Enhancing research skills of schoolchildren through 3D modeling

The problem and the aim of the study. 3D modeling and prototyping are important areas of digital education and have undoubted didactic potential for the development of engineering thinking, which is in demand in the modern economy. The authors suggest using 3D modeling technology to develop the research skills of schoolchildren when studying natural sciences and implementing interdisciplinary projects aimed at forming the foundations of a holistic scientific picture of the world through understanding the relationship and interdependence of the natural sciences. Research methods. The work uses the following classification of research skills: operational, communication, organizational, and information. For them, the authors have identified the corresponding indicators: conducting observations and research during modeling; putting forward a hypothesis; planning research activities; and analysis of information sources. The experimental base for the study was the Vyatka Technical Lyceum (Russian Federation). During the diagnostics, the products of students' educational activities were assessed - computer models and objects printed on a 3D printer. For statistical processing of data, the χ2 -Pearson criterion was used. Results. The curriculum and lesson planning for the “Technology” course are presented, which allows students to develop research skills during the implementation of applied educational tasks. A system of tasks and sample models has been developed to support all stages of students’ research activities during the implementation of educational interdisciplinary projects following the proposed lesson planning of the module. Statistically significant differences were determined in the qualitative changes that occurred in the level of research skills of schoolchildren (χ2 =6.184; p<0.05). In conclusion, the didactic potential of computer 3D modeling and prototyping for the development of research skills of schoolchildren is formulated: putting forward a hypothesis of a natural science nature and testing it experimentally; mastering the methodology of independent planning and conducting an experiment in compliance with safety regulations, etc.
