This monograph offers an overview of the current research work carried out in Croatia and the surrounding countries, and specifically an interesting insight in teaching and learning issues in these countries. The authors discuss the need of the general population for becoming good problem-solvers in society of today, which is characterised by…

In this paper we demonstrate that "lesson study" may be adapted from its primary use as a professional development strategy for use as a research strategy, especially to identify principles of good lesson design. We report on a project undertaken in two Australian secondary schools where lesson study research was used to investigate the…

K-12 teachers lack training in best practices of interactive lesson development. It is essential that teachers utilize interactive whiteboards effectively. Using a collaborative mentor training, this factorial between-within groups study investigated how student achievement was impacted when teachers applied a set of effective interactive…

This paper reports the impact of a collaborative professional experience model on pre-service secondary mathematics teachers' perspectives and practices within a learning community. Nine pre-service teachers made 12 school visits over one year to observe and co-teach problem-solving lessons in two Year 8 classes. They discussed the lesson with the…

Pedagogical maps provide a graphic depiction of the way in which teachers exploit the presence of Computer Algebra Systems (CAS) in their classrooms. They can show differences, and can also show growth, as well as personal preferences and reactions to particular teaching assignments. They might also be used for teachers to reflect on their own…

Discusses simple tools for digitizing objects of interest from image files for treatment in other software such as graph plotters, data-handling software, or graphic calculators. Explores methods using MS Paint, Excel, DigitiseImage and TI Interactive (TII). (Author/NB)

Describes features and uses of the Geometry Forum, a National Science Foundation funded Internet project which includes a set of electronic newsgroups for people interested in geometry. (MKR)

Compares two groups of students in an intermediate algebra course and two groups of students in a college algebra course with regard to the use/non-use of computer algebra software in the courses. Indicates that in both courses, students using the software outperformed the students not using the software on a common final exam. (Author/ASK)

Presents an example of an introductory lesson on spreadsheets which provides a quick overview/revision of the essential elements of spreadsheeting before progressing to programmed exercises. (ASK)

Presents mathematics problems which use technology for exploring and verifying relationships among data sets; comparing and analyzing effects of changes in parameters of mathematical models; simulating complex, expensive, or dangerous events using probability models based on random outcomes; and graphically or numerically zooming in on apparent…

Outlines a geometry task that uses computers to transform some quadrilaterals into other quadrilaterals. (ASK)

Learners' choices of problem solving tools and techniques are influenced by the context in which the problem is encountered, and methods utilized in one context may not be recognized as natural ways to proceed in another. Explores the process of fostering learner-initiated applications of technology to address the wide range of problems outside of…

Advocates of the increasing use of the computer in mathematics teaching and learning claim that certain topics and techniques need no longer be taught. Addresses how far the access to so much computer power should influence the core of mathematics that needs teaching at different levels. (Author/ASK)

In the early stages of working with dynamical geometry environments, students make many more mistakes than if they thought out and implemented the same constructions on paper. Most Czech teachers have very little experience of doing geometry using computers. A methodology which could help them to teach students to avoid mistakes dependent on the…

Describes the use of spreadsheets to discuss mathematical concepts without using algebraic notation. Presents examples using Fibonacci numbers and factorials. (MKR)
