    PoW taking place: Math problem-solving moment of the week

 "At first, I kept on thinking the denominator had to stay the
 same.... But after my realization, I tried out my
 new theory ..."

    REPORT ON IMPLEMENTATION OF K-12 STATE STANDARDS FOR MATH

    https://www.rand.org/pubs/research_reports/RR1529-1.html

 The RAND Corporation recently released revised findings from
 two surveys of the American Teacher Panel (ATP).

 To write Implementation of K-12 State Standards for
 Mathematics and English Language Arts and Literacy,
 researchers from the nonprofit institution analyzed several
 thousand teachers' responses to such questions as "Which of
 the following phrases best describes what 'modeling with
 mathematics' means to you?" The resulting report discusses how
 teachers use instructional materials to address state
 standards; teachers' perceptions about the content and
 approaches most aligned with their standards; and the extent to
 which they are asking their students to engage in practices
 aligned with their standards.

 In chapter 4, "Teachers' Perceptions and Practices Related to
 Mathematics State Standards," the authors observe that teachers
 engaged students at comparatively lower rates in two of the
 eight Standards for Mathematical Practice: "Look for and make
 use of structure" and "Construct viable arguments and critique
 the reasoning of others." The ATP surveys also revealed that
 teachers who serve lower-income students, as well as those with
 more years of experience in the profession, have different
 perceptions about the "aspects of rigor" targeted by particular
 standards. Those discrepancies could add up to classroom
 instruction that deviates among teachers covering the same
 standards content. Interpretations of what it means to "model
 with mathematics" varied, as well.

 Although the ATP provides a nationally representative sample of
 teachers, RAND's researchers focused on California,
 Louisiana, New Mexico, and New York. These four target states
 have received some investment to support implementation of
 standards from the Helmsley Charitable Trust, which provided
 funding for the 165-page work, now freely available to download
 (1 MB) from the RAND Corporation:

To assist in this, I created NCTM show specials from the conference this week in San Antonio. It will be hard to find better prices from Texas Instruments. Attached are the deals being offered.... The deals are time sensitive, so please check the cut-off dates for each educational dealer." - Dana, posted to the secondary (grades 9-12) discussion group of the Association of Math Teachers of New York State http://mathforum.org/kb/thread.jspa?threadID=2849339 -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- GEOGEBRA FOR DESKTOP https://blog.geogebra.org/2017/04/
geogebra-math-apps-for-desktop/ On Tuesday, the International GeoGebra Institute rolled out the latest version of its dynamic mathematics software for offline desktop use, bringing the user-interface of the GeoGebra apps from smartphones and tablets to Windows, Mac, and Linux computers. This week's release also includes a new full-featured equation editor in the Algebra View, which boasts enhancements such as sliders and checkboxes. In addition, an Insert Image Tool now works with webcams. GeoGebra, last featured here after the release of its first version that supported three-dimensional geometry, continues to be free of charge. Its global community has authored and shared over 750,000 freely available STEM curriculum materials: https://www.geogebra.org/materials Download GeoGebra's new desktop math apps to your computer here: http://beta.geogebra.org/download -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum at NCTM http://mathforum.org/ Online PD http://mathforum.org/pd/ Online Workshops http://mathforum.org/workshops/ Ask Dr. Math http://mathforum.org/dr.math/ Problems of the Week http://mathforum.org/pows/ Powerful Problem Solving http://mathforum.org/pps/ Mathematics Library http://mathforum.org/library/ Math Tools http://mathforum.org/mathtools/ Teacher2Teacher http://mathforum.org/t2t/ Discussion Groups http://mathforum.org/kb/ Join the Math Forum http://mathforum.org/join.forum.html Ask Dr. Math Books http://mathforum.org/pubs/dr.mathbooks.html Facebook https://www.facebook.com/themathforumatnctm/ Blogs http://mathforum.org/blogs/pows/ Twitter Feed http://mathforum.org/pd/twitter.html SEND COMMENTS TO: http://mathforum.org/electronic.newsletter/mfin.faq.html#feedback _o \o_ __| \ / |__ o _ o/ \o/ __|- __/ \__/o \o | o/ o/__/ /\ /| | \ \ / \ / \ /o\ / \ / \ / | / \ / \ An archive of all the Math Forum newsletters and directions for subscribing can be found at http://mathforum.org/electronic.newsletter/
