23. 6th Workshop "SEERE", Ravda, 18-23 September 2006 23 Threads by Ioan, Temisoara  Topic for 2 nd year students  More difficult for students then Klaus’ presentation  Experiment results – part of another presentation

25. 6th Workshop "SEERE", Ravda, 18-23 September 2006 25 Conclusion  The main impression is that the major goal of the Berlin course is to offer a student a clear overview of the OOP using Java  NS course goal, on the other hand, is to deeply involve students with the Java programming language specifics

26. 6th Workshop "SEERE", Ravda, 18-23 September 2006 26 Conclusion  Berlin teaching material More interesting Much more easy to follow Put stress on the difference between OOP and other programming paradigms Clearly shows the difference between Java and Pascal, C Introduces some basic data structures, like stack  NS teaching material More compact Student is forced to struggle with terminology Put stress on the Java programming language specifics More detailed Students prefer this way of presentation  Most of them like to minimize home work

27. 6th Workshop "SEERE", Ravda, 18-23 September 2006 27 Source code in Berlin Students in Berlin get the source code of the Java examples in advance.  They can run the program before the lecture.  In that way, the slides did not contain the source code in all details.  Students are expected to bring along the printed source code to the lecture.  This concept, however, is not so easy to accomplish in a lecture. Conclusion: The opinion of the students of Novi Sad is right: It is easier to have all information (source code) collected in one presentation file.

28. 6th Workshop "SEERE", Ravda, 18-23 September 2006 28 General Conclusions Opinion of Novi Sad students  Students need more explanations -they expect more details, examples – with a lot of code.  Animations and effects are good, but the fact that there isn’t enough code on slides, makes slides less worthy that they maybe should be.  The lectures should have more examples and appropriate source code because it’s much closer to students for understanding.

29. 6th Workshop "SEERE", Ravda, 18-23 September 2006 29 Further steps - General Idea about Course Material  Seems that Berlin and Novi Sad are most interested in preparation of joint material.  Prepare a collection of different topics and concepts (just language, emphasize on OO design and style of programming, advanced topics, some real complex applications,…). Use different versions of the same topics (members of project - Berlin, Novi Sad, Temisoara, Belgrade, Skopje,…, available Internet material) For specific topic make mixture – pick different parts of different presentations – determine responsible person  Prepare complete materials for various stiles of courses Too difficult and time consuming, almost impossible Real solution: Every lecturer can prepare his/her own course based on available pool of different topics (lecturer can make specific selection)
