Abstract

Indonesia is a full member of International Bebras Community and regularly perform the annual Bebras Challenge since 2016. The tasks for the Indonesian Bebras Challenge are taken and adapted from International Bebras Task pool, and each of the tasks is related to informatics and Computational Thinking (CT). We explore and analyze the Indonesian Bebras Challenge 2021 data to find interesting insight into Indonesian student’s competencies in informatics and computational thinking, the suitability of the selected Bebras Tasks difficulty level for each age group, and the relation between participants’ score and time duration in completing Bebras Challenge. The data exploratory has been done with statistics and data visualizations. We found that Indonesian students need to learn more about informatics and CT. The difficulty level of the Indonesian Bebras Challenge for elementary school students is still in accordance with Indonesian students’ competency. In contrast, the Bebras Challenge difficulty level for junior and senior high school is higher than the students’ competency. By analyzing the time duration of each participant completing the challenge, we also found some dishonest attitude presumptions during the online Bebras Challenge. We discover some suggestions for the improvement of Indonesian Bebras Challenge event as a means to improve Indonesian students’ informatics and CT skills.
