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。

The text describes "数の線繋ぎマッチング" (Number Line Matching), an educational app designed for children aged 2 to 6, including those in special education. This app facilitates learning basic number concepts interactively, suitable for early childhood numeracy education. The app's learning method involves connecting lines between two items representing the same number. It offers six types of elements to choose from: concrete objects like strawberries or cars, numerical digits, finger numbers, and numbers in Hiragana and Kanji. This approach helps in visual matching and numerical understanding, making it an effective tool for teaching numbers to young learners. The creator, with 15 years of experience in special education, developed this app to overcome the limitations of traditional print-based learning methods. It addresses issues like pencil control, line drawing, and the tendency of students to memorize set patterns in print materials, which are common challenges in traditional teaching methods. The app features include: 1. **Choice of Learning Elements**: Offers six different elements related to numbers for matching, providing a varied learning experience. 2. **Adjustable Difficulty**: Customizable to the child’s developmental level, it includes options for the range of numbers presented and the number of problems, facilitating progressive learning. 3. **Repeated Practice**: Generates problems randomly, preventing memorization of answers and enabling effective repeated practice. 4. **Simple Interface**: Designed to be user-friendly and easy to understand, making it accessible even for beginners. 5. **Free to Use**: The app is available for free, ensuring it is accessible to a wide audience, reflecting the developer's commitment to widespread education. The app aims to develop foundational numerical concepts, enhance cognitive skills, improve attention and memory, and foster logical thinking. It is particularly useful for early childhood education and is an invaluable resource for children in special education, offering a comprehensive and interactive learning experience.
