| SSS●Word count | |
最新のYL一覧はこちら(The Latest YL & Wordcount Table)
１ ＳＳＳでは、タドキストの有志の協力、日本多読学会との協力、いろいろな図書のYL(読みやすさレベル)を定めています。
２ 実際に読書する個人の読みやすさは、人それぞれのバックグラウンドによってそれぞれ異なります。
特に、GR中心に読んでいる人の場合、同じYLの児童書を読みにくいと感じるのは普通のことです。
３ 一方、児童書中心に読んでいる人の場合、高いレベルの児童書も比較的苦労なく読めてしまうこともよくあります。
４ 標準的には、GRは理解度７０−８０％で読む場合、児童書は、理解度６０−７０％で読む場合を想定してYLを設定しています。
５ YLの大半は、これらの基本図書を基準に、「よりやさしいか？」、「大体同じか？」、「より難しいか？」を皆さんに書評システムで
投票してもらうことにより順次変更されていきます。
