XML (eXtensible Markup Language) comes virtually unchanged from the ISO 8879 standard SGML for the implementation of markup languages. It is a general purpose specification that aims at representing with simplicity documents with high quality and usability.
Examples of markup languages coming from xml are xhtml, mathml, musicml, graphml and svg. Applications like OpenOffice use the ooxml file format to represent word processing documents, spreadsheets, presentations and charts. This file format is essentially a zip file containing xml documents.
Although it is very similar to xhtml, the html specification is not a xml markup language.
Constructionist learning is inspired by the constructivist theory that individual learners construct mental models to understand the world around them. However, constructionism holds that learning can happen most effectively when people are also active in making tangible objects in the real world. In this sense, constructionism is connected with experiential learning, and builds on Jean Piaget's epistemological theory of constructivism.
Seymour Papert defined constructionism in a proposal to the National Science Foundation entitled Constructionism: A New Opportunity for Elementary Science Education as follows: "The word constructionism is a mnemonic for two aspects of the theory of science education underlying this project. From constructivist theories of psychology we take a view of learning as a reconstruction rather than as a transmission of knowledge. Then we extend the idea of manipulative materials to the idea that learning is most effective when part of an activity the learner experiences as constructing a meaningful product."
Moodle can be a tool consumer or a tool provider. See the documentation LTI and Moodle for further details.
Established in 2006, Mahara is the result of a collaborative venture funded by New Zealand's Tertiary Education Commission's e-learning Collaborative Development Fund (eCDF), involving Massey University, Auckland University of Technology, The Open Polytechnic of New Zealand and Victoria University of Wellington.
Released in Feb 2007 Mahara is a fully featured electronic portfolio, weblog, resume builder and social networking system, connecting users and creating online communities.
Mahara is designed to provide users with the tools to demonstrate their learning, skills and development over time to selected audiences.
Meaning `think' or `thought' in Te Reo Maori, the name reflects the project's dedication to creating a user-centred life-long learning and development application as well as the belief that technology solutions cannot be developed outside the considerations of pedagogy and policy.
