Opinions and perspectives on the functioning of memory have developed and changed due to developments in many scientific disciplines. Researches and studies in this area have affected philosophy, psychology, biology and also pedagogy.
Finding out how memory works and making sure that a student remembers something is one of the key questions for teachers. Language teaching has its specificity.
We expect from students to work actively and almost immediately with the acquired knowledge, we want them to be able to use it creatively and constantly expand, build and enrich the knowledge. There are several key variables in teaching, but above all the lecturer (his personality, approach, education, methods, etc.), the student (for whom, in addition to the qualities mentioned in the lecturer, the important role plays motivation and also his mother tongue) and studying material.
If we are looking for teaching material that helps to eliminate negative interference caused by the proximity of two languages and at the same time is not directly fixed on any of the students' first/mother tongues, we can find an animated presentation combining image - sound - writing, without an intermediary language as an ideal source.
