1. History Academic year 2011-1012 Joining two institutions FCSE First semester Structural programming
language: C Second semester
OOP language…? C++ or Java Why not both of them?
YES
![Page 4: Experience with Two OOP languages in one course](https://reader035.fdocuments.net/reader035/viewer/2022062501/56816468550346895dd6523d/html5/thumbnails/4.jpg)
2. Teaching Methodology … Highly interactive face-to-face style of teaching. Every teaching unit is prepared and performed
with PowerPoint slides, that contain the teaching essence planned for the week.
Each theme is accompanied with parts or complete code of a given problem.
The slides contain questions and programming puzzles - parts of a code of a given problem. simple OO problems, convenient to use for
discussions and mutual exploring towards the solution.
![Page 5: Experience with Two OOP languages in one course](https://reader035.fdocuments.net/reader035/viewer/2022062501/56816468550346895dd6523d/html5/thumbnails/5.jpg)
… and Learning Design 2 hours lectures, 2 hours theoretical and 2 hours of
lab exercises per week. The lectures cover the basic principles of OOP,
supported by code parts for illustration. The theoretical exercises expose the students to
problems that are simple enough to be analyzed during the 2 hours, but also illustrative and realistic to be interesting.
For the lab classes, the students are divided in groups of 20. They solve programming problems that are graded
weekly, and form the part of the course final grade.

3. The week-to-week experience First – confusion, how it will be like ???? First 6 weeksC++ Structural C++ Classes, objects, constructors, destructors Operator overload Inheritance, abstract classes Virtual functions, Polymorphism Multiple inheritance
FIRST partial exam – C++
![Page 12: Experience with Two OOP languages in one course](https://reader035.fdocuments.net/reader035/viewer/2022062501/56816468550346895dd6523d/html5/thumbnails/12.jpg)
3. The week-to-week experience Next 5 weeks JAVA The same OOP topics
But with JAVA specific feauters Garbage collector, polymorphism,
downcasting, upcasting, exceptions
SECOND partial exam - Java
![Page 13: Experience with Two OOP languages in one course](https://reader035.fdocuments.net/reader035/viewer/2022062501/56816468550346895dd6523d/html5/thumbnails/13.jpg)
Main benefit We could emphasize the differences
between the two languages Students showed great interest
![Page 14: Experience with Two OOP languages in one course](https://reader035.fdocuments.net/reader035/viewer/2022062501/56816468550346895dd6523d/html5/thumbnails/14.jpg)
Exams? Always two OOP problems
C++ Java Equally evaluated, 50% each
![Page 15: Experience with Two OOP languages in one course](https://reader035.fdocuments.net/reader035/viewer/2022062501/56816468550346895dd6523d/html5/thumbnails/15.jpg)
But, what do the students think? Is the workload overwhelming? Do all the students feel the same? Is it hard to learn two different OOP
language syntaxes in one semester?

Answers from three different student profiles
1. The most popular answer among the ALL students
2. ‘The Best’ students answers Passed the Structured language course
from previous semester Showed good results on the first partial

Showed <60% on the first partial exam Some of them didn’t pass the SP course

Q7 Mostly mentioned answers
Liked the organization of the course The course team was highly rated Learning two languages was too
difficult (about 35% of the answers) Fancied the female assistants

Passed the course, two generations 2011/2012 2012/2013 ~100 students, one group,
‘independently drawn’ objects According their surnames

Second generation 2012 / 2013 Only one exam session so far (june)
August + January to go 119 in the group So far 35% has passed the exam 10 (A) – 12 9 (B) – 4 8 (C) – 9 7 (D) – 7 6 (E) - 9

Conclusions We believe that this dynamics suite the
students and they are well prepared to continue with the Algorithms and Data structures in the 3rd semester, as well as with the courses about the advanced programming on a different platforms
According the questionnaire, it is not too demanding to have two OOP languages workload
