Digital Electronics (ED)
First year of the bachelor's degree in Telecommunications
My idea of teaching
‘Teaching’ is the purposeful creation of situations from which motivated learners should not be able to escape without learning or developing

The basis of student-centred learning
So, I’m going to make you responsible of your own learning …
The learning objectives of Digital Electronics
Specific content +
+ teamwork + communication skills + self-directed learning + third language
Yes! You can learn them all by active techniques like:
Cooperative Learning and Problem-Based Learning
(but not by traditional lecturing!)
cross-curricular skills at level 1 of competence:

You will always know exactly what to do and how to proceed …
Problems will be very guided at the course
beginning and more self-directed towards the
course end
Format of a regular cooperative session
Classrooms with mobile tables
About the classes…
Base groups of 3 students
About the exercises … Motivation
Example
Controlling a storage tank system for a pancake syrup manufacturing

Example
Real-world problems instead of pure academic exercises
http://epsc.upc.edu/projectes/ed/problemes/problemes_PA/Problemes_PA.htmhttp://epsc.upc.edu/projectes/ed/problemes/problemes_PA/Problemes_PA.htm
Motivation
Activating a motor by a 4-digit personal pin
Students see how their designs actually work (in the simulator or using training
boards)
Example of an application project
A digital clock
http://epsc.upc.edu/projectes/ed/ED/grups_classe/07-08-q1/1BT4/07-08-Q1-1BT4.htm (EX7)
Deep learning (content connected throughout the course) Enables whole class collaboration Enable content coherence the same problems can be used again in advanced courses to enhance content learning (technology update using VHDL - FPGA or µC)
Student assessment
• You exercises will be regularly corrected and feedback to your cooperative group for improvement (everything will count for the final mark)
(So, there is no need anymore for classic final exams)
• Assessment is another learning activity integrated in the course dynamics

You can read all the information in the ED course Web

Everything from the last 7 years is here: theory – examples – exams – references –
documents – chips – software - etc.
So, let’s start looking at the first exercise (EX1)http://epsc.upc.edu/projectes/ed/ED/grups_classe/08-09-q2/1BT5/EX/EX1/ED_Curs_08_09_Q2_1BT5_EX1x.pdf
