Dutch researchers investigated the effects of Obuchova's method of teaching measurement to kindergarten children with no knowledge of conservation or seriation. Results indicated training was highly effective. Skills were transferred to conservation tasks not taught in training. Transfer to concepts not included in training was also observed. (SM)

Using R. S. Siegler's retrieval-required task, 19 male and 22 female third graders were examined before they had been introduced to multiplication in school. Examination of error patterns suggests that the basic assumptions of the distribution-of-associations model need to be tested directly and that the retrieval-required task confounds retrieved…

Features an assignment involving average monthly temperatures that can serve as an example of curve-fitting for a periodic function. (WRM)

Explains the strange effect a crosswind has on motion. (WRM)

Proposes that introductory physics courses extend the analysis of one-dimensional motion to a more sophisticated level. Gives four experimental setups and graphical analysis of the distance, velocity, and acceleration in the vertical and horizontal directions. (WRM)

Based on an analysis of student success rates in developmental math courses and the results of a survey of math programs at other community colleges in Virginia, the math faculty at Southwest Virginia Community College increased the number of credit hours for developmental mathematics courses to allow students more time to master fundamental…

Suggests using everyday examples to help students describe the relationships that emerge from the evidence displayed on line graphs during science investigations. (WRM)

Describes a lesson that provides an opportunity for students to obtain the equation for a line describing data they have collected, use the equation they have derived to set up an Egg Bungee Jump, and relate the numbers in the equation to the physical properties of the bungee jump. (WRM)

Introduces a unit on data analysis which would not only satisfy elementary statistics requirements but also involve students in a long-term mathematics project in a meaningful and relevant way. Addresses the mathematical concepts of measurement, graphing, and computation. (ASK)

Presents an activity involving students in the creation of polyhedra which enables them to understand the characteristics and develop a clear definition of different polyhedra for themselves. This activity helps develop spatial ability by encouraging students to experiment with creating models of polyhedra while using a wide variety of polygons…

Presents an activity on probability and area in which students try to decide which door to buy. (ASK)

Describes several activities and games that provide an introduction to the concept of function. Suggests that experiences should depend more on students' experiences and understanding and less on the memorization of unmotivated conventions with abstract symbols. Includes activities for a calculator as a function machine, composite functions, and…

Relates the personal story of how a 13-year-old used previous knowledge of matching words in English to construct her own understanding of mapping in mathematics as it pertains to the National Council of Teachers of Mathematics' (NCTM) recommendation that students use and value connections between mathematics and other disciplines. (AIM)

Discusses the performance of Malaysian secondary school students on a probability concepts test covering various intuitive and taught probability concepts. Describes the establishment of a probability concepts hierarchy and considers probability understanding in relation to independent variables. Boys, Form Six students, and students with a higher…

Describes a model for addressing prerequisite mathematics needs. A small set of prerequisite skills for the content course is identified and assessed, and students needing extra help are assisted. Targeted students include those with only marginal deficits rather than those needing full course remediation. Presents results from empirical testing…
