Abstract
The growing diversity of primary school classrooms increases the need for differentiated instruction (DI) as a central teaching approach. Although DI tools, such as technology integration, gamification, and flexible classroom setups, hold significant potential to enhance learning outcomes, their practical application often poses challenges for teachers. This study investigates the perceptions of primary school teachers regarding the adaptability, challenges, and effectiveness of DI tools in diverse classroom settings. Guided by a quantitative-qualitative approach, this study examines how teaching experience, subject area, and resource availability influence the successful implementation of DI strategies. Regression analysis confirmed that market dynamics significantly affected sales performance (? = 0.492, t = 4.862, p < .001), while mediation analysis demonstrated that demand forecasting significantly mediated the relationship between market dynamics and sales performance (F = 3.986; F = 4.464; p < .001). Based on these findings, this study proposed a Data-Driven Market Responsiveness and Sales Optimization Framework integrating market dynamics as input, demand forecasting as the mediating process, and sales performance as output within a continuous feedback system. The framework underscored the importance of using predictive analytics, trend monitoring, and customer data management to transform market volatility into actionable business intelligence. This study contributed to the broader discourse on differentiated instruction by offering actionable recommendations for professional development and policy design. By identifying effective strategies and addressing practical challenges, this research supported more inclusive, adaptable, and sustainable instructional practices in primary education.
