This study focuses on the constructions in terms of area and perimeter in equivalent triangles developed by students aged 12-15 years-old, using the tools provided by Cabri-Geometry II [Labore (1990). "Cabri-Geometry (software)," Universite de Grenoble]. Twenty-five students participated in a learning experiment where they were asked to construct:…

This article synthesizes findings from previous research on instructional interventions in mathematics for students with emotional and behavioral disorders (EBD). A systematic search of the literature from 1985 through December 2005 yielded 13 studies that met the criteria for inclusion in this review. The review yielded several findings: (a)…

This study explores pupils' performance and processes in tasks involving equations and inequalities of complex numbers requiring conversions from a geometric representation to an algebraic representation and conversions in the reverse direction, and also in complex numbers problem solving. Data were collected from 95 pupils of the final grade from…

Teacher should strive to be more than the authority in the classroom identifying right versus wrong relating to problem solving. Identifying and emphasizing what aspects of an answer are mathematically correct improves students' confidence to tackle challenging problems and they view themselves as mathematical problem solvers.

The OEYP state-funded program provides extended learning for students who are at risk of academic failure. This report summarizes Austin Independent School District's OEYP activities during 2008-2009.

This study was conducted to examine the promising practice of using technology in teaching math and science in a charter high school in California. The research employed an in-depth qualitative case study method. The main participants were principals, lead teachers, teachers, and support staff. Interviews, observations, and archival documents were…

This report summarizes Austin Independent School District's state-funded optional extended year program for the 2007-2008 school year.

This paper discusses the use of process writing to assist middle and junior high school students in becoming competent, confident mathematical problem solvers and communicators. The process writing technique involves students in four recursive, overlapping stages in writing: rehearsing, drafting, responding, and revising. Students utilize this…

This paper presents a research study of children using on-screen manipulatives (objects represented graphically on the computer screen) in learning mathematics. The paper begins by offering the rationale for the use of manipulatives in mathematics education, an assessment of why manipulatives are not more commonly used in schools, and a discussion…

Determining which brand of a product is the best buy for a specific use is the challenge of this Unified Sciences and Mathematics for Elementary Schools (USMES) unit. The challenge is general enough to apply to many problem-solving situations in mathematics, science, social science, and language arts at any elementary school level (grades 1-8).…

This Unified Sciences and Mathematics for Elementary Schools (USMES) unit challenges students to find ways to help themselves and/or others adapt to new situations (including school and community facilities). The challenge is general enough to apply to many problem-solving situations in mathematics, science, social science, and language arts at…

This Unified Sciences and Mathematics for Elementary Schools (USMES) unit challenges students to improve the safety and convenience of a pedestrian crossing near a school. The challenge is general enough to apply to many problem-solving situations in mathematics, science, social science, and language arts at any elementary school level (grades…

In this set of four booklets on collecting data, primary grade students learn how to record data, do an experiment, make an opinion survey, and choose a sample. The major emphasis in all Unified Sciences and Mathematics for Elementary Schools (USMES) units is on open-ended, long-range investigations of real problems. In most instances students…

In this set of six booklets on collecting data, intermediate grade students learn how to collect good data, round off and record data, do an experiment, make an opinion survey, and choose a sample. The major emphasis in all Unified Sciences and Mathematics for Elementary Schools (USMES) units is on open-ended, long-range investigations of real…

This conference proceedings contains three plenary session reports, 12 working group and 79 research reports, 35 short oral reports, 60 poster session reports, and two discussion group reports. The titles of all papers (excluding "short orals", "posters", and brief discussion group reports) are: (1) "On Relationships…
