The major aim of the research is to reveal peculiarities of strengthening delinquent 9th–10th-formers’ learning motivation in technology classes. The research objectives are as follows: to explore delinquent 9th–10th-formers’ characteristics; to analyze the peculiarities of delinquent teenagers’ learning / teaching in technology classes. The sample of the empirical research was 120 of 9th–10th-formers with behavioural and learning difficulties from schools of Vilnius and Kaunas cities and districts. 53 teachers of technologies also took part in the survey.
