For the Bachelor's degree in engineering, field project activities are the key component of the curriculum. Incorporation of project activities facilitates an increase in the effectiveness of mastering the educational program. The Project-Based-Learning (PBL) provides a means for faster adaptation of students to future professional activities. We have discovered, that involving students in the realization of IT-technological socially-oriented projects allows high effectiveness in the realization of all four CDIO initiative provisions – Conceive, Design, Implement, Operate. It was brought to light that when realizing socially-oriented projects, if the project team consists of not only IT-developing students but also humanitarian fields' students, project activity's effectiveness and quality of the final product substantially increase. Approbation of interdisciplinary socially-oriented projects' realization was carried out. Achievable positive effects of their realization were established. The creation of the «PetSearch» system that helps find lost pets was one of the most successful projects. The effectiveness of the influence of project activities on the increase in motivation and academic performance was evaluated.
