Aims
A Topic Study Group is designed to gather a group of congress participants who are interested in a particular topic in mathematics education. For ICME-12, the Topic Study Group is the major arena for participation.
The purpose of TSG 30 is to gather congress participants who are interested in research, development or teaching experiences that focus on mathematics education in multilingual, intercultural and/or multicultural situations. This TSG will include presentations and discussions of the state-of-this topic area and new trends and developments in research and practice in mathematics education in multicultural and/or multilingual environment. Contributions related to TSG 30 will be around issues and questions such as:

• What is distinctive about the learning and teaching of mathematics in multicultural and multilingual settings?
  
• How do curricula and policy take account (or not) of cultural and linguistic diversity?
  
• How do methods of assessment and evaluation take account of cultural and linguistic diversity?
  
• How does/should teacher education take account of cultural and linguistic diversity?
  
• What is the experience of education systems that have changed the medium of instruction in mathematics?
  
• What is the experience of education systems that use a former colonial language as the medium of instruction in mathematics?
  
• How does/should the teaching and learning of mathematics adapt to changes in cultural and linguistic diversity e.g. In the light of migration, political instability, etc.
  
• How can mathematics teaching respond to the oppression of cultural and linguistic minorities?
  
• How does mathematics teaching contribute to the oppression of cultural and linguistic minorities?
  
• What is distinctive about mathematics learning out of school in multicultural and multilingual settings?
  
• What theoretical perspectives on cultural and linguistic diversity are most helpful in investigating the teaching and learning of mathematics?
  Presentations on the above issues and questions could include the following types of studies:
  
• Empirical proposals with an anthropological, sociological or educational focus.
  
• Theoretical proposals about multicultural, multilingual and/or intercultural education and its relation to mathematics.
  
• Descriptions and analyses of teaching experiences in multicultural and/or multilingual environments.
  
• Analysis and/or evaluation of syllabi or descriptions of relevant practices regarding the preparation of teachers working in multicultural and/or multilingual environments.
  
• Description and evaluation of educative resources that support intercultural and/or multilingual education (audio-visuals, manipulatives, computer programs, bibliographies, etc.)
  
• Bibliographic surveys related to the issues and questions above with analysis or critical comments.

Guidelines for submission
TSG 30 will meet for four sessions of 1.5 hours each. The structure and organization of these sessions will depend upon the proposals submitted.
The organizing team invites submissions of proposals fororal presentations or posters relevant to the aims and focus of TSG 30 as described above. We expect that most contributions will address one or more of the issues and questions identified above. The official language of the congress is English and proposals should be presented primarily in English. Further guidelines for submission are as follows:

• Brief proposals for papers and posters (1000 - 1200 words) should be submitted electronically by Nov 1, 2011 both through the TSG 30 online submission system at the ICME-12 official website and by email to the co-chairs of the TSG 30.
  
• Indicate whether your proposal is for a poster or an oral presentation. If your proposal is accepted, you will be invited to prepare a paper of no more than 8 pages in the ICME-12 template to be submitted through the TSG 30 online submission system by 10 April 2012. The template can be found at the ICME-12 website.
  
• Poster presentations will be allocated time for discussion.
  
• Time allocation and other details (parallel or not) about the oral presentations would be finalized depending on the number of proposals received.
