Significant changes are taking place in the modern post-industrial world both in the technological sphere and society. These changes require a review of the professional skills of future engineers. Such skills as critical thinking, well-developed communicative skills, creative approach for solving professional problems, ability of self-solving production issues and carrying out interdisciplinary research have become significant ones. The article analyzes the process of forming professional skills of future engineers to meet the requirements of the modern society. Due to our working experience, creativity and critical thinking are quite difficult to form within the framework of teaching/learning one or more engineering disciplines. However, it can be facilitated by a closer interaction of the humanitarian and engineering disciplines in the tertiary educational environment. The blended teaching approach is proposed for integrating a foreign language and engineering study. The foreign language contribution for stimulating critical thinking skills and maintaining learning motivation is a crucial thing to provide future engineers’ training which requires detailed consideration. The purpose of this article is to analyze the methodological approach for integrating a foreign language acquisition and engineering disciplines aimed at stimulating students critical thinking skills and maintaining motivation for learning. The article highlights the importance of integrating the English language into a technical university curriculum based on the principle of problematicity and verbalization of learning, using reflection exercises (reflection in action) and professional vocabulary acquisition. The authors present the results of professional vocabulary acquisition by students during the implementation of an integrative course within one semester for international student competition training in the theory of mechanisms and machines.
