Abstract

「砂場」は、子どもの成長と発達に影響を与える重要な遊具である。だが、現代日本ではその評価が低く、特に公園における砂場の設置率は5割を切っている。また保育・教育の分野においても必ずしも良好な環境とはいえないところが多い。本研究では、このような砂場問題の根本的な原因のひとつとして「砂」の不適切性を指摘し、「適切な砂」の基準仮説を示すとともに、その検証を試みて砂場環境改善の方向性と意義を論じた。, 研究ノート(博士資格論文)(Note(Doctoral qualification thesis))

Abstract

2014年に実践した「一粒のカカオから」と題した博学連携教員ワークショップをふりかえり，その内容を紹介するとともに，改善点や意義について考察した。2008年と2009年に行ったチョコレートを素材としたワークショップと異なる点は，焙煎したカカオ豆をすりつぶして香りや苦みを味わう体験から始めたこと，また，常設展示場に足を運び，サトウキビの圧搾機を前に，三角貿易の歴史から現在につながる南北問題の原因を考えようとしたことの2 点である。さらに鈴木紀をリソースパーソンに，フェアトレードについて理解を深めることとした。
