1 Problem-Based Learning: Data Analytics and Machine Learning Techniques for Solving Real- World Challenges Dr Jasmina Lazić, MathWorks 2015 The MathWorks, Inc. 1

2 Teaching in the Classroom: Then and Now 2

3 Workplace: Then The term computer, in use from early 17 th century, meant one who computes : a person performing mathematical calculations, before electronic computers became commercially available. Teams of people were frequently used to undertake long and often tedious calculations. (Source: Wikipedia) 3
