  - 'Mathematics textbooks used to be the key resource for students’ self-regulated
    learning of mathematics. Primarily due to the digitalization of society, students
    have potentially greater access to a wider range of resources such as internet
    search engines, learning platforms, educational videos, and Generative AI. This
    study investigates the role of the mathematics textbook in comparison to other
    resources within students’ self-regulated learning practices. Data were collected
    via a survey of 1101 German secondary students, representing three school types
    (Gymnasium, Gesamtschule, Realschule) and three grade levels (6, 9, and upper
    secondary). The questionnaire assessed the frequency of resource use in and outside
    class, reasons and purposes of use, and resource-based strategies when facing
    learning challenges outside class. Results show that the printed mathematics textbook
    is the most frequently used resource both in class and outside class. The textbook
    remains the most relevant resource for key purposes, such as an aid for doing
    homework and preparing for tests and exams. However, its dominance diminishes
    with age: in upper secondary school, students increasingly rely on self-created
    notes, and online resources. Correlation analyses reveal moderate to strong links
    between in-class and out-of-class use, suggesting an association between resource
    use and classroom culture. The findings underscore the textbook’s enduring centrality
    as a foundational, trusted resource within a dynamic and increasingly diverse
    learning environment. This study calls for pedagogical approaches that integrate
    textbooks more intentionally within broader resource systems, supporting students’
    agency and strategic resource selection in an era of digital abundance.@eng'
