Situating tool

Situating tool
The computer serves as situating tool. we can locate lots of simulations and games which can enhance learning. Simulations are mostly used while teaching science. by means of virtual reality extension systems. the computer creates 3-D images on display to give the user feeling that is situated in a virtual environment.

situating tool is similar to constructive tool in that it also allows users to manipulate variables in the system. however the focus of situating tool is not so much on the manipulation of variables, but more on situating students in an environment for certain instructional purposes (eg. experiencing the different culture under the same dzongkhag).

For this reason, if a focus is on learning the relationship between the two variables, a simulation program can be a constructive tool. But it can also be a situating tool if the focus of instruction is on experiencing the context of an environment.

Integration in lesson 
situating tool is useful when it is impossible or difficult to attain real-life experience.  For example, in order to teach how the Merak-Sakteng culture is different from other parts of a country, the teacher may set a trip and let students feel and experience the real culture of the Merak-Sakteng. so in this way, students will learn better.

Misuse 
Expose students to a system which stimulates an environment in real life and which can be easily attained

Concept: Rectangle is a plane with four sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.  

Situating tool using Geogebra:  Constructing rectangle

Procedures:

Step by Step to construct right angle triangle in Geogebra

1.       First click on Geogebra icon from desktop

2.      Draw two points A and B using the New Point tool

3.      Draw the line segment AB and CD using the Segment between

4.  From A draw a circle through B, from B draw a circle through A and from C draw a circle through A, from D through B using the Circle with Centre through a Point tool. Join line from A to C and B to D.

5.      Hide the circles by right-clicking them and deselecting Show Object.
