ADHD(注意欠如多動性障害)・ASD(自閉症スペクトラム障害)・LD(学習障害)を中心とした学習に困難がある児童は、行動面の問題に比べ、学習面の問題は気づかれにくく、学びにくさへの支援が十分とは言えない状況です。その大きな要因の一つが、学習面でのアセスメントツールの不足でした。 LD-SKAIP(Screening Kit for Academic Intervention Program)は、学力のつまづきの状態と要因を3段階のステップの中で明確にし、その多様な検査結果から、個別の指導計画と教材選定、合理的配慮につながる的確な情報を得ることができます。 iPadを活用した検査であるため、子どもへの負担が少なく、また教示や分析作業の自動化、情報管理システム等により教師への負担も軽減しつつ、効率のよい、一貫した支援が可能となります。 ステップⅠでは、学校などでの支援に必要な発達の概要を把握するために、「話す・聞く」「読む・書く」「算数・その他」「行動」「社会性」の各分野別、合計93項目の「質問項目による査定」に回答し、結果を閲覧していただくことができます。
