Η δραστηριότητα Τηλεδιάσκεψη μέσω Διαδικτύου με το Dimdim παρέχει έναν απλό τρόπο να συμπεριλάβετε τηλεδιασκέψεις μέσω διαδυκτύου με το Dimdim σε μια ακολουθία του LAMS.

To Dimdim είναι μια υπηρεσία διαδικτύου που παρέχει κείμενο, whiteboard και διαμερισμό της επιφάνειας εργασίας μέσω του περιβάλλοντος του φυλομετρητή σας, το οποίο σημαίνει ότι δεν χρειάζεται να κατεβάσετε κανένα επιπλέον λογισμικό.

*Ένας χρήσιμος οδηγός για το Dimdim είναι διαθέσιμος να τον κατεβάσετε από [εδώ|http://sourceforge.net/project/showfiles.php?group_id=176809&package_id=275884&release_id=598960].*

Dimdim Authoring

Under Development
Features described on this page are currently under development.
Described specifications and features may change in the future.

All properties sheets contain three tabs:
* *Basic:* Which controls the _Content_ of the Activity.
* *Advanced:* Which controls the _Behaviour_ of the Activity.
* *Instructions:* Provides information on the structure of the activity.

Basic Tab

!ddim_basic.PNG|thumbnail! *View of the Basic tab for Dimdim Authoring.*

The Basic Tab for the Dimdim Activity allows authors to specify a title for the activity, provide a brief message to learners, and specify basic configuration settings for the Dimdim Conference.
* *Title:* All Activities have a web page title which is presented at the top of the activity page when displayed in the Learning Environment. This is _NOT_ the same title as the Title that can be set using the [Properties Inspector|authoring#propinspector].
* *Content:* All Activities have a text area that is presented beneath the title. This is where the main activity text to be displayed to learners is entered. The text can be formatted using the Rich-Text Editor. Image, Video, Audio and URL content can also be displayed in the Instructions area.
* *Specific Feature - Dimdim Settings*
** *Number of Microphones:* This specifies how many active microphones are permitted in the Conference. For example, in a simple teacher-student presentation, only one microphone would be required. For multiple speakers, additional microphones would need to be created in the conference. Dimdim Open Source can support up to three simultaneous microphones in the one conference.

The number of microphones can be changed underway by the conference leader through the settings tab in the Dimdim conference.



Advanced Tab

!ddim_advanced.PNG|thumbnail! *View of the Advanced tab for Dimdim Authoring.*

* *Add Notebook... :* This option is available on all Activities. Enabling this option creates a Notebook as part of the Activity, which Learner's can use to reflect on the activity just completed. The reflections are personal (ie: not shared with other learners).

Dimdim Monitoring

Under Development
Features described on this page are currently under development.
Described specifications and features may change in the future.

Summary Screen

!ddim_summary.PNG|thumbnail! *View of the Dimdim Monitoring Summary tab.*

The *Summary Tab* for the Dimdim Activity shows the configuration of the Dimdim conference, and provides a one-button link to begin the conference.

Starting a Dimdim Conference

A sequence monitor must begin the Dimdim conference by clicking !startConference.png! before Learners can join.

Unlike other LAMS activities, the Dimdim Conference must be started from within the monitoring environment. Learners will not be able to access the conference until a Monitor has started it.

Instructions

!lachat11monitoring^instructions.PNG|thumbnail! *View of the Dimdim Monitoring Instructions tab.*

In the Authoring Environment, Authors can use the Instructions Space to attach support files for a specific activity, or leave comments for other Monitors about how a given activity should be run.

When adding instructions to Dimdim activities, Authors may like to include supplemental information that teachers can use in an offline setting environment (eg: Blackboard points, worksheets, etc.)

Edit Activity

Clicking the *Edit Activity* button opens a new screen identical to the 'Basic' tab in the authoring environment.
* *LAMS 2.0.4* will only allow Dimdim editing if +no learners have reached the activity.+
* LAMS 2.1 allows editing the Dimdim activity at +any time+ during a sequence.

Note that using Live Edit *does not* give Authors the ability to modify the content of the Dimdim Conference - only the text that is displayed to Learners by LAMS before they enter the conference room.



Unlike [Live Edit], this form of Editing can only modify the content of an activity, as opposed to the structure of a sequence.

Statistics

The *Dimdim Summary* screen repeats the numbers of Learners who have attempted and/or completed the Activity.
