It has been proven that the development of this way of thinking in students with mental disabilities allows them to navigate quickly in the modern world, identify problems and create complex solutions. Online schooling during the COVID-19 pandemic demonstrated the possibilities of the usage of web technologies in the education of children with mental disabilities. This study aims to evaluate the impact of web technologies on the development of computational thinking of students with mental disorders. The experiment involved 14 students aged 8–12 and 4 tutors. For 8 weeks children were trained in computational thinking and computer science. Assessment of computational thinking was performed with cCT-test by El-Hamamsi et al. before and after the experiment. After conducting computer science lessons using web technolo- gies the respondents showed a higher level of computational thinking (M=15,7, SD=3,69), compared to the results of preliminary testing (M=5,93, SD=2,3). Web technologies can signifcantly increase the effectiveness of inclusive peda- gogy, which establishes the importance of integrating web technologies into the teaching system in inclusive classes of general education schools. Keywords—web technologies, web 3.0, computational thinking, online education, students with mental disabilities, errorless learning, inclusive pedagogy 1 Introduction In the age of the development of digital society and STEM grows the importance of the development of people’s computational thinking, which is aimed at the systematic solution of reality’s problems. J. Wing [48] has determined that computational think- ing (CT) is aimed at the solution of problems in the real world as a large and complex programmatic system. CT includes algorithmic thinking and parallel thinking, which involve other types of thought processes such as compositional reasoning, pattern act- ing, procedural thinking, and recursive thinking. Currently, the recognition of the need to develop CT among the younger generation is confrmed by the fact that CT is tested in PISA tests through mathematical literacy questions [26]. 74 http://www.i-jet.org
