The book presents the process of first and second language acquisition in children as well as
the main principles of conventional and unconventional approaches and methods implemented in
the general education as well as the language education of children. The long-term quantitative
study described focused on the comparison of the results obtained by young learners taught
English according to the Helen Doron Method in private courses and the results gained by young
learners instructed according to the modern eclectic method at public primary school. The
results were compared in such language areas and skills as vocabulary grammar language chunks
pronunciation listening skill speaking skill and a general level of language acquisition.
