摘要

人们普遍采取保持身体距离的做法来限制COVID-19的传播,这种做法被认为包含数学思想,可以作为未来教师练习数学问题的背景。本研究的目的是在符合数学任务标准的物理距离背景下,调查准数学教师所提出的数学任务的概况。数据收集自印度尼西亚泗水一所公立大学的33名准教师所提出的66项数学任务,这些教师参加了一个基于问题提出任务的计算能力评估课程。首先将所提出的任务划分为可解决任务和不可解决任务,然后将其进一步划分为语境使用水平和认知过程水平。结果表明,在给定任务中嵌入的上下文使用水平从零到一阶不等,只有少数给定任务被编码为具有二阶上下文。在认知过程的层次上,大多数任务都达到了理解的层次,只有少数的推理任务被识别出来。有趣的是,所有编码为包含二阶上下文的任务都被归类为推理任务。本文讨论了在数学任务设计中使用物理距离和教师教育干预来设计数学任务的一些含义。

Prospective teachers’ design of numeracy tasks using a physical distancing context
Physical distancing, which is widely practiced limiting the spread of COVID-19, is recognized to contain mathematical thoughts that can be harnessed as a context for prospective teachers’ practices of mathematical problem posing. The goal of this study is to investigate the profile of mathematical tasks posed by prospective mathematics teachers using the context of physical distancing that meets the criteria of numeracy tasks. Data were collected from 66 mathematical tasks posed by thirty-three prospective teachers at a public university in Surabaya, Indonesia, attending an assessment course of numeracy based on a problem-posing task. To analyze, the posed tasks were first identified as solvable or unsolvable tasks and then further categorized into the domains of the level of context use and the level of cognitive processes. Results show that the level of context use embedded in the posed tasks varies from zero to first order, with only a few of the posed tasks being coded as having second-order context. Regarding the levels of cognitive processes, most of the posed tasks reach the level of understanding, with only a small number of reasoning tasks identified. Interestingly, all the tasks coded to contain second-order context are classified as reasoning tasks. Some implications regarding designing numeracy tasks using physical distancing and interventions in teacher education related to numeracy task design are discussed.
