Abstract :

The use of appropriate teaching methods for students in the classroom is a challenge. The effectiveness of teaching is determined by what methods the teacher uses when teaching. Reverse Whole Brain Model is the result of Sianipar’s thinking in his article in 2025. Sianipar states that the Whole Brain Model has the necessary things for Aphasia students (Sianipar, 2025). The research method is quantitative, using questionnaires as a measurement tool to determine the effectiveness of the Reverse Whole Brain Model. Questionnaires were created by researchers using the Theory of Effective Instruction from Slavin (1994). The data analysis technique is Aiken’s V to test the validity of experts who have assessed existing instruments. The calculated r value of all statement items has a value above 0.304. The calculation of sig. (2-Tailed) of all items has a value of 0.000, which is smaller than 0.05. All items in the questionnaire meet the requirements to be declared valid and suitable for use as a data collection tool. In terms of the validity test, it is greater than 0.60. All items have a value not far from 0.989. From the calculation of this reliability test, it can be concluded that all statement items in the questionnaire are declared reliable to be used.
