Whenever I share the method of splitting the textbooks to friends and relatives, I would be told that it is a good and original idea. But while drafting this article, I did a Google and found the phrase "split volume". It's the same concept, but the publisher of the textbook, not the parent, applies the procedure in the printing shop.
In response to the bill, SBE conducted research and consulted stakeholders in 2003 until 2007. Among the adopted recommendations was a weight standard for elementary and secondary textbooks.
SBE also required publishers to offer light versions of textbooks if they exceed a weight threshold. “These lighter weight alternatives may include, but are not limited to, split volumes, electronic editions, soft-cover editions or other alternate physical formats. “
Pediatricians and chiropractors consulted in the SBE research “recommend that students not carry more than fifteen percent of their body weight in a backpack, or risk negative health impacts.”
In 2016, I found an excellent printing press near our house. It's called Nafe Coop Printing Press and is in the basement of CLIMBS Building, Zone 5, Upper Bulua, Cagayan de Oro. It's just a few steps from Gaisano Bulua. Nafe has split my children's textbooks, and repaired my damaged books. Send email to email@example.com.
On May 19, 2017, ABS-CBN interviewed a medical doctor who gave advice on using backpacks for children. This footage is only a section of the entire show.
