Dynamic of the course

The course is divided on different modules, described in the time schedule below. Each module is structured in three stages:

Demostration
all students are connected to the main room; goals of the module will be explained by an instructor.
Individual work
students go the breakout rooms they have been assigned and perform the tasks of the walkthrough in the tutorial.
an instructor will be assigned to each breakout room.
Common discussion
on the last 5 minutes of the module, we come back to the general breakout room for discussion of problems found.

Data location

Each module has one or several walkthroughs. The data of the walkthroughs is sometimes synthetic and created on the fly, and sometimes a data set is necessary. In such cases, the text of walkthrough will point to an on-line location where the data can be downloaded.
During this course, the data will be also available in the filesystem, you will not need to download it.

The general repository for the data is:

/d/embo2021/d/dynamo
