Using only elementary geometry, determine angle x. Provide a step-by-step proof.
You may only use elementary geometry, such as the fact that the angles of a triangle add up to 180 degrees and the basic congruent triangle rules (side-angle-side, etc.). You may not use more advanced trigonomery, such as the law of sines, the law of cosines, etc. There is a review of elementary geometry below.
New Zealand computer scientists have developed Eve, an affective tutoring system (ATS) which can adapt its response to the emotional state of children by interaction through a computer system. The researchers say their teaching system, dubbed ‘Easy with Eve,’ is the first of its type and add they ‘wanted to create a virtual teacher capable of reading and understanding body language and facial expressions to ensure that it has the attention of students.’
A conversation with Jeremy Roschelle about technology in K-12 math and science education.
This teacher resource, TeachEngineering.org, helps teachers enhance learning, excite students and stimulate interest in science and math through the use of hands-on engineering.
U.S. students are spending more time on math and reading and less on other subjects, an apparent consequence of the No Child Left Behind law.
Roughly two-thirds of elementary schools surveyed by the nonpartisan Center on Education Policy reported increasing math and reading time since the law was passed in 2001.
