小学生の学校生活における身体活動量と体力に関する研究
JaLCDOI 10.18926/CTED/70359
Title Alternative Physical Activity and Physical Fitness in the School Life of Elementary School Children
FullText URL cted_016_045.pdf
Author YASUNOBE, Jin| SASAYAMA, Kensaku| ADACHI, Minoru|
Abstract 　本研究の目的は，小学校6年生の学校生活における活動場面別の身体活動量を加速度計を用いて客観的に測定し，その体力との関係を検討することである．対象は小学校児童85名(男子41名，女子44名)とし，休み時間，体育授業，学校生活全体における歩数と強度別活動時間を評価した．その結果，男女ともに体力上位群は休み時間において歩数とMVPAが多い傾向が示され，特に男子は中休み，女子は昼休みおよび体育授業で有意差が認められた．各活動場面のMVPA が占める割合は休み時間11.3％，体育授業15.7％であり，諸外国と比較して少なく，国際的推奨値にも届かなかった．本研究は，小学校における身体活動量の基礎データを提示するとともに，学校生活，特に休み時間や体育授業における身体活動機会の充実が必要であることを示唆した．

Title Alternative Analysis of Factors Contributing to Confusion Regarding Left-Right Understanding of Convex Lens Images —Proposals for Inquiry-Based Learning Based on Textbook Analysis and Teacher Questionnaire—
FullText URL cted_016_031.pdf
Author TANIMOTO, Kunihiko| INADA, Yoshihiko|
Abstract 　本研究は、中学校理科の凸レンズ学習で生徒が像の向きに抱く混乱に着目した。その要因を、光源・スクリーン・観察場所といった実験条件が十分に意識されてこなかった点にあると考察し、学習指導要領と教科書の変遷分析、および現職教員へのアンケート調査を実施した。その結果、教科書の記述は観察場所を指定する方向へ変化しているものの、現場教員の指導法にはばらつきがあり、生徒の混乱を招く一因となっていることを明らかにした。これらの課題解決のため、観察視点を自然に固定できる3D プリンタ製教材を開発し、教員研修でその有効性を検討した。本教材は生徒の直感的理解を促し、探究的な学びを引き出す上で有効であることが示唆された。

説明的文章の指導における「内省」を促す批判的読み ―高等学校１年生を対象として―
JaLCDOI 10.18926/CTED/70357
Title Alternative Critical Reading Instruction of Expository Text that Promotes Reflecting: Practice for First-year Student at High School
FullText URL cted_016_015.pdf
Author SAISHO, Yumi| IKEDA, Masafumi|
Abstract 　批判的読みは，現代では欠かせない能力であり，学習指導要領にも明記されている。近年，批判的読みの指導に関する研究がなされているものの，内容的な価値の検討や社会的な文脈のなかで捉えることが希薄だとする指摘や，「反省性」という観点に着目した批判的読みを求める声もある。そこで，本稿では，文章そのものを批判的に読むだけでなく，自身の持っている考えをも批判的に捉える（内省する）ことを促す授業を開発した。その手立てとして，複数の社会認識が存在する二つの教材の読み比べたうえで，対立する立場からの意見交換を行うことや，教材に対する評価の記述，その記述（自己の読み）を学習者自身が評価するといった活動を取り入れた。学習者の記述の分析からは，意識的な内省に至らなかった学習者も見受けられたものの，約６割の学習者の記述には変容が見られ，用いた手立ては効果があったと推測できることを指摘した。

外国人幼児の就学支援における保育士の工夫と実践的課題

Title Alternative Preschool Teachers’ Strategies and Practical Challenges in Supporting the School Enrollment of Foreign Children
FullText URL cted_016_001.pdf
Author CHEN, Yiwen| YANAGISAWA, Kazuki| REN, Xinyu| YOSHITOSHI, Munehisa|
Abstract 　本研究は，外国人幼児が就学期に直面する困難に対応するため，保育士が行っている具体的な保育実践における支援の工夫と課題を明らかにすることを目的とした。外国人幼児の支援経験を有する保育士2 名に半構造化インタビューを行い，SCAT を用いた質的分析により，幼児および保護者への支援内容を整理した。その結果，言語面では視覚的支援ややさしい日本語を活用し，文化面では家庭文化と日本の園文化の調整が行われていた。発達支援においては，非認知的スキルの育成や医療機関との連携の必要性が指摘された。保護者支援では，参加型の関わりや丁寧な説明が実践されていたが，制度情報の提供や行政との連携には課題が残された。これらの結果を踏まえ，今後は保育士の個別的努力に依存しないためにも，多文化背景をもつ家庭への支援を制度的に支える地域連携体制の整備や，情報提供の標準化，日本語教育資源との接続を図る実践的仕組みの構築が求められる。

Title Alternative Large-scale rainfall characteristics at the heavy rainfall event around the western Japan during 5–7 July 2018
FullText URL esr_032_033_044.pdf
Author KATO, Kuranoshin| MATSUMOTO, Kengo| OTANI, Kazuo|
Abstract 　Large-scale rainfall characteristics at the heavy rainfall event around the western Japan for 5–7 July 2018 were analyzed with use of the 10-mimute precipitation data at the surface meteorological observation stations of the Japan Meteorological Agency, and so on. In this case, the area with 3 days total precipitation of near or more than 300 mm was distributed widely from northern Kyushu to Shiga and Fukui Prefectures. As in the many heavy rainfall events around Kyushu District in the mature stage of the Baiu season, contribution of the intense rainfall with more than 4 mm/10-minute (24 mm/h) attained about one third of the areal mean total precipitation. However, it is noted that the "not so intense rain" with less than 2 mm/10-minute (12 mm/h) also contributed to about one third of the huge total precipitation in the wide area. In short, this case could be characterized by the mixture of the western Japan type heavy rainfall event and the eastern Japan type one.

Title Alternative A trial of lesson practice at the university on the variety of heavy rainfall characteristics based on the 10-minute precipitation data toward promoting the meteorological disaster prevention literacy
FullText URL esr_032_021_031.pdf
Author KATO, Kuranoshin|
Abstract 　In the disaster prevention education on the heavy rainfall around Japan, it is also important to promote the meteorological literacy on the seasonal and regional differences of their rainfall characteristics such as the convective rain or stratiform rain, together with their total amount of precipitation and their occurrence frequency. As the first step toward the above purpose, the present study made a lesson practice for the university students by utilizing the 10-minute precipitation data for the four heavy rainfall events, in which the types of the heavy rainfall (although all the cases examined in the lesson are relating to the deep convective clouds) are rather different from each other, such as the differences of the rainfall intensity at the peak time, short-period variation of the rainfall intensity and the persistency of the rainfall including the "not so intense rainfall". The reports by the students seem to perceive the different features among these events briefly, but the students' attention to how long the intense rainfall with short-period variation or "not so intense rainfall" lasted was not so sufficient.
