Robin Woll, Tino Steffens, Sven Buschbeck, Pascal Berrang,

Daniel Mohr, Matthias Birkenstock, Jrn Loviscach

Quizzes in Videos

www.capira.de-prevent illusion of learning-active interaction instead of just passive consumption-increase amount of invested mental e!ort-create desirable di"culties-wed like to include tons of quizzes, but!!! we know that every quiz is a potential reason todrop out-thats why we try to preserve the flow of the lecture-by asking questions fitting to the context

-we developed a platform that seamlessly integrates quizzes in the video

Embedding in Context

www.capira.de-not only didactic context but ..-embed quizzes into the visual context of the video-elements in the video become interactive


4/13

Quiz Series

master the basics

shuffle the quizzes & answers www.capira.de-at the end of a video-series of 5-10 single choice questions in a row-repeat what you have just learned-randomize the order of answers so you dont remember the correct answer when repeat-randomize the order of the questions itself


5/13

mathslang

evaluate mathematical expressions

(a+b)!= a!+2ab+b!???

showcase

www.capira.de-were focusing on STEM subjects-evaluate text input-string matching and even RegEx are boring or cumbersome-interpret the mathematical expression and compare on the semantic level

Navigation

quickly find what you are looking for

personal progress

reduced to the max, e.g. no need to sign in

course structures and encyclopedia

www.capira.de-reduced to the content the user is actually looking for-no distracting content

Editor

intuitive and efficient

WYSIWYG, Drag&Drop, in-place editing

templating mechanism

expert mode (HTML, JS, CSS)

www.capira.de1) high frequency => for 1 minute of playing time an expert needs about 5 minutes ofediting2) ... therefore we use ... paradigms3) there is a templating mechanism, to quickly reuse standard or frequently used quizzes4) there is an expert mode that enables the author to hack any HTML, JS & CSS code inquizzes

Thats costly but then only your imagination is the limit to possibilities for interactions

Beta Test

10/13

Remedial Course

in Mathematics

100 Videos (15h total playing time)

450 embedded quizzes

more than 350 students

public release as Crash Course in Math

www.capira.de1) in september 2013 we applied Capira to Professor Loviscachs remedial course inmathematics1) from fractions to polynomial division


11/13

Preliminary Results

most students used it

helps to stay focused

public beta test:this is the way to learn

www.capira.de1) ... on a voluntary basis2) with the feedback from students we proved our assumption3) about 20000 unique visitors since september3) we received enough positive feedback to continue working on this idea


12/13

Next Steps

summer semester 2014

Live Editing

tools for statistical analysis

optimization for smart devices

opening the platform for other teachers

www.capira.de1) right now we prepare our plattform to apply it in Professor Loviscachs regular math coursein summerterm2) creating massiv amounts of quizzes takes a lot of e!ort-for an even leaner production we are developing a Live Editor.the Live Editor enables the lecturer to create quizzes during the recording

3) We develop tools to collect data about the learning progress with Capira4) We are already supporting mobile devices.But the user interfaces we use for desktop enviroments does not necessarily carry over tomobile devices. so this requires some optimization5) we are looking for other people who want to use our platformso if youre interested just contact us via our website
