Teaching mathematics online at the first year of grammar school

The diploma thesis deals with equations introducing at 8-year gymnasium in the framework of teaching online. This thesis is focused on an action survey in a context of teaching online in prima of 8-year gymnasium. This is a series of lessons focused on equations which were taught at Gymnázium OPEN GATE. The aim of the thesis is to follow the shift in a didactic area in a non-standard form of teaching. The diploma thesis is based on the theoretical background, the practical part is focused on a teaching experiment. For reaching the aim, the following tasks were established: -To discuss possible forms of teaching online. -To summarise the theory of linear equations. -To analyse textbooks for both primary school and lower-secondary school first from the viewpoint of a preparatory stage of equations and then the propaedeutics of equations in the framework of lower-secondary school. - To record the surveyed events connected by reflection. The thesis is divided into two main parts, theoretical and practical. The theoretical part is divided into four chapters. The practical part follows the theoretical one; it is based on analyses a priori of continued reflection. The description of scripts implementation is accompanied by a continued reflection and a posterior reflection. The conclusion provides the key..
