Moreover, studies suggest that while children in different cultures may share some common intuitive and synthetic mental models of the day and night cycle, they also have some unique models (Diakidoy, Vosniadou & Hawks, 1997;Samarapungavan, Vosniadou & Brewer, 1996).Similarly, compared with their peers in different cultures, young Turkish children might have similar and/or unique conceptions of the day and night cycle. Therefore, studies documenting thecontent of the young Turkish children’s minds are required because it has profound implications for curriculum planning and the design of pedagogical techniques appropriate for young children.
