Major outcomes of the project were the draft of a precalculus textbook now being reviewed prior to field testing, and a series of independent study modules appropriate for use in mathematics education courses or as supplementary material in algebra and trigonometry courses. Earth Math materials focus on application of mathematics to real world problems and are intended to improve students’ problem-solving and decision-making abilities. The materials are also intended to demonstrate how to implement the National Council of Teachers of Mathematics standards in school mathematics courses. Separate sections of the… Continue Reading →

eric.ed.gov har udgivet: This report examines mathematical graphing utilities or function plotters for use in introductory algebra classes of more advanced courses. Each product selected for inclusion in this report is able to construct the graph of a given equation on the screen and serves as a utility which may be used by the student for an open-ended exploration of a mathematical concept or by the teacher as a demonstration tool. The products are classified into one of the following types: (1) general purpose graphing utilities; (2) demonstration tools; and (3) special utility programs. In general it was felt that the positive aspects of function plotters far outweigh the negative. The ability to automate the tedious process of plotting the graph of an equation enables students to examine more equations… Continue Reading →

eric.ed.gov har udgivet: “Informed math self-placement,” a program implemented at American River College in Sacramento, California, to determine students’ readiness for college-level math, has been in place for three years. This case study describes the development and implementation of math self-placement at American River. Math self-placement consists of a Web-based testing and information site that allows students, or potential students, to gauge their level of math proficiency prior to talking with a counselor or enrolling in classes. Math faculty members and administrators are hopeful that self-placement, as an alternative to traditional placement, will provide students with concrete knowledge and experience about math standards, since self-placement includes actual self-assessment instruments (tests), developed and approved by the college’s math faculty. American River’s experience in math self-placement is noteworthy in its potential to… Continue Reading →

eric.ed.gov har udgivet: This document presents materials that were developed for a presentation explaining how the Gordon Cooper Technology Center in Shawnee, Oklahoma, obtained state certification for the geometry and trigonometry program that is embedded in its residential and commercial construction program and enables its students to receive high school geometry or trigonometry credit and thereby meet the Oklahoma PASS (Priority Academic Student Skills) objectives for high school math credit. The document begins with a brief description of the presentation’s objectives and content. The remainder of the document consists of the following presentation handouts: (1) excerpts from Oklahoma legislation regarding high school graduation requirements affecting students attending technology centers; (2) the program approval letter sent to the technology center; (3) a description of the math program approval process; (4) information… Continue Reading →

eric.ed.gov har udgivet: Everyone knows that there is racial inequality in achievement returns from advanced math; however, they do not know why black students and white students taking the same level of math courses are not leaving with the same or comparable skill levels. To find out, the author examines variation in course coverage by the racial composition of the classroom. She hypothesizes that content coverage varies by classroom composition, because teachers respond to the needs and abilities of their students and make adjustments to teaching. More specifically, she asks: (1) Within advanced math courses with the same title, to what extent does content coverage breadth vary by classroom minority composition; (2) Within advanced math courses with the same title, to what extent does content coverage depth vary by classroom… Continue Reading →

eric.ed.gov har udgivet: In 1999, Richard Lee Colvin published an article in “The School Administrator” titled “Math Wars: Tradition vs. Real-World Applications” that described the pendulum swing of mathematics education reform. On one side are those who advocate for computational fluency, with a step-by-step emphasis on numbers and skills and the algebra-geometry-trigonometry-calculus sequence. On the other side are those who think students must engage with real-world problems that employ a variety of mathematical disciplines and deep learning of math concepts that comes from struggling with complex problems, comparing multiple solution paths, and learning from trial and error. To understand what it will take to bring the two sides of the mathematics debate together, first consider the approach each side takes to improve student achievement. One side wants to focus mostly… Continue Reading →
