Independent t-test on the 5-item open-ended questionnaire: experimental mean 8.38 (SD 2.202) versus control mean 3.21 (SD 1.578), t = 7.565, p = .000, Levene's p = .269. Scoring used 0 = none at all, 1 = partially, 3 = completely.

"Participants' scores on the open-ended questionnaires and the written exam administered by the teacher revealed that the students in the experimental group have achieved a greater level of success when compared to those in the control group."
