“…Our findings are more in line with the results of the study by Kala and Tomcsányiová (2009) who also found that there were no significant differences in the performances of boys and girls on Bebras test scores. Also, the findings corroborate the assumption that Bebras tasks are equally engaging for both girls and boys (Dagienė et al, 2017;Izu et al, 2017). Atmatzidou and Demetriadis (2016) claimed that age and gender relevant differences occured when evaluating students' scores in the various specific dimensions of the CT skills model.…”

“…Bebras tasks are presented either as multiple choice or interactive, and both formats are carried on the computer. Interactive tasks provide a scene or diagram on the screen and require the use of the computer to perform the task actions, while the multiple choice items can be easily implemented without the use of the computer (Izu et al, 2017). That is, these tasks do not require the use of any software or specific technical knowledge.…”

“…It was claimed that Bebras tasks were not gender-biased, that is; they are assumed to be equally engaging both for girls and boys (Dagienė et al, 2017;Izu et al, 2017). However, some studies found that boys were more successful than girls (Hubwieser & Mühling, 2015), while in others, girls' performance was better than boys in Bebras challenges (Dagienė et al, 2014).…”

This study investigated the role of using unplugged computing activities on developing computational thinking (CT) skills of 6th-grade students. The unplugged computing classroom activities were based on the Bebras challenge, an international contest that aims to promote CT and informatics among school students of all ages. Participants of the study were fifty-three 6thgrade students from two public middle schools in Istanbul. The unplugged computing activities involved the tasks with three different difficulty levels covering the CT processes found to be common in CT definitions in the literature. To evaluate students' CT skills, two equivalent tests were constructed from Bebras tasks considering the same parameters (difficulty levels and CT processes). The results showed that students' post-test scores were significantly higher than their pre-test scores. There were not any significant differences between students' scores in terms of gender, and there was no interaction effect between students' CT scores and their gender.

“…In section 6.1 we will analyze some of these tasks for age group VI more in detail. Izu, Mirolo, Settle, Mannilla, and Stupurienė (2017) make a similar analysis for the 2014 and 2015 contest in five countries. They use the rank match to see how well the difficulty level was predicted; the outcomes are between 40% and 72%.…”

Predicting the difficulty level of a task on the concepts of computer science or computational thinking, like in the Bebras Challenge, proves to be really hard. Question difficulty breaks down in content difficulty, stimulus difficulty and task difficulty. Several instruments are suggested to predict the overall difficulty level, like using a questionnaire or a rubric; these instruments are applied on the data of a recent contest and proved useful. Relative scoring could also turnout helpful. Especially on content difficulty easy applicable solutions are lacking.

The Bebras Challenge is an International Challenge on Informatics and Computational Thinking (CT). The goal of the challenge is to make students interested in Computer Science (CS) and CT. The authors let students participate in Bebras in regular Informatics classes at a high school in Japan. Not only involving the challenge, but we also implemented a learning activity which students create original Bebras-like problems. The learning activity aims to make students recognize that materials for algorithmic thinking are around them. Most of the students worked well and produced idea full problems. They created many great works. And some of them were selected as Japanese representative questions for the International Bebras Task Workshop by the Japanese Committee for the IOI, which conducts the Bebras Challenge in Japan. Some of them were used in the actual Bebras Challenge. In this report, we show the students' original questions and discuss the educational effect of this learning activity.
