WHAT IT’S ALL ABOUT Following on the highly successful WDR augmented reality app covering history from 1933–1945, which was downloaded 1.5 million times, the German broadcaster is releasing its “Die Klima App” (The Climate App). Digital education will never be the same. Use a tablet or smartphone and learn in a thrilling and hard-hitting new way. The app offers a choice of four different modules: - Receive a virtual classroom visit from survivors of the flood disaster in Germany’s Ahr Valley. As they stand face to face with you, they’ll describe how they were trapped by the rising waters and feared for their lives. The augmented reality technology lets you experience the deluge and destruction for yourself. - When you play the Save the Sea game, your classroom turns into an ocean, with plastic waste floating in it. You dive through a portal into the water and use a gripper to fish out the rubbish and earn points. At the end, you’re awarded a medal. There are also bonus bottles with animated information. - Step into a virtual environment and experience the devastating regional forest fire in Gummersbach, Germany, as well as the dangers faced by residents and volunteers during the rescue operations. One firefighter recounts what it was like being up close to the blaze. - Four young people join you virtually in the classroom to talk about the different ways in which climate change has impacted them. Anna is a farmer from Overath whose cows suffer from the heat. In Dinslaken, Aaron is cultivating a forest. Tina lives in Kuckum, a village affected by lignite mining. A Fridays for Future activist, Leonie talks about flooding in Uganda. On top of that, there are facts and additional information (i) on the various topics. We would love to read your feedback and review. Contact us: ar@wdr.de THE APP IN THE CLASSROOM Teachers can access the dedicated lesson plans on various subjects as well as worksheets in the app menu (available only in German). Designed for students aged 13 to 16 years and suitable for inclusive learning groups, the climate app modules lend themselves to varied, interdisciplinary use. FEATURES o By downloading the WDR “Die Klima App”, you can use it offline without worrying about the quality of your network connection. o The app is easy to use and inclusive. o Different people and life stories play an important role. o Climate change is brought to life through interdisciplinary topics. The use of animations in the many factual, informative videos keeps things exciting. o The WDR “Die Klima App” is free of charge. WHAT AUGMENTED REALITY MEANS Augmented reality (AR for short) is a technology that blends the real world with virtual elements, allowing you to place virtual, three-dimensional animations and people in real rooms. This means you can go on a voyage of discovery, exploring and moving around in the virtual environment. Virtual visitors who appear in real-world rooms will tell you their stories. These are short – 1:30 to four minutes – but very intense and very moving.

TeacherTool is a solution for teachers that combines three functions into one - digital calendar, notebook and timetable. TeacherTool was developed in practical use for practical applications and has been setting unrivaled standards in terms of data security, functional scope, ease-of-use and support since 2009. TeacherTool will revolutionize the way your student administration by making it more effective, easier to navigate and more customized. TeacherTool puts all of your key student information right at your fingertips so that it can be instantly accessed and edited. By assigning your own password and using powerful data encryption tools, you will also be able to protect the data against unauthorized access. If, for instance, a student inquires about his or her grade status, you will be able to spontaneously review with the student, criterion by criterion, his or her performance development based on compelling graphics. If a proposed grade is not in compliance with your pedagogic standards, you can make individual adjustments to the grade computation process at your discretion! Do you prefer to use symbols to grade your students’ work? - TeacherTool also has the capability to use symbolic grading systems (including Emojis for your youngest pupils!) The solution can readily convert conventional grades into symbols and vice versa – no adjustments required. If a student provides an excuse for an absence, you will be able to see when the student was absent in TeacherTool right away. Simply click on the identified time frame to excuse the absence. If you have to grade a test, all you have to do is define the number of points for each individual question and TeacherTool will automatically convert them for you. You can even use this tool for other types of assessments, e.g. in physical education. If you want to create a tally sheet for homework, you will find it convenient that TeacherTool treats all types of remarks/comments as tally sheets and that homework is just one of many possible applications. You may also want to record data during lessons in the classroom. Handling this task is one of the special capabilities of the TeacherTool! It knows your class schedule and is very versatile when it comes to making updates: it proposes times of absence to be logged, automatically calculates late arrivals, generates entries into the register and handles lots of other tasks. Do you have to plan and document lessons? Simply use the register to assist you with planning. Attach your digital teaching materials to each classroom hour scheduled or download them from the Cloud anytime you need them! Photograph your blackboard presentations and project the photos to the screen at the beginning of the next lesson to recap and review. Need some help remembering? – Of course there’s a tool for that. Simply take pictures of your students (after obtaining their consent), create an interactive seating chart and set up the TeacherTool to remind you of all organizational matters! TeacherTool is a universal app, i.e. you can install it on all of your iOS devices and use it simultaneously. Via encrypted data transfer, it is possible to synchronize the data between the different devices exclusively via your WLAN connection. Hence, no data is loaded onto external servers and you do not have to register yourself or your students anywhere to be able to use TeacherTool. TeacherTool is far superior to similar competitive products since it offers maximum data security and privacy. TeacherTool is also your best choice because of its expeditious and competent support services, which are at your disposal whenever you have any questions.
