The NCTM Research Committee developed this article to address a distinctly important activity that links research and practice: writing research-based articles for practitioner journals. Six guiding principles are described. (Contains 6 figures.)

Three "JRME" authors describe the process of publishing their research in "JRME". All 3 authors published parts of their dissertation in "JRME" and are sharing their stories to help (new) researchers in mathematics education better understand the process and to offer (experienced) researchers in mathematics education a tool that can be used to…

This supplement contains the annual listing of research in mathematics education for 1994. Chapter 1, "Dissertation Research Reported in 1994" (Michael L. Bumbaugh & Sigrid Wagner), lists 251 dissertations abstracted in Dissertation Abstracts International during 1994 along with an index of dissertations by institution. Chapter 2,…

Concrete problems were significantly less difficult than abstract problems at both junior and senior high school levels, as previously observed at elementary school level. Factual problems were significantly less difficult than hypothetical problems at junior and senior high school levels, in contrast to elementary school results. (MNS)

Investigated were the effects of spatial training on calculus achievement, spatial visualization ability, and the use of visualization in solving problems on solids of revolution. Sex differences were found favoring women in calculus achievement and men in spatial visualization ability. (MNS)

Women from five Canadian universities overestimated their final grades less often and underestimated them more often than men did. No sex-related difference was found in level of confidence to complete the bachelor's program, but women expressed less confidence in their ability to obtain the doctorate. (MNS)

For an entire school year, 24 seventh-grade classes were taught problem-solving strategies; in 14 of these classes the instruction was supplemented by calculators. Mixed findings resulted for both problem solving and calculator use. (MNS)

Eleven retarded children with mental ages (MA) less than 4.5 years were examined to evaluate whether there is a critical MA for learning basic counting principles and how an understanding of counting develops. Results are discussed in terms of individual needs. (MNS)

Sixteen Brazilian third graders aged 8-13 were given problems involving multidigit computation. School-taught algorithms were likely to be used in school-taught problems, with little carry-over to real problem situations, but resulted in more incorrect answers. (MNS)

A content-oriented analysis of written solutions to test items in Israeli high school graduation examinations in mathematics yielded six error categories: misused data; misinterpreted language; logically invalid inference; distorted theorem or definition; unverified solution; and technical error. (Authors/MNS)

Kindergartners appeared to differ in their readiness to use a concrete counting strategy for addition. Many persisted in counting with objects. Mental counting strategies were sequenced. (MNS)

Senior-year mathematics test scores are highly dependent on the number of mathematics courses taken at the level of Algebra I or above. Sophomore students with similar levels of mathematics achievement may be expected to improve similarly regardless of race or sex by taking additional mathematics courses. (MNS)

Four methods of solutions and 12 calculative strategies were found from introspective reports of 15 skilled and 15 unskilled students in grades 11 and 12 doing mental multiplication. Unskilled students used strategies more suited to written than mental computation, while skilled students used strategies based on number properties. (MNS)

The effects of two instructional strategies for sequencing examples and nonexamples of the concept "parallelogram" were compared for sixth graders. A rational sequence was favored over a random sequence at the formal level of concept attainment; no interaction effect was found between the strategy and students' mathematical ability. (MNS)

Students at concrete or formal operational reasoning levels made similarity judgments on geometric concepts and mathematical expressions on ratio, proportion, and similarity. Clear prototypical maps could be derived for both groups. Formal operational students structured subject matter content significantly more like subject matter experts than…
