Hola Antonio, estoy redactando preguntas en los test tipo: "rellenar hueco con la respuesta exacta". Se puede hacer seleccionando la modalidad "texto". El problema es cuando hay varios huecos en una frase, ya que no consigo que en los tests se respete el orden de mis preguntas, sino que salen aleatoriamente. Hay alguna manera de fijar el orden de las preguntas? porque en ese caso ya no tendra problema con utilizar varios huecos en la misma frase, ya que cada pregunta sera una continuacin de la primera. No se si me explico.

/*
En realidad no son cursos online sino la modalidad "plataforma" que se combina la parte online con tutoras virtuales (que tenemos que hacer externamente porque creo que no tenis una herramienta tipo videoconferencia, webinar o skype) o con sesiones presenciales. Piden siempre un 75% de asistencia en la parte online, esto es: si un curso presencial tiene 10 h, por teleformacin el alumno debe estar 7,5 usando la plataforma.
En swad he visto algo ms importante que el tiempo conectado, que son los clics, y eso es lo que de verdad demuestra que el alumno est participando y no solo tiene el programa abierto.
Si sera til poder tener los resultados de todos en bloque, porque sino tengo que entrar uno por uno y no puedo comparar, que es otra cosa que me gusta comprobar.
Por cierto, los test realizados por los alumnos solo se visualizan para los profesores si el alumno ha sealado la opcin "dejar ver al profesor", verdad?  porque no me sale ninguno.

Hola, Pilar:
Con control de asistencia en horas y minutos supongo que te refieres a asistencia online. La herramienta de control de asistencia actual sirve para pasar lista en clase presencial. Para controlar lo que ha hecho cada alumno lo que podras usar los las estadsticas de acceso, que estn en Estadsticas > Accesos > Accesos asignatura. Luego puedes seleccionar los usuarios y ver diversas estadsticas, como el listado detallado de cada estudiante, o unas grficas de acceso por fechas. Si quieres el detalle de cada alumno, efectivamente debes ir sacando un informe de uno por uno.
Esto no est programado de otra forma porque eres la primera persona que lo solicita. Ten en cuenta que la herramienta se usa principalmente para apoyo a la docencia presencial. De todas formas, apunto en la lista de sugerencia por hacer, la posibilidad de sacar un informe de accesos individualizado para cada alumno, pero sin tener que ir uno por uno.

/* TODO: Mensaje del profesor Joaqun Manuel Durn lvarez
 * Estimado Antonio:
Como todos los aos te voy a preguntar si vais a implementar una opcin, en donde yo pueda bloquear a un alumno sin necesidad de borrarlo de la asignatura. Si lo borro, pierdo todos sus datos sobre trabajos entregados y las notas que le haya puesto. Y algunas veces cuando la gente aprueba, prefiero bloquearlo pero que siga dado de alta para consultar cosas.
O incluso para gente que pierde el derecho de examen por curso y puede recuperarlo. Son mltiples situaciones distintas en las que vendra muy bien esa opcin.
Gracias por todo. Seguimos en contacto

Respuesta:
Hola, Joaqun, qu tal?

He estado discutiendo tu mensaje un buen rato con Javier Fernndez @jfernand y ms o menos entendemos que podran ser interesantes distintos tipos de roles, cada uno con diferentes permisos:

- estudiante bloqueado
   Sera parecido a un usuario que visita otra asignatura, en el sentido de que no podra ver nada que no sea pblico, ni podra editar nada, pero aparecera como estudiante bloqueado en la lista de estudiantes de la asignatura.

- estudiante antiguo / estudiante invitado
   Podra acceder a (leer) los materiales de la asignatura, pero no recibira notificaciones ni podra editar. Aparecera en las listas como estudiante invitado.

En cualquier caso el estudiante siempre podra borrarse de la asignatura, como ya ocurre con cualquiera de los roles existentes.

Anoto tu comentario y mi respuesta en la lista de mejoras por estudiar e implementar, aunque ahora mismo no puedo ponerla como la primera de la lista por haber otras con mayor prioridad y por la dificultad que supone crear un nuevo rol. Hace un tiempo cre el nuevo rol de profesor no editor y llev meses dejarlo ms o menos fino, ya que, aunque est bastante sistematizado, en la prctica supone cambiar miles de lneas de cdigo por todo el programa (que ya va por las 240 000 lneas) donde se hacen comprobaciones sobre lo que puede hacer o no cada rol.

Hablando con @jfernand se nos ocurre que para el primer caso (estudiante bloqueado) slo hay dos opciones ahora:
- Borrarlo de la asignatura (es lo que hace Javier) por ejemplo si desaparece de las actas. En este caso te sugiero que antes de borrarlo hagas dos copias de seguridad:
  1. En Archivos > Trabajos, crea un zip de todo y gurdalo en tu ordenador.
  2. En Usuarios > Estudiantes > Ver como lista > Botn superior izquierdo "Mostrar todos los datos en una tabla" > Guardar esa tabla como pgina web o (copiarla en una hoja de clculo) en tu ordenador.
- Dejarlo tal cual, como si fuera un alumno ms

Para el segundo caso (estudiantes antiguos o invitados) tienes dos opciones:
- Crear una asignatura cada ao y dejar ms o menos congeladas las asignaturas de aos anteriores. Tiene la desventaja de tener que subir todo el material cada ao.
- Crear grupos dentro de la asignatura con los estudiantes de cada curso. Seguiran recibiendo notificaciones de los cambios en la asignatura.

He guardado tu correo y esta respuesta en mi lista de "TO DO" (por hacer).
Saludos,
Antonio

/* Sugerencias de Atanasio Jos Rubio Gil (marzo de 2019):

Te escribo por aqu porque no hay notificaciones para los comentarios o posibilidad de seguir hilo. Ah van dos mejoras chulas. Las otras que se me ocurren son ver slo posts de estudiantes o mutear anuncios oficiales y hostear las imgenes en un servicio externo (como imgur, que permite subida y enlazado automtico) para que no pierdan calidad.

Muchas gracias por esta pedazo de plataforma!

Respuesta:

Pues la verdad es que notificaciones de comentarios s hay (lo puedes comprobar en Perfil > Ajustes), lo que pasa es que desde que he puesto el timeline nada ms entrar, la notificacin se marca como vista por el hecho de ver el timeline. Quiero decir, que si ests en otra opcin vers la notificacin, pero si te acabas de identificar, como lo primero que se hace es ir al timeline, se elimina la notificacin. Pensar a ver si hay alguna solucin.

Lo de la calidad de las imgenes es cuestin de aumentarla un poco al comprimirlas, aunque ocuparn ms. Lo ver.

Lo de mutear anuncios, en principio prefiero hacer una opcin para seguir masivamente a usuarios de asignaturas y que la gente use preferiblemente la opcin de ver slo los mensajes de los que sigues.

Ya voy a empezar a darte la lata... Aunque esto es algo que tengo apuntado desde hace tiempo. En los msteres es complicado hacer una plantilla de horarios como la que tienes en swad, pero nos obligan a meter el horario, con aula y profesor, por cada sesin. Por ejemplo,

https://oficinavirtual.ugr.es/awc/horario/ve_horario/visor.jsp?programa=M37156&siglas=15

contiene una de las que yo imparto. As que me imagino que te esperars la sugerencia (peticin con caf o cerveza como recompensa): sera posible que en la pestaa de horario se pudiese embeber esa pgina? (Creo que los grados usan algo parecido tambin.)

TODO: JJ: Hoy me ha saltado una "alarma" en swad cuando haba asignado un proyecto a un estudiante, pero no haba puesto que estaba asignado. No sera conveniente que si se asigna a un estudiante se ponga automticamente que est asignado?
      Respuesta: Tienes razn. La explicacin de por qu no lo hice as seguramente es que antes, en vez de "Asignado" se indicaba "Preasignado", y no cambiando automticamente a "S", los ofertados quedaban marcados como no preasignados incluso despus de que se aadiera al estudiante al que se le "postasigna". Pero ahora "Asignado" se usa tanto para los preasignados como para los "postasignados", con lo cual s sera conveniente que se activara el "S" automticamente para evitar el aviso de error (tringulo amarillo). Lo anoto y lo corrijo en cuanto pueda.

Hola Antonio:

Dado que Sergio sigue sin dar seales de vida lo he dado por perdido y estoy continuando yo el desarrollo del mdulo de Kahoot. Durante las pruebas he detectado dos problemas:

1. Al recuperar el nmero de preguntas de un juego se devuelve un valor incorrecto. Por ejemplo, en la asignatura Prueba el juego "Prueba" tiene 37 preguntas pero el servicio web devuelve un nmero muy alto:

<numQuestions>1701605202</numQuestions>

2. Desde anoche cuando creo una partida dentro de un juego y la inicio no se cargan las opciones de respuesta en la pantalla de la partida. Sale permanentemente la animacin de "Cargando". Esto ocurre en la asignatura Prueba, el juego "Prueba" y la partida "Prueba". Esta incidencia es bloqueante, ya que me impide continuar con las pruebas.

Podras revisar estas dos incidencias para poder completar el desarrollo, por favor?

Muchas gracias,.

Juan Miguel.

Sugerencia de J.L Bernier. Al eliminar los estudiantes, que se eliminen los trabajos opcionalmente marcando una casilla.
En Actividades, no permitir acceso a documentos mientras dura la actividad, tambin opcionalmente.
Que no haya dos sesiones del mismo usuario abiertas al entregar actividades, o hacer algo como en los exmenes, log.
Que al subir un fichero por defecto est oculto, aunque sea opcional.
Al subir cosas para los grupos, en documentos, resltar ms los grupos porque no son conscientes...
Exportar listas en CSV.

Sugerencia de Raymon Moreno:
Saludos cordiales estimado, tengo un planteamiento que hacerle con respecto a la actualizacin de las asignaturas que estn aperturadas en las distintas titulaciones que administramos en la Universidad, el escenario es el siguiente, tenemos asignaturas que en este momento no tendrn alumnos inscritos porque no hay secciones abiertas pero que en prximos lapsos si tendrn participantes inscritos, por lo que quiero consultar si hay manera de que se puedan como INHABILITAR TEMPORALMENTE, y cuando se requiera nuevamente la inscripcin de los estudiantes se puedan ACTIVAR o HABILITAR, creo que esa funcin de ACTIVAR la hacemos los administradores de Titulaciones cuando algn profesor crea una asignatura....... entonces algo como eso........ todo esto con el fin, de que no se pierda lo estructurado que posee cada asignatura........

El otro escenario esta orientado en lo siguiente, Si no es Factible lo de la INACTIVACIN de asignaturas quisiera intentar borrarlas y guardar el Contenido en MALETN, pero no me permite guardar los elementos que se disponen en los apartados iniciales de cada asignatura y que tienen la opcin de ser de LECTURA OBLIGATORIA por el estudiante, entonces mi consulta es, como podra almacenar estos elementos en Maletin, de manera que cuando se vaya a aperturar la asignatura nuevamente se pueda cargar tanto el contenido, como los aspectos de Gua, Informacin, Programa o Temario, Bibliografa.......

son planteamientos que facilitaran la organizacin del entorno para cada titulacin y no tener secciones inactivas que signifiquen una data no ajustada a la realidad el uso de la misma..............

siempre atento a sus comentarios y agradecido de antemano por la ayuda que siempre nos ha brindado.........Saludos Caribeos desde Venezuela

TODO: Emilce Barrera Mesa: Calificacin integrada de las actividades. No olvides por favor la opcin de calificar y asignar nota en cada actividad o trabajo. Eso agregara un toque de supereficiencia a tu plataforma.
TODO: Emilce Barrera Mesa: Para futuras mejoras podras incluir por favor la opcin de duplicar una pregunta al momento de crearlas. Esto en razn a que si tengo dos preguntas con las mismas opciones de respuesta, pero diferente enunciado me ahorraras tiempo si me permites duplicar la pregunta y solo cambiar el enunciado.
TODO: Emilce Barrera Mesa: Quiero preguntarte si es posible que me habilites la opcin de que en el examen solo tenga en cuenta las respuestas correctas para asignar la nota. Es decir que no reste puntaje por las preguntas incorrectas, que tanto incorrectas como sin contestar tengan el valor de cero.
TODO: Emilce Barrera Mesa: Podras agregar por favor una opcin que me permita exportar en excel, cvs o pdf el listado de estudiantes y la nota optenida en el examen. Eso me ayudara mucho a la hora de pegarlas en mi planilla de excel.
TODO: Emilce Barrera Mesa: Mis estudiantes presentan muchas dificultades a la hora de poner la foto porque la plataforma es muy exigente respecto al fondo de la imagen.

TODO: Al confirmar el DNI de un profesor, sale "Wrong action" en el horario de tutoras.
