While students undertook their final exam, some of the world’s top computer scientists and researchers offered a glimpse into the future of informatics.
Wednesday morning saw the final IOI conference. Topics ranged from a history of Latvian informatics education to a six-volume analysis of the Olympiad’s journals.
Professor Valentina Dagiene, of Lithuania’s Vilnius University, is on the Olympiad’s International Committee and is responsible for IOI conferences, and was excited about the diversity of topics represented.
“Leaders, committee members and other researchers and teachers join us to listen to our research, to our reports on what we’re doing before and after Olympiads,” Prof Dagiene said.
“In the conference we focus on tasks, grading systems, training students, and what we do in our countries, because here we have over 80 countries.
“And all of these countries have national Olympiads; we train students, we create tasks. This is a kind of academic and training community.”
Belgian computer scientist and PhD student Sébastien Combéfis revealed his website, Interactive Learning of Programming and Algorithm Design Skills (ILPADS), which is designed to support both students and teachers in learning informatics.
“It’s an online platform that can be used by teachers in secondary schools to help teach their pupils what is programming and algorithmic thinking. And to help them learn programming, not directly but through problems,” Mr Combéfis said.
ILPADS incorporates three activities: problems via interactive animation, which are used to build algorithms in students’ minds, finding a solution to the problem by executing a flowchart, and lastly, translating the solution into programming “language”.
“[Students] start with an interactive animation, which they can play with, and try to concretise the idea that they have in their mind,” he said.
“They then have to find a way to solve it by playing and finding a way to communicate it to the computer, because in the end the goal is to have a program written on the computer.”
Mr Combéfis said the website will easily translate to any language and, hopefully, be available by December.
“The goal is to make the teachers in secondary schools do activities with their pupils in class, because there is no course about computer science, at least in Belgium,” he said.
“So there are no secondary school teachers of informatics.”
But the Olympiad itself inspired a number of lectures, notably for the first presenter.
Associate professor Martin Mareš, of Prague’s Charles University, spoke first about a new system designed to help with the management of contest computers via batch execution.
“At most programming contests, which are run in the style of the IOI, there are really hundreds of computers that handle the contest,” Asst Prof Mareš said.
“We have hundreds of contestants with his or her own machine, then we have a lot running in the background operating services like grading, or the competition system and so on.
“And it’s not actually an easy task to manage this amount of machines.”
