Δραστηριότητα Επεξεργασίας Εικόνας Pixlr

Pixlr is a powerful online flash-based image editor that can be included as a LAMS activity. The editor has powerful image creation and editing features, and the interface will be familiar to anyone who has used Paint, or more advanced editors like Photoshop or GIMP.

Ernie has created a demo sequence on the LAMS Community showing a Pixlr activity. (You will need an account to preview the sequence)

This animation demonstrates Authoring and Learning with a Pixlr activity.
 

Pixlr Activity Learner's Guide

The first screen displayed in the Pixlr activity shows the image uploaded to the sequence for Learners to edit.
Learners click on Edit Image in Pixlr to open the image for editing.
The Pixlr window will open, and the site will automatically fetch the image from LAMS.
Learners can make all sorts of changes to the image using the Pixlr tools.
Pixlr Help Guide
Click here to read the Pixlr manual, which describes all the tools and effects available.
Once Learners have made their changes, they can click Save to send the modified image back to LAMS, or save a copy to their local hard drive.
Back in LAMS, the activity displays a thumbnail of the modified image.
Learners can submit this image, open the image in Pixlr again for further editing, or view the submissions from other learners.
Learners can preview responses from other Learners.
(Where the Pixlr activity is part of a group or branch, only the images from learners on the same group or branch will be displayed.)

Συγγραφή με το Pixlr

The basic use case for the Pixlr activity is that the author uploads an image to LAMS which Learners can then modify. When the learners have completed their modified image in Pixlr, they return to LAMS and their image is saved as part of their sequence (the image is also downloaded with the lesson portfolio.) The image can also be made viewable by other learners in the sequence.

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 Authoring


View of the Basic properties sheet for Pixlr. Click to view full size.

The Basic Tab for the Pixlr Activity allows authors to specify a title for the activity, and give learners a set of instructions for completing the activity. The default image is also uploaded to LAMS from this properties page.

  • 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.
  • Instructions: 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 Features - Add Image: The Add Image box allows the sequence author to upload an image for learners to edit.

Advanced Authoring


View of the Advanced properties sheet for Pixlr. Click to view full size.

  • Lock When Finished: This option is available on all Activities.
    • Enabling this option in Pixlr means that once a Learner clicks "Finish" on the activity, they will not be able to make further changes to the image. The learner can still return to view the images by selecting the activity from the progress bar.
  • Allow Learners to view other learners images: When enabled, this option will display the modified images from each learner as part of the activity. Each learner will be able to see the images from other learners in the sequence or group.
  • 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).

Summary Tab


Monitoring Summary tab for Pixlr.
Click to expand.

The Pixlr Summary tab will display the Number of Learners who have attempted the activity (where necessary, shown in groups or branches) and a thumbnail of the modified image each Learner has created.

Monitors can click the thumbnail to display the full size image.

Sequence monitors can select Hide image from other learners to restrict viewing of individual learner submissions.

Instructions

Monitoring Instructions tab.
Click to expand.

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

These comments and files can be viewed from here - the Instructions Tab.

Edit Activity

Clicking the Edit Activity button opens a new screen identical to the _'Basic'_tab in the authoring environment.
From here, Sequence monitors can change the default image for the activity, and modify the activity title and instructions.

Note: if a Learner has accessed the activity, LAMS will display a warning:

Warning: One of more students have accessed this activity. Changing this content will result in students getting different information.

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 Pixlr Summary screen displays a breakdown of the number of learners who have access to the activity, and the number of learners who have completed the activity.
