Abstract:

The aim of this study is to examine the science activities in the science textbooks recommended by the Ministry of National Education for secondary schools and the activities in the science support education room activities book for gifted students in terms of reasoning with data. In this qualitative research, document analysis was carried out. A total of 47 activities, 32 activities from the textbooks and 15 activities from the support training room book, were coded in line with the determined categories. According to the findings, "data collection skill" among the reasoning with data is the most emphasized skill in the activities, but skills such as drawing and interpreting graphs based on data, identifying and interpreting the relationships in the table were included in a limited number of activities. On the other hand, the ability to consider ethical principles while presenting data by recreating a graph/model by changing variables was not included in the activities.
