Abstract

This qualitative study examines the impact of real-life industry immersions on students’ attitudes towards mathematics and their academic choices related to the subject. It explores how these experiences, grounded in the principles of Operant Conditioning, Neuroplasticity, Behavioral Shaping, and Behavioral-Environmental Interaction, can foster positive behaviors and build a foundation for math-oriented career paths. Behavioral Shaping emphasizes the gradual reinforcement of problem-solving skills, fostering confidence and persistence in tackling mathematical challenges. Meanwhile, Behavioral-Environmental Interaction highlights the influence of dynamic learning environments on students’ engagement and attitudes toward mathematics, showcasing the importance of supportive settings in fostering interest and motivation. Through semi-structured interviews with 25 teachers from academic settings in the Philippines, the study examines the role of industry immersions in promoting hands-on learning, fostering collaboration, and contextualizing mathematical concepts in real-world applications. Findings underscore the importance of integrating industry-driven projects, leveraging environmental factors, and providing equitable access to these transformative experiences. The study concludes that industry immersions can effectively bridge the gap between theoretical instruction and practical application, ultimately shaping students’ perceptions of mathematics as a valuable tool for solving real-world problems and pursuing fulfilling careers.
