This article describes a project using Design Based Research methodology to ascertain whether a pedagogical task based on a dynamic figure designed in a Dynamic Geometry Software (DGS) program could be instrumental in developing students' geometrical reasoning. A dragging strategy which I have named "Dragging Maintaining Symmetry" (DMS)…

The notion of the lesson "hiccup", defined as the perturbation experienced by a teacher during teaching that has been triggered by the use of mathematical technology, was first proposed in Clark-Wilson. Hiccups which are both unanticipated and unplanned, emerged from a study that sought to make sense of the process of secondary…

In the past decade, researchers have attempted to develop computer-assisted learning and testing systems to help students improve their learning performance. Conventional testing systems simply provide students with a score, and do not offer sufficient information in order to improve their learning performance. It would be of more benefit to…

This paper introduces the language associated with a polygon microworld called Polygon R&D, which has the mathematical crispness of Logo and has the discreteness and simplicity of a Turing machine. In this microworld, polygons serve two purposes: as agents (similar to the turtles in Logo), and as data (landmarks in the plane). Programming the…

In this paper, we present our experiences in using two automatic assessment tools, TRAKLA and TRAKLA2, in a second course of programming. In this course, 500-700 students have been enrolled annually during the period 1993-2004. The tools are specifically designed for assessing algorithm simulation exercises in which students simulate the working…

Describes elements in a course based on formulating principles and basic quantitative hypotheses directly in a programing language, thereby bypassing the language of mathematics. The course is designed to enable mathematically shy students to gain understanding of quantitative methods. Three computer programs are described in detail to illustrate…

Software packages geared to learning disabled college students in such subjects as reading, writing, spelling, and mathematics are briefly described, and a partial list of specialty publishers is included. (Author/CB)

This paper presents a study in a UK university that investigated how first-year (freshman) Information Systems undergraduates perceive learning through courseware containing real-world erroneous examples derived from their peers and what obstacles had to be overcome to implement effective e-Learning support for using and creating such courseware.…

Describes laboratory-oriented software programs that are short, time-saving, eliminate computational errors, and not found in public domain courseware. Program availability for IBM and Apple microcomputers is included. (RT)

The computer is not just a teaching tool, but a teaching medium. Purchase of appropriate software to achieve worthwhile instructional goals is essential. There are several software titles for elementary school educators to consider seriously in mathematics, science, social studies, and language arts. Included is a sampler of effective elementary…

Describes winners of a software awards program developed by EDUCOM and the National Center for Research to Improve Postsecondary Teaching and Learning (NCRIPTAL). Evaluation criteria used to judge software appropriate for undergraduate students in the fields of social sciences, natural sciences, humanities, English composition, mathematics and…

PLATO Learning, Inc., a developer of computer-based instruction, recently released "Math Problem Solving." This product was designed to teach strategies for solving math problems, and consists of 19 problem-solving activities, ranging from basic math to algebra. Each activity includes tools to help find a solution and rule-based coaching to…

This book is designed to provide elementary and middle school teachers with motivating problem-solving activities to use with their students. The text contains interesting and challenging problems from mathematics, language arts, social studies, and natural science which are divided into sections of activities of short, middle, and longer duration…

Notes muMATH is a powerful computer algebra systems assistant for performing symbol manipulation in algebra and calculus. Provides several examples and program listings for calculus tutoring, differentiation drill problems, and integration drill problems. (MVL)

Provides a short BASIC program, RANVAR, which generates random variates for various theoretical probability distributions. The seven variates include: uniform, exponential, normal, binomial, Poisson, Pascal, and triangular. (MVL)
