The creation of a flexible and stimulating educational setting in which the student has freedom of choice in the activity is a fundamental pedagogical condition in the process of stimulating motivation for discovery learning. The importance of the pedagogical conditions in modern education derives from the principle of ensuring relevant education, on the basis of which education responds to the needs of personal development and allows the teacher to personalize activities according to the individual learning pace and cognitive interests of the learner. The theoretical foundations that support the pedagogical condition regarding freedom of choice in activity are reflected in theories with reference to satisfying the need for autonomy (self-determination theory: Carver and Sheiner, 1981, Deci & Ryan, 1985, Bandura, 1986); initiating one's own exploration (experiential learning theory: David Kolb, 1984), choosing one's own path of learning (pedagogical constructivism theory: Piaget, 1965, Bruner, 1970), complemented by Vygotsky with the idea that learning is efficient in the zone of proximal development, and freedom of choice allows adaptation to this optimal level, 1978). The design of the application of the pedagogical condition on providing freedom of choice in the activity will create the developmental framework, where the learner will associate with the space for personal initiative in activities of exploration and investigation.
