The Cohen-Macaulay modules have been studied as important objects linking algebraic geometry and the module theory of algebras.
The Cohen-Macaulay modules are also a natural higher generalization of finitely generated modules over finite dimensional algebras.
I am interested in the module theory aspect of the Cohen-Macaulay module.
I am currently studying the representation type of the Cohen-Macaulay modules from its geometric structure via the functor category.

My research interests are in the origin and evolution of life on Earth in the 4.6 billion-years geological records; particularly the evolution of eukaryotes and multicellular animals. I am trying to clarify the environmental changes across these evolutions, based on the geological fieldworks in UK, China, Gabon, Mongolia, etc., the stratigraphic reconstructions (lithogy, fossils, age determination), and the paleoenvironmental reconstructions (chemical analyes). I am also developing teaching materials for geoscience education using VR technology.

I am interested in a quantum spin system where nontrivial magnetic ground states appear. To investigate those experimentally, vaious methods are utilized from static and dyanmic points of view.
By reducing the system saize some materials is weakening , and another is strengthening in magnetic properties. To learn more about the origins of those, I am conducting magnetic measurements with high sensitivity.
Experimetnal studies on hydrogen-induced phenomena are also one of my essential research activities. Also, I am carrying out the development of a new method to evaluate hydrogen absorption properties aiming at high-performance hydrogen strage.

In the future society, collaboration between leaders and followers is important.
Therefore, it is important that leaders also learn about followers and learn about followership.
The human resources that companies look for in new hires will include an element of followership.
Mastery of leadership requires that you make your own changes in your own behavior.
It is necessary to look back at one’s own behavior, notice unconscious comments and actions, and change oneself.
We are currently conducting research on building relationships with others, developing oneself, and becoming self-reliant through leadership education.

I have wide experience in teaching English in several types of schools such as junior high and high schools, including a correspondence course high school, and a university. So, in the field of English Language Education, I am interested in how to improve English language skills of EFL learners at each stage of language learning and lead them to be self-disciplined learners from the viewpoint of SLA.
In one case, learners at the higher education, e.g. university students, are required to read several literatures in order to gather information or knowledge on their interest. Some literatures may be written in Japanese, but in most cases, they are written in other languages, including English. I am investigating some possible aspects related to their effective reading, such as formal instruction, vocabulary building, background knowledge etc., and would like to identify aspects effective to reading for information gathering. These aspects may vary according to learner characteristics. In another case, I am performing studies of effective use of media such as music and movie in the language classroom.
Moreover, I would like to investigate the potentiality of BASIC English, which was “discovered” by Charles Kay Ogden, and develop educational materials for EFL/ESL Learners based on Ogden’s idea shown in BASIC English. BASIC English is a simplified and organized English brought up by Charles Kay Ogden as an international auxiliary language, and as an aid for teaching English as a second language. I think his idea is still very significant even today.

The establishment of physique (body type) and physical fitness assessment methods that consider individual growth and development is an important issue in school health. In particular, for late adolescents (high school students), who are in the final stages of their physical growth, it is important from the perspective of future health to acquire physical fitness appropriate to their physique. However, conventional physical fitness assessment often overestimates (or underestimates) physical fitness. Hence, it is necessary to develop a new evaluation method that takes individual physique into account and can be practically implemented in educational settings. In our research, we have proposed a new physique assessment (body composition category model) based on the combination of fat mass and lean body mass. In the future, we will examine the validity of this model and the evaluation of physical fitness and athletic ability by body size, verify the validity of the evaluation table, and consider applying it to the educational field.

At first, I had an keen interest in self-reflection that goes with self-narrative　(autobiography, diary and self-portray etc.), especially in its influence on personality development. To pursue this issue, I tackled researches on psychoanalysis, German expressionism and phanomenology. I also engaged in artisitic activities and created works as well.

For these years, I have been researching on philosophy of Wilhelm Dilthey, a German philosopher in 19th century, who aimed to establish humanities and social sciences as rigorous “moral science”. Recently I begin to make a study of religion and aesthetics through his works, which requires an interdisciplinary study that shows humanities and social sciences as a whole.

In the future, I hope to comprehend herumeneutics from 18th century until 20th century, which is still not clarified in Japan. Hermeneutics itself is difficult to define; it started as traditional hermeneutics in the thought of Herder, Droysen, Dilthey etc, and developed into new hermeneutics of Heidegger and Gadamar in 20th century, making idea of hermeneutics a confused one. It also had great influence on German Idealism, New Kantianism, philosophy of Nietzsche, Ricoeur, and Derrida, and psychoanalysis, which means that interdisciplinary study is necessary and essential. I can strongly feel the importance of joint study these days.

I am studying the images and movements of the learners in dance, and the teaching methods that elicited physical expression.
I am studying the image and movement in dance, such as what kind of image the learner perceives and what kind of movement appears,toward the realization of creative physical expression.
I would like to develop learning and teaching methods through exercise and sports, including dance.

My study is how to apply Individual Psychology into the field of education and clinical setting. I also study the effectiveness of Individual psychology as a movement of human welfare.

Teaching learning strategies that allow students to learn inquiringly in cooperation with their peers are attracting attention, as a learning activity that fosters 21st century academic ability, such as comprehensive inquiry time and inquiry activities for each subject that are included in the Course of Study and implemented at each school. In addition, the GIGA School Concept requires the use of ICT in such learning activities.
I am conducting research on effective teaching and learning strategies based on practical examples of inquiry-based learning, which is an educational activity required in such an era. In particular, practical training is emphasized in the Department of Informatics, and the development of learning materials and the accumulation of teaching plans are awaited so that students can acquire “information theory”, “information ethics”, “programming thinking ability”, and “practical ability to utilize information” by learning independently using ICT. Takahashi Laboratory has developed such teaching materials, analyzed practical cases, and conducted research on methods to measure the qualities and abilities of students, which is the basis for verifying their effectiveness.

We are researching the nature of science education, such as student-led lesson development and creative questioning, to nurture children who love science and teachers who can truly enjoy science classes.

〇　Researches on science classes aimed at fostering the qualities and abilities required for children to create society of the future, to face society and the world, to engage with each other, to open up their own lives, and to teachers I am doing research on training.
〇　I　am conducting research on development and evaluation of science class lessons by active learning.
〇　I am developing and researching collaborative learning support system that utilizes software and each tablet computer　that supports collaborative learning．.

The theme of this office is to research the roles of hired foreign teachers (Oyatoi Kyoshi) played in the development of Modern Japan. The rapidity of Japan’s development espacially in the Meiji Period amazed the world. One of its main factors was the focus on human resources training. Encouraging new industry, Japanese government tried by themselves to take advantage of the knowledge and skills introduced from advanced countries. They considered it important to carry out advanced education with the help of experts from those nations. How did the foreign experts try to act toward the expections?

Henry Dyer(1848-1918), pioneer of engineering education in Japan. Born in Scotland, Principal of the Inperial College of Engineering(Kobu Dai Gakko) 1873-1882. Studied the curriculum on engineering in various countries, and tried to practice education in the college.

The current society has been the era of the information-oriented society more and more. In addition, humankind is being confronted with a lot of serious issues, especially environmental problems. That’s why they have to try to solve them with the data processing and make decisions. In this sense, it is statistics education that is most important area in mathematics education in order for students to acquire literacy on the data processing and decision-making.
Hence, I focused on the development of statistics education. The objective of my research is to transform from calculus-centered mathematics education curriculum into statistics-centered one. The research methods for achieving this are to analyze and develop the curriculum. About the former, I am comparing Japan with New Zealand because Japan has to cope with globalization and internationalization from now such as New Zealand which has already had much experience on them. About the latter, I selected teaching unit (substantial learning environment) as the theoretical framework which shuttles and integrates between scholarly knowledge and craft knowledge (see Wittmann(2001)’s Figure).

I would like to make further efforts to explore more effective and useful lessons, such as the lesson style required for technical education and the discovery of new issues. In addition, as a study of manufacturing education, we will realize the joy of manufacturing, increase the motivation and enthusiasm of students and students for independent learning, and lead to more efforts, creativity, concentration and practice. I would like to explore educational methods that nurture power and have a great educational effect.

In Southwest China and Mainland Southeast Asia, many villages were known as traditional pottery making villages including glazed stoneware.
In this area, Traditional pottery making villages were maintained by ethnic minorities of each region within their traditional lifestyle.
However, in recent years, the stop and the extinction of pottery making are seen maker’s aging and the situation of successor’s absent, urgently needing gather sets of potteries to preserve real material and make records of making process and technical contents throughout this area.

[Archaeological research on early agricultural cultures in Northeast Asia]
Cultivation of rice and millet began in China in prehistoric times, and then spread to the Japanese archipelago via the Korean Peninsula. The immigration of people with agricultural techniques such as paddy fields, fields, and irrigation not only spread farming, but also changed the traditional culture of each region. We focus on the subtle differences in pottery-making techniques and research the process of migration, agricultural spread, and cultural change at the time.
[3D measurement of cultural properties]
We are researching cultural properties such as archaeological materials and museum materials using 3D measurement such as photogrammetry and X-ray CT.
[Museum curator qualification systems in Japan and Korea]
Through a comparison of museum curators and qualification systems in Japan and Korea, We are thinking about their characteristics and social and cultural backgrounds.

It is said that an increase in motivation to learn leads to effective learning in various situations, including the acquisition of a foreign language. Particularly in foreign language learning, the environment and learning experiences are closely related to learning motivation. I aim to clarify what kinds of learning experiences lead to high motivation for learning and to construct a framework for effective classes.
I am also doing research on how to incorporate reflection into teacher training programs and professional development for foreign language teachers. This will enable them to improve their own teaching practices through self-reflection and reflection with others.

I am currently conducting research on the effects of the International Baccalaureate (IB) education that is spreading in Japan.
1. I am conducting research on the effects and challenges of the IB in the context of the increasing number of high schools where students are learning mathematics in English.
2. I am conducting research on the effects and challenges of ICT utilization, which is emphasized in the IB.
3. I am conducting research on how high school teachers will change as a result of the implementation of the IB.
We are interested in how to apply the suggestions obtained from the implementation of the IB to schools in general.

In these days of drastic social change, it is difficult to predict how the future will unfold. Crime is also facing an endless number of unique crimes of lone offenders, as seen in the murder of former Prime Minister Abe, the extended suicide case in Kyoto Animation, and the murders that occur in closed rooms on trains. Such crimes cause anxiety among the public and have a significant impact on safety and security, which is the foundation of society. Given the limitations of the limited human resources of the police, we are researching efficient police activities and new investigation methods utilizing ICT, as well as crime prediction through crime occurrence analysis.
In addition, in order to protect the lives of citizens who are extremely difficult to rescue by self-help and mutual aid in the event of a disaster such as a torrential downpour or a massive earthquake caused by global climate change, we are conducting research on how local governments, self-defense forces, fire departments, and police can act to protect citizens by utilizing ICT technology to gather information on their daily living conditions. We are also conducting research on how local governments, the Self-Defense Forces, fire departments, and police can act to protect the public.
