Thinklets and TI; Technology for Learning and Doing Mathematics Martin van Reeuwijk Freudenthal Institute Utrecht University, Netherlands
RME technology examples the future …
Freudenthal Institute (FI) • Research and Development of Mathematics Education • Research institute at Utrecht University • About 30 fulltime positions actually working about 50 staff members
Core activities of the FI • Macro- and micro-didactic research; • Curriculum development; • Assessment development, comparative achievement studies (e. g. PISA); • Research on and development of educational technology (ICT); • Professional development and teacher education (bildung); • Organization of and participation in national and international networks, conferences
Features and Focus • Primary, secondary, and vocational education • national and international projects • Integrating research, development and teacher education activities • Working for and with teachers: journals, conferences, courses, websites • Philosophy/theory: Realistic Mathematics Education (RME) • Methodology: Developmental Research back

Realistic Mathematics Education a short introduction …
Realistic Mathematics Education in short Start with a context.
Realistic Mathematics Education in short 4 24 Breaking leads to fractions …
Realistic Mathematics Education in short 2 4 24 + 24 Chocolate pieces become model for fractions …
Realistic Mathematics Education in short 1 4 3 4 Rectangle model for operating with fractions …
Realistic Mathematics Education in short Vertical mathematization Formal mathematics, abstract, Model for, pre-formal, Model of, informal, intuitive Guided reinvention Horizontal mathematization Contexts, problem situations, concrete, realistic Solving problems
Characteristics of RME • • • Starting in contexts Building on preformal knowledge Different strategies and answers ‘Guided reinvention’ From “model of” to model for” Horizontal & vertical mathematization Intertwining learning strands Practical value Meaningful and sense making back
Technology in Mathematics Education • different kinds • different purposes
Technology in Mathematics Education • • • Tools Models Games For Practice For concept development For testing, assessment • Learning Environment
Technology in Mathematics Education Tools n Graphing, solving, calculating • Graphing calculator n APPS (applications), TI Navigator (network of calculators) n Real data collection (sensors) (e. g. Easy. Data for real measurements) • Thinklets n On-line web based, user friendly n Many variations possible

Mathematics as an human activity; learning and doing …thinklets • Building houses
Thinklets What are Thinklets • small computer programs that run over the internet (aka applets) • can make learning mathematics more fun, more sense making, and more efficient. • Easy, simple to use, user friendly • Interactive, visual, dynamic • Fit a mathematical topic • Tested in class and improved
Thinklets Easy, small, feedback • Frog • Solving Equations
Thinklets Use of Thinklets • Supporting instructional materials can be used, on screen or paper (worksheets) • Used in various moment in the teachinglearning process: exploration, a tool, concept development (model), practice, assessment, . . .
Thinklets One or many Thinklets … • Algebra arrows
Thinklets Add-on value of thinklets • Fun and motivate students • Work at own level of thinking, possible to address differences between students • Visual, interactive, dynamic • Focus on concept and model, applet does calculations • Promotes creativity and self esteem • Provides a model students can fall back on • Feedback and practice are powerful • Webbased: Always and everywhere available back
a Future of Technology in Mathematics Education • (actual) conditions • future device
Future of technology in mathematics education The conditions • Continuous development and research • Alternatives for (commercial) publishers paper with textbook series are becoming available • Students want to move faster than teacher and textbook, generation gap • Hardware (Internet connection) is no problem any more, always available • Still transition to ICT-integrated math ed is hard
Future of technology in mathematics education The challenge … (for TI, Casio, …) is to develop a device that is: Handheld, easy to use On-line, web based Tool and model Multi purpose (reference guide, calculator, word processor, PDA, browser, phone, music player, camera, …) • For fun (games) and school (also fun) • •
