Analyse à priori, deux possibilités ?
Global comment: |
Review filed on 2010/03/20 21:35 by lobator. |
En première impression, deux utilisations possibles de cette ressource :
- utilisation autonome auprès des élèves, pour aider à "visualiser" le lien entre la représentation graphique et l'expression d'une fonction affine.
- en classe entière (video-projecteur), dans le cadre d'un exercice direct d'application, voire même afin de mettre en place une méthode efficace pour tracer la représentation graphique d'une fonction affine.
| This review is done without a trial in classroom. |

|
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 | |
Comments: L'affichage simultané des coefficients permet à l'élève de visualiser le résultat de ses recherches (et engager éventuellement une résolution par tâtonnement) mais on aurait pu prévoir une mise en évidence des erreurs "classiques" comme l'inversion des deux coefficients par exemple. | ||
| |
|
I know how to set my class for this activity |
|
|
The possible configurations (one computer per student or beamer or personal work) are described | |
|
|
Different roles and phases are described | |
|
|
The exchange of information, for conjectures, validations, conclusions are described | |
|
|
A schedule of the activity is proposed | |
Comments: Aucune mise en oeuvre n'est proposée dans le descriptif de la ressource, ce qui aurait pourtant permis une appropriation plus rapide. | ||
| |
|
I found easily a way to use this activity in my curriculum progression |
|
|
The activity benefits later in the classroom | |
|
|
The activity relates easily with my usual teaching | |
|
|
It helps to understand the mathematical notions at work | |
|
|
The experiments they made provide an introduction to the next topic | |
