Designing a Learning Organization

• Is about …– To support a miniature society

• By providing various functional services such as…– Knowledge Aggregation, Dissemination, and Creation

• Using effective forces to improve service qualities

• Not only about …– Individual performance– Statistical metrics of individual performance

Creator of the Four forces

• Lawrence Lessig:– Law Professor at Stanford

University– Author of the following books:

• And most recently: REMIX

What are the four forces

• Architecture/Law <> Pre/Post Constraints• Market/Norm <> Pull/Push forces

Architecture

• A Pre-Emptive Force:– The stable properties of a system that constraints

the activities of its inhabitants BEFORE they act.

Example: The Great Wall of China

Law

• Enforceable consequences AFTER certain rules are broken …

- Only if it can be enforced.

Norm

• A force that expels or pushes agents to act in conformity.– It can be embarrassing to be different, even just a

little bit.

http://www.faithdoubt.com/be-a-little-different

How do we use these forces?

• If we treat schools as miniature societies …– We may use “the forces” to improve the performance

of engineering schools as service agencies.

• but, what are the goals of our schools?– Providing knowledge? Nurturing engineering culture?

• Then, how do we start testing these ideas?– Start with two consecutive courses at THU IE Dept.

• Data Structures and Algorithms• Database Concepts

Conceiving a Service Product• Goals of our Knowledge Provisioning Service

– Knowledge Aggregation• Aggregate people and resources• Aggregate experience and traditions• Aggregate momentum/interests

– Knowledge Dissemination• Disseminate to fellow students• Disseminate to other dept/schools• Disseminate to the society

– Knowledge Creation• Create knowledge based on incremental aggregation• Create knowledge based on cross-pollination• Create knowledge based on innovation

A Pact with the students• The goal/requirements were developed with

iterative inputs from students• All students are informed in the beginning of the

course, that our collective goal is – not to just get a passing grade on one course, – but to exercise our rights and responsibilities

to benefit-from and contribute-toknowledge provisioning services.

• They are encouraged to integrate any content knowledge from other courses and their life experience.

The first bit of Remix

• Let’s meet the students at the beginning of the semester…– Establishing a vocabulary amongst the students– They are relatively shy and not so well prepared…

• How do we communicate with the students in their “local” language?– The first bit of Remix

» Video excerpts from Prison Break

Goal-oriented architectural plans

• Technical Architectures– Choosing between various dialects of scientific languages

to express the technical content• Organizational Architectures

– One instructor lectures to many students– Many students prepare lectures to help others– Team-based structures to facilitate co-opetition

• Workflow Architectures– How do we choose between different format of

student/instructor interactions to enforce learning?• Weekly lectures, recitations, homework submission standards, …

Some Technical Decisions

• Under Tsinghua IE’s environmental context:– We require students to use at least two languages,

and use as many complementary tools as possible.• Most students will need least 5 languages, many learned

close to 30 different new languages and tools in one semester.

• All students has a series of required homework, create an executable programming language from scratch.

• All homework are managed using networked version control systems (SubVersioN, a.k.a. SVN)

– Computational literacy is the key, the more they learn, the faster and easier it gets.

Technologies enables new possibilities

A quick demonstration of technical possibilities…

Organizational Decisions

• To instill a societal context, all students are considered a member of the “Knowledge City”.

• Teams’ headcount cannot exceed 9, and each team is divided into three functional sub-teams.– Model for Data Management– View for Human-Machine Interactions– Controller for algorithm/process definition

• The organizational policy is modeled after the practice of Extreme Programming®

Workflow Decisions

• Classroom is a venue for “Town Hall” meetings– Students are to actively demonstrate their learning

progress, not just to passively listen to some lecturers.

• Stringent requirements for student-prepared lectures. At least two rehearsals before they go-live. Afterwards, a review lecture must be prepared and presented the following week.

• All teams might be randomly selected to present theirweekly progress.

The Pre-Emptive Forces• Technical Architecture:

– The vocabulary, grammar, and the application context of a scientific language, pre-determines the cognitive scope of students’ technical knowledge.

• Organizational Architecture:– Effective interaction mechanisms amongst

students/lecturers could pre-emptivelyeliminate communication bottlenecks

• Workflow Architecture:– Creates learning experiences that can be reproduced

and managed in prescribedprocess patterns

Laws that complements Architectures

• Laws should specify the consequences of policy violation.– The ability to enforce the law, as well as – The strength of punishment

• Example:– Late assignments are:

• Punishable by point deduction– Plagiarism are:

• Manual/Automatically detected?

The Power of Law

• The Power of Reasoning– Are students aware of the consequences?

• Their technical vocabulary helps them to effectively describe what they might have violated.

• Their organizational structure may help them filter the illegal intellectual content/activities

• Their workflow patterns will further reduce the unnecessary mistakes, and identify the differences between aggregation, dissemination, and creation

– The process of claiming a creation requires iterative and community-based reasoning.

Market and Intellectual Currencies

• There are many currencies in the marketplace• Three currencies are discussed here:

– Student Grades• Who gets higher grades?• How to motivate students by grades?

– Student feedback on teaching• Is this a fair exchange?

– Time as a currency• Time spent on improving the learning organization?

Norm and Peer Pressure

• The right to be different• A shared value across knowledge city

– Why is “sharing” good?– Share the vision of contributing “free” knowledge.– The effect of “free” to the infrastructure and

architecture of “Knowledge City”.• How to instill an engineering culture?

– Find/Create one’s own voice…– Stephen Covey’s 8th habit

• “Find your voice and inspire others to find theirs.”

A bit of Remix

• Lessig’s latest book, Remix, talks about the civil rights and case studies on the “Remix” copy-righted intellectual material.

• Let’s watch a 3 min. video of “Remix” at Tsinghua.– The lecture was on “Applications of Data

Structures and Algorithms.”– A typical in-class workflow is illustrated in the

video

The whole is greater than the sum of its parts!

Balance and Symmetry

• Designing organizations is about checks and balances! The four forces are balanced in their complementary directions. Before/After, Pull/Push, makes it rather complete to cover all angles of social dynamics.

• The four force framework is symmetrical, becauseapplies to a broad range of scales and types of social dynamics it explains. Its basic principles would apply to a small engineering class, or a large engineering school.– This framework was originally conceived by Lessig, for the

explanation of the entire Internet-infested society.

How can we apply it?

• The four forces can be used as a shared vocabulary to describe the dynamic properties of learning organizations.

• A curriculum design workflow may be deduced from the four forces:– Choose architectures to fit the learning goals– Define rules based on architectural capabilities– Choose fair grading policies to encourage learning

(Market)– Establish a norm that values knowledge sharing

Conclusion

• One or two courses may not be considered a curriculum, – but it could have a tipping effect of students’ overall

learning behavior.– A good starting point to implement CDIO, without too

much political uphill battle.• We might learn a few tricks from a lawyer,

(Lawrence Lessig), who cares about the philosophy and new civil rights primarily established by a great engineer, Richard Stallman.
