Investigates students' use of imagery in their mathematical activities. Findings indicate that image forming is crucial in doing mathematics. A student who fails to construct an image in a problem-solving situation is severely limited in giving meaning to the situation. Contains 21 references. (JRH)

"Give an example" tasks invite students to consider mathematical concepts in relation to their properties according to the data collected by interviews and a questionnaire asking students' strategies for generating the example. Examines how these tasks contribute to the construction of links which in turn lead to construction of more webbed and…

Discusses overall mental computation achievement and limits discussion to strategies middle school students used when computing with whole numbers, decimals, and fractions. Suggests that the development of conceptual knowledge of numbers is an important prerequisite for the understanding of mental computation procedures. (Contains 31 references.)…

Discusses a case study in which the cognitive monitoring moves of a pair of preservice elementary education teachers were examined during cooperative problem-solving tasks. Concludes that assuming different roles during the problem-solving experience can be an effective strategy and a potentially helpful learning experience. (31 references) (MDH)

The difficulties and misconceptions that many students experience when learning to visualize graphs of functions are discussed. Specifically, the inability to make accurate connections between symbolic and graphical representations, the lack of understanding about scale and scaling, and the confusion caused by transformations are examined with…

Describes how a mathematics teacher's knowledge level can be supported or justified by a criterion different from test scores of teacher's students, namely the ability of the teacher to justify teaching practices by appealing to concurrent learning method. Two examples are provided that formalize theoretical justifications as practical arguments…

Challenged is the traditional model for the transmission of mathematics in the elementary school classroom. An inquiry approach to learning mathematics is proposed and supported with results of a year long research project that exposed second graders to mathematical learning experiences using this approach. (MDH)

Illustrates and discusses one class of strategies to solve word problems referred to as "number-consideration strategies." Contrasts actions and goals of students who focus mainly on number considerations with those of students who focus mainly on problem understanding. (MDH)

Presents a study that indicates that second grade students (n=117) do select manipulatives that match the story context in measurement and partition division word problems, that they can solve division word problems, especially when matched manipulatives are used, and that division without remainders are more accessible to solution.
