En “1 Crear Examen” se explica como crear un cuestionario Moddle (Aula Virtual en la Universidad de Valencia) con opciones para utilizarlo como un “examen” de elecciĂłn mĂşltiple. En este segundo video “ 2 Crear items” vamos a ver como crear y añadir los items al cuestionario previamente creado y como añadirles puntuaciones para cada opciĂłn y feedback. El esquema de puntuaciĂłn sigue una fĂłrmula comĂşn para la correcciĂłn de la respuesta al azar basada en penalizar las respuestas incorrectas. Hay otros muchos formatos de items (por ejemplo preguntas de desarrollo) que puedes crear fácilmente tambiĂ©n basado en este ejemplo. Fácilmente adaptable para diferentes fines didácticos y de evaluaciĂłn presencial o no presencial cambiando las opciones mostradas en "1. Crear Cuestionario". In a previous video (1 Crear Examen), we saw how to create a quiz using moddle and some nice options for a multiple-choice exam. In this second video, we show how to create and add items to the quiz, particularly multiple-choice and true-false items. The video also shows how to score them by applying a common correction-Âfor-guessing formula that reduces the scores of examinees who attempt to guess the correct answer.
