Recommendations of several publications with regard to the use of hand-held calculators in the mathematics curriculum are presented. Relevant portions of the NACOME and Euclid Conference reports are cited as well as a report to NSF and recommendations from an NIE/NSF conference. Recommendations support expanded use of, and research concerning,…

Investigates students' conceptions and misconceptions relating to the construction of graphs. Qualitative analysis of students' responses identified three main alternative conceptions. Quantitative analyses of the data indicated that overall students did not enter the learning situation as a tabula rasa. Discusses the theoretical and practical…

Investigated middle school mathematics teachers' reports of the effectiveness of various professional development activities influencing their attention to students' thinking. Teacher surveys indicated that teachers' years of experience, views of learning, and mathematics background correlated with their ratings of various activities. (SM)

The experience of several different female mathematicians in the male domain of mathematics is discussed. The implications of the barriers experienced by these mathematicians for girls in mathematics are discussed. (CW)

Demonstrated in this article are some of the capabilities of a spreadsheet program using data obtained in gas law experiments and a computer interface system. The ability to organize and analyze data which a computer can provide for the student is emphasized. (KR)

Presents four examples on arithmetic mean and harmonic mean. Provides solution of each of the examples and instructional activities related to the examples. Lists eight references on mathematical problem solving. (YP)

Presented are four mathematical discoveries made by students on an arithmetical function using the Fibonacci sequence. Discussed is the nature of the role of the teacher in directing the students' discovery activities. (KR)

Investigated how teachers coached one another accepted advice and feedback from colleagues and changes that occurred in classroom practices. Describes and presents data for a peer coaching program. (YP)

Reviewed is an integrated approach to teaching place-value concepts. A semi-integrated approach is proposed which may provide a more effective implementation of the technique. (CW)

A project in which students can develop their understanding of mathematical concepts through the collaborative writing of word problems is discussed. Worksheets for project requirements and daily requirements are provided. A Thanksgiving project is proposed. The use of a fashion modeling problem in the statistics classroom is described. (CW)

Presented is a lesson in which the patterns that occur within and between sequences of polygonal numbers present an opportunity for students to analyze, represent, and generalize relationships. Materials, objectives, levels, and directions for this activity are discussed. Worksheets to accompany the activities are provided. (CW)

Answers several questions asked by teachers about the implementation of the "Curriculum and Evaluation Standards for School Mathematics," including teacher role; textbook change; starting procedures; finding support groups; dealing with feelings; classroom change; and curriculum change. Six references are listed. (YP)

Describes an activity for surveying the mathematical background required for various occupations. The activity is designed to influence students' attitudes toward mathematics. Provides materials and teaching hints for the activity. (YP)

Provides an activity to develop students' (grade 5 through 10) spatial understanding and problem solving ability. Describes materials, prerequisites, directions, extensions, and technology using Geometric Supposer software. Presents worksheets and answers. Four references are listed. (YP)

Describes experiences of developing the "Curriculum and Evaluation Standards for School Mathematics" from the perspectives of three past presidents of the National Council of Teachers of Mathematics. Includes their expectations related to the implementation of the standards. (YP)
