This study was conducted on four 11^th grade students at a high school in a small town to determine the effectiveness of responsive teaching. The three phases of the responsive teaching method proposed in the previous study were subdivided into six stages; Step 1 is elicitation of students' thoughts related to macroscopic world, Step 2 is drawing of students' early thoughts related to microscopic world, Step 3 is disciplinary connections with ideas of the particle, Step 4 is to clarify the learner's thoughts on the particle by the teacher's involvement, Step 5 is deepening students' thoughts, and Step 6 is expanding ideas. In Step 4, students came to the recognition that the cause of mass was atoms and that the cause of volume was molecules. In Step 5, students led to a shift in thinking that could ignore the volume of the molecules themselves through the properties of protons and neutrons that affect mass from a particle perspective. In the Step 6 of expanding ideas, students explained molecular motion by the concept of material point which ignores the volume of particles. This steps gave students perspectives on the relationship between the mass and volume of particles required by Avogadro's law. The students recognized that some systems could be studied only indirectly because they were too small, too large, too fast, or too slow to observe directly.

The Great Learning is an essential scripture of Confucianism that has had great influence on the politics, thoughts, society and culture of the East Asia which contains Korea, Japan and China. In case of Japan, the doctrine of Toegye(退溪) is flown into pre-Tokugawa era, and as the doctrine of Zhu Xi(朱熹) exercise influences over the other thoughts, the importance of the Great Learning is embossed relatively in Tokugawa era. The characteristic of Japanese confucianism of Tokugawa era is to lay weight on real world as such, and the Japanese confucianism has grown up academically centers on exhaustive reinterpretation about some Confucian classics. And Backho-Yoon Hyu(白湖 尹?), Seokye-Park Sedang(西溪 朴世堂) who lived in 17th century of Joseon dynasty attempt new interpretation about the Great Learning and they have an objection to the explanatory notes of Zhu Xi. In the same period of China, there are similar academic trends around Whang Jong Hi(黃宗羲), Ko Yeom Mu(顧炎武), Wang Fu Chi(王夫之). In other words, new views of real scholarship which reject emptiness and put much value on reality were current of thoughts that have been common to the oriental three countries in early and middle 17th century. The main object of this paper is to understand the attitude and understanding about the Confucian classics especially the Great Learning of the scholars who lived in early and middle Tokugawa era. It will be a decisive clue to understand the ninucture of thoughts system of them. Through these work, we understand how it has had influenced to thinking-ninucture and lives of the Japanese. And the other purpose of this paper is to understand characteristics of them when we compare that vking-ninucture and lives of the Japanese Confuciang-ninearly and middle Tokugawa era with in the same period of Jeseon and the later Ming(明) and early Ching(淸) dynasty.

Researches about the Horaknonjaeng(湖洛論爭) have succeeded by focusing on the Osangnonbyeon(五常論辨)?Mibalnonbyeon(未發論辨). In a way of these researches, philosophic thought of Gwon Sangha(權尙夏) is dealt in a comparison and in that process his philosophic thought seems to be known. However, these researches are treating several thoughts so it is difficult to find accurately what point describes the position of his thought in the korean confucian thought as origin of Hohak(湖學). In this paper, therefore, I examine Gwon Sangha's theory of mind-nature by focusing on the understanding the concept of mind-nature in Hansujaejib(寒水齋集) and find its position in history of thought as an origin of forming Hohak. Before 1709, Horaknonjaeng don't break out, Gwan Sangha had been formed that Inmulseongsangi(人物性相異) of Osangpyeonjeon(五常偏全) based on the understanding of the fact that ensuring of Bonyeonjiseong(本然之性 性善) in Gijiljiseong(氣質之性) and under this influence scholars of Hohak formed thoughts and insisted Osangpyeonjeon(五常偏全 人物性相異) during Horaknonjaeng. In the point of Simseongilmul(心性一物) focusing on nature, he didn't admit the Jujaeseong(主宰性) of mind. This is the efforts of finishing the controversy of Simseongigi(心性二岐) and the efforts of finding the relation between Simseon(心善). Such thoughts are set before the Horaknonjaeng and basing on these influences, scholars of Hohak formed their thoughts and insisted the Gibulyongsa(氣不用事 未發氣質有善惡).

This study examines the ways in which Confucianism developed in connection with other thoughts. Mythology especially had an great impact on the formation of Confucian thoughts. This study focuses on the concept of sage and examines how Confucianism and mythological thoughts influenced on formation and reformation of the concepts. In ancient religion, sages as a hierophantic figure, mediates human beings and gods, delivering the gods' messages to the human and the human's wishes to the gods. The fused role of shaman and ruler began to separate. A new type of leader without political power, but with a religious role with a moral authority is the Confucian concept of sage. A sage in Confucianism is an ideal person like Confucius, Mencius, and Xunzi, an ordinary person can attain with effort. Anyone can become a sage in Confucianism. The early Confucian sage was more like a hyper-human with unaccessible authority in mythology. Later, a sage in Confucianism began to be described as a model figure that any human being can become. The aspect of shamans and diviners (wushi 巫師) did not disappear, but merged into a kingly power and transformed into a sage-king with moral authority. The new images are reflected in Confucian ideology of statehood or its religiosity. This study has explored the ways in which Confucianism and mythological thoughts interacted and influenced to each other through a concept of sage as an ideal personhood.

This research shows that Mozi setting forth a military thoughts will be discussed and lighted up in modern value. Mozi's theory on a military was formed in order to protect weak people from the strong in the basis of his philosophy of not attacking. It is different from the art of war for attack. There are some merits in Mozi's strategy of war that we have to take notice of. First of all, Mozi indicated that married women, the old and children was provided with specific roles in the war times. Especially, married women' parts will be equal to men. The old and children should usually be respected for the government to offer them important roles in the war time. Therefore, this paper will be showed in the respect of Mozi's thoughts that is considered as human being's fundamental rights in terms of ensuring the weak's rights. Furthermore, Mozi's theories on technology from loving the civil was applied to defensive fight and his advanced arms was arranged in the actual fight. However, his arms could be useful to the only defensive fight. This case was reflected as Mojia's theories that science is sincerely useful toward the civil. There will be some small or large wars in the future. Mozi's theories based on a military peaceful thoughts that everyone ought to be loved without discrimination should be highly valued when all wars will take place for the purpose of their own profits.

We present the thoughts behind a course combining the subjects of differential equations and infinite series. The key point is how to connect the two topics in a course with a natural flow.

Some after-dinner thoughts on the giants of infrared space astronomy. I here describe important events in infrared astronomy starting from 1964 when I started working on my PhD. Here I describe how I became involved in IRAS, Infrared Space Observatrory (ISO), Herschel, Spitzer and AKARI, together with important events that led to these great missions.
