Animation d'un triangle et les mesures de ces angles
Global comment: |
Review filed on 2009/03/07 16:08 by Digeon?. |
Figure pour conjecturer la somme des mesures des angles d'un triangle.
Ne sers pas pour la démonstration.
Les préférences des mesures des angles sont inappropriées.

Translation of the mathematical activity into interactive geometry is coherent |
|
|
The math and the figures are related | |
|
|
The figure is behaving consistently within the activity | |
|
|
The figure shows no ill effect | |
|
|
The numerical values (angles, lengths) are consistent | |
|
|
Functionalities and specific behaviors like sliders, keyboard interaction or macros are well described | |

|
In this resource, Interactive Geometry adds value to the learning experience |
|
|
I can produce drawings which are clear and sharp | |
|
|
Different configurations are easily produced | |
|
|
Helps the user to explore, experiment and conjecture | |
|
|
Conjectures can be visually validated | |
|
|
Different representations can be compared | |
|
|
Leads to understand geometric relations rather than numerical values | |
|
|
The activity can not be transposed to paper and pen | |
|
|
Interactive geometry helps reaching the pedagogical goal | |
|
|
Dragging around, you can illustrate, identify or conjecture invariant properties | |
|
|
Dragging around, you infer dependency relations among objects | |

This activity helps me teach mathematics |
|
|
The students (will) get readily to the point | |
|
|
Hints are given on ways to make the students start | |
|
|
Students initiatives are fostered | |
|
|
Some reports and students snapshots help me foresee the situations that arise | |
|
|
I am helped in identifying resolution strategies, whether correct or invalid, that the students may choose | |
|
|
The feedbacks from the software are discussed and actions to use them are proposed | |
|
|
The feedbacks help the students reach understanding | |
|
|
Remedial actions with respect to expected dead-ends are described | |
|
|
Actions to help the students change strategies are proposed | |
|
|
Advice to determine how and when to synthesize findings is given | |
|
|
How, when and who validates the conclusions are described | |
|
|
The overall activity and what takes place, what are the expected benefits and other possibilities are described | |
