The Approach of Winner-domain to Selecting Members for High School Team Participating in National Excellent Student Competition

Abstract

In Vietnam, every year, several competitions for high school students in different disciplines are organized at multilevel, provincial and national, with highly valuable prizes for winners. The problem to be solved by educational managers is how to efficiently select students for their school teams. This study proposed the approach of winner-domain to solving the selection problem by applying two following strategies: (1) students with performance similar to the winners of previous prizes are more likely to win next prizes; (2) the selection of team members is based on the “False Leaving out Better Than False Selecting” rule. This study conceptually defined the winner-domain which is the domain of the performance of winners to select team members. The algorithms forming winner-domain and the process selecting team member were installed. The approach was experimentally applied and evaluated at a high school in Southern Vietnam. The initial achievement showed that the proposed approach outperformed the previous methods which choose team members based on learning or testing outcomes.
