It is published three times a year and informs you about new media as well as current studies, events and portals from the worlds of OER, education, and STEM.

Teaching from home and homeschooling

School closures are very challenging for all of you. In addition to the about 4,000 OER for STEM lessons, the Media Portal offers useful functions that can support you in networked teaching and learning with your students and their parents. Have a look to the most important ones here.

Digital materials under open license (OER) help a lot to support each other and to encourage the exchange between us: they may be modified, augmented with your own content, and shared. It’s legal, worry-free, and easy. Our quality-checked OER for STEM lessons are interdisciplinary, for all types of schools and grade levels, ranging from detailed texts and short videos, to experiments and interactive formats, to complete packages on various topics. They’re available for teaching and self-learning.

But the Media Portal can do even more to support you now:

Communicate easily with your class and their parents

Create personal bookmark lists where you collect the individual media files of your choice. You can share them with other teachers, students, or parents easily and conveniently at the click of a button. You can add and remove individual media files, add a descriptive text, and also limit the availability to any time period you select. Go to the instructions

Look for the blotch: Self-learning media for your class

The self-learning offering follows a multimedia, diverse approach. Within the media and topic packages for teachers, appropriate materials are identified with the “student’s blotch” and can be forwarded directly to your students.

Experiments, puzzles, tests, educational games, and explanatory videos are found in a separate student's area – let the pupils explore this area independently or conduct experiments with their parents.

Find suitable content quickly and easily

Which media lend themselves to your work with your class at this special situation? Teacher instructions and detailed guidelines provide an overview of the individual media and possible usage scenarios. This enables you to quickly decide which worksheet is currently particularly suitable.

Also take a look at our media selection for teaching from home:
In the next few weeks you will regularly find here new tips on how to use our media.

COVID-19! How can I protect myself and others?

The Smithsonian Science Education Center has developed a new rapid-response guide for youth ages 8–17. The guide, which is based on the UN Sustainable Development Goals, aims to help young people understand the science and social science of COVID-19 as well as help them take actions to keep themselves, their families and communities safe.

The guide “COVID-19! How can I protect myself and others?” was developed in collaboration with the World Health Organization (WHO) and the InterAcademy Partnership (IAP), and is part of the Smithsonian Science for Global Goals project. The guide is free and available to youth in more than 20 languages.

Through a set of seven cohesive student-led tasks, participants engage in the activities to answer questions previously defined by their peers. The questions explore the impact of COVID-19 on the world, how to practice hand and respiratory hygiene and physical distancing, and how to research more information about COVID-19. The final task teaches youth how they can take action on the new scientific knowledge they learn to improve their health and the health of others. Each task is designed to be completed at home, but could be completed in school with a teacher’s guidance.

The guide includes updated research, activities, quotes from scientists and frontline public health officials, and physical and emotional safety tips on COVID-19. It also integrates inquiry-based science education with social and emotional learning and civic engagement.

Comic strip from Welthungerhilfe: No chance for corona

Amina and her friends are stuck at home. Instead of playing together outside or going to school, they are trapped with their parents all day long, often in confined spaces. A comic strip and a video from Welthungerhilfe for children and young people age 10 and older explain the coronavirus and the associated restrictions and preventive measures.

Although children and adolescents are not likely to become seriously ill with COVID-19, they are massively affected by the corona pandemic. Why is it so important to stay at home, maintain proper distance, and wash their hands regularly? What is corona and how is the virus transmitted? Understanding this and knowing how to protect themselves and others helps the young readers deal with the difficult situation. The clearly designed comic strip sensitively addresses the young people’s questions and concerns, explains why normal life is so drastically restricted at this time, and provides tips for preventing the spread of the virus.

The comic was developed by the German aid organization Welthungerhilfe and WASH United in conjunction with the Institute for Hygiene and Environmental Medicine in Berlin, and it can be downloaded free of charge. It may be used, reproduced, and disseminated for non-commercial purposes without limitation. Translation into various African languages such as Arabic, Kiswahili, and Somali is planned. The story of the four friends is also available as a YouTube video.

Comenius EduMedia Seal for the Media Portal

Great joy for our education team: The Gesellschaft für Pädagogik, Information und Medien e. V. was very impressed with the quality of our media and our commitment to high-quality STEM lessons, and has honored the Media Portal with the prestigious Comenius EduMedia Seal.

“It makes us proud to receive this award for the Media Portal, which we care about very deeply,” said Corinna Hartung, project manager of the Portal. “It confirms our commitment to support teachers in designing innovative, digitally enhanced lessons with quality-tested media. This award will certainly help the Media Portal become even better known, and the educational media, the teacher handouts, and the method pages will be used even more frequently.”

The number of users of the free Media Portal already nearly doubled last year. One reason is certainly the fact that all materials are offered as Open Educational Resources (OER). This is an advantage especially in diverse classrooms, because it allows teachers to adapt, individualize, and jointly enhance the OER to meet their teaching and support needs without violating the law.

About the Comenius EduMedia Awards
The Gesellschaft für Pädagogik, Information und Medien e. V. is presenting the Comenius EduMedia Awards for the 24th time this year. Its goal is to promote outstanding digital educational media as well as teaching and learning management systems. To ensure independent evaluation, a jury of European educational experts from the Institut für Bildung und Medien assesses the multimedia products.

New look, new content, exclusively OER

The Media Portal relaunch is complete. What’s unchanged: more than 3,500 quality-controlled teaching materials for STEM education. What’s new: We now rely entirely on OER, have broadened our outreach beyond teachers to include students, offer tips for integrating the media into teaching methods … and much more.

Dear users of the Media Portal,
We have redesigned the Media Portal for STEM teaching - from today on it is purely an OER (open educational resource) portal. Our goal is to organize the Media Portal to be more attractive, more informative, and more useful for you. We’re sending you this letter to inform you about the changes to the Media Portal. Your opinion is important to us and we’re grateful for your feedback, which you can send to

How time flies! We went online with the portal for the first time in May 2009 with 600 media on the topics of energy, the environment, and health. Since then, our media offerings have continually expanded. In 2015, we officially joined the OER movement, meaning that all the materials we create can be downloaded, edited, and shared. The Media Portal currently offers over 3,500 OERs for use in science and technology subjects. The media are available in German, English, and Spanish.

Your use of the Media Portal encourages us in our work!
So far we have counted ...

  • 204,615 live views and
  • 47,412 registered users from 120 countries

Here is a brief summary of the novelties to the Media Portal

  • On the Media Portal, you will now find exclusively OERs, which means that you can download, edit, and share all media without registering. In the future, you will no longer be able to access older media on the Media Portal that were not available under a free license. However, we’re in the process of converting more and more media to OER.
  • When you search for media in the future, you’ll be able to decide whether you want to search for media packages or individual media files. In addition, we have improved our filtering and sorting functions so that you can quickly find what you’re looking for.
  • You’ll be able to store and manage media and media packages in personalized bookmark lists in the future. The bookmark list function allows you to view, download, and easily share grouped media with colleagues or students. You can maintain different bookmark lists for individual classes.
  • In the “Methods” area, you will find information about selected teaching methods and forms of learning for science and technology education, such as web-based training on “Service learning in STEM subjects.” Sample materials are linked for implementation of the methods.
  • There will be a separate student area with a selection of suitably prepared media on the topics of energy, the environment, and health for browsing, trying out, or experimenting.

In the “News” area and in our newsletters, we will continue to provide you with current information about OER, interesting events, and tips for other portals.

We hope you enjoy browsing and reading, and we look forward to receiving your feedback!
