Large-Scale Tutoring as a Solution for School Closure Losses: Is the Idea Taking Hold?

What will America’s schools be like when they reopen in fall, 2020?  There are many things we don’t know, and conditions will vary considerably from state to state and school to school.  To begin with, we need to strengthen our schools, to be sure they have the teachers and administrators and supplies they need to do their essential work.  However, schools will need more than just a return to the status quo.  One thing we can absolutely predict is that millions of children will have fallen far behind in their educational progression. In particular, many elementary students in the early stages of learning reading and mathematics will need effective and rapid assistance tailored to their needs to get back on track.  Dedicated teachers and other educators will do everything in their power to bring students back up to speed, but without additional assistance, it will be very difficult to overcome the losses so many children have experienced.  States and school districts will be struggling economically, so no matter how clearly they understand what needs to be done, they will need help.  Yet at the same time, there will be large numbers of capable people eager to help struggling children who will be on the sidelines, without jobs that enable them to make the difference they want to make.

If you have been following my blogs for the past month or so (here, here, here, and here), you will be aware that I have been writing quite a bit about the idea of recruiting, training, and deploying large numbers of tutors to work in schools that have been closed for many months due to the Covid-19 pandemic.  Our research and reviews of research have found that several one-to-one and one-to-small group tutoring approaches that use teaching assistants (usually people with college degrees but not teaching certificates) have demonstrated effect sizes of +0.40 or more, roughly equivalent to five additional months of learning over a school year.  No other type of educational service comes close to these impacts.  My argument has been that in the recession we will be facing when school opens in the fall, it would be good for the economy as well as essential for students to have government fund thousands of tutors to work with students who have fallen far behind grade level in reading or mathematics.

This idea may be taking hold.  For example, the State of Tennessee recently announced a plan to work with Big Brothers, Big Sisters to recruit and train people to serve as tutors, as a response to the school closures (here and here). On May 15, the House of Representatives passed the Heroes Act, which includes substantial additional funding for K-12 education.  This includes “initiatives to reduce education gaps.”  This could certainly include tutoring.  I heard that there was talk in the Senate about funding that could also support tutoring.  None of these federal initiatives are certain, but at this point, what is important is that solutions of this kind are in discussion.

blog_5-28-20_tutor_500x333          In addition, other observers are also proposing large-scale tutoring as a solution for the educational damage done by school closures (and as a means of providing essential employment to thousands of recent college graduates otherwise unable to enter the job market).  Jill Barshay wrote about this in a recent article in the Hechinger Report.  Matthew Kraft and Michael Goldstein wrote on the topic in a recent Brookings blog.  Susan Dynarski wrote an op-ed on the proposal in the New York Times.

One concern I have heard expressed about the tutoring plan is that with all the uncertainties about the progression of Covid-19 and plans to re-open schools, it is not clear whether schools will re-open on time or not, and whenever they do open, they may use double sessions or other means to reduce the number of children being taught at a given time, to allow for social distancing within schools.  If neither cures nor vaccines are available by the fall, late or partial school openings are indeed possible.  We and other tutoring providers are developing and piloting distance tutoring models, and are willing to share them with other tutoring providers, should this be necessary.  And if schools do not open in September at all, then the need for intensive solutions such as tutoring are that much greater, whenever schools open.

If large-scale tutoring is to be used as part of recovery plans for schools, then preparations need to be begun as soon as possible, to coordinate the efforts of various providers, and then begin to recruit and train tutors, trainers, and others whose efforts will be needed to make this all work.  It would be wonderful if some number of tutors could be ready to go, starting with the elementary grades, soon after students arrive in school, and then expand services to add capacity to serve additional children in need over the 2020-2021 school year.

In the late 1930s, the extraordinary potential of penicillin to treat wounds and diseases was known by scientists and government officials in Britain, and they knew that war was coming and that penicillin could save millions of lives.  However, no one knew how to mass produce enough penicillin to matter.  The British contracted with an American company to work rapidly on the problem, and by the start of World War II, there was enough penicillin for a start, and massive manufacturing capacity to make more.  In a way, we are in a similar situation with tutoring.  We know what has to be done to provide millions of American children with the most effective service known to put them back on track, and it is clearly going to be necessary to do so.  Yet we have a lot of work to do to make this happen in time.

The Covid-19 pandemic has caused great devastation in our economy, our society, and our schools.  There are many things we must do to repair these losses.  In each arena, we have to use the best methods we have to cost-effectively solve problems caused by the crisis.  In our field of education, there are many things that must be done, but tutoring, to ensure that students can catch up to grade level, should be part of this great effort.

Recovery 2020

After a harsh winter, spring has come.

It’s May.  The weather is gorgeous on the Chesapeake, the weather is getting warm, the air is delicious, the flowers are blooming.  From a slight distance, everything seems so normal.   But up close, nothing is normal.  People have settled into patterns of behavior that would be completely bizarre in normal times.  They are wearing masks everywhere as though they have always done so.  Neighbors  are  being as friendly as they can be without getting too close.   Not far away, we know there is chaos and catastrophe, and we all do what we can.  But every day, there is life to be lived, jobs to be done, children to cherish and nurture.

The school year is coming to an end.  In some places, schools have already closed weeks early.   Educators have gotten through the challenges of trying to operate schools when there are no schools to operate.  They have had to use stopgaps, such as distance learning, because there were gaps to stop.  But now we are entering a new phase: Recovery 2020.

Part of Recovery 2020 will be a struggle to open schools while minimizing health risks.  Schools may not even open in September, or may only partially open.  But whenever they fully open, the challenge we face as educators will be to create schools ready to provide extraordinary education to every student, however long they have been out of school and whatever they have experienced in the interim.

In a series of blogs over recent weeks (here, here, and here), I’ve proposed a number of actions schools should take to put students on a new trajectory toward success, engagement, self-esteem, health, and safety.  In this blog, I want to get more specific about some ideas I’d propose to make Recovery 2020 more than a return to the status quo.  More like Status: Go!

  1. Strengthen the Core

First, we have to make sure that the  core of the schooling enterprise, teachers, principals, and administrators, are supported, and their jobs are safe.  There will be a recession, but it cannot be allowed to do the damage the last recession did, when schools could not focus and innovate because they were scrambling to hold on to their staff, just to cover classes.  Federal and state funding must be used to ensure that school staffs can focus on their work, not on managing shortage-induced chaos.  Current school staff should also be able to receive top-quality professional development to enable them to use proven, effective teaching methods in the subjects and grade levels they teach, so they can enhance and accelerate their students’ progress.  School nurses, counselors, and other specialists in whole-child development need to be in every school.

  1. Train and Deploy Thousands of Tutors in Every State and District

blog_5-12-20_tutorcollage_333x500In fall, 2020, schools will open into a recession, yet they will have to make more of a difference in their students’ development than ever before.  Securing the jobs and professional support of school staffs is essential, but not enough.  Students will need personalized, effective support, so they can achieve greater success in school than they have ever had.

If there is a recession, many people will struggle to keep their jobs or to find new ones.  But as always, those who suffer most in a recession are people who are entering the labor market.  There will be millions of college graduates and others ready to work who will find enormous barriers to entering the labor market, which will be overwhelmed keeping experienced workers employed.  This is a huge problem, but also potentially a huge opportunity.  Schools will need help in accelerating student achievement to make up for losses due to school closures and then to continue beyond making up losses to growing gains.  An army of bright-eyed, bushy-tailed young people will be eager to get involved serving children.  Government will have to provide relief to these and other unemployed people, so why not have them make a difference in children’s education, rather than just receiving  emergency support?

The solution I am proposing is for government to create a fund, a Marshall Plan for education, to recruit, train, and deploy thousands of tutors in schools across America.  The tutors would be trained, coached, and supervised by experts to deliver proven small-group tutoring models, focused in particular on reading and math, in elementary and middle schools.  They would be paid as teacher assistants, but equipped with specific skills and supports to work with students who are behind in reading or mathematics in elementary or middle schools.  Schools would receive a number of tutors depending on their size and levels of disadvantage and achievement deficits, up to five or more tutors per school.  The tutors would work with struggling students in small groups, using tutoring models proven in rigorous research to be particularly effective.  These models are known to be able to add five or more months of gain to students’ usual yearly progress each year, more than making up the losses most students have experienced.  As time goes on, students who need more tutoring can receive it, so that they can continue to make more than one year’s gain each year, until they reach grade level.

While tutoring is worthwhile in itself, it will also serve a purpose in introducing promising young people to teaching.  School leaders should be enabled to identify especially capable young people who show promise as teachers.  Someone who has been a great tutor will probably become a great teacher.  These people should then be given opportunities to participate in accelerated teacher training leading to certification.  The quality and commitment the tutors show in their daily work will help school leaders identify an extraordinary group of potential teachers to enter classrooms eager and prepared to make a difference.

  1. Train and Deploy School Health Aides

Especially in schools serving many disadvantaged children, there are many children who are achieving below their potential just because they need eyeglasses, or suffer from chronic diseases such as asthma.  Trained health aides can be deployed to make sure that students receive needed eyeglasses, regularly take medication for asthma, and otherwise solve health problems that interfere with success in school.  Working with school nurses, health aides will also be needed to manage ongoing protections against Covid-19 and other threats to health.

After a harsh winter, spring has come.  The wise farmer celebrates, but then he plants.  In the same way, America’s education leaders should celebrate that we have somehow made it this far.  But celebration is not enough.  We have to plan, and to plant, anticipating the opportunity this fall not just to get back to normal, but to create a new normal, better than the one we had, in which we use our nation’s strengths to heal and to build.

Recovery 2020 will take efforts and expenditures beyond just returning schools and students to normal.  But this is essential, and the short- and long-term benefits to our children and our society are clear.  If we are are wise, we will start this process now, to prepare to mobilize resources and energies to open in the fall the best schools we ever had.

September, 2020: Opening School Doors to New Opportunities for Universal Success

“Now is the time for all good schools to come to the aid of their country.”

In times of great danger, nations have always called upon their citizens to volunteer to do what is necessary to solve their most pressing problems. Today, our most immediate crisis is, of course, the COVID-19 pandemic. This time, the heroes who have come forward are health care providers, who risk their lives to save the lives of others. The many people who work in essential services, such as grocery stores and pharmacies, also subject themselves to risks so that others can survive. Teachers across the country are working day and night to prepare online lessons, as well as helping get food to hungry students.  Behind the scenes, scientists are working to find cures, expand testing, and determine when it will be safe for our society to return to normal.

In a few months, we will face a new emergency. Schools will open. Hopefully, school opening will not pose major health threats to students and staff, assuming that the danger of infection has passed. But we will without any doubt face a new set of challenges in the education of the more than 50 million children in elementary and secondary schools in the U.S., as well as the billion students in the world as a whole.

blog_5-7-20_backtoschool500x333 2In the U.S., children re-entering our schools will have been out of school since March. Some may have kept up with their school work online, but most will have had little formal schooling for six months. This will be most serious, of course, among the students most at risk. By next September, 2020, millions of children will not only have missed out on schooling, but many will also be traumatized by what they have experienced since they were last in school. Many will have experienced the disease or death of a close relative. Many will have parents who have lost their jobs, and may have lived in fear of lacking food or safety.

This is a predictable crisis. No one can expect that schools and students will just pick up and carry on when schools re-open, as though they’ve just had a few snow days.  No teacher is going to say on Day 1, “Please open your textbook to the page where we left off last March.”

As educators and policy makers, it would be irresponsible to wait until schools re-open and only then take action to solve the entirely predictable problems. Instead, we need to prepare, starting today, to create the schools students will need in September, 2020, or whenever it is deemed safe for schools to open.

Here are a few ideas I would propose to address the problems students are likely to have.

  1. Bring all students up to grade level in reading and mathematics.

In two recent blogs (here and here) I discussed one aspect of this problem, the fact that many students will have fallen behind in basic skills because of their long absence from face-to-face school. I proposed a Marshall Plan for education, including mobilization of tens of thousands of recent college graduates, and others eager to help, to serve as paid tutors to students who are struggling in reading and/or mathematics.  As I noted, research overwhelmingly points to tutoring as the most effective strategy to accelerate the achievement of students who are performing below their capabilities.  According to the evidence, several one-to-one or one-to-small group tutoring models can routinely increase student achievement by an effect size of +0.40 in a year (almost equivalent to the difference between middle class and disadvantaged students). But what if students received effective tutoring for two years, or longer? What if their classroom teachers used teaching methods proven to be effective, contributing further to student success? What if schools could provide services to students with problems with their vision or hearing, or chronic health problems such as asthma? Based on what we already know how to do, a goal of steadily increasing the percentage of students performing at today’s definition of “at grade level” could increase each year, until virtually all students could expect that level of performance.

  1. Schools need to welcome back every child.

When students return to school after the long delay and trauma they may have endured, they need to be welcomed back with enthusiasm by all school staff. The return will create a psychological opportunity.  Students will always remember what happened on the first day, the first weeks, the first months. A big party to welcome students back is a good start, but students will need constant and sincere affirmations of their value and importance to the adults in the school. They need to be told, one at a time and by name, how much they were missed, and how glad everyone is that they are back, safe and healthy. I think the theme of each school should be “a once-in-a-lifetime chance to connect with the school,” not “at last, everything is back to normal.”

  1.  Schools need social emotional and health solutions

In addition to using proven academic approaches, schools need to implement proven social-emotional and health promotion strategies to help all students reconnect and thrive.  Strategies to build self-concept, positive relations with peers, concern for the well-being of others, and a commitment to banish violence and bullying will be especially important.  Cooperative learning can help to build friendships, acceptance, and engagement, in addition to improving achievement.

In light of all that has happened, schools need to enthusiastically welcome their students back, and then provide them the success, respect, and love that they deserve.  They need to give them every reason to believe that they have a new opportunity to achieve success.  Students, parents, and educators alike need to have well-founded confidence that out of the destruction caused by the pandemic, there will come triumph.

Marshall Plan II: Heal the Damage, But Build for the Future

At the end of World War II, Western Europe was devastated. Factories, housing, transportation, everything was destroyed. Millions were homeless, millions were refugees. The U.S. led an international effort to help countries rebuild. The U.S. Marshall Plan (1947-1951) was a massive gift to restart Western European economies and societies.

There was so much that obviously had to be done in the short term. Yet the leaders of the shattered countries were not just thinking short term. Each of them used a significant portion of the Marshall Plan funding to establish national health systems. One irony never mentioned in the debate about trying European-style universal health care in the U.S. is that U.S. funds were used to create these very plans.

Today we face the COVID-19 crisis. Schools have closed, and are unlikely to re-open until September, at best. There has been a lot of discussion of how to use distance education to help students now, but only recently has there been much talk about what to do when schools re-open to make up the losses. I wrote a recent blog suggesting schools accelerate the achievement of students who have lost ground in basic skills, as well as those who had problems before schools closed and are now in greater difficulty. I suggested providing well-trained teacher assistants with college degrees to use proven tutoring approaches to accelerate student achievement in reading and mathematics. According to evidence, experience, and common sense, large scale, small group tutoring programs, and other proven methods, should enable struggling students to make substantial gains, erasing deficits from the COVID-19 closures.

But why should we stop there? If it is indeed possible to make a big difference in the performance levels of whole schools using proven cost-effective methods, why should we stop?

Time-limited solutions to the educational damage done by the COVID-19 school closures will not make the difference that needs to be made. Getting back to the status quo is not sufficient. Proven strategies capable of rapidly bringing students back to where they were will also demonstrate how schools can produce gains that go far beyond healing the specific damage due to the crisis.

The Marshall Plan helped Western Europe overcome its losses, but also to establish sustainable systems that continue to ensure the health of their populations 75 years later. In the same way, our solution to the educational impacts of the COVID-19 crisis could help establish a new basis for success for millions of children. Seventy-five years from now, wouldn’t it be wonderful if people recalled that in 2020, a worldwide pandemic finally shocked American education into solving its fundamental problems?

COVID-19 and School Closures: Could Summer Help?

If there is one educational benefit of the otherwise dismal experience of closing virtually all of America’s schools in response to the COVID-19 pandemic, it is this: I’ll bet parents are developing a lot of respect for teachers. I’m hearing a lot about parents finding out that online lessons are no substitute for capable, in-person teachers.

Because of the essential health need to reduce contacts among students and school personnel, schools all over the U.S. have closed. School leaders are scrambling to provide on-line coursework. It is difficult everywhere to go from zero to online in a very short time, but in schools in high-poverty areas, where many or most students lack home computers or reliable internet access, it is well-nigh impossible. But even if every student had a working computer and internet access, there seems to be widespread use of computerized worksheets, and other uninspiring content. In some schools and districts, in which online work is already well used and computers are universally available, the situation is surely better, but even there, online all day every day is no substitute for in-person teaching. Very conscientious and self-motivated students, the kind who already use Khan Academy just for fun, are probably thriving, but such students constitute a small minority, even in the finest schools.

School closures are likely to extend into May, leaving little if any of the regular school year for things to return to normal. Two states, Kansas and Virginia, have already announced that schools will not re-open before the end of the year, and others will surely follow.

The Summer Solution

In light of the realities we face, I think most schools are struggling to teach all of their children during the school closures. Parents are doing their best, as are some students, but nationwide, trying to keep schools going as they always have, except online, is not a satisfying solution.

I have an alternative solution. It has two simple steps.

  1. As soon as feasible, declare schools to be on break. Instant vacation.
  2. When it is safe to open schools, do so. Hold an in-person two-month session, starting (let’s say) on June 1 and running through the end of July.

During the instant vacation, provide parents and students with a menu of engaging activities that are fun, engage students’ energies and curiosity, and optional. These could focus on science, social studies, writing, art, music, and other subjects often blog_4-2-20_masks_500x343given short shrift during the school year.  These would be facilitated by teachers; in my experience, every school and district has many teachers who are crazy about one or more topics that they rarely get to talk about in school.  Teachers may be Civil War reenactors, world travelers, art experts, amateur musicians, or published writers, even if those are not the topics they teach.  In three days, max, any school district could find extraordinary people with fierce passions for something they want to share with kids. Students might be given a choice of activities, and they might choose to do none at all. It’s vacation, after all. The reason to have these activities is to give students shut in at home useful and interesting things to do. I’m sure there are loads of great online activities already out there that are rarely used because of the lack of time for such activities in the regular school year. Imagine any of the following, facilitated by teachers who love these topics:

  • Online trips to faraway places or to periods of history
  • Online book clubs in which students could choose topics they’d like to read about and then discuss age-appropriate books on them with others from all over their school, district, or state.
  • Science clubs, in which students could explore topics of their choice in groups from all over. One interesting topic: epidemiology.  Science clubs could find out everything there is to know about space travel, or the science of music, or the science of sports.
  • Writer’s workshops, in which kids from all over could enroll in groups working on writing their own mystery stories, fantasy stories, sports stories, or biographies of famous people.  That’s how the Bronte sisters learned to write, shut in in small-town Yorkshire, surrounded by poverty and disease.  They wrote stories with and for each other, throughout their childhoods.
  • Art or music appreciation, history, or techniques
  • How students can get jobs and internships (in normal times)
  • Post-secondary options for secondary students

I think you get the idea. Trying to cover all the usual school subjects in the usual way, but online, is sure to be boring and ineffective for most students. But on vacation, shut in students could select learning activities to do not for a grade, not under pressure from parents or teachers, but to satisfy their own curiosity.

When the crisis is over, presumably in the summer, students could return to school and resume their usual lessons, with in-person teachers.  I’m sure there would be practical difficulties, but I’m willing to bet that this could work, perhaps in some places, perhaps in many. At least it seems worth a try!

After the Pandemic: Can We Welcome Students Back to Better Schools?

I am writing in March, 2020, at what may be the scariest point in the COVID-19 pandemic in the U.S. We are just now beginning to understand the potential catastrophe, and also to begin taking actions most likely to reduce the incidence of the disease.

One of the most important preventive measures is school closure. At this writing, thirty entire states have closed their schools, as have many individual districts, including Los Angeles. It is clear that school closures will go far beyond this, both in the U.S. and elsewhere.

I am not an expert on epidemiology, but I did want to make some observations about how widespread school closure could affect education, and (ever the optimist) how this disaster could provide a basis for major improvements in the long run.

Right now, schools are closing for a few weeks, with an expectation that after spring break, all will be well again, and schools might re-open. From what I read, this is unlikely. The virus will continue to spread until it runs out of vulnerable people. The purpose of school closures is to reduce the rate of transmission. Children themselves tend not to get the disease, for some reason, but they do transmit the disease, mostly at school (and then to adults). Only when there are few new cases to transmit can schools be responsibly re-opened. No one knows for sure, but a recent article in Education Week predicted that schools will probably not re-open this school year (Will, 2020). Kansas is the first state to announce that schools will be closed for the rest of the school year, but others will surely follow.

Will students suffer from school closure? There will be lasting damage if students lose parents, grandparents, and other relatives, of course. Their achievement may take a dip, but a remarkable study reported by Ceci (1991) examined the impact of two or more years of school closures in the Netherlands in World War II, and found an initial loss in IQ scores that quickly rebounded after schools re-opened after the war. From an educational perspective, the long-term impact of closure itself may not be so bad. A colleague, Nancy Karweit (1989), studied achievement in districts with long teacher strikes, and did not find much of a lasting impact.

In fact, there is a way in which wise state and local governments might use an opportunity presented by school closures. If schools closing now stay closed through the end of the school year, that could leave large numbers of teachers and administrators with not much to do (assuming they are not furloughed, which could happen). Imagine that, where feasible, this time were used for school leaders to consider how they could welcome students back to much improved schools, and to blog_3-26_20_teleconference2_500x334provide teachers with (electronic) professional development to implement proven programs. This might involve local, regional, or national conversations focused on what strategies are known to be effective for each of the key objectives of schooling. For example, a national series of conversations could take place on proven strategies for beginning reading, for middle school mathematics, for high school science, and so on. By design, the conversations would be focused not just on opinions, but on rigorous evidence of what works. A focus on improving health and disease prevention would be particularly relevant to the current crisis, along with implementing proven academic solutions.

Particular districts might decide to implement proven programs, and then use school closure to provide time for high-quality professional development on instructional strategies that meet the ESSA evidence standards.

Of course, all of the discussion and professional development would have to be done using electronic communications, for obvious reasons of public health. But might it be possible to make wise use of school closure to improve the outcomes of schooling using professional development in proven strategies? With rapid rollout of existing proven programs and dedicated funding, it certainly seems possible.

States and districts are making a wide variety of decisions about what to do during the time that schools are closed. Many are moving to e-learning, but this may be of little help in areas where many students lack computers or access to the internet at home. In some places, a focus on professional development for next school year may be the best way to make the best of a difficult situation.

There have been many times in the past when disasters have led to lasting improvements in health and education. This could be one of these opportunities, if we seize the moment.
