In general PBL education, a role of excellent tutor is very important, but it is difficult to introduce excellent tutors into our PBL education. From this background, I have adopted mutual peer assessment of cooperative learning in order to activate our PBL. The cooperative learning will lead students to discover various subjects through cooperative self-instructions. The peer assessment will able to make the cooperative self-instructions more active without the tutors. This paper shows the performance of our cooperative PBL utilizing the peer assessments, and then the instructive effects of the adopted assessments are discussed.

Vocabulary is considered to be an important factor for English as a foreign language (EFL) learners to acquire the four key English abilities of reading, listening, writing and speaking. To develop EFL learners' vocabulary effectively, it is necessary to first measure freshmen's vocabulary size on entry. In Japan, the new course of study for Junior High Schools which defines the number of words learned at Junior High was introduced in 2012 and this changed the learning criterion of English vocabulary. The purpose of this study is to figure out how much receptive vocabulary the freshmen at National Institute of Technology, Kisarazu College have and to verify whether the change of the course of study affects their receptive vocabulary size. The results show that the college freshmen have a vocabulary size of 1162-1496 words out of 2000 words, and that the receptive vocabulary size of the college freshmen was unaffected by the revision of the course of study.

This paper is a report based on an attitude survey about "reading". A target of an investigation is the 2nd grade in National Institute of Technology, Kisarazu College. Recently, a decline of the language ability of the students is remarkable. Indeed, the quantity of their reading seems to decrease. Study in the college is too busy, and they can't read many books. So, it's necessary that the time and the comfortable place to enjoy "reading" are produced. Such as introducing a book each other between the friends, it's also effective to share the pleasure of the "reading".

This paper is about the bookshelf called "The Book Plaza". "The Book Plaza" at National language department in Kisarazu National College of Technology, is projected to attract students to prefer various books. It's exchanged between the books, so the line-up of the shelf is always replaced. So whenever someone comes, a new book is put back. Therefore there are no cases that the user gets tired of this shelf. Next to we compare this try with a town library in Obuse in Nagano. Obuse is the land where town promotion using a book is popular. And it's considered what kind of bookshelf charms a student. If you liked this paper, I wish you to try this project.

The number of developmentally disabled students has been increasing, so a lot of institutions of higher education are confronted with problems the students have. The purpose of this study is to show how Kosen should deal with the problems. In the beginning, we will consider what a developmental disability is and who is a developmentally disabled student. And I will show what kinds of efforts to solve the problems have been implemented. Finally, I will present a unique set of challenges for Kosen to improve the situation of the students.

It is pointed out that group learning can foster learners' sociability and enhance their learning motivation. In physical education classes, these effects can be expected by setting an appropriate tasks to carry out in a group. In the case of judo lessons, Maemawariukemi is more technically difficult than Usiroukemi and Yokoukemi. Therefore, the speed to acquire the skill, Maemawariukemi, varies from individual to individual. The purpose of this study is to examine the effects of group learning as an active learning method to learn Maemawariukemi.

The third grade students at the National Institute of Technology, Kisarazu College (Kisarazu Kosen) take the General Education Seminar called Ippan Tokubetsu Kenkyuu (Tokkenn). About 15 teachers of general subject instruct an average of 15 students in their courses. The General Education Seminar is considered to be a pre-stage of the graduation research of the fifth grade student. Students can learn how to research through the General Education Seminar. This paper reports on the practical contents of the author's courses in 2014 and 2015.

There are some characteristics of students who are poor at mathematics in class of lower grades. This article is devoted to class improvement in consideration the characteristics. In the class improvement I attend to take enough time that students solve problems independently. I report that writing learning is extremely effective for students.

Effects of nitrate concentration in hydroponic cultured Komatuna on the Spectral variations of the Laser-Induced Fluorescence (LIF), and on the Green Meter value (GM) were experimentally examined. NO₃^- in Komatsuna and GM was not likely related. LIF spectra intensity ratio at 740nm to 685nm (F740/F685), at 740nm to 530nm (F740/F530) and at 685nm to 530nm (F680/F530) increased with NO₃^- contained in Komatsuna. Especially F740/F650 was related to NO₃^- strongly (R²=0.806).

A simple method of comparative assessment of anthocyanin content was investigated by ultraviolet-visible (UV-Vis) spectroscopy using blueberry fruit. The extraction solution of anthocyanin from frozen crushed fruit was measured without centrifugation or filtration. The results showed a high correlation between the amount of sample and the absorbance. It was also showed that the anthocyanin content was vary considerably with variety of blueberry. Consequently, the method was expected to effectively use in functional food development and the other fields.

A non-destructive evaluation method for anthocyanin content in blueberry fruit was investigated by laser-induced fluorescence (LIF) spectra measurements. The LIF spectra had emission from flavonoid groups (F595), chlorophyll groups (F685) and others. The ratio of the fluorescence intensity F685/F595 under excitation at 532 nm was considered to be a good index for estimating the anthocyanin content of the blueberry fruits. The differences of anthocyanin content were suggested in different blueberries of ripeness degree or of variety by using this index.

In this paper, I introduce the method and the procedure of classes on the philosophy of "manabiai", which was advocated by Professor Nishikawa in Joetsu University of Education. In recent years the Ministry of Education insisted on introducing active learning to high school, junior high school, and elementary school in the next "gakushu sidou youryou". So our school is not necessarily followed by "gakushu sidou youryou", but I comment on classes in the first grader at our school from the view of "gakushu sidou youryou".

The color of skin on blueberry changes in dark bluish violet from yellowish green as it matures. The pigment ingredient causing the bluish violet is anthocyanin. It is useful for choice of the suitable kind or cultivation optimization, if we can evaluate the anthocyanin content of the blueberry in a condition bearing fruit. In this study, we irradiated the different blueberry fruit of the maturity degree with the broadband halogen bulb and measured the reflection spectrum from the blueberry surface, as fundamental researches to estimate anthocyanin content non-destructively. As a result of this measurement, it was found that the blueberry absorbs the light of wavelength 675nm. In addition, it was also found that mature blueberry absorbs the light of shorter wavelength than around 600nm.

From August, 2015 to August, 2016, an Overseas study was carried out at Massachusetts Institute of Technology(MIT), Cambridge, MA, USA. This program is sponsored by National Institute of Technology, Japan (Kousen-Kikou). The main purpose of the overseas study was to conduct research on the seawater pumped hydro plants. Here, The city of Cambridge, Boston, MIT, and my research will be discussed.

It is difficult that to accurately run periodic process in cycle of less than a few tens of millisecond, using normal Linux distributions with normal scheduling policy in round-robin fashion. This article shows an easy way to resolve the problem by replacing the kernel with a low latency kernel. Its performance of latency without intentional load was evaluated using a frequently-used command at various interval and priority. It is possible that to design original software which runs on the soft-realtime OS. To evaluate its usability, we demonstrated positional control of a manipulator every 5 milliseconds. By running the control software on CUI environment, standard deviation of the time interval was suppressed compared to running the same software on GUI environment.

The authors, in the last year, incorporated the design exercise of reinforced concrete bridge as the content of the course of reinforced concrete engineering. One of the aim was to make the students more effectively understand the design rules of the concrete structures. However, it didn't give the sufficient effects for students to understand the design rules. This paper describes some modifications are carried out in current year in order to solve the above problem.

The recent trend in education has promoted an increase in the use of active learning techniques which aims at ensuring the genuine quality of students. However, it is difficult for the old faculty development(FD) in our college to improve the active learning educations because of the variety of active learning applications. For the sustainable improvements in education, new college's ability to self-improve by the operation of the PDCA cycle is required. From this background, this paper suggests self-improving educations by active use of bulletin of own college as a teaching portfolio.
