The environment for learning to program

摘要

We are pleased to present the proceedings of the 10th Annual Conference on Innovation and Technology in Computer Science Education - ITiCSE 2005. We are honored to host this event, in particular as 2005 marks the tenth anniversary ITiCSE conference, a significant milestone in the evolution of this series. The growth and increasing prestige of ITiCSE is testimony to the soundness of the vision - to promote the exchange of international perspectives and advances on questions in computer science education - that motivated the inception of ITiCSE conferences. ITiCSE 2005 will be held in the campus of the Faculty of Science and Technology of Universidade Nova de Lisboa, and is organized locally by the Computer Science Department. It is a fortunate coincidence that this year we are also celebrating the 30th anniversary of the Computer Science Department, and its pioneer role in the launching of the first Computer Science degree in Portugal, back in 1975.The conference programme is full of excitingevents, concerning our common interests in computer science, and including several social events and excursions that will hopefully reveal aspects of the life and the history of Portugal and the region of Lisbon, and the typical Portuguese hospitality. The technical programme includes three keynote speeches, tutorials, working groups, posters, student posters, and "tips & techniques", panels, paper presentations, and exhibits.We are honored to have as invited lecturers Professors Maria Klawe, Joseph Weizenbaum, and Emilio Luque who have kindly accepted to share their deep insights, knowledge and experience with all of us. We are proud that, for the first time, student poster presentations are included in ITiCSE, an opportunity to have undergraduate and graduate students participate in the conference by presenting work that represents the fruit of excellent practice in computer science education. They also represent the future generations of computer scientists and citizens who will project the vision of ITiCSE forward into what will certainly be an exciting and challenging second decade. We believe this is the best way to celebrating the notable anniversary of ITiCSE conference series.ITiCSE 2005 has attracted a record number of paper submissions, making the selection quite competitive, and allowing the acceptance of an increased number of high-quality papers, which represent a diversity of countries. Sixty-eight papers are included in the programme, organized in three parallel tracks, addressing important themes in computer science education.
