高校生における異文化体験と国際的資質の関連 : 海外研修旅行の効果

本研究の目的は， 日本の高校生を対象に，国際的資質が海外研修旅行における異文化体験へ与える影響を検討することであった。3か国のうち1か国を選択して海外研修旅行を経験した高校生158人に対し，国際的資質および異文化体験を測定する賀問紙調査を実施した。その結呆，旅行後の国際的資質が有意に高まったが，その効果量は低かった。また異文化に対する認識の肯定的変化は，旅行の結果高まったほか，旅行前の国際的資質に強く影響受けることが明らかとなった。教育効果の検証における個人要因導入の必要性について考察された。The purpose of this study was lo examine the impact of international disposition on cross-cultural experiences in an oversea school trip among Japanese high school students. 158 high school students who participated in one in three foreign countries\u27 trip answered the questionnaire regarding international disposition and cross-cultural experiences. The results showed that scores of international disposition significantly increased but the effect sizes were moderate. Positively changes of the realization toward other countries also increased and were positively influenced by international disposition before the trip. Application of individual factors to the examination of the teaching effectiveness was discussed

The ASTRO-H X-ray Observatory

The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS). ASTRO-H will investigate the physics of the high-energy universe via a suite of four instruments, covering a very wide energy range, from 0.3 keV to 600 keV. These instruments include a high-resolution, high-throughput spectrometer sensitive over 0.3-2 keV with high spectral resolution of Delta E < 7 eV, enabled by a micro-calorimeter array located in the focal plane of thin-foil X-ray optics; hard X-ray imaging spectrometers covering 5-80 keV, located in the focal plane of multilayer-coated, focusing hard X-ray mirrors; a wide-field imaging spectrometer sensitive over 0.4-12 keV, with an X-ray CCD camera in the focal plane of a soft X-ray telescope; and a non-focusing Compton-camera type soft gamma-ray detector, sensitive in the 40-600 keV band. The simultaneous broad bandpass, coupled with high spectral resolution, will enable the pursuit of a wide variety of important science themes.Comment: 22 pages, 17 figures, Proceedings of the SPIE Astronomical Instrumentation "Space Telescopes and Instrumentation 2012: Ultraviolet to Gamma Ray

Hitomi (ASTRO-H) X-ray Astronomy Satellite

The Hitomi (ASTRO-H) mission is the sixth Japanese x-ray astronomy satellite developed by a large international collaboration, including Japan, USA, Canada, and Europe. The mission aimed to provide the highest energy resolution ever achieved at E  >  2  keV, using a microcalorimeter instrument, and to cover a wide energy range spanning four decades in energy from soft x-rays to gamma rays. After a successful launch on February 17, 2016, the spacecraft lost its function on March 26, 2016, but the commissioning phase for about a month provided valuable information on the onboard instruments and the spacecraft system, including astrophysical results obtained from first light observations. The paper describes the Hitomi (ASTRO-H) mission, its capabilities, the initial operation, and the instruments/spacecraft performances confirmed during the commissioning operations for about a month
