The purpose of this study was to investigate inquiry-based science instruction developed and implemented by a pre-service chemistry teacher regarding the difficulties that she encountered and the ways how she tried to solve out problems. Main data of this study were pre-service teacher reflections that were written after developing both each lesson plan and the whole 10 lesson plans, and after implementing both each lesson and the whole classes. Supplemental data were lesson plans, class audio recordings, and student written journals. The pre-service teacher learned that she was lack of science content knowledge and understanding of students’ understandings. Also she had difficulties of developing inquiry-based science lesson plans, managing classrooms, and guiding students to engage in science inquiry. In order to overcome the difficulties, she asked for advice to experienced teachers, studied science concepts using textbooks and internet resources, provided detailed and concrete guidance for student argumentation and writing.

The purpose of this study is to investigate the effects of portfolio instruction on the creativity and scientific inquiry ability of 6th-grade students in science classroom. Four classes were sampled from an urban elementary school in southern part of Seoul. Two classes were assigned to experimental group and the other two classes to control group. Portfolio instruction was administered to the experimental group for 10 weeks, and traditional instruction to the control group. Data on students' creativity and scientific inquiry ability were collected prior to and after the treatment for both groups. Students' perception on portfolio instruction was investigated with experimental group after the treatment. The results of this study are as follows: (1) Portfolio instruction had a significant positive effect on creativity; (2) Students' originality, one of sub-domain of creativity, showed marked increase after portfolio instruction; (3) Portfolio instruction had a significant positive effect on scientific inquiry ability; (4) Integrated inquiry ability, a sub-domain of inquiry ability, improved meaningfully after portfolio instruction; and (4) Students' perception on portfolio instruction is very positive.
The purpose of this study was to analyze the characteristics and changes in epistemic thinking when an argument-based inquiry science class was applied in no face-to-face and face-to-face situations. Participants of this study were 113 8th grade students of four classes from a coed educational middle school in a metropolitan city. Data collection was made over one semester during which ten argument-based inquiry science lessons on five subjects were conducted in both no face-to-face and face-to-face context. As a result of comparing and analyzing students' epistemic thinking in the argumentation of each group's generating question stage, the no face-to-face classes showed higher understanding of contents and more evidence suggestion validity than face-to-face classes did. Claim validity and categories of process in argumentation were higher in face-to-face classes than No face-to-face classes. Students were able to improve their understanding of knowledge through writing by discussing rather than direct communication in no face-to-face situations, and in face-to-face situations, students showed that their thoughts were influenced by interpersonal relationships with the group members.
The purpose of this study is to investigate the effects of problem-solving inquiry teaching using concept sketches on conceptual changes about plate tectonics and science-related attitudes. The subjects of this study were two classes of second-year students of K high school located at Anseong in Gyeonggi Province. Before instruction, a conceptual test was conducted to survey student's preconceptions about plate tectonics. The control group took a traditional lesson, while the experimental group was applied to problem-solving inquiry teaching using concept sketches. After the inquiry instruction, TOSRA (Test of Science-Related Attitudes) was administered to find out changes in science-related attitudes of the two groups. The results of this study are as follows. The experimental group understood concepts of plate tectonics better than the control group, which means that problem-solving inquiry teaching using concept sketches was more effective in students' conceptual understanding. Science-related attitudes of the experimental group showed a significant change in the categories of 'normality of scientists', 'pleasure of science lessons', and 'interests on science as a hobby'. In conclusion, the instruction of problem-solving inquiry using concept sketches produced students' positive changes in conceptual understanding about plate tectonics and science-related attitudes.

Despite the continuing emphasis on the importance of scientific inquiry, research studies have commented that authentic scientific inquiry is not implemented in school science classroom due to a lack of understanding of scientific inquiry by the teacher. The purpose of this study is to investigate understanding of scientific inquiry developed by beginning teachers through open-ended questionnaire and semi-structured interview. They voluntarily set up the goal of inquiry-based classes, planned inquiry-based classes, shared and reflected their teaching experience in professional learning community for more than a year. It appeared that participant teachers understood scientific inquiry as 'what scientists do', 'process how students do science' and 'science teaching methods.' All teacher participants described scientific inquiry as 'what scientists do', and understood 'the process of doing scientific investigation to solve problems related to natural phenomenon' and 'the process of constructing scientific knowledge using scientific practice.' Two participant teachers seemed to understand scientific inquiry as a 'teaching method' based on the understanding of the process how scientists or students do science. Participant teachers had a limited understanding of scientific inquiry that it is the same as laboratory works or hands-on activities prior to engaging the professional learning community, but they developed an understanding of scientific inquiry that there are various ways to conduct scientific inquiry after engaging in professional learning community.

We developed the novel coursework of 'NIE community activity teaching-learning plan' in the unit of 'Clothing Life' of the 7th 'Technology-Home Economics' curriculum and applied it to classes in the middle school. The educational themes of 'Textile and Cloth', 'Purchase, Usage and Storage of Clothes', 'Laundry of Clothes', Recycling and Disposal of Clothes' were extracted from ten kinds of textbooks. And eight lessons of NIE community activity teaching-learning plan were developed. Ninety-seven students at second grade in 3 classes of the middle school were randomly enrolled in this study. After learning, their environmental recognition and educational interest and attitude on the class of NIE community activity were investigated. The general environmental recognition of most students was improved via NIE community activity, which is emphasizing on the analysis of articles of newspapers, the critical and creative thinking, and the mutual discussion. The environmental recognition related to 'Textile and Cloth', 'Purchase, Usage and Storage of Clothes', 'Laundry of Clothes', Recycling and Disposal of Clothes' was significantly improved. Educational interest and attitude on the class of NIE community activity were also improved of great significance. The novel contents and methods of NIE community activity were evaluated to help students understand the class better and enhance their environmental recognition higher. With these results, NIE community activity teaching-learning plan might not only improve the educational interest and attitude, but also enhance the environmental recognition of the students.
The purpose of this study is to investigate the effects of research project activities using the science writing heuristic on science inquiry abilities and attitudes toward science in high school students. For this purpose, we conducted the research project activities using the science writing heuristic consisting of questioning, experimental design, observation, argument and evidence, reading, and reflection steps for 73 students of the second year of science core course in high school in Jeonnam. In order to analyze the effects of the program, we surveyed the scientific inquiry ability and attitude toward science, investigated the perception of the research project class applying science writing heuristic, and conducted interviews when there was difficulty in interpreting the results. And the results of this study are as follows. First, among the science inquiry abilities, the score of Reasoning, Hypothesis setting, Finding variables, Operational definition, Experimental design, Graphing and data interpretation, Generalization was significantly improved statistically (p<.05), but the score of Expectation was not statistically significant (p>.05). Second, among the attitudes toward science, the score of 'Leisure interest in science', 'Enjoyment of science lessons', 'Career interest in science' was significantly improved statistically (p<.05). And the score of 'Attitude to scientific inquiry' decreased but it's not significant statistically. The high school research project applying science writing heuristic had a positive effect on scientific inquiry ability and scientific attitude but it could be burden to students because it is led by students in a form different from general science class for a long time. And so continuous study on research project that minimize these disadvantages and maximize their merits is needed.

The purpose of this study was to investigate the change in beginning science teachers' inquiry-oriented teaching practice through mentoring program. Participants in this study are three mentor teachers and three beginning teachers. The three beginning teachers are middle school science teachers who have less than four years teaching experience. Also three science teachers participated in the program as mentors, who have more than twelve years teaching experience. We collected data such as video recordings of beginning teachers' classes, lesson plans, recordings of one to one mentoring and RTOP class observation reports. Mentor teachers observed and analyzed five classes of each beginning teacher. Before the mentoring program, beginning teachers' teaching methods were more concept-oriented and teacheroriented. They rarely used inquiry-elements including prediction, reasoning, hypothesizing and students were not actively engaged in communicative interactions in a classroom. But during the mentoring program, these teachers recognized and responded to student diversity and encouraged all students to participate in science learning. Beginning teachers' teaching methods have changed to become student-oriented, teachers and students collaborated in pursuit of ideas, and students often initiated new activities relevant to an inquiry. As a result, this mentoring program provided beginning teachers the opportunities to reflect on their own teaching and reform their classes. The results show that school-centered mentoring program is helpful to enhance beginning science teachers' inquiry-oriented teaching ability.

This study aims to explore how to characterize high school science inquiry. For this research, data were collected from fifteen science classes (18 hours), through observation and videotaping, interviews with a few students and their teacher, and documents such as lesson plan or activity sheet in 13 Science Core High Schools. All the data were transcribed and analyzed. Analyses of these transcripts were proceeded in three steps: first, classroom cases showing active interactions between teacher-students and among students were selected; second, according to cognitive process of inquiry (Chinn & Malhotra, 2002), each segment was analyzed and interpreted; lastly, distinctive cases were determined to show essential features of school science inquiry. Based on the analyses, we characterize high school science inquiry in terms of features of variables controlling-device improvement, design studies, evidence-explanation transformation, and reasoning to formulate explanations from evidence. Teachers' role and educational support were discussed as well as the practical characters or features of school science inquiry.
