Students are under the misconception that the tan x function corresponds (on the unit circle) to the line x =
1 whenever the angle is in the first and fourth quadrants and to the line x = -1 whenever the angle is in the second
and third quadrants. However, only 18% of the students in the experimental group were prone to this
misunderstanding.
All in all, the 5E model was proven to be more efficient than traditional learning methods in the minimization
of the misconceptions that arise in students either as a result of their preconceptions or during their trigonometry
education. While an average of 19.5% of the students in the experimental group persist in their misconceptions, it
is seen that an average of 53.4% of the students do so in the control group.
In Table 4, the results for the ANCOVA test may be found (which was carried out in order to ascertain
whether there was any statistically significant difference in the Trigonometry Misconception Test scores of the
students in the experimental and control groups).
