The Question-Answer-Relationship (QAR) strategy has been suggested to improve EFL students' reading comprehension. Nonetheless, disappointing outcomes when using the QAR instruction were noted. The current study seeks to: (1) add the Review (R) component to the instruction; and (2) assess the effectiveness of the developed Question-Answer-Response-Review (QARR) instruction to improve reading comprehension among Thai EFL university students. Instructional concepts such as common question types (Yathip & Chanyoo, 2022), the Question-Answer-Relationship strategy (Raphael & Au, 2005), the experiential learning approach (Kolb, 2014), and the reading instruction principle (Raphael, Highfield, & Au, 2006) were synthesized to create the instruction. The developed curriculum was implemented with 58 Thai EFL students. Data were examined using frequency, mean, standard deviation, and F-test. As for the findings, the experts' high degree of agreement (M = 0.96) demonstrated the efficiency of the developed instruction. One-way repeated measures revealed that the posttest (M = 21.74, SD = 4.12, d = 0.89) and delayed posttest (M = 22.19, SD = 4.23, d = 0.95) were substantially higher than the pretest mean scores (M = 16.86, SD = 5.59, p <0.001) with a large effect size ([eta squared] = 0.209). Participants' satisfaction surveys strongly agreed with the created instruction (M = 4.36, SD = 0.63), consistent with interview data.
