    Create a function that analyzes a student's performance record and identifies all learning activities where the student has demonstrated sufficient mastery, based on a specified proficiency threshold. The function should take a dictionary containing learning activities and their corresponding mastery scores, along with a minimum threshold score, and return only those activities where the student's performance meets or exceeds the threshold. This filtering mechanism will help identify which learning competencies have been successfully achieved and can be used to guide further educational planning.
