  1. Math Forum Internet News - Math Forum
    An electronic newsletter sent out via e-mail once a week to those who subscribe, archived on the Web and as a Web discussion. It offers site tips (what we have at the Math Forum and how to find it), notes about new math onsite or on the Internet, questions and answers from the Math Forum's interactive math projects (Ask Dr. Math, Problems of the Week), suggestions for K-12 teachers and students, and pointers to key issues in mathematics and math education. more>>

  3. Proof - Mariotti, Maria-Alessandra; and Pedemonte, Bettina, editors
    Archives of the quarterly "international newsletter on the teaching and learning of mathematical proof." Articles have included "The effect of using Transparent Pseudo-Proofs in Linear Algebra," "Beliefs and beyond: hows and whys in the teaching of proof," "Is this a coincidence? The role of examples in fostering a need for proof," "Teacher's perspectives on 'authentic mathematics' and the two-column proof form," "Teachers modify geometry problems: from proof to investigation," "Intuiting the fundamental theorem of arithmetic," and "The interplay among gestures, discourse, and diagrams in students' geometrical reasoning." For issues dating back to 2009, link to articles from their original publications, which include journals such as Educational Studies in Mathematics, Journal of Research in Mathematics Education, Mathematical Thinking and Learning, and The International Journal of Mathematics Education; for older newsletters, going all the way back to 1997, Proof offers only bibliographic listings. more>>
