Teaching algebraic expressions using algebra tiles
Kuchaříková, Gabriela ; Vondrová, Naďa (advisor) ; Novotná, Jarmila (referee)
The primary goal of this thesis is to prepare and carry out an education programme on algebraic expressions with variables for eight grade primary school students. This is so they can understand the basic principles of operations with simple algebraic expressions. The secondary goal was to determine whether this education method can also be applied in an online environment, which became a necessity during the Covid-19 pandemic. The theoretical chapter of the thesis covers the introduction of the symbolic language of algebra and the ways of understanding a letter (variable). It contains the definition of basic algebraic terminology in a primary school environment as well as an analysis of select textbooks. Additionally, student work levels with algebraic expressions and a categorization of students' mistakes in operations are used as supplementary grounds for the experimental chapter of the thesis. Finally, the two types of algebra tiles are presented. The experimental chapter of the thesis is aimed at the propaedeutics of algebra tiles via operations with integers, at teaching variable expressions using algebra tiles and at expanding the method of teaching expressions in primary school (Vieta's formulas, completing the square). This chapter's sections cover the respective expression operations and...
