This article presents a didactic situation focused on geometric reasoning using 3D GeoGebra, using the concepts Theory of Didactical Situations (TDS). The objective of this work is to bring a didactic proposal for the teaching of Spatial Geometry, working with the students' geometric perception, oriented and elaborated based on the dialectic of…

This article describes the process used to develop and assess an NSF-funded instructional innovation: an online collection (https://www.CAUSEweb.org/smiles/) of 28 interactive songs of high esthetic quality designed to span literature-based learning objectives of introductory statistics that develop statistical literacy and reasoning. The…

Calculus, perhaps more than other areas of mathematics, has a reputation for being steeped with procedures. In fact, through the years, it has been noticed of many students getting caught in the trap of trying to memorize algorithms and rules without developing associated concept knowledge. Specifically, students often struggle with the…

Dynamic geometry software (DGS) is often used for development of interactive teaching materials in many subjects, not only mathematics. These interactive materials can contain hundreds of elements in order to represent complex objects, and script programs to control their behavior. We propose an approach for creating, importing and using…

Assigning difficulty level indicators to the knowledge units helps the learners plan their learning activities more efficiently. This paper focuses on how to use the topology of a knowledge map to compute and rank the difficulty levels of knowledge units. Firstly, the authors present the hierarchical structure and properties of the knowledge map.…

Many colleges and universities today are faced with the problem of low student academic achievement in math. Some of them are trying to improve student academic achievement through the use of technology. Their proposed solution is to teach children how to use the technological tools available to them and integrate that technology into the…

Students with disabilities and special needs have faced challenges in accessing educational content, and in taking traditional pen-and-paper tests. How might technology improve the process, while making statewide tests truly accessible to all students? NimbleTools is the first computer-based test delivery system that incorporates principles of…

Because a significant portion of U.S. students lacks critical mathematic skills, schools across the country are investing heavily in computerized curriculums as a way to enhance education output, even though there is surprisingly little evidence that they actually improve student achievement. In this paper we present results from a randomized…

Ways to use data base software to develop conceptual understanding are presented. Discussed are the concepts of a data base, setting up the data, and an assessment of learning with examples. Six references and four journal resources are listed. (YP)

Describes the use of spreadsheets. Presents four examples using a pre-designed format: repaying a loan, investigating functions, exponentials, and Fibonacci numbers. Provides three practice problems. (YP)

Discusses the use of courseware designed to prepare high school students for the Scholastic Aptitude Test (SAT). Provides a review of six software packages specifically designed for this purpose. Discusses, as an alternative, a non-computer plan for SAT preparation. (TW)

Describes a study that provided innercity fourth grade African-American students in Texas with hardware to participate in a telecommunications network to determine whether participation would increase their scores on statewide fifth grade math tests. Time online, content of programs, connections between math and language arts, and student…
