Ratings

Overall Rating:

4 stars
Content Quality: 3 stars
Effectiveness: 3 stars
Ease of Use: 4 stars
Reviewed: May 14, 2005 by Psychology
Overview: A simple and effective demonstration of the binomial distribution using a
Pachinko-like marble-drop simulation.
Learning Goals: By manipulating the "bounce right" probability and the "number of bounces" the
marbles make as they drop, students can observe the effect upon the frequency
distribution.
Target Student Population: This demonstration would be effective for high-school and college math and
statistics students.
Prerequisite Knowledge or Skills: Some basic understanding of probability would be helpful, but not essential, to
derive some benefit from this simulation. This is not a site to which students
could be sent without direction. A context is needed in order to truly
appreciate what the site demonstrates.
Type of Material: Simulation - probably using Flash.
Recommended Uses: This would be a handy reference in introductory math and statistics courses.
Technical Requirements: None.

Evaluation and Observation

Content Quality

Rating: 3 stars
Strengths: For what it is, a simple demonstration, the quality is high.
Concerns: No explanation is provided - the site would be much-improved if an introduction
and conclusion were provided. How the site functions is not intuitive, yet no
guidance is provided.

Potential Effectiveness as a Teaching Tool

Rating: 3 stars
Strengths: The demonstration is easy to use and simple to understand.
Concerns: There is no explanatory text accompanying the simulation. Most users would
benefit from a description of the binomial distribution and a brief introduction
to the factors being demonstrated/explored in the simulation.

Ease of Use for Both Students and Faculty

Rating: 4 stars
Strengths: Very easy to use.
Concerns: Directions are needed.
