  - "Mathematical problem solving is a highly complex competence that needs\r\nto
    be supported throughout the learning process. This study examines the role of\r\nproblem-solving
    heuristics among 73 sixth-grade students in a German secondary\r\nschool (Gesamtschule).
    Specifically, we focus on the empirical relationship between\r\nthe occurrence
    of heuristics, their suitability, and application, as well as their contribution\r\nto
    problem-solving success. To this end, we developed a heuristic training that\r\nintroduced
    strategy keys (heuristic aid cards) accompanied by explanatory videos. By\r\nleveraging
    variations in the successful application of the heuristics between students\r\nand
    across multiple sessions (73 students in 4 training situations and 3 problems\r\nin
    a final test), we discover from regression models with student and task-fixed
    effects\r\nthat a successful use of heuristics (i.e., an heuristic occurred, that
    heuristic had\r\na high suitability regarding the problem, and it was applied
    correctly) leads to more\r\nsuccessful mathematical problem solving. Regarding
    the underlying mechanism, we\r\nfind that all dimensions of heuristic use (occurrence,
    suitability, and application\r\nof heuristics) are positively related to problem-solving
    success. When comparing\r\nthe predictive capacity of all three aspects, we identified
    the correct application of\r\nheuristics as particularly conducive for better
    problem-solving success. In comparing\r\nthe group of students with high to those
    with low initial math competence, we find no significant differences in the relationship
    between heuristic use and problemsolving\r\nsuccess across achievement groups.
    Our results emphasize the crucial role\r\nof heuristic application in mathematical
    problem solving, which generally benefits\r\nstudents regardless of their overall
    math competence.@eng"
