A laboratory exercise using a gerbil is described for use in the high school biology class and in accordance with the National Science Teachers Association guidelines. The authors cite references that deal with current awareness of the moral status concerning animals. The exercise includes measurement and calculations. (SA)

This article describes teaching mathematics to students with disabilities using "My Math," a three-component software program consisting of "shells" into which students or teachers insert content. The three components include computation problems, arithmetic word problems, and arithmetic story problems. The content of the program is discussed,…

Proposed is a gradual transition from arithmetic to the idea of an equation with variables in the elementary grades. Vertical and horizontal formats of open sentences, the instructional sequence, vocabulary, and levels of understanding are discussed in this article. (KR)

Outlined is the "nine complements" method of subtraction. This activity was used by students to generate proofs that explained why the subtraction method worked. Reasoning and inquiry skills are emphasized. Other examples are offered that have been successful in stimulating inquiry. (KR)

This article examines the level of understanding by children (six- to seven-year-olds) of the addition and equality symbols. The article reports that about half of the subjects were unable to write the mathematical expression of simple addition while they were able to do it verbally. (YP)

Experiments with 12 sixth-grade students doing mathematics assignments and 9 students doing reading assignments under differing conditions of radio and television distraction indicate no sizable distractor effects on time studying, accuracy of computation or reading comprehension, and reading rate. Results are consistent with the conceptualization…

Offers seven criteria for developing mathematical thinking, plus suggestions for teaching and assessing students' progress that are compatible with each learning criterion. Provides evaluation sheets that help the teacher assess and grade students on the criteria. (10 references) (MDH)

The interaction of reading and computational abilities in solving mathematics word problems was investigated with the responses of about 20,000 fourth graders and 20,000 eighth graders to items from the Iowa Tests of Basic Skills. Item responses exhibited different types of interaction, a finding with implications for item-response theory…

Examined the mathematical beliefs and achievement of 62 elementary school students from a school at which teachers were participating in a project to improve mathematics teaching. Found that students who enjoyed mathematics were also confident of their math abilities and that there was little correlation between parental support and student…

Suggests ways that children's literature can be used to extend mathematical thinking to daily life and events in the preschool and primary grades classroom. Discusses books pertaining to such events as the calendar, celebrating birthdays, the daily schedule, taking attendance, and the lunch menu. (BB)

Forty-eight rural high school students were randomly assigned to groups that solved math problems with paper and pencil or with calculators. Both groups displayed similar attitudes toward math. Results of a word problem test revealed that, after one week, calculator use contributed significantly to mathematical word problem achievement. (LP)

Insights from both cognitive psychology and learning disabilities intervention research are presented to improve understanding of the processes by which number fact fluency develops. Discussion includes assessment guidelines and learning strategies such as counting all, counting on, and alternative groupings. (Author/JDD)

Describes two lessons in which a fifth grade teacher emphasized the mechanics of mathematics, such as carrying out various computational procedures, to her students. The first lesson introduced students to the concept of averages. In the second lesson, the teacher conducted class surveys to provide data for computing averages. (BB)

Presents activities to visually explore the algebraic concepts of variable, constant, the distributive property, and combining like terms. Presents four transparencies that use visual models to understand exercises in students perform the same mental calculations on a number of their choice and obtain the same result. (MDH)

Examined the performance of kindergartners from middle- and low-income families on arithmetic calculations presented in a nonverbal format and in three verbal formats. Children from middle-income families performed better than those from low-income families on verbal calculation tasks but not on the nonverbal task. (BC)
