| Outline of Final Research Achievements |
As STEM educational materials for fostering manufacturing competency, we focused on the "balance" since it has a simple mechanism, which can be modified to various structures, and it can be evaluated quantitatively the quality of the product. We have developed several educational materials applicable from elementary school students to lifelong education.
The main achievements include: i) "Active Learning Balance" for elementary and junior high school students, which allows them to freely design by using long screws; ii) "Original Spring Scale" for junior high school technology classes, which allows students to freely design by combining pre-fabricated parts; iii) "Electronic Reading Device for Spring Scale" using visible light photo-interrupters applying a step-by-step conceptual design, and iv) a "paper balance project" for teacher's license renewal courses.

| Academic Significance and Societal Importance of the Research Achievements |
個々の事象や理論を個別に学ぶ「コンテンツ教育」から，それらを縦横に組み合わせ社会の課題を解決する「コンピテンシー教育」への飛躍が求められている．その一つとして，本研究ではものづくりを「要」としたSTEM教育教材を開発した．
研究のポイントは，製品の評価に秤量精度を一貫して用いたことである．ものづくりのゴールに定量的かつ客観的な評価基準があることは非常に重要であった．評価の要が強固となることで，教材の難易度や構成の自由度が広がった．それぞれの授業／セミナーの要請に合わせて，てんびん／ばねばかりの要素を部分的にスピンアウトし，さまざまな形態のSTEM教育が可能なことが示された．
