For lecturers

Three hours of lecture. Three minutes that stick.

Your students already learn from short videos. teechr turns your slides into one: the key theories named and credited, drawn as they're explained, ending on a question they have to answer. Built on the research on memory — and you have the last word on every line before it's voiced.

    Where it fits

    It won't replace your lecture. It keeps it from fading.

    Short video is where your students' attention already goes, and the typical viewer stops by about six minutes, however long the video (Guo, Kim & Rubin, 2014). teechr works in that format without dumbing down: every key concept keeps its name, its claim and its author. Send one before class, after class, and before the exam.

    What's remembered across a course week A schematic. A short video before class gives a small head start. The lecture raises what is remembered sharply. Left alone, it falls away steeply. With a two-minute review after class and another before the exam, each fall is shallower and more is kept. what's remembered your lecture lecture alone Before class Lecture After class Before the exam
    a teechr video with reviews lecture alone A schematic, not data: the shape of the forgetting curve (Ebbinghaus, 1885) and of the spacing effect.

    How it works

    Most of a lecture has to go. teechr chooses what stays.

    1. Upload your deck

      A .pptx or .pdf. Speaker notes count — that's where the explaining lives.

    2. teechr distils it

      It keeps the named theories your lecture stands on, cuts the admin, and checks every name and citation against your slides.

    3. You approve, then share

      Edit any line before it's voiced. Students get a private link that plays in any browser.

    • Only what's in your deck
    • You approve every word
    • Private, unlisted links
    • Landscape or phone-shaped

    Why it sticks

    Every scene draws the shape of its idea.

    Pictures that only decorate make a lesson more liked, not better learned (Sung & Mayer, 2012). So each scene gets a diagram of how its idea is built — a comparison, a sequence, a set of kinds. Try them:

    • Named and credited

      Each key concept's headline is the theory's own name — the term the exam uses — credited as your deck credits it.

    • Said, not printed

      The narrator explains; the screen shows the diagram and the name, never the sentence being spoken. Printing it as well makes people learn less.

    • Ends on a question

      The video stops until they answer. Recalling an idea fixes it better than reading it again.
