Informatics in Education

Computational thinking (CT) is widely recognized as a key 21st-century competence, yet its integration across disciplines remains unclear for many educators. This study explores how prospective teachers identify and express CT through scripts representing computational processes in school subjects of their choice. The challenge of integrating CT in teacher preparation programs in non-STEM-related fields is also addressed. Using a mixed-methods approach, we analyze projects and accompanying reflective analyses from 375 prospective teachers who created Scratch-based scripts aligned with computational processes in STEM and non-STEM subjects. Data analysis yielded a taxonomy of pedagogical strategies reflecting diverse instructional approaches. The study underscores the value of guided, discipline-specific CT activities in teacher preparation programs and highlights how script development of computational processes fosters both subject-matter understanding and computational thinking. The results suggest holistic lens in evaluating CT integration and offer evidence-based insights for embedding CT meaning-fully into teacher preparation programs across disciplines.

Automatic assessment of programming exercises is typically based on testing approach. Most automatic assessment frameworks execute tests and evaluate test results automatically, but the test data generation is not automated. No matter that automatic test data generation techniques and tools are available.

The paper describes some possible ways how to improve Olympiads in Informatics. Tasks in Olympiads are small models of programming tasks in software industry and in the limited amount of competition time contestants need to complete several software production phases - coding, testing and debugging. Currently, only coding effort is adequately graded, but grading of other activities may be improved. Ways to involve contestants in overall testing process are investigated and ways to improve solution debugging process are described. Possible scoring schemas are discussed. In International Olympiads tasks with real numbers are quite rare. Possible reasons are investigated and a way how to return such tasks back to competition arena is suggested.

Computer simulations seem to be one of the most effective ways to use computers in physics education. They encourage students to carry out the processes used in physics research: to question, predict, hypothesise, observe, interpret results etc. Their effective use requires an availability of appropriate teaching resources fitting secondary schools curricula.

Our future society will be different from that we have known in the last fifty years. Futurists foresee that in the near couple decades the world's community will traverse through a period of rapid technological innovations that will change the foundations of society as we used to know it (Tapscott, 1997; Wallace, 1999; Borgmann; 1999). Changes will engulf all aspects of life (Gleick, 1999). These changes will have great impact on society, work, culture and art. People will have to innovate or evaporate (Higgins, 1995). They will have to adapt continuously to never-ending permutations and engage in a never-ending adaptation.
