There is a view that primary schools pay more attention to the formal learning. Personally, I completely disagree with this view, since education system is developed relying on standarts. Including games into the lessons is also essential, because they make the lessons more interactive.
Nowadays, a number of videos and articles that encourage teachers to include more games into their lessons can be observed. They talk about interactive methods, types of games, and methods to catch the attention of the students. After watching and consuming this kind of media, teachers are more likely to implement these methods. Additionally, teachers are trained every year, and during their training they are usually tought about different teaching methods and the ways of increasing quality of lessons. It also seems logical that students are more stisfied from the lesson, in which games are included.
In the modern world, when children are obsessed with computer and mobile phone games, including games into the teaching is more than just important. The aim of every teacher is to share the knowledge, but it is not possible when students are not paying attention. In this case, games can be a solution to this problem. Children love competing and working in a team. That is why, when tasks are given in a game format, children are asked to work in pairs or in a team, scores or small prizes are given for each correct answer, children will be engaged and willing to participate in a lesson.
In conclusion, fomal education is not common in the modern education system and games play a crucial role in the effectiveness of the lessons.
