The TEI uses a two-partial grading system. Teachers can enter or update grades for each student in their assigned group from a single DataTables-powered list. The final average is calculated automatically by the updateGrade servlet on every submission and stored directly in the report table — no manual calculation is required.

​
Estructura de calificaciones

Each student has exactly one report record, represented by the Report model class (model.Tables.Report). The table has four columns:
CampoTipoDescripción
id_reportINT (PK)Identificador del registro
first_partial_reportDOUBLECalificación del 1er parcial (0–10)
second_partial_reportDOUBLECalificación del 2do parcial (0–10)
avg_reportDOUBLEPromedio final calculado automáticamente
New students are created with all three grade values initialized to 0.0.

Registrar calificaciones

1

Navegar a la sección de Información del grupo

From the teacher lateral menu, click Información del grupo. This navigates to /view/calificaciones/asignarCalificaciones.jsp.
2

Cargar la lista de alumnos

The JSP reads the gruposId session attribute (set at login) and calls base.obtenerCalificacionesPorGrupo(Integer.parseInt(id_teacher)) to retrieve all students in the teacher’s assigned group. Each row shows apellido paterno, apellido materno, nombre(s), primer parcial, segundo parcial, and promedio.
3

Acceder al formulario de calificaciones de un alumno

Click the graduation-cap icon () next to any student. This opens /view/calificaciones/vistaCalificaciones.jsp?idGrade={id_report}, where the teacher can edit the two partial grades.
4

Ingresar las calificaciones

Enter the Primer Parcial (firstPartial) and Segundo Parcial (secondPartial) values in the numeric input fields. Both accept decimal steps of 0.1 with a max of 10. The current saved values are pre-filled.
5

Enviar el formulario

Click Actualizar Calificaciones. A SweetAlert confirmation dialog appears first. On confirmation, the form submits POST /tallerDeInglesUAEM/updateGrade. The servlet:
  • Reads idGrade (int), firstPartial (double), and secondPartial (double) from the request
  • Calculates the average: (firstPartial + secondPartial) / 2
  • Builds a Report object and calls bd.actualizarReporteCalificaciones(calificaciones) to update the row
  • Sets a success message in the session (actualizacionCompleta)
  • Redirects the teacher back to /view/calificaciones/asignarCalificaciones.jsp

​
Ver calificaciones del grupo

The grade view at /view/calificaciones/vistaCalificaciones.jsp is accessible to teachers, students, and administrators. When accessed by a teacher, it shows the individual student’s current grade record in an editable form. The page also displays:
  • Ciclo Escolar — derived from the current year and semester period via base.obtenerPeriodo(mesActual)
  • Grupo — the student’s assigned group label
  • Profesor Asignado — the teacher’s full name
  • Primer Parcial / Segundo Parcial / Promedio — the three report fields (color-coded red/green for students; editable inputs for teachers and admins)
The DataTables library (Bootstrap 5 theme, Spanish locale) is applied to the historical grades table on this page.

​
Actualizar calificaciones

Grades can be updated any number of times. Each submission to POST /updateGrade completely overwrites the existing first_partial_report, second_partial_report, and avg_report values in the report table for that student. This makes grade corrections straightforward — simply re-enter the corrected values and submit again. The redirect destination after a successful update depends on the caller’s role:
RolRedirección
PROFESOR/view/calificaciones/asignarCalificaciones.jsp
ADMINISTRADOR/view/listas/listaAlumnos.jsp

​
Parámetros del servlet

POST /tallerDeInglesUAEM/updateGrade
Parameters:
  idGrade        (int)    — id_report del alumno a actualizar
  firstPartial   (double) — calificación del 1er parcial
  secondPartial  (double) — calificación del 2do parcial
  nombreCompleto (String) — nombre completo (usado en el mensaje de éxito)
The servlet is declared with @WebServlet(name = "updateGrade", urlPatterns = {"/updateGrade"}) and handles both GET and POST via the same processRequest method. The full context-relative URL is /tallerDeInglesUAEM/updateGrade as defined in Constantes.Servlets.SERVLET_ACTUALIZAR_CALIFICACIONES.
Grades are entered as decimal numbers (e.g., 8.5 or 9). The HTML inputs enforce min="0" and max="10" at the browser level, but the servlet does not enforce a server-side maximum. Administrators should inform teachers of the scale (typically 0–10) to ensure consistent grading.
