Early childhood education and care is widely regarded as helping children’s academic, cognitive and social development. Our study, published in the journal Behavior Genetics, looked into whether attending preschool or childcare influences later academic achievement.

We found no statistically significant difference between the literacy and numeracy scores of school children who had attended preschool or childcare and children who didn’t. Nor did the duration of preschool or childcare attendance have an impact on later literacy and numeracy scores.

We did not look at the relations between social and emotional skills, and early childhood education and care.

Core rope memory was used for the Apollo Guidance Computer, the computer that ran all the navigation and controlled the spacecraft itself. For such a crucial function you needed as much reliability as possible. Because space (inside) was extremely limited, it needed to be extremely compact. And you really really did not want to accidentally wipe or overwrite it.

To meet all these criteria, the software for the guidance computer was literally hand-woven into it. The memory looked rope-like, hence the name, but really it consisted of clusters of wires (“ropes”) wrapped around magnetic cores. In contrast to normal computer memory, it wasn’t the cores but the configuration of the wires that carried all the information.

The bidders: Titus Flavius Claudius Sulpicianus, Pertinax’s father-in-law; Didius Julianus, the proconsul of North Africa. Sulpicianus was inside the Praetorian camp at the time and Julianus was not, so the advantage was his. He offered the enormous sum of 20,000 sesterces to each guard member. Guards at this time would have been paid about 2,500 sesterces a year, so you can imagine the size of this bid. But Julianus, immediately outside the encampment, shouted his bid: 25,000 sesterces each, ten years’ wages, if they would appoint him emperor instead. So they did.

Note that I keep saying viral RNA, not virus. We do not know if these kids were shedding live virus that was actively capable of infecting others. The authors did not do viral cultures or other infectivity assays. So the errors in the headline? The word contagious. Higher viral load does not necessarily mean more contagious.

With schools reopening after COVID-19 closures, concerns about the safety and certainty of public schooling have driven some parents to consider alternatives to sending kids back to brick-and-mortar classrooms.

One option making headlines is the formation of “learning pods” also known as “pandemic pods.” Pandemic pods are small groups of children from different families who learn together outside of traditional school buildings.

While pandemic pods may seem relatively harmless, they are part of a growing trend towards education privatization that undermines public education and democracy.

As Election Day approaches, he confronts not only an incumbent Republican president flush with campaign cash but also a nearly two-century-old hazard of history. Since the 1830s, the vice presidency has become a dead end for Democratic aspirants to the White House. 

Interestingly, the middle-class parents we spoke to used NAPLAN as a tool designed for them to check on their children’s progress and help them improve. But the working-class parents we spoke to saw NAPLAN as a tool for governments, and didn’t use the results to judge their child’s progress or seek additional help based on the results.

All the working-class parents we spoke with saw NAPLAN as a tool for government to assess schools and teachers. Parents did not see NAPLAN testing or reporting as something for them.

Every student is guilty until the algorithm proves her innocence.

However, what could not be fixed in the remote teaching and learning model were the persistent infrastructure and network holes, glaring social-cultural inequities and social-community environments that are not conducive to learning.

Yes, there are racial inequalities in testing that should concern us. But no one – no one – was helped more by a strong SAT score than a poor black kid.
