Structure of today’s math education system
Closed layered architecture based on:
• lack of subject understanding in the early layers.
• minimization of teaching duties in the final layers.
• life long teaching with:
• curricular-oriented ”knowledge pushing”.
![Page 5: Educational Design Patterns in Mathematics Ambjörn Naeve The Knowledge Management Research group Centre for user-oriented IT Design (CID) Numerical](https://reader036.vdocuments.mx/reader036/viewer/2022062620/551a8303550346b52d8b5797/html5/thumbnails/5.jpg)
Problems with today’s math education
It does not:
• promote understanding.
• support personalization.
• integrate mathematics with human culture.
• stimulate interest.
• integrate abstractions with applications.
• support transition between the different layers.
![Page 6: Educational Design Patterns in Mathematics Ambjörn Naeve The Knowledge Management Research group Centre for user-oriented IT Design (CID) Numerical](https://reader036.vdocuments.mx/reader036/viewer/2022062620/551a8303550346b52d8b5797/html5/thumbnails/6.jpg)
Possibilities for improving math education
• visualizing the concepts.
• interacting with the formulas.
• using ICT to increase the ”cognitive contact” by:
• personalizing the presentation.
Promoting life-long learning based on interest by:
• improving the narrative by:
• showing before proving.
• focusing on the evolutional history.
• routing the questions to live resources.
• proving only when the need is evident.

A Knowledge Manifold
• is designed in a way that reflects a strong effort to comply with emerging international IT standards.
• can be regarded as a Knowledge Patchwork, with a number of linked Knowledge Patches, each with its own Knowledge Gardener.
• gives the users the opportunity to ask questions and search for live certified Knowledge Sources.
• is a learner-centric educational architecture that supports question-based learning.

A Knowledge Manifold (cont.)
• allows teachers to compose components and construct customized learning environments.
• makes use of conceptual modeling to support the separation of content from context.
• contains a conceptual exploration tool (concept browser) that supports these principles.
• has access to distributed archives of resource components.

The seven different Knowledge Roles of a KM
• The knowledge cartographer
• The knowledge composer
• The knowledge librarian
• The knowledge coach
• The knowledge preacher
• The knowledge plumber
• The knowledge mentor
• constructs context-maps.
• fills the context-maps with content.
• composes content components into learning modules.
• cultivated questions.
• provides live answers.
• connects questions with appropriate preachers.
• provides motivation and supports self-reflection.

Att räkna med x är svårt.Jag förstod det aldrignär jag gick i skolan.
Barn, vi ska nu börja räkna med det där mystiska talet x som ni alla har hört talas om.
Jag kommer aldrigatt begripa det här!
Just det, precis som jag trodde, jag kan helt enkelt inte förstå det här!
