5 tips for effective distance learning during school closures

For the foreseeable future, most teachers will be teaching in front of a screen instead of a classroom. For educators who are new to distance learning, it can be challenging to know where to start. So we asked our Certified Innovators, a passionate community of Google for Education experts transforming education across the world, to share their best practices and strategies. 

Continue live teaching online

Marcello Baroni, high school, teacher of graphic design, Scuola d'Arte A. Fantoni Bergamo Italy

With schools closed, our whole school has been conducting distance lessons with Google Meet. That’s 650 students, 22 classes, 30 teachers, 20 tutors, and coordinators all connected virtually, so learning isn’t disrupted. We’ll be using Meet in the future to keep all students connected, wherever they are.

Teachers and students are also finding Google Classroom helpful to stay connected and engaged. Here are tips for using Classroom during periods of high demand. And to avoid connectivity issues, consider pre-recording lessons and posting to Classroom, or use the livestream feature in Google Meet. 

Create digital office hours 

Michael Kaufman, Tech Integration Coach, American School Foundation of Guadalajara

Digital office hours are a great way to ensure remote students still get one-on-one support from their teachers. I use Google Calendar and Hangouts Meet to create digital office hours. The two tools together make it easy to organize your hours and create a space for live interaction between the teacher and students in a distance learning situation.

Here is my YouTube video that guides you through creating digital office hours with Hangouts Meet and Google Calendar. 

Use offline features to support students with limited or no home internet access

Mykel Williams, 7th Grade Math, Baldwin County Alabama

Even if students have limited or no internet access at home, remote learning can be done using offline features for Chromebooks. Our students can still access Drive offline and they can download video lectures from Google Classroom to watch later if they don’t have internet at home.

Build a digital learning hub

Kyle Pace, Director of Technology, Grain Valley Schools

Using Google Sites—a simple website building tool—you can build a central hub for resources, important updates, and reminders can help students stay organized and keep parents and guardians in the loop, too. Students can also use Sites to create digital portfolios and share their work with teachers, guardians, and peers. Our teachers do a fantastic job of using Google Sites to keep parents and students up-to-date throughout the school year. Each team has its own dedicated site with important information and reminders, which helps learning stay on track.

Want to get started with Sites? Check out this tutorial

Provide one-on-one guidance remotely

Abbey Sarault, 9th Grade biology and medical detectives, Abington

If a student is absent, has trouble accessing the internet, or even just needs a refresher on how to do something, videos can be a huge help, especially when students can download and replay them. With the Screencastify extension, it’s easy to record your screen and share the video with students directly in Classroom. You can also use videos to explain new tools and approaches to help students get the hang of distance learning. Here’s how I used ScreenCastify to guide absent students through an assignment

Teach from Home is our resource to help teachers who are teaching remotely. For more distance learning tips and information, follow along on Twitter and Facebook. If you have tips for supporting remote students, share them with us here. And if you’re just getting started using remote learning tools, check out the Teacher Center, where you can find 101 trainings and lots more. 

What’s new in Chrome OS: Easy navigation in Chromebook tablet mode

With the latest Chrome OS update, Chromebook tablet mode is simpler to navigate thanks to new gestures, the launch of Quick shelf, and updates to Chrome browser that are tailored specifically for tablet mode.   


What is Chromebook “tablet mode”?

Chromebooks, which all run on Chrome OS, help you to get things done and keep you entertained. All 2-in-1 Chromebooks work as both a high-performing laptop and a tablet. If you have a convertible Chromebook, fold your screen back on its hinge and your Chromebook transitions to tablet mode. Or if you’re using a detachable Chromebook like the Lenovo Chromebook Duet, then you can fully remove the keyboard to activate tablet mode.


Navigate tablet mode with gestures

We've built new gestures for Chromebook tablet mode, which make it easier for you to navigate using touch. 

Now, to get to your tablet mode’s Home screen, swipe up from the bottom of the screen.

Gesture1

You can also see all the windows and apps open on your Chromebook with a similar gesture. Swipe up from the bottom of your screen and hold at the end of the motion, and you’ll see an overview of the windows and apps running on your Chromebook.

Gesture2

If you’re browsing in tablet mode, you can navigate between web pages faster now. Just swipe from the left side of the screen to go back to the previous page. 

Gesture3

Enjoy more screen space

We’ve redesigned the shelf on Chromebook to give you more space on your screen for windows and apps. Now, when you’re in tablet mode, you can access your pinned apps and other programs that are running from the Quick shelf. To summon the Quick shelf, just make a small swipe up from the bottom of your screen. 

QuickShelf

Even when you’re using Chromebook in laptop mode, the shelf is now more compact to give you more space to focus on your task at-hand. This is especially useful if you’re multitasking with various windows.

Speaking of making the most of your screen space, we’ve also extended picture-in-picture to all Google Play Store apps on Chromebook, even for tablet mode. Now when you’re watching a TV show or video on YouTube, Prime Video, Hulu or other apps, you can minimize the video screen and watch it while you’re doing other things on your Chromebook.


Use Chrome, tailored for tablet mode

This update will allow you to more easily manage Chrome tabs with a touch-friendly tab strip while in tablet mode. When you’re browsing, you’ll be able to open a new tab with a big button, reorder tabs by dragging, and close tabs by swiping up.

This change is coming first to the Lenovo Chromebook Duet, which will be available for purchase within the next couple of months. We’ll then bring the tab strip to other Chromebooks with tablet mode soon.  

TabStrip

We’re also making updates to Chrome OS to keep Chromebooks hassle-free— especially in these moments when technology helps us stay connected to each other.  So we’re listening closely to feedback that Chromebook owners provide on our Chromebook Community to keep adapting our software to the evolving climate.  

Stay tuned for more from us soon. If you're new to Chromebook and want to get up to speed quickly, check out this article for more information and tips for using your Chromebook at home.

Accessibility ideas for distance learning during COVID-19

The massive shift towards distance learning presents many challenges for students, educators and guardians alike. But supporting students who have disabilities or require a hands-on approach in the classroom is an even greater challenge. Educators around the world are putting in long days to find creative ways to support all students in this new setting, especially students with disabilities. Here are some tips on using accessibility features to support all learners.

To help students stay organized and get work done

Distance learning has made it tougher for all students to pay attention and manage their time, and this can be especially hard for students with executive functioning challenges. These tools can hopefully help.

  • Use Calendar reminders to help students remember deadlines, and view due dates in the class Calendar in Google Classroom.

  • Encourage students to organize their assignments in Google Classroom or Google Keep, or in Google Drive

  • Suggest students use Chromebooks in full-screen mode when working on assignments to minimize distractions.

  • Students can use Virtual Desks on Chromebooks or the Dualless Chrome extension for students who may benefit from seeing multiple Chrome windows on a single Chromebook monitor. For example, students can view a video lesson on one side of the screen, and a written assignment on the other side.

  • To help students manage their time, use the Stopwatch & Timer Chrome extension to create large on-screen timers. 

  • Break up lessons into shorter parts, which can be beneficial for students with attention challenges.

  • Instead of doing video calls with the whole class, consider breaking the class into smaller groups, where each group meets one or two times per week. Prioritize 1:1 video calls for students who need it most.

  • For students used to working alongside teaching aides in class, you can create a Google Doc in which students can ask questions and get help in real time from their tutors, family members or support staff.

To help students and parents create a space for learning

Now that many of us are doing everything from home—teaching, learning, playing, and working—finding time for it all can be challenging. But it’s important to help students, especially those with learning challenges, carve out space and time to focus on schoolwork.

  • Dedicate a space (even if it’s small) for learning time only. If possible, avoid spaces near windows, open doors, or noisy areas of homes.

  • Suggest that students with attention challenges sit on swivel chairs, if available, to let off some energy. Fidget toys like spinners can also help students focus during lessons.

  • For students using text-to-speech tools, headphones can be helpful, especially if they’re listening during a video class with other students.

To ensure your lessons are accessible

Many Google tools have accessibility functions built in: 

  • If you’re using G Suite for Education, you can enable captioning in Meet or in Slides. Captions can be helpful for students who are Deaf or have hearing loss, or those learning English—but also students in a noisy home environment.

  • Record your presentations in Meet or tools like Screencast-O-Matic or Screencastify for students to watch on their own as homework. This can help you make the most of live lessons, when you want to encourage as much interaction as possible.

  • Learn from your peers who are sharing stories with Google about engaging students through distance learning. Visit the COVID-19 distance learning resource page and Teach from Home for help.

To learn more and watch some tutorials, watch these videos, our G Suite accessibility user guide or join a Google Group. And find more on the Teacher Center, YouTube, and the Chromebook App Hub. Now is an important time to learn from each other—if you have other ideas, we encourage you to share them via this Google Form to help educators around the world benefit from your experience.

Looking back at last year’s Webmaster Conference Product Summit

As a part of the Webmaster Conference series, last fall we held a Product Summit at Google's headquarters in Mountain View, California. It was slightly different from our previous events, with a number of product managers and engineers from Google Search taking part. We recorded the talks held there, and are happy to be able to make these available to all of you now.

In the playlist you'll find:

  • Web deduplication - How does Google recognize duplicate content across the web? What happens once a duplicate is found? How is a canonical URL selected? How does localization play a role?
  • Google Images best practices - Take a look at how Google Images has evolved over the years, and learn about some of the best practices that you can implement on your site when it comes to images.
  • Rendering - Find out more about rendering, and what it takes to do rendering of the web at scale. Take a look behind the scenes, and learn about some things a site owner could watch out for with regards to rendering.
  • Titles, snippets, and result previews - What's the goal of titles, snippets, and previews in Search? How do Google's systems pick and generate a preview for a page? What are some of the elements that help users decide which page to click in Search?
  • Googlebot & web hosting - Starting with a look at the popularity of different web servers, and the growth of HTTPS, you'll find out more about how Google's crawling for Search works, and what you can do to control it.
  • Claim your Knowledge Panel - Knowledge Panels are a great way for people and organizations to be visible in Search. Find out more about the ways you can claim and update them for yourself or for your business.
  • Improving Search over the years - Are dogs the same as cats? Should pages about New York be shown when searching for York? How could algorithms ever figure this out? How many ?'s does it take to get Google's attention? Google's Paul Haahr takes you on a tour of some changes in Search.

We hope you find these videos insightful, useful, and a bit entertaining! And if you are not subscribed to the Webmasters Youtube channel, here’s your chance!

11 startups addressing global problems—here’s how we’re helping


When we announced our Google for Startups Accelerator on the Sustainable Development Goals (SDGs) in November, we did not foresee how dramatically day-to-day life would soon change. The COVID-19 pandemic and its widespread health, social and economic consequences have made the goal of the program—to help founders build technology to  solve serious issues facing our world—even more pressing. 

We received almost 1,200 applications from across Europe, the Middle East and Africa and—together with an external jury—we carefully evaluated each of these ideas. Today, we’re announcing the 11 startups selected to participate in our inaugural Google for Startups Accelerator on the SDGs. These startups address a wide range of social and environmental challenges, and are working toward at least one of the 17 Sustainable Development Goals outlined by the U.N. 

Apic.ai (Germany) uses honeybees as biosensors in the fight to protect biodiversity. 

Cervest.earth (UK) provides personalized insights on the impact of climatic and extreme events, predicting the risks and effects of climate volatility in real-time, for any location on the planet. 

Ellipsis.earth (UK) uses drone imagery and machine learning to identify and track plastic pollution, aiming to provide a global database of the types of plastic waste found in our oceans, beaches and rivers.

Everimpact (France) combines satellite imagery and ground sensing to monitor air quality and carbon emissions in cities.  

Flare (Kenya) offers software infrastructure and operational support for medical emergency response services in Sub-Saharan Africa.

mDoc (Nigeria) uses a digital platform and in-person hubs to support people living with chronic diseases. 

OKO (Israel) is crop insurance designed for emerging markets, using new technologies in satellite imagery and weather forecasting to simplify and automate claim management. 

Ororatech (Germany) is the first commercial supplier of infrared satellite data for early detection and real-time monitoring of wildfires across the globe. 

Skilllab (Netherlands) uses AI to empower job seekers, such as refugees, to integrate their skill sets into local labor markets.

Solar Freeze (Kenya) is pioneering mobile cold storage units powered by renewable energy for smallholder farmers, to help them reduce post-harvest loss in the developing world.

Wondertree (Pakistan) accelerates cognitive and motor development in children with special needs through movement-based therapeutic and educational AR games. 

Each startup founder will work closely with engineers from over 20 Google teams and other subject matter experts to address product, engineering, business development, and funding challenges. Since this accelerator is focused on sustainability, founders will learn these skills through the lens of the Sustainable Development Goals and relevant partners.

In order to keep the program safe and accessible in light of COVID-19, the first two on-site events will now be digital. Virtual training will cover topics such as creating Objectives and Key Results (OKRs), UX Research & Behavioral Economics, ML Data Pipelines and Data Visualization, SDG innovation for sustainable impact, and Strategies for Social Impact Fundraising. The five-month program kicks off on April 21st, and a second cohort will be selected later in the year.

Google for Startups was created to support those who want to build something better—and that’s exactly what we’ll continue to do, whether online or IRL. These are just a few of the many startups working locally on global solutions, and we’ll continue to bring Google’s resources to this entrepreneurial community.
