TORQUEs: Riding the MOOC wave to benefit on-campus courses<br />

Volk Benno, Reinhardt Andreas and Osterwalder Koni<br />

Production of TORQUEs<br />

In Spring Semester 2013, ETH produced its first three<br />

TORQUEs, with the intention of testing out various video<br />

types and learning settings (see Table 2). The first<br />

TORQUE was an independent learning course that<br />

taught the use of a statistical tool. This TORQUE is based<br />

on screencasts and tests, and allows students to apply<br />

theoretical knowledge in a standard statistics package<br />

without any further support. The second TORQUE, on an<br />

economics subject, was produced on a tablet where the<br />

instructor was able to add handwriting and highlighting<br />

to PowerPoint slides. This TORQUE serves students as<br />

preparation for each lecture, where face-to-face classes<br />

have now been replaced by more interactive and engaging<br />

scenarios. The third TORQUE, on solid-state physics, is<br />

similar in concept but uses videos produced with a visualizer<br />

and handwritten slides. The face-to-face activities of<br />

the course now comprise discussions and debates on scientific<br />

concepts. Experiments are also performed during<br />

classes. All three TORQUEs went online in Fall Semester<br />

2013.<br />

The three new TORQUEs are compulsory courses within<br />

BSc curricula. Two are courses for very large classes.<br />

The economics course was previously taught in a blended<br />

learning scenario, meaning that a relatively large online<br />

component plus over 50 tests and a wealth of additional<br />

material could be deployed rapidly because many of these<br />

resources already existed. The statistics course, on the<br />

other hand, comprises the same amount of video time but<br />

around half the number of tests, because these were all<br />

developed from scratch. In the physics course the exercise<br />

series were similar to those previously used in the class,<br />

while nine specific quizzes were developed to check theoretical<br />

understanding. The initial motivations for producing<br />

these TORQUEs differed. They were, for the physics<br />

course, the lecturer’s interest in innovation; for the economics<br />

course, a vision for transforming the face-to-face<br />

lecture; and for the statistics course, the wish to achieve<br />

a specific learning objective (apply theory to software<br />

package R) not otherwise possible. The three TORQUEs<br />

deployed completely different video styles. The statistics<br />

course used a typical screencast setting, where the<br />

course designers demonstrated software functions and<br />

introduced exercises on the computer screen and then<br />

recorded it all on video. They wanted flexibility, producing<br />

material in their offices on their own laptops and on<br />

borrowed equipment (headsets, recording software).<br />

The economics clips comprise regular PowerPoint slides<br />

annotated by the author with the help of professionals in<br />

an ETH video studio. The clips for the physics TORQUE<br />

were produced using a visualizer setup installed in the designer’s<br />

office. Setting up and managing these three video<br />

types was very time-consuming for the ETH multimedia<br />

services unit, which is responsible for video production.<br />

The big challenges were the spatial distribution of production<br />

and the different needs and expectations of the<br />

course designers.<br />

A key lesson from these first TORQUEs is that a successful<br />

course requires the tight integration of three main<br />
