Active Learning Models in Science Classes

研究の第１年次に当たる本年は，理科におけるアクティブラーニング型授業の構造化に向けて，内化と外化の往還を取り入れた授業デザインとその実践に取り組み，具体的実践の蓄積を行った。小学校，中学校，高等学校それぞれで実践を行ったところ，１）学習内容の定着が図られる，２）発展的な内容や未習内容を生徒が主体的に理解することが可能である，３）協働的な学びの場面を加えることで理解の深化が図られる，４）どのような課題に取り組ませるのかといった課題の設定がカギである，５）アクティブラーニングであるか否かを判断するための要素を明らかにする必要がある，などの一定の成果と課題が明らかになった。The purpose of this study is to create active learning models in science classes. As the first-year research, the authors designed the classes which would include a round trip between externalization and internalization, and put them into practice. The designed models were adopted in elementary, junior high and senior high school classes. What have become clear are as the following; 1) Students’ acquisition of the learning contents can be promoted, 2) Students can understand advanced contents proactively, 3) Students’ learning can be deepened by adding collaborative activities, 4) The success or failure to active learning may depend on the quality of the tasks which students work on, 5) It is necessary to clarify the factors to determine active learning

The Role of Science Education in the Construction of a Knowledge-Based Society

知識基盤社会における理科の役割は，科学的に探究する活動を通して得られた結果（情報）を活用し，それらの情報から導き出した自らの考えを表現する能力を高めることである。これまでに明らかになったことは，授業者が実験結果に対して関連付けることができる事項を明確にし，分析・解釈する視点を与えることが重要であるということである。今年度は，小学校，中学校，高等学校の理科で，パフォーマンス課題を取り入れた探究活動を行い，多くの授業者が共有できる方向性を考えた。実践の結果，以下のことが明らかになった。１）小集団での話し合いの質を高めるためには，話し合いの目的と方法を明示することが重要であること。２）そのために授業者の関わり方を引き続き検討する必要があること。３）パフォーマンス課題の設計には授業者がよりメタ認知を働かせることが必要であること。今後は，このような実践経験を広く共有すべきであると考えている。Science education should help students to utilize results and information through activities, to investigate scientifically, and to develop their abilities to express ideas they have derived from those results. We have learned that it is important for instructors to clarify which results from experiments relate to each other and to give students some clear perspectives for analyzing and interpreting them. This academic year, we investigated performance tasks at elementary, junior high, and senior high school levels. Through our research we have learned that to improve the quality of discussion in small groups, it is important to make the purpose and method clear. We also showed that instructors should monitor how they engage with students in the course of discussion and that they need to function meta-cognitive abilities more to design performance tasks

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
