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:…

The objectives of this study are: (a) Evaluate science major freshman students' ability to differentiate between heat energy and temperature, after having studied the topic of thermochemistry; (b) ascertain the degree to which students resist change from the caloric to the kinetic-molecular theory; (c) study the ability to differentiate between…

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)…

In order to examine more closely the ways that children use socially constructed dialogue to mediate task mastery a hierarchical set of computer tasks were presented in an animated game format (ToonTalk) to three adult/child (US Kindergarten) dyads over five sessions. Transcriptions of the adult-child talk were used to determine (1) the types of…

This paper reports on data from seventy-eight 9-11 year old children attending four schools that had participated in a national numeracy initiative in New Zealand. Children's responses to a multi-digit addition problem, including alternative solution strategies, and their ideas about the importance of getting the "right answer" were…

Technology educators are constantly in search of new tools and methods to enhance the education of their students. This article is an excerpt from a longer article published in "The Technology Teacher" that introduced the technology education community to a research- and knowledge-based methodology for design--invention and innovation. This…

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…

Student evaluations from the previous semester start to wend their way back to their recipient faculty members at the beginning of a new term. A college professor finds that introducing the topic of student evaluations early in the semester is more helpful in resolving any problems the students may have than saving up the grievances until the…

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.

"Cognitive Tutor[R]", a full-year course, covers organizing single variable data, simplifying linear expressions, mathematical modeling, solving systems with linear equations, problem-solving using proportional reasoning, and powers and exponents. Students work at their own pace to develop problem-solving skills. The duration of each…

In this study, the researchers examined principal behaviors related with change in school climate. That is, the manner in which principals managed change within their schools and the impact of these change behaviors on the school climate was investigated. Through use of the Leadership Profile (Johnson, 2003) and the Organizational Health Inventory…

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…

Cooperative learning allows individuals with varying abilities to work alongside their peers. Students are placed into achievement levels based on placement test scores. The Regular College Preparatory (RCP) level is a score of 59% or lower and Academic College Preparatory (ACP) level is a score of 60-92% on the placement test. The purpose of this…

This study integrates the purposes of communication, i.e. in-class and on-line discussions, with problem solving skills in the process of learning professional knowledge of pre-service teachers. It attempts to foster both comprehension of professional knowledge and the attitude of contextualizing knowledge with situational factors. More…

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