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.

This study is to verify the effects of classes at a finishing stage using cartoons depicting certain science textbook units on scientific attitudes and academic achievements of students, compared to those of classes using experiment and observation oriented textbooks. Participants of this study were 56 fifth graders at B Elementary School in Busan, and cartoon textbooks were developed based on 'Unit 1. Mirror & Lens' and 'Unit 3. Temperature & Wind' from a science textbook for the 1st semester, the year 5 to conduct cartoon led lessons just before ending a class till the 10th lesson, for the period of 4 weeks. The result of this study can be summarized as follows: Firstly, scientific attitudes improved better from the cartoon based lesson of a final stage than from the experiment and observation method, and especially more effective in lower groups among all other academic achievement levels as well as in male students. Secondly, academic achievements scored higher when cartoons were used in lessons than when the experiment and observation type was used, with higher groups of academic achievement levels working better, despite no significant gap existing between two genders. Thirdly, the memory transfer and sustenance of lessons were more effective in finishing class stage with cartoon studies than with experiment and observation one, and among all levels and both sexes, higher academic groups and male pupils exceeded. Fourthly, when questioned about their opinions on a cartoon led lesson for a final stage, 65% of those participants responded positively, while higher groups preferred more than lower groups. responded positively, while higher groups preferred more than lower groups.

Students' emotional attitude not only affects their achievement in a meaningful way but also is an important educational goal in its own right. This research investigated how students' interest in science varies among elementary, middle and high-school students based on a survey and reviews of previous research results. We analyzed students learning attitude in terms of interest in and enjoyment of science, instrumental motivation in science, science learning anxiety, and self-concept in science. Major findings are students showed more negative attitudes in intrinsic motivation, instrumental motivation, value perception of science, and confidence in science as they move in to a higher school level. According to students' explanation, science classes got bored in a higher grade because of difficult contents, lack of experiments and activities, and teachers' monotonous explanations. Based on the results, recommendations on how to improve students' attitudes towards science are suggested. First of all we need to secure more science instructional hours in the school curriculum than the 7th national curriculum to implement improved science teaching and learning methods.

This work describes a preliminary investigation to a learning model based on cybernetics and radical constructivism. To achieve this purpose, main ideas of cybernetics, i.e., negative feedback, difference, self-regulation, equilibrium, and purpose-directed behavior was analysed under radical constructivism. Powers' model, which consists of hierarchically arranged negative feedback systems, is introduced into this work. This was based on the claim that living organisms behave to control perceptions. By adding the notion of scheme from the view of radical constructivism, a learning procedure, which consists of six steps, was suggested in this work.

In this study, we investigate the effects of instruction using science magic program on the scientific attitude and scientific inquiry ability in elementary students. For this study, it was chosen two classes of the forth grades J elementary school in Seoul. Instruction using science magic program was applied to the experimental group for 8 weeks during the school hours. The results of this study were as follows : 1. Science tasks applied science magic had influence on elementary learners' scientific attitude in positive way. 2. Science tasks applied science magic had valuable significance to observation, classification, data intepretation ability. However it had no valuable significance to scientific integrated inquiry.

The purpose of this study was to investigate the effect of science journal writing on science-related attitude and science academic achievement of elementary school students in order to find out the value of science journal writing. For this purpose, one class of 6th graders was tested. The result of this study were as follows: First, Science journal are classfied by forms and content. The most frequently used types are prose and organizing concept. Second, Science journal writing brought positive effects on science - related attitude, especially cognition of science. Third, Science journal writing has positive effect on science academic achievement. Therefore Science Journal Writing can be useful method in Science education.

The purpose of this study is to examine the effects which applies teaching program that search solution to prevent global warming in middle school gifted class. This program of total 10 class was theoretical and experimental class and the students presented after collecting the synthetic data about climate-change and roleplayed what they debated to firm their country's opinion about Kyoto Protocol. Finally, students as policymaker made mock Kyoto Protocol by discussion. Impression papers and images about climate-changes was made by students in last class. In discussion of making up mock Kyoto Protocol, developed and developing nations had an argument about carbon dioxide emissions because of their economic benefits. In the course of allocating mutual $CO_2$ reduction, they needed yield and negotiation among nations. Although they mainly took passive position about $CO_2$ reduction, atmosphere that all the country make greater effort for the future global environment was formed. Like this, students had more concepts over climate change by making mock Kyoto Protocol. And they could equipped global scientific literacy and responsibility by participating in social decision making process of solving global environmental issues.

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.
