Technological advancements are considered a vibrant phenomenon in our current era, particularly in the field of Arabic language education. One component of education that adopts this modern technology is the assessment of learning outcomes, which serves as a tool to improve the educational process and enhance the achievement of educational objectives. In Dar Al-Najah Islamic School, the teaching of morphology (صرف) suffers from a lack of attention, necessitating the integration of technological innovations to facilitate the assessment process and increase student understanding. Based on the needs analysis at Dar Al-Najah Islamic Institute, testing tools for teaching morphology based on the Android system have been developed. This development includes the design of the "Kuis Shorof" application, which features various types of questions, such as multiple-choice, true or false, matching, and word formation. Analysis results indicate that the proposed product is characterized by validity and reliability, achieving a validity score of 0.67 and a reliability score of 0.72, indicating the effectiveness of the designed questions. The product was implemented with third-grade students, where the trials showed an improvement in learning outcomes, with a 13% increase in final exam scores. Statistical analyses confirmed the effectiveness of using the product in improving time efficiency, reflecting its positive impact on the quality of education in the field of morphology. Observations also revealed the advantages and disadvantages of the developed product, highlighting the need for further improvements in the future.
