Female tenth graders (n=217) were less likely than male tenth graders (n=219) to identify missing or irrelevant information in algebra problems. Female eleventh graders (n=234) were less likely than male eleventh graders (n=287) to solve problems with irrelevant information. Results indicate sex differences in knowledge of problem structure. (SLD)

Examines the reliability and validity of using a survey to gauge the percentage of time that algebra teachers use practices that are consistent with professional standards for teaching mathematics. Survey results from 28 teachers suggest that a composite of practices is quite reliable and somewhat valid but that it does not capture instructional…

Presque Isle (Maine) High School has offered a section of all-girls algebra for seven years. The intent was to narrow the gap between 11th-grade boys' and girls' math achievement scores and create a more comfortable learning atmosphere for girls. The achievement score gap has decreased from 72 to 16 points. (MLH)

Explores alternative strategies to solve algebraic equations that do not lend themselves to traditional methods. Examines one nontraditional equation by a graphical approach using a graphing utility and by a numerical approach using spreadsheets. Discusses new basic skills for algebra utilizing technology. Provides a computer program to solve…

Videotapes showed that two algebra classes containing Hispanic students with limited English proficiency differed in the extent of mathematical communication by students. In the more successful classroom, students' mathematical communication developed in small-group discussions and later spread to the large-group setting; computers were also…

Used data from groups of 376 and 273 algebra teachers to study the reliability of the Stages of Concern Questionnaire (G. Hall and S. Loucks, 1978) and explore changing it to a five-stage questionnaire rather than the seven current stages. Results confirm a lack of reliability but do not support a change to five stages. (SLD)

Presents research in which mathematics teachers and educational researchers ordered arithmetic and algebra problems according to their predicted problem-solving difficulty for students. Analysis of students' problem-solving strategies indicates specific ways that students' algebraic reasoning differs from that predicted by most teachers and…

Academic Systems Corporation is successfully producing courseware in beginning, intermediate, and college algebra using mediated learning, which provides students with instruction and exercises and teachers with feedback on student progress. The courses present students with real-world problems to solve. Users find the courses pedagogically sound…

Presents the hierarchical structure of quadrilaterals as an illustration of learning a geometric concept by moving from the levels of visualization and analysis to the level of formal deduction. The development discusses the classification of quadrilaterals, the inheritance of properties within the hierarchy, connections between algebra and…

For years, College Board has been promoting and publicizing necessary pathways to postsecondary education. Even bolder step is EQUITY 2000--demanding program of prealgebra, algebra, and geometry designed to ensure minority students' success in vigorous high school mathematics programs. Pacesetter initiative aims to make high-standards curriculum,…

Describes the haze-monitoring program that was added to the protocols of the Global Learning and Observations to Benefit the Environment (GLOBE) Program. Finds that sun photometry provides a convenient means for allowing students to perform hands-on science while learning about various topics in history, electronics, algebra, statistics, graphing,…

Reprints an article originally published in 1931. Suggests that the high school of the future will elevate art, music, dramatics, mechanics,and health at least as high as it now (1930) holds Latin, algebra, and chronological history. Suggests that teachers will merge their interests and responsibilities with those of administrators, supervisors,…

The purpose of this study was to find out whether students perform differently on algebra word problems that have certain key context features and entail proportional reasoning, relative to their level of logical reasoning and their degree of field dependence/independence. Field-independent students tend to restructure and break stimuli into parts…

Describes a classroom activity based on the practice of fishermen tying knots in boat anchor ropes to determine river or lake depth. Knot-tying provides a simple hands-on context for students modeling in algebra. Students were actively involved in measuring, collecting data, fitting a line to data, finding an equation for a line, and checking a…

Describes computer or calculator-graphing technology to develop parametric representations which help students connect mathematical topics from algebra and trigonometry through algebraic, graphical, and numerical representations. Computer or calculator graphing utilities instantly transform algebraic expressions into visual and numerical displays…
