The main example of a supposer is the Geometric Supposer, which does not have draggable objects, but allows students to study pre-defined shapes. Nearly all of the following programs are DGEs. For a related, comparative physical example of these algorithms, see Lenart Sphere.
While teachers often choose to use educational software from other categories in their IT suites (e.g. reference works, children's software), a whole category of educational software has grown up specifically intended to assist classroom teaching. 'Wordshark', for example, was first released in the mid nineties with multi-sensory games to ...
The color wheel was designed to allow teachers to demonstrate how colors mixed and worked together. The wheel was based on the Maxwell Disk, [1]: p. 20, 34 a simple tool created by cutting a radial split in two or more colored disks and joining them. By doing so, colors could be mixed by rotating the disks to show a different proportion of each ...
This is a list of software palettes used by computers. Systems that use a 4-bit or 8-bit pixel depth can display up to 16 or 256 colors simultaneously. Many personal computers in the early 1990s displayed at most 256 different colors, freely selected by software (either by the user or by a program) from their wider hardware's RGB color palette.
Fauve Matisse (later Macromedia xRes) was a pioneering program of the early 1990s, notably introducing layers in customer software. [5] Currently Adobe Photoshop is one of the most used and best-known graphics programs in the Americas, having created more custom hardware solutions in the early 1990s, but was initially subject to various litigation.
For example, many teachers set up reward programs in their classrooms which allow students to earn free time, school supplies or treats for finishing homework or following classroom rules. [ 4 ] Teaching machines with gamification features were developed by cyberneticist Gordon Pask from 1956 onwards, after he was granted a patent for an ...
Games lacking support for 256-color graphics were forced to fall back to four-color CGA mode (or not run at all) due to the incompatibility with EGA video modes (320 × 200, 640 × 200, or 640 × 350, all in 16 colors). Some games, including point-and-click adventures from Sierra On-line and Lucasfilm Games, as well as simulation and strategy ...
