Mass Production of Theorems in Solid Geometry

Before Cabri 3D came to existence, Solid Geometry was treated just like any other theorectical science and very little could be experimented. After Cabri 3D was released, Solid Geometry gradually became an experimental science! We shall explore in this workshop how two types of plane geometric results can be directly converted into theorems in 3D: those involving circles only and those involving straight lines only. Laboratory setup: Cabri 3D with Internet connection. Hardware requirement: graphic card with 256K of memory.

Let's Develop Interactive e-Textbook for Classroom: Your Innovation by Freeware ''dbook''

In any countries, teacher and students use textbooks for teaching and studying mathematics even if they do not use the software or calculator. Now, a number of schools in many countries equipped projectors as well as Blackboard. Interactive board is also good equipment. On this demand, the software ''dbook'' was developed by Masami Isoda, CRICED, University of Tsukuba. It aimed for editing eTextbook from ordinary printed materials such as students’ textbooks, distributing it through the web and using it with projector. ''dbook'' supports free Dynamic Geometry Software (DGS) by GCL (Geometric Construction Language) and flv video format. Now, we are preparing to support graphing. If you use dbook, you can use DGS and Graphing tool on your textbook by free. This workshop provides you how to develop eTextbook from ordinal printed textbook with DGS. http://math-info.criced.tsukuba.ac.jp/software/dbook/dbook_eng/

SPICE UP YOUR LESSONS WITH ANIMATED MATHS MAGIC AND PUZZLES!

Getting students excited about learning is the teachers’ constant challenge. The answer lies in incorporating creative techniques into our classroom practice. Spicing up our lessons with some mathematical magic and puzzles could easily help increase attention, understanding and retention significantly. Appropriate recreational problems stimulate intellectual curiosity, develop problem solving skills, promote discovery and thinking skills, as well as unleash creativity. In this workshop participants will be participating in deciphering some interesting mathematical magic and puzzles (using Flash programming). These problems appear to be recreational or magical in nature but they are actually based on sound mathematical concepts. In solving these problems, students actively participate in discovering or deciphering the hidden principles underlying each problem and in the process construct their own knowledge of mathematics. This presentation also stress on the need for excitement to encourage mathematical thinking. Mathematical magic can serve as an effective means of motivation at almost all levels of instruction. The major purpose of its use in the classroom is to enable students to discover that mathematics is easy and interesting, and thus stimulate interest in their further study of mathematics. Target audience: Upper primary and lower secondary schools mathematics teachers as well as teacher trainers

FATHOM-2 Based Mindware for Developing Inferential Reasoning in Statistics

Students learning statistics at the university level usually learn formal inferential statistics to enable them to make inference about the population from data collected from a sample. However, a number of students have difficulty understanding the reasoning underlying the statistical inference process. Students do not understand the importance of ideas such as resampling, sampling distribution and hypothesis testing used in inferential statistics. In this workshop students will undergo through a mindware which consist of two tasks that will provide them with opportunities to experience informally ideas like resampling, sampling distribution and hypothesis testing through the use of a dynamic statistical software known as Fathom2.

The educational use of scientific calculators

Over the last four decades scientific calculators have been used for calculations in trigonometry, for handling logarithmic and exponential functions and for simple and more complicated arithmetic calculations. More recently, modern scientific calculators have been developed more widely to extend the mathematical capabilities to equations, vectors, matrices, complex numbers, probability and statistics, as well as elementary calculus operations of integration and differentiation. In this workshop suitable examples will be used to consider ways that fairly sophisticated mathematical and statistical concepts can be developed, with the use of these modern scientific calculators. We will use the Casio fx-570 series of calculators, but do not expect that participants will have prior experience with these calculators.
