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 elección múltiple. 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 opción y feedback. El esquema de puntuación sigue una fórmula común para la corrección 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 también basado en este ejemplo. Fácilmente adaptable para diferentes fines didácticos y de evaluación 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.
How to calculate the probability of a correct answer given a logistic model (1PL, 2PL, and 3PL) Knowing the examinee's theta score and the item parameters, this video shows how to calculate and interpret the probability of a correct answer.
This podcast explains slide 2 from the document “T13.01. Information functionsâ€. Contents: -Description and interpretation of a graph displaying the ICCs of two items. -Comparison of the two ICCs from the perspective of the item the discrimination.
Each logistic model (1PL, 2PL or 3PL) presents a definite way of Item Characteristic Curve. How to identify which logistic model to apply based on the ICC graphs? This podcast explains how to choose the logistic model based on the ICC graphs on slide 2 in the document T13.01.
10.4 Bias in Selectionâ€, slide 6 Please open the Document “T10.4 Bias in selectionâ€, slide number 6. Read it carefully, and study the graph displayed to understand how it works before to listen to this podcast. - Student’s question: On “T10.4 Bias in Selectionâ€, slide 6, in the graph, the majority group is said to give underpredicted values and the minority group is said to give overpredicted values. Is it true or is it that the majority group gives overpredicted values and the contrary for the minority group? Kind regards.
