Abstract
We develop the detailed application of the computer technology on testing the student's level of knowledge. We implemented a Java original code, client–server technology based on the natural process of evaluation where the college students (clients) are tested for an examiner (server). Later, we discuss the security measures implemented by leading suppliers of e–learning tools, and we distinguish an important opportunity area on the use of advanced security measures that we used to differentiate our tool. Then, we present a data mining methodology to analyze activities of students in online assessments to detect any suspicious behavior (cheating), and show the results of applying it on a real class. Finally, we propose an affordable biometric technology to recognize remote students in online assessments to solve the well–known problem of: "who's there".
Keywords: Online Aassessment System, Data Mining, Advanced Security, Biometry.
Resumen
]]> Desarrollamos una aplicación de la tecnología computational en la evaluación del conocimiento de los estudiantes. Implementamos una tecnología cliente–servidor, de código original en Java, basada en el proceso natural de evaluación donde los estudiantes (clientes) universitarios son evaluados por un examinador (servidor). Mas adelante, discutimos las medidas de seguridad implementadas por los proveedores líderes en herramientas de e–aprendizaje, y distinguimos una importante área de oportunidad en el uso de medidas de seguridad avanzada que usamos para diferenciar a nuestra herramienta. Entonces, presentamos una metodología de minería de datos para analizar las actividades de los estudiantes en evaluaciones en línea para detectar cualquier comportamiento sospechoso (trampas), y mostramos los resultados obtenidos de aplicarla en una clase real. Finalmente, proponemos una tecnología biométrica asequible para identificar a los estudiantes remotos en evaluaciones en línea para solucionar el bien conocido problema de: "¿quién está ahí?".Palabras clave: Sistema de Evaluación en Línea, Minería de Datos, Seguridad Avanzada, Biometría.
