BbWorld18 Session Post: Become a Bb Jedi: Move Students with Only Your Mind and UDL

Thomas J. Tobin
University of Wisconsin-Madison

The Star Wards universe is an accessible universe…a good metaphor for Universal Design for Learning.

Making an accommodation for one person is not universal design. Let us not talk first or only about people with disabilities when we want to address barriers.

Reframe the conversation. Unlearn what you have learned. Talk in a value neutral way about the benefits of an inclusive design.

What one strategy could he adopt to supplement-or even replace-her face-to-face message?

Texting, Short Video, Reminders, Online conferencing -> has to do with expanding learners options.

learner engagement representing info action choices.

Give time estimates it would take to read something.

Universal Design for Learning is “plus one” thinking. If there is one way for students to interact with an assignment, make 1 more way.

ULD = access (no matter why)

“We want a situation that is goof for everybody…part of it is thinking about what has to happen at the level of design that makes accommodation less necessary.” –Sam Johnson, CAST

5 Strategies for UDL

    Start with text…start with a script have some notes, you can provide it later when you create other media out of it.
    Make alternatives. (HTML version, pdf version etc..)
    Let ’em do it their way where you’d can – design assignments where students can choose how they respond (written, video, audio etc). Do it in a directed fashion
    Go step by step
    Set content free (accessible 24 hours a day) and from formatting. Put examples in video format rather than resident software…

Ask about the question they get all the time, problem on tests and quizzes and where did they want you to say it a different way. Train faculty, IT, everyone that supports faculty members.

    Learn Integrations Overview

    Moving Integrations to SaaS and Ultra

    Scott Hurley, Mark O’Neil and Lynn Zingraf – Blackboard

    What is your Migration Strategy

    • Define long term goals
    • Prioritize integrations
    • Know your platform options
    • Know your API options
    • Seize the Opportunity
  • Define your Longterm Goals
  • What are your long terms goals? Defining your goals in context of what you know today and where you think you are headed has substantial impact on your migration path in both the short and long term.
      • Transition to SaaS
      Move to Ultra
      Adopt REST for ease of development/delivery?

    Prioritize Your Integrations

    • One reason you may be sitting here is that you already have an investment in using integrations to customize your faculty’s and student’s teaching & learning experience.
    • A key consideration for your migration path is the importance of each of your integrations and the feasibility of delivering them on the currently available architecture.
    • Knowing the importance of each integration, your options for delivery of that integration, and available APIs each help you to prioritize and schedule migration of your integrations as a project
  • 1 Learn, 2 Experiences (Original, Ultra), 3 Deployments (Self-hosted, Managed Hosted, SaaS)
  • Know your API Options
  • Bb offers a range of options for integrations – what you use depends on what your trying to accomplish.
  • Building Blocks => LTI / LTI+REST
  • Rest APIs <- ->
  • Partner Cloud
  • Seize the Opportunity
      • Redesign the user experience
      – no longer bound by Blackboard JSP constraints
      – Meet change in goals
      Use your untapped resources
      – REST and API language agnostic!
      – You no longer need Java Expertise
      Expand availability to non-Blackboard resources
      – REST and API integrations run external to your LEARN server
      – Make them available to additional portals and services

    Seize the opportunity to NOT migrate and integration.

    REST APIs

    B.B. adopted REST as our forward architecture for providing APIs to integrate with Blackboard products

    Rest API Progress

    IMS Standards Support

    LMS LTI

    LTI provides a secure connection between a learning tool and a platform like Blackboard learn. It is http-based and provides a context on launch.

    LTI Differences

    How does Blackboard Support this in Original?

    LTI 1.3 (not supported yet)

    • Based on 1.1
    • Improved Security model
    • Separates the security model from the rest of the spec, allowing IMS to more easily keep the security model up to date
    • Designed specifically to align with the services of LTI Advantage
    • Includes improved documentation and around implementing and migration
  • LTI Advantage
      • Package of extensions that work with LTI
      All bout the usability of the standard
      Creates a dream work for new features
      Enables deeper integration with any tool

    BbWorld Devcon Session Post – Building Learning Tools for Blackboard Using the Tsugi Application Environment

    Dr. Charles Severance
    University of Michigan
    School of Information

    Tsugi Building Learning Applications

    Tsugi (Japanese for “next”) provides a way to develop and host “learning tools” in an Application Store. Tsugi tools can be seamlessly integrated into existing Learning Management Systems and Google Classroom. As part of its core architecture, Tsugi implements standards like IMS learning Interoperability, IMS Content ITem and Google Classroom.

    TsugiCloud – A Free App Store for Open Source Tools from the Apereo Foundation. Teachers and LMS Administrators can quickly and easily install the tools from TsugiCloud into their LMS or Google Classroom. Software Developers can participate in the development of new these tools through the Apereo project.

    …provides a free, scalable

    The learning ecosystem of future

    • We need a way to build learning tools quickly w/out waiting for LMS upgrade
    • IMS learning tools Interoperability (LTI) provides a way to integrate learning tools
    • The LTI family of standards is getting more robust (and complex) all the time
    • We need to move from building LMS tools to building better teaching tools
    • We need to enable LTI tool development at a campus or even a course level
  • Why Use Tsugi?
      • 100% open source project part of the Apereo foundation
      Increases learning tool developer productivity
      Supports IMS LTI Standards

    Getting Started with Tsugi

    Developer Training – https://www.tsugi.org/lessons

    Developer Environment is also the AppStore environment

    As a test harness that allows you write code quickly and build application quickly.

    Https;//github.com/tsugitools/iframe – Iframe Tool

    Summer Project: TBlocks

    • Tsugi PHP Tools in post-GDPR world
    • TBlock model
      – each tool is a container
      – no direct access to the db
      – Interacts with core Tsugi using a. Local API backed by a REST web services
      – Launch data – course/ user / link / result
      – Uses link /result scoped JSOn
      – accesses a link scoped scoped key /value store
      – Can support more than php easily (I.e. python / django / node)

    Big Idea – Building a Simple Tool – Look at Tsugi – Try it and give feedback. Mature enough to run a local App Store or use the cloud App Store.

    BbWorld18 Devcon Session Post: Collaborate Ultra: WebRTC and our MCU

    What is WebRTC?

    WebRTC is an open source project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose

    • Web Real-time Communication
    • Interoperation across vendors
    • Standards managed by W3C and IETF
    • Open-Source Mobile
  • Why use WebRTC
      • Gets audio/video to/from a and b fast
      Critical mass across browsers and devices
      – no need to reinvent the wheel
      – lower friction due to “no plugin” installation
      – User control over permissions
      Easy to work with
      – Leverage HTML5/Javascript
      – Lots of APIs (getUserMedia,RTCPeerConnection, RTCDataChannel, getStats)
      Click a link: connected!
      A lot of hype but perhaps not overhyped

    Collaboration WebRTC Adoption

    • Collab’s choice of WebRTC was not so straightforward
    • in 2014
      – Poor browser support (chrome early Firefox)
      – Codec wars in effect
    • Collaborate’s choice: Use WebRTC to deliver browser-based conferencing
      – What about Collaboration original
      – Only Chrome was mature enough at the time to meet market expectations
      – Multiple HQ videos with good sync
      – Desktop Sharing
      – Other browsers use flash required (one video no desktop sharing)
      – We’ve been adding additional browsers as they mature Firefox in 2016, Safari 11 and Edge are on the way)
      – Flash end of life: 2020
  • Browser Implementations
      • Codec Wars
      SDP vs ORTC
      Browser Compliance
      Browser Permissions

    Codec Wars:

    • Audio agreed to: OPUS
      – High speed collision between technologies
      – Low bit rates for speech
      – High bit rates for music
      – Forward Error Correction
    • Video- not so much
      – VP8 from the Google Camp
      – H.264 from the Cisco/Apple/Microsoft
      – No significant performance difference, we don’t care!
      – Patents main blocker for H.264
      – Finally Solved by MPEG LA (via Cisco) giving it away.
  • SDP vs ORTC
      • How to describe the details for the media session?
      – Capabilities and connectivity between peers
      Session Description Protocol
      – Text-based and very complex for multi-channel
      – Existing browsers use SDP
      – Even here, two different versions: Unified Plan vs Plan B
      Object Real-Time Communications
      – Simpler and less proscriptive
      – Microsoft used ORTC and not SDP for Edge

    Browser Compliance

    • After years of in-fighting we have a standard: WebRTC 1.0
      – Working Group first created in May 2011
      – Originally expected to finish end of Feb 2013
      – Last call Started October 2016
      – First candidate Recommendation: November 2017
    • Browsers have different degrees of adherence to standards
    • Adapter.js Serves to normalize subtle browser differences
  • Browser Permissions
      • Microphone/camera access
      The camera light
      User fingerprinting
      Local IP address enumeration

    WebRTC Connections

    • We’ve exchanged SDP; now how do we connect to send/receive audio and video?
    • Simplest case almost never works – users are very rarely connected to directly to the internet
    • Need to handle a wide range of possible network configurations
    • Network Address Translations
    • IPv4 address limitations: running out of IP Addresses
    • Works fantastically well for normal web requests
    • Terrible for real-time media
    • User Datagram Protocal
      – fast, buy lossy “best effort”
    • Transmission Control Protocol
      – reliable, but slow “guaranteed”
    • For real-time media, time is king: prefer loss over delay
    • Transport Layer Security
      – Encrypted, secure, private
      – For UDP or TCP
  • Collaborate’s MCU – Core Technology
  • Peer to Peer – WebRTC is about connecting two endpoints with media. How do you create a conference?
  • Multipoint Conferencing Unit
  • Selective Forwarding Unit
      • Hybrid
      Adaptable

    Bandwidth adaptation

    • Packet Loss: sequence Numbers
    • Latency: time stamp
      • How our MCU technology improves the experience
      – Differing bandwidth
      – Quantizing Modes
      – Three Bands
      – High bit rate (pass through)
      – Low bit rate
      – Ultra low bit rate

    Key Differentiators

    • prioritization
      – audio: by adapting quickly, we can ensure that video bandwidth does not interrupt audio traffic
      – video: high quality video for primary speaker and/or desktop sharing
    • Customization
      – Each viewer gets the best quality available to them,based on their bandwidth
    • Scale
      – Collaborate supports 500 users in a single session.
  • Future of WebRTC
      • Scalable Video Coding: VP9 vs H.265 -> VC1
      Data Channels
      – Chat/Subtitles
      – File transfers
      – Synchronization/Gaming
      An enabling technology: endless applications
      – AI agents: bots!
      – Internet of Things

    Future Adaptations for Collaborate and WebRTC

    • Prepare for Flash EOL (2020)
      – Safari 11 and Edge native support (on the roadmap)
      – Plugin for Safari 10 and IE11, and/or end support
    • Example feature Requests
      – Dedicated video channels (sign language, labs, presentations)
      – More Videos
      – Primary limitation is available bandwidth
      – Desktop Cursor Control
      – WebRTC desktop sharing is not VNC

    BbWorld18 Devcon Session Post: Integrating Learn with LTI and REST

    HOW TO INTEGRATE AN APPLICATION WITH LEARN USING LIT AND REST APIs

    Note: most of this session is in the “coming soon category”

    What are we trying to solve?

    • Integrate ISV(independent software vendor) tools with original and ULTRA Learn
    • Access to content
      – Publisher Text books
      – Open educational resources
    • Use of specialized “tools” not built by Blackboard:
      – Assignment
      – Test
      – Grading
      – Video Creation
      – Course Evaluation
      – Games
    • Better Security!!
  • Content Market (built into learn experience)
      • Publishers, LTI tools.
      Links bring up ISV UI
      Getting 3rd party content into LEARN seamlessly

    Your Experience

    • Tool Developer
    • Learn Administrator/Instructor/User
    • Ultra Experience
    • Building Blocks
    • LTI
    • REST API
  • LTI Advantage – four new specifications that work together
  • New Security Model based on existing standards
      • OAuth 2.0
      OpenID Connect (OIDC)
      JWT (JSON Web Tokens)
      Library support for most languages (see jwt.io)
      Better security (harder to crack)
      Asymmetric keys (not sharing keys between tool and LMS)
      New terminology to better match OAuth 2 terminology:
      – Tool (tool provider) – Client in OAuth 2.0
      – Platform (tool consumer or LMS) – Resource Server
      – Users
      – Grades

    New Security Model & Contract

    NEw Deployment ID for Tools

    LTI Resource Link (Formerly known as Basic LTI Launch)

    JWT and OpenID Connect Fields

    LTI 1.3 Core in a Nutshell

    LTI Deep Linking 2.0 (Formerly Content-Item Message

    LTI Deep Linking Request (from Platform)

    Assignment and Grades Service 2.0

    • Post a score from tool
    • Get result from platform
      -result does not necessarily equal score
    • Create line items (grade book columns) by the tool in the platform’s grade book
      – may or may not be associated with a resource
    • Requires OAuth 2.0 security model (bearer token, scopes)
  • Developer Portal – developer.blackboard.com
      • Rich set of RESTFUL APIs
      Well documented
      Use in conjunction with LTI
      – get information about a course
      – Gradebook schemas
      – Attempts for a user
      – Group Information
      – ETC.

    BbWorld18 Devcon Session Blog: Introduction to Attendance

    • Overview of attendance functionality
    • Feature/service architecture
    • Integration architecture
    • Impact and future guidelines
  • Attendance shows up in a roster view with students on left and tabular content on right with the Day, if they were present, late, absent and excused columns.
  • A grade can be calculated for it and it is added to grade book.
  • Principles for New Solution
      • Foundation for future integrations into product portfolio
      Separate application and data store, singer source of truth
      API First
      Take advantage of latest tech

    Service Architecture

    • Multi-tenant service, data serrated by unique user I’d
    • Application tier developed in java
    • Dropwizard library for API/controllers
    • JDBI for data access
    • Flyway for database scheme management
    • Deployed as docker containers on Kubernets
    • Postgres 9.6 for database
  • Integration Architecture
  • Security Architecture
  • Why did we choose this architecture?
    Building Functionality as a separate service has advantages.
      • Separate application & database adds no load to learn
      Natively built on REST API, easy to integrate into other products
      Standalone, small service can choose the most appropriate technologies for a given function
      Separate service can be tested and deployed in isolation.

    Integration Architecture

    • Standalone SaaS easily integrated across portfolio
    • integrate 3rd party services through developer portal (future)
    • API first (REST) enables complete access to service functionality through APIs
  • Blueprint for future work
      • Building services as separate has advantages can can be applied to broad set of problems
      Important architectural pattern that will help apply on larger scale over time
      Leads to tighter integration and more consistent functionality across product suite
      Services can be gradually rolled out and integrated Bb applications
      Scalability of entire eco-system will improve over monolithic application: more stable, more consistent and predictable performance
      Used in other areas besides attendance, box integration, cloud storage integration, Ultra institution pages.

    General Impact

    • Service based architecture is mostly transparent to end users, but affects developers and integrators.
    • Not all data I contained in LEARN anymore
    • Not all functionality is available via Java API anymore
    • Data will be aggregated into data lake
    • Functionality is exposed through REST APIs
    • Use REST APIs to future prof customizations and extensions.

    “Intuitive” is in the eye of the beholder.

    intuitive_cropped

    So I felt the need to compose a blog that reflected on an experience that we just had at our office and how it relates to how we approach our jobs supporting online/face-to-face/hybrid students and faculty. Our office recently relocated to a “new-to-us” location.  We really love the location and appreciate the way it improved our “esprit de corps”.  We did however notice one issue that had us perplexed.

    You see, we couldn’t figure out how to lock our inner-office doors.  There was a door knob, and a place to fit our keys to unlock our office doors, but we couldn’t lock the door using our keys.  We tried it with our individual keys, with our office master-key and even tried it on different doors, but to no avail.  We couldn’t figure it out.  Finally we just decided that the locks must be broken.  After all, why give us keys and a key hole, but no way to lock the doors that these key holes belong to.  Confident in our assumptions, we put in a ticket with facilities and asked them to come fix our problem.

    Well later that day a gentleman from facilities showed up and check out the doors.   He took one look at our “broken door-locks” and asked, “Did you push the button?”  The button?  We couldn’t find any button and we told him so.  Finally, he directed us to where the latch comes out of the door and told us to press in what we thought was part of the latch and low and behold, the doors locked!  Who would think to look for a locking mechanism on the side of the door, rather than make it part of the knob?

    What was intuitive for the facilities employee was NOT intuitive for us.  Now, in the moment, we all laughed and rejoiced in our new found ability to lock our inner-office doors.  A few hours later as I was sitting at my work desk, I realized that this situation related well to our jobs as instructional technology guides, helpers, trainers and designers.  What do we think is intuitive?  The learning activity, proctoring software or the LMS?  We live and breathe this stuff day in and day out, while our students and faculty may be experiencing it for the first time.

    We should be putting all of our documentation, course work, and interactions into this context.  Are we we forgetting the mechanical instructions when we design learning activities and just putting in the academic?  Do we design technology how-to documentation with an assumed level of experience?  Would taking this into consideration change how we approach support calls from students or faculty?  I think it would.
