Information Technology in Education Lessons
from Computing in a Large Research University
Steven R. Lerman Class of 22 Professor and
Director, MIT Center for Educational Computing
Initiatives

I gave the wrong address for the lecture notes.
The correct URL is
  • http//web.mit.edu/lerman/www/Madrid2007
  • You should be able to download files from there.
  • Some of these files are large, so do this from a
    reasonably fast Internet connection.

Case 3 Formulating Strategy for Academic
Computing
  • Background/History
  • Council on Educational Technology
  • Major Outcomes
  • Lessons

4
The Council on Educational Technology was
appointed in the fall of 1999 to guide MITs
strategy in using technology to enhance the
quality of education.
Strategy Formation Process
5
  • However
  • The Council did not try to define MITs approach
    to educational technology for all time
  • The Council does not have operational
    responsibility for MIT activities
  • The Council did not limit initiatives by
    departments, schools, or centers

6
Caricature Models for MIT
Venture-tech

Flex-tech

Forever-tech
Global-tech
Ed-tech
8
MITs choices in the use of educational
technology must fit the Institutes mission and
the core beliefs expressed by faculty, students,
alumni, and staff. These core values and
beliefs fall into three categories
Foundation of Strategy Decisions
  • Inseparability of education and research
  • Uniqueness of MIT community
  • MIT Values -

9
Five Initiatives Arising from Process
  • Technology Enabled Active Learning
  • OpenCourseWare
  • DSpace
  • iLabs
  • The Singapore-MIT Alliance

10
Task Force approach with all constituencies
includedExtensive use of outside consultants to
support and push processExamined core values
and competenciesFocus on big picture
strategyLeft tactics for operating
organizationsUse of interviews to gather data
about opinionsMajor consultation effort for key
actions
Lessons from aspects of MIT process
11
Case 4 The iLab Project- Lab Experiments over
the Internet
  • Problem Statement
  • Some Examples
  • Technology Approach
  • Dissemination

12
Statement of the Problem
  • There is enormous educational value in hands-on
    laboratory experiences, but
  • conventional laboratories are expensive and
    have complex logistics
  • Scheduling, equipment cost, lab space, lab
    staffing, training, safety
  • conventional labs dont scale well and cant
    easily be shared
  • All institutions must own all labs

13
The iLab Vision
  • Many labs shared worldwide
  • Some are unique (unreachable locations, rare
    materials)
  • Many simple labs

Campus network
Internet
Client
Service Broker
Lab Server
University Databases
14
The iLab Vision
  • GUI to lab
  • Integrates useful generic tools (graphing,
    numerical analysis, simulators)
  • Allows for remote collaboration and tutoring

21
Uniqueness of iLabs
  • Pedagogy
  • iLabs introduce laboratory experiences in
    subjects that didnt have them before.
  • iLabs enable laboratory experiments at most
    opportune moment in curriculum.
  • iLabs allow students to perform experiments in
    pleasant environments at times of their choice
  • iLabs minimize frustrations with hardware
  • iLabs allow students to work in a stop-and-go
    mode

22
Demonstration The MIT Microelectronics lab
  • The web site
  • http//openilabs.mit.edu
  • Provides open access to some of the labs.

23
Uniqueness of iLabs
  • Logistics
  • iLabs can be located in places inaccessible to
    students
  • iLabs hold unique scaling characteristics
  • round the clock usage
  • from anywhere in the world
  • Economics
  • iLabs can be broadly shared ? fundamental change
    in economics of the lab experience

24
iLab Design Goals
  • Scaling usage of online labs to a large number of
    users
  • Allowing universities to share access to
    equipment
  • Single sign on to labs at multiple universities
  • Freeing lab owner/operator from administration
    (i.e. authentication, authorization, storage of
    results, archiving of data, etc.) of users from
    other universities
  • Allowing universities with diverse network
    infrastructures to interoperate and share
    resources

25
Project Boundaries
  • Our architecture doesnt deal with specific
    hardware and software interfaces to lab equipment
  • Our architecture is intended to be compatible and
    complementary with commercial software such as
    National Instruments LabView and analysis
    packages like Matlab

26
The Case for Web Services
  • Web services represent a new version of an old
    concept -- they allow one computer to invoke a
    procedure (method) on another.
  • They are platform and vendor independent (we
    routinely use a Java client ? a Windows XP/.NET
    Service Broker ? a Windows 2000/2003 lab server.
  • Because they are usually based on http that we
    all use to access the web, they work well with
    campus networks.
  • They allow a computer to define how it will share
    its resources in a well-defined (WSDL) interface.
  • The iLab Shared Architecture builds on top of the
    current generation of web services.

27
iLab Experiment Typology, 1Waves of Development
  • Batched Experiments (2003-2005)
  • The entire specification of the experiment is
    determined before execution begins.
  • The user need not remain online while experiment
    executes.
  • Interactive Experiments (2004-2007)
  • The student client portrays virtual lab equipment
    (GUI).
  • The student can interact with experiment
    throughout its course.

28
iLab Experiment Typology, 2Waves of Development
  • Sensor Experiments (?2007-?)
  • Publish and subscribe based architecture
  • Triggers and event-driven data monitoring
  • Flexible data analysis
  • Data archive

29
Lab Providers Goals
  • Lab Providers Goals
  • To share a lab with colleagues students through
    the Internet.
  • What a Lab Provider Does Not Want To Do
  • Register 100s of student accounts for other
    peoples students.
  • Store experiment results for students from other
    institutions and decide when they can be deleted
    or how to archive them.
  • Decide who can view whose experiment results,
    especially when it involves setting policy for
    another universitys courses.

31
Lab Provider Responsibilities
  • The Lab Server team
  • must connect the lab server to the Service Broker
    by implementing the Service Broker to Lab Server
    Web Service API
  • will usually supply the student lab client
    software, which must implement the Client to
    Service Broker Web Service API
  • Client only communicates with the lab server via
    the Service Broker using these APIs

32
What a Lab Provider Does Not Want To Do
  • Register 100s of student accounts for other
    peoples students.
  • Store experiment results for students from other
    institutions and decide when they can be deleted
    or how to archive them.
  • Decide who can view whose experiment results,
    especially when it involves setting policy for
    another universitys courses.

33
Service Broker Responsibilities
  • The Service Broker is both a web application and
    a web service that
  • stores and manages student experiment records
  • provides mechanism for but does not specify local
    campus course and privacy policy
  • authenticates users and transmits credentials but
    not user IDs to Lab Server
  • manages workflow between client and lab server

34
Student Web Session
35
Student Service Broker SessionLife Cycle
  • The student contacts the Service Broker (SB) via
    a standard web browser.
  • The student either
  • registers for a new account, or
  • authenticates himself to the Service Broker
    (current implementation offers ID/password over
    SSL)
  • The SB lists the students group (class)
    memberships, and asks the student to choose an
    effective group for this session.
  • The SB lists the lab servers/clients available to
    that effective group, and asks the student to
    choose a client
  • The SB launches the lab client (often an applet)
    for the student.

Service Broker Administrative Services
  • Adding, modifying, and removing lab servers and
    clients.
  • Adding, removing, or confirming user access.
  • User management including assigning users to
    groups and modifying access rights.
  • Managing experiment records.

40
iLab Generic Services
  • User authentication (and registration)
  • User authorization and credential (group)
    management
  • Experiment specification and result storage
  • Lab access scheduling

41
Our Long Term Vision
  • Creating a movement within higher education (and
    potentially other levels) leading to global
    sharing of laboratory experiments over the net
  • Creating an informal barter economy to
    facilitate sharing of lab equipment
  • Sharing beyond access to lab equipment to include
    pedagogical materials and teaching experiences
  • iLab-ready experimental equipment and software
  • Sharing of time on national and international
    experimental equipment such as space-based
    experiments
  • Improving education through expansion of
    lab-based learning opportunities around the world

42
Making iLab software available
  • iLab software and documentation will be made
    publicly available
  • for comment postings followed by formal
    releases
  • Release under an open source license
  • Welcome comments and advice from anyone
    interested

43
What Have We Learned? 1 the students view
  • Students are intrigued and motivated by iLabs
  • Better student participation and higher scores
    than regular homework
  • Students dread real laboratories and appreciate
    iLabs convenience
  • Tend to work late at night (unpleasant to be in
    real laboratory)
  • Simplified interface minimizes frustrations with
    hardware
  • Students have trouble handling real-world data
  • Cant distinguish good data from bad data
  • Have difficulty manipulating data (graphing,
    extracting parameters)
  • Have difficulty comparing measured data with
    theoretical models
  • System problems detract from educational
    effectiveness

44
What Have We Learned? 2 Ad-hoc iLab
development and management does not scale
  • iLab developers are not IT specialists and want
    to minimize development work (want to reuse
    generic lab components)
  • iLab managers do not want to deal with individual
    user management
  • iLab consumers want to see single portal to
    multiple labs
  • Need an iLab Shared Architecture

45
Lessons from iLab Project
  •  
  • Breaking complex IT problem into collection of
    web-based services can be effective
  • Separation of responsibilities/roles is effective
    approach to organizing IT system
  • Design from real-world cases rather than
    hypotheses about functionality users want
  • Incremental approach to extending functionality
    over time can be useful

Useful Lessons from MIT Experiences
  • Diverse goals of university have led to
    distributed responsibilities and costs
  • Outsourcing vs. internal provision
  • Difficulty in knowing full costs of IT provision
  • Intergroup communication is crucial in
    diversified computing provision
  • MITs IT structure does some things well, and
    some things poorly
