New York, December 6, 2016: Pre-school children’s skills in patterning, comparing quantities and counting objects were stronger predictors of their math achievement in fifth grade than other skills, researchers said.

The study showed that pre-school math skills supported first-grade math skills, which in turn supported fifth-grade math knowledge.

By first grade, patterning remained important and understanding written numbers and calculating emerged as important predictors of later achievement.

But, because not all types of math knowledge were equally important, certain early math topics should get more attention than they currently do, the researchers said.

“Counting, calculating, and understanding written numbers already get a lot of attention from teachers and parents, for good reasons,” said lead author Bethany Rittle-Johnson, Professor at Vanderbilt University in Tennessee, US.

“However, comparing quantities may merit more attention in pre-school and patterning knowledge may merit more attention in both pre-school and the early elementary grades,” Rittle-Johnson added.

The findings suggest that educators and school administrators may want to consider carefully which areas of math study should they shift attention to as they develop curricula for the early years.

For the study, the team followed 517 low-income children aged between 4-11.

Determining how to help children achieve in math is important, particularly for children from low-income families who often enter school with weaker math knowledge than their peers, the researchers suggested.

Google’s admission that it had in 2014 inadvertently coded the 112 distress number and the UIDAI helpline number into its setup wizard for Android devices triggered another controversy on Saturday as India’s telecom regulator had only recommended the use of 112 as an emergency number in April 2015.

After a large section of smartphone users in India saw a toll-free helpline number of UIDAI saved in their phone-books by default, Google issued a statement, saying its “internal review revealed that in 2014, the then UIDAI helpline number and the 112 distress helpline number were inadvertently coded into the SetUp wizard of the Android release given to OEMs for use in India and has remained there since”.

However, the Telecom Regulatory Authority of India (TRAI) recommended only in April 2015 that the number 112 be adopted as the single emergency number for the country.

According to Google, “since the numbers get listed on a user’s contact list, these get  transferred accordingly to the contacts on any new device”.

Google was yet to comment on the new development.

Meanwhile, French security expert that goes by the name of Elliot Alderson and has been at the core of the entire Aadhaar controversy, tweeted on Saturday: “I just found something interesting. I will probably do full disclosure tomorrow”.

“I’m digging into the code of the @Google SetupWizard app and I found that”.

“As far as I can see this object is not used in the current code, so there is no implications. This is just a poor coding practice in term of security,” he further tweeted.

On Friday, both the Unique Identification Authority of India (UIDAI) as well as the telecom operators washed their hand of the issue.

While the telecom industry denied any role in the strange incident, the UIDAI said that he strange incident, the UIDAI said that some vested interests were trying to create “unwarranted confusion” in the public and clarified that it had not asked any manufacturer or telecom service provider to provide any such facility.

Twitter was abuzz with the new development after a huge uproar due to Telecom Regulatory Authority of India (TRAI) Chairman R.S. Sharma’s open Aadhaar challenge to critics and hackers.

Ethical hackers exposed at least 14 personal details of the TRAI Chairman, including mobile numbers, home address, date of birth, PAN number and voter ID among others. (IANS)
