TASKS PROPOSED BY PROSPECTIVE TEACHERS OF THE FIRST SCHOOL YEARS TO TEACH PROBABILITY

ABSTRACT Recently we have witnessed the deepening of the teaching of Probability and Statistics in basic education, where it is important to investigate if the knowledge of prospective teachers is adequate to teach these subjects. 53 students, who were attending the 2nd year of the Bachelor's Degree in Basic Education at a university in Portugal, were asked to solve various questions on probability. We study only the one that refers to the didactic dimension of the prospective teacher's knowledge, when they establish tasks of probability suitable for students of the primary education. In the results obtained, it was found that the majority of participants presented inappropriate tasks to the cognitive level of the students for whom they were intended, and they were generally too difficult and without reference to uncertainty. The tasks were very similar to the learning that the prospective teachers themselves have done under the topic of probability in their previous training.

摘要 近年来，基础教育阶段的概率与统计学教学不断深化，探究准教师是否具备胜任该学科教学的知识储备，已成为一项重要研究议题。本研究选取葡萄牙某高校基础教育专业大二的53名学生作为研究对象，要求其完成多道概率相关题目。本次研究仅聚焦于其中一类题目：即准教师为小学阶段学生设计适配的概率教学任务时，所体现的教学知识维度。研究结果显示，绝大多数参与者所设计的任务与目标学生的认知水平不相匹配，整体难度偏高且未涉及不确定性相关内容；这些任务与准教师自身在前期培训中所学的概率相关学习内容高度相似。
