Dimensions科學教材G2-G5家庭教學

最早知道小花生網就是通過Dimensions的團購。后來也購入了G2-G5的全套教材。關于G2的教學也有過一些實踐體會，收錄在專題“Dimensions”中。當初娃的閱讀水平是G2勉強能讀。但隨著娃閱讀水平的提高，一直以來困擾我們的“英文閱讀能力和認知能力不匹配”問題逐漸消失。在這段時間里，娃在科學方面的中文閱讀也早已進入“深水區(qū)”。由于美國科學教材采取了“螺旋式上升”的理念，在低年級有些概念講得并不透徹，擴展也不豐富。我認為更好的方式是，將G2-G5的所有內容拿來整合為2年左右的課程。與此同時，娃在公立小學也有每周兩節(jié)科學課，要做作業(yè)考試；在家里做各種小實驗也有豐富的“經驗”。所以有大量的教材內容無需過多重復。

Dimensions教材的編寫理念，之前已經撰文論述。我雖然理化生地都學到了至少大學入門課的水準。但在看這套書的時候，仍然覺得有新的收獲。關于科學和工程的事實性知識，現(xiàn)在的孩子們已經有太多渠道獲得。因此，科學教材必須超越事實性知識，也超越僅為趣味的實驗，為未來的理工科學習和研究打下基礎。

Dimensions教材內容梳理

(方括號內為課程數(shù))

G2 [15]

• Engineering and Tech: Engineering Design Process[2]
• Physical Science: Matter[4]
• Life Science: Environments for Living Things[4]
• Earth and Space Sciences: Earth's Surface[2], Changes to Earth's Surface[3]

G3 [21]

• Engineering and Tech: Engineering Design Process (more detailed)[3]
• Physical Science: Forces[3], Motion[2]
• Life Science: Life Cycles and Inherited Traits[3], Organisms and Their Environments[4]
• Earth and Space Science: Fossils[2], Weather and Patterns[4]

G4 [25]

• Engineering and Tech: Engineering Design Process (even more detailed)[3]
• Physical Science: Energy[3], Waves and Information Transfer[3]
• Life Science: Plant Structure and Function[2], Animal Structure and Function[3]
• Earth and Space Sciences: Changes to Earth's Surface (more detailed)[4], Rock and Fossils (more detailed)[3], Natural Resources and Hazards[4]

G5 [20]

• Engineering and Tech: Science and Math, Design Process, Technology and Society[3]
• Physical Science: Matter (more detailed)[3]
• Life Science: Energy and Matter in Organisms[3], Energy and Matter in Ecosystems[2]
• Earth and Space Science: Systems in Space[4], Earth's Systems[3], Earth and Human Activities[2]

可以看出，在低年級，各種概念相對獨立。年級越高，多學科的交叉整合越突出。

Dimensions家庭教學大綱

以下是我為孩子制作的課表，分為4個學期共64周。僅供參考。每周1-2小時即可。一些事實知識較多的，安排的周數(shù)較少；最后一學期有更多綜合的查資料做項目時間。其中部分內容他平時已經了解得很深入，就沒有安排太多時間。表中列出了前兩個專題的Project/Paper。由于平時在?？茖W課也會做一些實驗，所以將來在開展后續(xù)課程時，再根據(jù)自己的需求進行調整。

表格為MarkDown制作，可以到網易云筆記新建一則MarkDown筆記，然后將如下代碼黏貼：
