The wide-scale global movement of school education to remote instruction due to Covid-19 is unprecedented. The use of educational technology (EdTech) offers an alternative to in-person learning and reinforces social distancing, but there is limited evidence on whether and how EdTech affects academic outcomes. Recently, we conducted two large-scale randomized experiments, involving ~10,000 primary school students in China and Russia, to evaluate the effectiveness of EdTech as a substitute for traditional schooling. In China, we examined whether EdTech improves academic outcomes relative to paper-and-pencil workbook exercises of identical content. We found that EdTech was a perfect substitute for traditional learning. In Russia, we further explored how much EdTech can substitute for traditional learning. We found that EdTech substitutes only to a limited extent. The findings from these large-scale trials indicate that we need to be careful about using EdTech as a full-scale substitute for the traditional instruction received by schoolchildren.

The wide-scale global movement of school education to remote instruction due to Covid-19 is unprecedented. The use of educational technology (EdTech) offers an alternative to in-person learning and reinforces social distancing, but there is limited evidence on whether and how EdTech affects academic outcomes, and that limited evidence is mixed.1,2 For example, previous studies examine performance of students in online courses and generally find that they do not perform as well as in traditional courses. On the other hand, recent large-scale evaluations of supplemental computer-assisted learning programs show large positive effects on test scores. One concern, however, is that EdTech is often evaluated as a supplemental after-school program instead of as a direct substitute for traditional learning. Supplemental programs inherently have an advantage in that provide more time learning material.

Recently, we conducted two large-scale randomized experiments, involving ~10,000 primary school students in China and Russia, to evaluate the effectiveness of EdTech as a substitute for traditional schooling.3,4 In both, we focused on whether and how EdTech can substitute for in-person instruction (being careful to control for time on task). In China, we examined whether EdTech improves academic outcomes relative to paper-and-pencil workbook exercises of identical content. We followed students ages 9–13 for several months over the academic year. When we examined the impacts of each supplemental program we found that EdTech and workbook exercise sessions of equal time and content outside of school hours had the same effect on standardized math test scores and grades in math classes. As such, EdTech appeared to be a perfect substitute for traditional learning.

In Russia, we built on these findings by further exploring how much EdTech can substitute for traditional learning. We examined whether providing students ages 9–11 with no EdTech, a base level of EdTech (~45 min per week), and a doubling of that level of EdTech can improve standardized test scores and grades. We found that EdTech can substitute for traditional learning only to a limited extent. There is a diminishing marginal rate of substitution for traditional learning from doubling the amount of EdTech use (that is, when we double the amount of EdTech used we do not find that test scores performance doubles). We find that additional time on EdTech even decreases schoolchildren’s motivation and engagement in subject material.

The findings from the large-scale trials indicate that we need to be careful about using EdTech as a full-scale substitute for the traditional instruction received by schoolchildren. There are two general takeaways: First, to a certain extent, EdTech can successfully substitute for traditional learning. Second, there are limits on how much EdTech may be beneficial. Admittedly, we need to be careful about extrapolating from the smaller amount of technology substitution in our experiments to the full-scale substitution in the face of the coronavirus pandemic. However, these studies may offer important lessons. For example, a balanced approach to learning in which schoolchildren intermingle work on electronic devices and work with traditional materials might be optimal. Schools could mail workbooks to students or recommend that students print out exercises to break up the amount of continuous time schoolchildren spend on devices. This might keep students engaged throughout the day and avoid problems associated with removing the structure of classroom schedules. Schools and families can devise creative remote learning solutions that include a combination of EdTech and more traditional forms of learning. Activities such as reading books, running at-home experiments, and art projects can also be used to break up extensive use of technology in remote instruction.

The clock for the New Strategic Arms Reduction Treaty runs out on February 5. The Trump administration has not taken up Russia’s offer to extend the treaty, believing it has leverage to get something more from the Kremlin, and it has even threatened an arms race.

This is delusion and bluff. If the administration does not change course, New START will lapse and, for the first time in decades, U.S. and Russian nuclear forces will be under no constraints.

Where is nuclear arms control—negotiated restraints on the deadliest weapons of mass destruction—headed? This 50-year tool of US national security policy is currently under attack. The New Strategic Arms Reduction Treaty (New START), the last remaining nuclear arms agreement with the Russian Federation, will go out of force in February 2021 unless it is extended for an additional five years as the treaty permits. At this moment, nothing is on the horizon to replace it.

Since regaining its independence in the aftermath of the Soviet Union’s collapse nearly 30 years ago, Ukraine has sought to build links with the West. This includes ties with institutions such as NATO, with which Ukraine has established a distinctive partnership. Kyiv has been keen on deepening those ties. Its interest in becoming a NATO member has continued to grow since 2014, as it views NATO as a means to protect Ukrainian sovereignty and territorial integrity from its aggressive neighbor, Russia.

Although NATO-Ukraine cooperation has intensified, and the Alliance maintains its “open door” policy, NATO members appear reluctant to put Ukraine on a membership track. Despite the fact that Russia continues a low-intensity conflict against Ukraine—and occupies Ukrainian territory—Kyiv can expand its practical cooperation with NATO. However, in the near term, Kyiv will have to keep its expectations about membership modest.

From 2001 to 2004, I was the senior American official to visit Belarus. The United States and European Union were thoroughly dissatisfied with President Alyaksandr Lukashenka’s authoritarianism, and US policy mandated that no official higher than a deputy assistant secretary travel to Minsk. EU officials and EU member states observed comparable restrictions.

Washington had no particular geopolitical interest in Belarus, and trade was minimal. During my first visit in February 2002, the primary objective was to persuade the Belarusian government to ease up on repression, respect human rights, and allow a bit more political space. We presented Belarusian officials two lists. List A enumerated actions the US government wanted Belarus to take; List B laid out steps that Washington could take to improve bilateral relations. We told our counterparts that if they indicated what things from List A they would do to improve human rights and the political atmosphere, we would tell them what actions from List B the United States would take in response.

The Belarusians gave us nothing.

My second visit to Minsk came in March 2004 on a joint US-EU mission to encourage the Belarusian government to improve its human rights record. My EU colleagues and I presented a coordinated position. We noted our readiness to improve relations, including taking steps sought by Belarusian officials, provided that the government ease domestic repression. Once again, the Belarusians gave us nothing to work with.

I then traveled on from Minsk to Moscow for consultations and raised Belarus with a Russian deputy foreign minister. I noted that the United States and Russia had competing geopolitical interests regarding Ukraine, but that this was not the case with regard to Belarus. There was no push in Minsk to join the European Union, and zero Belarusian interest in NATO. Neither Washington nor the European Union clamored to pull Belarus closer. The primary Western aim was to get Lukashenka to ease up on the repression. Was this an issue on which the United States, Europe, and Russia could work together?

My Russian interlocutor listened politely, but his body language answered all too clearly. The domestic political situation in Belarus did not trouble him. And, in any case, if something needed to be done there, Russia would handle it on its own.

That Moscow meeting has come to mind once again in recent weeks as Belarusians have protested against a sham election. They are protesting in a way they have not protested in the nearly three decades since Belarus became an independent state. While Lukashenka, who has held power for 26 years, rails against Western interference, Western criticism focuses on democratic norms and a stolen election. There is no burning desire to pull Belarus into the West. Both the European Union and NATO have more than enough on their plates.

Likewise, the protests in Belarus are about democracy, not about a Westward geopolitical course. Presidential candidate Sviatlana Tsikhanouskaya, who according to credible exit polls won the August 9 presidential ballot, has said: “[The protest movement] is neither a pro-Russian nor an anti-Russian revolution. It is neither an anti-European Union nor a pro-European Union revolution. It is a democratic revolution.”

The absence of a geopolitical component to the current protests is perhaps not surprising. Indeed, it is worth underlining that of all the states to emerge from the wreckage of the Soviet Union in 1991, Belarus seemed the least certain about what to do with independence and the most interested in maintaining close relations with Russia.

As in 2004, Moscow presumably has no desire to coordinate with the West on how to handle the crisis that Lukashenka’s inept leadership and stolen election have caused. In going it alone, the Kremlin faces a choice. Does it choose to back Lukashenka or an increasingly restive population?

The Russian government could choose to side with the Belarusian people. They could help ease the authoritarian president out of office and into a pleasant retirement in a dacha near Moscow, perhaps with former Ukrainian president Viktor Yanukovych living next door. In that case, Russia would likely gain a stable Belarus as a neighbor, with a population still – or perhaps even more – favorably disposed toward Russia and Russians.

There is an obvious drawback to this approach. The emergence of another pluralistic political system on Russia’s western border could give rise to greater questions from the Russian public as to why they cannot enjoy similar rights.

Backing Lukashenka would enable Russia to avoid such questions, but it could entail something significantly worse. A violent and prolonged crackdown supported by the Kremlin would lead to an increasingly radicalized Belarusian population that views Russia as thwarting its desire for a greater political voice. To Moscow’s disadvantage, this might bring geopolitical factors into play that are currently absent from the debate in Belarusian society. It could also fuel interest in “joining” the West.

On August 27, Vladimir Putin announced that Russia has already organized a reserve police force to assist Lukashenka if necessary. He should reconsider this. Over the past six years, Kremlin policies of intervention have been instrumental in pushing Ukraine away from Russia and toward the West. Does Moscow want to repeat this mistake with Belarus?

Much like Donald Trump’s approach to the coronavirus pandemic, Putin almost certainly hopes the protests in Belarus will just fade away. If they do not and the standoff deepens, Putin faces a hard choice. At present, he appears inclined to make the wrong decision, with potentially costly implications for Russia.

Failing to renew the New START arms control treaty with Russia “is not a wise direction of travel,” said Rose Gottemoeller, a former Deputy Secretary General of NATO who ranked as one of President Barack Obama’s top nuclear security experts. 

She knows better than most. Gottemoeller was the chief US negotiator at the Moscow and Geneva talks where details of the treaty were hammered out between 2009 and 2010. Officially ratified a year later, New START limited both the United States and Russia to seven hundred delivery vehicles and just over double that count in total warheads, and was reinforced with a stringent verification process to closely monitor each country’s compliance.

Paragraphs

President Donald Trump’s chief arms control envoy last week acknowledged the possibility that the 2010 New Strategic Arms Reduction Treaty (New START) could be extended, but he added, “only under select circumstances.”  He then put down conditions that, if adhered to, will ensure the Trump administration does not extend the treaty.

New START and Extension

New START limits the United States and Russia each to no more than 700 deployed strategic missiles and bombers and no more than 1,550 deployed strategic warheads.  It expires by its terms on February 5, 2021 but can be extended for up to five years.  The Trump administration has adamantly refused to do that.

From the perspective of U.S. national security interests, extending New START is a no-brainer.  As confirmed by the State Department’s annual report, Russia is complying with the treaty’s limits.  Extension would keep Russian strategic forces constrained until 2026.  It would also ensure the continued flow of information about those forces produced by the treaty’s data exchanges, notifications, on-site inspections and other verification measures.

And extension would not force a single change in U.S. plans to modernize its strategic forces, as those plans were designed to fit within New START’s limits.

Russian officials, including Vladimir Putin, have raised New START extension since the first days of the Trump administration.  In 2017, Trump administration officials deferred on the issue, saying they would consider extension after (1) completion of a nuclear posture review and (2) seeing whether Russia met the treaty’s limits, which took full effect in February 2018.

Russia fully met the limits in February 2018.  At about the same time, the administration issued its nuclear posture review.  Yet, more than two years later, New START extension remains an open question.

On June 24, Amb. Marshall Billingslea, the president arms control envoy, briefed the press on his meeting with his Russian counterpart two days before in Vienna.  Asked about extending New START, Amb. Billingslea—never a fan of the treaty or, it seems, any arms control treaty—left the option open.  However, he described three conditions that will block extension.

China

Amb. Billingslea’s first condition focused on China, which he claimed had “an obligation to negotiate with [the United States] and Russia.”  Beijing certainly does not see it that way—saying no, no and again no—citing the huge disparity between the size of the Chinese nuclear arsenal and those of the United States and Russia.  China has less than one-tenth the number of nuclear warheads of each of the two nuclear superpowers.

To be sure, including China in the nuclear arms control process is desirable.  But Beijing will not join a negotiation aimed at a trilateral agreement.  What would such an agreement look like?  Neither Washington nor Moscow would agree to reduce to China’s level (about 300 nuclear warheads).  Nothing suggests either would agree to legitimize a Chinese build-up to match their levels (about 4,000 each).  Beijing presumably would not be interested in unequal limits.

This perhaps explains why, well more than one year after it began calling for China’s inclusion, the Trump administration appears to have no proposal or outline or even principles for a trilateral agreement.

For its part, Moscow would welcome China limiting its nuclear arms.  The Russians, however, choose not press the question, raising instead Britain and France.  Amb. Billingslea pooh-poohed the notion, but France has as many nuclear weapons as China, and Britain has two-thirds the Chinese number.  The logic for bringing in one but not the other two is unclear.  The question raises yet another hinderance to including China.

A more nuanced approach might prove more successful.  It would entail a new U.S.-Russian agreement providing for reductions beyond those mandated by New START.  Washington and Moscow could then ask the Chinese (and British and French) to provide transparency on their nuclear weapons numbers and agree not to increase their total weapons or exceed a specified number.  Much like his president, however, the arms control envoy does not appear to be into nuance.

Non-Strategic Nuclear Weapons

Amb. Billingslea’s second condition dealt with including in a new negotiation nuclear arms not constrained by New START, especially Russia’s large number of non-strategic nuclear weapons.  Again, this is laudable goal, but getting there will require much time and unpalatable decisions that the Trump administration will not want to face.

Russian officials have regularly tied their readiness to discuss non-strategic nuclear arms to issues of concern to them, particularly missile defense.  The Trump administration,  however, has made clear that it has zero interest in negotiating missile defense.

Even if Moscow severed that linkage, negotiating limits on non-strategic nuclear weapons would take time.  New START limits deployed strategic warheads by virtue of their association with deployed strategic missiles and bombers.  The only warheads directly counted are those on deployed intercontinental ballistic missiles and submarine-launched ballistic missiles.

By contrast, most if not all non-strategic warheads are not mounted on their delivery systems.  Monitoring any agreed limits would require new procedures, including for conducting on-site inspections within storage facilities.  This does not pose an insoluble challenge, but it represents new territory for both Washington and Moscow.  Working out limits, counting rules and verification measures will prove neither quick nor easy.

Verification

Amb. Billingslea earlier suggested some dissatisfaction with New START’s verification measures, though he did not articulate any particular flaw, and, as noted, the State Department’s annual compliance report says Russia is meeting the treaty’s terms.  Last week, he made verification measures for his desired U.S.-Russia-China agreement the third condition for New START extension. 

Verification measures are critical.  Treaty parties have to have confidence that all sides are observing the agreement’s limits or, at a minimum, that any militarily significant violation would be detected in time to take countervailing measures.  Working out agreement on those measures will prove a long process, even in just a bilateral negotiation, especially if it addresses issues such as stored nuclear weapons.  That is not just because of Russian reluctance to accept intrusive verification measures such as on-site inspection; the U.S. military also wants verification measures that do not greatly impact its normal operations.

Russian officials have reiterated their readiness to extend New START now.  Amb. Billingslea’s conditions will thwart extension for the foreseeable future.  That’s unfortunate.  By not extending New START, the Trump administration forgoes a simple action that would strengthen U.S. national security and make Americans safer.
