  • The purpose of this study was the identifying differences between physicists' expectations and teachers' representations about the primary physics concepts in elementary schools. For this, the material subjects analyzed were the 7th curriculum, the textbooks of elementary school and the texts using at the department of physics in many universities. The primary physics concepts extracted from the texts were to be fundamental and basic. Also, they were restricted to the domain of dynamics. And besides, the human subjects were physicists, professors and students majoring physics of the graduate school, researchers of institutes or laboratories and elementary school teachers. At the result of this study showed the scholars and teachers have the different opinions.

  • There has been disagreement on the importance of definitions in science education. Yager (1983) believes that one crisis in science education was due to the considerable emphasis upon the learning of definitions. Hobson (2004) disagrees with physics textbooks that do not provide general definition on energy. Some textbooks explain that "there is no completely satisfactory definition of energy" or they can only "struggle to define it." In general, imprecise definitions in textbooks (Bauman, 1992) and inaccuracies in definition provided by teachers (Galili & Lehavi, 2006) may cause alternative conceptions. Besides, there are at least four challenges in defining physical concepts: precision, circularity, context and completeness in knowledge. These definitional problems that have been discussed in The Feynman Lectures, may impede the learning of physical concepts. A meta-study approach is employed to examine about five hundreds journal papers that may discuss definitions in physics, problems in defining physical concepts and how they may result in alternative conceptions. These journal papers are mainly selected from journals such as American Journal of Physics, International Journal of Science Education, Journal of Research in Science Teaching, Physics Education, The Physics Teachers, and so on. There are also comparisons of definitions with definitions from textbooks, Dictionaries of Physics, and English Dictionaries. To understand the nature of alternative conception, Lee et al. (2010) have suggested a theoretical framework to describe the learning issues by synthesizing cognitive psychology and science education approaches. Taking it a step further, this study incorporates the challenges in semantics and epistemology, proposes that there are at least four variants of alternative conceptions. We may coin the term, 'alternative definitions', to refer to the commonly available definitions, which have these four problems in defining physics concepts. Based on this study, alternative definitions may result in at least four variants of alternative conceptions. Note that these four definitional problems or challenges in definitions cannot be easily resolved. Educators should be cognizant of the four variants of alternative conceptions which can arise from alternative definitions. The concepts of alternative definitions can be useful and possibly generalized to science education and beyond.

  • Most students have difficulties and negative perceptions about physics learning. Especially, it is difficult to understand the whole context by learning based on logical-scientific thinking which excludes narrative thinking. This study aims to develop a storytelling teaching-learning method using the narrative thinking in physics lessons for improving the difficulty of students of physics learning, For this purpose, a storytelling teaching-learning method that can improve scientific attitude and understand and change the concepts was developed through literature research. The following results were confirmed its effects to apply high school students and middle school students. First, the teaching-learning method using the storytelling for high school students with low interest in learning had a significant effect in science-related occupation, interest in science and science-related activities, criticism, openness, cooperation, and spontaneity. Second, the middle school students who are active in learning recognized that teaching and learning methods using storytelling helped to understand physics concepts. The storytelling teaching-learning method developed through this study is expected to stimulate students' interest and motivation in physics and to be useful for learning concepts by improving their scientific thinking skills.

  • According to many previous researches on the students' physics conceptions, in spite of school science learning the students' preconceptions were either not changed or reinforced. Although many researchers argued that the presentation of conflict situations which can not be explained by the students' preconceptions is prerequisite to their conceptual changes, some other researchers argued that such a presentation could be useless. In this study, a model of students' conceptual change in physics, which encourages students to recognize actively the conflicting situations and to control the process of their conceptual changes, was developed. In this model, the critical discussion on rival concepts and the reflective thinking were regarded as two important factors for students' conceptual changes.

  • This paper discusses the effect that classroom demonstrations have on students' conceptual understanding in concepts in introductory physics. We used the same conceptual survey to probe the students' understanding on certain concepts before and after taking the course. We introduce Hake's , which is used to evaluate the effect of various kind of teaching methods, suggested by physics education research groups, on conceptual understanding of students who took the class. The effect of physics class using demonstration turned to be better than the traditional lecture, higher for students who graduated from science schools with higher prior knowledge and demonstration experience. Authors suggest to use to probe concepts which need more attention.

  • The concern with scientific mode1s has been growing in science education, and schematic models are frequently used to teach science concepts in secondary schools. The aim of this study is to investigate how well the scientifically gifted students understand scientific concepts through activities of modifying scientific models which we developed. Thirty 8th-grade students participated in the study, 15 in a control group and 15 in an experimental group. For the students in the experimental group, teaching material with activities of modifying models, while for the students in the control group, the teaching material with traditional activities such as explanation, problem solving, and reading. The teaching contents in physics for both groups were linear momentum. We used multiple-choice test and essay-type test to evaluate students' achievements after lessons, and then compared their achievements of both groups. Through the research, we could find a clue that model-modifying activities are helpful for the gifted students to enhance their understanding of physics concepts, although the statistics does not show meaningful difference between experimental and control groups.

  • In is a recent trend of the world to study the integrated science curriculum development. This study aims at pursuing how to integrate physics and earthscience in high school course and forming a tentative plan as to an integrated process between both the subjects. The one was compared with the other accor ding to the basic concepts and theteaching objecties. The contents of these two subjects were analysed, the overlapping parts being chosen, and so in the hierachy of the curriculum, some mistakes were found in eaching these two two subjects. It proved valid to in tegrate these two subject. A concrete scheme was offered to in tegrate these two subjects-physics and earthscience, when a tentative plan concerning, the integra ted process was made. This new plan can make the time required for teaching decrease by 5% The better study on the basic structure of the integrated concepts between these two subjects will go on further in this respect. It is necessary to train again the teachres concerned with this new subject and to put an emphasis on the elective course between physics and earthscience in the teacher's college curriculum.

  • The purpose of this study is to examine the misconception profiles of the scientifically-gifted and non-gifted children in terms of basic physics concepts and to compare them in terms of the types of differences in misconception as well as in their understanding of the concepts themselves. The subjects of this study were 75 scientifically-gifted children attending the Educational Center of Gifted Children in DNUE and 148 non-gifted children in elementary schools in Daegu city. For the purposes of this study, the basic concepts of physics (heat, electromagnetism, force, and light) which should be learned in an elementary school were selected with a review of related previous research and with an analysis of the 7th science curriculum. Next, a questionnaire was made which was made up of 20 multiple choice statement based items. Analysis of the results of the statement sections in the test, it was hoped, would reveal the difference between the scientifically-gifted and the non-gifted children's understanding, while the responses in the multiple choice items would suggest the differences between the two groups in terms of the misconceptions regarding physics concepts. The results of this study are as follows: First, although both the gifted and non-gifted children showed a low level of understanding of the concepts of heat, electromagnetism, force, and light, the gifted children' level of understanding of those physics concepts was proved to be significantly higher than the non-gifted, so it seems that the scientifically-gifted children have fundamentally understood the concepts in physics and have a higher level of understanding of them. Additionally, both the scientifically-gifted and non-gifted children' level of understanding of all the concepts was lower in the order of electromagnetism, heat, force, and light. This shows that both the scientifically-gifted and the non-gifted children have no difference in the level of understanding of any specific physics concept, but have similar levels of difficulty in every concept. Second, both the scientifically-gifted and non-gifted children showed similar types of misconceptions. However, the scientifically-gifted children had fewer misconceptions than the non-gifted. We suggest that scientifically-gifted children's misconceptions were not fixed yet, so there remained a possibility of them being corrected easily with appropriate instruction.

  • In this study the concepts for science learning of physics and earth science presented in the seventh grade science textbooks for the seventh national curriculum of Korea approved by the ministry of education were analyzed in terms of the concrete and formal concept level. The parts of textbook analyzed for science learning consist of three sections in physics such as light, force, and waves, and three sections in earth science such as the structure of the earth, the substance of crust, and the movement and composition of the ocean. The analyzed results showed that the number of scientific concepts were differed from 54 to 74 in physics and from 86 to 120 in earth science depending upon publishers. In general, the concepts for science learning in the physics were found to be more in the formal level than the concrete level. However, the concepts for science learning in earth science were found to be more in the concrete level than the formal level. The analyzed results suggest that the concepts of science learning should be considered the learner's cognitive level and the sections should be disposed depending on the degree of difficulty for writing the science textbook. Therefore, it seems to be important to review carefully whether the textbook meets the object of the seventh curriculum of Korea during the process of the investigation for the science textbook.
