The purpose of the study was to investigate 8th-grade students' development of functional thinking through a SimCalc MathWorlds integrated teaching experiment. The study sample consisted of 12 8th-grade students studying in a public school in Ankara. A teaching experiment was applied to these students, and lesson plans were prepared by integrating the SimCalc MathWorlds application. This teaching experiment consisted of a total of 11 lesson hours with 6 sessions. Observations and activity sheets were used to develop lesson plans during teaching experiments. To examine the development of the students, a Functional Thinking Test was developed, and this test was applied to the students as a pretest and posttest. Wilcoxon Signed Ranks test was used to analyze students' pretest and posttest scores. As a result of the analysis, a significant difference was found between the students' scores. In the qualitative data analysis, the student's responses in the Functional Thinking pretest and posttest were coded in terms of strategies and analyzed for each item. As a result of the analysis, the students showed an increase in the correct strategies in the questions of drawing the graph, writing the equation of two variables that are related to each other, and finding the slope of the graph and equations. Moreover, the number of students who could explain the increase in unit time as the slope and the coefficient of “x” by looking at the table, graph, and equation increased. These results suggest that seeing the tables, graphs, and equations simultaneously in the math worlds created by the students might have been effective in students' understanding of the concept of slope.
