In order to analyze the effects of students’ involvement into science classes, every group of two students obligatorily present their task product, which brought a higher class involvement for there was no one who did not participate in the presentation. As the option for selecting a study theme and a method for presenting it was given students, which makes them take the lead of the class, the level of the preference to the class was found higher. And it was allowed for them to give positive feedback to their classmates, which resulted in a positive thinking on the science class and brought an improved consequences on their involvement and preferences to the class as well.
