific knowledge through lectures, acquisition of scientific knowledge through discovery, acquisition of inquiry process skills through inquiry-based teaching/learning $\cdot$ Transitional models: demonstration and discovery as teaching strategies, acquisition of inquiry process skills through inquiry approach, acquisition and change of scientific knowledge $\cdot$ Modernistic model - conceptual change models: differentiation of scientific knowledge, exchange of misconceptions for scientific concepts - learning cycle models: conceptual differentiation, exchange of misconceptions, acquisition of science process skills Also described in this paper are the model's characteristics and goals that can be used as the criteria for selecting the appropriate teaching model for the subject that will be taught.

  • This study aims to explore the characteristics of student inquiry found in project-based science practices. The participants were four high school students in a science research club and worked their own project for one semester. During the project, they made their research questions, planned and executed their research procedures, and made their own conclusion. Their activities during the project were videotaped and recorded. They were also interviewed. Group worksheets and written reports were all collected for analyses. The whole processes of the inquiry were analyzed and interpreted qualitatively. The characteristics of student inquiry were presented in the view of the theory-evidence-method coordination. Three different modes of the coordinations that were found recursively in their inquiry were the theory-evidence coordination, the evidence-method coordination, and the theory-evidence-method coordination. It was also revealed that students' tacit knowledge using various tools were exhibited and these skills improved during their group works. The implications for school science inquiry education and research based on this study are discussed.

  • Inquiry-based experiments provide opportunities to understand scientific knowledge and acquire nature of science. In this study, the difficulties which pre-service teachers experienced in inquiry-based experiment class were investigated and analyzed. Twenty-two pre-service teachers attended course designed as ‘ill-structured inquiry’ for 13 weeks, and researchers investigated their difficulties by questionnaires and interview. They showed difficulties mostly in designing experiment and interpretation and also in understanding inquiry purpose, lack of prior knowledge, confidence in inquiry performance, and understanding of experimental instruments and facilities. As a result, it is necessary to provide opportunities to engage in inquiries and environments to properly instruct pre-service teachers the inquiry ability in college of education.

  • The purpose of this study is to estimate the ability of inquiry performance for students gifted in science in elementary school. 56 sixth graders were included in this study. Initially, a question 'How does the dust effect on human health?' was posed to students. Then, an assessment framework for analysis of the inquiry report was developed. It is composed of 5 domains: data collection, prediction, the inquiry process, results, conclusion and presentation. The findings reveal that the students achieved high scores in the domain of 'data collection' and followed by prediction, inquiry process, results, conclusion and presentation. The results of our study are as follows : first, in spite of high scores obtained in basic inquiries such as data collection, students needed to improve their skills in prediction, the inquiry process, results, conclusion and presentation. Second, the reason why students were outstanding in data collection is that they have improved their ability to handle data in a know-ledge-based information society. Third, even though students were good at citing and applying some information, they didn't fully understand the meaning of data and exhibited weaknesses in arguing their own opinions.

  • In this study, we investigated actual cases of assessment science teachers conducted and the cases they preferred in a typical situation based on the curriculum in the context of 'Scientific Inquiries in the History' of Scientific Inquiry Experiment. A questionnaire composed of descriptive questions was developed and a survey was conducted with 70 science teachers with experience in teaching 'Scientific Inquiries in History'. Interviews were conducted with eight of them. The assessment cases were analyzed in terms of the assessment areas and assessment methods, and the results were compared. The analyses of the results revealed that 'scientific inquiry ability' accounted for the highest ratio of the assessment areas in the actual cases of assessment. There were few cases that assessed the core concepts presented in the curriculum, 'the nature of science' and 'scientists' inquiry methods'. The assessment methods were greatly biased toward the report method and various assessment methods were not used. In preferred cases of assessment, the ratio of cases that assessed the core concept increased slightly, however the frequencies remained at a low. As for the assessment methods in preferred cases of assessment, the measurement methods decreased, the performance methods increased, and the informal methods which were not shown in the actual cases appeared. However various assessment methods were still not used. The causes of the survey results were analyzed based on the opinions of the teachers who participated in the interviews. Based on above results, plans to actively conduct NOS assessments in Scientific Inquiry Experiment are discussed.
