Ten high-ability middle school students participated in a 13 week enrichment program on inferential statistics. Consistent with the NCTM Standards, classes emphasized problem solving in real world contexts and the communication of mathematical ideas. Students struggled with written assignments, yet worked effectively in pairs, small groups, and…

Of all the reform recommendations being made by the National Council of Teachers of Mathematics, making mathematical connections is among the more difficult to achieve, especially at the high school level, where so much emphasis is placed on distinct content courses. Mathematical connections can relate mathematical topics to students' daily lives…

This paper describes mathematical modeling activities from a secondary mathematics teacher education course taken by fourth-year university students. Experiences with mathematical modeling are viewed as important in helping teachers develop a more intuitive understanding of mathematics, generate and evaluate mathematical interpretations, and…

Kanawha County (West Virginia) schools use Z-scores to identify elementary students eligible for Chapter 1 services in reading and mathematics. A probit analysis of over 500 previously served students was used to determine the variables and weights in the Z-score equations. Independent variables were chosen from those commonly used to identify…

This paper discusses the poor preparation of children with disabilities in math and science fields, and the perception that students with disabilities are not capable of doing work in science and math, which is often reinforced by teachers and parents. It is argued that the low expectations and waived requirements for children with disabilities…

This yearbook explores the relationship between elementary school technology education (ESTE) and the traditional subjects of the curriculum, reports on methods of ESTE implementation, and describes roles of teacher preparation and inservice professional development activities for promoting ESTE. Contents include an introductory chapter; 11…

Evaluators usually assume that the data they receive are valid, or at least, that the data reflect that which is being evaluated. In a recent evaluation in a large southern school district, evaluators compared their raw interview notes with interview notes edited by the teachers interviewed or project staff. The program evaluated was Project SEED,…
