Specific Ipad Apps for Phase III: Matt Tietjen

Much thanks to guest blogger, Matt Tietjen, for these specific ideas to use an iPad to support students in Phase III. Invaluable!

Goodnotes: You can take pictures of educational materials, zoom in on important details, isolate one problem or diagram at once and also write on it.  You can use the writing feature to highlight salient features, or the student can use the writing feature to complete the assignment. For example, I have a student who does best with one math problem per page rather than several.  Each morning of the week, her class gets a “morning math” worksheet with several problems on it.  The paraprofessional would use Goodnotes to take a picture of each problem on the worksheet and quickly create a digital notebook for that worksheet, with one problem per page. The student could then flip through the notebook and write on the iPad to solve one problem at a time.  Her final product could be saved in a folder on the iPad and also turned in by emailing it to the teacher or uploading it to apps like Google Drive or Dropbox.

Snaptype: Very useful for minimizing complexity in worksheets by taking a picture of a worksheet, zooming in on one problem at a time, and allow the student to type an answer for each problem using the onscreen keyboard or an adapted Bluetooth keyboard. Great for math worksheets!

Photo Album/ Camera: Yup! Just the regular old photo album and camera on the iPad. Can be used to reduce complexity and capture distance information in so many ways. Here are some ways I am using it:

  • For all those circle times/morning meetings when the teacher may only decide a few minutes ahead of time what book she is going to read, the para can get the student’s iPad and snap a picture of each page (only takes a few minutes to do an entire book). The student now has a personal copy of the book on her iPad that she (or staff) can flip through to follow along with the teacher and zoom in on any important details, masking out irrelevant surrounding information on each page.
  • Create an “album” for wall materials. Take pictures of each poster, word wall, map, etc. on the classroom wall and save them to an album on the student’s iPad. That way, when the teacher is referring to that map, word wall, etc., the student can follow along and zoom in on the pictures at her desk.

Bitsboard: Awesome for making custom flashcard activities for touching a named picture, reading bubble outlines without words in them, touching a picture from an array when its salient features are named, etc.  You can use this app to create custom picture touch games using anything you want – photographs of the child’s favorite objects, 2D image assessments, letters, numbers, words, etc. Many of my students like it a lot.

Counting Bear: Great for math. It visually marks each item as you count it. Students still have to practice systematically searching the array of items in order to count but with the support of visual markers to help them keep track of what has already been counted and what items still need to be counted.

Pictello: Fantastic for making custom made stories – either modifications of actual children’s books, experience stories or stories that the student helps write. You can include pictures, photographs, videos, etc. as part of the story and it reads the story aloud to the student. Can be great for creating school-to-home daily or weekly communication logs where the student helps take pictures of items throughout her day and then uses the app at home to communicate about her day to her family. She could also use the app with her family to create experience stories about vacations and special events to share with friends and teachers at school. For example, a student could take pictures of her weekend activities and create a story called “my weekend” that she shares with her class during morning meeting.

Voicedream app: You can use this app to read (or listen to) any pdf or word document as well as anything from Bookshare. It has a more natural reading voice than some of the other text to voice apps (in my opinion). You can adjust font style and size, and you can set the app to mask some of the text so that it only shows one line at a time, 3 lines, or 5.  It also has a yellow highlight that moves from word to word as the automated voice reads.

YouDoodle: can use it to import pictures and highlight salient features (as Christine Roman-Lantzy has taught us). I also have a student who likes using it himself to highlight salient features on photographs he has taken.

Google Images and Youtube: I use Youtube and Google images quite a bit.  If I wanted to bring distance info. (like giraffes) to a student who was about to visit the zoo, I might show him a few videos on the Youtube app about giraffes and where they live.  When there is an abstract picture in a children’s book (which is almost always) I often open up Google Images and find a real photograph version of the same thing and compare the salient features between the real photograph and the more abstract illustration in the book.

Calculators: for students high on The Range and in the upper grades, using scientific and graphing calculators can be a real challenge due to complexity of array.  It seems that calculators that incorporate color coding to reduce complexity of array may be a better choice for many kids with CVI. Here are a few promising ones:

  • Kalkulilo Scientific Calculator: uses color coding to help reduce the visual complexity of the keyboard and group keys by function.
  • Scientific Graphing Calculator (William Jockusch): Each graph on a coordinate plane is a different color and is color-coded to match the equation that goes with it. This type of color coding really helped my high school student in algebra II this year.  She had a physical TI-84 Plus calculator, not this app, but it was color coded similarly.
  • Calculator (Infinity Symbol) incpt.Mobis:  This calculator uses color to differentiate symbols from numbers and other parts of the equation. Can help reduce complexity of array.

What Do iPads Support for Students in Phase III

As discussed many, many times, the strategies for CVI must match the assessment results using the CVI Range (Roman-Lantzy 2007). We never can just randomly apply a strategy because it will not fit the functional visual needs of the child. If it does not fit the functional visual needs, it will not provide visual access and will not foster improvement of cognitive and visual skills.

With that reminder, I was asked about ideas for iPad apps for children in Phase III (Roman-Lantzy). Just providing a student with an iPad does not guarantee access. We need to assess the child, think about their visual needs and carefully use the iPad as a tool to provide that access.

What can be some general needs for students in Phase III?

Color: The student might benefit from color highlighting to draw visual attention to salient features of pictures and text. (Roman-Lantzy)

Light: Backlighting helps foster access to materials especially in 2D (pictures and text).

Latency: There is still a need for increased time for full visual exploration and full visual understanding.

Visual Field: Lower visual fields might be affected.

Visual Novelty: Presenting novel materials might requires salient feature and comparative exploration. (Roman-Lantzy)

Complexity: Complexity affects visual understanding in objects, increased arrays, of faces, and of the sensory environment.

Distance: Near information is more accessible. Distance curiosity is not typical so distance information is missed.

 

How do we want the iPad to support the student in Phase III based on assessed need?

Color:

  • Tools for color highlighting help support salient feature discussion in pictures and text.

Light:

  • Backlighting helps with understanding and easy of access to prevent fatigue.
  • Moving to 2D: taking pictures of their items in the environment and then providing the 2D on the backlighted iPad.

Latency:

  • Provides ability to capture images and videos for longer visual access time.
  • Capturing images can be reviewed as long as needed.

Visual Field:

  • iPad placement is flexible matched to child’s best visual field.

Visual Novelty:

  • Expanded understanding: Example: Here is one kind of mouse in the book but these are all the other kinds of mice.

Complexity:

  • Enlargement: for things at distance, for small items in complexity and for literacy
  • Overall ability to use settings and apps to reduce complexity of images.
  • Studying facial expression in photographs and videos: salient language of faces matched to voice (auditory). There can be instruction about facial expressions that match the auditory information.
  • Salient feature discussion in photographs and text.
  • Increasing spacing of words and sentences to reduce complexity of array.
  • Masking: complexity reduction with tools in Photos.

Distance:

  • Videos on the iPad: to bring information about events and concepts that occur at distance: Example: We are reading about giraffes. I think about providing a child with access to where that animal might live and how they move.
  • Access to distance classroom events: Examples: learning song hand movements for circle time.
  • Community access: taking photographs of signs and environmental materials that can be explored on the backlighted, near placed iPad.

“Duckness: How Do We Know?

Look at this series of pictures. (From American Printing House for the Blind website)

How can very young children with intact visual skills understand that these are all ducks?

They understand “Duckness”.

They have a keen understanding of the salient features (Roman-Lantzy literacy) that make up this “Duckness” because of shared visual experiences with others and with access to pictures, TV and movies that feature ducks. This develops effortlessly for children with intact visual skills.  Without direct instruction, they understand that real ducks are different sizes, colors, and ages. They understand that ducks can be seen in different perspectives depending on where and how they are standing. They understand that ducks can be flat in pictures. They understand that ducks can be symbolic in toys, signs, pictures, colored cartoons and in black and white drawings.

Our children with CVI lack this visual access to “duckness”. They lack the expanded and repeated knowledge about ducks. If they have seen a duck, their idea of “duckness” is limited to that one duck. Due to reduced eye contact with people and with reduced eye to object abilities, adults do not explain the shared salient features that all ducks share.

As adults serving children with CVI, we should be aware of this limited access and limited understanding that can occur in 3D and 2D. We must create opportunities to expand children’s access matched to their assessed functional visual skills measured with the CVI Range (Roman-Lantzy 2007). We must evaluate all our materials with this visual access limitation considered. We must adjust our own interactions and instructions to include salient feature, comparative language (Roman-Lantzy).

Visual Experience, Joint Attention and Salient Features

I went to a wonderful workshop this month with Dr. Roman-Lantzy. The topic was “Assessment and Strategies for Children in Phase III” (as measured on the CVI Range Roman-Lantzy 2007).

Some of the many things we talked about included:

  • Visual inaccessibility at distance for children scoring in Phase III (CVI Range Roman-Lantzy 2007)
  • How vision, cognition and language are linked.
  • How joint attention in typically developing, sighted children helps build these visual, cognitive and language skills.
  • How vision, cognition and language skills are based on the child’s experience.

It got me thinking about my own daughter’s visual, cognitive and language development. She was a typical developing toddler with full visual access.

We lived on our sailboat in Boston Harbor. We were surrounded by ducks daily. My daughter would see these ducks everywhere, everyday. (visual experience)

When she looked at or pointed to the ducks, we shared gaze to the ducks and I would label this animal: “Duck” (shared gaze, language)

As she language skills grew, she would begin to point and label them as “Duck” as well (building language and shared gaze).

When we traveled on land, she began to label other animals as ducks. She understood that dogs, cats and other birds we saw were not human but animals (cognitive). She over- generalized that any animal that was not human was a “duck”.

Sharing her gaze and sharing her experience, I pointed out the salient features that made these other animals different and labeled them as different. “No. That is a dog, he has 4 legs and is furry”. (cognitive, shared gaze and salient features).

Very soon, my daughter was able to use her cognitive comparison skills to label each animal she saw with the correct name based on the visual salient features: shape, number of legs, how then moved, where they lived, how they sounded.

For children in Phase III, supporting children’s visual, cognitive and language skills must be carefully planned, based on experience and presented at near by providing supports around salient features. They must be presented in planned, accessible ways due to the inaccessibility of distance events and materials.  This link must be facilitated to build visual, cognitive and language skills by comparing and contrasting visual attributes that are experienced, highlighted and shared.
