In this study we introduce a new model for primary education called ISMS: Improving Student Motivation and Self-esteem. Following a two-year study undertaken in a primary school (n = 67), the new model was found to be successful. Students who participated in the research, reported that a course based on ISMS principles was very helpful for strengthening their perceived ability and their motivation to make an effort. They became more enthusiastic, responsible, self-confident, optimistic and determined to succeed. The meaning of such findings is that it is possible to improve key variables having vital influence on student learning and academic performance. The ISMS model was found to be applicable to primary education, in particular, but it may be suitable to secondary schools as well.
