I explore some facts about the area, position, etc. of the Steiner ellipse using GeoGebra and numerical analysis. Students can use these for mathematical inquiry.

Helping preservice teachers use hybrid language representations in science is important if they are to become scientifically literate and able to engage in the discourse for understanding scientifiyc issues. Using hybrid language representations based on the framework of computer-supported collaborative learning, the teacher educator applied the…

In this paper, we study how prospective teachers guide students' reasoning in GeoGebra-supported inquiry tasks. Twenty prospective mathematics teachers wrote about how they would react as a teacher in hypothetical situations where high school students present their GeoGebra-supported solutions to the teacher. Before writing their reactions, the…

Six preservice social studies teachers created electronic portfolios to examine techniques believed to promote active student engagement during a 12-week field experience. Inquiry into these practices was facilitated through embedded tutorials, assignment suggestions, and question prompts based on principles of evidential reasoning. Although…

This mixed-methods investigation compared the effectiveness of three instructional approaches in achieving desired conceptual change among early childhood preservice teachers (n = 157). Each of the three treatments employed inquiry-based instruction on moon phases using data collected from: (1) the planetarium software program, Starry Night[TM],…

Students are often unable to collect the real-time data necessary for conducting inquiry in science classrooms. Web-based, real-time data could, therefore, offer a promising tool for conducting scientific inquiries within classroom environments. This study used a quasi-experimental research design to investigate the effects of inquiry-based…

This article describes preparation and delivery of high school mathematics lessons that integrate mathematics and astronomy through The Geometer's Sketchpad models, traditional proof, and inquiry-based activities. The lessons were created by a University of Texas UTeach preservice teacher as part of a project-based field experience in which high…

Featuring an increased emphasis on the way today's changing science and technology is shaping our culture, this Second Edition of "Teaching Science in Elementary and Middle School" provides pre- and in-service teachers with an introduction to basic science concepts and methods of science instruction, as well as practical strategies for the…

Describes a software shell, STAR.Legacy, designed to guide attempts to help students learn from case, problem, and project-based learning. STAR.Legacy supports the integration of four types of learning environments: learner-centered, knowledge-centered, assessment-centered, and community-centered. Describes how a STAR.Legacy constructed for an…

Prospective teachers can examine documentary websites known as "snapshots of practice" in an on-line "Gallery of Teaching and Learning" http://gallery.carnegiefoundation.org). Developed by the Carnegie Foundation for the Advancement of Teaching, the Gallery of Teaching and Learning includes a wide variety of web-based "snapshots" developed by…

This qualitative study examined the use of WebQuests as a teaching tool in problem-based elementary methods courses. We explored the potential of WebQuests to address three dilemmas faced in teacher education: (a) modeling instruction that is based on current learning theory and research-based practices, (b) providing preservice teachers with…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
