Q:Concurrent exam scheduling

Sanako has no scheduling system to allow a limited number of users to take an exam simultaneously (but it prevents users beyond the licensing seats to use the Sanako, including for exams), Scheduling plug-ins seem to be available for Moodle.

Outlook: Need more licenses for the Sanako to match the UNCC class size

Students of the Oaklawn Language Academy visited the LRC …

… and sent us a thick envelope chock-full of these very sweet handwritten thank-you notes.

I have twin nieces their age, so I know that it can take a bit to get them to write these notes (I am looking at you, Miss M…! Smile).

The little man on the screen they mention, that can talk in tongues is the Microsoft-Deskbot, and the headphones they mention were connected to a Sanako Study 1200 digital audio lab.

I hope we can upgrade all this to Windows 7 this summer, and that the Language Academy will be back next spring to admire it all…

How to combine oral cue audio with images in Sanako Study 1200 authoring-tool

  1. This 100-second authoring tool screencast shows how to
    1. preview the audio in the authoring tool,
    2. add an image and
    3. set its display time on the timeline,
      1. If you make an error by assigning non-sensible times, the authoring tool helps you by flagging it red:
      2. sanako-authoring-if-you-make-error-flagged-red1

    4. save (save frequently, on my Windows-XP SP3 machine, the image display within the authoring tool caused frequent BSODs, seemed video-driver-related).

How to use visual instead of aural cues during a Sanako oral proficiency exam

  1. This exam file has been authored with the Sanako Study 1200 TBA:authoring tool. It is displayed from  the Sanako tutor application:
    1. images on a projection screen connected to the teacher computer,
    2. aural portion through the tutor-controlled Sanako student player and headsets. 
  2. To protect the integrity and allow for reuse of the exam, only the initial instruction, example and collection of the results of an exam with visual cues are shown in this screencast.

How a teacher can use Sanako voice insert to easily add spoken comments to students’ Sanako oral proficiency exams

  1. All other things equal (given a limited amount of time), teachers can provide more and better corrective feedback on student oral proficiency recordings if, during their grading, they could easily insert their own oral comments into the students’ recordings (delivered as MP3 files to teachers’ desktops after Sanako oral exams).
  2. Both the Sanako Tutor and Student Player have a voice insert mode that is much easier and quicker to use than (albeit not free as) editing the student audio in Audacity (which we still recommend for bare-bone viewing/listening because of Audacity’s capability of loading and displaying multiple tracks simultaneously).
  3. Fortunately, Sanako tutor/student player are available on the teacher/student station PCs in the LRC (the latter’s insert function is available when the PC connected to the running Sanako Tutor on the teacher station).
  4. How easy and fast is it to use this? As you can see in this demo screencast on how to use Sanako voice insert to add spoken comments into your students’ Sanako oral exams, voice insert only requires:
    1.  a click on the voice insert button in the center, whenever a user wants to speak during listening,
    2. and, from the top left menu, a “file”/ “save as” at the end.
  5. In a next step – not only during the grading process –, how easy is it to distribute student recordings made with Sanako to students? That is TBA:a different story.
