How to provide students with blended human/computer-automated feedback on their speaking using a dictation with speech recognition assignment screencast

2013/05/08 Leave a comment
  1. Teachers often feel there is never enough time for grading students’  speaking proficiency. Fortunately, we can now automate feedback on pronunciation using Windows 7 dictation with speech recognition.
  2. This feature will be  available for 7 languages on Windows 7 in the LRC, here is a demo for a reading exercise dictating German.
  3. An assignment step-by-step could look like this: Students
    1. record a screencast of their dictation,
    2. read a text to the computer in MS-Word,
    3. turn track changes on in MS-Word and correct the text (immediately or after dictation) where the computer could not recognize their speech,
    4. upload their screencast to Kaltura in Moodle.
    5. To grade the performance, the teacher has to review only at the very end of the screencast to see how many corrections the student needed to make (when it doubtabout the speech recognition validiiy, the teacher can easily jump to the screencast segment in question and, if necessary, override the speech recognition).
  4. This could be a regular assignment type since it provides the following benefits:
    1. immediate automated intelligent feedback for the student
    2. little grading overhead for the teacher, so that the teacher can concentrate her work on providing aural feedback on student recorded speech as a highlight maybe twice per term, maybe after mock exams  before a midterm and final exam
    3. some multimedia pieces demonstrating language proficiency for the student’s ePortfolio.
  5. Requirements:
    1. a quality headset (we use Sanako SLH-07Sanako SLH-07 USB)
    2. Windows 7  Enterprise/Ultimate with Language Packs,
    3. knowing how to switch the display language, (optional/recommended:) TBA:a simplified language switching facility,
    4. individual voice training data: speech recognition users have to train the computer  – once, even in a deepfrozen computer enviroinment,  since we enabled you to save this data to and restore it from a flash drive or personal network share space,
    5. a reading text (often authentic texts can be taken straight from the textbook, to fit in with the syllabus, like in this example from Treffpunkt-Deutsch 1st-year German),
    6. MS-Word with track changes
    7. screencast software (we use MS community clips)
    8. a way to submit the results to the teacher (we use Moodle with Kaltura video uploading (example for teachers, students do it similarly), but email could be sufficient depending on screencast length and attachment size allowance).

How a teacher can organize a student-controlled high-stakes assessment recording session using the Sanako in the LRC

2013/03/12 Leave a comment
  1. How:
    1. An initial central microphone and speaker test (animated step-by-step) is recommended. Clear the session afterwards.
    2. Recording: Have the student operate the Sanako recorder to individually record (like during a self-access assignment)
      1. For starters, teacher can display this narrated individual recordings with the Sanako Student Recorder training screencast, it auto-starts and auto-cycles):
      2. And/or explain:
        1. Red Record Button to record;
        2. Blue Stop button to stop recording
        3. Green Play Button to play their assignment for review (also use the recap button to jump back)
        4. Menu: “File / New”, if they want to redo the assignment.
        5. Button: call/envelope to call the teacher on the teacher station for help (an audio connection between student and teacher should pause  the recorder automatically)
    3. Submitting:
      1. Individually by students:
        1. Menu “File” / “Save” (opt to save as student track mp3), to save locally, once student is happy to submit.
        2. (recommended:) upload the save file to a Moodle single-file upload assignment. Requires the teacher to create a Moodle Single file upload assignment, with optional attached file first.
      2. From the Sanako tutor at the teacher station:
        1. For entire class (If you do not need the flexibility to have students end at different times). TBA
        2. Group-wise (varying (staggered) recording times):  TBA
  2. Pro’s:
    1. Less distraction from language learning by having to operate technology (editing audio rather then practicing L2) and more language-learning-specific features (sidetone, recap) than if using Audacity.
    2. Works with the Sanako Study 1200 teacher stations (e.g. automatic pause of recorder when remote connecting to student during monitoring of recording task).
  3. Con’s:
    1. noise interference with dozens of student speaking in a confined space simultaneously. Nobody wants to return to the language lab station of yore, i.e. in a cubicle. However, a teacher-controlled oral exam (sample video, step-by-step video),
      1. can play a soothing background sound to students over the headphones which insulates them from their neighbors (prevents both distraction and cheating);
      2. there is no room  for distracting unrelated chit-chat;
      3. there is no need for distracting conversation when  students do technical troubleshooting, during highly structured question/response exams.
    2. More user flexibility/control  is achieved by more individual distracting operation of computer technology, which always implies more opportunity for user error. To reduce (not eliminate!) the error ratio:
      1. Students
        1. have to have received the general digital audio lab introduction for students.
        2. have to double-check their recordings for quality before submitting.
      2. Teachers
        1. have to monitor students’ recording progress closely
          1. which the Sanako Study 1200 teacher station (link cannot replace hands-on training) greatly facilitates (provided Students use  the Sanako Student Recorder, as described above).
          2. however, even with a classroom management system like Sanako Study 1200, it is impossible to completely monitor a class size of students operating computers. Therefore teachers
        2. have to check the validity of submissions before students leave.
          1. If you use submission through Moodle, here are 2 tips how to do this quicker:
            1. how to quickly download their Moodle file submissions
          2. Whether you use submission through Moodle or collection through Sanako tutor:
            1. view end of this video for how to quickly check validity of all file submissions in a folder using Audacity
          3. are advised to have a make-up assessment plan not only for those students missing the exam, but also for those that miss to complete the computerized multimedia assessment correctly.

How a teacher can adapt a Sanako teacher-controlled class recording activity for individual student recordings

2013/03/12 Leave a comment
  1. Pedagogical need:
    1. A teacher wants her students to record a presentation,
    2. but allow the students to move around freely in their recording afterwards, when evaluating it, and submit the best out of 3 tries:
  2. Technical implementation:
    1. Using Sanako activity:model imitation of differing for multiple groups
      1. offers maximum control, least flexibility: students have to speak their presentation linearly
      2. if you anticipate presentations of considerably different lengths
        1. first try asking your students – might be useful to them anyway to realize if theirs turns out to be much shorter than others,
        2. if students are unsure about the length of their presentation,
          1. conduct the first recording with the entire class and
          2. have students note what time their recorder time counter is at when they finish, and send you the time as text via the button:envelope
          3. group your students (grouping step-by-step) into Sessions A-F by incrementing  time according to what the student icon bubble shows
        3. then differentiate class into as many groups as necessary (if <= the 6 “sessions”A-F  Sanako Study 1200 offers) end the recording at a different time for each group
      3. for each group (one or more up to 6),
        1. choose from dropdown activity:  model imitation recording
          1. and from dropdown: source: none) with more than one group at a time,
          2. and (optionally) for not more than one group at a time (suggest choosing the biggest group for that) from (dropdown: source: file )  the  background noise to play
        2. and after each group’s allocated time (+ buffer) is up,
        3. press button:end to end the recording
        4. after collection of the recordings from students is finished, you can
        5. press button:replay image, to let each student listen to her recording (linearly, without control), and
        6. press button:free image, to let  students freely move back and forth on the timeline)
        7. eventually, press button: clear, to be ready:
      4. for tries 2 and 3: repeat above steps.
    2. using Sanako activity: self access:
      1. provides
        1. the teacher some  control (none over this turning into more of an editing than coherent language practice exercise),
        2. and students more flexibility (hence requiring prior recording training for students);
      2. students individually
        1. record
        2. move around freely in the file
        3. replay
        4. record over prior footage and/or start completely over  (menu: File / new)
        5. press button:envelope to text message the teacher that they are finished and want their (final )  recording to be collected by the teacher
      3. teacher
        1. moves signaling students into a group  (grouping step-by-step) that is
          1. dedicated for collecting recordings (TBA:does this not empty their buffer?)
          2. and button:pc control: locked (= no further or accidental changes)
        2. once an appropriate  (compromise between finished students wanting to leave and teacher not having to collect each recording individually) number of students have been added to this group, presses
          1. button: end to collect and
          2. button: clear session to clear the button
        3. assesses the recordings in the folder that opens with audacity;
          1. in case of problems, moves students  back to the group dedicated to recording
          2. else lets students leave

How teachers find their Sanako files – once they are in the right network share folder

2013/03/11 Leave a comment
  1. The beginning of the folder name with your recordings corresponds to the date/ time the exam was collected (some translation required – the date time appears in this special format yyyy-MM-dd  hh_mm) so that the folders can also be easily sorted by name, see below).
  2. image
  3. When viewing the folder, click on the column headers to sort by name (sorting by date also often works): image
  4. If you forgot when you held your exam: The exam appointment is not only in the LRC room calendar (which can get busy and takes some prior setup to be searchable), but in your own NINERMAIL calendar, so that you can check there also: clip_image003
  5. We recommend that the exams (unlike the system tests (“nametests”)  which can be collected using the computer name as filename) be collected using the student username as recording filename, you can also search the student folder for students with your username: clip_image004
  6. We also recommend that you add a memorable (to you) tag to the folder name when collecting (in this case “level2 speaking exam1”) to make it easier for you to retrieve your assessments. The best tags in this world of computers helping us find things seem to be long unique strings (think of twitter hashtags).
