The uses of programable calculators in the mathematics classroom are presented. A discussion of the "microelectronics revolution" that has brought programable calculators into our society is also included. Pointed out is that the logical or mental processes used to program the programable calculator are identical to those used to program…

This study investigated the effects of the use of hand-held calculators on problem solving and computational skills of elementary school students. It also considers the resulting implications for curriculum change. Evaluation focused on achievement in problem solving, computational skills, and number concepts of kindergarten, second grade, and…

This USMES unit challenges students to find a good way for them to tell many people about any topic or problem of the students' choice. The teacher resource book for the Mass Communications unit contains five sections. The first section describes the USMES approach to student-initiated investigations of real problems, including a discussion of the…

This USMES unit challenges students to find the best way to advertise a product or an idea that they want to promote. The teacher resource book for the Advertising unit contains five sections. The first section describes the USMES approach to student-initiated investigations of real problems, including a discussion of the nature of the USMES…

The term "numeracy" is used in the adult education community to include an array of mathematically related proficiencies that are evident in adults' lives and worthy of attention in adult education settings. This occasional paper attempts to describe the complex nature of numeracy as it exists today. All stakeholders--including policymakers,…

While the influence of individuals' participation in practices of economic subsistence on the development of mathematical knowledge has been widely reported in the literature, there are not as many studies about the relationship between cultural life and mathematical cognition in the context of recreational practices. This article reports a study…

No longer just a user of commercial software, the 21st century teacher is a designer of interactive software based on theories of learning. This software, a comprehensive study of straightline equations, enhances conceptual understanding, sketching, graphic interpretive and word problem solving skills as well as making connections to real-life and…

The framework of the new British Columbia mathematics curriculum for grades 1-7 includes willingness to take risks and expanded tolerance of ambiguity as goals of mathematics learning. Two projects in Victoria (British Columbia) elementary schools explored ways to promote positive student attitudes toward mathematical tasks and problem solving.…

Noting that assumptions about the teaching and learning of early childhood mathematics have changed substantially since the 1970s, this chapter examines recent research that may inform curriculum development in early childhood mathematics. The chapter begins with a consideration of the theoretical perspectives for defining an appropriate…

Describes a mathematical investigation centered on collecting and analyzing data in a scientific setting. The first experiment teaches the basics of data collection--students should be able to identify variables that might have affected experimental results. The second activity includes designing an experiment to control for these variables. The…

Presents an extended activity consisting of a sequence of tasks organized so that students can visit several mathematical concepts concurrently and explore connections among them. Students build solids using bendable straws to form the skeletons of various polyhedra. Topics covered include tables and charts, algebraic expressions, surface area,…

Describes the use of the Internet to investigate mathematical problems, create and share information, discover patterns and relationships, and find out more about the world. This unit investigates pet ownership and introduces children to telecommunications, the use of the computer as a tool, and scientific research methods. Other units address…

Presents a curriculum unit designed for average sixth-grade students intended to engage them in problem-solving experiences and to teach them problem-solving strategies. The curriculum consists of 20 sessions in which students engage in various activities using the following software packages: The Adventures of Jasper Woodbury, Rescue at Boone's…

Four means of assessing student learning that are used more and more frequently in mathematics classrooms include group and individual problem-solving exams, group projects, written reflections, and self-assessment. The article describes the use of the four elements in one mathematics content course for elementary education majors. (SM)

Investigates issues of conceptual understanding in teaching and learning mathematics provided conceptually based instruction on place value and two-digit addition and subtraction without regrouping in four first grade classrooms. Conventional textbook-based instruction was provided in two first grade classrooms. Experimental-group students scored…
