Analyzes video recordings of three undergraduate students' textbook-based homework. Focuses on the ways in which their exercise reasoning is mathematically well-founded or superficial. Indicates that most strategy choices and implementations are carried out without considering the intrinsic mathematical properties of the components involved in…

This article reviews social studies instructional approaches for secondary students with mild disabilities, with an emphasis on methods that provide access to the general education curriculum. It highlights research findings on domain-specific instructional approaches for teaching social studies concepts such as historical understanding and…

The use of rules on nonverbal balance scale problems was studied among 5- to 19-year-olds. Latent class analyses indicated that children used rules, that different rules were used by children of different ages, and that both consistent and inconsistent rule use occurred. A model for the development of reasoning about the balance scale task was…

Shows how to find an equation in one variable whose solution set is a given line segment as well as an equation in two variables whose solution set is a given triangle and its interior. (KHR)

Introduces a special triangle for which many different problems can be posed on the basis of one unusual property. Presents three problems and considers different approaches for the first problem. Explores other mathematical problems using the "What if not?" strategy that can be used as classroom activities. (KHR)

Comments on student responses to the three dimensional items produced by first investigating flat paper cutouts of the items. (KHR)

Assesses the contribution of self-regulated learning strategies (SRL), when combined with problem-solving transfer instruction, on 3rd-graders' mathematical problem solving. SRL incorporated goal setting and self-evaluation. Contrasts the effectiveness of transfer plus SRL to the transfer treatment alone and to teacher-designed instruction. SRL…

Examines the phenomenon of dissonant forms of memorizing and repetition from both location and structural perspectives. Attention is drawn to clear evidence that supports, in particular, an argument in favor of gender-response differences in both location and structural dissonance. Also illustrates how the isolation of dissonant response patterns…

Describes a method for teaching Euler's line, the co-linearity of the circumcenter, centroid, and orthocenter of a triangle. Discusses teaching results. (KHR)

Discusses recommendations made by the Expert Panel on Educational Technology, questions how they should be used, and examines the quality of the framework for use as a formative assessment instrument. Considers the focus on schooling and student learning; its use as a national evaluation tool; and its use to develop programs, not just evaluate…

Applies mathematics teaching techniques to the teaching of general problem solving skills for students in all subjects. Offers ways in which every teacher can use these problem-solving techniques in their day-to-day teaching of any subject. Provides a generic framework, rubric, and scoring guide for school-wide use. (Contains five references.) (NB)

Describes an activity for observing sunspots with binoculars and other readily available materials. Introduces students to daylight astronomy. (KHR)

Discusses the importance of observation in science education, how to foster students' observation skills in the classroom, and how to facilitate what they observe when learning. Includes a list of components of good scientific observing. (KHR)

Investigates secondary school students' concepts of isotopes and allotropes and how the concepts are linked to the Periodic Table of Elements (PTE). Questions senior high school students with multiple choice items and interviews. Shows that students actively tried to make sense of what they had experienced. (KHR)

Describes "World Class Tests in Mathematics and Problem-Solving," developed with the belief that creativity is worth nurturing and can be nurtured. (KHR)
