The purpose of this study is to examine the effects of an free inquiry method based on PBL(Problem-Based Learning: PBL) to improve students science process skills and self-directed learning characteristics. To verify this research, twenty-two third-grade students were selected from Chung-ryeol Elementary School located in Busan. They have received pre-test and post-test about their abilities in their science process skills and abilities for self-directed learning characteristics. Also, their self-reflection data was analyzed. The teaching and learning PBL process is to provide the information named 'I am the expert on Earth and Moon' which is recreated by analyzing the science curriculum and characteristics of students from Lesson 3 'Earth and Moon', and to make plans for solving the information with K/NK method. Then, to solve the information is gathered and investigated using the PBL workbook. Lastly, students present their finding using the free inquiry method in a group. The post-test showed following results : first, the free inquiry method based on PBL stimulates inquisitiveness in students about science learning and the research group shows improved science process skill. It shows us that using the free inquiry method based on PBL can be used effects to elevate science process skill. Second, the free inquiry method based on PBL has a positive effect on self-directed learning. The research tells us that using the free inquiry method based on PBL can improve a student self-directed learning characteristics.

Problem-based learning (PBL) is an effective teaching-learning strategy for enhancing students' motivation, problem solving ability, and creativity. Its educational values coincide with the aim of open-inquiry activity introduced in 2007 revised national curriculum. From this aspect we designed the PBL open-inquiry program and implemented to 202 first year middle school students in Gyeonggi provincial office of education for one semester. We developed an energy related PBL problem. The program was designed in four steps: 'understand the problem,' 'investigate information,' 'solve the problem,' and 'present and evaluate the result.' Through the program, students did such activities as 'make Know/need to know chart,' 'group discussion,' 'search information,' and 'preparation of group report.' After completing the program, a survey was conducted to understand the students' perception of the program. The results are as follows: First, 40.6% of students showed positive attitude toward the program. Especially, students responded that 'make Know/need to know chart' was very useful. However, some students responded that 'search information' and 'preparation of group report' were difficult to perform. Second, male students showed positive attitude toward the PBL program compared to female students. Also students had higher scores in attitude toward science, showed more positive attitude toward the PBL program. Third, there was a significant correlation between attitude toward science and perception of PBL steps. Based on survey results, some suggestions were made for teachers who were planning to implement PBL in open-inquiry program.

The purpose of this study is to device the teaching-learning method and the evaluating method on 'free inquiry' which is newly introduced in 2007 revised curriculum. The teaching-learning models which apply 'free inquiry' are 'group investigation', 'PBL', 'project investigation' and 'IIM'. And the unit which apply 'free inquiry' on the fourth grade and the second semester in the elementary science. The results of this study are as follows: First, The person leading the lesson is not a teacher but learners. The focus of teaching-learning is not a unit but topic, problem or project on the science textbook. A teacher's role is not the deliverer of knowledge but the guide of learning. Second, the outcome of applying group investigation, PBL project investigation and IIM to 'free inquiry' is improvements of the problem-solving ability and the self-directed learning ability as well as building scientific attitude and social skills as educational effect in commonly. Third, to apply 'free inquiry' efficiently, teachers should understand each subject very well, teach a class with a thorough and concrete plan, and try to evaluate objectively.

The study applied a narrative inquiry to the undergraduate interdisciplinary course taught for three years(2012~2014). Narratively I have described interactions among teachers' and students' performing the interdisciplinary consilience course with various situations such as place, curriculum and class interaction. I have specifically illuminated a three-dimensional narrative inquiry space embracing the dilemma of the consilience curriculum, PBL(Problem Based Learning) and TBL(Team Based Learning), and an effective presentation. The result of the study is as follows: First, the ratio of giving lecture is high. The burden of doing project will be reduce if the teacher decreases the lecture up to one fourth, gives students enough time to finish their tasks, and gives them advice for a better project. Second, for opening the interdisciplinary consilience class maintaining previous college curriculum, each department has to put a 'consilience course' on the existing curriculum that allows teachers open the consilience course whenever they need to teach with other department teachers. Third, an effective teaching method using the PBL(Problem Based Learning) in Team Based Learning environment is making students to consider projects as problem situations to solve and to apply the problem situations to PBL method. Lastly, teachers should give students lots of opportunities for presenting what they have learned in the class. Three times of presentation as a team member is ideal in a semester but the way of presenting has to be changed. The students in next year will relieve the tension of 30 minute instead of 15 minute, two days instead of one day for the team presentation.

This study aimed to develop an e-PBL program for high school students using COVID-19 related data and to investigate the impact of the developed program on students' science core competencies. For this, the e-PBL program was developed in consideration of the characteristics of learners and e-PBL, and a science core competency analysis framework. The program was applied to 26 general high school life science club students. Test for science department core competency was conducted before and after class by questionnaires and their conversation data during class was collected and analyzed by the framework. As a result of the study, the developed program was effective in improving five science core competencies. In the results of the analysis of the science core competency questionnaire, there were significant effects on scientific thinking ability, scientific inquiry ability and scientific problem solving ability. Unlike in the results of the questionnaires, the five sciences department core competencies appeared evenly in student discourse analysis. Among them, scientific communication ability and scientific participation and lifelong learning ability did not show significant results in the questionnaire, but in the discourse analysis results. Both abilities were the most evenly displayed competencies through the program stages. Through the study, we expect that the program is possibles to be useful instructional material to make high school students increase science core competencies.
