for this experiment we ran it twice with slight changes in between. We have 3 classes :

Our population

Pre-test conceptions per group:

Post-test conceptions per group:

“Learning Gain” per group:

pretest = na.omit(subset(tmp2, user_data$test == "pretest"))
posttest = na.omit(subset(tmp2, user_data$test == "posttest"))

Tests

Activity 1

In this activity the child uses the robot to feel the shape. He hypothesis where will be its symmetrie and checks using the robot.

Activity 2

In this activity children manipulate the symmetry axis (robot blue and orange) and observe the effects on the symmetry of the segment (green robots)

Activity 3

Here children observe the symmetry of 3 points. The points are in the two sides of the symmetry axis.

Activity 2 bis

In this activity children manipulate the symmetry axis (robot blue and orange) and hypothesize on the position of the symmetry of the segment (green robots). The check by using the robot (haptic feedback)

Relance

The Number of relance per group and per activity:

Intervention

The number of intervention per group and per activity

Haptics

Activity 1: Here the goal was to find the symetry using haptic and visual feedback.

Activity 2 bis (Cully 7H only)
