The Oche – Probability Dart-Throwing Simulation

Author / Site: Custom Interactive Tool (embedded HTML application)

Summary: The Oche is an interactive, browser-based simulation in which learners assign dart throwers to boards and observe probability outcomes through repeated virtual throws. The tool appears to model skill distributions and generate experimental trial data visually, allowing users to compare expected versus observed results. It includes roster management, board assignment mechanics, and real-time outcome tracking.

Relevance to Module: This simulation connects directly to the module's focus on probability concepts by letting students generate experimental probability data through repeated trials, mirroring the structure of a real-world probability experiment. The dart-throwing context provides an engaging, tangible scenario for exploring sample spaces, event outcomes, and the convergence of experimental results toward theoretical probability as trials increase.

Pedagogical Purpose

An instructor would include this resource as a hands-on practice and exploration tool that brings abstract probability concepts to life through active experimentation. By running repeated trials and observing how frequencies stabilize, students work toward MO3 (differentiating theoretical vs. experimental probability and understanding the Law of Large Numbers) and MO4 (interpreting calculated probability values in a real-world decision-making context). It also supports MO1 by encouraging students to think systematically about the sample space of outcomes for each board configuration.
