The subject of this thesis is the study of the birth of algebraic thinking, as a generalization process, in 10 to 14 years old pupils. We analyse the relationships between the ways of describing a general algorithm, the strategies applied in solving arithmetical-algebraic problems and verbal and symbolic languages. As a result of the study, we can confirm that the causes of some difficulties in learning elementary algebra are due to a didactic obstacle rather than to an ontogenic obstacle. Furthermore, we have found some features of didactical activity in classroom that can further or prevent generalization processes.

Abstract
The subject of this thesis is the study of the birth of algebraic thinking, as a generalization process, in 10 to 14 years old pupils. We analyse the relationships between the ways of describing a general algorithm, the strategies applied in solving arithmetical-algebraic problems and verbal and symbolic languages. As a result of the study, we can confirm that the causes of some difficulties in learning elementary algebra are due to a didactic obstacle rather than to an ontogenic obstacle. Furthermore, we have found some features of didactical activity in classroom that can further or prevent generalization processes.
