7.2.9 Teacher Class List Methods -

n = number of students; m = report entries per student; p = parents per student. We deployed a prototype implementing Section 7.2.9 in a suburban school district. 45 teachers (grades 3–12) used the system for 8 weeks.

| Method Signature | Description | |------------------|-------------| | generateReport(ClassList c, DateRange d) | Produces attendance/grade summary | | sortByPerformance(ClassList c, Comparator<Student> comp) | Orders students by grades | | filterByAttendance(ClassList c, int minPercent) | Returns students meeting attendance threshold | | exportToParentPortal(ClassList c, Set<Parent> contacts) | Securely shares data with guardians | n = number of students; m = report

function filterByAttendance(c, minPercent): filtered = new ClassList(c.courseId) for student in c.students: if student.attendanceRate * 100 >= minPercent: filtered.add(student) return filtered If minPercent < 0 or > 100 , clamp to [0,100] and log a warning. 3.2.4 exportToParentPortal(ClassList c, Set<Parent> contacts) Purpose: For each student, securely share the student’s current progress report with associated parents via the portal API. Implements the Observer pattern to avoid tight coupling. Johnson, and J
