​The Marketing Push for Educational Technology: A Misguided Policy 


``然而,在2020年代,這種理論不再有效:技術在學生的日常生活中無處不在。 即使是低收入學生也有智能手機。


從1970年代開始,到1980年代,1990年代和2000年代初期,這種趨勢不斷發展,人們開始為學校配備“computer roooms”來輔助教學。 在此初期,其動機主要是讓貧困家庭的學生能夠使用電腦,因為他們中的許多人在家中沒有電腦或任何IT技術。  

Internet Addiction Disorder 網絡成癮症

​Research at top universities, such as M.I.T., The London School of Economics, U.C.L.A., and New York University has confirmed the negative effects of electronic screen time on people, especially kids.  These negative effects include eye strain, ADHD, depression, and poor concentration and social skills.  Electronic learning devices also do not improve academic performance.  Using paper books, flashcards, and board games is better than electronic learning devices.

Beginning in the 1970's and increasing in the 1980's, 1990's and early 2000's, there was a push to equip schools with "computer rooms" to aid in instruction.  In the early days of this, the motivation was primarily to give students from poorer families access to computers because many of them did not have a computer -- or any IT technology -- at home.  

A London School of Economics study of more than 100,000 primary school students found that smartphones reduce children's school marks by an average of -6.4%.  The negative result was even worse in students with poor concentration. 

美國兒科協會是美國兒童醫生的專業協會。 他們反复警告過智能手機,平板電腦和其他電子屏幕設備對孩子的影響。 他們已經發布了父母指南。

1. 沒有證據表明電子教育可帶來任何教育收益。
2. 2 歲以下的兒童不應接觸電子屏幕。
3. 父母應避免在年幼的孩子在場的情況下使用電子設備,例如智能手機。
4. 10歲以下的兒童每天應限制在1小時以內的高質量電子屏幕時間。
5. 兒童的電子屏幕播放時間會導致ADHD和SEN(學習障礙)。
6. 父母應與年幼的孩子一起閱讀。
7. 父母應與子女一起玩非電子教育遊戲。

Robert appeared on the RTHK radio show "Talkback" debating the benefits of Educational Technology vs. the proven harmfulness.

諸如M.I.T.,U.C.L.A。的倫敦經濟學院和紐約大學等頂尖大學的研究已經證實了電子屏幕播放時間對人,尤其是孩子的負面影響。 這些負面影響包括眼睛疲勞,注意力不足過動症,抑鬱症以及注意力不集中和社交能力差。 電子學習設備也不能提高學習成績。 使用紙質書,閱讀卡和棋盤遊戲要比使用電子學習設備更好。

​However, in the 2020's, this rationale is no longer valid:  Technology is omnipresent in student's everyday lives.  Even low-income students have smartphones.  

The American Academy of Pediatrics is the professional association of children’s doctors in the US.  They have repeatedly warned about the effects on children of smartphones, tablets, and other electronic screen devices.  They have published guidelines for parents.

1. There is no evidence of any educational benefit from electronic education.
2. Children under 2 years old should not be exposed to electronic screens.
3. Parents should avoid using electronic devices such as smartphones in the presence of their young children.
4. Children under 10 years old should be limited to 1 hour per day of quality electronic screen time.  
5. Children's electronic screen time can cause ADHD and SEN (learning disabilities).
6. Parents should read with their young children.  
7. Parents should play non-electronic educational games with their children .  

倫敦經濟學院對超過100,000名小學生進行的研究發現,智能手機將兒童的學校成績平均降低了-6.4%。 對於注意力不集中的學生,負面結果甚至更糟。
