摘要

本研究旨在探讨初中生正规性、概率性决策技能教学的理解与效果。两个具体目标是确定(1)中学生是否能够理解概率决策方法,以及(2)接触建模方法是否提高了中学生的决策能力?开发了decision学习单元来提供上下文。这个学习单元整合了数学、科学和决策概念。学生在一般决策测验的测试前和测试后的成绩差异有统计学意义,说明学生在中学阶段可以学习正式决策,提高决策能力。种族和性别变量对测试前和测试后的分数没有统计学上的显著影响。

Cognitive Development Effects of Teaching Probabilistic Decision Making to Middle School Students

This study investigated the comprehension and effectiveness of teaching formal, probabilistic decision-making skills to middle school students. Two specific objectives were to determine (1) if middle school students can comprehend a probabilistic decision-making approach, and (2) if exposure to the modeling approaches improves middle school students’ decision-making abilities? DECIDE learning unit is developed to provide the context. This learning unit integrates mathematics, science, and decision-making concepts. Differences in students’ pre- and post-test performance on a general decision-making test were statistically significant, indicating students can learn formal decision making in middle school and improve their decision-making abilities. Both race and gender variables were shown to have no statistically significant effect on pre- and post-test scores.
