Aşama 1

Preliminary Test

A standard word recognition test covering 80 target words was applied to 400 students.

Aşama 2

8 Week Application

The experimental group (200 students) learned with WordMatik, the control group (200 students) with traditional list work.

Aşama 3

Final Test

The same 80-word test was reapplied. Additionally, a delayed recall test was conducted after 4 weeks.

Aşama 4

Results

The experimental group scored 73% higher on the final test. The difference rose to 81% in the delayed test.

Research Results

  • The experimental group scored 73% higher than the control group on the final test.
  • The difference rose to 81% in the 4-week delayed test — proving long-term learning.
  • Daily active usage time increased 4 times compared to traditional word practice.
  • 89% of students in the experimental group wanted to continue using the app.
