• "...a beautifully executed lesson on the history of the universe" - The New York Times • Winner of the WSA Mobile Award • Top1 iPhone Book App in 10 Countries • Featured by The New York Times (Top10 iPad Apps of the year) • Featured by the American Photo Magazine (Top 10 Photo eBooks of the year) For iPad download - Back in Time Back in Time will take you on a stunning exploration of the history of our Universe, Earth, Life and Civilization. A journey through time where each event is documented with social and historical context, several images, an illustrative timeline and little-known interesting facts. Custom made animations bring those events to life, creating an interesting, immersive learning experience. An imaginary clock will guide you through this quest, proposing a simple analogy: the entire Universe started 24 hours ago. The Big Bang, the source of time and space, is the first event in our journey – the clock reads 0:00 hours. Today, 13.7 billion years later, the clock reads midnight. In between is a sequence of key events that has brought us to where we are today. Explore them, place them in perspective, see how they relate and understand the connections. We invite you to take a step back and see the whole picture. :::: REVIEWS - iPad version :::: "The coolest history textbook you’ll find on the iPad" - Bob Tedeschi, The New York Times “The iPad could use more apps like this one.” - The Daily “...a beautifully executed lesson on the history of the universe and the evolution of life on earth.

iWortarten lässt dich nicht im Stich. Du lernst handlungsorientiert, spielerisch die fünf Wortarten kennen und übst sie. - Nur zum Lernen, keine Spiele, keine Ablenkung - Für Schulen von Lehrperson entwickelt und mit Schülern erprobt - Keine In-App-Käufe, keine Werbung, keine Registrierung - Einfacher Lehrpfad, von vorne nach hinten, vom Einfachen zum Schweren - Lernmodus und Testmodus mit Punktauswertung - Hilfen wie Spicktaste, Wiederholungstaste, korrigieren im Lernmodus erlaubt - Lernen aus Fehlern: Sofortiges Feedback, auch Fehler werden genau kommentiert - Pädagogisch wertvoll, handlungsorientiert. Es wird dir immer geholfen und genau erklärt wenn du einen Fehler machst. So lernst du aus deinen eigenen Fehlern. In einem Satz zeigst du jeweils auf die gesuchte Wortart. Diese erscheint sofort in der entsprechenden Wortartenfarbe. Du erhältst sofort Feedback. Die Punkte werden gezählt. Wenn du Hilfe brauchst, betätige die Spicktaste. Jedes Wort wird dann kurz in der richtigen Farbe gezeigt. Nach jeder Geschichte und am Schluss kannst du die Punktzahl oder die Prozentwertung abrufen. Im Schlusstest sind die Spicktasten und die Wiederholungstasten nicht verfügbar, dafür erhältst du doppelte Punktzahl. Mit der Lern-App lernst du handlungsorientiert die Fünf-Wortarten-Lehre nach Hans Glinz wie sie in Schweizer Schulbücher gebräuchlich ist und übst sie intensiv. Für Lehrer sind die Lern-Apps ein unverzichtbares Hilfsmittel, um Schüler zu motivieren und zu begeistern. Die Inhalte werden auf der kognitiven und der motorischen Ebene vermittelt. Kommentar aus Deutschland (iPad@School): Dabei merkt man der App sehr deutlich an, dass ihr Entwickler Andres Streiff selbst in der Schweiz als Lehrer tätig ist und somit die Anforderungen an solch eine App sehr genau kennt. Für mich als Lehrer in Deutschland wirkt die schweizer Methode im ersten Moment etwas verwirrend, auf den zweiten Blick erkennt man aber schnell, dass sie sich nur wenig von der mir aus Deutschland bekannten unterscheidet. Schüler sollte das allerdings kaum auffallen. Die App ist wirklich liebevoll gestaltet und für ihren speziellen Zweck hervorragend geeignet. Meine Empfehlung hat sie auf jeden Fall!
