Connected Mathematics: ProbLab |
[ Home ] [ Overview ] [ Publications ] [ Research Sites ] [ Models ] |
The ProbLab models and construction activities provide contexts for learning central concepts of probability and statistics.
Students explore the models, guided by structured experiments and riddles.
Also, students develop basic orientation in programming environments by modifying code so as better to suit their experiments.
