本子計畫四為數位自主學習計畫第一階段之前導研究，籌劃發展使用以「能量轉換與守恆」與「測量與尺度」之核心概念發展線上診斷評量工具與數位學習教材。並研究多元學習材料與管道（文本、教學、實驗、互動式介面）等學習活動設計科學素養數位學習模組。

　　The goal of subproject IV is to layout a plan to develop a Science self-directed e-learning module that use “energy conservation and transformation” and “measurement and scales” as major concepts to form diagnostic tools and e-learning materials. Adapting diverse learning activities (texts, teachings, experiments, and interactive activities), we intended to develop a comprehensive learning module for Science core competencies.
