Presents results of 46 randomly selected children's performance measurement and partitive division problems when remainders are zero, nonzero but not used in the solution, and nonzero and used in the solution. Results indicate that children demonstrate an understanding of division prior to formal instruction. (MDH)

The third in a series of 3 articles, a study of 30 students was conducted to test the effect of restructuring a unit on trigonometric identities around microcomputer activities based on the themes of educational undercurrents identified in Part II. Experimental-group students scored significantly higher relating trigonometric functions to their…

Focuses on the language used in mathematics instruction and the ways in which teachers assist students in constructing the formal language of mathematics. Strategies to help students connect vocabulary with mathematical concepts include using teacher modeling, writing, cooperative learning, and having students define words in their own language.…

Children's (n=70) solution strategies to a variety of multiplication and division word problems were analyzed to determine performance levels and strategies used. Solution strategies were classified at three levels: direct modeling with counting; no direct modeling with counting, additive, or subtractive strategies; and use of known derived facts.…

Describes four activities to develop visualization skills and the concept of dimensionality in which students (1) visualize transforming figures between the second and third dimensions; (2) identify the three-dimensional objects from their two-dimensional projections; (3) conjecture about the vertices, edges, and faces of zero- to four-dimensional…

Describes an extra credit science project in which students compete to see who can build the most efficient water rocket out of a two-liter pop bottle. Provides instructions on how to build a demonstration rocket and launching pad. (MDH)

Presented are four activities that focus on gathering and interpreting data about pizza as a basis for integrating mathematics, health, and social studies. Reproducible sheets for parents to use with their children, class-activity sheets, and a data sheet are provided. Each activity includes the objective, needed materials, directions, extensions,…

A project in which teams of preservice teachers were grouped with teams of seventh grade students and worked cooperatively on a set of assignments is described. The plan, project, implementation, results, and summary are presented. (KR)

Stresses the importance of metacognitive skills (knowledge of one's own cognitive processes) in mathematical performance. Discusses the differences between metacognitive thinking and metacognitive experiences and the ways they each influence performance. Describes how accurate metacognition improves students' mathematical performance, and outlines…

Addresses problems with mathematics and science curricula at both elementary and secondary levels, and calls for helping more students succeed at the physics level of the science curriculum. (PVD)

Describes the design of a hypermedia tool for helping preservice teachers learn about the growth and development of children's mathematical reasoning based on research in cognitive science, and discusses results of an experiment that used single-subject methodology to compare preservice teachers' learning with the hypermedia tool versus learning…

Examined the perceptions of preservice elementary teachers enrolled in reading, mathematics, and integrating reading and mathematics methods courses about integrating mathematics, reading, and writing instruction at the elementary/middle school level. Surveys indicated that all students were generally positive about instructional integration. They…

Fourth, sixth, and eighth graders and adults estimated answers to multiplication problems and explained their estimation procedures. Found performance improved with age, and sixth graders understood the simplification principle in estimation. The most striking developmental changes were in conceptual knowledge used for estimating. Proposes a…

Investigated the percentage of high school seniors reporting intentions to major in education and actually majoring in education over 2 years, examining high school academic proficiency levels and the impact of type of college attended (2-year or 4-year). Less than half the students majored in education. There were differences by high school…

Like so many other states, Iowa faces the acute challenge of improving teacher quality. To address this problem, the state has been conducting and procuring a system over the last two years that will move Iowa into compliance with No Child Left Behind Act (NCLB) requirements in the areas of teacher quality and the core subjects of reading,…
