Transformable Pictures
* Engage students in learning by letting them import and transform any image.
* Import digital photographs or drag and drop images from a web page into a sketch.
* Pictures can be reflected, rotated, dilated, attached to points, cropped to polygons, iterated, used in locus constructions, and more!

Hot Text™
* Hot Text makes presentations clearer and more effective by dynamically linking captions and the objects they describe,
* Simply click an object to insert its fully mathematically formatted notation (Hot Text) into a caption.
* Mouse over that Hot Text to highlight the referenced object.
* We've also added numerous text-editing shortcuts and enhanced keyboard input of mathematical expressions, including pi and theta.

Marker Tool
* The Marker tool enhances presentations and facilitates the use of interactive whiteboards.
* Add clarity with angle markers, congruency marks, and parallel arrows.
* In blank space, you can handwrite text or circle parts of your sketch for emphasis or make a freehand drawing that you can then transform.

Expanded Algebraic Capabilities
* Function plots and loci can be transformed and iterated, and intersections of function plots can be found.
* Construct entire families of functions and families of curves, parameterized either geometrically or numerically.
* Choose a grid with trigonometric labels, create and listen to dynamic audible functions, and graph parametric functions.

Expanded Geometric Capabilities
* Easily construct polygons and their interiors with the new Polygon tool.
* Angles can be defined by two intersecting rays or segments, and can also be defined to be reflex angles greater than 180° or trigonometric angles (between –2π and 2π radians).
* Multiple transformations can be combined into a single custom transformation.
* New nonlinear transformations can be defined and added to the Transform menu.

Improved Display
* Expanded line weights, line strokes, point sizes allow for age-appropriate sizing of objects.
* Text style and size on axis tick marks are adjustable.
* Mathematical italicization is used in labels, measurements, calculations, and equations.
* The layout of mathematical expressions is improved — you can use Greek symbols, multiple or nested subscripts in labels, and other mathematical notation.

Integrated Support and Curriculum
* The Learning Center provides guided step-by-step tutorials with embedded videos and a library of student-friendly tips in comics and videos.
* You'll also get access to a wide array of resources including classroom-ready activities for students from elementary through high school.
* The online Reference Center has also been improved.
* Direct support for students using Sketchpad LessonLink has been integrated.

Performance and Usability
* All your Version 4 sketches and activities will still work — they'll just work faster.
* Sketchpad Version 5 supports Unicode and video game-quality graphics through a tenfold increase in data compression, high-performance graphics acceleration, and advanced data handling.
* The new Information tool gives quick access to definitions and properties of objects.
* New JavaSketchpad applets can incorporate algebraic functionality and action buttons.作者: namtran 时间: 2009-6-29 22:48
