A lecture (from lēctūra ) is an oral presentation intended to present information or teach people about a particular subject, for example by a university or college teacher. Lectures are used to convey critical information, history, background, theories, and equations. A politician's speech, a minister's sermon, or even a business person's sales presentation may be similar in form to a lecture. Usually the lecturer will stand at the front of the room and recite information relevant to the lecture's content. Though lectures are much criticised as a teaching method, universities have not yet found practical alternative teaching methods for the large majority of their courses. Critics point out that lecturing is mainly a one-way method of communication that does not involve significant audience participation but relies upon passive learning. Therefore, lecturing is often contrasted to active learning. Lectures delivered by talented speakers can be highly stimulat

The dynamics of ordinary matter in the Universe follows the laws of (magneto)hydrodynamics. In this course, the system of equations that describes astrophysical fluids will be discussed on the basis of selected astrophysical examples, from the physics of stars, to galaxies and the early Universe.

This course gives an introduction into Solid State Physics (crystal structure of materials, electronic and magnetic properties, thermal and electronic transport). The course material is at the level of Ashcroft & Mermin and is addressed to the 3rd year students in Physics.

The course aims to introduce the basic concepts and results on metric embeddings, or more precisely on approximate embeddings. This area has been under rapid development since the 90's and it has strong impact on algorithms for discrete optimization problems.

Diener & Diener Architects Housing

Alexandre Aviolat, Bruno Marchand

For Diener & Diener Architects, residential architecture is the "foremost and single most beautiful" architectural endeavor, as Roger Diener says himself. For the past fourty years, the resulting buildings have been a veritable recherche patiente for the office and have become outstanding exponents of Swiss architecture. This book comprehensively and systematically documents thirty selected projects and discusses their urbanistic and architectural potential. In their research, the editors Martin Steinmann, Bruno Marchand, and Alexandre Aviolat were able to draw on a wealth of documents from the office as well as on the collected lectures by Roger Diener.

Visual Augmentation of Deictic Gestures in MOOC Videos

Pierre Dillenbourg, Kshitij Sharma

We present an eye-tracking study to compare different modalities for visual augmentations of the teacher’s explicit deictic gestures on a video lecture. We compared three visualizations: 1) hand gestures with a pointer, 2) gaze overlay, and 3) no-augmentation baseline. We investigate the teacher-student pair in a video-based learning context as an abstraction of an expert-novice pair where the goal is to attain a high level of shared understanding. The key phase of having a shared understanding is to have a common ground between the pair. Previous studies showed that explicit deixis plays a major role in initiating and maintaining common ground. This led us to hypothesize that augmenting videos with teacher’s deictic gestures might help students perform better. We found that augmenting the video with teacher’s gaze results in higher learning gain than no visualization. Moreover, gaze visualization also helped students in maintaining longer attention spans than hand gestures.

Looking AT versus Looking THROUGH: A Dual Eye-tracking study in MOOC Context

Daniela Caballero Díaz, Pierre Dillenbourg, Patrick Jermann, Kshitij Sharma, Himanshu Verma

We report the results from an eye-tracking study to show the differences in gaze patterns across the MOOC learners, while they watch a lecture individually as well as when they collaborate on an add-on activity. 98 university students took part in a study where they watched the MOOC video individually and later they collaboratively constructed a concept map. In both phases the gaze data was recorded. We compute two gaze measures: (1) with-me-ness, to quantify how much students follow the teacher during the video lecture, (2) gaze similarity, to quantify how much the pair looks at the same set of objects while collaborating. The analysis shows that both of the measures correlate significantly with the learning outcome. We argue that these results, conforming to our previous findings, indicate that the proposed gaze measures give a fairly accurate proxy to learners’ engagement and performance.
