The research examined the effectiveness of the Frayer Model Plus in developing secondary stage students' translation skills. Research participants were 50 first year secondary stage students randomly selected and equally assigned to a control group and an experimental one. Both groups were pretested and post tested on the Translation Test, developed by the researcher. The experimental group received the suggested translation program based on the Frayer Model Plus, while the control group were taught the same translation texts traditionally. Both groups received 18 translation sessions. Findings of the data analysis revealed that the value of the Independent-Samples “t" test for the overall translation skills was (16.46), and the experimental group exceeded the control one on the post administration of the Translation Test. The research results also showed the effectiveness of the suggested program based on the Frayer Model Plus in developing the participants' translation skills due to the huge of effect size value for the suggested program (d=5.63).
