The poster presents Bebras informatics tasks based on assembling a program from blocks. These tasks were created in templates based on Papert's microworlds and they familiarize pupils with classical problems used in CS education. In these microworlds, pupils create and run a program which controls a sprite in order to solve a problem emerging from a described situation. We created four such templates. Each template was supplied with its own set of tasks, differing in a topic, a subject matter and graphics. We created more than 100 tasks in total. As pupils go through each task, they repeatedly run the created program while the system provides them with feedback. Some of the tasks were included into the Czech Bebras Challenge, whereas from others we created sets of tasks (like Hour of code) usable in lessons. More than 430 000 pupils aged 10 to 19 from hundreds of Czech schools tried these tasks in 2021, 2022. Our experience shows that these tasks with their interactivity can attract pupils to the contest and thus can contribute to advance pupils' informatics skills.

The multiplication algorithms that we teach elementary students are designed to be efficient, but the conceptual understanding of these algorithms is usually hidden behind this efficiency. For example, one intuitive meaning of multiplication is that of iterated addition. In this paper, we investigate the ways a visual programming activity leverages the concept of iteration to learn multiplication. We report results of a mixed-methods study on second-grade students' use of visual programming and iteration to set up and solve multiplication story problems. We found qualitative evidence that participants gained improved intuition of multiplication as repeated addition and that they made important connections between the programming blocks and multiplication story problems.

Informed by the person–object theory of interest, this study deployed a mixed-method concurrent triangulation design and investigated the impact of major/specialization, gender, and module design on preservice teachers' interest in teaching computational thinking. The study was conducted in a flipped computational thinking module hosted in three sections of educational technology courses at two U.S. institutions. Results from the quantitative analysis showed that preservice teachers who did both Scratch coding and physical computing practices had a higher level of interest than their peers who only did the Scratch coding only. Our qualitative analysis found evidence that preservice teachers' interest differed by their gender and major/specialization statuses. At the end, we provided suggestions for future research and practice for teaching computational thinking in teacher education. © 2019, © 2019 ISTE.

While online communities exist surrounding blocks programming environments, they do not support the type of feedback a novice programmer might receive in a classroom setting. We propose a feedback system in which experienced programmers author feedback and programmatic rules to distribute feedback to novice programmers. Finally, we outline three main considerations for designing systems for online community feedback for novice programmers: community members, the format of the feedback, and how the feedback is distributed at a large scale.

Remaking and reinforcing mathematics and technology with programming - teacher perceptions of challenges, opportunities and tools in K-12 settings

引用

INTERNATIONAL JOURNAL OF INFORMATION AND LEARNING TECHNOLOGY 2020年第5期37卷 309-321页

作者： Humble, Niklas Mozelius, Peter Sallvin, Lisa Mid Sweden Univ Dept Comp & Syst Sci Ostersund Sweden Mid Sweden Univ Dept Informat Syst & Technol Sundsvall Sweden

Purpose The purpose of this study is to analyse and discuss K-12 mathematics and technology teachers' perceptions on integrating programming in their teaching and learning activities, and perceptions on different programming tools. Design/methodology/approach The approach of a case study was used, with data collected from three instances of a professional development programming course for K-12 teachers in mathematics and technology. Findings The findings show that there are perceived challenges and opportunities with learning and integrating programming, and with different programming tools. Many teachers perceive programming as fun, but lack the time to learn and implement it, and view different programming tools as both complementary to each other and with individual opportunities and challenges. Practical implications The practical implication of the research is that it can provide guidance for teachers and other stakeholders that are in the process of integrating programming in K-12 education. Further, the research provides useful information on teachers' experiences on working with different programming tools. Social implications The social implication of the research is that the overall aim of the nation-wide integration process might not succeed if the challenges identified in this study are not addressed, which could have negative effects on the development of students' digital competence. Originality/value The value of the research is that it identifies important challenges and opportunities for the integration of programming. That is, that many teachers perceive the different programming tools available as complimentary to each other, but are hesitating about what is expected of the integration. Findings could also be valuable for future course design of the teacher professional development.

As part of the 3D printing summer course for undergrads in our university, students were introduced to Autodesk Tinkercad as a design tool for creating and editing 3D models. After a brief period of familiarization with Tinkercad, we presented students with Codeblocks, a tool integrated with Tinkercad that enables the creation of 3D models through programming under the blocks model. To our surprise, students started creating complex and lengthy programs to produce original printable 3D objects. We decided to investigate this level of engagement using a questionnaire to collect opinions and experiences from students and a set of metrics to categorize their programming work. The results obtained are presented in this paper along with our conjectures on the causes of the enthusiasm observed with Codeblocks. Three factors seem to have been key in this case: diversity in the composition of the student group, availability of 3D printers to materialize designs, and a relaxed environment where test and failure were common and acceptable.

In this paper we present a novel approach to programme Kaspar, a 22 DOF humanoid robot used for robot-assisted therapy with children with Autism Spectrum Disorder (ASD). The original software used to programme Kaspar was developed to primarily be used in research. However, Kaspar is now used increasingly in other environments, operated by non-roboticists. While Kaspar has a user-friendly interface to be operated by non-programmers, new games or behaviours were mainly created by the research team;thus, we needed to develop an interface that would allow non-roboticists to programme Kaspar. As a solution, we used the Scratch programming language. We tested the Scratch interface with over 170 school children aged 7 to 10, who had the chance to programme Kaspar and give their feedback. In general terms, Scratch was thought to be a fun, useful and easy way to programme Kaspar, and the majority of the children were willing to use it again.

An incremental tide in IoT devices prompts a centralized control system where physical controls such as buttons and knobs can become virtual and centralized via augmented reality: especially headset AR. I conduct a literature mapping to identify gaps and create a front-end based virtual control panel API tool to allow programmers and end-users to rapidly create headset augmented reality-based virtual control systems for physical devices. I probe on how an artificial intelligence back-end aids in such a system in terms of panel creation and automation as well as panel usage and control scenarios. I delve into use cases of the virtual control panel API including mass usage and specialized scenarios. Furthermore, I specify the guidelines for a requirements elicitation study for such a system along with potential points of derivation. Next, I probe into implications and limitations of such a system in terms of artificial intelligence, usage, and precision. My work has implications for programmers and users of a virtual control system backed by artificial intelligence for the purpose of controlling physical IoT devices in mass usage as well as in specialized scenarios.

Playful Programming Products vs. Programming Concepts Matrix

11th European Conference on Game-Based Learning (ECGBL)

A number of Danish primary schools are involved in pilot studies where 1st to 9th grade students work with Scratch and Lego MindStorms in STEM subjects. These games may become part of the curriculum at these schools. Recent research identifies a category of games and toys that support learning to computer program: playful programming. This research also describes a project to bring together different stakeholders (developers, educators, parents and researchers) with a common vocabulary for describing, developing, teaching with and comparing these playful programming products and develops a model of supported programming concepts that can be used to differentiate these products. The model includes programming concepts like operators, procedures, encapsulation, variables and events, but also identifies numerous specialization and sub-specializations of these concepts. This paper aims to use this model to provide educators and researchers involved in pilot studies with an overview of which programming concepts various playful programming products exercise (a playful programming products vs. programming concepts matrix). We also add additional concept specializations and expand on the descriptions of concepts included in the model. Finally we consider how this work can be used to support a crowed-sourced playful programming research program.
